EMBOSSING-MACI-IINE.

. To all whom it may concern:

"Massachusetts, have invented a certain new and useful Improvement in Embossing-Machines, of which the following is a specification, reference being had therein to the acings, in whichcompanying drawings. u

The invention comprises various improve- .ments in embossing or printing machines.

The said improvements are designed more particularly for use in embossing or prlnt ng in gold, silver, and other transfer material, including color, upon leather and other material, as for instance upon parts of shoes and upon hat bands, belts, stays, and the like, although they are not necessarily restricted to such use in all cases. The invention includes various novel combinations and features of construction.

.The improvements comprised in the invention are illustrated in a convenient form ofembodiment in the accompanying draw- Figure 1 is a side elevation, partly broken away, of a machine containing the said embodiment.

Fig. 2 is a front elevation of the said machine.

Fig. 3'is a rear elevation thereof.

Fig. 4 is a view in vertical section mainly in the plane indicated by the line 4, 4, of Fig. 2.

Fig. 5 is a view similar to Fig. 4 but show ing the ram closed against the die.

Fig. 6 is a view of the lower feed-roll and its shaft or arbor, with the said roll in longitudinal section.

Having reference to the drawings,-

The illustrated machine is shown constructed with a frame comprising a base 1 and opposite parallel vertical side- cheeks 2, 2. The operating shaft 3 of the machineis. mounted 1n bearings in connection with the said cheeks. In practice, the said shaft will have combined therewith suitable driving connection and start-and-stop devices arranged to enable the machine to he started at'the will of the operator, and to cause the same to stop automatically at the end of a single rotation of the shaft 3, substantially as in the case-.of various known machines. The more important parts of the machine include the presser or rams and means for Specification of Letters Patent.

operating the same from the shaft 3; the die 5 coiiperating with the said presser or ram to make the impression or imprint, a heater 6 (Figs. 4 and 5) in connection with the said die, guides at A and B for the strip, a, of transfer material, which are located respectively at the arriving side of the ram and die and the departing side thereof, a pulhofi device 7 (Figs. 1, 3, 4 and 5) for facilitating the advance of the said strip to the working point and through the machine, and feedrolls 8, 9, for the strip.

As shown in Figs. 1, at and 5, the die 5 is fixed to the under side of a forwardly projecting portion ofa die-support 5 that is secured at the rear of such portion by bolts 5, 5 to the tops of the cheeks 2, 2, of the machine-frame. Thereby the die is mounted in position to cooperate with the movably mounted ran14. The space around and in front of the said forwardly projecting portion of the die'support, and the die, is clear and unobstructed so as to permit the article or material which is to be embossed or printed tobe presented and applied from the front in position for'the embossing or printtion, inasmuch as it permits the required portion of the work to be passed in between the die and the ram by an upward and rearward movement, and other portions thereof to hang down in front of the ram and the adjacent parts of the machine.

The mannerand means of attaching the die 5 to the die support 5 may vary in practice. In the present instance it is shown as having its back placed against the under face of the forwardly projecting portion of the die-support 5 and as belng clamped in place through being engaged at its ends by downwardly projecting portions of flanges formed on screws 5*, 5*, Figs. 1 and 2, the stems of the said screws entering threaded holes tapped in the opposite sides of the said portion of the die-support. For convenience insetting orpOsitioning the die upon the 110 2 die-support a gage 5", Fig? 1,\is applied to the said portion of the die-support at the rear of the placefor the die. The said gagecombined therewith the heater 6. The latter is in this instance an electric heater, al-' though the precise character and construction of the heater is not in all cases material, and I contemplate in practice varying the character, construction, and manner and place of application-of the same. As herein shown the electric heater 6 is contained within a chamber in the die-support, Figs.

4 and 5, the wiring for the heater being in-' dicated at 6. The die-support is made of heat-conducting material, so that the heat may reach the die attached thereto, and for the purpose of preventing loss and waste of 80 heat by conduction to the machine-frame heat insulating material 6 is interposed between the die-support'and the portions of the cheeks 2, 2, to which said'die-sup ortis applied, washers of such material (shown 85 best in Fig. 1) also being interposed between the heads of the bolts 5 and the upper surface of the die-support. A suitable switch and rheostat (not shown) will be included in the electric connections of the 40 heater in practice for the purpose of controllin the heating and the degree of heat.

he closing together of the ram and die for the embossing or printing operation, and subsequent separation and opening to. permit removal of the embossed work or material are provided for by mounting the ram upon a movable support and operatively combining the said support with an eccentric upon the operating shaft 3. In addition, provision is made for a yielding action of the ram in closing toward the die. The illustrated machine embodies ram-supporting and actuating devices arranged to provide for the said yielding action and embodying certainof the improvements which are comprised in the present invention. A different construction and arrangement of the actuating devices may be provided in practice, in case it should be deemed advisable to simplify the construction and reduce cost, or meet special considerations and re quirements in use, or in accordance with the views and wishes of the builder or purchaser of the machine. The ram 4 is shown sleeved upon one end of a post or stem 4 having the at 5 to accom-' main portion of its length contained within an elongated socket in a carrier 4 constructed with a strap 4 encircling the eccentr c 4 on the operating shaft 3. The eccentric 1n its rotation gives a reciprocatory movement to-the carrier 4", which carries the post 4 4 and ram with it in its movements, thereby causing the ram to alternately approach the die and recede therefrom. To guide the ram in its movements a radius arm or lever 4", which is hung by means of a pivotal shaft 4 between the upper portions of the checks 2, 2, is connected pivotally at 4' with the ram, as shown in Figs. 1, 4 and 5. The said radius arm or lever 4 is of open framework construction, with the forwardly projecting ends of its side-portions arranged so that they. receive between them a rearwardly projecting lug of the 'ram, the pivot 4 being engaged with the said ends and the lug as 35 shown. To secure the yielding action of. the ramin pressing the work against the die, the post 4 by which the ram is more immediately supported is made movable within the socket of the carrier 4 and a cushion ing means is combined therewith. This cushioning means comprises in the present instance a spring-controlled rocker or lever 4 which is hun or pivoted at 4 in the lower part of the carrier 4, it having a toe 4 which 5 engages with the inner end of the post 4. The controlling spring therefor is an expanding spiral spring 4 that is confined etween the free extremity of the lever or rocker 4 and an adjacent portion of the carrier 4 the opposite ends of the said spring being seated in pockets that are formed in the said end of the lever and in the said portion of the carrier respectively. The spring by its tendency to expand acts against the lever or rocker 4 so' that the toe 4 of the latter serves to support the post 4 and the ram 4, with the ram in its outward position relative to the carrier. \Vhen the thickness of work intervening between the ram and the die is such as to oppose sufiicient resistance to the closing movement of the ram to overcome the tension of spring 4*,the said spring yields and permits the lever or rocker 4" to turn on its pivot 4 relative to the carrier 4 To'enable the cushioning effect to be varied to meet requirements in practice, provision is made for adjustment of the tension of the spring 4". The means of adjustment comprises a'pin or stud 4 which is fixed by one end'to the carrier 4 at the center of the spring-receiving cup on the carrier and projects through ahole in the lever or rocker 4" formed 'concentrically with the springreceiving pocket'of the said lever or rocker.

The spring 4* [surrounds the intermediate portion of the-said pin or stem. The portion of the; pin or stud which projects at the front of'the lever or rocker 4 is screwthreaded and has applied thereto adjust- 1.30

ment and check-nuts a", a". By backing oil the said nuts the said spring is permitted to expand more or less and thereby its tension is reduced, while by turning the said nuts inward along the pin or stud 4 so as to corn press the spring more or less the tension of the spring is increased. Adjustability of the ram upon the post 4*? toward or from the die to suit the thickness of the work is secured by screw-threading the outer portion of the said post and applying thereto a nut 4 and connected gear 45*, shown best in Fig. 1, the said nut and gear serving as a collar to fix the position occupied by the sleeve of the ram upon the post. By turning the nut around the post, it and the ram are shifted lengthwise of the post. To provide for conveniently turning the nut by hand, a pinion 4* is mounted alongside the nut-gear 4 and in engagement therewith, this pinion having a thumb wheel 4 which enables it to be turned manually for the purpose of rotating the nut 4. The pinion 4 and thumb wheel 4 are mounted upon the carrier 4 by means of a journal 4! projecting from them and entering a bearing in a projecting portion of the carrier, in which hearing it is retained by means of the inner end of a screw 4, the said end entering an annular groove around the journal. To prevent the post from rotatingwhile the adjustment nut is being turned, a screw 4* is applied to the side of the said post, its end projecting from the post into a longitudinal slot 4 formed in'the carrier 4". This slot permits the post to move lengthwise within the socket of the carrier as the spring 4 yields under the closing pressure and expands when such pressure is relieved.

Suitable back-stops or gages 10, 10, are combined with the ram 4, at opposite sides thereof, to determine by engagement with the rear edge of ithe work the proper position of the work when applied to the face of the ram. Each of these gages or backstops has a body-plate which is'applied to the corresponding end or side of the ram and attached thereto by means of screws 10, 10, the said plate being slotted at 10 to permit the gage or back-stop to be adjusted in the direction from front to rear or vice versa.

The strip a of transfer material passes from the source of supply through the guide-system A, past and in engagement with the pull-off '2, then forward between the ram 4 and die 5, to and around the curved portion of a guide 11 adjacent the die, then rearward through the guide-system B, and then between the feed-rolls 8 and 9.

The guide-system A is located at the supply-side of the die and ram. It includes a aching-plate 12, which occupies an upwardly inclined position and serves to support the strip a as the latter passesthrough the said guide-system. The guide-system A also includes edge-guides 12 12, for the strip which are shown best in Fig. 3. The said edge-guides are located at opposite sides of the path of the strip a. They are adjustable toward and from each other to suit dilferent widths of strip. With the edgeguides are combined means for holding them in parallelism with each other, maintaining them in parallelism in all positions of adjustment, and keeping them securely in their adjusted position. To hold the edge-guides l2, 1 in their working positions and parallel with each other, as well as maintain them in parallelism in the dif ferent positions of adjustment, each edge' guide is connected with the plate 12 by a pair of parallel-motion links 12 12,- shown best in Fig. 3. Movement of the edge guides in the direction of their length will cause the parallel-motion links to swing about the points of pivotal connection with the plate 12, with resulting shift of the edge-guides toward or from each other, according to the direction or" movement. Thereby the adjustment of the edge-guides for varying the distance between them to suit the width of the strip a is efi 'ectedv To insure movement of the edge-guides in uni son and cause them to move inward or outward simultaneously and to the same extent in being adjusted, the two edge-guides are connected by means of links 12, 12, in other convenient manner, with an inter mediately located longitudinally arranged bar 12 This bar is mounted conveniently in position by being supported upon crossbars 12 12 which in this instance respectively lie upon the upper and lower ends,

respectively, of the edge- guides 12, 12 The cross-bars 12 12 are held in place by means of screws l2, 12', the stems of which pass through holes in the opposite ends of the said cross-bars and enter threaded holes that are tapped in the marginal portions of the plate 12. The longitudinal bar l2 is held in place upon the cross-bars 12 12 by means of screws 12 12, the stems of which pass through longitudinal slots 12, 1 12, in the bar 12 and enter threaded holes in the cross-bars 12 12 The slots i2, 12*, provide for longitudinal shift of the bar 12 and thus permit of the adjustment of the edge-guides toward or from each other. After having beenadjusted, the edge- guides 12, 12*, may be securely fixed in place, either by tightening the screws 12 12*, so as to clamp the bar 12 to the cross-bars 12 12 and thereby hold the bar 12 from longitudinal movement, or, without tightening the said screws 12, 12', by tightening the screws 12, 12*, so as to cause the crossbars 125,12 to press upon the edge- guides 12, 12, and clamp the latter firmly against the outer surface of the backing-plate 12. This latter mode of holding the edge-guides in their adjusted position has the advantage that as a result of the edge-guides being clamped firmly against the surface of the backing-plate 12 1t is renderedimpossible for either edge. of the strip a to enter between one of the edge-guides and the said backing-plate. When it is desired to adjust the edge-guides toward or from each other, it is of course necessary that the pressure of the cross-bars 12 12 upon the edge-guides should be sufiiciently relaxed to permit the edge-guides 'to slide beneath the cross-bars, and that the adjustment bar 12 should be free to slide longitudinally. The

"upper portion of the backing-strip 12 is curved forward toward the die and ram to provide a curved guiding surface for the strip a as it changes direction in leaving the guide-System A.

Between the guide-system A and the pulloif 7 the strip a is engaged by a device 13 which serves to take-up the slack in the portion of the strip which is passing through the machine. Thereby the strip is maintained at uniform tension within the machine, and uniformity in the extent to which the strip is advanced relative to the die at each feed-movement of the feed-rolls is insured. This take-up 13 in the present instance is in the form of a swinging bail comprising a transverse portion which rests upon the strip adjacent the curved upper portion of the backing-plate, and side-arms which are engaged pivotally with lugs 12, 12, upon the upper portion of the said backing-plate. The said bail rests by its weight upon the strip between the pull-ofi and the point at which it leavesthe backing-plate 12, and operates to maintain the strip uniformly taut. When the working of the parts tends to slacken the portion of the strip that is passing through the machine the bail swings so as to form a bend in the strip between the backing-plate 12 and the pullofi',.thus taking up the slack and maintainingthe strip at substantially uniform tension. In practice, a slight drag is applied to the strip before it arrives at-the take-up device, whereby the strip is held back at the supply-side of such device so that the latter operates effectively to take-up the slack arising within the machine as far as the feedrolls. This drag will be produced by applying in any convenient manner a slight resistance to oppose the travel of the strip from the'source of supply through the guidesystem- A. I have herein shown provision for creating and applying the said drag in the form of a small weight, 13, Fig. 3, resting upon the strip adjacent the lower crossbar 12 A continuation of the curved guide 11, extending upwardly and rearwardly above the die and die-support, constitutes a backing-plate for the guide-system B. The latter, as shown best in Fig. 2, corresponds in general construction with guide-system A, and comprises the parallel edge-guides 11, 11, parallel-motion links 11", 11", etc., connecting-links 11, 11, adjustment-bar 11 slotted at 11, 11, screws 11, 11, and transverse-bars 11 11. The upper-end-portion of the guide and backing-plate 11 is curved toward the entrance between the feed-rolls 8, 9, to provide for a gradual change of direction of the strip as it passes from guidesystem B to the feed-rolls.

The feed-rolls 8, 9, are located at the rear of the guide-system B, adjacent the curved end of the backing-plate 11. The shaft 8- of the feed-roll 8 is mounted in bearings in opposite stands 14, 14, which are made fast to the upper portions of the cheeks 2, 2. The shaft 9 of the roll 9 projects at its ends or journals into slots 14 in the said stands,

and within each of the said slots a block 9 enable the rolls to be separated from eachother whenever desired, a roll-separator is provided. In this instance it consists of a U-shaped frame 15 hung upon a transverse wire or rod 15 extending from one stand 14 to the other, the said frame having sidearms 15", 15*, which pass down alongside the ends of roll 9 and are formed with camportions 15, 15, which are disposed in front of the journals of such roll. A handle 15' is provided on the frame 15, by means of which the latter may be rocked to cause the cams to act against the said journals to'press the roll 9 away from the roll 8, overcoming the resistance offered by the springs 9, 9. The cam- portions 15, 15, are formed with projecting portions which act against the journals to prevent excess movement of the frame which would disengage the said camportions altogether from the journals.

The feed-rolls are rotated intermittingly automatically by. means of suitable actuating devices. Herein the said actuating devices comprise a crank 16 carried by shaft 3, connected by a rod 17 with a lever 18 hung upon Through the described devices an intermit-' tent movement of rotation is transmitted naeaaee to the feed-roll 8 from the operating shaft 3. The feed-rolls 8, 9, are geared together by spur- gears 19, 19, fixed upon their shafts so that they thereby positively are caused to rotate in unison slip of oneroll relative to the other being avoided. An eccentric friction-dog 18 mounted upon the adjacent stand 14 on the stem of a screw 18 and rotated by a spring 18, Figs. 2 and 3, to cause its eccentric portion to engage with the periphery of wheel 18", serves to prevent backward rotation of the feed-roll 8. To provide for varying the extent to which the strip a is moved along at each feed-movement, I employ a crank 16 of adjustable throw. In this instance the carrier 16 of the crank- -pin is slotted lengthwise at 16 and secured to a face-plate 16 on one end of shaft 3 by means of a screw 16 passing through slot 16 into the said face-plate. This construction permits the carrier 16 to be adjusted diametrically of the shaft 3 so as to enable the crank-pin to be set at the distance from the axis of said shaft 3 which is necessary to give the proper throw to secure the desired extent of feed-movement.

To hold the carrier 16 from turning rela tive to the face-plate, but still permit of the adjustment of the carrier diametrically with relation to the shaft 3, I may employ any convenient guiding arrangement in connection with the carrier face-plate. In the present instance pins 16 16 are oppositely located upon the carrier and parallel slots 16', 16*,are formed in the face-plate. These slots extend parallel with the diametrical line on which the crank pin is adjustable, and at opposite sides of the said line and the pins work in the said slots 16 16 To enable the feed-rolls to be rotated manually for the purpose of advancing the strip a at will, the roll 8 is furnished with a thumb-wheel 20, Figs. 2 and 3, fixed upon one projecting end-portion of its shaft 8 lVhen it is desired to make a backward or reversed shift of the strip, the rolls are separated by means of the roll-separator so as to release their grip upon the strip and permit it to be adjusted by hand.

As the ram closes against the die the pulloff 7 operates to pull from the source of supply and through the guide-system A. a sufficient length of the strip afor the next feeding movement of the latter past the die and as the "am separates from the die the pull-off slackens the strip within the machine concurrently with a feed-movement of the feed-rolls acting to draw the strip past the die. The pull-off and slackening action are provided for by mounting the ull-oif 7 upon the radius-arm or frame i the latter being linked at i? to the ram, as already explained, so as to he swung by the movements that are imparted to the ram. -Thereby the pull-cit is operated in unison with and by the ram. Each movement of rotation of the feed-rolls coincides with the slackening of the strip by the reverse movement of the pull-ofi, and consequently the feed-rolls merely operate to draw forward die, so that such portion holds the strip a separated from the face of the die. The said backing-plate and guide is movably mounted, and to it are. given movements which at the time of the closing of the ram toward the die for the impression cause the guide to recede relative to the die as in Fig. 5 so as to carry the said strip close to the face of the die, or into contact with such face; and subsequently, as the ram moves away from the die after the impression, causes the guide to follow the ram part way so as to detach the strip from the face of the die and separate it therefrom. lfhe further receding movement of the ram carries the latter away from the strip, as shown in Fig. 4. For the movable mounting of the guide, the combined hacking-plate and guide 11 is supported pivotally at 11 upon small stands 11*, 11

rising from the tops of the cheeks, 2, 2. The required movements are communicated to the backing-plate and guide, to rock the same upon its pivotal mounting, through connections between the same and the radius-arm or lever 4? of the ram 4. The said connections include a link 11 extending from the rear portion of the combined backing-plate and guide to a portion of the radius-arm or lever a at the rear of its pivot a. To provide for adjustment of the guide with reference to the die and the front end of the die-support, the link 11 is made adjustable in length by being formed in two parts or members which respectively are pivotally joined to the combined backingplate and guide, and radius-arm or lever 4 respectively, and connected together by means of screws 11", 11", one of the two linkmembers being longitudinally slot-ted to permit the said members to be adjusted relative to each other so as to vary the length of the link. By lengthening or shortening the link ii the downturned end of the hide 11 is lowered or raised relative to the die.

Simultaneously with the receding movement of the ram and the accompanying movement of the guide by which the strip a is separated from the face of the die, and detached therefrom in case it should tend to embossed or printed, in case it should tend to adhere thereto. After the feed movement by which the portion of the strip a which is to be used in making the next impression is Y brought into position between the die and the ram, the strip is held taut between the pull-ofl" 7 and the curved lower end of the guide. 11, so that thereby it is held definitely against displacement as by a draft of air or by contact of the Work therewith while the latter is being placed in position to be operated upon.

A difliculty experienced in feeding a strip of some length between a pair of feed-rolls is the tendency of the strip to work edgewise progressively in one direction or the other. I overcome this difficulty through the employment of an automatic guide by which tendency of the strip to swerve from the proper path is corrected. This portion of the invention involves broadly the employment of automatic strip-guiding means controlled by the strip and acting to restore the latter automatically to the proper path of travel in case it swerves from such path. In the illustrated embodiment of the invention the feed-roll 8 is arranged to counteract the said tendency. For the said counteraction, I construct and combine the roll 8 and its supporting shaft or arbor 8 so that when the strip a, in being fed, swerves toward one side or the other, the strip itself shall swing theroll into a position so inclined relative to the length of the strip that the rotation of the roll will carry the strip automatically back into the proper path. Referring now to Figs. 4, 5 and 6, it will be observed that in Fig. 6 the longitudinal bore that is made through the roll 8 for the reception of the shaft or arbor 8 is larger in'diameter than the portion of the latter which occupies the main length of the said bore, and that at midlength of the roll the shaft or arbor is formed with an annular enlargement 8* having a transversely rounded periphery and resembling the middle zone of a sphere. The portion of largest diameter of this enlargement fits the bore of the roll 8 at midlength of the roll. A screw 8 has its stem screwed into the enlargement, while its rounded or ball-shaped head occupies a radial hole 8 in the roll. The said head prevents the roll from displacement longitudinally of the shaft or arbor 8*, while the construction permits the roll to swivel relative to the shaft or arbor. In the operation of the machine, so long as the middle of the width of the strip a corresponds in position with the middle of the width of the enlargement 8", equal portions of its width of the portion of strip at the side of the swiveling point toward which the strip has swerved will carry the corresponding end of the roll 8 forward, thereby causing the said roll to swing into a forwardly in-- clined or angular position; The result of this will be that rotation of the roll in such forwardly inclined or angular position will exert a tendency to cause the strip to travel back to the middle position again. In this way the roll Will automatically guide the stri so that it normally will travel in the predetermined path. The side-guides of the two guide-systems-A, B, are located at equal distances from the proper position for the middle line of the strip, and inasmuch as the said guides, are arranged to move equally in opposite directions from or toward said mlddle line in their adjustments, and to remain parallel to each other in all their positions of adjustment, the said 'adjustments have no disturbing effect upon the path of travel of the strip which would interfere -with the attainment of the desired results in automatically guiding the strip by means of the swiveling roll 8.

For some classes of work, the strip a of transfer material consists of a strip of paper treated with paraflin charged at one surface of the strip with the gold or other printing substance. Proximity of the strip to the heater has the effect of softening the paraffin and decreasing its hold upon the gold or other printing substance. In other words "the effect of the heat from the heater is to render it easier for the gold,

or other printing substance, to strip from the paper-backing. The. result of this, in the absence of means to counteract this tendency, is a liability of the printing substance to strip from the backmg alongside the lines of the imprint made upon the leather or other work operated upon. When the feed-movements of the strip are closely proportioned to the size of the face of the die, so as to economize in the use of the printing substance this stripping of the printing substance from the backing alongside lines of the imprint upon the work will deprive portions of the backing within the limits of the next succeeding impresslon of portions of their charge of the printing substance and consequently the succeedlng imprint will be imperfect. To prevent this tendency, a cooling device is provided by means of which the softening of the paraiiin is prevented. This cooling device comprises in the present instance a mouth-piece 20 arranged to discharge a stream of air upon the portion of the strip a which is adjacent the die and heater. The

said mouth-piece is shown arranged above the pull-off 7, and so as to direct the said stream upon the reverse side of the strip below the heater. The mouth-piece 20 is attached to a short pipe 20 carried by the radius-arm or lever i In practice, a conducting pipe or tube (not shown) will extend from the said pipe 20 to a pump (not shown) or other source of supply for air under pressure.

The illustrated machine is adapted for use in operating upon the interior surfaces of the uppers of shoes by reason of the fact that the die-support and the die are of width and proportions adapting them to be received within the top of an upper, and the strip a feeds from the rear, forward past and around the die and the frontend of the die-support, and then rearward relative thereto. If the said strip were fed laterally from a source of supply at one side or. the other of the die and die-support, the portions of the strip stretching laterally outward from the die at one or both sides of the latter would interfere with the application of a shoe-upper to the machine for the purpose of being embossed or printed.
