To all whom 1' tmay concern:

Be it known'that I, Soomvrns 'Knars a" subjectbfthe'King of Great Britain, resid ingi'at Leicester, Leicestershire, England, haveinvented certain Improvements in Dieing-Out' Machines, of which the following description, in connection with the accompanying'drawings, is a specification, like reference characters'on the drawings indi- 'catinglike parts in the several figures.

Tlils invention relates to dieing out machines and more particularly to machines intended foruse in dieingout' thin sheet material, such as parts of uppers for boots and slices.

Someofthe objects of the invention are to provide'a dieingout' machine which shall be quick in operation andat the'same time shall be'so constructed that excessive pressure will notice imparted to th'edie in a dieing out operation; to provide a machine of an improved construction adapted to insure'that but a single blow will be'applie'd to the'cut ting die'when the machine'is started; and to provide a machine that may be used with greater ease and convenience by the operator than machines heretofore employed.

To these ends the invention consists in the features and combinations ofparts hereinafter described and referred to in the appended claims.

In the drawings,Figure 1 is a view in side elevation of a machine constituting one embodimentof the present invention; Fig. 2 is a view in perspective with parts in section of the upper portion of. the machine shown in Fig, 1; Fig. 3 is a view in vertical section of a portion of themachine shown in Fig. 1; F ig.4is a view in perspective of parts showing in a dismembered relation parts illustrated in, Fig. 3; Fi 5 is a view in front elevation with parts in vertical section of the power actuated means hereinafter referred to and'parts cooperating therewith; Figs. 6 and 7 are views similar to Fig. 5 showing the parts in different positions.

Referring to the drawings, the reference numeral 1 indicates a frame upon which the parts hereinafter described are mounted. The frame 1 is provided with a vertical web 4 and-a horizontal web 6 to the faces of which is secured a bracket 8. The bracket 8 carries at its forward end a wooden block 10 which constitutes a. cutting bed. The block 10 rests upon a base 12, said base having a depending. convex extension 14 which rests in a concave seat formed'in the upper face of the bracket 8. The base 12 is also provided with :1. depending stud 16' which extends through an aperture formed in a web 18 upon the bracket. The lower end of the stud 16 is threaded to receive clampi' g. devices 20 whereby the base 12 may lie clamped upon the concave seat in the bracket 8. The base 12, which is of rectangular shape in plan, is provided at each corner with a vertical web 22 extending diagonally of 'the base, and each web 22 is connected to the bracketS by. bolts 2-1-- which are constructed for adjustment in length. It will be seen that by manipulating the bolts 24: the base 12 and cuttingbed 10 may be adjusted'to bring the upper surface of the bed into a parallel relation with the lower'face of the presser member hereinafter described.

The bracket 8 is provided at its rear end with a vertical bore of two diameters, as shown in" Fig. 3. In the upper enlarged portion of this bore is received the-lower end of a tubular shaft 26, upon the upper end ofwhich is secured a presser member 28'projecting forwardly therefrom. In the lower portion of the vertical bore in the bracket 8 is arranged a coiled spring'30. The'upper end of the spring 30 transmits pressure to the tubular shaft 26 through a cap'plate 32 which is arranged within the lower portion of the shaft 26 and rests against a shoulder formed on the interior thereof? The lower end of the spring 30is engaged by a bottom plate 34 which rests upon the top of a plug 36 screwed into the lower end of the vertical bore in the bracket 8. Secured to the top plate 32 and passing centrally through the coil spring 30 is a rod 38, the lower end of which extends through a central bore formed in the plug 36. This 'bo-re-in the plug 36 is threaded and receives an exteriorly threaded sleeve 40 having a smooth inner surface. Upon the lower end of the rod 38, which is threaded for this purpose, is arranged an adjustable stop nut 42 above which is placed one or more washers 44 of compressible material, such as leather. It will be seen that upward movement of the cap-plate 32 through the action of'the spring 30 is lim ted by engagement of the stop upon the lower end of the red 38 with the lower end ofthe sleeve 40. Variation in the position ofthe limit of upward moveadjustment of the sleeve 40 in the plug 36.

Within the upper end of the tubular shaft 26 is'received a plunger 46 which rests u on a washer 48 supported upon a shou der formed on the interior of the shaft 26. The plunger 46 is arranged in a vertical bearing 50 formed upon the upper portion of the frame 1 and is splined in said hearing so that it is held from rotatory movement about a longitudinal axis and is free for vertical movement in said bearing. It will be seen that-the plunger 46 constitutes an upper bearing for the tubular shaft 26 so that saidshaft by its upper and lower bearings is securely held from lateral movement.

In order that the bracket 8 may be so po- .sitioned upon the frame 1 that the vertical bore therein will be in proper alinement with the upper-bearing 50 for the shaft 26, said bracket is secured to the frame by connections permitting its exact adjustment into a proper position. As shown 1n Figs. 1 and 3 the connections between said bracket and the webs 4 and 6 upon the frame 1 comprise bolts 52, successive portions of which are of different diameters and are threaded as shown in Fig. 3. It will be seen from this figure that by adjusting the several bolts 52 in the bracket 8 said bracket may be adj usted relatively .to the frame into' proper position. When a proper positionhas been secured, the bracket is clamped rigidly in position by the nuts upon the smaller end of each bolt 52.

In the upper end of the frame 1 is formed a horizontal bearing 54 in which is received a shaft 55 upon the rear end of which is arranged a loose pulley 56 and a fast pulley 58, a fly wheel 60 being formed integrally with the fast pulley 58. A belt shifter 62 is shown for transferring a driving belt from one pulley to the other. Upon the forward end of the driving shaft is arranged an eccentric pin 64 which constitutes a means for imparting a vertical reciprocatory movement to an eccentric sleeve 66 suspended upon the pin 64 and provided with a depending stem in which is reinovably secured a driving rod 68 by means of a set screw 70. The lower end of the driving rod 68 is received within a cavity formed in the upper end of the plunger 46. \Vithin the plunger 46 is arranged a contact piece forming a shoulder 72 engaged by the lower end of the driving rod 68 in the active operation of the machine. As will appear from Figs. 2 and 5, upon the right-hand side of the shoulder 72 is provided a space in which the driving rod 68 may move vertically without imparting movement to the plunger 46. The driving rod 68 is held in its inoperative position by a spring 74 which presses the rod against the right-hand side of the inner wall of the plunger 46, as will appear from Fig. 5.

' which the a manually operated lever 80 pivoted at 81.

upon the frame 1 for movement about a horizontal axis. Upon the lower end of the lever 76 is pivotally mounted a dog 82 which is maintained normally in the position shown in Fig. 5 by a stop pin 84 against dog is held by gravity. Arranged in a socket in the right-hand side of the plunger 46 in Fig. 5 is a vertical finger 86 which is held in said socket by a pin 88 and \IS pressed against the wall of the bearing 50 by a spring 90. The socket in which the finger 86 is received is so formed that said finger may be moved laterally by the lever 76 as indicated in Fig. 6. The upper end of the finger 86 is rounded off upon the side adjacent to the finger 82. The hand lever is maintained normally in the position shown.

in Fig. 5 by a spring 92 which holds the lever against a stop 94 upon the frame 1..

It will be understood that inthe operation of the machine the driving rod 68 is in continual reciprocation. To efiect an acting stroke of the presser'member 28 the hand lever 80 is depressed, moving the lower end of the lever 76 to the left in Fig. 5 and pressing the driving rod 68 into position over the shoulder 72, through the dog 82 and the laterally movable finger 86. In the descent of the driving rod 68 the plunger 46 will be depressed and the finger 86 will be drawn down with it. In the lower part of the downward movement of the plunger 46 the finger 86 will be drawn below the end of the dog 82 and will be moved to the right in Fig. 6 beneath said dog by the spring 90. The rounded upper end of the finger 86 facilitates the' movement of said finger beneath the inner end of the dog 82. In the upward movement of the plunger 46 the dog 82 will be turned upon its pivot by the finger 86 into a position wherein it is ineffective to transmit lateral pressure to the driving rod 68, as shown in Fig. 1. The driving rod 68 is then free to be moved into its inoperative'position at the close of the upward movement of the presser member. The movement of the presser member is thus restricted to a single reciprocation whether or not the operator at once releases the hand lever 80 after depressing it.

The spring 30 is so arranged that it not only imparts vertical movement to the tubular shaft 26 but also imparts a rotatory movement thereto. .To this end the cap plate 32 is held from turning movement in its seat in the lower end ofthe tubular shaft 26 by means of pins 96, upon said seat, entering recesses in the face of the cap plate 32. The upper end of the spring 30 is rigidly held in fixed relation tothe cap plate 32 by a screw 98, enteringthe stem of said cap plate and arranged in a recess 100 formed in a coilof the spring 30. The bottom plate 34c is similarly held in fixed relation to the bottom end of the spring 30 by a screw 102 arranged in a recess 10st in a lower coil of the spring. The bottom plate 34: is held from turning movement relatively to the plug 36 by rods 106 projecting from said plug through passages 108 formed in the bottom plate 3%. The plug 36 is held from turning movement in its bearing in the bracket 8 by a set screw 110 arranged in the bracket 8 in position to be forced against the side of the plug 36. It will be seen that by adjusting the plug 36 in its bearing the spring may be placed under such tension that the shaft 26 may be held normally in a )osition adapted to bring the presscr member at a certain part of the range of i s lateral movement, for example in a position atone side of the central portion of the cutting bed.

The presser member 28 is provided with a handle 112 upon its forward end for moving; it into a desired position over the cutting bed. The lower or acting face of the presscr member is formed by a plate 114 which may be adjusted vertically upon the presscr member by an adjusting screw 116, as shown in Fig. 1.

In the use of the machine shown, a cutting, die having been placed in desired position upon a skin supported by the cutting bed 10, the presser member 3% is swung by the operator into position above the die against the resistance of the spring 30. It will be found convenient to so adjust the spring 30 that the presser member is normally maintained thereby at the side of the cutting bed upon the left of the operator. The presser member 28 having been brought into proper position over the die and held there by one hand, the hand lever 80 is depressed by the other hand to bring into operation the power actuated means for depressing the presser member. The driving rod 68 is thus brought over the seat 72 in the plunger 46. In the next descent of the driving rod, which is in continual reciprm cation, the shaft 26 and presser member 28 are depressed against the resistance of the spring 30. It will be observed that the downward movement of the presser member is opposed by a progressively increasing resistance of the spring 30. The momentum of the power actuated parts of the machine in the downward movement of the presser member is thus gradually diminished and is a minimum at the limit of the downward movement of the presser member. The movement imparted to the presscr member is thus such that an excessive pressure upon the die does not occur. In the upward ncrement of the driving rod 68, the shaft 26 and plunger 416 are raised by the spring 30, following up the movement of the driving rod. In this portion of the operation of the machine the movement of the power actuated par-ts is accelerated by the expansion of the spring 30. In the rise of-the plunger 46, the finger 86 carried thereby, which in the downward movement of the plunger has moved into position below the dog 82, raises said dog into its inoperative position shown in Fig. 'i. As soon as the presser member reaches the limit of its upward movement the driving rod 68 moves out of contact with the seat 72, and said drivin rod and the eccentric sleeve '66 are move by the spring T l into inoperative position wherein the driving rod moves idly within the plunger 16. The dog 82 is maintained in the position shown in Fig. 7 until the hand lever 80 is released by the operator. when the parts return to the position shown in Fig. 5. After a dieing out operation has been completed, the presser member 28 is released by the operator and allowed to be moved to one side of the cutting bed by the spring 30. It will be observed that during the operation of the machine both hands of an operator are so occupied that he is prevented from inter-posing either of them in the path of any of the power actuated parts. As will be apparent from Fig. 1 the hand lever 80 is arranged at such a distance from the handle 112 upon the presser member. that an operator is unable to manipulate both simultaneously with a single hand.

It will be observed that in the machine herein shown the means for yieldingly sustaining the presser member serves also as a mean for moving the prcsser member over the face of the cutting bed. It will be obviOuS, however, that separate and independ ent means for performing these two functions may be provided without departing from the present invention.

By adjustment of the sleeve 40 in the plug 36 the normal tension of the spring 30 tending to raise the presser member may be varied. It will be observed that this feature permits the resistance oflcred to the power actuated means in its acting stroke to be varied and thus made of an amount suitable to secure the best results. For example, if the sleeve 40 is adjusted to draw down the cap plate 32 and apply an increased tension to the spring 30, the normal elevation of the plunger 46 and seat 72 is lowered so that movement is imparted to said plunger by the driving rod 68 during a smaller proportion of the acting stroke of the driving rod. The total resistance to the movement of the power actuated parts in the acting stroke of the driving rod is thereby reduced. The amount of movement imparted to the presser member is also reduced.

The arrangement of the plate 114 upon lit 9&1.

the presser member for vertical adjustment permits variation in height of the cutting bed or of the die to be accommodated. It will be obvious that the construction shown whereby the plate 114: is vertically adjusted permits variation in the limit of downward movement of the acting face of the presser member.

It may be observed that variation in the amount of movement imparted to the presser member could be secured by varying the eflective length of the driving rod 68, asby adjusting it vertically in the eccentric sleeve in which it is carried. Such an arrangement would also permit the amount of resistance offered to the power actuated parts in the acting stroke of the machine to be varied. It will be understood that this arrangement falls within the scope of the present invention. It is desired to cover herein any construction or'arrangement -wherein the downward movement of the presser member effected by power 'actuated means is opposed by a resistance which may be varied in amount.

The tension of the spring 30 tending to move the presser member laterally over the cutting bed may be varied by adjustment of the plug 36. It will be understood that such adjustment may be found desirable in order to give the presser member a normal position best suited to the convenience of the operator. that tension tending to move the presser member over the cutting bed may be aplied to the spring 30 in either a rightiianded or a left-handed direction. It will be commonly preferred, however, to arrange the parts so that the presser member is maintained normall in a position at the side of the cutting ed upon the left hand of the operator.

It will be understood that variations in the construction and arrangement of parts from that shown may be made without departing from the present invention. It will be also understood that features of the invention may be employed in relations different from that shown and that all of the features above referred to need not be included in a machine embodying the present invention: The machine herein illustrated as an embodiment of the invention is shown by way of example and not by way of limitat-ion.
