MACHINE Fon Application led June 2,

To all 'whom t may concern.'

Be it known that I, OsoEoLA C. THOMP- soN, a citizen ofthe United States, residing at White Plains, in -the county of Westchester, inthe State of New York, have invented new and useful Improvements in Machines for Use in Making Boxes, of which the following is a specilication.

This invention relates to machines for use in making wirebound boxes, box blanks or parts and particularly to means for severingvthe binding wire between box blanks or work assemblies.

The nature of the invention will be best-v understood by-reference to one form of machine containing an ,embodiment thereof,

which is shown for illustration in lthe .accompanying drawings.

The machine selected for illustration is a wirebound bx blank machine adapted for uninterrupted operation in making a plurality of wirebound box blanks in succession, continuous lengths of"binding wire being applied to successive assemblies of box materials; and the purpose of the invention in -I such illustrative embodiment vis to sever 'the binding Wire between successive blanks.

Staplers 2 and a relatively movable workholder 3 for assembled cleats andl side material for ablank or a succession of rfoldably related box sections.

The lwork-holder v3 is in the form Aof a' crculat'ing conveyer having work-positionin means for a succession of box blanks; sai conveyer comprising a pair of endless flink chains appropriately channel-shaped to receive the box cleats and' having spacer blocks 4 aixed thereon at intervals for determining proper relationship of adjacent box sections or of the .cleats andside material. for a blank and for spacing successive Box sections are successively assembled on the conveyer chains by placing cleats thereon in pairs and" laying sheets of side ina-- terial thereacross; or, if desired, an integral sheet for a blank may be placed upon a succession of cleats.

The conveyer Vchains run onhorlzontal guide vrails 5 and at the delivery end of the machine are, trained around the driven sprocket wheels 6 which may be rotated from the main shaft 7 by any suitable means; for instance, by the ratchet feed mechanism shown in Fig. 1, comprising a ratchetwheel manually `independently rotating the con-v veyer sprockets, for initial work adjustment or otherwise, and Jr'orzbiaking the conveyer sprockets at the completion of each feed step. l Suitable means for this purpose, are shown, No.

22, 1919, Serial No. 284,332.

As the work progresses beneath the Staplers, a plurality of continuous" lengths of binding wire drawn from suitable suppl)Y .along with the work by virtue of their at'-4 reels, not shown, are introduced in properA relation to the box sections to be stapled thereto, the wires being vled between'the rollers 13 and thence y'ub-nder the rollers 14 carriedby the stapler bodies, and are pulledtachment thereto at' pre c'eding points. Cerftain of theJwires aligned with the box cleats are stapled through .the sheets thereto so,

as to connect-such wirestobotht`he cleats and the sheets andsecure the latter` together;

' and intermediate wires are or may be stapled to thesheets alone and clinched on their under sides by coaction of the staple drivers with anvils 15 supported on the, cross-frame member 16.

The staplers2 may be ofthe type disclosed, for'example, in the aforesaid patent Y to Thompson, No. 1,258,625, comprising'combined 'staple formers and drivers adapted at4 every operation to cut and form staples from staple-stock wirejlfd thereto byrollers 17 and .to drive the' same over the lbinding wires' into` the work. Said Staplers are mounted on the stationary vcross-.head 18 and are actuated by the vertically reciprocating cross-bar 19 working in guides of the sideframe ,1 and operated by a pitinan 2O from-eccentric 21 -on the main shaft, there beind''similar operating connections at either side of the -machine. The feed rollers 17 for the staplestock wires are also operated from the main shaft by eccentric 22 and connectingrod 23 working a pawl and ratchet `device 24 for rotating the rollers intermittently. q

With the intermittent feed type of machine described, a staple is formed and y driven at every re'ciprocation of the crosshead 19 or so-'called upper stitcher bar, the staple being driven on the downward stroke thereof, while the` material is momentarily at rest, the extent of movement of the material betweenl successive operation of the tive positions of adjacent box parts` arel properly maintained during the wiring of such parts together, various constructions andl arrangements for these functions being already-known to the art.

, Referring again to the illustrative imav chine, as the work leaves thestapling mechanism, the finished blanks may be stripped from the conveyer chains'on to table bars 25 suitably supported at the delivery end ofthe machine. l.

Before the work 'is delivered to the table bars 25 and while it is still o'n the work convcause a wire-severing operation.'

yeyer, theffwi'r'tes connecting one blank and 'anothermay be severed by the automatic cutting mechanism presently to be described.

The binding f""wi-res are intended to be severed between one blank and the next4 in such manner` as to leave freewire ends projecting beyond the ends ofthe blank so that lwhen thel blank is folded'into box form these 'projecting wire ends may be twisted or otherwise secured together for closing the y box. To suitthis purpose thev materials for succeeding blanks are 'suitably spaced to leave between them a sufficientV length of wire to provide, whensevered, the desiredV4 free ends. Such spaces may be effected, for

example, by placing the group of work-positioning devices or spacer blocks for one blank somewhat ahead of the group for the next blank.

Mechanism for 'severing the binding wires is located at the delivery endof vthe machine directly behind the staplers and consists'o'f j a plurality of individual' cutters corresponding in number to the Staplers and adapted to be 'controllably operated at selected tunes vto Sever the wire between box blanks or work assemblies.

The individual cutters are secured to the back plates of the lower stap-ler bodies `carried by cross-bar 18 and are actuated-byv the vertically reciprocating cross-bar 19. through the medium of plunger arms 3() pivotally hung from studs 37 attached to the back plates of the upper stapler bodies.

Said plunger arms 30 are 'constructed and arranged to reciprocate normally with the 'upper cross-bar 19 without operating the cutters and atselected times are thrown into.

operating connection with the cutters to An individual cutter consists ofv the sta'- tionary knife 31 carried by the back plate of the cutter and the swinging knife 32 pivotally suspended from a p-late33-reciprocable vertically in guides 34 of the cutter casings and maintained in normal non-cutting position by a spring 51. Plate 33 carrying knife l 32 is adapted to be lowered and raised at selected times by the plunger 30 to effect a l wire-severing operation.

As best shown 'in Figs.'.7 to 11` inclusive,

knife 32 is beveled at its-lower extremity and l A its' cuttin edge 35 is formed in an opening' or not'ch 1n the knife so that' when 'the knife is lowered against a wire to be severed, the .wire will contact with the beveled extremity of the knife and forc'eit to one side against the action of a spring 36, as shown 1n Fig.

9.' Continued lowering of knife 32 will cause the cutting edge 35 to pass below the .wire, whereupon spring 36 will swing cutv ting edge 35 under the wire, which will then lie above cutting edge d5-of knife 32 and f below the cutting edge of knife 31 (see -F ig. 10) in position tolbe severed between knives 31 and 32, when knife 32 is raised, as shown in Fig. 11.

Plunger arm 30 for causing the lowering I and raising of knife 32, which is pivotally suspended from stud 37, and reciprocates y constantly in guides 38 of the cutter, is nor-v lmally maintained by a, spring 39 in inop Plunger arm 30 and :plate 33 carryingknife 32, are provided with controllable interlock ing means to effect a connection between the two for a severing operation. Such means may comprise the opening or notch 40 formed in plunger arm 30 .which is adapted` to engage a projection 41` on the plate 33 and carry the plate 33 and knife 32 down and up witharm 30. Y

For causing the plunger arm 30 and the platec33 to engage, means are provided to swing arm 30 as itdescends, toward the projection 41 soV that 'projection 41 will Snap into notchv40 when they'meet. Such means vmay consist of the sprin -pressed trigger 42 carried by a-block 43 a justably secured to a bar 44 slidably mounted in the cutter casings; said trigger42 being adapted to enter opening 45 the cutter casing and engage plunger arm 30 to swing it toward projection 41 and maintain it in such position during a wire-severing operation. It will be noted that the lower lextremity of plunger arm 30 is beveled at one side to engage trigger 42 and at the other side to engage' projection 41.

Trigger 42 is caused to enter opening 45 at 'proper ,times for av wire-severing yoperation by movement of bar 44 against the action of spring 46. Mechanism is provided for moving bar 44 at proper times to effect a wire-severing operation. Such mechanism may consist of the cams 47 adjustably secured at selected points to the conveyer chains 2 by'set screws 48 or in any other suitable manner and the lever 49 pivoted at 50 to the cutter casing of one of the outside cutters and preferably. pivotally connected at its upper end'to the compression spring 54 carried by bar 44. The lower end of lever 49 normally hangs in the path of travel of the cams 47 so that movement of a cam 47 against-the lower-end of lever 49 will cause lever 49 to pivot about point 50 and, by compressin against the action of spring 46. Movement of bar 44 to the right in Fig. 7 causes trig` ger 42 to enter opening 45 and, by contact'- ing with plunger arm 30, lto force itinto operating connection with the plate 33 to operate the cutter. The cams 47, as shown in Fig. 6, are constructed and arranged to move trigger 42 into operatin position in the path of plunger 30 and hol it there until the plunger arm has been lowered land spring 54, move bar 44- raised by the action of the cross-bar 19.' When a cam 47 has passed lever 49, bar 44 and lever 49 arereturned to initial position through the action of'springs 46 and 54. In the illustrative machine the cams 47 for controlling the operation of the cutters are attached, for. convenience, to one lof the spacer'blocks 4,` preferably the last block for each blank, and are so constructed and arranged that the cutters will be thrown into operation at groper timesto sever the wire at the desire distance from ed es of the -'work and after staples havebeen riven into the oncoming box materials.4

For disengaging plunger arm 30 from projection 4l when, trigger 42 is released, plunger arm 30 is providedv with a cam surface 52 ada ted to engage avcam surface 53 in the gui e 38 after the'completion ofa wire-severing operation.

It will be noted'that the bar 44, which is controlled andactuated by the work-forwarding means through the cams 47, passes `through all the individual cutters and is provided with a block 43 and trigger 42 for each cutter so that the shifting of bar 44 through the action ofcams 47 on lever 49 causes a trigger'42 to enter each cutter and effect an operatin connection between plunger arm 30 and t e knife 32; thus, all the cutters areoperated together and the wires` will be uniformly severed. v

It will also be noted that the cutters are actuated ,by the so-called upper stitcher bar 19 whichalso'actuates the Staplers, and that the wires are severed upon the up stroke of said stitcher bar.' One advantage, among others, Ain severing the wire upon the up stroke of the upper stitcher bar is that it insures the driving of at least one staple into the oncoming box materials to hold the wire in position before it is severed; a staple lgeing driven upon each down stroke 'off Said` The operation of an individual cutter is clearly illustrated in Figs. 7 to 11 inclusive. In.Fig."7 the plunger arm 30 is descending and' the controlling cam 47 is about to en gage the lever 49. In Fig. 8 the cam 47 has engaged lever 49 and pivoted it about its pivot point 50, thereby causing trigger 42 to enter the cutter and throw plunger arm 30 into engagement with plate 33.v In Fig. 9, plunger arm 30 is forcing knife 32 downward against 4the wire to be severed and the wire is swinging knife 32 to one side. In Fig. 10, knife- 32 has lsnapped in under the wire and plunger arm 30 is about to start upward to effect a severing opera- 119l and "plunger arm 30] will'r reciprocate idly in'guides 38 until the next cam 47 engages lever 48. 2 y

It will be noted that vknives 31 and 32 are lboth maintained normall in inoperative o- -sition above the plane o the work and t at by lowering swinging knife 32 against the Wire to be severed, it will be swun to one side by the wire and its cutting ege will snap in under the wire in. position to carry the wire up with it whenl raised and cause the wire to be severed between the cutting ed es of the' knives 31 and 32. Thus,v it wil be seen that while both cutting members are normally maintained above the plane of the work during the intervals between cutting operations the swinging cutting member automatically assumes an operative position below the wire when 'lowered against it and performs a severing operation when raised. f It .will also be noted knife 32 is located behind the stationary 4knife 31 in the line of travel' ofthe work.

Thus the. severed end of the wire attached to the completed blank will be raised with the movable knife and the severed end of the wire'wattached to the oncoming blankAv will be held below the operating plane of the cutting members and will be. free to advance without buckling when the oncoming blank is a ain` moved forward.

Power or operating the machine may be' applied in any suitable manner as, for-'instance, by-power pulley 55, shown in Fig.

.2, which may be controllably clutched to the shaft 7 by any suitable clutch mechanism.

Obviously, the resent invention is not limited to the particular embodiment shown and described but may be variously embodied`el and theparticular construction shown may be variously modified, as will appear to those skilled in the art. Furthermore, it is not indispensable thatv all the features ofthe invention be used conjointlysince they may be used to advantage in valrious different combinations and sub-combinations.
