H E. inl WWII" 1 m I its application to Jeannine son ii Application filed. December 1 known that l, Ennns'r Eitnnson'; a n of the United States, residing at Chi- I in the county of Cook, in the State of ois, have invented new and useful 1m? rovements in Machines for Use in taking ones, of which the following is a specifica- The invention relates to machines for use making boxes and particularly to maci nes for use in making wirebound bones, c es, blanks or parts thereof.

Among other objects the invention is intended-to provide a machine of the class described havingimproved. means for severing the binding wire between successive box assemblies or parts.

The nature of the invention will be best understood by reference to one form of machine containing an embodiment thereof, which is shown for illustration in the accompanying drawings.v

The machine selected for illustration is a wire-bound box blank machine adapted "for uninterrupted operation in making a number of wirebound box blanks in succession, continuous lengths of binding wire being applied to successive assemblies of box materials; and the purpose of theinvention in such illustrative embodiment is to sever the binding wire between successive assemblies of box parts.

@bviously the invention is not limited in machines of this particular type. i

In the drawings: Figure 1 is a side elevation of the illustrative box blank machine, omitting the receiving end of the Work conveyer. 1

Fig. 2 is an end elevation, looking at the delivery end of the machine.

The illustrative machine comprises,- between supporting side frames 1, a gang of EMERSQN, 0F CHI-CACHE ILLINUIS, .ASSEGNOH C CDIEFMTY, U1 HITTERY, MAZNE,

across said clc a relatively movab' "mbling cl blan ring she or. it des11ed.slatteti side material rate bl; nl; may oe laid The conveye: chains run on horizontal. guide rails 5 and the delivery end of the machine are trained around the driven sprocket wheels 6. which may be rotated from the main sh it T by any suitable means, for instance, by the ran feed mechanism shown in Fig l, comp ratchet wheel 8 and co-actingfeed pawl carried by lever 10, which 1S operated through rod 11 from eccentrlc l2.

With the type of feed mechanism de son No; 1,258,625 dated March 5.1918, and- -in the pending application ofS. F. Bauwens filed March 22, 1919, being application Se rial No. 28%,332.

As the work progresses beneath the sta- CIT plers, a plurality of continuous lengths of binding wires 13, drawn from suitable supply reels, not shown, are introduced in ing pulled along with the work byvirtue of their attachment thereto at preceding points. Certain of the wires aligned with the box cleats are stapled through the sheets thereto, so as to connectsuch wires to both the sheets and cleatsands'ecure the" latter together; and intermediate wires are-or maybe stapled to the sheets alone and clinched on the under sides by the co-action of the staple drivers with anvils 16 supported on the cross frame 17.

The staplers 2 may be ofthe type disclosed, for example, in the aforesaid patent to Thompson No. 1,258,625, dated March 5, 1918, comprising combined staple formers and drivers adapted at every operation to cutand form staples from staple stock wire 18, fed thereto by rollers 19, and to drive the same over the binding wires into the work Said staplers are mounted on the stationary cross head 20 and are actuated by the vertically reciprocating cross bar 21 working in guides of the side frames 1 and operated by a pitman 22 from eccentric 23 on the main shaft there being similar operating connections at either side of the machine. The feed rollers 19 for the staple stock wires are also operated from the main shaft by eccentric 24: and connecting rod 25 working a pawl and ratchet device 26 for rotating the rollers intermittentlyj With the intermittent feed type of machine described, a staple is formed and driven at every reciprocation of the cross head '21 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 between the successive operations of the staplers determining the spacing between successive staples.

It will be understood that-thespecific machine here illustrated is but one illustrative example of a machine to which the invention is applicable, in which box parts are successively wired'together by effecting relative progression between work and fastenersetting mechanism, and in which desired relative positions of adjacent box parts are properly maintained during the wiring of such parts together; various constructions and arrangements forthese functions being already known to the art.

Referring again to the illustrative machine, as the work leaves the stapling mechanis'm, the finished blank may be stripped from the conveyer chains on to the stripper bars 27, and the wires connecting one blank s ao with another may be severedby the automatic cutting mechanism presently to be described.

The binding wires are intended to be severed between one blank or group of box parts and. the next in such amanner as to leave free wire ends projecting beyond the ends of the blank so that when the blank is folded into box form, these projecting wire ends may. be twisted or otherwise secured together to close the box. To suit this purpose the materials for succeeding blanks are suitably spaced to leave between them a sufficient length of wire to provide, when severed, the desired free ends. Such spacing may be effected,- for example, by placing the first spacer block for a box" blank the desired distance in the rear of. the last spacer block for the preceding, blank or by inserting elongated spacers between-successive blanks.

Mechanism for severing the binding wires ,is arranged at the delivery end of the machine and perferably at such a distance from the staplingplane as to insure the driving of a plurality of successive staples, three for instance, in each blank before severing the wires; thus the wires will be firmly held against slipping duringthesevering operation. a

The illustrative wire severing. mechanism comprises a gang of individual wire cutters 28, corresponding innumber to the staplers,

and arranged directly behind the staplers in the line of travel of the work. Said cutters are normally maintained in inoperative or inactive position, and are adapted upon pres entation of a cutting space between blanks or other pieces of work, to enter said spaces and engage and cut the wires.

As shown the cutters are hung fromva rocker shaft 29, supported at either side of the machine by notched arms 31, so as to drag over the work and be held thereby in non-cutting position, and so as to drop or swing into a s a vc between blanks when such space is presented, and after the wire-severing operation tobe again raised to normal noncutting position by the ad'vancing'movement of the following blank; This is an especially desirable arrangement for work control of the cutting operation, in accordance with relative progression of the work; in such arrangement the swinging cutter bodies, or at. least one of them, if the several cutter bodies are asshown, splined to. shaft 29, typify a controller responsive to the passage of each of successively passing blanks or other pieces of work to be cut apart.

While said cutters will ordinarily drop or swing intothe spaces between box assemblies by force of gravity, to insure against possible failure, a positive means for swinging v at the lower end; a spring assa sin I suitably secured to the frame of the machine and connected to the lower end of a levee arm 48 splined to the shaft 29 as shown, in Figure 4.

To gauge and position the cutters from the edge of the oncoming boxblank or box part, when in operative position, and to hold the cutting knives and associated parts above the passing work, when in inoperative position, a gauge or shoe 45 issecured to a bracket 46 carried casing 33, which gauge 45 is so formed as to pass between the spacer blocks a and the outer channel flange of the conveyer chain when the cutter swings into operative posi tiomand abut against the edge of the-oncoming work. Said gauge may be appropriately formed to position the point of cutoff, relative to edges of the work, where de-' sired. When all of the cutters are splined to the shaft 29, asshown in the illustrative machine, it is preferable to secure the gauge or shoe to to the outside cutters only. it will be noted that the gauge 45 of the outside cutters rides directly over the cleats so that when the cutters are riding, in inoperative position, on slatted side material for a crate, the cleats will support the cutters and prevent them from dropping into operative position between such slats.

The individual cutters which are splined to rock shaft 29 each comprise a slidable bar shaped knife 35, having its cutting edge pressed knife 36, having its cutting edge 'on the upper side adapted to cooperate with knife 35 to sever the wire therebetween and means forcausing cooperation of said knives. As shown in Figs. 3 and at knife 35 slides in channel 34 formed by the casing and is held in proper position therein by spring 37 secured to the head of said casing, which said spring is so adjusted as to hold the cutting or lower edgeof knife 35 above the wire when the cutter swings into operative position as shown in Fig. 3. Knife 36 which is slidably mounted in bracket 38 secured to cas-' ing 33 is yieldingly held in operative position byv a spring 39. Movement of knife 36 to the left in Fig. 3 is limited by pin 41 which'engages the bracket 38. Knife 36. is beveled on its underside, as shown in Fig. 3, so that when the cutter swings downinto operative position against the oncoming work, the taut wire between box assemblies will force theknife to one side 'ainst the action of spring 39 and pass above the knife as shown in Fig. 3. Knife 36 by the ac tion of spring 39 will immediately snap in under the wire which will then be lodged below knife 35 and above knife 36 in position for the severing operation as best shown in Figs. 3, 7 and 9.-

T6" cause said knives to cooperate and sever the wire therebetween the cutter is at the lower end of the pawl 3:2 will'eng 353 will produce relative mov provided with mechanism to cause relative movement between the cutting edges of said knives when the cutter is moved by the ac 7 tion of the moving work.

Suitable mechanism for such purpose con sists of a pawl 32, pivoted on shaft 30 carried by the bracket 31. yieldiirly held in con tact with the knife by spring 44. so as to cooperate with a lug carried by knife aswill now be exp ained. is shown in Fig. l shafts 29 and 30 are so located relative to each other that the awl 32 and the knives 35 and 36 with their i sociated parts pivot on different centers. the parts are so related that when the c1. into operative position shown in ..otted lines in Fig. a pawl. will take the shown directly above the l cutter swings to the left 1 position shown in dotted and w hen ical g rig motion l, ative to the swinging motion of the knife nent between knife and knife 36 that to sa work pushes the cutter to dotted line positon in Fig. knife in lowing its arcof travel will 1. .L while the knife 35 held by pawl and following the arc of travel of the pawl. 32 will he ered'until thecutting edges of the knives meet and pass each other severing the wire therebetween.

Thus it will be seen that the cutter moves with the work during a severing operatior. and that such movement automatically severs the binding wire.

This is particularly advantageous in that it obviates the necessity of providing independent actuatiiig mechanism for the cutter properly timed to operate in correlation with the movement of the work and the staplers, the cutter auton'iatically operating without adjustment at proper times as the work progresses regardless of the action of the staplers 'and'the intermittent feed of the work. a

For-releasing the pawl 32 from lug i2 and the swin after the severing operation knife is provided with a cam surface 43 located directly above lug 42 and adapted to throw pawl 3:2 from engagement with lug 4:2 as the cutter swings upward by the continued movement of the work toassume the position on the wor: shown in full lines in Fig. 4. lVhen pawl32- is disengaged from lug 42 by the action of the cam surface 43 knife 35 is re turned to normal position by means of the spring 37. The cutter continues to ride on top of the box materials until the next space between box assemblies or box parts presents itself. As it again swings down into operative position against the oncoming box assembly pawl 32, snaps in above lug 42 in position to engage lug 42 when the cutter is again actuated by the oncoming box assembly.

In connection with Fig. 4 the diagrammatic views of F 5, 6, 7 and 8 will clearly explain the operation. Fig. indicates the position of ,the parts when in the downward swing of the cutter. The taut binding wire has just engaged the lower beveled surface of the knife 36 to move it to the right in Fig. 5 v

Continued descent of the parts is representedin Fig. 6 wherein the wire is displacing the knife 36. Thus the parts are brought to the position shown in Fig. 7, the knife 36 having snapped back beneath the wire and the wire being in position for severing between knives 35 and 36. g

Fig. 8 shows the wire severed between knives 35 and 36 by the movement of the cutter which causes the shearing edge of the knife 35 to pass the shearing edge of the knife 36.

After the severing operation the movement of the work swings the cutter upward until it rests upon the oncoming blank where it rides until another space between blanks presents itself.

It will be noted that the cutter is actuated by the movement of the work and operates while the work is moving. It will also be noted that the point of cut-off is always at afixed distance trom the edge of the Work and I from the stapling plane, said point of cut-.

off being controlled by the gauge which contacts with the initial edge of the work.

Among other obvious advantages of the mechanism described the cutters will -operate uniformly in relation to each of successively presented pieces of work, adjusting themselves to the ,work so that if by reason of irregularity in work-feeding, there should be variations in the position at which the cutting space is presented, the cutters will accommodate themselves thereto and will cut oif the wires at the point predetermined by the gauge, for which different sizes may be substituted according to the desired point of cut-off. a It will be noted further that the cutting operation is controlled and actuated by the workitself and that said operation is not dependent upon any indepemdeznt mecha' nism timed to sever the wires at proper intervals. An advantage of this arrangement among others is that the cut-off will operate to sever the wires uniformly at} desired points relative to the edges of the work,

' automatically without adjustment.
