The staple -is operatiom. formed atthe nQse, lof the armv-Q. with its 1 legs or points upstanding, and is .'driven -from the place it. is formed by the driver -upward into the work. -The staples` are formed from staple wire 4 which-.is drawn from a suitable reel 6.'

As shown in F'ig. 5 the staple wire 4: is

- fed upward through a guide tube 7 through l tive machine the staple is' formed. at thev v.nose of the machineanddriven from that .3 3 point into the'work. Thisis. particularly.

The wireis then severedby coaction oicutting edges 11 and 12 formed respectively on the -under side of-the movable. former 13 and the upper ledge. of bearing 8 (see Fig. 11).' Immediately. followingA the severing operation the' -severed end of the wire is bent atright angles beneath the loop bar 9 by the former 13 moving to the leftas shown inFig. 7. The' former 13 is then moved 'upward by a lifter 14 b endin the wire'upward about the loop forming the other leg of the- 'bar 9 van staple. The driver 5 then rises forcing the movable loopbar 9 out of line `through-the action of a cam.1ug 15 (seeFigsJ12, 13 and la), and drives the'staple upward into 'the work.

Thus, it wn'l be noted thatin the illustraadvantageous in that it eliminates the' necessity of transferring the staple.lv from. vthe placewhere itis formed to .the pl'ace where it is driven. y

.As'shown in Fig. 10 the former 13 re. ciprocates horizontally between -arms 16 and 17 'of the lifter-14,- arm '17 being so 'constructedgas' toaccommodate the rearward-throw' of the former 13. The `former is provided with a groove 18 (see Fig. 16) 'to receive and guide' the-staple legwhen theffo'rmerl'l?, is

moved horizontally and verticallyl tocomplete the formation 'of the, staple. '1t -willv be noted thatl the former 13 first is moved -ihorizontally from the nose of the machine thereby 'cutting the wire and` bending it at right angles, and then is moved lvertically i forming the second leg of thestaple about 'the loop `bar 9.` As shown -in Fig. 11 `the cutting edge' 11.v of the former 13 is formed at an angle of approximately/150'@ the horizontal and` the upper edge 12 4of bearing f guide tube 7, bearing :8,in front of the former 13, and-between loop bar 9 and bearing. 10 is drawn from supply reel. 6 by coactin feed and

means, for example, by the instrumentalities shown `in the drawings which .will nowr 4be described.

The staple'wire feed pawl 21- is operated by a lever 21. pivotally connected to one end of lever 21", the other end of which is pivoted. to the frame of the machine at 21c the lever 21b carryinga roller 21dcontacting with Cain .-21e .on the'ishaft 23. VThe. roller 21@l isheld against the'c'am 21e by means of spring 21f.

The former 13is reciprocated horizontally through eonnectingrod 13a' having a's'lotted block. 13"v at its rear. end through which the shaft 231 passes. The block 13b carries a roller 13c which contacts withacam 13d on the shaft 23- through the` action of spring 13". Said spring is so arranged as to quickly return the former 13 to its original position, as shown in Fig. 5, .when the roller 13c passes the projection on thecam 136.` Theformer 13 is moved' verticallythr'ough 'the action of the lifter'14.

The lifter 1 4- is operated through the fulcrumed arm 14 connected to the lifter 14 by a pin andslot connection 14", and carrying a roller 114 at its rear-extremity which roller contacts with a cam 14d carried-bythe shaft 23. The-roller 14 is held in contact with the vcamV 14d by means of spring 14.

Thestapledriver 5 is-ope'rated by'a ful; crumed lever 5a having fits lfrontend con? neeted to the'l staple-'driver by a pin and slot connection 5", and having its rear end provided witha roller 5c engaged by a cam 5d von the shaft 23, said cam having 'a' projection tooperate the lever to give the staplel driver a quick up stroke and allow its prompt` return through spring 5..

As will be understood-,the vcams are' so the action of timed and the'l arrangement of the pa'rtsia` the. loop bar 9 to` return to initial position through the action' of a spring 24, the former 13 is returned to' initialposition `by the spring 13 andthe s 'taple wire Jeed' mechanism then advancesthe wire t v:tor another staple upward to position between the loop bar 9 and the bearing 19.

Wh-ich it may loe-lengthen may be desired.- At each rotation of'- the-- essaies ing and clinching device to cooperate .with the staple driver is carried atthe end of arm 3. This device as shown consists of a vertical plunger provided with' a -rack 31 meshing with a segmental gear 32pivoted at 33.` The segmental gear 32is provided with an arm 34 t0 which is'pivoted a link 35 connected to a cam lever 36 pivotedat 37 and carrying a roller 38 engag ing a cam 39 car ied byftheshaft 23 said roller being .heldr' against said cam by, a

driver to' clamp the box head or end dur1n a stapling operation, and tofserve as' an anvl or clincher to oppose the action of the staple' driver and clinch the ends of staples which maybe driven-through the work. The tim-v ing should be such' that the plunger clamps the Work'before the' staple is dr1ven. The

plunger rises andA releases the Work after the-driving of each staple, enabling the operator to move the box on the stapli'ng'arm the required distance foridriving the vnext staple. .n

The manner of using the machine, will be clearlyv understood by -those skilled in' the art, and-is indicated i'n Figs. 1 and 25 of the drawings showing anA ordinary Wirebound box with foldably'connected side and bottom sections provided with cooperating end cleats and heads or'. ends arranged in? side the cleats to be stapled thereto.' ln performing the stapling operation, the end or head board-rests upon the staplingarm asshown in Figure.,7 1, and the operator manipulatesthe boxon said arm While operating the machine. successively to drive a ron1 of staples through each cle'at; that is to say,

through the head or end board'v along linesA which .cause the staples -to Ypass into the cleats, and in this operation the-tapering nose or terminal of the stapling arm serves as a guide for. enabling the operator to posi- 'tion the WOTk and t0 gauge the staples from ythe box sides. 1. f .y

' Power for operating the machine may be applied in 'any' suitable mannen .as for-'in stance, by the power pulley' 45 shown in Figure 2, which may be controllably' clutched to the shaft '23 by any suitable clutch mechanism.

From the foregoing description vit will be understood that one practicable process em.

-bodying features of this invention comprises the feeding of a wire to a desired staple driving point in such amanner that the end portion of the Wire forms one leg of a staple in position to be driven, 'severing the wire a-dis tance from its extremity and' bending the wire to complete the formation of the staple.

'Y '-1. A'machine for .use in at the driving point. Such a process is par. ticula'rly advantageous for inside box staplingoperations in that it -permits the forming 'of 'a staple in. aiconlined space, for Y example, closeto a box side or in a 'box corner. Other advantages resulting from the described-processwill appear to those skilled in the art. h Obviously .the present invention is not limited to :the specific details` of vmechanism aidpro'ceduredescribed above for illustration and it will be understood that it is'n'ot indispensable that all the features of the ined ir-shortened as f-vention'be empioyedgin a single machine or process since the featuresrmay be used tol advantage 'separately as defined in the subj jined claims.
