28 Claims.

My invention relates to dieing machines more especially equipped for producing links for machine gun belts, and an object of my invention, among others, is a machine of this type for rapidly producing such links in an efficient and economical manner and which utilizes a minimum amount'of stock, thereby effecting a saving in this respect.

One form of a machine embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawings, in Which- Figure 1 is a top plan view of a die holder and parts mounted thereon.

Figure 2 is an end view of the same and including a portion of the punches.

Figure 6 is a view on enlarged scale in section on a plane denoted by the broken line 6-6 of Fig. 1.

Figure 7 is a similar view on a plane denoted by the broken line 'I--l of Fig. 1.

Figure 8 is another similar view in section on a plane denoted by the broken line 8-8 of Fig, 1.

Figure 9 is a perspective View illustrating the progressive movements of the blanks during formation by the punches and dies, the latter being omitted.

In the accompanying drawings the numeral 8 denotes the die holder of my improved machine which holder it will be understood is mounted on a bolster or bed in a manner common to machines of thisl type. A cam shaft 9 is suitably mounted in bearings Ill-II upon the die holder 8 and is 40 driven by means of a gear I2 meshed with a driving gear I3, the latter being driven from any suitable source of power as a connection with the crank shaft in the lower part of the machine.

A guide block I4 is supported upon the die holder 8 and a blanking die I5 is mounted upon the guide block as shown in Fig. 3 of the drawings. A stripper plate I6 is secured atop the die I5 in a manner common to structures of this type.

AA feed slide I1 is mounted for reciprocating sliding movement upon the guide block as between gibs I8 and a feed finger plate I9 is secured to the fed slide and has feed fingers spaced apart and projecting from the inner edge of said feed 25 mounted for vertical'reciprocating movement ina manner not herein shown but which will be readily understood by'those skilled in the art. The punch operates to cut a blank 26y from the strip 23 and in the embodiment shown herein forces it through the die I6 into a guide groove 21 in the guide block I4 and into the path of the feed fingers 20 by means of which the blanks 26 are passed along the groove underneath the die I5 to a position to be hereinafter described.

A forming die 28 is mounted upon the die holder 8, this die having a pair of rounded forms 29-30 spaced apart on its top, these forms merging into side forms 3I on the sides of the top of the die. Sliding formers 32 are mounted for sliding movement upon the die holder 8, these formers being spring pressed apart as shown in Fig. 7. They have recesses 33 to engage opposite sides of the blank upon the die 28. A plunger 34 supported on the punch holder 25 has recesses cooperating with the rounded forms 251-30, said plunger and sliding formers cooperating to impart a preliminary form to the blanks, as shown in Fig. 7. The sliding formers 32 and the plunger 34 are so relatively timed in their movements that the recesses 35 in the plunger engage the blank upon the forms 29-3Il before the recesses 33 on the sliding formers 32 engage the blank upon the side forms 3l. The plunger 34 is yieldingly held by means of springs 36 which act during the preliminary movement of the plunger to press the sides 3l of the blanks downwardly into a position opposite the recesses 33, and in the final movement of the plunger 34 the upper end of the plunger strikes the under side of the punch holder '25 and the blanks are then positively seated upon the forming die 28. The sliding formers 32 are operated by former actuating cams 38 upon former actuators 39 secured to and projecting from the under side of the punch holder 25 as shown in Fig. 7, the cams 38 being positioned to impart movement to the formers 32 after the sides 3'I of the blanks have been bent finger plate. The feed slide is operated as by downwardly to clear the formers as hereinbefore cribed. The formers are provided on opposides with guide ribs 48 to engage grooves in end of the guide block I4 and in a former die to be hereinafter described. The sliding form- 32 are spring pressed apart as by means of ings 42 located in recesses in the bottoms of ormers, as shown in dotted lines in Fig. 7. lfter the blanks are stamped to shape and forced through the blanking die I5 the feed gers are moved forward by the operation of e lever 2| on to therforming die 28 where preliminary form is given to them in the nner hereinbefore described. Projecting from .feed slide |1 underneath the feed fingers 28 l extending through a raised part of the guide ck |4 are pusher rods 43 which contact with e edges of the partially formed blanks on the ming die 28 and push said blanks from said ming die on to forming fingers 44--45 proting from a finger supporting slide 46 mountupon a slide support 41. The forming ngers e arranged in pairs and there are two sets of d pairs projecting from the slide 46. The n- 44 is arranged to receive a single knuckle 48 one side of the link and the nger 45 is ar- 2 aged to receive double knuckles 49 on the oosite side of the link, it being understood it when these links are assembled to form the .t the cartridges form the pintles extending rough the links 48-49.

lhe former die 4| has a pair of preliminary 'ming cavities SII- 5| preferably arranged inmediate the ends of the les equally spaced therefrom a pair of iinal ,'mng cavities comprising recesses 52-53.

le pairs of cavities last mentioned are of the me general shape and perform the same funclns. A guide 54 is formed on opposite sides the pair of cavities 50-5I constituting the iishing section for the purpose of guiding the inks down into said cavities and imparting a rved form thereto to curl them around the lgers 44-45. This gives a second preliminary ape to each of the blanks by the action of a eliminary forming section 55 on a punch 56 pported and actuated by the same punch hold.- as is the punch or plunger 34. The shape each of the blanks is now nearly completed ld requires only a nal setting to complete the rm. This is elected by nishing sections 51 L the punch 56, said finishing sections being cated on opposite sides of the forming section i and operating alternately on blanks supported i the two sets of forming ngers 44-45, the iished forming being effected by one section of the punch on one of the sets 44-45 of Le forming fingers 'while the next preceding irm is being given on the other side on said rming ngers. That is, in a single downward .ovement of the'punch holder 25 a blank 26 cut by the punch 24 from the strip 23, a blank partially formed to shape by the punch 34 1 the forming die 28, another preliminary shape elected by action of the forming section 55 E the punch 56 on one of the pairs of ngers l and and a final and setting form producig the finished blank 83 (see Fig. 4) is given y one of the nishng sections 51 of the punch B on the other pair of said forming fingers I-45, it being noted that when this finishing peration is performed on one of the sets of arming fingers 44-45 the next preceding step i taking place on the other of said sets. The armer die 4| has a preliminary vforming section 8 cooperating with the forming section 55 of iently supported slide base 41 seated on springs 62 mounted on guide pins 63 for guiding the -movements of the base 41, as shown in Fig. 6

die and on opposite of the drawings, said pins projecting upwardly from the die holder 8. Reciprocating sliding movement is imparted to the slide 46 by means of a stud 64 projecting from the side of the slide with a slide reciprocating rod 65 pivotally attached to said stud at one end and its opposite end bearing a. roller located in a cam groove in a slide reciprocating cam 66, the rod having a slot through which a pin 61 from the cam 66 projects in a manner common to connections of this type. The cam 66 is secured to a shaft 68 mounted'in a bearing 68 projecting upwardly from the die holder 8 and having a gear 18 meshing with a pinion 1| secured to the cam shaft 9, as shown in Fig. l f the drawings, the gears and pinions being timed to impart proper reciprocating movement to the slide, that is, to locate the forming fingers in their extreme positions for operation of' the punches upon the blanks on the ngers when such punches descend for such operation. Y

The forming fingers with the blanks partially formed thereon are nally located in the depressions in the die 4| by means of plungers 12 extending from within sockets 13 projecting downwardly from the punch holder 25, as shown in Figs. 4 and l5 of the drawings. These plungers are spring seated within the sockets and as the punch holder moves down the ends of the plungers strike the upper surface of the slide supporting base 46 and push it downward against the upper side of the die holder 8 and against the tension of the springs 62, there being four of the plungers, two located in each end of the slide supporting base 46, the four springs against which the plungers are seated being strong enough to resist the tension of the two springs 62 .and therefore sufficient to compress the` latter. This permits continuation of downward movement of the punch 56 to finish its operation after the iingers with the blanks thereon are seated in the recesses in the die 4|.

After the blanks are finally formed upon the fingers as hereinbefore described they are ejected from said fingers by means of ejectors 14 slidably mounted in the supporting slide 46 and operating against the blanks intermediate their ends to push them olf from the pins and into chutes 15 along which they are moved by contact with the succeeding blanks to a point of discharge downwardly through the die holder 8, when this manner of discharge is employed as shown in Fig. 4 of the drawings. A forked finger 16 projects upwardly from each slide in position to receive between the branches ejector actuating pins 11 extending toward each other from the ends of ejector actuating arms 18 secured to and projecting downwardly from an ejector actuating shaft 18 mounted in bearings on the upper ends of standards projecting upwardly from the die holder 8 at opposite ends of the slide base 41, as shown in Fig. 5 of the drawings. A rocking motion is imparted to the shaft by means of a shaft actuating arm 8| extending downwardly from the shaft and having a roller at its free end engaged in a groove in an ejector operating cam 82 supported on the main shaft 8, as shown in Fig. 3 of the drawings, the cam being shaped to impart an ejecting movement to the electors immediately following the completion of the formation of the blanks. As shown in Fig. the forked fingers 16 on the two electors are alternately engaged with an actuator pin 11 as the supporting slide 46 is moved from side to side.

From the foregoing description embodying a progressive explanation of the operation it will be seen on referring to Fig. 9 that the blanks 26 successively cut from the blank strip 23 are moved` from the position a by operation of thefeeding fingers 20 into the position b where they are given a preliminary form by means of the punch 34 `acting-in connection with the forming die 28. From the position b the partially formed blanks are moved by the pusher rods 43 into position c and on to a pair of forming ngers 44-45. In this position the forming punch 56 acting in connectinnwith the die 4| imparts a further form to the blanks approximating the finished form. From position c the pins with the blanks thereon are moved to one of the positions d at one side of the position c where the final formation of the blanks takes place and from which they are ejected as hereinbefore described, it 'being noted that the operations at the two positions d take place alternately, that is, the succeeding blanks are moved alternately first from the position c to one position d and then to the other position d.

It will be noted that as shown in Figs. 4, 5 and 8 the plungers 12 in their raised positions are spaced from the slide support 4l so that downward movement of the punch 56 will encounter the blanks on the fingers 45 before downward movement of the slide support 4l begins. This will cause the opposite edges of the blank to contact the guides. 54 and be certainly curled under the forming fingers before downward movement of such ngers begins.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodimentA thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by4 other means and applied to uses other than those above set out. y
