For adjustably sustaining the stack of blanks tion particularly to support 51, a description a .the combination of a hopper for holding a stack of fastener blanks, a table for receive blank and push out from` the, upper face B so that only one at a time'will be removed by blades 9CL and 9b as those blades move forwardly under said stack, opposite blank supports 50,51 are provided. Directing attenof which will suffice for both, said' support comprises rail 51EL Ylying below presser foot 45 and in parallelism therewith.Al Said rail is carriedv by arm 51b extending at right angles' therefrom, and said larmis .pivotally mountedl at Y52 on the front of hopper 8.V

The outer end of arm 51b is adjustable up and'down by means of screw53, and spring 5.4 offers a yielding resistance to said screw and arm. By this means rail 51may be For locating punching station, adjustable stops 55,56 are provided.

' The operationV of my improved machine' is as follows: A supply of fastener blanks B having beeninserted in hopper 8, cam shaft v6 is started rotating-in clockwise direction,

Fig. 1. Assuming that slide 9 and blades 9a,

V9b are in the position o f Fig. 1, the lowermost blank in hopper 8 will lie with its long Varms in notchesV 40, 41 ofsaid blades, re-v spectively,'blank support rails 50a, 51a'sustaining said blank at ja height which will present the lupper face Iof thev blank'just above the plane of the upper faces of bladesv 9a, 9b. Then as said blades move forwardly tothe right, Figs. 1 and 2, they will/carry said Ablank along under presser feet 44, 45 to the punching station, over punches 25, 25, Fig. 4. Die block 17 then `descends into engagement with the upper face ofthe blank, holding thatk blank securely against table 10. Punches 25, 25 then ascend, penetrate said thereof Vthe usual projecting prongs. Die block 17 then retires upwardly, said prongs being stripped therefrom by presserfeet 44,

45, `and punches `25, 25 follow said die block a distance sui'licient to lift the blank out of engagement with notches 40,41 ofv blades 9a, 9b, thereby lifting presser feet 44, slightly, Fig. 4,`the friction of said prongs yagainst said punches being sui'licient to maintain the relation of the fastener and punches against the weak presser lfoot springs 48, 49.

While said punched blank is thus held above blades 9a, 9bsaid blades retire to the left,

back to the position of'F ig. l toreceive'an- Y other blank in their notches. Punches 25, 25

.then retire downwardly and the blank rests upon table 10, ready to be discharged vinto ports under said stack of blanks, and means for adjusting said supports for lowering said blanks.
