The. springBfl is; carried somewhat freely on an adjust.- able. stud 35,.that is carried by a frame member- 36. as will be seen Icy-reference to Figure-5. Slide rails 31. and 38- fastened toparts of the-base member -4 in any" satisfactory manner as hyfcap. screws 39, have at: the stock enteringend-of the structure, members and: M each having zaslot 42 to receive'a locking stud that engages a'clamp. ing washerto hold the members-Mandi I; invadjusted positi0n.= On theinnerends of each member 40 and 4|. is mountedadouble row ballvbesring. Thesef bearings" engage the edges; :o'i: ithe v 3 stock and thereby guide and assist in passing the stock through the apparatus.
Adjacent the members 40 and 4| is a brace rod 45 fastened to the extremities of the slide rails 31 and 38 as by cap screws 46. The slide rails 31 and 38 have inwardly projecting ledges 41 and 4 8 which engage co-operative portions of the slide 23 over fiat bearing surfaces of considerable area.
A very;impojrtant feature of this invention is the use of a'pair of laterally spaced gibs 49 and 50 located in opposite parts of the base member 4 relatively close to the edges thereof so as to be approximately below the sides ;of the slide which carry the feed lock. These gibs are pressed against the bottom of the feed slide by similar springs 5| at opposite ends of the gibs, the tension of the springs is controlled by screws 52. Preferably the gibs 49 and 50 are made of material different from the base of the slide, such' as bronze. These gibs apply to the slidecontinuous and uniform braking-action and provides automatic compensation for wear at the areas 41- and'48 ;and thereby prevents its slipping and insures accurate feeding of the stock at all times. I
The slidehas a centrally located boss 53 which is adapted to engage adjustable stop screws 54 and 55 which are setto co-operate with springs 25 and, 26 that also act to take up motion of the press armconnected to the arm of lever 9. This means that'the press may be operated with a crank arm instead of a cam which is usually used to provide a dwell while the press punch is going through the stock. The springs 25 and 26 also provide a safety feature in being able to take care of errors in setting up the apparatus. An adjustable stop 56 is carried by the slide to limit the movement of the feed lock 24 during the return movement of the slide and also to adjust the lock 24 to take care of stocks of different thickness. Lock 3| is likewise-adjust able to'take care of such stocks. l
In Figures 7 and 8 I have shown a modified form of feedlock 51 wherein the stock engaging end is provided with a plurality adjustable set screws 58 which are adapted to engage stock, having a high finish, at points which will be on the scrap and not on the punched out part. A similar construction should be used on the lock corresponding to 3|. Other variations in the details may be utilized without departing from the scope of the appended claims. What I claim is:
