3 Claims. (Cl. 279-777) The invention relates to improvements in which L shaped release pin 5 can be put in place. punch locking device for quick release punch re- Release pin hole 13 is enlarged at end opposite tainers 4which allows the removal of punches pocket 11 to provide a pocket 14 for spring 6. which have been dulled or broken, and the ob- Locking block 3 is a sliding lit in locking block x5 jects of the improvements are; pocket 11 and has locking block hole 16, which 55 First, it affords the absolute control of all parts locking block hole 16 is a slip lit for the short of the said locking device, that is, there are no leg of the L shaped release pin 5, said release loose or oating details which interfere with the pin 5 controlling the movement of the locking removal or insertion of the punch, block 3. Locking block 3 is made irregular in Second, it affords facilities for the operator to outline, so that a rotating motion of the locking 35 make the change of punches without the aid of block 3 is obtained by reason of the reciprocating any tools or equipment, and motion of the release pin 5 and locking blocks Third, it enables the diemaker in aligning the relative position to guide 4. A spring 6 iS plaoed punch and die following construction to manip- 0n release pin 5 and in Spring pooket 14 and re- '115 ulate the punches so as to inspect them in relatained by means of a release button 7 which is 79 tion to holes in the die without the removal of the rivetted on to release pin 5.

The release pin exerted on release pin button 7 by the die maker hole 13 also in pad 1 is parallel to punch hole 10 after the test for alignment of the punches in and parallel to the side of pocket 11 and extends the die. It will be noticed that this position is through pad 1. In pad 1 stock is cut away between accomplished by swinging the locking end of the upper end of release pin hole 13 and locking block locking block 3 away from the punch 8.
55 pocket 11 thus forming release pin slot 15 through I am aware that prior to my invention punch; 11
locking devices have been made with locking mechanisms for the release of punches. I therefore do not claim such a combination broadly; but I claim:
1. In a device of the class described, a pad bored to receive a tool shank, the wall of said bore being recessed, a tool-locking block having vertical and rotary movement in said recess, guide means inclined towards the receiving end of the bore of said pad and engaging one end of said block, further guide means inclined towards the .bore of said pad and engaging one end of said block, a thrust member inclined towards the other end of said bore and engaging the opposite end of said block, and manually operable means for effecting verticalmovement of said block in said recess whereby positive rotation of said block in one or other direction is guided by said guide means and said thrust member.
3. In a device of the class described, a pad bored to receive a tool shank, the wall of said bore being laterally recessed to provide an inclined surface directed towards the receiving end of said bore, a manually operable vertically movable plunger entering said recess, a tool-locking block in said recess fulcrummed intermediate of its length on the inner end of said member, said block being swingable to a position projecting into thebore of said pad in one position of said plunger and swingable to a latched position within said recess in the other position of said plunger, resilient means tending to move said plunger to its rst-mentioned position, and a thrust member engaging the inner end of said block to resist pressure of a tool thereon when said block is in its tool-locking position.
