Figure. 8 is a plan view of the upper body Referring, nowto. the: drawings, 1 isthe plunger or rainwof a, punch press and 2 and 3 respectively are cooperatingetool receiving bodiesof a holder at embodying my invention. As shown, the bodies 2 and 3 are arranged in superposed relation and are secured by bolts 4 to the ram 1 of the punch press. The upper body 2 has a singlevertic'al bore 5. that extendsv therethrough and is closed at its upper'end' by a hardened backing plate 6 interposedbetw'een the body 2 and ram 1, while the lower body 31 hasa vertical bore '7 in alignment with the bore. and has a series. of' vertical bores 8 arranged in a circle about said bore 7,. preferably concentrically with respect thereto. Each of the last mentioned bores 8. extends through the lower body Band has its upper end. closed by the lower faceof the upper body. Ar ranged in another circle, preferably concentric with the bore. '7 and. the circle of holes 8', are shorter bores 9 that extend downwardly from the upper faceoi the lower body in substantially parallel, relation to. the bores 8 andlterminate short of thelower face 10 of'said body. Slots ll, substantially equal in depth. to the depth of the bores. 9 and having substantially parallel walls 12, and 13,.extendbetween and open into the bores 8 and 9,,ywhile relatively small bores 14 extend upwardly from the lower face of. the body 3to the slots 11' and are preferably parallel to the bores 8. Likewise-the upper body 2 has a bore 15 that extends downwardly from-the upper face ofithe'body in substantially parallelrelation to the'bore' 5-and: terminates short of. the'lower face of thefbody. A' slot 1'6substantially equal infdepth to the depth of the-bore l5 and having substantially parallel-walls 17 and 18"respectively extends between 'and'opens into the bores 5'and 15, while a relatively small bore 19-extends-up wardly from the lower faceof the body 2' to'the slot lfi. As shown, thisbore 19 is parallel to the bore:.51 and is in alignment with a bore 20 of similar diameter. extending vertically throughthe lower body 3...

Located within the bores 9 and15 are leverss22, coil springs 2V3-and sleeves-or bushings 24 similar to parts 14-, 2 0 and21 respectively illustrated in my pendingapplication aforesaid and constituting the means for'retaining. the shanks 26 of punches withinthe bores 5, 7 and. 8 respectively inthe bodies. As shown, thelevers 22. have spherical lower ends 27 journaled in rounded portions 28 and 29 respectively of the bodies 2' and 3'at the lowerends ofithe bores 9'and"'15,, extend diagonal- 1y through the, slots'll and 16 respectively and havearcuate upper ends for engagement with the punch. shanks. 25. The, spring bushings. 24 are fixed within the bores 9 and l5-respectively sons to hold-the spherical ends 27 of the levers within the rounded portions28and 29 respecthe arcuate ends 30 of the levers in the lower body 3 when the shanks 42 are inserted into the bores 8, while the shank 45 of the long punch 41 is provided adjacent its upper end with an arcuate slot or groove 46 that is engaged by the arcuate end 30 of the lever in the upper body 2 when said shank 45 is inserted into the aligned bores 7 and 5. In this connection it willbe noted that the levers have a propping action and hold the upper ends of the punch shanks 42 and 45 respectively against the backing plates 2 and 6. Any suitable means such as anextractor pin 4'7 may be inserted inio the bore 14 or into the aligned bores 19 and 20 to push the levers upwardly against the tension of the springs to release the punches so'that they may be withdrawn from the holder. Thus punches may be readily inserted'in or withdrawn from the holder wiihouthaving to take it apart or separate it from the ram. v

In Figures 6 to 8 inclusive I have illustrated a slight modification wherein the'bodies 50 and 51 respectively are rectangular infshape and each 5 contains a plurality of punch shanks. As shown,

the upper body 51 has four bores 52 arranged in a row, while the lower body 50 has four bores 53 arranged in registration with the bores 52 in the upper body and is provided upon opposite sides of said bores 53 with two rows of bores 54. The spring pressed levers 55 correspond to the levers 22 and are located in bores 56' and 57 respectively at the sides'of the bores 52 and 54 for retaining engagement with the tool shanks 58 and 59 respectively. Likewise bores 60'are provided in the lower body 50 in alignment with the bores 5'7 for receiving the extractor pins (not shown) and registering extractor pin bores 61' and 62 respectively ar'e'provided in the bodies '50 and 51 in alignment with the bores 56.

While it is believed that from thef'foregoing description the nature and advantages of the invention will be readily apparent, I desire, to have it understood that I do not limit myself to what is herein shown and described and that-such changes may beresorted to when desired as fall within the scope ofwhat is claimed. v
