INCORPORATED, 0F DETRQIT, MICHIGAN, A CORPORATION OF MICHIGAN T0013 HOLDER I Application filed February 18, 195 31. Serial No. 516,192.
clined side 18 of the plunger. The shank 3' This invention relates generally to tool holders, especially punch and die retainers, and consists of certain novel features of construction, combinations and arrangements 'of parts, that will Lehereinafter more fully described aud particularly pointed out in the appended claims.
In the accompanying drawing Figure l is a vertical sectional view through a retainer and hardened backing plate assembly embodying my invention and showing the same applied to the base casting of a punch press;
Figure 2 is a view similar to Figure 1 after the punch has been lowered in the retainer;
Figure 3 is a top plan view of the retainer;
Figure 4 is a bottom plan view of the retainer;
Figure 5 is a sectional view taken on the line 55 of Figure 1;
Figure 6 is a detail view of the punch;
Figure 7 is a detail view of the plunger.
Referring now to the drawing, 1 is a base casting of a punch press; 2 is a punch having a shank 3 and a work engaging head 4; 5 is a punch retainer bolted to the casting 1 and having a vertical bore 6 receiving the shank 8 of the punch; 7 is a hardened backing plate for the punch shank closing the upper end of the bore 6 and constituting a seat for the upper end of the tool shank 3; 8 is a plunger movable transversely of the retainer 5 to hold the shank 3 in the bore 6; 9 is a guidep'in extending through the plunger 8 and engag ing aligned horizontal grooves 10 andll respectively in the retainer 5; 12 is a coil spring maintaining the plunger 8 in projected position to engage the shank 3, and 13 is a screw 1 adjustable in the retainer to maintain the plunger 8 in firm engagement with the punch shank 3. As shown, the plunger 8 is hexagonal in shape and is slidable in a plane at right angles to the punch shank. Preferably thescrew 13 is adjustable in a plane parallel to the bolt 6 receiving the punch shank andjhas a tapered upper end 14 that engages the innermost lower inclined side 15 of the plunger 8 while the spring 12 is received in a socket 16 in a plug 17 having a press fit within the retainer and engages the innermost upper in- I Russet;
of thepunch has a V shaped recess 19 that receives the outermost upper and lower inclined sides 20 and 21 respectively of the plunger, and the arrangement is such that the pressure exerted by the bevelled end 14 by the screw against the inclined side-l5 of the plunger is transmitted to the inclined wall 22 of the recess 19 in the punch shank so that the upper end .23 of the punch shank is cammed firmly against the backing plate 7. In other words, the adjustment of the screw 13 not only actu'ates the plunger 8 transverse- 1y ,of the retainer into the recess 19 in the punch shank so that the punch will be held against withdrawal from the bore 6 but in' addition moves the punch bodily upwardly against the backing plate so that all play or lost motion between the parts is effectively taken up and a firm connection is established.
When the screw13 is loosened the punch 4 may be withdrawn from the bore 6 as a pull on the punch will cause the inclined wall 22 of the recess 19 to cam the plunger 8 back against the tension of the spring 12. However, as soon as the punch is withdrawn the spring 12 will again force the plunger 8 forwardly so that the forward end thereof projects into the bore. Consequently when the same or another punch is inserted into the bore 6 the plunger 8 will snap into the recess 19 and will holdthe punch in the retainer. The screw 13 may then be tightened to establish the firm connection above referred to.
While it is believed that from the 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 describedand that such changes may be resorted to when desired as fall within the scope of what is claimed.
What I claim as my invention is:
1. In a tool holder, a body having a bore for receiving the shank of a tool, a seat for the shank at one end of the bore, and means for pressing the shank against said seat including a plunger movable longitudinally in the body and having a cam surface at its outer end engageable with the shank, a spring means sald plunger an constantly bearing against the plunger to maintain it in pro ected positionpand an adjustable element in the body and engageable with the plunger.
\ i. 2. In a tool holder, a body having a bore I for receiving the shank of a tool, a seat for the shank at one end of the bore, a longitudinally movable plunger in the body having a cam face for engaging and urging a tool shank against said seat and having two inclined faces at its inner end, a coil spring constantly abutting one of said inclined faces, and a manually o erable member in the body movable to and rom the other of said inclined faces.
3. In a tool holder, a body having a bore for receiving the shank of a tool, a seat for the shank at one end of the bore, a plunger movable transversely of the body into the bore fiend having means for engaging and urging a tool shank against said seat, means within the body for limiting the movement of'the plunger into the bore, and means always in engagement with the plunger and constantly urging the same toward said limiting means.
4. In a tool holder, a body havin a bore for receiving the shank of a tool an having substantially aligned guide grooves adjacent said bore, a seat for the shank at one end of the bore, and means for urging the shank substantially aligned. guide grooves extending at substantially right an les to said bore with the outer ends thereo adjacent said bore, a seat for. the shank at one end of the bore, means for urging the shank against said "seat including a. slidable member having a cam face for engagement with the tool shank, means for moving said slidable member, and means for limiting the outward movement of said plunger including a pin carried by the -'plunger and having portions within said guide grooves and engageable with the outer' ends t ereof.
6. In a tool holder, a body having a bore for receiving the shank of a tool, a seat for the shank at one end of the bore, a plunger movable in the body transversely of the bore, and means for moving a tool shank in the .bore against said seat including yieldable means constantly bearing against the plunger,
and a screw threadedly engaging the body and engageable with the plunger.
7. In a tool holder, a body having a bore for receiving the shank of a tool, a seat for the shank at the upper end of the bore, and
' means for urging the shank longitudinally of the bore toward and for holding said shank against said seat, including a spring within the body and extending toward the lower end of thebore, a reciprocating member movable by the spring into the bore and having a cam- :ning surface facing the upper end of the bore and 'engageablegwith the shank, and means associated with the body for limiting the movement of the member into the bore.
8. In a tool holder, a body having a bore for receiving the shank of a tool, a seat for the shank at one end of the bore and means for urging the shank longitudinally of the bore toward and for holding said shank against said seat, including a. screw threadedly engaging the body, a spring within the body adjacent but out of contact with the screw, and a member-movable by said spring while the screwis stationary, and being also movable by said screw.
9.

10. In a tool holder, a body having a bore for receiving the shank of a tool, a seat for the shank at one end of the bore and means for urging the shank longitudinally of the bore toward and for holding the shank against said seat, including a manually operable member in; the body, a member movable by the manually operable member into the bore, and yieldable means operable while the manually operable means is stationary for moving the last mentioned member.
11. In a tool holder, a' body having a bore for receiving the'shank of a tool, a seat for the shank at one end of the bore and means for urging the shank longitudinally of the -bore toward and for holding the shank against said seat, including a yieldable ele ment and a manuall operable element, and
a member operable y one of said elements without causin the other to move.
12. In a tool older, a body having a bore for receiving the'shankai'f a tool, a seat for the shank at one end of the bore and means for urging the shank longitudinally of the bore toward and for holding the shank against said seat, including a yieldable clecut and a manually operable element, and a member operable by either of said elements to engage the shank, one of said elements being operable to move the member without moving the other element.
