Description

July 20, 1954 w. P. RANDOLPH, SR
STAMPING DIE HOLDER Filed Dec. 2, 1952 Patented July 20, 1954 UNITED STATS aegis OFFICE 4 Claims.
The present invention relates to a holder tool which, although not limited thereto, is especially suitable for use to hold a single stamping die in marking position without the hazard of injury to the ha and fingers of the user.
It is an object of this invention to provide a holder tool is simple and rugged in corn struction and inexpensive to manufacture.
it is a further object of the invention to provide a holder tool wherein a single stamping die may be quickly easily fitted and automatically retained.
Another object of the invention is to provide a holder tool whereby a single stamping die may be held marking position to receive an impact with a minimum of danger of injury to the user.
These other objects will become more apparent after referring to the following specification and attached drawings, in which:
Figure l is a plan view;
Figure 2 a longitudinal sectional elevational View taken on line II-II of Figure 1;
Figure 3 is a perspective View showing the notched end of the tube member of my invention; and
Figure 4 is a perspective view of the die holder element of my invention.
Referring more particularly to the drawings, reference numeral 2 indicates generally the holder tool of my invention. The main body of the tool consists of an elongated tubular housing :3 having a pair of opposed V notches 6 and a pair of opposed rectangular slots 8 in one end thereof. An end portion H] of the housing 4 remote from the notched and slotted end is provided with an enlarged inside diameter recess portion 9. The junction between the recess portion of the tube and the remainder thereof forms an annular shoulder l2.
A rod i l having a die holder it integral with one end and a threaded portion i8 is slidably disposed within the housing i. The die holder 16 projects from the notched and slotted end of the tube while the threaded portion i3 projects from the recess 9.
An inner threaded jam washer 20 is threaded on the threaded portion of the rod it Within the recess portion of the housing 4 spaced from the annular shoulder l2. A cap disc 22 is affixed by threading or otherwise to the projecting end of the threaded portion IS.
A helical compression spring 2% is circumferentially disposed around the rod M within the ing against the annular shoulder I2 and its other 2 end bearing against the jam washer 28. The spring as normally'urges the rod l outwardly of the recess end of the housing.
If desired, the tube may be provided with a uniform inside diameter and the helical spring may be disposed around the projecting end of the rod with one end bearing against the end 01 the tubular housing and its other end bearing against the jam washer.
The die holder it, which is substantially rectangular in shape, is dimensioned to fit slidingly into the slots 5?. The width of the die holder is greater than the diameter of the housing l so that the spring biased movement of the rod is limited by abutment of the die holder against the rearward edges of the slots The die holder is provided with a hole 25 there through which extends normal to the longitudinal axis of the rod H3 for receiving a stamping die 23. The hole 25 is formed with a rectangular periphery to conform with the contour of the stamping die body. The hole is so turned that the apex 3% formed at the junction of two of its sides coincides with the apex of V notches 5 e held rigid by the V notches 5 when the die holder is in retracted position as shown in Figures 1 and 2.
Although I have shown notches 5 as having a V shape and the hole 28 turned as shown in Figures 1 and 4, it will be noted that the notches 6 may be rectangular in shape and the hole 28 turned accordingly if desired.
A wing nut 32 may be threaded or otherwise attached around the outer circumference of the housing 4 spaced a short distance from the end thereof out of which the threaded portion of the rod I l projects to facilitate operation of the holder tool as will become apparent.
A portion 3 3 of the outer surface of the tube t intermediate its ends may be roughened or knurled so that the tool may be grasped securely when being used.
In operation, the user of the tool applies manual force on the cap disc 22 with the palm of his hand while en aging wing nut 32 with his fingers. This causes spring 25 to be compressed and die holder it to be projected outwardly beyond the notched and slotted end of the housing t where by the hole 25 is cleared so that the stamping die 26 may be inserted therein. After the stamping die is positioned in the hole, pressure on the cap disc 22 is released and the spring 24 bearing against the jam washer 20 moves the rod causing the die holder to retract and hold the stamping die in rigid position within the V notches. Then grasping the holder tool around the knurled portion 34, the user positions the stamping end of the stamping die on the surface to be marked. The mark is then stamped on the surface by applying an impact blow to the head of the stamping die in the conventional manner with a hammer or other suitable means. To change stamping dies, manual force is again applied to the cap disc 22, in the manner described above, to compress spring 24 and project the die holder outwardly of the notched and slotted end of the housing. This relieves the pressure from the stamping die, permitting its ready removal and replacement.
It will be seen that the holder tool of my invention permits use of a stamping die in the usual manner without the necessity of exposing the fingers and hands of the user to injury by the striking hammer. My holder tool also minimizes the hazard of burns when it is utilized for stamping hot objects such as hot rolled steel bars, billets, shapes, etc.
While one embodiment of my invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
I claim:
1. Apparatus for holding a single stamp die having an elongated body portion which comprises an open end tubular housing having a first pair of opposed slots and a second pair of opposed slots in one end thereof, said second pair of slots being shaped to engage the body of said die, a rod slidingly telescoped within said housing with its forward end projecting from the slotted end of said housing, a die holder integral with the forward end of said rod, the width of said die holder being greater than the diameter of said housing, said die holder being dimensioned otherwise to fit slidingly in said first pair of slots, said die holder having a hole therethrough normal to the longitudinal axis of said rod for receiving said stamp die, said hole coinciding with said second pair of slots when said die holder is engaged in said first pair of slots,
and means for urging said rod inwardly of said housing in the direction away from its slotted end.
2. Apparatus for holding a single stamp die as defined by claim 1 characterized by the end of said rod opposite said die holder projecting outwardly of said housing, said rod-urging means including a helical compression spring disposed on said rod adjacent said last named projecting end, and bearing means for one end of said spring on the rod intermediate its last named projecting end and the spring, and the other end of said spring bearing against said housing whereby outward motion of the rod relative to the housing is effected.
3. Apparatus for holding a single stamp die as defined by claim 1 characterized by the end of said rod opposite said die holder projecting outwardly of said housing, said housing having an enlarged inside diameter recess portion adjacent the end thereof opposite said slotted end and said rod-urging means including bearing means on the rod adjacent the last named projecting end thereof, and a helical compression spring mounted around the portion of said rod disposed substantially within the recess portion of said housing with one end abutting against said bearing means and the other end bearing against the inner end of said recess.
4. Apparatus for holding a single stamp die as defined by claim 3 characterized by a cap ailixed on said last named projecting end of said rod, and a pair of opposed handle members projecting from the outer surface of said housing intermediate the ends thereof.
