DIE-HOLDER.

To all whom it may concern Be it known that I, J osnrrr LUCAS, a citizen of the United States of America, residing at Kulpmont, in the county of Northumberland and State of Pennsylvania, have invented certain new and useful Improvements in DieHolders, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a die holder and has for its principal object the production of a die holder which is adapted to be used in connection with anvils, particularly in the blacksmith art, and which is so constructed as to efliciently retain a piece of heated metal which is being shaped, without the necessity of secondary securing means.

Another object of this invention is the production of a die holder wherein a hollow post is adapted to receive a pair of dies in such a manner as to allow a piece of metal to extend transversely through the post and between the ends of the dies so.as to allow the metal to be shaped as the upper die is hammered or pounded upon.

With these and other objects in View this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a side elevation of the die holder as constructed'in accordance with this invention, illustrating the same in a position for use as mounted upon an anvil. Fig. 2 is a vertical section taken on the line 22 of Fig. 1. Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1. Fig. 4 is a detail perspective view of the primary die.

Referring to the accompanying drawing by numerals it will be seenthatthis die holder is adapted to be used in connection with an ordinary anvil 1 having a squared opening 2 formed therein.

The post 3 is preferably rectangular in cross-section so as to hold the dies when mounted therein against torsional or rotary movement. This post 3 has the enlarged annular base 4 formed integral upon its lower end, as clearly disclosed in Fig. 3, so as to allow this base to rest evenly upon the upper surface of the anvil 1, thereby assisting in retaining the post 3 in its correct vertical position when in use. This post 3 is provided with a plurality of openings 5 formed in alinement with each other, and the upper Specification of Letters Patent. I Patented Sept. 12, 1916. Application filed February 19, 1916.

Serial No. 79,371.

lower edges of the post 3 communicating wciti the openings 5 are rounded as indicated a The auxiliary die 7 is squared so as to con form in contour to the inner portions of the post 3, thereby firmly and snugly fitting within the post when in use. The lower end 8 of this primary die 7 is squared in crosssection, although it is considerably smaller than the top portion of the die 7 whereby the lower end 8 may fit snugly within the squared opening 2 formed in the anvil 1, while the shoulder 9 formed by the construction of the end 8 will limit the downward movement of the primary die 7, since this shoulder will rest upon the upper surface of the anvil 1, as shown in Fig. 2.

The primary die 10 is also square in crosssection and has a flat upper end 11 so as to provide an even surface which may be pounded or hammered upon. Both of the dies 7 and 10 as herein disclosed have semicircular notches 12 formed therein so that these notches 12 will register when the dies 7 and 10 are in operation so that when a piece of metal is extended therethrough and the die 10 is hammered upon the metal may be formd to present a round structure.

When this die holder is in use the primary die 7 is first placed upon the anvil 1 so as to allow the reduced end 8 thereof to fit within the opening 2 formed in the anvil. The post 3 is then fitted over the primary die 7 so as to allow the upper end of this die 7 to extend into registry with the openings 5 formed in the post 3. The auxiliary die 10 is then placed upon the upper portion of the post 3, as shown clearly in Figs. 1 and 2, so as to rest upon the upper portion of the primary die 7. The blacksmith or other artisan may then raise the auxiliary die 10 sufficiently to pass a piece of heated metal between the abutting ends of the primary and auxiliary dies, and then by hammering or pounding upon the upper end 11 of the auxiliary die 10 he may make any desired form out of the metal, according to the shape of the abutting ends of thedie's. Thus, it will be seen that it will not be necessary to employ an assistant to hold the metal which is being hammered upon or which is being constructed to form a desired shape for the person using this die holder may hammer upon the auxiliary die 10 with a sledge held in one hand and may easily turn the metal which is being hammered upon to difierent positions so as to cause the hammering upon the auxiliary die to shape the metal as desired.

It is, of course, obvious that it is not intended to limit the construction of the abutting ends of the primary and auxiliary dies to the specific form herein disclosed, for they may have flat abutting ends, or rounded abutting ends, or one end may be flat and the other abutting end pointed for punching holes in strips of metal without departing from the spirit of this invention. As above set forth, the principal object of this invention is the production of a die holder which may be mounted upon the anvil to form the metal by presenting different shapes and forms and consequently, the formation of the abutting ends of the dies is not material.

From the foregoing description it will be seen that a very simple and efiicient die holder has been produced which is so constructed as to firmly fit upon the upper portions of an anvil when in operation, while the construction of the alined openings of the post will permit pieces of metal to be directed therethrough between the abutting ends of the dies. Furthermore, it will be seen that after the metal has been passed between the abutting ends of the dies it is not positively necessary to hold the same, for the metal will be retained by the abutting ends of the dies in a position to receive the force of the hammering or pounding upon the auxiliary die.

lVhat is claimed is:

1. A die holder of the class described comprising a hollow post, said post being adapted to fit upon the upper portion of an anvil, a primary die partially fitting within said post and also being adapted to engage the anvil for holding the post in a set position upon the anvil, an auxiliary die fitting within the upper end of said post, whereby said dies will abut against each other, said post being provided with alined side openings formed in registry with said dies, whereby a piece of metal may be passed through said openings and interposed between the abutting ends of the dies so as to allow the metal to be pounded upon to form definite shapes.

2. A die holder of the class described comprising a hollow post, said post being rectangular in cross-section, and an enlarged base formed upon the lower end of said post,

said post being adapted to rest upon the upper surface of an anvil, said post being further provided with alined openings, a primary die fitting within the lower portion of said post and being adapted to extend into the anvil for holding said post in a set position upon the anvil, an auxiliary die extending into the upper end of said post, whereby the lower end of the auxiliary die will rest upon the upper end of the primary die, thereby allowing a piece of metal or a metal rod to be passed through the openings formed in said post and be interposed be tween the abutting ends of said dies so that when pounding or hammering pressure is brought to bear upon the auxiliary die the force will be imparted to the metal extending between the ends of the dies so as to al low the metal to be hammered to assume a definite shape, said dies fitting snugly within said post, whereby said post will hold said dies against rotation.

3. A device of the class described comprising an elongated hollow post, said post being substantially rectangular in cross section, and having an enlarged base formed upon the lower end thereof, said base being adapted to fit upon the upper surface of an anvil for assisting in retaining the post in a vertical position, said post being provided with a pair of alined side openings, said openings having beveled edges, thereby forming guides for said openings, a primary die fitting within the lower portion of said post, said primary die being rectangular in cross section so as to fit snugly within said post, said primary die being provided with a squared lower end, whereby the lower end may fit within the opening formed in the anvil, whereby the post and die will be held in a set position, an auxiliary die fitting within the upper portion of said post, said auxil iary die being provided with a fiat upper end so as to facilitate the hammering or pounding thereon, said post being adapted to allow a piece of metal or a meta-l rod to be passed through the alined openings and insignature.
