DIE FOR MAKING AXES.

SPICIFICATION forming part of Letters Patent No. 402,935, dated May '7, 1889.

Application filed February 19, 1889- Serial No. 300,433. (No model.)

To aZZ whom, it may concern.-

Be it known that I, J AMES P. KELLY, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Dies for Making Axes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in dies for forming axes and analogous implements; and it consists of a two-part die, each part having a depression corresponding to the general shape and contour of the ax which it is designed to make, the lower part or half being formed with a raised portion or anvil at each end, and the upper part or half with corresponding recesses, and both dies with recesses to accommodate or receive an eye-pin or mandrel used in forming the eye of the ax, as will hereinafter in detail be described.

In order that those skilled in the art to which my invention pertains may know how to make and use the same, I will proceed to describe the details of construction and the effects by use of my improved dies, referring by letters to the accompanying drawings, in which Figure 1 is a perspective view of the two parts of the die in an open condition. Fig. 2 is a longitudinal section of the dies in their closed condition, and Fig. 3 is a transverse section taken at the lineac a: of Fig. 2. Figs. 2 and 3 are made on a decreased scale.

Similar letters indicate like parts in the several figures.

A A represent the two halves or parts of a die designed to make an ax invented by W. 0. Kelly, and being manufactured by the Kelly Axe Manufacturing Company, of Louisville, Kentucky, and I wish it to be here understood that I make no claim to the design ormechanical features of construction of such ax. Each half A and A is formed with a cavity or depression in the face corresponding to the general design or outline of the ax to be formed.

a a are portions extending above the horizontal plane of the portion 1), and the former are designed to make What are known in the Kelly ax as the recesses in the blade to decrease the bite of the wood, while the portion 1) forms that part of the blade located between and below the recesses referred to. At the blade end of the cavity in the lower die, A, is formed an anvil, 13, extending above the face or horizontal plane of the ,die sufficiently' high to form a distinct bridge or abutment against the cutting or extreme edge of the ax to be formed, and at the opposite end of said die A is formed another anvil, B, equal in its height to the thickness of the head of the ax.

In the die A are formed at each end recesses O and 0, corresponding with the anvils B and B, respectively, so that when the two dies A A are brought into the proper relation to act upon the blank and form the ax the anvils B B prevent any undue elongation of the ax, and the head is formed against the anvil B in a smooth and finished condition without the usual fin resulting from the use of the ordinary counterpart dies, which have usually proved unsuccessful. In the face of each of the dies, and extending from the outside boundary of the raised portions a, are formed recesses or cavities c, to provide a space for the excess of metal forced out laterally in fin-like form from the blank dur ing compression, and which is subsequently sawed or out off.

To provide for the eye-pin or mandrel used in forming the eye of the ax, each die is formed with a cavity, d, which may extend only partially across the die, as shown in solid lines, or entirely across, as shown by the dotted lines, though in practice I prefer the latter construction.

The general design or contour of the cavity in each half of the die, as before stated, corresponds with the general design or shape of the ax to be made; but I prefer that at that point where the steel bit is located the dies should be so increased in the depth of cavity that the ax shall not be compressed or brought to its exactfinal thickness, in order that it may be subsequently refined at that point by hammering; but I do not wish to confine myself in this particular, as the blank may be compressed to its final shape.

I desire it to be especially understood that whatI consider the chief advantage in my dies over those that have heretofore been. made is that they are in no sense counterparts of each other, but, on the contrary, that while each half is formed with a cavity corresponding generally to the shape or contour of the ax to be made there is provided in one an anvil and in the other a corresponding cavity at each end, which not only prevent undue elongation of the blank and determine the exact length of the ax, but also, in the case of the anvil B, form the face of the ax in its finished form without a fin or subsequent treatment; and it will also be understood that by providing the cavities c for the excess of metal, and entirely surrounding the cavities of all kinds by the body or the die-block, my dies are constituted closed dies in contradistinction to open dies, and consequently they may be brought together in such manner as to produce an ax in its final shape or proportions in one operation, with the sole exception of removing the excess of metal, which is forced out laterally into the cavities c.

It will be understood, of course, that I do not confine myself to the exact design of the cavities shown, but that I have only taken this as an example to illustrate my invention, and because I am at present engaged in manufacturing what is known as the Kelly ax, it being understood that any other form of ax can be made with equal facility, and it will also be apparent that hatchets and similar tools can also be made economically and expeditiously by dies embodying the feature of my invention.

\Vhat I claim as new, and desire to secure by Letters Patent, 1s-

1. A two-part die for forming axes and the like, each part provided with a cavity corresponding with the general design of the tool to be made, and one part provided with the anvils B B and the other with cavities Q U, substantially as an d for the purposes set forth.

2. A two-part die for forming axes and the like, each part provided with a cavity corre spending with the general design of the tool to be made, and provided also with recesses c to receive the excess of metal, substantially as hereinbefore set forth.

3. A two-part die for forming axes and the like, each part provided with a cavity corresponding with the general design of the tool to be made, and with recesses c to receive the excess of metal, and cavities (Z for the eyepin, one part being also formed with anvils 1-3 B, and the other part with corresponding cavities, O C, substantially as and for the purposes set forth.

4. A two-part die for forming axes and the like, provided with a cavity corresponding with the general design of the tool to be made, and with recesses c, said cavity and recesses being entirely surrounded by the stock of the die, substantially as shown, whereby a closed die is formed, as hereinbefore described.

In testimony whereof I affix my signature in presence of two witnesses.
