Improvements in and relating to the Construction of Dies for
Making Axes and like Tools.
I, JAMES PAUL KELLY, residing at the South West Corner of Arbegast Avenue
and 16th Street, in the City of Louisville, County of Jefferson and State of Kentucky
one of the United States of America, Manufacturer, do hereby declare the nature of
this invention and in what manner the same is to be performed, 'o be particularly
described and ascertained in and by the following statement.
My invention relates to certain new and useful improvements in dies for formning
axes and analogous implements, and 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, 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 be described in detail.
In order that those skilled in the art to which my invention pertains may know
how to make and use the saine 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
Figure 2, is a longitudinal section of the dies in their closed condition, and
Figure 3, is a transverse section taken at the line, a, z, of Figure 2.
Figures 2 and 3, are made on a decreased scale.
Similar letters indicate like parts in the several Figures of the drawings.
A, A¹, represent the two halves or parts of the die each half, A, and, A', of which
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, 6, and the
former are designed to make what is known in the Kelly Ax, as the recesses in the
blade to decrease the bite of the wood, while the portion, b, 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, B, 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, B¹, equal in its height to the thickness of the
head of the ax.
In the die, A, are formed at each end recesses, C, and, C', corresponding with the
anvils, B, and, B³, respectively, so that when the two dies, A, A¹, 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, B¹, 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 during compression, (and which is
subsequently sawed or cut off).
To provide for the eye-pin or mandrel used in forming the eye of the ax, each die
s formed with a cavity, d, which may extend only partially across the die as shown
n solid lines, or entirely across as shown by the dotted lines, though in practice, I
brefer 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

page_text: that at that point where the steel bit is located that the dies should be so increased in
the depth of cavity that the ax shall not be compressed or brought to its exact final
thickness, in order that it may he 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 what I 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 t will also be understood that by pro-
viding the cavities, c, for the excess of metal, and entirely surrounding the cavities of
all kinds by the body of the die-block, my dies are constituted closed dies in contra-
distinction to open dies, and consequently they may be brought together in such
manner as to produce in 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 ain 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.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declue that what I
claim 18-
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, C, C, substantially as and for the
purposes set forth
2 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 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, d, for the eye-pin, one part being also
formed with anvils, B, B₁, and the other part with corresponding cavities, C, C,
substantially as and for the purposes set forth
4 A two-part die for forming axes and the like, provided with a cavity corre-
sponding 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
