Improvements in Wire Drawing Machines.
We, CHARLES HENRY HAAG of 8 Hecker Street, Cleveland, County of
Cuyahoga, State of Ohio, United States of America, Mechanic, FRANK JONAS
STAFFORD of 836 Oakdale Street Cleveland aforesaid, Superintendent, and
FREDERICK LEWIS, of 55 Eagle Street Cleveland aforesaid, Electrician, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
This invention relates to wire drawing and has for its object to greatly facilitate,
expedite and reduce the cost of drawing wire, and the invention consists in the
combination with the wire-drawing machine of a rotary die substantially as herein-
after described.
In the accompanying drawing:-
-
Figure 1 is a front elevation of our new rotary die.
Figure 2 is a side elevation of the same.
Figure 3 is a sectional view of the rotary die as seen attached to the machine.
Heretofore wire drawing machines have been provided with rigidly fixed dies and
the wire drawn directly through them, and solutions of various kinds employed for
passing the wire through in advance of the dies. With permanent dies, too, a
considerable power is necessary to draw the wire through them for reducing it. In
the use of our rotary dies, the use of solutions and all similar adjuncts are entirely
dispensed with, and the power required to draw the wire through the die greatly
reduced, as the rotary movements of the die aid the passing of the wire, and also
serve to polish the wire and give it that fine, smooth surface so desirable, and which
the solutions are now used for.
In carrying out these results we construct the die as follows :—
A represents a block mounted on a bench of the usual kind used in drawing wire.
B is a bearing mounted on the edge of the bench consisting of a block having a
cap held by screws. Cis a disc having a large neck fitted to rotate in the said
bearing, having on the front a disc or wheel D securely attached, which may be
used as a pulley, a belt being applied and connected with suitable means for
applying power for giving rotary motion to said wheel and disc.
Through the centre of said wheel and neck is made an aperture for the passage of
the wire, and in the back face of the disc is made a cross slot for holding a die
plate E in which may be several different sized holes through which the wire is to
be drawn, the holes in said die plate being adjustable in line with the aperture in
the disc. F is a set screw for fastening the die plate in place.
The working of this die is obviously as follows:-
The die is made to revolve as the other parts of the machine are working, and as
the wire is drawn through, the revolutions of the die greatly assist in the reducing
of the wire and thereby lessening the resistance in drawing, as well as giving a
smooth and glossy surface to the wire.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A rotary wire drawing die constructed substantially as described in combination
with a wire-drawing machine as and for the purpose set forth.
