Improvements in Machines for Bending Horse Shoe Blanks.
I, JOHN DOUGLAS BILLINGS of No. 216, W. 13th Street, City County and
State of New York United States of America Attorney-at-Law, 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 :-
My object and purpose in this invention is to produce a machine for bending or
forming horse and mule blank bars into the required shapes, and by its differently
constructed and improved mechanical parts, operate a bending punch and oscillating
cam jaws and bend the said blanks into shoe shapes, and release the said shoe from
the machine without the use of hand power and without the use of any of the
devices heretofore in use and with less complications and more cheaply, perfectly
and rapidly.
After the blank shoe bars are taken from machines for forming blank bars for
horse-shoes, and while hot, they are passed through the cutter attached to the
bending machine and which is operated in conjunction with the said bending
machine and cut in two at the proper place into the required lengths. These
separated shoe blanks pass immediately into the required position for bending. The
bending machine and cutter attached thereto lying in a horizontal position.
The shoe blanks lay or rest in two small rolls which supports the shoe blank at
each of its ends, before the operation of bending them commences.
The shoe blanks are held by adjustable gauges to prevent the bar from moving
either way and holds it firmly while the plunger or punch die passes the blank shoe
bar down into the oscillating jaws.
The adjustable spring placed at the extreme lower inside ends of the oscillating
jaws, controlling both of the said inside ends of the said jaws at one and the same
time, by allowing the said jaws to close up around the said blank shoe when it
encircles the said punch die and is being formed into shoe shape, and also presses
the jaws up and spreads them at the extreme upper ends, allowing the punch die to
return to its place, carrying the shoe with it and leaving the jaws open at the said
upper ends ready to receive another shoe blank.
The plunger or punch die then stops over the aperture or space left or måde in
the foundation or table plate of the proper size and on which are placed ways on
which the punch die moves backwards and forwards.
The bent shoe having reached this vacant space or aperture in the table plate,
there is nothing to support it or hinder it from falling and it falls to the ground
and is released from the bending machine by its own weight.
By these improvements the only hand power required is in taking the blank shoe
bar from the machine for forming blank shoe bars and passing it through the proper
place in the cutter and after being cut in two, adjusting the ends of the said blank
shoe bar in the said gauges.
The invention consists of an elevated table or bed plate laying in an horizontal
position and resting upon legs leaving an open space underneath the same and
provided at the proper place in the said table plate an open space or aperture for
the sole purpose of allowing horse and mule shoes after being bent from the blank
shoe bar into the said shoe shapes, to be released and freed from the bending
machine, and the mechanical parts of the same by its own weight, also an adjustable
spring for controlling the jaw dies while the blank shoe bar is being formed into a
shoe shape, also gauges to hold the ends of the blank shoe bar firmly while being
operated upon by the punch die, also a cutter for separating the blank shoe bars
and being made apart of the said bending machine and working in conjunction
thereto and serving as a feeder to the same, and the combined mechanism for

page_text: operating the said machinery, also the punch die running upon ways and operated
by the rod or sweep moving through the pitman.
In the accompanying drawing,
Figure 1 represents the bending or forming machine resting upon legs, a top or
upper side view looking down upon the machine, laying or resting as it works in an
horizontal position.
Figure 2 represents the cutting and feed device which is attached to and made a
part of the bending machine, a side view of the same the legs of the table at the
ends of the side of the bending machine to which the cutter is attached, also
the clutch and bar, and the cam that operates the cutter.
Figure 3 shows the oscillating jaw dies, the rolls upon which rests the blank
horse shoe bar before bending, the said jaw dies being covered with a cap, also the
adjustable spring which holds and controls the said jaw dies, moving to and fro
upon their pins or pivots, and showing the forming part of the punch die inclosed
in the jaw dies.
Figure 4 represents the plunger or punch die P, showing where the rod or sweep
is attached to it, and which works in the pitman of the bed or table and in ways.
Figure 5 represents the punch die or plunger raised on and laying on its edge
showing its side shape.
Figure 6 represents a view or showing of jaw dies made or formed out of their
inside edges in the form of the letter O, or as near round as possible, with the
punch die inclosed at its forming end.
This drawing is to show that rings of any desired circumference can be formed
or made by these jaw dies, operated by the other mechanical devices of the bending
machine, and also bar shocs, which are made to encircle the foot of the horse, and
worn upon thousands of horses feet that have drop soles, and to cure tender and
sore feet.
A A represents a bed plate or table-which is formed of cast iron or other suitable
material, and rests upon legs. B and S represent the pulleys run by means of a
belt R, and which are run by shaft D, and which moves the shafting and cam T
and operates the cutter shown in Figure 2.
00 represent the ways in which is placed the plunger or punch die, which slides
forwards and backwards in them. P. represents the plunger or punch die, and
carries and bends down the blank shoc bar into the oscillating jaw dies C, C.
N represents the sweep or rod beam in the pitman attached to the punch die P',
by a slot and pin bolt, the lower end of the rod beam, moves loosely on the pin
bolt. The other end of the sweep or rod beam is attached to the cam G.
Revolving around the cam pin E, E, are the boxes in which the shafting D
revolves.
U represents the aperture or space made in the bed plate or table A. A through
which the shoe falls, and is released from the plunger or punch die, after being
formed into a shoe shape by the punch die and oscillating jaw dies C. C.
C, C, represent the jaw dies which receive the shoe while bent around the
plunger, and in combination with the punch die form and give particular shape and
contour to the shoe. A cap or plate covers these jaw dies.
c and c represents the adjustable spring at the middle lower ends of the jaw
dies C, C, and hold and control the movements of the said jaw dies at the ends
which receive the punch die with the shoe bar, opening to receive the said shoe bar,
closing when the shoe is being shaped, and opening again to discharge the said
punch die and shoe, and kept open to receive another bar. W represents the space
between the jaw dies C, C, on the bed plate or table A, A, and under the cap that
covers the jaw dies. w, w¹, represent the turning rolls upon which rests the blank
shoe bar ready to be bent, and assists the punch die P in bending the bar down-
wards into the jaw dies C, C.
V, V, represent adjustable gauges secured to the table A, A, by a slot and
screw, holding firmly the shoe bar in the proper required position to be bent by the
punch die P.

page_text: H represents the pulley, which when belted and given power, turns the shaft D,
and the pulleys B and S and cam T, and which operates the cutter X in Figure 2.
M and I, represent the clutch used to move on or off the power that runs the
combined machines. J represents the clutch pin that holds the clutch bar to the
clutch, and R is the clutch bar.
L represents the arm or brace that supports the outer end of the clutch, and
X shows the cutter, Figure 2, which is operated by the cam T.
The operation of the machine is as follows:-
The blank shoe bars, when hot, are taken and the end thrust into the rolls w, w,
and through the cutter at X and the clutch M, I, K, thrown on, and the cutter
moves first and separates the blank shoe bar as it lays firmly between the
gauges V, V. The punch die P instantly follows and bends the blank shoe bar
down into the forming jaw dies C C.
The punch die returns with the bent shoe and passing it exactly over the space U
in the table bed A, A, it stops, and the shoe drops through and out. The next
blank shoe bar is cut, leaving two blank shoe bars to be treated in like mauner as
the first, taking about four or five seconds to cut and bend three blank shoc bars
into shoe shape.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is:
