Improvements in Machines for use in the Manufacture of
Horse Shoes.
I, JOHN. DOUGLAS BILLINGS, of 216 West 13th Street, New York, United States of
America, Attorney, 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 :-
The object of this invention is the construction of a machine for the manufacture
of horse and mule shoe blanks from iron and steel bars of the required size, with
calks in their proper places or with continuous calks or made plain with proper
bends and indentations or holes for nails, the said blanks being afterwards bent into
the desired shape or contour.
The utility, novelty and advantage of this invention for forming iron and steel
bars, of a required size into certain special shapes, over the old and present devices
by two or more rolls and by a pass, or quick roll movement, is as follows; Instead of
rolling the bars by a rapid pass movement between the rolls, and making the
depressions or spaces between the calks, and leaving the projections in the bar at
the necessary places to be used as calks, and at the same time, making the blank
shoe-bar, thus rolled, of uniform lengths, and the said spaces and calks of uniform
lengths and sizes, and also to prevent a waste of metal and further to prevent the bar
when passing through and leaving the rolls, from twisting and clinging to the groove,
in and bending around the roller, and which has heretofore never been successfully
accomplished, the bars when heated are placed on the projections or raised die-slots
on the die-plate and they remain in a straight, level firm position during the passing
of the die-plate under the top die-grooved roller, which latter acts as the female die,
and the die-plate with the raised projections acting as the male die, the said die-plate
and the said top die grooved roller moving in the same directions, the top die-grooved
roller making its revolution, being placed or resting at each end upon housings and
held firmly in them, the die-plate passing under the said top roll, and carrying the
bars the whole length, the top die-grooved roll making, at the same time, one
complete revolution and forming and shaping one complete shoe bar, or blank, thus
effecting the bars by making the depressions, or spaces, and leaving the projections in
them for the calks, also at the same time, making the small depressions for the nail
holes, and all this by a roll forged-die movement combined.
The result of this manner of forming the bars or blanks is that the calks and spaces,
and indentations are of uniform size, shapes and lengths, and the said bars do not
twist, nor bend, nor cling to the upper roll, and it also prevents a waste of the bar,
as all the bars before being heated and placed on the die-plate, are cut off the
required length. This novel mechanism does away entirely with the under roll, or
in other words, the blank shoe-bar is formed into the detailed shapes required for a
horse and mule shoe, by using one roll and with the assistance of the said die-plate,
which takes the place of the bottom roll.
By the use of this invention, horse and mule shoes can be made much faster and
cheaper and more perfect than heretofore. From one to six shoe-bars of different
kinds to wit; a 3 calked; a 4 calked; a plain; a flat; or a continuous calked shoe
blank, or a shoe blank with serials of calks, can be made at one and the same time, by
one revolution of the top roll and one passing of the die-plate, as all these several
shaped die-grooves can be made in the top roller, which will form these different
shapes of shoe blanks.
.
The invention consists of a movable die-plate, with a die-grooved or forming roller;
between which iron or steel bars are carried and formed into shapes ready for bending
nto horse and mule shoes and the mechanism for operating the same,

A, represents the bed, B the housings in which turn the forming roller C, running
in conjunction with the die-plate D, which is carried by means of rack E, and
pinion F. The die-plate D, moves with the roller C, by means of their connection
through the rack E, pinion F, shaft G, and pinions H, and I. J represents the
frames supporting the guide plates j, against which the webs, k k work for the purpose
of guiding the die-plate, K the roller upon which the die-plate D moves, L the driving
pulley which has constant motion.
Figures 4, 5, 6 and 7 show different views of the internal and external parts of the
mechanism for moving the die-plate backwards and forwards. Figure 1 clearly shows
that the dye plate is moved by the turning of the top or grooved roll and by the gear
attached to the top roll and this gear falls into the companion gear attached to the
bottom or main roll which carries the die plate Figures 4, 5, 6 and 7 when taken in
connection with Figures 1, 2, 8, 9 and 10 will show the changes or different views of
the mechanicism for carrying the die plate forwards when loaded with bars of iron to
be rolled or formed into shoe-blanks and the reverse movement for taking back the
die plate to its place from whence it started to be again loaded up.
The operation is as follows:-
The iron or steel bars to be used having been rolled or formed into an approxi-
mately correct shape, including the formation of the tread, or creasing for the nail
holes, by the usual methods, are cut into the proper lengths, then heated and
placed upon the raised part a, of the die-plate D, while the latter is in its first
position, the clutch M is then thrown into engagement with gear N which transmits
motion through gear O, roller C, pinions I, and H, shaft G, pinion F, and rack E, to
the die plate D, carrying it forward with speed corresponding to that of roller C
and guiding the iron into the annular grooves c which contain the depressions c¹ and
projections and c³, which form the calks d, and depressions d', and also depressions d
for nail heads. The depressions and projections in the annular grooves may be made
of any form or shape to produce a blank bar, with or without calks, or a continuous
calk, or plain or flat and bevelled shape.
The bar having been carried through the former by means of gears O, and N, the
machine is stopped in position as shown in Figure 1 by disengaging the clutch M, and
engaging it with the gear S, which transmits a quick reverse motion to the gear T,
through the intermediate gear U. The bars are then in condition shown in Figures 13

page_text: and 14, having the flat face as in Figure 12, for hind shoes or with bevel d³ Figure 17
for front shoes. The nail openings are punched through d², and bar bent to perfect
shape.
