page_text: LETTERS PATENT to Edward Thomas Hughes, of the Firm of Hughes
and Son, Patent Agents, 123, Chancery Lane, London, for the
Invention of "IMPROVEMENTS IN HORSE-SHOE MACHINES."-A commu-
nication from abroad by Edwin Saxton Wheeler, of the City of
New Haven, in the County of New Haven, in the State of
Connecticut. United States of America.
PROVISIONAL SPECIFICATION left by the said Edward Thomas
Hughes at the Office of the Commissioners of Patents, with his
Petition, on the 29th December 1873.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes and Son,
Patent Agents, 123, Ohancery Lane, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN HORSE-SHOE MACHINES,"
a communication to me from abroad by Edwin Saxton Wheeler, of the
City of New Haven, in the County of New Haven, in the State of
Connecticut, United States of America, to be as follows:-
The nature of this Invention consists in a machine for cutting off,

page_text: forming up, and pressing horse-shoes from a continuous bar of metal or
from a bar of shoe blanks formed by rolls.
The Drawings represent a double machine capable of making two
shoes at the same time.
Figure 1 represents a front view; Figure 2, a side view; Figure 3, a 5
top view; and Figure 4, a squeezing pad as arranged to crease the
shoe.
In this machine the movements required required to complete the shoe
are derived from the reciprocating movement of the saddle A, A, moving
upon the upright guides R, R, and operated by the cranks b, b, and con- 1
necting rods B, B. I change and adjust the length of these rods by
means of the thimbles C, C, containing a right and left hand screw, so
that by turning in one direction the rod is lengthened, and by turning
in the other it is shortened.
The saddle bars A¹, A¹, are made adjustable by means of the 1
screws c, c, c, c, and washers a, a, a, a, in order to accomodate the
machine to shoes of different sizes or lengths.
D, D, are the rolls which operate the squeezing levers E, E. These
rolls are made adjustable by means of the connecting rods P, P, to be
lengthened or shortened by means of the adjusting thimbles ff, with 2
right and left screw.
G, G, G, G, are slotted formers, carrying the former rolls H, H, H, H.
These rolls are made to form the shoes around the discs I, I, or mandrils
placed upon opposite sides of the anvil F by means of the inclined cam
surfaces p, p, p, p, and adjustable rolls i, i, i, i.
The springs j, j, operate to hold the squeezing levers E, E, against
the rolls D, D, and the horn or forks h, k, to pull the shoe from the die
after it is finished.
M is the knife and guage holder, operated from the saddle bar A¹ by
means of the slotted connecting rod K.
L is the trimming guage and N the butting guage, either partaking of
the movement or acting in concert with the knife holder M.
S and T are adjustable knives for cutting the blanks to the proper
length. The knife T and butting guage N are brought back to a central
position by the springs t, t.

page_text: Upon the saddle bars A¹, A¹, are the spurs m, m, m, m; which operate
to squeeze the end of the blank before the shoe is turned.
The formers G, G, G, G, are connected to the shafts g, g, by means of
universal joints, allowing motion in any required direction.
O is a bar containing a number of rolled shoe blanks, having upon the
inner edge of the blank in a central position between the creases n, n, a
notch 0, for the purpose of determining the length of the shoe by means
of contact in any suitable manner with the cutting-off guage L. Tho
combination of these creases and intermediate notch in the centre of the
blank is included in this Invention.
In case the shoes are formed from a common bar of iron the squeezing
pad J, shown in Figure 4, may be used, having arranged to stamp tho
creases in the shoe as it is formed.
In practice I prefer to use two machines in combination with a pair
of rolls, one spare machine to be in readiness for use in case of accident
to the other. They may for this purpose be placed on wheels, and be
moved back and forth from the rolls upon a truck.
The iron is delivered from the rolls with any convenient number of
blanks upon each bar, having in the centre of each a guage mark by
which the blank is to be guaged, so as to be cut off from the bar, and
turned at an equal distance from the centre of the shoe, thus preventing
it from being formed unequally. This mark is a notch of any convenient
size rolled into the creased face of the blank, and on its inner edge,
bringing the mark directly over the concave of the shoc as produced in
the machine, by which means the mark is obliterated.
The iron is to be taken in a heated state immediately from the rolls to
the machine, the mark in the centre of the forward blank being moved
up
to the guage. The knife trims off the surplus end while the machine
is making the upward movement; but when the machine is making the
downward movement and the forming rolls have come to a rest the bar
is to be moved across the machine until it strikes the butting guage.
The knife now makes a counter movement, cutting the blank from the
bar. The blank is then squeezed upon the ends by the spurs upon the
saddle bars. Then begins the upward movement, relieving the knife
from its extreme throw and allowing it to assume a central position
through the action of the springs for that purpose. As the saddles

page_text: continue the upward movement the former rolls come in contact with
the blank, and by their action form it around the dies. Then the
squeezing rolls come in contact with the cam of the squeezing levers,
and by their action pressing the blank against the dies complete the
shoe. As the squeezing rolls pass the highest part of the cam on the
squeezing lever this lever is thrown from the dic by means of the spring
at its lower end, thus taking the finished shoc from the die by means of
the horns or forks for that purpose.
The shoe may be caused to drop upon an endless band, and by this
means be conveyed to any desired point.
I am aware that for the use of springs in this machine could be sub-
stituted cams driven from the main shaft, or lovers and weights might
be used, therefore I include all such devices as equivalent.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Thomas Hughes in the Great Seal Patent 1
Office on the 27th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents,
123, Chancery Lanc, London, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 2
Patent, bearing date the Twenty-ninth day of December, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Edward Thomas Hughes,
Her special licence that I, the said Edward Thomas Hughes, mys
exccutors, administrators, and assigns, or such others as I, the said
Edward Thomas Hughes, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN HORSE-SHOE MACHINES,"
a communication to me from abroad by Edwin Saxton Wheeler, of the
City of New Haven, in the County of New Haven, in the State of Con-

page_text: it from being formed unequally. This mark is a notch of any convenient
size rolled into the creased face of the blank, and on its inner edge,
bringing the mark directly over the concave of the shoe as produced in
the machine, by which means the mark is obliterated.
The iron is to be taken in a heated state immediately from the rolls to
the machine, the mark in the centre of the forward blank being moved
up to the gauge. The knife trims off the surplus end while the machine
is making the upward movement, but when the machine is making tho
downward movement and the forming rolls have come to a rest the bar
is to be moved across the machine until it strikes the butting gauge.
The knife now makes a counter movement, cutting the blank from the
bar. The blank is then squeezed upon the ends by the spurs upon the
saddle bars. Then begins the upward movement, relieving the knife
from its extreme throw and allowing it, to assume a central position
through the action of the springs for that purpose. As the saddles
continue the upward movement the former rolls come in contact with
the blank, and by their action form it around the dies. Then the
squeezing rolls come in contact with the cam of the squeezing levers,
and by their action pressing the blank against the dies complete the
shoe. As the squeezing rolls pass the highest part of the cam on the
squeezing lever this lever is thrown from the die by means of the spring
at its lower end, thus taking the finished shoe from the die by means of
the horns or forks for that purpose.
The shoe may be caused to drop upon an endless band, and by this
means be conveyed to any desired point.
I am aware that for the use of springs in this machine could be sub-
stituted cams, driven from the main shaft, or levers and weights might
be used, therefore I include all such devices as equivalents.
Having thus described the nature and particulars of the said Invention,
I claim,―
First. The arrangement and combination of the adjustable guage L,
knife holder M, adjustable knives T and S, adjustable butting guage N,
spring t, and slotted bar K, as herein set forth and for the purposes
described.
Second. The combination of the anvil F. mandrels I. I. pads J. J.

page_text: Third. The combination of the above devices with the cranks b, b,
adjustable shafts B, B, saddles A, A, saddle bars A¹, A², spurs m,m,m,m,
axle g, g, adjustable connecting rods P, P, rollers D, D, slotted cam
formers G, G, former rollers H, H, and adjustable rollers i, i, as herein
set forth, all arranged and combined so as to form a complete machine
for making horse-shoes as described.
In witness whereof, I, the said Edward Thomas Hughes, have here-
unto set my hand and seal, this Twenty-sixth day of June,
in the year of our Lord One thousand eight hundred and seventy-
four.
