I, FREDERICK A. ROE, of the City and State of New York, United States of
America at present residing at 42 Fairholme Road, West Kensington, in the County
of Middlesex Gentleman, do hereby declare the nature of my invention for
IMPROVEMENTS IN THE MANUFACTURE OF HORSE-SHOES AND IN MACHINERY OR
APPARATUS THEREFOR" to be as follows:-
"
My invention relates to the manufacture of spring and other horse-shoes and to
machinery or apparatus therefor, and comprises various improvements hereinafter
described.
In the Specification of former Letters Patent dated 5th July 1882 N° 3177, the
manufacture of spring horse-shoes by means of specially designed machinery or
apparatus is described. This apparatus comprises a pair of dies for drawing the
bianks and forming the heels or calks, and another pair of dies for finishing the
blanks; but by these dies only one half of the blank can be pressed into shape at
a time, and, after one half of the blank is formed, the said blank must be turned
around and the other half thereof inserted between the dies, so that the two ends
of the blank will be formed to suit the right and left hand sides of the shoe.
One object of my present invention is to enable a billet or bar of inetal of
sufficient length to form one or more blanks, to be thus shaped by being only once
subjected to the action of each pair of dies. For this purpose I employ roller dies
provided with the requisite grooves and recesses for forming the blanks, and
finishing dies to be operated by a drop hammer, or in place of these fiuishing dies,
I use additional roller dies, all as hereinafter set forth.
My said invention, moreover, comprises an improved method which consists in
rolling a billet or bar of sufficient length to form a series of blanks (four for
example) and subjecting the said blanks to the action of dies operated by a drop
hammer as hereinafter described, or to the action of roller dies, before cutting or
severing them from the billet or bar. I thus obviate the necessity for using tongs
to lift the blanks out of the fire, when heated. The last two blanks are both
subjected to the action of the said dies before they are severed or separated.
My said invention is conveniently and advantageously carried into practice as
follows, viz:-I take a billet or bar of metal of sufficient length to form one or
more shoes. This billet or bar, after being properly heated, is subjected to the
action of roller dies, which are grooved so that they will impart the desired shape
to the blanks. One of the said roller dies, preferably the upper one, is provided
with recesses for forming the calks on the heels and toes of the blanks, when the

page_text: shoes are to be made with calks: It has also ribs which are forced into the metal to
form the creases in the blanks. The other roller die has protuberances which force
the metal out and thus reduce the thickness of the inner side of the blank and
make it concave for the springs of the shoe. After the bar is thus rolled to form
the calks, creases, and concaves, it is properly heated, and each blank is subjected
to the action of other dies for finishing it (including the calks creases and concaves)
and reducing it to the exact form.
These finishing dies are operated by a drop hammer. One of these dies,
preferably the upper one, is made with ribs and recesses to complete the calks and
creases in the blank. The said dies, moreover, finish the whole of the blank at one
operation. I prefer to make the ribs for forming the creases on the upper die, in
order that they may be exposed as little as possible to the heat, which would tend
to burn and soon destroy them. As the hammer strikes and rises quickly from
the heated metal very little injury can result from the contact of the said ribs with
the hot metal. The lower finishing die is made with protuberances to finish the
concaves and portion next to the horses' hoof for the springs of the shoe.
I sometimes use, in place of these finishing dies, a pair of roller dies formed with
the necessary grooves and ribs or projections.
The blank being forced in between the said finishing dies by the drop hammer,
any surplus metal is necessarily crushed out in the form of a "fin" or rough edge.
To remove this "fin" the blank is subjected to trimming dies of the same shape
as the blank, which dies remove the fin from the said blank. After the blank has
been calked, creased and concaved, and reduced to the desired shape, it is subjected
to the action of a bending machine.
.This machine is made with a table or support for the blank and for the formers
and forming dies and other parts, and at the centre of the said table or support is
an arm or ram which is attached at one end to a block sliding in a groove parallel
with the table. On the other end of the said ram is pivotted or screwed a forming
die of the shape which it is desired to give to the inner edge of the shoe. This
die can be removed and replaced by a larger or smaller die for different sizes of
shoes. This forming die is made with a shoulder or projection around it, which
bears upon the blank, thus holding it in place and preventing it from twisting
while it is being bent to form a shoe. The said forming die has also a short sharp
pin or point in the centre of its front portion to pierce the billet in the centre and
prevent it from slipping while being bent.
On each side of the forming die are secured adjustable guides provided with
anti-friction rollers, between which moves the forming die. The said rollers press
against the shoe blank while the ram is moving forward and thus bend the said
blank. The ram pushes the forming die with the shoe upon it, into a hinged
former with removable dies attached to the bottom thereof. These dies can, if
desired, be removed and replaced by other dies according to the size of the shoe to
be made. The former is connected with the adjustable guides by blocks which
are hinged to the said guides and to the former, so that when the forming die is
pushed forward, the former will close around the same and press the shoe forcibly
against it; the inside edges of the shoe will therefore assume the shape of the
forming die, while the outside edges of the shoe will be pressed into the shape of
the inside of the dies attached to the former. When the ram returns it opens the
former and carries the shoe back with it and allows the said shoe to fall on the
floor or into a receptacle through a hole made in the table of the machine for
the purpose.
The blank is introduced into the machine as follows, viz:-when the said blank
has been properly heated, it is pressed transversely between two adjustable springs
attached to the table of the machine, and in front of, and against the said forming
die; these springs bear against the ends of the blank and act as gauges, as they
will not receive the blank unless it is of the. proper length. This machine with the
said rain and former can be operated by any of the well known cam devices, so as
to cause the said ram to move backward and forward on the table.

page_text: After the shoe has been formed, it is subjected to the action of other dies for
cutting the ends of the shoe to form the rear of the springs.
In order to make the rear ends of the springs inclined or bevelled so that they
will bear against the heels of the shoe proper (when the said shoe is forced down
upon the springs by the horses weight) it is necessary to first make downward cuts
in the shoe at the heels, on the proper incline and also side cuts to meet the said
downward cuts to prevent the metal from tearing or breaking when the shoe is
being cut or sheared as hereinafter described to form the springs. This I accomplish
by means of a machine which makes four cuts simultaneously, or approximately so.
This machine has an adjustable die for holding the shoe in place while the ends of
the springs are being cut. The ends of the springs are cut by means of dies or
plungers holding peculiarly shaped blades formed somewhat like the coulter of a
plough, and straight edged blades.
The two upper dies with the peculiarly shaped blades fastened in them are
attached to two rams or plungers working vertically. The two side dies with the
straight edged blades fastened in them are attached to two rams or plungers
working horizontally.
The shoe is laid flat on the adjustable die which holds it securely, and the heels
are then cut. The peculiarly shaped blades penetrate the heels perpendicularly on
the inside (that is to say, the part which is to be next to the horse's hoof) from the
ends of the heels forward. The straight edge blades penetrate the shoe at right
angles to the other blades on the outside edges of the shoe from the ends of the
heels forward and sloping downward. These two cuts in each heel meet so as to
separate the heels of the springs from the shoe proper and make them with the
desired lap, by one operation of the machine.
In some cases, after the billet or bar has been subjected to the action of the roller
dies, each blank is bent into the form of a shoe and is subsequently subjected to
the action of a pair of dies operated by a drop hammer for completing or finishing
it. In this case the drop dies are made the shape of the shoe, to receive the shoe
exactly as it comes from the bender. The recesses and ribs for the calks and
creases of the shoe may be either in the top or bottom die, and the protuberances
for forming the concaves and parts for the springs of the shoe in the opposite die
or the dies may be formed to make shoes without calks.
After the shoe has been formed and partially cut to form the springs as above
described the said shoe is subjected as described in the said former specification to
dies for cutting or shearing the same to complete the springs. The lower of these
dies has an opening or recess just large enough to receive the spring portion of the
shoe, including the calk, while the upper die is made to fit this recess.
The face of
the lower die is so bevelled that it first strikes on the heel of the shoe and then
cuts forward with a shearing cut, as far as desired to sever the spring from the side
of the shoe proper, The nail holes are then punched.
I sometimes so construct and arrange the roller and drop dies as to leave a small
quantity of surplus metal at the toe of the shoe in the shape of a small "cube,"
which will be pushed into place to form the toe-clip by the spring-setting or
finishing dies. And I form a concavity and protuberance in the toe of the spring-
setting dies to form and receive the toe-clip without disfiguring the toe of the shoe
by taking metal therefrom as described in the said former specification.
The above described spring setting or finishing dies are subjected to the operation
of either a drop hammer or a power press.
If it is desired to make horse-shoes without springs the operation of cutting the
shoe to form the springs is dispensed with.

page_text: Machinery or Apparatus therefor.
I FREDERICK AUGUSTUS ROE, of the City and State of New York, United
States of America, at present residing at 42 Fairholme Road, West Kensington, in
the County of Middlesex, Gentleman, do hereby declare the nature of my invention
for "IMPROVEMENTS IN THE MANUFACTURE OF HORSE-SHOES AND IN MACHINERY
OR APPARATUS THEREFOR" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to the manufacture of spring and other horse-shoes, and to
machinery or apparatus therefor, and comprises various improvements hereinafter
described.
In the specification of former Letters Patent dated 5th July 1882 N° 3,177 the
manufacture of spring horse shoes by means of specially designed machinery or
apparatus is described. This apparatus comprises a pair of curved dies for drawing
the blanks and forming the calks thereon and another pair of dies for finishing the
blanks, but, by these dies, only one half of the blank is operated upon at a time,
that is to say, after one half of the blank has been shaped or finished by either pair
of the said dies, the blank must be reheated and the other half thereof inserted
between the dies, in order that the two halves of the blank shall be shaped as
required for the two sides of the shoe.
One object of my present invention is to provide for the manufacture of horse-
shoes by one operation of each pair of dies employed.
An important feature of my said invention is the employment of rolls or roller-
dies, between which a bar or billet can be passed to form one or more blanks, and
which are made with ribs or projections to form the creases in the blanks, and, if
necessary, with recesses or cavities to form the calks thereon either at the heels, or
at the toe, or at any other part of the shoe.
In making horse-shoes according to any said invention, I prefer to proceed as
follows, viz I take a billet or bar of metal of sufficient length to form say four
shoes. This billet or bar is first properly heated, and is then subjected to the action
of the rolls or roller-dies to form the blanks. The blanks are then separated from
each other and heated, and are then bent by means of a suitable bending machine to
form shoes. They are then again heated and subjected to the action of drop-dies
(that is to say, dies operated by a drop-hammer) to finish the shaping of the shoes;
one of these dies, preferably the upper one, is made with ribs and recesses to
complete the creases and calks. The fin left by the said drop-dies is then trimmed
or cut off by any suitable means. An ordinary shoe, that is to say, a shoe without
springs, is thus formed.
If it is desired to make a spring horse-shoe, the shoe is placed in a machine
similar to that hereinafter described for cutting it to form the ends of the springs.
It is then placed in dies, substantially similar to those described in the said former

page_text: specification, to cut or shear the shoe to form the springs. The nail-holes are then
punched, and the springs are set and the shoe finished by means of suitable dies
operated by a drop-hammer or a power press.
The shoe is then tempered in any
convenient manner.
In some cases,
I roll a bar or billet as above described and then separate the
blanks and subject the same to the action of drop-dies and trim or cut off the pin
left by the said dies, before bending the blanks to form shoes.
I sometimes construct the drop-dies (whether used before or after the bending of
the blank) in such a manner that they will form the toe-clip on the shoe, and
I leave sufficient metal at the toe-part of the blank to form the said clip. In some
cases clips are formed at the sides of the shoe in a similar manner.
In the accompanying drawings,
Figure 1 is a front elevation, and
Figure 2 an end elevation shewing a pair of rolls or roller-dies made in accordance
with my said invention.
Figures 2 and 2b show blanks formed by means of the said rolls or roller-
dies.

the parts in the positions which they occupy when the machine is ready for
starting.
Figure 4 is a plan, and

the parts in the positions which they occupy when the operation of bending a
blank is completed.
Figure 6 is a transverse section on the line x, x, Figure 4.
Figure 7 is a sectional elevation of a die and die-holder hereinafter described.
Figure 8 is a plan, partly in horizontal section,

Figure 11 an end elevation of a machine for cutting the shoes to form the ends of
the springs.
Figures 12 to 20 show various details of construction hereinafter described.
Like letters indicate corresponding parts throughout the drawings.
In Figures 1 and 2, a, a are two frames or standards which are to be firmly
secured by bolts or otherwise to a suitable base-plate or foundation. b, b¹ are two
rolls or roller-dies, which are fitted to rotate in bearings a¹, a² in the said standards.
c, c are pinions keyed upon the axles of the said rolls and geared with each other,
so that, when motion is imparted to one of the said pinions from any suitable
motor, the said rolls will be rotated in opposite directions. The roll b is formed
with rings or annular projections 62 which fit into corresponding grooves or
recesses b³ formed in the roll b¹. These rings and grooves are of the same width
as the bar or billet from which the blanks are to be made. Each of the rings b² is
provided with ribs or protuberances b, which, when a bar is passed between the
said rolls, are forced into the said bar to form the creases; each ring 62 is, moreover,
provided with recesses or cavities 65 to form the calks. The rolls shewn are designed
for use in the manufacture of shoes having a toe-calk as well as heel-calks, but it
is obvious that my roller-dies may be adapted for making shoes without calks, or
with any other desired number of calks. The said rolls or roller-dies are constructed
so that they will impart to the bar or billet either the shape shewn in Figure 2º or
that shewn in Figure 2b. The blanks are to be severed froin each other at the
dotted lines in these Figures.
In Figures 3 to 7, d is the base-plate of the machine, e is a former, which is
designed to operate in combination with dies hereinafter described to bend the
blanks to the desired shape, and which is firmly attached by bolts el or otherwise
to the flattened end of a bar or rod e². This bar is secured by bolts or otherwise to
a block e fitted to slide to and fro between guides d', d² fixed or formed on the

page_text: base-plate d. The said block is coupled, by means of a connecting rod f, to the
pin g of a disc crank g, which is fixed upon a shaft h carried in bearings hl, and
which acts as a fly-wheel. A toothed wheel 2 is mounted loosely upon the shaft h
and is adapted to be connected therewith, or disconnected therefrom, by means of a
clutch ³, operated by a foot-lever or treadle i through the medium of the levers i¹, i².
jis a pinion which is fixed on a shaft j¹ carried in bearings * and which is geared
with the wheel h³. is a driving pulley fixed on the shaft j¹, which pulley is to be
connected by a belt with any suitable motor. By these means reciprocating motion
is imparted to the former e, for the purpose hereinafter specified.
k, kare dies whose inner edges have the shape or configuration which it is
desired to give to the shoe. These dies are firmly secured, by bolts or otherwise, to
blocks or holders k pivotted at ³ to a plate l resting upon the base-plated so that
it is free to slide thereon. is a tie-bar connecting the pivots of the holders k².
m, m¹ are two links, which fit into vertical grooves or recesses in the holders k² and
in blocks n, so that they will act like a toggle-joint. The blocks n have screw-
threaded extensions n', which are passed through lugs or brackets d³ formed on, or
secured to, the base-plate d, and are provided with nuts n². Washers or distance-
pieces n³ are placed upon the extensions n¹ between the blocks n and the lugs ɖ³ ;
by slackening the nuts n², removing the washers n³, and inserting washers of
greater or less thickness in place thereof, the dies k, k¹ and holders can be
adjusted to suit different sizes of shoes. The links m, m¹ are coupled to the
holders and blocks n by bars or links m³.
o, o are adjustable blocks provided with antifriction rollers o' and so arranged
that the former e, in its to-and-fro movement, will pass between them. These blocks
have screw-threaded extensions of, which are passed through lugs or brackets d'
formed on, or secured to, the base-plate d, and are provided with nuts o³. Washers
or distance-pieces o* are placed upon the extensions o², which washers can be
replaced by thinner or thicker washers as above described with reference to the
blocks n.
The said blocks o are formed with slots 0 and are secured to the base-
plate d by bolts of passing through the said slots.
P, p are springs attached to the blocks o for the purposes hereinafter specified.
is a weight attached to one end of a rope or chain which passes around a
pulley carried by a bracket d³ formed on the base-plate d. The other end of the
said rope or chain is attached to a rod passing through a guide-block" secured
to the said base-plate. This rod is attached by a bolt 3, or otherwise, to the
plate l.
The operation of the machine is as follows, that is to say -In Figure 3, the parts
are, as above stated, shewn in the positions which they occupy when the machine
is ready for starting. The blank B is placed endwise between the springs p, as
shewn, which springs hold the said blank until the former e acts thereon as herein-
after described. The said springs permit of readily ascertaining whether the blanks
are of the proper length to form a shoe of the desired size, because, if a blank is too
long, it cannot be inserted between the said springs, whilst, if a blank is too short,
it will not touch the two springs. After a blank of the proper length has been
heated and inserted between the said springs, as shewn, the treadle is depressed
to start the machine. The rotation of the disc-crank g first causes the former e to
move forward or towards the dies k, k¹. In this forward movement, a pointed
stud or projection et on the former e first enters the blank at the centre thereof,
and thus prevents its displacement while being bent; the said former then forces
the blank between the rollers o¹ and thereby bends the said blank; it then thrusts
the said blank between the dies k, k thereby moving the said dies and the plate
forward, this movement being assisted by the weight . The dies k, k', in their
forward movement, are turned around or about their pivots by the links m, m¹,
and the blank is thus forcibly pressed between the dies k, and the former e to
impart to it the required shape. The parts then occupy the positions indicated in
Figure 4, in which S indicates the shoe. While the blank is being bent, the

page_text: flattened head of the bar e' holds down the shoe and prevents the twisting or distor-
tion thereof. The continued rotation of the wheel g causes the backward or return
movement of the former 6. In the first part of this backward movement, the
plate and dies k, k move back with the former e so that the said dies are opened
by the links m, m¹; in the continued backward movement of the former e, the shoe
is withdrawn thereby from the dies k, and moved back with the said former
until it arrives over the aperture d in the base-plate d, through which aperture it
will fall upon the ground or into a suitable receptacle.
The former e and forming dies k, le are removable from the rod e² and the
holders k³, and can be replaced by other formers and dies; therefore the machine
can be adapted for manufacturing horse-shoes differing in size, or in shape, or in
both size and shape. The manner in which the dies k, klare secured to their
holders is more clearly shewn in Figure 7.
In the manufacture of spring horse-shoes, the rear ends of the springs should be
inclined or bevelled so that they will bear against, and support, the heels of the
shoe proper, when the latter is forced down and the springs are compressed by the
horse's weight. It is, therefore, necessary to first make downward or vertical cuts
in the shoe at the heels, and then inclined lateral or side cuts to meet the said
downward cuts, in order to prevent the fracture of the metal at these parts when
the shoe is being cut or sheared to form the springs. The machine shewn in
Figures 8 to 11 is designed for cutting the shoes in the manner above described to
form the rear ends of the springs. In these figures, q is the base-plate of the
machine, which is supported upon standards q¹. r is a holder firmly attached to
the said base-plate for holding the shoe to be cut. This holder is made in two
parts, formed with slots through which are passed the bolts for securing the
said holder to the base-plate q; the said pieces 1, 2 can, therefore, be adjusted
laterally towards, or away from, each other to suit different sizes of shoes.
said holder is formed with recesses or cavities to receive the heels of a shoe, and
thus ensure the holding of the shoe in the proper position to be cut, and with
grooves or notches for the purpose hereinafter specified.
The
8, & are the knives or cutters for making the downward or vertical cuts; these
knives are fitted in holders 81 and are held therein by means of set screws or
otherwise. The said bolders have screw-threaded extensions 83, whereby they are
secured, by means of nuts s³, in a lug t¹ formed on, or attached to, a bar t. This
bar is fitted to slide up and down between guides t² formed on, or secured to, the
bracket which is fixed or formed on the base-plate q. The said bar is coupled,
by means of a link t³, to one arm of a lever u pivotted at ¹ to the bracket q².
The other arm of the lever u is coupled, by a connecting rod u³, to the crank v₁ of
the crank shaft v, which shaft has three cranks v¹, ², . The connecting rod u is
provided with a screw u³ having right and left hand threads and with lock-nuts u*,
whereby the said rod can be lengthened or shortened as desired. The crank shaft v
is carried in bearings attached to the base-plate q; and is provided with a fly
wheel v³.
w, w are the knives or cutters for making the lateral cuts; these knives are fitted
in holders w¹ and are held therein by means of set-screws or otherwise. The said
holders have screw-threaded extensions w³, whereby they are secured in the
bars w³, and which are provided with lock-nuts w. These bars are fitted to slide
horizontally to and fro between guides q³ attached to the base plate q. The said
bars are coupled, by means of the links w³, to bars we fitted to slide horizontally to
and fro between guides q' also attached to the base plate q; they are also coupled,
by means of the connecting rods w³, to the cranks v², v³.
The cranks 1, 2, are all on the same centre, but, by reason of the fact that
the bars w³, we move in a horizontal plane, whilst the bar t moves in a vertical
plane, the knives or cutters 8 will operate a short time either before or after the
kuives or cutters w, according to the direction of rotation of the crank-shaft v;
but the said knives cannot operate simultaneously, and, therefore, cannot come in

page_text: contact with each other. The knives w, in effecting the lateral cuts, enter the
grooves or notches in the holder r, which permit the projection of the said
knives below as well as above the shoe.
In Figures 17 to 19, I have shewn a pair of drop-dies A, A¹, the lower one A of
which is made with a groove or channel A' and the upper one A¹ of which is made
with a projection A3, which will fit into the groove or channel A. The said
projection, however, leaves a space at the inner end of the groove or channel A², 60
that, when a shoe is compressed between the said dies, the metal will be forced
into the said space and a toe-clip will thus be formed on the shoe, as shown, for
example, at y in Figure 20, which is a perspective view of a shoe manufactured by
the means above described. In some cases, I make the spring-setting dies in a
similar manner for the purpose specified.
I provide the means bereinafter described whereby the shoe can be readily
removed from the lower die, after it has been operated upon therein, that is to say,
a forked lever C is pivotted at C¹ to the lower die A, and is coupled to two rods D,
which extend through holes in the said die so that they will bear against the
under-side of a shoe therein. This lever is arranged to be operated either by hand
or by the foot, or automatically by the same means whereby the upper die is raised,
or by any other suitable means.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is
