I, MARK AMOS, of Westbury-on-Tyrm, in the County of Gloucester, Engineer,
do hereby declare the nature of this invention to be as follows :-
Under this invention the shoes are, by suitable machinery, bent in the cold state
to the proper shape, instead of, as hitherto, being heated and shaped by hand.
The iron, steel or other suitable metal of which the shoes are to be made is cut
into short bars of the requisite lengths and these are then laid in turn against the
upper ends of two adjustable grooved blocks secured on the face of an inclined
table and having a space, varying with the size of the shoe to be made, intervening
between them. The bar extends across this space and is adjusted by a gauge so
that its middle part is coincident with the middle of the said space. One end of
an arm having reciprocating motion over the face of the table, which motion is
imparted by a disc crank or other means, is made to bear against that part of the
bar which is opposite the space intervening as aforesaid between the adjustable.
grooved blocks between which the bar is now forced by the reciprocating arm.
The end of the arm is rounded and, consequently, the bar is bent at the middle in
conformity therewith, the sides being straight. The rounded part of the recipro-
cating arm may vary in size.
The bent bar is next placed over a block which corresponds in shape and
dimensions with the shoe being made. This block is secured either to the inclined
table above mentioned or to a similar table. The bar is held in place against the
block by a hand lever or other device.
Upon the table are pivotted two levers arranged in a form resembling a pair of
pincers. The lower extremities of the levers, i.e. those which are towards the
shaping block, are normally kept apart by means of springs secured at one end to
the table and bearing at the other on the backs of the levers.
Towards the other extremities the levers are normally kept in contact by the
said springs. To the outer end of the reciprocating arm aforesaid, or of a similar
arm, fs fitted a wedge-shaped head the point of which enters, in the down stroke
of the arm, between the upper ends of the levers and forces them apart at that
point. The lower ends consequently close and the free ends or heels of the shoe
are thereby bent to correspond with the curvature of the shaping block: When
the wedged-shaped head of the arm'is withdrawn the shoe is free to be removed
and it is then ready to have imparted to it such degree of concavity (if any) as
may be desired, and to be furnished with the usual groove,

page_text: For these operations it is made red-hot, and the operations may be performed by
placing the shoe under a press fitted with dies properly shaped therefor, which
dies are impressed upon the shoe. The operations may, however, be performed by
hand in the ordinary manner.
Iron or other suitable metal of the section known as "horse-shoe" section is
easily bent while cold, by the shaping machinery or apparatus aforesaid, into the
required shape, and the liability to injury attendant upon shaping with a hammer
is obviated.
Animals, and in Machinery or Apparatus therefor.
I, MARK AMOS, of Westbury-on-Trym in the county of Gloucester, Engineer,
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 improvements in the manufacture of shoes for horses, mules and other like
animals to which this invention relates, consists in bending by machinery, and in
the cold state, the bars from which the shoes are formed, instead of, as hitherto,
first heating them and subsequently shaping them by hand tools..
The iron or steel of which the shoes are made is cut into bars of the requisite
length and each bar is laid in turn against two grooved shaping blocks secured by
clamping screws on a table which is preferably inclined at a suitable angle. The
blocks, which are adjustable horizontally, are. clamped at a distance apart which
varies with the size of the shoe required; and across the space intervening between
them the bar extends. By means of a gauge the bar is adjusted so that its middle
is coincident with the middle of the space between the blocks.
Above the table and having reciprocating motion midway between the blocks is
a plunger, the outer end of which is furnished with a rounded and grooved head.
This head varies in size with the shoe and is attached to the plunger by a clamping
screw. In the forward or down stroke of the plunger the bar, placed as aforesaid
against the blocks, is forced between the blocks and bent in the middle in con-
formity with the rounded head of the plunger.
The bar thus partly shaped is next placed over a block or die of the requisite
shape and dimensions and secured either to the table above mentioned or to a
separate table.

page_text: Upon the table are two levers which lie thereon and are pivotted thereto. The
ends of the levers which are towards the shaping block or die last mentioned are
normally kept apart by means of springs secured at one end to the table and
bearing at the other against the outer sides of the hinged levers, which towards
their upper ends, are thereby normally maintained in contact.
Above the table and having reciprocating motion midway between the hinged
levers is a plunger, the outer end of which is fitted with a wedge-shaped head,
which enters, as the plunger is moved forwards, between the hinged levers and
forces them apart at the top. The lower or outer ends are consequently made to
approach one another, the heels or straight ends of the partly shaped shoe are
forced upwards against the block and are thus made to correspond with the curva-
ture thereof. During the squeezing process the shoe is acted upon at the front or
toe by a lever which maintains the shoe against the corresponding end of the
block.
The plunger having now been withdrawn, the shoe is removed and is ready to
have imparted to it such a degree of concavity as may be desired and to be furnished
with the usual groove.
Referring to the accompanying sheet of illustrative drawings, Fig. 1 thereon
represents a plan of the machinery whereby the shaping of shoes for horses, mules,
and other like animals is, according to this invention, effected. Fig. 2 is a horizontal
section on the line a a Fig. 1, and Fig. 3 is a similar section on the line bb, Fig. 1.
By means of the plunger or reciprocating bar A the shoe is first partly shaped.
By means of the plunger or reciprocating arm B the curvature of the shoe is
completed. The bar c which is to constitute the shoe is first laid against the upper
ends of the shaping blocks d grooved as indicated in dotted lines. It is kept at
the required level above the table by flanges formed on the blocks. The blocks d
are adjustable on the table D by means of the bolts e passed through slots cut in
the table. The blocks are reversible. The table D may be inclined downwards
towards the blocks. By the gauge f the bar c is adjusted so that. its middle is
coincident with the middle of the space intervening between the blocks d. On
the table and having reciprocating motion in a plane midway between the blocks d
is the plunger A, the outer or thrusting end of which is furnished with a rounded
and grooved head N secured on the bar by the clamping screw 2. Heads of
different size are employed according to the size of the shoe to be produced.
In the forward or down stroke of the plunger A the bar c is forced downwards
between the blocks and bent in conformity with the rounded part of the plunger
head and the inner sides of the blocks d. A representation of the partly shaped
shoe is shown in dotted lines. The bar c, thus partly shaped, is transferred, without
being heated, to the block or die d' secured to the table D upon which are pivotted
the levers / capable of turning on the pivot pins m. Bearing against the backs of
the levers h are springs n attached at one end to the studs n¹ secured to the table.
The normal tendency of the springs n is to keep the levers h in contact towards
their upper ends and, consequently, apart at the lower ends. On the table and
having reciprocating motion in a plane midway between the levers h is the
plunger B furnished at the lower or outer end with a wedge-shaped head G secured
upon the bar by the clamping screw g. As the plunger B is thrust forward in the
down stroke, the head G entering between the levers h forces them apart at
the upper ends, and, consequently, the lower ends close upon the heels or free ends
of the shoe c which are forced against the sides of the block or die d¹ which is
shaped to the final curvature required for the shoe and to which the shoe now
conforms.
By a lever o situated below the die d the shoe is, during the process of being
pinched, held against the die, the lever being brought to bear against the toe of the
shoe. Under the lever is a spring o' which normally tends to depress the inner end
of the lever o from contact with the shoe.
The requisite reciprocating motion may be conveniently imparted to the plungers
A and B by the crank shaft E and connecting rods F.

page_text: When the plunger is withdrawn the shoe is removed and subsequently finished
either by hand or in a press fitted with dies properly shaped therefor.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :
1st In the manufacture of shoes for borses, mules and such like animals, the
employment of a plunger such as A, with a head such as N, having reciprocating
motion between adjustable grooved blocks such as d whereby the bars for the shoes
are partially shaped in the cold state, substantially as herein before described and
shown in the accompanying sheet of illustrative drawings.
2nd In the manufacture of shoes for horses, mules and such like animals, the use
of a plunger such as B, with head such as G, having reciprocating motion between
hinged spring levers such as h arranged to force the heels or straight ends of the
shoe against a properly shaped die or block d¹ whereby the final curvature is
imparted to the shoe, substantially as herein before described and shown in the
accompanying sheet of illustrative drawings.
3rd In the manufacture of shoes for horses, mules, and other like animals, the
combination of a reciprocating plunger A and blocks d for partially shaping a shoe,
a reciprocating plunger B, levers h and block or died for completing the curvature
of the shoe, and means for operating the said plungers and levers, substantially as
herein before described and shown in the accompanying sheet of drawings.
Dated this 21st day of July 1886.
