We, JOSEPH STUART ROMANES, 101, Danville Street, City of Sheffield, Farrier,
and ALLEN BELL, of 242, Brook Hill, Sheffield aforesaid, Manager, do hereby
declare the nature of our invention to be as follows:-
:-
Our invention relates to the manufacture of horse shoes, and more particularly
to the machinery by which such manufacture is carried out.
The object is the more rapid and effective manufacture, two shoes being bent,
shaped, heeled, dished and the nail holes punched at one operation or complete
action of the machine.
The machine which may be called a double machine is attended by two opera-
tors, and can be worked or driven by steam power, hydraulic pressure or any
other motive power capable of doing the work required.
In carrying out our invention we construct a strong metal frame, and near
the centre we mount for example a steam cylinder with its piston rod project-
ing from each end, and with means for stopping starting and reversing its
action.
The upper end of the piston rod carries a rack similarly toothed on both its
edges, and on each side of the rack is a bending block coinciding with the inside
form of the shoe.
The rack engages with a spur wheel fixed to the said frame on each side of
the rack, and upon the axles of the spur wheels, on each side of the wheel, we
fix a cam which revolves with the wheel.
The cams are in line with the bending blocks and their surfaces are shaped
to follow the configuration of the bending blocks as the latter are raised and
pass between them.
A fork or ejector is pivotted at the top of each side of the rack for the purpose
of removing the bent shoe from the block, which it does when the bending is
complete.
Shoots are provided to convey the shoes when ejected from the blocks, into the
finishing boxes on the lower part of the frame for further operation.
To the lower end of the piston rod is fixed a block or wedge having a double
incline to operate upon a series of sliding blocks carried by a ram against the
end of which the wedgelike faces of the block acts.
The finishing boxes and the sliding blocks are placed one on each side of the
vertically moving piston block, which operates on both sets at the same time.
The sliding blocks work within the finishing box and are shaped and provided
to carry out the work in rotation.
A bar of iron heated to the required degree is placed in slots above the top
bending block and below the cams and the ascending piston forces it forward,
at the same time the rack causes the wheels and cams to revolve which press the
iron bar closely to the face of the block and cause it to assume the desired form.
The ejectors come in contact with projections and push off the bent shoe, which

page_text: slides down the shoot and into the finishing box through an opening, with the
heels downwards and rests between the second and first sliding block, with the
heels just in front of a fixed crossbar preferably round.
When the action of the machine is reversed and the wedge block begins to
operate, the first and second block with the shoe between them move towards
the end of the box and the heels are forced against the round bar which bends
them at a right angle before they can pass over it, thus forming the heel bits or
calks.
If the shoes are to be "dished" the two blocks are so formed as to impart by
pressure the desired configuration.
The continued forward action of the wedge now carries the third block for-
wards, this is fitted with the nail-hole punches which pass through the second
block and are pressed into or through the shoe, and continued pressure com-
presses and thickens the heel calks.
The reverse action and receding of the wedge draws back the third block and
withdraws the punches, then the second block is withdrawn releasing the shoe
which falls by gravity through an opening in the bottom of the box into a
receiver.

Improvements in Machinery for the Manufacture of Horse Shoes.
We, JOSEPH STUART ROMANES, 101, Danville Street, City of Sheffield, Farrier,
and ALLEN BELL, of 242, Brook Hill, Sheffield aforesaid, Manager, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to the manufacture of horse shoes, and more particularly
to the machinery by which such manufacture is carried out.
The object of the invention, is the more rapid and effective manufacture of
such goods, as by our machine, two shoes are bent, shaped, heeled, dished, and
the nail-holes punched during one complete action of the machine.
A machine which carries out the abovenamed objects satisfactorily is illus-
trated in the annexed drawings, in which
Fig. 1, is a front elevation of the machine with the bending block ready to
receive the bar for the shoe, and part of the frame removed to exhibit interior.
Fig. 2, is a side elevation of same, with bending block raised.
Fig. 3, plan of same.
The machine which may be called a double machine as two similar operations
are carried on at the same time by it, is attended by two operators, and may
be driven by steam power, hydraulic pressure, or any other motive power capable
of doing the work.
We have shown in the drawings a machine constructed in the least expensive
manner, and driven direct from a main shaft MS, by means of reversing
toothed wheels and a screw action instead of by hydraulic power, or a steam
cylinder as described in the Provisional Specification.
We provide a strong metal frame A, and near the centre we mount a pair of
spur wheels B, B2, the first being mounted upon the vertical shaft carrying the

page_text: mitre wheel C, and the latter upon a screw E, which corresponds with the screw-
threaded boss of the wheel.
The handlever D, is for the purpose of stopping and starting the machine, by
throwing the wheels C², and C³, alternately in and out of gear with the wheel C,
or both out of gear as required.
It is also connected with a vertical rod D², by means of which the machine
is reversed at the end of each up and down stroke automatically.
It will be understood that when the shaft MS, is in motion, and the wheels C²
(or C³) and C, are engaged, the rotation of the spur wheel B2 will cause the
screw E, to rise or descend as the case may be.
The upper end of the screw carries a rack F, which is toothed on its opposite
edges, which engage with the teeth of two spur wheels H, H³,
Upon each side of the said rack are projecting bending blocks G, both of
which are seen in Fig. 2, these blocks coincide with the inside configuration of
the intended shoe, and upon the axles on each side of the said rack wheels H
and H, we fix the cams I, I which are so located, and their peripheries so
shaped, that they follow the configuration of the blocks G, as they are rotated
by the rise and fall of the rack and as the blocks pass between them.
Ejectors J, are pivotted at the top of the rack for the purpose of removing the
bent shoes from the blocks and passing them into vertical shoots K, down which
they slide into the finishing boxes L and L².
The ejectors are forked in shape and lie at the back of the shaping blocks;
when the shoe is bent, the upper ends of the ejectors come in contact with
inclines formed upon the frame causing the lower forked part to be moved for-
ward and push off the shoe.
Upon the lower end of the screw we fix a wedge-shaped block M, its double
inclines arranged to operate upon a series of horizontally sliding blocks N, O,
and P, carried upon arms Q, against the opposite ends of which the different
inclines of the block M, act, both sets in the boxes L, and L2, being acted upon
at the same time.
Horizontal slots R, are prepared in the frame above the top of the bending
blocks when they are at their lowest point, to receive the heated bars of iron;
when these are placed in position, the operator moves the lever D, inwards which
throws the wheel C3 into gear with C, thus causing the spur wheels B and B², to
revolve and the screw E, to ascend.
The bending blocks carry up the heated bars between the revolving cams I
and 13, which press the bars closely to the faces of the blocks and cause them to
assume the required form.
The ejectors then come into action, and push off the shoes into their respec-
tive shoots K, which conduct them with the heels downwards into the finishing
boxes where they rest between the blocks P and O, with the heels in front of a
fixed crossbar S, which is preferably round or rounded on the top.
The action of the screw E, being reversed by the withdrawal of the mitre
wheel C3, and the gearing of the wheel C2 with the wheel C, the wedge shaped
block M, descends and commences to act upon the bars Q, of the slide
blocks N, O, forcing them forward towards the opposite ends of the boxes L
and L2, and the shoe X being carried with them, the heels are turned up to a
right angle or thereabouts in passing over the crossbar S.
When the shoes are required to be "dished," the faces of the blocks O, and P,
are so formed as to impart the desired configuration by pressure.
By the continued movement of the blocks N and O, the block P, which sup-
ports the shoe X, is brought up against the end plate of the box, and the shoe
is subjected to the pressure of the block O, which compresses the heels; the
block N, then closes and punches the nail holes by means of the punches T,
which pass through holes in the block O.
;
The motion of the machine is now automatically reversed by the action of a
pin W, projecting from the wedge piece M, striking the bottom of the slot Y,

page_text: in the reversing rod D2 see Fig 2, which moves the shaft MS, and throws the
wheel out of gear, and the wheel Cinto gear with C, which reverses the
action of the screw, raising the wedge piece and drawing back the blocks N
& O.
These blocks are connected by means of the bars Q with the wedge piece M,
or they may be drawn back by balance weights or equivalent means.
The shoe X being now unsupported falls through the aperture U, made in the
box for that purpose and may either drop into a receiver, or be carried from the
machine upon an endless belt as may be preferred.
The shoots K, are either wholly or partially closed, or semitubular, to prevent
the accidental escape of the shoe either when ejected from the block or when
passing down.
We wish it to be understood that instead of the screw action driven by the
gearing hereinbefore described we may carry the double rack, and the, wedge
shaped block upon the opposite ends of a piston rod passing through a steam
cylinder, or hydraulic power may be applied instead of spur wheels and a screw.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1-In a machine for making horseshoes, the combination of a double rack F,
co-operating wheels H and H2, and cams I and I2 with a bending block G, and
ejector J for bending the bar of material into shoe form, as hereinbefore described
and shown.
2 In a machine for making horseshoes, the wedge shaped block M, in com-
bination with a finishing box L, provided with pressing and punching blocks O
and N, as hereinbefore described and shown.
3-The machine for making horseshoes, constructed and arranged substan-
tially as herein before described and shown.
