PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Making Horse-shoes and other
Articles of similar Forms.
1, HENRY THOMPSON of 96 and 98 Sherwood Street, in the Town and County of the
Town of Nottingham, Smith and Machinist, do hereby declare the nature of this
invention to be as follows:-
My invention consists of an apparatus for the production of horse-shoes and similar
forms from bars or rods of steel or other metals at one operation, and comprises a
combination of a gripping vice, a cain moving on a spindle attached to a plate, and a
friction roller rotating on a pin, which pin is capable of adjustment by means of a slot
in the plate.
The action of my apparatus is as follows:-
A piece of rod or bar sufficient to form a horse-shoe or other shape, is heated in a
suitable forge or furnace, and when hot, one end is gripped by the vice attachment,
the other end projecting past the roller; the cam, of a proper shape to form the
the required contour of horse-shoe or other article, is then rotated, by means of a
lever, on its axis or pin, when the piece of iron, being prevented from longitudinal
movement by the gripping vice, is forced or stretched round the cam, the roller
assisting in keeping it to its shape and permitting the metal to be stretched in its
centre portion, owing to one end being gripped by the vice and the other free.
will be seen that any form of horse-shoe, from any section of metal, can be rapidly
formed, and when finished is thinner in section in the middle than at the ends, which
condition is requisite for the formation of a good horse-shoe.
It
The whole operation of bending and stretching is rapidly done, whilst the metal is
at a proper and equable temperature, so that the most difficult sections_can_be_
manipulated; which is not the case with hand made shoes, in fact it is quite impossible
to form a horse shoe from some sections of iron by hand.
My improved apparatus can be fixed to an anvil or ordinary vice, the pin carrying
the former cam being adapted to that purpose.
The shape of the forming cam and roller govern the shape of the finished shoe,
whilst the jaw of the gripping vice is made to suit the section of iron or other metal
used.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Making Horse-shoes and other
Articles of similar Forms.
I, HENRY THOMPSON of 96 and 98 Sherwood Street, in the Town and County of
the Town of Nottingham, Smith and Machinist 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 :-
My invention consists of an apparatus for the production of horse shoes and other
articles of similar forms from bars or rods of steel or other metals at one operation
and comprises a combination of a gripping vice, a cam moving on a spindle attached
to a base plate and a friction roller rotating on a pin, which pin is capable of
adjustment by means of a slot in the plate.
The invention is illustrated in the accompanying drawing which represents a
perspective view of the apparatus.

page_text: a represents the moveable jaw of a gripping vice which is operated by means of the
screw b, c is a forming cam which is made of the proper shape to form the required
contour of horse shoe or other article of similar form; this cam is mounted on a
spindle attached to a carrying or base plate e and is provided with a handle by
which it may be rotated, is a friction roller capable of rotation on a pin g which is
adjustably fixed in a slot e' in the base plate e.
The part of the cam c opposite the moveable jaw a of the vice acts as the fixed jaw.
I preferably form the came with three different faces to produce as may be desired
three different sizes of horse shoe or other article of similar form and I construct the
moveable jaw a of the vice, and the friction roller with three different bearing
surfaces to act in combination with the three different faces of the cam as is clearly
represented in the drawing.
The arm carrying the moveable jaw is fixed rigidly with the cam and moves with it
around the spindle d. The bar h represented in the drawing as having been partially
bent into the form of a horse shoe is formed with a plain outer face and a corrugated
web or body this shaped bar would be very difficult if not almost impossible to work
by hand into a horse shoe, but can be readily manipulated by the aid of my improved
apparatus.
The action of my apparatus is as follows:-A piece of rod or bar h of length
sufficient to form a horse shoe or other shape, is heated in a suitable forge or furnace,
and when hot, one end is gripped by the vice attachment a, the other end projecting
past the roller, the cam c, of a proper shape to form the required contour of horse
shoe or other article, is then rotated by means of the lever c', on its axis or pin d,
when the piece of iron being prevented from longitudinal movement by the gripping
vice a, is forced or stretched round the cam c, the roller f assisting in keeping it to its
shape and permitting the metal to be stretched in its centre portion owing to one end
being gripped by the vice a and the other free. It will be seen that any form of
horse-shoe from any section of metal, can be rapidly formed and when finished is
thinner in section in the middle than at the ends, which condition is requisite for the
formation of a good horse-shoe.
-
The whole operation of bending and stretching is rapidly done whilst the metal is
at a proper and equable temperature, so that, the most difficult sections can be
manipulated, which is not the case with hand made shoes, in fact it is quite impossible
to form a horse shoe from some sections of iron by hand."
My improved apparatus can be fixed to an anvil or ordinary vice the leg or pin e²
projecting from the base plate e being capable of fitting the square hole of an ordinary
anvil or of being held between the jaws of an ordinary vice. The shape of the
forming cam c and roller govern the shape of the finished shoe, whilst the jaw a of
the gripping vice is made to suit the section of iron or other metal used.
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
1. In apparatus for making horse shoes and other articles of similar forms the
combination of gripping vice, rotating forming cam, operating handle and adjustable
friction roller arranged and operated substantially as herein shown and described.
2. In apparatus for making horse shoes and other articles of similar forms the
combination of a rotating forming cam and gripping vice for holding the length of
metal with a friction roller, to force or bend the length of metal around the forming
cam, substantially as herein shown and described.
