Improvements in Machines or Appliances for Making Horse Shoes.
I WILLIAM THOMAS HILL of 75 Moulsham Street Chelmsford in the County
of Essex Mechanical Engineer do hereby declare the nature of this invention to be
as follows:-
:―
My invention relates to machines for manufacturing horse shoes.
Horse shoes as at present made in quantities for supplying to farriers are not
usually of a regular or even curve nor flat, and consequently entail more work in
fitting than would otherwise be the case. Horse shoes having deep grooves for
rubber or similar material to prevent slipping have now to be stamped out at an
expense which tends to hinder their general adoption.
The object of my improvements is to provide machines which shall remedy the
aforesaid defects and enable both ordinary and deep grooved shoes to be made from
rolled bars at much less expense than by stamping and which machines are sub-
stantially as hereinafter described.
The main portion consists of a metal block grooved and stepped, and fitted with
a screw centre pin. A slotted lever works upon this centre pin and is fitted with
rollers, one of which works in the groove of the metal block and is thereby guided
together with the lever and other rollers in a proper course partially around one of
the steps of the block. Upon that step is laid a part of a rolled bar sufficiently
heated to bend easily and on working the lever one of the other rollers upon it
bends the bar to the desired shape, another of the rollers at the same time keeping
the bar flat upon the step. A thumb screw upon the centre pin keeps the lever at
the proper height. A recess is formed in the groove into which the first mentioned
rollers are withdrawn to allow the removal of the shoe from the step. In making
deep grooved shoes iron rods are laid in the grooves of the rolled bars and are
heated and placed in the machine together with the bars and are bent with them,
being afterwards taken out or falling out on reversing the shoe.
The heated bar when put in the machine is kept in place by a stud let in the
block, and by a fork, one end of which fits into a hole made for it in the block.
Variations may be made in the details to provide for special requirements and
for other purposes as follows:-
When it is intended to make several sizes or shapes of shoes upon one machine
the top of the block is recessed to admit of small blocks having or forming grooves
of various sizes and shapes, being placed therein, or a plate or plates of sufficient
thickness and shaped so as to form a groove when fixed, may be secured to the
block; the steps may also be made removable and of varying widths and by
changing them and the lever or one or more of the rollers several sizes of shoes of
one shape may also be made without alteration of the groove.
The block may be made with or have affixed to it a stump to fit into the holes of
the anvils or swage blocks used by farriers.
The centre pin may be bushed and also be fitted with a spring below the slotted
lever and with a nut having a cam lever thereon above it, and the slotted lever may
be raised by the said spring to allow of the removal of the shoe and lowered by the
cam lever. The lever called the slotted lever may be also forked or be forked
only and it may have an additional roller upon it to steady it by working upon the
grooved block; it may also be fitted with one or more additional rollers to assist in
bending the heated bar, and such roller or rollers may be upon the lever or upon an
arm projecting from it. The stud upon the block which keeps the heated bar in its
place may have a set screw let into it so as to secure various sized bars.
I consider the features of novelty to be the combination of grooved and stepped

therein as hereinbefore described.

COMPLETE SPECIFICATION.
Improvements in Machines or Appliances for Making Horse Shoes.
I WILLIAM THOMAS HILL of 75 Moulsham Street Chelmsford in the County
of Essex Mechanical 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 :-
My invention relates to machines or appliances for making or manufacturing
horse shoes. Horse shoes as at present made in quantities for supplying to farriers
are not usually of a regular or even curve nor flat and consequently entail more
work in fitting than would otherwise be the case. Horse shoes having deep grooves
for rubber or similar material to prevent slipping have now to be stamped out or
otherwise to be heated twice or several times in shaping at an expense which tends
to hinder their general adoption.
The object of my improvements is to provide machines or appliances which shall
remedy such defects and enable both ordinary and deep grooved shoes to be made
from rolled bars with one heating at much less expense than by stamping and by
farriers as well as by manufacturers and which machines or appliances are
substantially as described hereinafter, with the aid of the accompanying drawing
which is herein referred to by letters.
The main portion consists of a metal block, "A," made in one or more pieces and
being grooved and stepped (or having a smaller block therein which is grooved and
stepped) and fitted with a screw centre pin B. A slotted hand lever, C, works
upon this centre pin and is fitted with vertical and horizontal rollers D, E, one or
more of which vertical rollers works in the groove F of the metal block and is or
are thereby guided together with the lever and other rollers in a proper course
partially around one of the steps G of the block. Upon that step is laid a short
length of a rolled or other bar sufficiently heated to bend easily and on working the
lever one or more of the other vertical rollers D upon it bends the bar to the
desired shape, the horizontal roller or rollers E at the same time keeping the bar
flat upon the step. One or more nuts I upon the centre pin, together with a
holding down plate W, keep the lever at the proper height, or a thumb screw and
collars upon the pin may be used for the purpose without a plate. A recess I is
formed in the groove, into or through which recess the first mentioned rollers are
withdrawn to allow the removal of the shoe from the step. In making deep
grooved shoes iron rods are laid in the deep grooves of the rolled bars to preserve
their proper shape in bending and are heated and placed in the machine together
with the bars and are bent with them, being afterwards taken out, or falling out on
reversing the shoe.
The heated bar when put in the machine is kept in place by a stud, K, let in the
block and having a thumb or set screw, L, therein to admit of securing various
sized bars, or by tongs or pliers, V, or a fork, one end of which tongs or fork fits
into a hole made for it in the block.
Variations may be made in the details to provide for special requirements and
for other purposes as follows :-
:-
When it is intended to make several sizes or shapes of shoes upon one machine
the top of the block is recessed to admit of one or more small blocks, M, being
placed therein such blocks having or forming either steps or grooves, or both, of
various sizes and shapes, or a plate or plates of sufficient thickness and shaped so
as to form a groove when fixed may be secured to the blocks, and such plates may
be of varying sizes and shapes as required for various sizes and shapes of shoes ;

page_text: one or more of the steps may also be made so as to be removed separately N,
(whether in combination with the block A or the small blocks M,) thus allowing
other steps of varying widths and depths to be substituted and by changing them
and the slotted lever, or one or more of the rollers upon the lever, several sizes of
shoes of one shape may also be made without alteration of the groove.
In the same
way, or by changing the rollers only, various widths of rolled or other bars may be
used according to the width of tread of the shoe required. To facilitate changing
the rollers on the slotted lever the pins, O, upon which they work are made
removable and are secured by set screws, P, or in any other convenient method.
As many holes are provided for that purpose as may be requisite and when there
are several together, running into each other, those not in use are filled up with
fluted dummy pins, Q.
Two or more vertical rollers may be used upon the slotted lever, one or more in
the groove for guiding the lever &c. and the other or others for shaping the heated
bar.
In making shoes which are required to be wider in one part than in another the
short lengths of rolled or other bars from which the shoe is to be formed are rolled
or made of the proper section in different parts in the usual way and the groove or
grooves in the machine or appliance are of such shape as to guide the rollers in the
required curve round the outside of the bar and thus bend it to form the shoe, and
the stepped block is of the shape of the inside of it, both admitting of the changes
and variations before mentioned.
The block may be made with or have affixed to it a stump, R, of suitable cross
section to fit into the holes of the anvil or swage block used by farriers, which anvil
would then form a convenient stand for the machine.
The centre pin may be bushed with a bush or collar (of which S, is a plan), and
may also be fitted with a spring below the slotted lever, and with a nut having a
cam lever thercon above it, and the slotted lever may be raised by the said spring
to allow of the removal of the shoe and be lowered by the cam lever. For the
purpose mentioned in the next paragraph the centre pin may be fitted with a
moveable nut or head having a horizontal aperture through it.
The lever called the slotted lever may be also forked, or forked only, or it may
be made as a bar to pass through the nut or head of the centre pin mentioned in the
preceding paragraph, and such lever may have an additional horizontal roller upon
it to steady it by running upon the upper part of the grooved block A.; it may also
be fitted with one or more additional rollers T to assist in bending the heated bar
and such additional roller or rollers may be upon the lever, or upon an arm, U,
projecting from it and any of the rollers may be either flat or coned or of any other
required section.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
=
1. The combination and arrangement of the various parts before mentioned
particularly the grooved and stepped block or blocks, centre pin, slotted hand lever
with rollers, iron rods, stud and screw, holding down plate and stump and the
variations therein, substantially as and for the purposes hereinbefore described.
2. The use for the purposes aforesaid of the slotted hand lever herein described
and of the variations therein as hereinbefore mentioned.
