Improvements in Machinery for Pressing Horse Shoes and for
Forming Toe Clips thereon, and in the Method of Forming
such Toe Clips.
I, WILLIAM INCH, Superintendent at the Works of the United Horse Shoe
and Nail Company, Limited, Cubitt Town, London, do hereby declare the nature
of this invention to be as follows:
Heretofore, so far as I am aware, it has been customary, in machine-made horse
shoes, to form the toe clip by hammering-out a part of the front edge of the shoe,
the metal to form the clip being taken or drawn from the said front edge in a
manner which detracts from the wearing capability of the shoe at that part.
In
order to obviate this defect I roll the bar of metal, intended to form the shoe,
with a part projecting upwards at the point where the clip is to be formed. This
projecting, part is afterwards finished to the required shape by hammering, either
by hand, or by any suitable machinery such as that, for example, which I will now
proceed to describe.
The said machinery consists, firstly of devices for pressing the horse shoes after
they have been bent to shape, and secondly of devices for hammering-out the
aforesaid projecting part on the toe of the shoe in order to form the clip, while
the shoe is being pressed and held by the pressing devices.
The pressing devices consist of a pair of dies between which the redhot shoe is
placed and pressed. The lower of the two dies is mounted on a crosshead, frame,
or slide, which is free to move up and down in suitable guides provided in or on
the framing of the machine. This crosshead, frame, or slide, with the lower die
mounted on it, is actuated by means of a cam, eccentric, or other suitable
mechanical device, or by hydraulic or other power acting directly or indirectly
thereon. The lower die has in its front edge a recess to receive the abovementioned
projection formed on the front of the shoe. The upper die is mounted on a second
crosshead, frame, or slide, which is also free to move up and down in guides in or
on the framing of the machine, but is pressed downwards by means of springs or
otherwise so as to offer sufficient resistance to the upward motion of the lower die
to enable the two dies to hold the shoe firmly in position between them while the
hammering-out of the clip is effected, and in some cases to offer also sufficient
resistance to enable the two dies to impart the required pressure to the shoe.
The devices for hammering-out the clip are placed in front of the pressing dies
holding the shoe and consist preferably of revolving hammers of the kind described
in the Specification of a Patent granted to W. R. Lake, dated 23rd December
1873, No. 4210, but they may consist of any other suitable kind or arrangement of
hammering mechanism.
The action of the aforesaid machinery is as follows:-The two dies being
separated or opened, a red hot shoe is placed on the lower die with the projection
intended to form the toe clip lying in the hollow on the front edge of the said die.
This die is then moved upwards, pressing the shoe against the upper die and
carrying the aforesaid projection on the toe of the shoe past the revolving hammers
which act upon and draw out the said projection so as to form the toe clip without
drawing any metal from the front lower edge of the shoe which is left intact, and
as sharp as any other part of the lower edge. If desired, the crosshead, frame, or
slide, carrying the upper die, may come against suitable stops to arrest its upward

page_text: motion just before the lower die has reached the highest point of its movement,
whereby a final squeeze or nip is given to the shoe. The dies then descend and
open, and the shoe that has been pressed and has had the toe clip formed où it is
taken out and a fresh one inserted.
The same machinery may be employed for forming the toe clips out of the metal
at the toe of the shoe in the manner already practised, that is to say without the

special projecting part rolled on the bar as above described.
cases hammering mechanism may be dispensed with and the toe clip be hammered,
out by hand while the horse shoe is held between the dies of the press.
The above description applies to a machine in which the dies move vertically
but it is obvious that such a machine may be arranged so that the dies move
obliquely or even horizontally.

Improvements in Machinery for Pressing Horse Shoes and for
Forming Toe Clips thereon, and in the Method of Forming
such Toe Clips.
I, WILLIAM INCH, Superintendent at the Works of the United Horse Shoe
and Nail Company Limited, Cubitt Town, London, do hereby declare the nature
of the said invention, and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement that is
to say:-
Heretofore, so far as I am aware it has been customary, in machine made horse
shoes, to form the toe clip by hammering-out a part of the front edge of the shop,
the metal to form the clip being taken or drawn from the said front edge in a
manner which detracts from the wearing capability of the shoe at that part.
In order to obviate this defect I roll the bar of metal intended to form the
horse shoe, with a part projecting upward at the point where the clip is to be
formed. This projecting part is afterwards finished to the required shape by
hammering, either by hand, or by any suitable machinery such as that, for
example, which I will now proceed to describe with the aid of the accompanying
two sheets of drawings in which,
Figure 1 is a side elevation, Figure 2 a plan, Figure 3 a longitudinal sectio
taken on the line 1. 1. of Figure 2 and Figure 4 a front elevation of a pressing
and hammering machine with my improvements applied thereto.
Figures 5, 6 and 7 are respectively a plan, side elevation, and end view to
a larger scale than Figures 1 to 4 of the lower or movable die used in the
machine.
Figures 8 and
top and underside views respectively of so much of the rolle l
bar herein before referred to as comprises a blank for making one horse shoe,
and Figure 10 a cross section of such bar taken on the line 2-2 of Figures 8
and 9.
Figures 10, 11 and 12 show a modification of the hammering device and die
to meet the requirements of making horse-shoes with double clips.
Similar letters of reference relate to like parts in all the figures of the
drawings.
The said machinery consists, firstly of devices for pressing the horse shoes after
they have been bent to shape and secondly of devices for hammering out the

page_text: aforesaid projecting part on the toe of the shoe in order to form the clip, while the
shoe is being pressed and held by the pressing devices.
A, A are the side frames of the machine tied together by stretchers B.
This
The pressing devices consist of a pair of dies C, C¹ between which the red-hot
shoe is placed and pressed. The lower of the two dies C, is mounted (removably
by preference) on a crosshead frame or slide D which is free to move up and
down in suitable guides E, provided in or on the frames A of the machine.
crosshead frame or slide D with the lower die C mounted on it, is actuated by
means of a cam F acting preferably against a friction roller G, turning in bearings
secured to the lower end of the frame D. Instead of a cam an eccentric or other
suitable mechanical device may be employed, or the frame or slide D may be
actuated by hydraulic or other power acting directly or indirectly thereon. The
lower die C, has in its front edge a recess C2, to receive the above mentioned
projection formed on the front of the slide. The upper die C is mounted and
preferably fixed rigidly on the underside of a second crosshead, frame or slide H,
which is also free to move up and down in guides I, in or on the frames A of the
machine, but is pressed downwards by means of springs J or otherwise so as to
offer sufficient resistance to the upward motion of the lower die C, and crosshead,
frame or slide D carrying it, to enable the two dies C, C¹, to hold the shoe C³
firmly in position between them, while the hammering-out of the clip is effected,
and in some cases to offer also sufficient resistance to enable the two dies to impart
the required flattening or straightening pressure to the red-hot shoe.
The devices for hammering out the clip are placed in front of the pressing
dies C, C holding the shoe and consist preferably of revolving hammer of the
kind described in the Specification of a Patent granted to W. R. Lake dated
23rd December 1873 No. 4210. Hammering devices of this kind are shown in
Figures 1, 2, 3, 4, 10 and 11 of the drawings accompanying this Specification but
any other suitable kind or arrangement of hammering mechanism may be employed
if preferred. The hammering devices shown in Figures 1, 2, 3 and 4 consist of
circular hammering rollers K, mounted loosely on pins L, which secure them
between two discs or plates M, M, fixed on the shaft N which may be driven
direct by a belt applied to the fast and loose pulleys O, O¹ on the said shaft or by
intermediate gear not shown in the drawings from the first motion shaft P rotated
by the strap pulley Q. This shaft P imparts motion to the crosshead D by means
of the toothed pinion Q' secured on the shaft P, toothed spur wheel R' secured on
the intermediate shaft R, toothed pinion R², on the said shaft R, and toothed
wheel S¹ secured on the shaft S, which carries the cam F.
In the arrangement shown in Figures 1, 2, 3 and 4 the pinion R2 is loose on the
shaft R but can be connected so as to rotate therewith when required by means of
the sliding clutch R³. This clutch arrangement enables the movement of the
crosshead D and die C to be stopped at any time without stopping the first
motion shaft P.
The action of the above described machinery is as follows:-The two dies C, C'
being separated or opened as shown in Figure 3, the red hot shoe C³ is placed on
the lower die C with the projection T intended to form the toe clip laying in the
hollow or recess C2 on the front edge of the said die. The crosshead, frame or
slide D with the die C upon it, is then raised by the cam F and presses the shoe C³
against the upper die C and then carries the shoe with the projection T on the
toe thereof past the hammers K which revolve with the discs or plates M, M in the
direction of the arrows in Figures 1 and 3, the edges of the discs K acting upo..
and drawing out the said projection and hammering it into the recess C², so as to
form the toe clip without drawing any metal from the front lower edge of the shoe,
which is left intact and as sharp as any other part of the lower edge. If desired.
the crosshead, frame or slide, carrying the upper die C¹ may come against suitable
stops to arrest its upward motion just before the lower die C has reached the
highest point of its movement, whereby a final squeeze or nip can be given to the
shoe. The cam F then allows the crossheads D, H and dies C, C' to descend and

page_text: .
open and the shoe C³ that has been pressed and has had the toe clip formed on it
is taken out and a fresh one inserted. I have found it convenient to arrange the
lower die C¹ so that it can be withdrawn by the handle U or otherwise from the
top of the crosshead D onto the table V, where it rests while the shoe is being
picked off the die by tongs or otherwise and a fresh one put in place. The die is
then again slid forward towards the hammers between the guide V₁ until it comes
against stops V2 at the ends of the guides V. By this means the crosshead or
frame D may be kept constantly in motion while the shoes are being placed in and
removed from the die C without fear of the machinery being broken by reason of
the displacement of a shoe in the die and the impossibility of getting it properly
placed before the dies close, as may happen when the shoe has to be inserted into a
die fixed to the crosshead, and during the time of opening and closing the dies.
The hind shoes of a horse are sometimes provided with two toe clips, that is to
say a toe clip on either side of the centre of the toe of the shoe; for this purpose
it is necessary to roll the bar with two projections instead of one and to deal with
these two projections I employ the modifications illustrated in Figures 10, 11
and 12 that is to say. I construct the hammers of rollers K mounted on pins L
and between discs or plates M M as above described with reference to Figures 1, 2,
3, and 4 but between each pair of discs K, I interpose a distance piece or
collar K and I bevel the rollers K as shown in Figure 10 so that when rotating,
the hammers take effect on both clips of the shoe placed on the die C shown in
Figure 12.
The angle to which the rollers K are bevilled corresponds with the angle at
which the clips are placed with reference to the centre line of the shoe. The die
shown in Figure 12 is of similar construction to that shown in Figures 3, 5, 6,
and 7 but is provided with two hollows or recesses C2, and is shaped at the front
to suit the hammers and the angle at which the toe clips are to be provided.
As there is considerable wear and tear on the part of the die where the recess
or recesses C² are situated, I have found it advisable to make each recess in a
separate piece of steel C4 let into the body of the die; this piece of steel can be
easily renewed when the recess C2 in it has become inserviceable.
The same machinery may be employed for forming the toe clips out on the metal
at the toe of the shoe in the manner already practised, that is to say without the
special projecting part rolled on the bar as above described. Furthermore, in
some cases, hammering mechanism may be dispensed with and the toe clip be
hammered out by hand while the horse shoe is held between the dies of the press.
The above description applies to a machine in which the dies move vertically
but it is obvious that such a machine may be arranged so that the dies move obliquely
or even horizontally.
As herein before stated Figures 8, 9, and 10, of the drawings illustrate part of a
bar of metal intended to be formed into a shoe with a part T rolled thereon and
projecting upwards from the upper side of the bar, such part being intended to
form the toe clip by subsequent hammering out to the required shape, in order to
avoid drawing the metal to form such clip from the front edge of the shoe as above
described. Figures 8 and 9 illustrate so much of such a rolled bar, after the nail
holes have been punched in it, as is necessary to form a horse shoe when bent into
the proper shape.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. Rolling the bars intended to form horseshoes with one or more projecting
parts, such as T in Figures 3 8, 9 and 10 of the drawings, such parts being adapted
to form the toe clip or clips, substantially as described.
Second. In machinery for pressing horse shoes and forming the toe clip or clips
thereon, the die C mounted on a moving crosshead frame or slide D, and a die C
mounted on a crosshead or slide H which is pressed towards the crosshead frame or

page_text: slide D by a yielding pressure such as by springs J for example, combined and
operated substantially as described with reference to the drawings.
Third. In machinery for pressing horse shoes and forming the toe clip or clips
thereon, dies for pressing and holding the horse shoes while being operated upon,
hammering devices for hammering out the clip or clips, and mechanism for moving
the said dies, so as to present the shoe contained therein to, and remove it from
the action of the hammers, and for opening and closing the said dies, combined,
arranged, and operating substantially as described with reference to the drawings.
Fourth. Machinery for pressing horse shoes and forming the toe clips thereon
constructed and operating substantially as described.
