I THOMAS DICKSON RICHARDSON, of the United Horse shoe and Nail Co, of
Cubitt Town, in the County of Middlesex Engineer and Manager of Works do
hereby declare the nature of the 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 the manufacture of horse-shoes of that kind or class
wherein the inner half or part of the shoe, that is to say, the part which supports
the inner half of the hoof, has its outer side bevelled or curved, and is gradually
diminished in thickness from the top to the bottom of the shoe, and also from the
toe to the heel thereof. The object of this peculiar formation of the shoe is to
prevent a horse from cutting the fetlock joint of one foot by striking it with the
shoe of the other foot when travelling.
$
My said invention also relates to machines for use in the manufacture of
horse-shoes.
Shoes of the kind or class above referred to have heretofore been made entirely
by hand, and considerable difficulty has been experienced in their manufacture.
My present invention is chiefly designed to provide for making such shoes either
wholly or partially by machinery, so that their manufacture is greatly simplified
and a more highly finished shoe is produced than is obtained by the method of
manufacture heretofore generally adopted.
My improved machine is designed to impart the required shape or configuration
to the straight bars or blanks, either before or after the creases and nail-holes have
been formed therein, which blanks are to be afterwards bent and finished, either
by a suitable machine or by hand.
:
My said invention is illustrated in the accompanying drawing in which
Figure 1 is a plan,
Figure 2 a side elevation, and
Figure 3 an end elevation of the improved machine.
Figure 4 is a sectional elevation, drawn to an enlarged scale, showing a roll or
swage which forms part of the said machine.
Figure 5 is a section on the line x, x Figure 4, and

page_text: Figure 7 is an underside view of a shoe of the kind hereinbefore referred to, and
Figure 8 is a section of the same on the line x³, ³.
Like letters indicate the same parts throughout the drawing.
A is a frame or table of the machine which is supported upon standards B, B¹,
C, C are standards which are firmly attached to the frame or table A and extend
upward therefrom; D is a roll or swage which is carried in bearings D¹ fitted in
slots C in the standards C. E is another roll or swage which is carried in
bearings E¹ fitted to slide vertically in the said slots C. These bearings E' are
held down by adjusting screws F, which are passed through the upper ends of the
standards C and are provided with nuts F for locking them in any desired position.
G is a toothed wheel which is fixed upon the axle of the roll D and is geared with
a pinion H¹ fixed on the driving shaft H. This shaft is carried in bearings in the
standards B¹, B. It is provided with a fly-wheel H' and with fast and loose
pulleys H³ H*. A pinion I is also fixed upon the axle of the roll D and is geared
with another pinion J fixed on the axle of the roll E.
K is a cam which is also fixed upon the axle of the roll D. L is a lever pivotted
upon a stud L¹ fixed in the standard B. This lever is coupled, by means of a
screw-bolt L, to an arm M fixed upon a shaft M¹ carried in bearings in the
standards B, B¹. An arm M is also fixed upon the shaft M¹ and is formed with a
slot M. This arm is connected, by means of a screw-bolt M, with a block N
fitted to slide to and fro in a slot A¹ in the table A. The bolt M' is passed
through the slot M³ and secured in a slot N¹ in the block N, so that the parts can
be adjusted to vary the stroke or movement of the said block. Moreover the
bolt L is passed through a slot L³ in the lever L, and the arm M is made with a
series of holes M5 for the reception of the bolt L', so that these parts can also be
adjusted for the purpose above specified. A chain or cord O is attached, at one
end, to the block N. This chain or cord is passed over a pulley O¹ carried by the
table A, and has attached, to its other end, a weight O*.
The lever L is provided with an antifriction roller L, which is held against the
surface of the cam K by the weight O' acting upon the said lever through the
medium of the block N and arms M³, M.
P, P¹ are guides, which are secured to the table A, for the purpose of guiding
the bars or blanks to the rolls. P2 is a guide for receiving and guiding the bars or
blanks as they come from between the rolls. This guide is made with a guide-
way or passage P³ (Figure 2) which corresponds in shape and approximately in
size, in transverse section, with the bars or blanks. The said guide is provided
with a spring Q secured to the same within the guide-way P³, and a spring Q¹ is
secured to the underside of the said guide. A pin Q is fitted to slide vertically in
a hole in the said guide and forms a connection between the springs O Q. These
springs are designed to press each bar or blank against the top of the guide-way P³
as it issues from between the rolls or swages and thus prevent its displacement.
-
The shoe shown in Figures 7 and 8 is of the same shape and size in transverse
section, from a to b, as the bar or blank from which the shoe was made, in this
case it is square. The other part of the shoe is gradually diminished in thickness
and correspondingly increased in height from 6 to c, and is also diminished in
thickness from the top to the bottom of the shoe, the outer side being curved or
convex as shewn in Figure 8.
The lower roll D is designed to support the blank while the roll E imparts the
required form thereto. One half of the roll E has its surface parallel with its axis;
the other half of this roll is made with a curved surface as indicated by the sections
shown in Figures 5 and 6.
In making a horse-shoe according to my said invention, I take a straight bar or
blank of the required dimensions and place it upon the table A between the block N
and the rolls D, E and then start the machine. The block N is operated by the
cam K. through the medium of the lever L and arms M, M2, and pushes the bar or
blank between the said rolls. The said blank first passes freely between the roll D
and the parallel part of the roll E. The curved part of the roll E then acts upon

page_text: the blank, which is thus gripped between the rolls. The block N, being released
by the cam K, is then moved back by the weight O³, and the blank is moved
forward by the action of the rolls. The blank as it comes from between the rolls
enters the guide-way PS and is pressed by the springs Q Q¹ against the top thereof.
While the rolls are acting upon the said blank, another blank is placed between
the said rolls and the block N.
The pressure exerted upon the blank by the rolls or swages is regulated by
means of the adjusting screws F, and should be such that the metal will be
properly compressed in the passage of the blank between the said rolls or swages.
The blank formed as above described is bent and finished by hand or in any
other convenient manner. The nail-holes and creases are formed either before or
after the blank is rolled.
I sometimes use rolls or swages differing in shape from those shown in the
drawing, according to the desired configuration of the shoes to be produced. I may
use two or more pairs of these rolls or swages with each machine, the said pairs of
rolls being made interchangeable.
By means of my improved machine I am enabled to produce a shoe of the kind
or class above described, which is a great improvement, both in shape and
appearance, upon a shoe made by hand in the ordinary manner.
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 :-
First. In a machine for the manufacture of horse-shoes, the employment of a roll
or swage, part of whose periphery is so shaped that it will impart the desired
configuration to the bars or blanks, the other part thereof being parallel with its
axis, substantially as, and for the purpose, above specified.
Second. In a machine for the manufacture of horse-shoes, the combination with a
pair of rolls or swages, of the sliding block and means for imparting to-and fro
motion thereto, substantially as, and for the purpose, set forth.
Third. The improved machine consisting of the parts constructed and combined
substantially as described with reference to the accompanying drawing and
operating as, and for the purposes, specified.
Fourth. A horse-shoe manufactured by means of my improved machine sub-
stantially in the manner above set forth.
