IMPROVEMENTS IN HORSE-SHOES
Year: 1872

page_text: LETTERS PATENT to Robert Mudge Marchant, of Kirby Street,
Hatton Garden, in the County of Middlesex, Civil Engineer, and
Benedict John Angell, of Lubenham, in the County of Leicester,
Gentleman, for the Invention of "IMPROVEMENTS IN HORSE-SHOES."
Sealed the 1st November 1872, and dated the 4th May 1872.
PROVISIONAL SPECIFICATION left by the said Robert Mudge Marchant
and Benedict John Angell at the Office of the Commissioners of
Patents, with their Petition, on the 4th May 1872.
We, ROBERT MUDGE MARCHANT, of Kirby Street, Hatton Garden, in
the County of Middlesex, Civil Engineer, and BENEDICT JOHN ANGELL,
of Lubenham, in the County of Leicester, Gentleman, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN HORSE-SHOES," to
be as follows :-
Our Invention relates to the construction of horse-shoes with a groove

page_text: rubber (or other elastic material), which rubber by projecting below the
metal portion of the shoe forms the bearing surface or part of the
bearing surface, and thereby prevents the horse slipping, more par-
ticularly on asphalte and other pavements. And our Invention consists
in so forming the groove and the strip of india-rubber that the latter can
be readily removed when worn out, and a new strip readily substituted
without taking off the shoe. For this purpose we employ a strip of
rubber, the sectional shape of which is a segment of a circle, and we
curve the sides of the groove to correspond with the curve of the rubber,
the rubber being allowed to project below the metal portion so as to
form the surface upon which the weight of the horse first comes. To insert
the rubber strip one side of the segment is inserted in the groove, and
the other side is then compressed with a pointed tool and made to enter
the groove; the rubber strip being now in place fills the groove and
cannot come out accidentally. To remove it a pointed tool is pushed
under it at one end, so that the segment of the circle is hollowed, and the
edges consequently come towards each other till they are clear of the
sides of the groove.
In moulding the india-rubber strips it may be
desirable to place metal filings, grit, or other suitable material in the
mould, which material will become united to or mixed with the rubber
and act as a roughing to the surface thereof.
.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Mudge Marchant and Benedict John
Angell in the Great Seal Patent Office on the 4th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ROBERT 2
MUDGE MARCHANT, of Kirby Street, Hatton Garden, in the County of
Middlesex, Civil Engineer, and BENEDICT JOHN ANGELL, of Lubenham,
In the County of Leicester, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of May, in the year of our Lord 30
One thousand eight hundred and seventy-two, in the thirty-fifth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said Robert Mudge Marchant and Benedict John Angell,
Her special licence that we, the said Robert Mudge Marchant and

page_text: Benedict John Angell, our executors, administrators, and assigns, or
such others as we, the said Robert Mudge Marchant and Benedict John
Angell, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN HORSE-SHOES," upon the condition (amongst others) that
we, the said Robert Mudge Marchant and Benedict John Angell, our
executors or administrators, by an instrument in writing under our, or
one of our or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
•
NOW KNOW YE, that we, the said Robert Mudge Marchant and
Benedict John Angell, do hereby declare the nature of our said Inven-
tion, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof,
reference being had to the accompanying Drawings, that is to say :—
Our Invention relates to the construction of horse-shoes with a groove
on the under side of the shoe to receive a strip of vulcanized india-rubber
(or other elastic material), which rubber by projecting below the metal
portion of the shoe forms the bearing surface or part of the bearing
surface, and thereby prevents the horse slipping, more particularly on
asphalte and other pavements. And our Invention consists in so forming
the groove and the strip of india-rubber that the latter can be readily
removed when worn out and a new strip readily substituted without taking
off the shoe, while the strip cannot come out accidentally when in use.
The manner in which our Invention may be carried into effect is as
follows: We employ a strip of rubber, the sectional shape of which is
a segment of a circle, and we curve the sides of the groove in the shoe
to correspond with the curve of the rubber, the rubber being allowed to
project about one-sixteenth of an inch more or less below the metal
portion, so as to form the surface upon which the weight of the horse
first comes; the bearing surface may either consist of the under side of

page_text: the rubber segment, or, as we prefer, of a flat or other shaped portion
moulded with the segment.
To
Figure 1 of the annexed Drawings is a view of the under side of a fore
shoe constructed according to our Invention; Figure 2 is a section of the
same through the line a, b; and Figure 3 a section through one of the
nail holes; these holes are tapered to receive the heads of the nails so
that they may not project below the holes; Figures 4 and 5 are re-
spectively views of the under side of the "off" and "near" hind shoes;
and Figures 6 and 7 are sections of the same through the lines a, b.
In none of these Figures is the strip of india-rubber or elastic material
shewn, except in Figure 2. Figure 8 is a view of the under side, and
Figure 9 is a section of the india-rubber strip. It will be seen that its
sectional form is that of a segment of a circle, with the addition of a flat
portion to form the bearing surface, and that the sides of the groove in
the shoe are curved to correspond with the curve of the rubber.
insert the rubber strip one side of the segment is inserted in the groove,
and the other side is then compressed with a pointed tool and made to
enter the groove; the rubber strip being now in place fills the groove,
and cannot come out accidentally. To remove it a pointed tool is pushed
under it at one end, so that the segment of the circle is hollowed, and
the edges consequently come towards cach other till they are clear of the
sides of the groove. In moulding the india-rubber strips it may be
desirable to place metal filings, grit, or other suitable material in the
mould, which material will become united to or mixed with the rubber,
and act as a roughing to the surface thereof; or a roughing may be
obtained by passing pins through the rubber, as seen in Figures 8 and 9;
the heads of these pins bearing upon the top of the groove in the metal,
so that when the rubber becomes compressed by the weight of the horse
the points of the pins will project to a distance equal to the compression
of the rubber, and so that the points are withdrawn on the lifting of the
horse's foot, the action resembling that of the claws of a cat.
And having now described the nature of our said Invention, and in
what manner the same is to be performed, we declare that we do not
claim generally the construction of horse-shoes with a groove on the
under side to receive a strip of elastic material, nor do we claim generally
the employment of elastic material fitted into horse-shoes, so as to project
therefrom and form the bearing surface; but what we do claim is, the

page_text: employment in horse-shoes of strips of elastic material of such sectional
shape, and the formation of grooves in shoes of such corresponding shape
that the strips can be readily inserted in the grooves and removed when
worn out while the shoes are on the horse's feet, substantially as herein-
before described.
In witness whereof, I, the said Robert Mudge Marchant, on behalf
of myself and the said Benedict John Angell, have hereunto set
my hand and scal, this First day of November One thousand
eight hundred and seventy-two.
