An Improved Mode of Producing Non-slipping Horse-shoes.
I, JONATHAN MASON of 15 Barbican in the City of London, Builder, do hereby
declare the nature of this invention to be as follows:-
:-
This invention relates to a non-slipping horse-shoe, and the invention consists in
the mode in which such non-slipping horse-shoe is produced.
In carrying out this invention, I form in the iron blank, and round the holes, a
recess, in which I place a plug or collar of lead, or any other suitable nou-slipping
material, and I secure these plugs in position, partly by means of the ordinary
nails, which are driven through the plugs or collars, as well as through the iron.
The nails will be driven home, so that the head of the nail will be flush, or even
slightly below the surface of the non-slipping material, which may be flush with
the iron, or projecting slightly beyond it.
The recesses are formed by means of a specially shaped punch, for a certain
depth, with vertical sides, and then for a further depth conical or taper, or they
may be made conical or taper only, without the vertical portion.
When punching the recesses in the blank, the metal has a tendency to bulge out,
both on its inner and outer edge opposite each recess, which, if left, would have an
unsightly appearance.
I therefore hammer down these bulges in the usual manner, which has the effect
to slightly cant the vertical side walls of the recess inward, and give a slight
dovetail section to the recess, which serves also to retain the lead plug in position,
the lead being hammered well down into the recesses, so that it will spread out
therein.
I would here remark that I am aware lead has been combined with the metal
shoes in many ways, to produce a non-slipping horse shoe, but the irons have had
to be specially formed for the purpose. So far as I can ascertain, the present
invention for the first time puts it within the power of any ordinary farrier who
makes his own horse shoes, to produce a non-slipping shoe.
Dated this 20th of February 1894.

I JONATHAN MASON of 15 Barbican, in the City of London, Builder, 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:-
This invention relates to a non-slipping horse-shoe, and the invention consists in
the mode in which such non-slipping horse-shoe is produced.
In carrying out this invention, I form in an ordinary iron blank, and round the
nail holes, recesses in which I place plugs or collars of lead, or any other suitable
non-slipping material, and I secure these plugs in position, partly by means of the
[Price 8d.1

page_text: ordinary nails, which are driven through the plugs or collars, as well as through
the bottom plates of the recesses in the iron, and partly by the overhanging walls
of the recesses, which shape is ultimately given to the recesses.
The nails will be driven home, so that the head of the nail will be flush with, or
even slightly below the plane of the surface of the non-slipping material, which
may be flush with the iron, or projecting slightly beyond it.
In the accompanying drawing,-
Fig. 1 is an underside plan view of a horse-shoe immediately after the recesses
have been formed,
Fig. 1 being a cross section on the line x x of Fig. 1.
Fig. 2 shews an underside plan view of the horse-shoe, when it has been
completely shaped ready to be secured to the hoof,
Fig. 2 being a cross section on the line, Fig. 2; and
Fig. 3 shews a corresponding view of the horse-shoe with the non-slipping plugs
in position.
A represents the shoe iron or blank; B are the recesses, of about two-thirds of
the depth of the iron. C are the non-slipping plugs, and D the nails.
The recesses B, which are preferably rectangular, are formed in the iron blank A
by means of a specially shaped punch, that is to say, for a certain depth with
vertical sides, the remaining portion being conical, taper, or splayed out, as
indicated at Fig. 1ª.
When punching the recesses in the blank, the metal of the blank has a tendency
to bulge out, both on its inner and outer edge, opposite each recess, as indicated in
Fig. 1, which bulges, if left, would give an unsightly appearance to the shoe.
I therefore hammer down these bulges, or shape the shoe in the usual manner
(see Fig. 2), in doing which, the vertical side walls of the recess are slightly
canted inwards, so as to give a slight dovetail section to the recess (as shewn at
Fig. 2). The overhanging walls thus produced serve, in addition to the ordinary
nails, to retain the lead plug in position, the lead being hammered well down into
the recesses, so that it will spread out therein, and catch under the sloping side walls.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I would here remark that I
am aware lead plugs have been combined with the metal shoes to produce a non-
slipping horse-shoe, and I therefore make no claim to the general application of
lead plugs as a non-slipping surface to horse shoes. I am also aware that these
lead plugs have been held in the shoe by giving to the holes in which the plugs
are inserted, a dovetail or double dovetail shape in cross section, and I therefore
make no claim to the general use of dovetail-shaped holes to secure the plugs in
the shoe, but what I do claim is :-
:-
1. Forming in an ordinary iron horse-shoe blank, with a suitable punch, recesses
of about two-thirds the depth of the iron, and to which a slight dovetail shape is
subsequently given, and inserting therein plugs of lead or other suitable non-
slipping material, which are secured partly by the ordinary nails, and partly by
the overhanging walls of the recesses, as herein shown and described.
2. The mode of forming dovetail-shaped recesses in an ordinary iron horse shoe
blank, as herein shown and described.
3. The mode of producing non-slipping horse-shoes, which consists in forming
recesses in an ordinary shoe blank, inserting lead plugs therein, and securing the
same by the nails used to attach the shoe to the hoof, substantially as herein shown
and described.
Dated this 31st day of October 1894.
