Improvements in Horse-shoes.
I, JOHN EDMUND JARVIS, of 39, Victoria Road, Kensington, London, W.,
Veterinary Surgeon, do hereby declare the nature of this invention to be as
follows:-
:-
L
My invention relates to improvements in horse shoes, more especially suited for
cart horses or horses used for business purposes; and has for its object to provide a
light permanent or non-wearing shoe with renewable toe and heel calks and with
an easily renewable wearing surface of wood rubber leather or other durable and
comparatively soft and elastic material which will afford a good foothold on slippery
surfaces and which as well as the other parts of the shoe can be easily adapted to
suit the foot and may be replaced when worn without difficulty.
The non-wearing or body part of the shoe consists of a thin metal plate or shoe
adapted to cover the whole of the sole of the foot including the frog, or the sole or
any part thereof exclusive of the frog.
To the under surface of this plate or shoe is secured by screw, bolt, or wedge, a
toe-plate having, in the case of shoes for horses doing heavy work, one or more
downwardly projecting pieces to form a toe-calk or calks, the toe clip being in this
case formed either on the said toe piece or by bending up a portion of the main
plate or shoe. In the case of shoes for light work, for which a toe calk is not
required, the toe clip would be formed on the renewable toe-piece. This toc-picce
besides being bolted or rivetted to the main plate or shoe may be made to interlock
therewith and in any case it is provided at its rear part with a downwardly pro-
jecting lug or lugs adapted to form one or more jaws between which and corre-
sponding downwardly projecting lugs or jaws at the heel part of the plate or shoe
is held a renewable block or plate of non-metallic material above mentioned to
constitute the wearing surface of the shoe, the jaws between which this is held
being of such form as to grip it firmly and hold it securely in place with or without
the assistance of screws or bolts embedded in said block or plate. This block or
plate covers the heads of the nails by which the main plate or shoe is secured to
the foot, so that the plate cannot work loose. The plate being thinner than an
ordinary shoe will take a much smaller nail thereby avoiding to a certain extent
the risk of pricking or binding to the sensitive parts of the foot.
In the case of a shoe whereof the metal plate does not cover the frog, this plate
or block forms a soft cushion which may be readily adapted to bring more or less
of the weight to bear on the frog as may be desirable.
In a modification, instead of a toe plate I may employ an underplate which covers
the whole surface of the shoe or iron and serves to hold in place a layer of leather,
india rubber or other material whose shape corresponds to the shoe and which is
formed with studs adapted to project through apertures in the underplate. The
underplate is secured to the iron or shoe by a heel clip and by bolts as before.

Improvements in Horse-shoes.
1, JOHN EDMUND JARVIS, of 39, Victoria Road, Kensington, London, W.,
Veterinary Surgeon, 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 improvements in horse shoes, more especially suited for
cart, omnibus, and other draught horses; and has for its object to provide a light
permanent or non-wearing shoe with renewable toe and heel calks and with an
easily renewable wearing surface of wood, rubber, leather, cork, compressed paper,
or other durable and comparatively soft and elastic material, which will afford a
good foothold on slippery surfaces, and which as well as the other parts of the shoe
can be easily adapted to suit the foot and may be replaced without difficulty.
Reference is to be had to the accompanying drawings, forming part of this
Specification; wherein
Figure 1 is a side elevation,
Figure 2 a longitudinal section,
Figure 3 an underside plan (the wearing surface at the toe being removed) and
Figure 4a top plan, of a shoe intended for heavy cart or dray horses.
Figure 5 is a longitudinal section of a somewhat lighter shoe, and
Figure 6 is an underside view of the permanent sole plate thereof, the renewable
wearing portions being removed but indicated by broken lines.
Figures 7 and 8 are similar views of a slightly modified form of the same shoe.
Figures 9 and 10 are similar views of a further modification in the mode of fixing
the wearing surfaces.
The same letters of reference indicate like parts in all the figures.
Referring to Figures 1 to 4, the non-wearing or permanent body part of the shoe
consists of a comparatively thin metal plate or shoe A which may be adapted to
cover the whole of the sole of the foot, including the frog, or the sole, or any part
thereof, exclusive of the frog. To the under surface of this plate or shoc A, which
in the present example is of the ordinary horse shoe form, is secured by screws,
bolts, or rivets a toe plate B having, in the case of shoes for horses doing very
heavy work, one or more downwardly-projecting pieces C to form a toe calk or
calks. This toe plate B may be made to interlock with the main plate or shoe A
and it is provided at its rear part with a downwardly-projecting and rearwardly
inclined lug or lugs d adapted to form one or more jaws between which and corre-
sponding downwardly and forwardly projecting lugs or jaws d' formed at the heel
part of the plate or shoe A is held a renewable block or plate D of non-metallic
semi-elastic material above mentioned to constitute the wearing surface of the shoc,
the jaws between which this block is held and the bevelled front and rear edges
of the block being of such form that it is gripped firmly and held securely in place,
both against fore and aft or lateral displacement, with or without the assistance of
screws or bolts embedded in said block or plate. This block or plate D covers
the heads of the nails by which the main plate or shoe A is secured to the foot in
the ordinary way so that the plate A cannot work loose. The plate A being
thinner than an ordinary shoe, will take a much smaller nail thereby avoiding, to a
certain extent, the risk of pricking or binding to the sensitive parts of the foot. In
the case of a shoe whereof the metal plate A does not cover the frog, this plate or
block D forms a soft cushion which may be readily adapted to bring more or less
of the weight to bear on the frog as may be desirable. The cavity of the toe
plate B, between the toe calk C and the lugs d, is filled or nearly so by another
block E of elastic or semi-elastic material, preferably rubber, cemented to a base
plate e of leather and secured in place by a nut and bolt F so as to admit of ready
replacement when worn, the bolt assisting the screws to hold the whole together.
In Figures 5 and 6, the plate A covers the whole of the sole except the frog.

page_text: The toe plate B has no calk C but has formed on it the upwardly-turned toe clip a,
which in the former example was formed on the plate A. The plate B is secured
to plate A only by the bolt F which also secures the block E in place as before.
The plate B has the lug or jaw d between which and the jaws d' at the heel of the
plate A the block D is held as before described. The slot in the plate A in
which the bolt F engages, has an enlargement at its rear end so as to admit of the
bolt being removed if desired without detaching plate A from the foot.
In Figures 7 and 8, the plate A covers the whole foot and has a clip d partly
punched out of it to hold the block D in conjunction with clip d', the two clips
being slightly out of parallel so that a tapered block may be driven tightly between
them, as is also the case in Figures 5 and 6. The plate B has the the calk C and
clips done at each side of clip d and forming extensions thereof, to assist in
holding block D in place. The plate B is secured to the plate A by bolt F, a
plate e of lead, leather, or rubber, being placed between them to form a cushion.
In Figures 9 and 10, A. is a plate covering the whole sole of the foot and G is
a plate of leather, india-rubber, or other material, corresponding in shape to the
plate A and carrying the wearing blocks or studs H of india-rubber, which project
through apertures in an underplate I of similar shape to plate A and secured
thereto by a heel clip d'and by bolts, as shewn, so as to admit of the wearing
surfaces being readily renewed when necessary.
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 ;
1. The respective combinations of parts constituting the respective arrangements
of horse-shoes with permanent plate or shoe and renewable calks and wearing
surfaces, substantially as specified.
2. The combination, with the plate or shoe A, of the renewable wearing surface D
held between clips, substantially as specified.
3. The combination, with the plate or shoe A, of the renewable toe plate and
calk screwed to the plate A, as described.
4. The combination, with the permanent plate A and the apertured underplate I
bolted thereto, of the wearing blocks H projecting through said apertures and
attached to a plate clamped between the plates A. and I, as specified.
