Improvements in or relating to Horse Shoes.
I, EMERICH VON MARSOVSZKY, of VI, Felsöerdösor 25, Budapest, in the King-
dom of Hungary, Engineer, 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:-
The known disadvantages of the ordinary horse-shoe fastened by a number
of nails on to the hoof have for a long time led to efforts to design a horse-shoe
which can be easily taken off and exchanged. This is necessary for many
reasons. The nailing on of a horse-shoe weakens the hoof very much, and the
horse-shoe is worn out much quicker than the hoof grows so that in nailing on
often the former holes have to be used. Most diseases of the hoof result from
the nailing on and it always requires the assistance of a man with knowledge
and experience which cannot always be obtained.
The propositions made for doing away with these disadvantages are essen-
tially of two kinds.
The first is to fasten the shoe by different means on the sides of the hoof
whilst the others manufacture the horse-shoe of two parts, one of them being
fastened on the hoof by nailing and serving to carry the part of the shoe sub-
jected to wear: both parts being connected without nails in a
they can be easily loosened one from the other.
manner that
All these propositions are merely theoretical. Their execution is opposed by
a circumstance not sufficiently taken into consideration, and which is neverthe-
less the first condition for a good horse-shoe.
In observing the step of a horse, it is found that the hoof expands sideways
in stepping, and in lifting the hoof from the ground it returns into its original
shape.
This alteration in the form of the hoof at each step is a circumstance which
requires a peculiar construction of the horse-shoe; it necessitates an elasticity
of the horse-shoe as a first condition. The horse-shoe must follow the alterations
of form or at least permit them. If this condition is not fulfilled every kind of
fastening of the shoe is equally unpractical.
The essential feature of the present invention consists that on the hoof suit-
ably formed supports are fastened in any manner such as by means of nails,
screws or cement, with which supports the horse-shoe is connected in such a
manner that without endangering the safety of this connection the hoof is per-
mitted to alter its shape without the horse-shoe following this, or the horse-shoe
is so constructed that it can follow these alterations of form.
The invention is shown in several forms in the annexed drawings.
In Figs. 1-4 a horse-shoe is represented which can follow the alteration in

page_text: the form of the hoof. In this form the horse-shoe consists of two parts con-
nected together by a pivotal joint; they are pushed one from the other when
the horse steps upon the ground, but as the foot is lifted they are returned into
their original position by a spring.
Fig. is a plan view of this horse-shoe.

1.
The horse-shoe consists of the two parts e c¹ movable round a pivot a; these
two parts c c are continually pushed one toward the other by a spring 6 placed
in a suitable hollowed portion of the part c. In front and at the sides of the
hoof, at suitable spots, supports e e¹ 2 (see Fig. 5) are fastened (in the drawing
this fastening is shown as an example by screws) provided with holes into
which catch the pins p of the projections dd influenced by the spring b
and are held fast therein. In order to prevent the parts ce from any cause, for
instance stepping on a stone or the like, being pushed too far from one another,
a screw is fixed in one of the parts reaching into the oval slot fi of the other
part. The size of this oval slot must be such that it permits the alterations of
the form of the hoof, that is the movements of the two parts e c¹ of the horse-
shoe, but prevents a too far extending movement. On the other hand, this
screw also prevents the horse-shoe from dropping off.
To enable the shoe to be removed the said screw must first be loosened and
then the two parts of the horse-shoe are distanced by means of a suitable tool
so much from one another that the pins p leave the holes p and set the horse-
shoe free from its supports. The plate covers the pivotal joint and the spring
operating it, and the whole face of the shoe (see Figs. 2 and 3).
In Figs. 6 and a horse-shoe is represented in which the projections on the
horse-shoe to be brought into engagement with the supports are subjected to
the effect of one or more springs which are intended to maintain this connection
between the projections and supports against the expanding effect of the hoof.
Fig. 6 is a plan view of this horse-shoe; Fig. 7 à section on the line E E of
Fig. 6. The projections or binding pieces are arranged on the ends of a
spring bearing against the projecting parts g g of the horse-shoe and put in
tension by means of an adjusting screw n. The spring is tensioned by said
screw so that it pushes the binding pieces with the pin p into the holes p¹
of the supports e. Care should be taken that the pin of the foremost pro-
jection catches into the suitable hole of the front support el (Fig. 7) provided
with an angular cross-piece. In order to prevent the binding-pieces from
spreading too far apart, the screw f is arranged on the horse-shoe part e, against
which the shoulder of the binding piece pushes, whilst on the part the
shoulder pushes against the wall of the horse-shoe groove before the pins ?
can leave their respective holes. If the shoe is required to be taken off it
is only necessary to loosen the screws f and in order to bring the binding
pieces out of gear with the supports e. Here also a covering plate 9 may
be used.
Whilst in these two forms the horse-shoe or parts of it follow the alteration
in the form of the hoof; in the following examples the shoe does not follow the
said alterations of form but permits the same without endangering the safe
connection between horse-shoe and hoof.
In the form shown in Figs. 8 to 11 the supports have guides in which the
shoulders of the horse-shoe parts can slide. Figs. 9 and 10 are sections
on lines F F and G G respectively of Fig. 8 and Fig. 11 is a section on line H H
of Fig. 9. As the centre line of the guides and the shoulders is in the direction
of expansion of the hoof it follows that this expansion is not hindered. The

page_text: shoe can be easily made safe against a slipping off sideways by the catch k pro-
vided with a pin i movably arranged on the horse-shoe cap d (Figs. 9 and 10)
whereby the said pin i takes into a suitable recess of the support e in front of
the hoof and thus prevents a slipping down of the horse-shoe. The catch kis
secured by any suitable safety arrangement consisting in the example shown
of a bar bent sideways and movable round its longitudinal axis. It is arranged
in the body of the horse-shoe and holds when closed, the end of the catch / by
means of its part s. In order to open the safety device the bar is taken and
its arm m turned sideways whereby its part s falls in order to set free the catch k
and after its opening the horse-shoe can be taken off sideways from the hoof.
For different sizes of the hoof and with a view to the growing of the same
the projections can be movable in the direction of length of the shoe, as
shown in the drawing by the sliding piece which is not in one piece with the
horse-shoe but is movable by means of its projection in a suitable groove of
the shoe and fastened by screws u.
The form shown in Figs. 12, 14, 15 and 16 differs from those herein before
described only in the peculiar formation of the safety device and the different
arrangement of sliding pieces. Figs. 13, 14 and 15 are sections of Fig. 12 on
lines I, I, K K and L L respectively and Fig. 16 is a section of Fig. 15 on
line R R. There the said sliding pieces are arranged on the supports e ele
fastened on the hoof, whilst the slides 68 are provided in the horse-shoe.
The cap here carries a movable catch provided with an eccentric which
latter in its locked position lies in a suitable recess in the front support piece e and
thus prevents a sliding off sideways of the shoe. The catch is here held from
opening by any suitable device. In Figs. 12, 14 and 15 the catch is provided
with a button o similar to those used on gloves; it is pushed into a suitable
opening in the front support piece e and there held tightly.
The horse-shoe may be provided with calks and toe pieces as shown in Figs. 1
Ja, and 2, the calks and the toe piece may have a W shaped section and are
inserted into the horse-shoe with their prism shaped neck pieces 22 and held
against dropping out by a shackle y.
Calks and toe pieces may also have an E like section as shown in Fig. 12,
and are secured against dropping out by a locking pin provided with an
army so that the pin, is pushed through the groove in the horse-shoe into a
suitable opening in the calk neck and the arm of the locking pin y turned
into a suitable recess in the shoe holds the calk or toe piece fast on the same.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. An improved horse-shoe having shoulders, binding or slide pieces or
grooves d, d, ², d³, d², d³, dº, d, which are brought into engagement with
support pieces e ele fastened in any suitable manner on the hoof so that the
horse-shoe either follows the alterations of the hoof or permits the same.
2. A form of horse-shoe as in Claim 1 in which two legs or parts c¹ con-
nected by a pivotal joint are constantly pressed together by a spring b the
pins p of their shoulders or projections di, de being pressed into suitable holes p¹
in the supports e¹.
3. A form of horse-shoe as in. Claim 1 in which binding pieces engaging
with the support pieces are arranged on the end of one or more springs blet
into the horse-shoe, the bending or tension of these springs maintaining the
said engagement.
4. A form of horse-shoe as in Claim 1 in which sliding pieces dor
guides are arranged with their length in the direction of expansion of the
hoof, these pieces being brought into engagement with the guides h arranged
on the supports e¹ e² or the sliding pieces ¹ respectively.

page_text: 5. A form of horse-shoe as in Claim 1 in which calks and toe pieces of Wor
E shaped section are arranged, said calks and toe pieces being held by a locking
pin, catch or the like in suitable recesses in the horse-shoe.
