I, ROBERT GEORGE DIXON, of 53 Wyndham Street, Auckland, in New Zealand,
temporarily residing at Melbourne, in the Colony of Victoria, Engineer, do hereby
declare the nature of this invention to be as follows:-
--
This invention of improvements in the construction of horse-shoes relates, first, to
the construction of what I call an "interim shoe" and, second, to the construction of
a "nailless shoe," which may be constructed either with fixed or movable treads or
calks. Both shoes are preferably constructed of malleable steel and are therefore
light and durable.
The interim shoes are intended for horses having their hoofs riddled or their walls
broken, and are secured by four nails and three dovetail side clips, such nails being
arranged at such a position as will not interfere with the quarters or sides of the
hoof, which are thus allowed to rest and grow so that they may get firm and be fit to
receive the nailless shoe.
The nailless shoe is made in two parts having a lap or hinge joint either in its
centre or at its side and is secured to the hoof by three clips which fit into suitable
incisions previously made in the wall of the hoof, the two parts of the shoe being
drawn together by a back-bolt which is arranged across the heel in order to draw the
two parts together and thus cause them to securely embrace the hoof.
In order that my invention may be well understood I will now describe it having
reference to the accompanying Sheet of drawings, which illustrates my horse-shoes
and their various parts.
Figures 1 and 2 show my interim shoe A furnished with the four holes A', the
treads A² at its bottom, and the dovetail clips A* at its top sides, one of such clips
being shewn separately in Figure 3. This shoe will not leave the hoof until taken or
worn off; while the raised treads or calks give it a firm grip.
Figure 4 shews the two parts of my nailless shoe B separated and having a lap
joint, the pin B¹ on the one half passing through the eye B₁ on the other half and so
forming a hinge. This shoe is furnished with the fixed treads B2 and dovetail
clips B, which latter are pitched and bevelled to suit the shape of the hoof. Through
77

page_text: the thick part of the heel of the shoe are the holes B*, to receive a transverse back-
bolt Bs, such as are shewn in Figures 5 and 6, by means of which bolt the clips are
caused to tightly embrace the sides of the hoof and so secure the shoe in position.
Figure 7 shews the shoe as hinged together. Figures 8 and 9 shew spanners for
screwing up the bolt. In cases where horses travel on rough ground or on tramway
motal, the back-bolt will require to be higher up from the ground and for this
purpose I secure eyes C (Figure 10) into the heels of the shoes, as shewn in Figure 4,
and pass the back-bolt through such eyes.
The nailless shoe with movable calks is shewn in Figure 11 and it is constructed
and secured to the hoof in a similar manner to the nailless shoe with the fixed calks
which is described above. The movable calks D are made preferably of steel, several
forms being shewn in Figures 13, 14, 15, 16, and 17, each having a dovetail slot D¹
formed at the bottom which fits over a corresponding dovetail projection D' on the
under-face of the shoe, as shewn in Figure 18. To secure the calks in position, I
form a threaded hole in the joint between the calk and the shoe to receive the
screw D³, as shown in Figure 11. Figure 19 shews the dovetail connection.
Before being placed in position, an india-rubber thread is placed in the dovetail slot
in the calks to prevent their shaking.
When either description of hinged shoes have been secured as described to the
hoofs, it is impossible for them to shake or be taken off without unscrewing the back-
bolt and if so desired this may be done on the termination of a journey by means
of the spanner shown in Figures 8 and 9.

page_text: I ROBERT GEORGE DIXON of 53 Wyndham Street Auckland in New Zealand
temporarily residing at Melbourne in the Colony of Victoria 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 :-
This invention of improvements in the construction of horse shoes relates First to
the construction of what I call an "interim shoe" and Second to the construction
of a "nailless shoe" which may be constructed either with fixed or movable treads
or calks. Both shoes are preferably constructed of malleable steel and are therefore
light and durable.
The interim shoes are intended for horses having their hoofs riddled or their walls
broken and are secured by four nails and three dovetail side clips such nails being
arranged at such a position as will not interfere with the quarters or sides of the hoof
which are thus allowed to rest and grow so that they may get firm and be fit to
receive the nailless shoe.
The nailless shoe is made in two parts having a lap or hinge joint either in its centre
or at its side and is secured to the hoof by three clips which fit into suitable incisions
previously made in the wall of the hoof the two parts of the shoe being drawn
together by a back-bolt which is arranged across the heel in order to draw the two
parts together and thus cause them to securely embrace the hoof.
In order that my invention may be well understood I will now describe it having
reference to the sheet of drawings which accompanied my Provisional Specification
and which illustrates my horse shoes and their various parts.
Figures 1 and 2 shew my interim shoe A furnished with the four holes A' the
treads A' at its bottom and the dovetail clips A' at its top sides one of such clips
being shewn separately in Figure 3. This shoe will not leave the hoof until taken
or worn off while the raised treads or calks give it a firm grip.
Figure 4 shews the two parts of my nailless shoe B separated and having a lap
joint the pin B¹ on the one half passing through the eye B¹ on the other half and
so forming a hinge. This shoe is furnished with the fixed treads B' and dovetail
clips B which latter are pitched and bevelled to suit the shape of the hoof. Through
the thick part of the heel of the shoe are the holes B* to receive a transverse back
bolt such as are shown in Figures 5 and 6 by means of which bolt the clips are
caused to tightly embrace the sides of the hoof and secure the shoe in position.
Figure 7 shews the shoe as hinged together. Figures 8 and 9 shew spanners for
screwing up the bolt. In cases where horses travel on rough ground or on tramway
metal the back bolt will require to be higher up from the ground and for this purpose
I secure eyes C, Figure 10, into the heels of the shoes as shewn in Figure 4 and
pass the back bolt through such eyes.

page_text: The nailless shoe with movable calks is shown in Figure 11 and it is constructed
and secured to the hoof in a similar manner to the nailless shoe with the fixed calks
which is described above. The movable calks D are made preferably of steel several
forms being shewn in Figures 13, 14, 15, 16 and 17 each having a corresponding
dovetail projection D² on the under face of the shoe as shewn in Figure 18. To
secure the calks in position I form a threaded hole in the joint between the calk and
the shoe to receive the screw D³ as shewn in Figure 11. Figure 19 shews the dove-
tail connection. Before being placed in position an india-rubber thread is placed in
the dove-tail slot in the calks to prevent their shaking.
When either description of hinged shoes have been secured as described to the
hoofs it is impossible for them to shake or be taken off without unscrewing the back
bolt and if so desired this may be done on the termination of a journey.
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
1. The interim shoe furnished with four nail holes and dovetail clips substan-
tially as herein described and explained and as illustrated in Figures 1, 2 and 3 of my
drawings.
2. The nailless shoe made in two parts hinged together and furnished with dovetail
clips and either with fixed or movable calks the two parts being drawn together by a
back bolt substantially as herein described and explained and as illustrated in the
several Figures of my drawings.
