COMPLETE SPECIFICATION.
Improvements in and connected with Nail-less Horse Shoes.
1, ROLAND D'ANVERS of Hastings, in the Provincial District of Hawke's
Bay, in the Colony of New Zealand, Settler, 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 nail-less horse shoes and to means for attaching such
shoes to the hoofs of horses and mules.
According to these improvements the shoe plates are connected to the hoof by
means of specially constructed toe and heel straps and by suitably shaped heel
plates. In addition, I may employ for the same purpose, toe spikes which are
arranged to penetrate the substance of the hoof, and when desired, toe and heel
calks or frost cogs may also be added.
I will describe my said invention with reference to the accompanying drawings
in which
Figure 1 is a side view of a horse's hoof with my improved horse-shoe attached.
Figure 2 is a plan of the horse shoe and its attachments.
Figure 3 is a side view of the toe strap or clip.
Figure 4 is a front view of the same.
Figure 5 is a side view of one of the heel straps.
Figure 6 is a front view of the same.
Figure 7 is a side view of an elastic packing.
Figure 8 is a section of the same.
Figure 9 is a section of one of the heel plates taken through the line A B
Figure 2.
Figure 10 is a section of the same taken through the line D C Figure 2.
Figure 11 is a side view of one of the toe spikes.
Figure 12 is a front view of the same.
Similar letters of reference indicate like parts in all the figures.
a, represents the shoe plate having a plain upper and under surface, except
that the ends of the upper surface may be slightly bevelled for a purpose to be
hereinafter described. This shoe plate has six perforations s' for the passage of
the bolts or rivets by which the accompanying parts are attached.
b, is the toe strap or clip having a broad foot by which it is attached to
the front of the shoe plate (as shewn in Figure 2) by means of screws ³ which
have their upper ends so shaped as to form toe spikes. At the upper ends of
this strap or clip is formed an eye or hook 64 to receive the screw b³.
cc, are the heel plates which rest upon the ends of the shoe plate a, and are
fastened to the upper surface of the same by screws or rivets c¹ c². These heel
plates are so formed as to project upwards on both sides so as to clip the outer
wall of the hoof, and also the inside of the bar at the same time that they also
project upwards at the back of the heel.
2, is a lug projecting upwards and fitting to the contour of the hoof; it has a
hole to receive a screw or rivet. The ends of the shoe on their upper
surface are (by preference) slightly bevelled to receive the heel plates c, but it
will be evident that they can be formed on the shoe plate itself provided always
that the walls of the heel plate are of such a thickness as to be readily bent
and bedded so as to form abutments to prevent the hoof working backwards out of
the shoe by the action of the horse.
dd, are half bands having holes d' through which they are attached by a
suitable rivet to the heel plates as shewn hy Figure 1. They extend around the hoof
and are fitted with ears or lugs ² through which the screw 6 passes, clipping

page_text: them firmly on either side of the eye or hook 6.
The ears or lugs d' are
shewn riveted on with rivets d³ but can be made in one piece with the half
bands if desired. These bands I prefer to make of copper or a metal which can be
readily bedded to the correct form of the outside of the hoof.
e, is a packing of indiarubber placed underneath the half bands d to give elasticity
and to allow of the half bands being more readily bedded to the hoof with an equal
bearing, and without undue pressure.
These packings I prefer to make with flanges e¹ so as to form a groove e² in which
the half bands are encased, and I also prefer that these be cemented to the said
bands.
b
33, are spikes with screwed ends to unite the foot 61 of the front strap 6 firmly
to the shoe plate, they are shaped at their upper ends to a chisel shaped form
so as to enter the hoof behind the hard part of the shell.
These upper ends I prefer to be bevelled at the front so as to correspond
with the angle of the front of the hoof, and to be perpendicular at the back as
shewn.
fff, are toe and heel calks held in position by the projections fl which are let
into the shoe plate and secured by the screws or bolts c' and 63. These calks can
easily be renewed when worn, or a false shoe may be fixed on by the screws c¹
and which can be readily replaced when worn in consequence of the easy
removal of the shoe proper. In winter, frost cogs may be substituted for the
calks.
In nailless horse shoes, the difficulty has hitherto been to keep the shoes firmly
in place without unduly straining the hoof or causing undue pressure or injury;
and I have found that the pressure on the toe when the horse is moving quickly
causes a backward tendency of the hoof, so that the heel gradually works itself
upwards and outwards, and thus the shoe becomes loose. These defects are
prevented by the elasticity of the packing e, and the form of the heel plates c.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a nailless horse shoe the combination with the shoe plate a of the heel
plates c, the half bands d, the front strap b, and the screw 6, substantially as
hereinbefore described and as illustrated by the accompanying drawings.
2. In a nailless horse shoe, the combination with the shoe plate a of the heel
plates c, the half bands d, the front strap b, the spikes 6, and the screw ³,
substantially as described and as illustrated by the accompanying drawings.
3. In a nailless horse shoe the combination with the shoe plate a of the heel
plates, the half bands d, the elastic packings e, the front strap b, and the
screw, substantially as described and as illustrated by the accompanying
drawings.
4. In a nailless horse shoe, the combination with the shoe plate a, of the heel
plates c, the half bands d, the front strap 7, the screw, the elastic packings e,
the screws 6³ and c, and the calks f, substantially as described.
