A New or Improved Pad for Horse Shoes.
We, LOUIS GRÜNFELDER, of Belfort, in the Republic of France, Merchant,
and EMILE HAUVILLER, of Mulhouse, in the Province of Alsace, Empire of
Germany, Merchant, 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:-
Our invention relates to a new or improved pad for horse shoes by which certain
advantages are obtained.
In the annexed sheet of drawings, we illustrate certain forms constituting or
embodying our invention or parts thereof.
In the said sheet of drawings,
Figure 1 is a side elevation,
Figure 2 is a view seen from below, and
Figure 3 a transverse section of one form of our invention.
Figures 4, 5 and 6 are respectively a plan view, a view from below and a sectional
view of a horse shoe fitted with a form of our invention.
Figures 7, 8 and 9 illustrate in transverse section different modifications of our
invention.
Figure 10 shows a modified method of applying our invention to a horse shoe.
Figure 11 is a key or tool adapted for use in attaching our invention to a horse
shoc.
Our invention consists essentially of a strip of vulcanized rubber A traversed
throughout its length by an elastic metallic core B whose extremities and g
extend beyond the rubber strip for a distance of an inch and a quarter or
thereabouts.
Referring to the form of our invention shown in Figures 1 to 6 it will be seen
that the upper surface d is inclined or bevelled and that there is a projecting part o
which may be gripped by the horse shoe as indicated by Figures 4 and 6.
As
will be seen by reference to Figure 1, a part of the rubber strip at the toe part is
made narrower as shown at e.
The core B consists preferably of a steel strip or blade one of the projecting ends
of which g is kept bent as shown in Figure 2 the other extremity f not being bent
until the pad is applied to the horse shoe. The said extremities and are
preferably bevelled off as will be seen in Figures 1, 2 and 6 for a distance of about
four fifths of an inch from the end.
The pad as described is curved to the shape of the horse shoe to which it is to
be applied (see Figure 4 for example) and when so applied the elasticity of the
core B keeps the said pad tightly pressed against the inner wall of the shoe. After
the pad has been thus placed in position the extremities of and of the flexible
core B are preferably inserted into the slots h, h cut on the upper surface of the
shoe as shown. The depths of the slots hh are proportional to the depth of the
iron of the shoe but ought not to exceed one third of the said depth.
Of the four shoes which go to make up a set one should bear a slot i (see
Figures 4, 5 and 6) cut at the heel thereof the function of which is to bend the
extremities of those cores which have not been bent in advance.
To fix the pads in position a special tool or turnscrew shown in Figure 11 may
be employed. It consists of a blade resembling that of an ordinary screw-driver
fixed in a handle. In the centre of the said blade is a slot o corresponding in its
dimensions with a section of the core B. By passing the extremity of the core B
through the said slot o the bending of the said extremity can be easily completed.

page_text: The said tool also serves to aid in the insertion of the said extremity in the slots h
of the shoe and for this purpose it is furnished with a notch n. The said tool
serves also to aid in withdrawing the pad from the shoe. For this purpose it may
be placed under one of the bent extremities and between it and the inner edge of
the shoe when by giving the tool say a quarter of a turn the said extremity is
disengaged from the slot h.
Figure 10 illustrates the application of our invention in a modified manner. In
this case the extremities and g of the flexible metallic core B engage in slots h', '
cut in the upper surface of the shoe close to and one on each side of the toe. The
pad thus placed serves to protect the frog of the hoof.
The dimensions of the pad constituting our invention may be varied to accord
with the shoes to which they are applied..
We have now described and illustrated a type of our invention which we have
found to give the best results of those forms which we have as yet tried in practice:
but we desire it to be understood that we do not limit ourselves to the means of
attachment of the pad to the shoe hereinbefore specified. For example, instead of
bending round the extremities of the core as hereinbefore set forth, we might
furnish the said extremities with studs adapted to fit into orifices in the body of
the shoe or, vice versa, we might perforate the said extremities with orifices or slots
adapted to engage studs fixed upon the walls of the shoes themselves. Or, we
might provide the inner wall of the shoe with recesses, projections, claws, or other
gripping or retaining devices adapted to clasp or engage the said pad or attaching
devices forming a part thereof or attached thereto.
Nor do we limit ourselves to the relative positions of rubber strip and core
illustrated. We may, for example, instead of having the strip B embedded within
the mass of the rubber fit it in a lateral groove of the said strip of rubber and in
some cases the said groove instead of existing beforehand may be simply formed by
the pressure of the said piece B upon the wall of the said rubber.
The advantages presented by our. invention will be obvious to all persons
conversant with the art to which our invention applies.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is.
1. The new or improved pad for horse shoes substantially as specified.
2. The new or improved form of pad for horse shoes substantially as set forth
with reference to Figures 1 to 10.
3. The combination of a massive rubber strip and a flexible metallic strip
substantially as and for the purpose set forth.
4. The means of attachment of the pad to the horse shoe substantially as set
· forth.
