page_text: I JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been
communicated to me from abroad by Adolphe Cyrille Constant Robert of Paris
in the Republic of France, Farrier, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:-
This Invention relating to frog pads for horses or other animals consists in
making the pads in an improved manner and in providing them with a
strengthening or stiffening plate as hereinafter described.
And in order that the said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 of the accompanying drawings represents a longitudinal section of a
rubber frog pad made according to this Invention and applied to a fore shoe.
Figure 2 represents a transverse section of the same the section being taken along
the line ✗-Y figure 3 and Figure 3 is a plan of the underside of the pad.
Figure 4 is a plan of a pad for the hinder shoe."
A represents the improved elastic frog pad which is provided with a ring A¹
extending all round the inner edge of the shoe and formed with a web or flange A
which engages under the shoe indicated at B figures 1 and 2. The pad A and
parts A¹ A' are of rubber moulded in one piece and the pad A is provided with a
number of studs or projections h. An important feature of the invention consists
in the means employed to strengthen or stiffen the heel part of the pad and render
it less liable to be cut at the hinder edges. With this object a strengthening
plate m n is imbedded in the substance of the pad being introduced in the process
of moulding or forming the latter. This plate greatly strengthens the middle part
and edges of the pad and prevents cutting of the edges by the heels of the shoe.
This strengthening plate is bent or curved and is shewn by full lines in figures 1
and 2 and by dotted lines in figures 3 and 4. The said plate is preferably of metal

page_text: but a piece of stiff leather or other suitable strengthening material may be used
instead.
The improved formation of the pad as hereinbefore described enables it to be
fitted to the foot of the animal without the necessity for paring the sole and the
frog is effectually protected by the rubber cushion A which affords a firm point of
support preventing slipping and falling. The heel is free to expand, straining of
the tendens and fetlock joint is avoided and the elasticity or flexibility of the
parts is completely preserved. Another important advantage of the pad made
according to this Invention is that it leaves the sole uncovered and enables it to be
attended to when required without removing the shoe and it further enables all
other frog protectors or similar appliances ordinarily employed to be dispensed
with and can be used with equal facility in English French or other systems of
shoeing. It is evident that the invention is not limited to the precise shape or
outline of the improved frog pad as illustrated in the drawing which may be
modified according to requirements without departing from the principles of
construction herein before set forth.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what
I claim is
A frog pad made substantially as hereinbefore set forth and illustrated whether
there be used therewith or not a stiffening or strengthening plate also substantially
as set forth and illustrated.
