Company, Patent Agency, of Frankfort-on-the-Main, in the Empire
of Germany, for the Invention of "IMPROVEMENTS IN HORSE-SHOES."--
A communication from the Continental Caoutchouc and Gutta

PROVISIONAL SPECIFICATION left by the said Frank Wirth at the
Office of the Commissioners of Patents, with his Petition, on the
12th May 1875.
I, FRANK WIRTH, of the Firm of Wirth and Company, Patent
Agency, of Frankfort-on-the-Main, in the Empire of Germany, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
HORSE-SHOES," a communication from the Continental Caoutchouc and
Gutta Percha Compagnie, of Hannover, in the Empire of Germany, to
be as follows:—

page_text: prevent horses slipping when going on slippery roads, and to provide a
protection for the under side of the hoof. It consists of a piece of
caoutchouc of the form of the inner edge of the shoe, and a transverse
slit or slot is made through said caoutchouc piece, through which slot is
passed a flat piece of steel extending a short distance beyond the
caoutchouc piece on both sides thereof, which piece of steel acts as a
spring for securing the pad in the recess formed by the shoe and hoof.
The ends of the shoe are made so as to approach or lie nearer each other
than usual, and a pair of callipers are employed for placing the pad in
position.
1
When the horse is shoed the caoutchouc pad with its spring is placed
against the recess on the under side of the hoof, and the callipers are
applied so as to force the caoutchouc and the spring to "give" or bend,
whereupon the ends of the spring will enter below the inner sides of the
horse-shoe and hold the caoutchouc pad in position, the outer edges of 1
the said pad being embraced and held by the inner sides of the horse.
shoe.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frank Wirth in the Great Seal Patent Office on
the 9th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANK
WIRTH, of the Firm of Wirth and Company, Patent Agency, of
Frankfort-on-the-Main, in the Empire of Germany, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of May, in the year 2
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Frank Wirth, Her special
licence that I, the said Frank Wirth, my executors, administrators,
and assigns, or such others as I, the said Frank Wirth, my executors, a
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN 3

page_text: Figure 3 is a cross section on the line y, y, in Figure 2, showing the
slit by which the spring F is retained, the said slit is lined with any
textile fabric k.
Figure 4 is a plan view of the spring F when removed from the
buffer.
Figure 5 is a cross section through the line x, x, of Figure 2, showing
the position of the spring F in the buffer and the lining of the slit
retaining the said spring; the Figuro also shows the manner in which
the tongues, shown in Figure 8, are adapted if the buffer is to be placed
on the horse-shoe.
Figure 6 is a plan section through the buffer, showing a modification
of the spring which has to hold the buffer in its place when placed to
the hoof. The iron or steel blades f, f³, and f³, are fixed on the buffer,
when the caoutchouc mass is cast so that the mass as it cools retains the
said blades in a very firm manner.
The said blades like. the spring F 1
project beyond the lateral edges of the buffer, and their projecting parts
are inserted in the groove in the inner edges of the horse-shoe.
Figure 7 shows a pair of tongues with which the buffer is placed
between the space left by the lower surface of the horse's hoof and the
inner edges of the horse-shoe. The tongues are provided on their front 2
part with three points, namely, one point below n', and two points i on
the upper portion. The upper jaw of the tongues is for this purpose
bent in two branches at Z. The tongues represented in Figure 7 is
open and ready to grasp the buffer. If closed the tongues give to the
buffer a somewhat bent position, so that the projections of the spring F 2
or of the blades ƒ,ƒ, ƒ³ can go under the edges of the shoe and insert
themselves in the groove of the horse-shoe when the tongues are
opened.
Figure 8 shows another pair of tongues by which the buffer also can
be inserted in the horse-shoe. The position of these tongues when 3
placed on the buffer is shown in Figure 5.
With regard to Figure 5 it may be well understood that when the
tongues is entirely closed the buffer is bent, and the spring F has in its
longitudinal section a curved appearance ) so that it can be easily
insented with its und

page_text: Figure 6, is to be placed the bent buffer must be inserted at the toe with
the projecting blade ƒ first, and then with the two lateral blades.
Having thus fully described the said Invention as communicated to
me, and the manner of performing the same, I wish it understood that
I claim,-
First. The combination of a caoutchouc buffer having slit with lining k
of textile fabric, retaining spring F, and a horse-shoe, substantially as
herein described.
Second. With reference to Figure 6 the combination of a caoutchouc
buffer having iron or steel blades f,f', f, and a horse-shoe, substantially
as set forth and shown in the annexed Drawing.
In witness whereof, I, the said Frank Wirth, have hereunto set
my hand and seal, this Second day of November, in the
year of our Lord One thousand eight hundred and seventy-
five.
