PROVISIONAL SPECIFICATION.
Improvements in and relating to the Roughing of Shoes for Horses
and other Draught Animals.
We, ARTHUR PRIVETT, of 41 High Street, Erith, in the County of Kent, Smith and
Farrier, and STEPHEN JOHN TAYLOR, of Lower Road, Belvedere, also in the County of
Kent, Smith, do hereby declare the nature of this invention to be as follows:
The object of this invention is to provide means for roughing horse and similar shoes
without the necessity of taking the shoes off the animals' feet.
According to this invention we provide three plates, two of which are similar to each
other and carry the calks or frost hits for roughing, while the third is a transverse bar
which serves to attach the other two to each other, and to the shoe. The transverse
bar is slightly arched or curved vortically and is intended to be placed across the
bottom of the hoof and to take under the inside edges of the shoe. In its centre is
rigidly affixed a stud screwed at its upper end for receiving a nut.
Each roughing piece consists of a curved flat plate provided with vertical frost studs
or calks and with pins fixed to the reverse side which said pins bear against the inside
edge of the shoo and serve to keep the plate in proper position. An eye is formed in
the plate which said eye is placed over the screwed stud on the transverse bar, and
secured by a nut screwed tightly over the end of the said screwed stud.
The eyes of the two roughing plates are serrated on their contiguous surfaces so
that the two plates cannot shift when the nut is screwed up.

COMPLETE SPECIFICATION.
Improvements in and relating to the Roughing of Shoes for Horses
and other Draught Animals.
We, ARTHUR PRIVETT, of 41 High Street, Erith, in the County of Kent, Smith and
Farrier, and STEPHEN JOHN TAYLOR, of 30 Maximfelt Road, Erith, aforesaid, Smith,
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:
The object of this invention is to provide means for roughing horse and similar shoes
without the necessity of taking the shoes off the animals feet.
According to this invention we provide three plates, two of which are similar to
each other and carry the calks or frost bits for roughing, while the third is a trans-
verse bar which serves to attach the other two to each other, and to the shoe.
The transverse bar may be slightly arched or curved vertically and is intended to be
placed across the bottom of the hoof and to take under the inside edges of the shoe.
In its centre is rigidly affixed a stud screwed at its upper end for receiving a nut.
Each roughing plate consists of a curved flat plate provided with vertical frost studs
or calks and with pins fixed to the reverse side which said pins bear against the inside
edge of the shoe and serve to keep the plate in proper position. An eye is formed in
the plate which said eye is placed over the screwed stud on the transverse bar, and
secured by a nut screwed tightly over the end of the said screwed stud.
The eyes of the two roughing platos are serrated on their contiguous surfaces
so that the two plates cannot shift when the nut is screwed up, or a wedge piece

page_text: tightened by a nut on a bolt affixed to the transverse bar at right angles thereto, is
preferably adopted.
And in order that our invention may be more fully understood and carried into
practice, we will now proceed to describe the same with reference to the accom-
panying drawings in which similar letters are used to indicate corresponding parts
throughout.
Figure 1 is a plan, Figure 2 an inverted plan, and Figure 3 an edge view of a
horse shoe with our invention applied thereto; Figures 4 to 9 shew details of our
invention and Figure 10 shews a modification thereof.
Figure 1 represents a plan of a shoe as it would be seen when looking at the bottom
of the horse's hoof to which it is affixed. A is the transverse bar, the ends of which
are fitted under the edges of the shoe B, as shewn in Figures 1 and 2. This can
be easily effected when the shoe is on the hoof, by first passing one end under the
edge of the shoe, and turning the bar A at an anglo to the position shewn, so that it
lies across a greater diameter of the shoe. The other edge is then slipped under the
shoe and the bar A turned or knocked into the central transverse position shewn in
Figures 1 and 2. In the centre of the bar A a vertical bolt or screwed stud C is
affixed, or the stud may be cast in one with the bar and afterwards screw-tapped.
A similar bolt or screwed stud D is attached to, or formed on, a lug E projecting
horizontally from the centre of the bar A. Figures 6 and 7 shew the transverse bars
and the two bolts or screwed studs. Figure 6 shews the bar in plan and Figure 7 is
an edge view taken in the direction of the arrow shewn in Figure 6.
Figures 4 and 5 shew plan and edge view of one of the plates F, carrying the
roughing studs, calks, or frost bits H, two of these plates Fare used, but they are
similar in construction. The roughing plate F is flat and provided with an aperture J
at each end to receive the calks or frost bits, and with a central eye K, half the thick-
ness of the plate F. Two pins G are also affixed to the reverse side of the plate F.
The eyes K of the plates F are placed on the vertical bolt or screwed stud C, and
the two eyes will together equal the thickness of the plates F so that these said
plates lie in the same plane, and they are held together by the tightening nut L.
The four pins G bear against the inside edges of the shoe as shewn in Figure 2
and serve to keep the plates F in their proper position. To still further secure
the plates F, the horizontal bolt or screwed stud D is used. A wedge pioce M
shewn in elevation and plan in Figure 8, is provided with a central aperture or
eye N which is sufficiently large to pass easily over the bolt D. The ends O of
this wedge piece are bevelled and V shaped as shewn, so as to embrace the bevelled
edges of the plates F. The tightening nut P is then screwed up, forcing the wedge
piece up between the plates F and thus pressing the pins G firmly against the inside
edges of the shoe. Lock nuts may be used on both the bolts C and D if desired.
The frost hits or calks H we prefer to use, are of the shape shewn in Figure 9, and
are placed in the apertures or eyes J from the under or reverse side of the plates F
and are driven tightly home by a blow from a hammer or the like. When the plates F
are in position on the shoe, the heads Q of the frost bits or calks H bear against the
wearing surface of the shoe. Figure 9 shews a part section of the shoe with one of
the frost bits in position.
In Figure 10 we have shewn a modification of our invention adapted to take
calks made from blocks of india-rubber. The roughing plates F are made with
longitudinal grooves, into which the rubber calks are slid end ways, or they are forced
in by pressure, or otherwise fitted.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
(1) For roughing shoes for draught animals without removing the shoes from the
hoofs, the transverse plate A to fit under the edges of the shoe, having a central
vertical bolt C on which the eyes K of the roughing plates F are passed and secured
by a nut or lock nut L, the said roughing plates F being provided with pins G on the

page_text: reverse side bearing against the inner edges of the shoe, substantially as and for the
purpose herein before set forth and illustrated.
(2) In combination with a transverse plate, such as A, having a vertical bolt
carrying roughing plates such as F provided with pins bearing against the inner edges
of the shoe, the horizontal bolt D and wedge piece M tightened against the inner
edges of the said roughing plates F by the nut or lock nut P all operating substan-
tially in the manner described and illustrated, and for the purpose stated.
