PROVISIONAL SPECIFICATION.
Improvements in and connected with Means for Roughing Horse
and similar Shoes.
1, MARCELINE BOUTOILLE of 40 Rue Pascal Paris in the French Republic, Spinster,
do hereby declare the nature of this invention to be as follows :―
This invention relates to means for roughing the shoes of horses, mules, asses, and
other animals similarly shod, and these improvements consist in the construction and
arrangement with the shoe of a separate roughing device which carries the frost cogs
and which may be connected with and removed from the shoe with great facility.
The roughing device or apparatus constructed according to these improvements
consists of an iron or steel T-piece of which the end of the vertical member engages
by a slot or groove with the inner edge of the toe of the shoe, and of which the ends
of the horizontal member are formed to overlie a part of the heel ends of the shoe.
A slightly flexible steel plate corresponding to the horizontal member of the T-piece
is connected with the horizontal member by a central pivot one end of which is
riveted to the steel plate. The other end of the pivot is provided with a rectangular
head or nut by means of which the pivot may be turned (and with it the steel plate
to which it is riveted), by means of a suitable spanner or key. The ends of the steel
plate enter between the heels of the shoe and hoof, consequently, when the steel plate
is turned parallel with the horizontal member of the T-piece the heel ends of the
shoe will be gripped between the ends of the steel plate and the ends of the horizontal
member of the T-piece and at the same time the end of the vertical member of the
T-piece will be firmly held by its slot engaging with the toe of the shoe.
When it
is desired to remove the apparatus from the shoe it is necessary only to turn the head
of the pivot, when the steel plate will be turned so as to clear the shoe and the
apparatus may be withdrawn.
The frost cogs are preferably screwed into the T-piece, and the inner ends of the
screws may have nicks formed in them so that in case the frost cogs should become
incapable of being used for their removal, the screws may be turned by a screw-
driver. A small nib or projection may be formed upon the steel plate so as to abut
against the T-piece and tend to keep the steel plate in position.
A suitable tool for putting on and removing the device consists of a spanner
having at one end a slot fitting the head of the pivot, and at the other end a slot
fitting the frost cogs; a screw-driver is also formed on the spanner.

COMPLETE SPECIFICATION.
Improvements in and connected with Means for Roughing Horse
and similar Shoes.
1, MARCELINE BOUTOILLE of 9 Rue de Florence Paris in the French Republic,
Spinster, 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 the means for roughing the shoes of horses, mules, asses,
and other animals similarly shod, and these improvements consist in the construction
and in the combination and arrangement with the shoe, of a separate roughing device
which carries the frost cogs and which may be connected with and removed from the
shoe with great facility

page_text: I will describe my invention with reference to the accompanying drawings in
which
Figure 1 represents a horse shoe fitted with my improved roughing iron as viewed
from the underside;
Figure 2 is a plan of the roughing iron alone;
Figure 3 a plan of a modification of Figure 2;
Figure 4 the reverse of Figure 1 ;
Figure 5 an end view of Fig. 2;
Figure 6 is a simplification of the roughing iron shewn in Figures 2 and 3; and
Figure 7 is an end view of Figure 6.
The roughing iron or device constructed according to these improvements consists
of an iron or steel T-piece of which the vertical member A engages by means of a
slot or groove B with the inner edge of the toe of the shoe, and of which the ends of
the horizontal member Care formed to overlie a part of the underside of the heel
ends of the shoe. A slightly flexible steel plate Ď corresponding to the horizontal
member of the T-piece is connected with C by means of a central pivot E. This
pivot is welded or otherwise secured to the plate D, is furnished with a rectangular
or non-circular head F, and is secured at its outer end to C in such a manner as to
be capable of turning therein as indicated in the drawings. The connection of the
pivot E to the plate C may be conveniently effected by forming a shallow rivet head G
upon the slightly projecting part of the pivot below the plate C and it (together with
the spring plate D) may be turned as required by means of a suitable key fitting
upon F. The ends of the spring plate D are constructed to enter between the hoof
and the heel ends of the shoe; consequently, when this plate is turned parallel with
the member C, the heel ends of the shoe will be firmly gripped between the ends of
the steel plate D and the ends of the part C. In the form of the apparatus shewn in
Figures 1 to 4, the slot B will be caused to engage with the inner edge of the shoe
in inserting the roughing iron to its place as shewn in Figures 1 to 4 and this, in
combination with the grip of the plates D and C will hold the roughing iron securely
in position during wear. When it is desired to remove the roughing iron from the
shoe, it is necessary only to turn the head F of the pivot E by means of a suitable
key, when, since the angular motion of the pivot is shared by the plate D, the
apparatus may be readily removed from the shoe.
In the modification represented in Figure 3, the forward end of A is spatular or
broadened so as to permit the use of four or five frost cogs if required.
In the modification represented in Figures 6 and 7 the vertical member A of the
roughing iron is omitted altogether. This modification may be adopted with animals
of light draught.
A small nib or projection H may be formed upon D and will tend to keep the
plate in position by butting against the plate C; this object is further secured by
means of the small hole I pierced in D in such a position that the screwed part of
one of the frost cogs may enter therein when the cog is inserted into the iron on
the shoe.
The frost cogs K K are preferably screwed into the roughing iron and for this
purpose they are formed as shewn with screwed stems and square bodies upon which
a key may be fitted to screw them into position or for removing them from the
roughing iron. To provide for the event of the body of the frost cog being broken
off, or being otherwise rendered incapable of being removed by means of the screw
key or spanner, I form a nick L in the end of the screw as shewn in Figure 8 which
represents one of the frost cogs in elevation and a plan of the end of the screwed
shank of the cog respectively. The cogs may be of any convenient size as may be
determined in each particular case, and they may be three in number as in Figures 1
and 4; two only as in Figures 6 and 7; four, as in Figure 3; or five, by adding
one to about the centre of the broadened part of A Figure 3.
A suitable tool for putting on and removing the frost cogs and the roughing
iron consists of a spanner having at one end a slot or opening to fit the head F of the

page_text: pivot E and a similar opening to fit the frost cogs ; at the other end of the tool a
screw-driver is formed.
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) A roughing device or apparatus to be applied to the shoes of horses asses and
mules and to other similar shoes; constructed and arranged substantially as herein-
before described.
(2) The combination with a horse or similar shoe of a roughing plate A, a spring
plate D pivoted thereto, and screwed frost cogs inserted therein, constructed and
arranged substantially as and for the purpose hereinbefore described and as illustrated
by the accompanying drawings.
