"IMPROVED ROUGHS FOR HORSE-SHOES."
My Invention relates to "roughs" adapted to fasten on to ordinary permanent
horse-shoes, and has for object the production of such " roughs" so adapted and
arranged that they may easily be applied to and removed from the permanent shoo
without the aid of a shoeing-smith.
The Invention consists in making a lower or false shoo in two halves, the joint
of which is by preference at the toe part thereof; this false shoe may be made in
wrought iron, steel, or malleable cast iron, and with any required number of
"roughs" forged or formed on the underside thereof. Each half of the false shoe
has also formed or forged on its inner circumference two or more clips or hooks
which take into the space between the inner bevelled edge of the permanent
horse-shoe and the hoof of the horse. Each half of the false shoe has also formed
or forged on its outer circumference clip pieces, which when the false shoe is
applied to the horse-shoe may be bent up over the outside of the permanent shoe
and the hoof so as to form a series of hooks or clips opposed to those in the inside,
whereby the false shoe is securely fixed to the permanent shoe.
The two parts of the false shoe may be so adapted as to fit into one another
after the manner of a hinge, or otherwise, and secured together after being put in
place on the horse-shoe by means of a pin or screw.
In some cases instead of forging or forming "roughs" upon the false shoe I
employ a layer of indiarubber placed between the false shoe and the permanent
shoe, and adapted to project at certain points either through openings in the said
false shoe or beyond narrow portions thereof, whereby a surface is produced well
adapted to prevent slipping on asphalte or other smooth roadways.

"IMPROVED ROUGHS FOR HORSE SHOES."
My Invention relates to "roughs" adapted to fasten to ordinary permanent
horse shoes, and has for object the production of such "roughs" so adapted and
arranged that they may easily be applied to and removed from the permanent shoe
without the aid of a shoeing smith.
In the Drawing hereto annexed, Figure 1 represents an underside view of a
"rough" manufactured in accordance with my Invention, and ready for application
to a permanent shoe of corresponding size already fixed to a horse's hoof; Figure 2
represents a side elevation of a horse's hoof with the permanent shoe and "rough'
attached thereto; Figuro 3 represents a transverse section on line 1-1 of
Figure 2. Similar letters refer to like parts in all the Figures of the Drawings.
"
The Invention consists in making a lower or false shoe A, A, (see the Drawings)
in two halves, the joint B of which is, by preference, at the front or toc part
thereof; this false shoe may be made in wrought iron, steel, or malleable cast
iron, and with any required number of "roughs" C, C, forged or formed on the
underside thereof. Each balf of the false shoe has also forged or formed on its
innor circumference two or more clips or hooks D, D, of any suitable shape, which
when bent up take into the space between the inner bevilled edge E of the
permanent horse shoe F and the hoof G of the horse (see Figure 3.) Each half
of the false shoe has also formed or forged on its outer circumference clip pieces
H, H, of any suitable form, which when the false shoe is applied to the permanent
horse shoe may be bent up over the outside of the said permanent shoo F and the
hoof G (see Figure 2), so as to form a series of books or clips opposed to those in
the inside, whereby the false shoe A is securely fixed to the perinanent shoe F.
The two parts of the false shoe may be so adapted as to fit into one another after
the manner of a hinge, as shown at B, and secured together after being put in
place on the horse shoe by means of a pin or screw I, or the two parts may be
joined together by any other suitable means. The object of making the false shoo
in two parts is to enable it to be applied to the permanent shoe after the inner
clips or hooks D, D, have been bent up, so as to fit into the space between the
inner bevilled edge of the permanent horse shoe and the hoof, as shewn at Figure 3,
which would not be possible if the false shoe were made in one piece. It is some-
times necessary to adjust the inner clips of the false shoe after the two halves are
placed on the permanent shoe by haminering, or otherwise bending them to place.
When the two halves of the false shoo are in place and jointed together by the pin
or screw I, the outer clips H, HI, aro bent up over the permanent shoc and the
hoof, as shewn, and the false shoe secured by the joint effect of the inner and outer
clips.
A padding of felt, india rubber, or other soft or elastic substance J may be
interposed between the false and permanent shoes if found desirable. Instead of
the false shoe being made in balves it may be made in two or more parts joined
together in any convenient way.
In some cases instead of forging or forming "roughs" upon the false shoo I
employ a layer of india rubber placed between the false shoc and the permanent
shoe, and adapted to project at certain points either through openings in the said
false shoe or beyond narrow portions thereof, whereby a surface is produced well
adapted to prevent slipping on asphalte or other smooth roadways.
Figure 4 is an under view, and Figure 5 a section on line 2-2 of Figure 4 of
part of a permanent and false shoe with the india rubber K interposed between

page_text: them and adapted to project through openings L in the false shoe; Figure 6 is an
under view, and Figure 7 n section on line 3-3 of Figure 6 of same, with the
india rubber K interposed between them but adapted to project beyond narrow
portions M of the false shoe.
It will be readily understood that the above described "roughs" or false shoes
may be easily applied when required without the aid of a shoeing smith to
the permanent shoes already secured to the animal's hoof.
Having now described the nature of the said Invention and the manner in which
the same is to or may be carried into effect, I would have it understood that
what I claim as my Invention is,—
First. The construction and use of "roughs" or false shoes made in halves or in
two or more parts, and attached to the permanent shoes by clips or hooks,
substantially as herein before described and illustrated in Figures 1, 2, and 3 of the
Drawings.
Second. The construction and use of false shoes attached to the permanent
shoes by clips or hooks, and having a layer of india rubber interposed between the
said false shoes and the permanent shoes, such india rubber being adapted to
project through openings in the said false shoes or beyond narrow portions thereof,
substantially as hereinbefore described and illustrated in Figures 4, 5, 6, and 7 of
the Drawings.
In witness whereof, I, the said George Thomas Mackley, have hereunto set my
hand and seal, this Twentieth day of August, in the year of our Lord
One thousand eight hundred and eighty.
