through an eye formed in a projecting part of the shoe, the hook and lock piece,

This Invention relates to improved interchangable appliances for "roughing"
or sharpening the shoes of horses during frosts, and appliances for ordinary wear
without removing the shoes from the feet.
Heretofore the "stubs " made in the form of a wedge and screwed to the shoes
have been of such form as to be exceedingly liable to wedging between the "sets"
or pavement and being wrenched off and broken.
Appliances for purposes aforesaid I construct as follows:-In connection with
the front "cogan "I employ a plate branching at right angles therefrom; one end
of the plate is turned up, forming a hook, which embraces the inner edge of the
shoc, the other end of the plate terminates in a tongue or lock piece, which passes
through an eye formed in a projecting part of the shoe, the hook and lock piece,
aided by an ordinary set screw, secure the whole immovably. Another method is
that both ends of the plate extending from the cogan be of hook form, and clips
the inner and the outer edges of the toe of the shoe. The back cogans are made
with a pin and a projecting plate; the pin enters a hole in the shoe, and the plate
rests upon the shoc, to which (aided by the cogan pin) it is effectually secured by
means of a set screw.
For the heavy shoes of draught horses I weld or forge the toe or front cogan
to a plate which rests on a part of the shoe to which by set screws it is securely
attached. For lighter shoes of this class the plate has but one wing or part
projecting past the cogan, through which a set screw is passed; this arrangement
admits of the reversing of the cogan, there being holes for receipt of the set screw
at either side of the cogan. I also construct cogans having double cutting edges
in the form of the letter X.
In all cases I make the cogans or the ordinary screw "stubs" somewhat rounder
or cliptical, so as to avoid the wedge form, and I secure a broad shoulder on every
side of the holding pin or screw, so as to largely increase the bearing surface of the
shoulder of the "stubs" upon the shoe, the want of which has been the main cause
of breakage.
Such being the nature and object of this my said Invention, I will now proceed
to describe the same in detail, and in order that the Invention may be clearly
understood, I have hereunto annexed a Sheet of Drawings illustrative thereof.
DESCRIPTION OF FIGURES 1, 2, 3, & 4.
In connection with the front cogan A, I employ a plate B, branching at right
angles therefrom; one end of the plate B is turned up, forming a hook C, which
embraces the inner edge of the shoe D, the other end of the plate B terminates in
a tongue or lock piece E, this tongue is passed through the eye F, formed in a
projecting part G of the shoe D, the hook C and lock piece E, aided by the set
screw H, secure the whole immovably.
Figures 5, 6, and 7, shew another form or construction; in this, both ends of the
plate B, extending from the cogan A, are of hook shape; C, C, the hooks, clip the
inner and the outer edges of the toe or front part of the shoe D; at Figure 8 is shewn
the form of cogan A and plate B adapted for the heavy shoes of draught horses.
The cogan A is welded to the plate B. which rests upon and is secured to the

page_text: shoe D, by means of the pin or stud E and the set screws H, H. For lighter
shoes of this construction, see Fig. 9, where the cogan plate B has but one wing
or projecting part B₁, through which a set screw H is passed; this arrangement
admits of the reversing of the cogan (when partly worn), there being an additional
hole J formed through the shoe D for the receipt of the set screw H when the
cogan is reversed.
At Figs. 12, 13, I have shewn the front and back cogans
connected or formed on one plate R, and secured by means of set screws as described
in reference to the other Figures. The back cogans K are provided with a pin L,
passing into the shoe D, and have also a plate M, through which a set screw P is
passed, and enters the shoe, the set screw P and the pin L holding the cogan
securely, and preventing the twisting to which ordinary screw cogans are so
liable.
Screw cogans I make square or rectangular, and having X cutting edges, as
shewn at Figs. 10, 11.
20
It will be understood that the cogans are to be made with cutting edges or
'sharpened," or they may be made as shewn at Figs. 1, 2, 3, for ordinary work;
but in all cases the cogans are interchangable to the same shoe without removing
the shoe from the foot.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be performed or carried into
practical offect, I would have it understood that I claim the use and employment
of the improved cogans herein fully described and illustrated by Drawings.
In witness whereof, I, the said Miles Smith, have hereunto set my hand and
seal, this Twenty-fourth day of August, in the year of our Lord One thousand
eight hundred and seventy-six.
MILES SMITH.
