Improvements in Shoes for Horses.
We FRANCIS LAWRENSON, of No. 14 Dandy Row, Eccles Hill, Darwen in the
County of Lancaster, Hose Knitter and HENRY SHAW, of Higher House Farm
Darwen aforesaid, Carriers Manager, do hereby declare the nature of this invention
be as follows:-

This invention relates to improvements in appliances employed for "sharpening"
or roughing" the shoes of horses, mules and other draught animals to prevent
their slipping in frosty weather, or on slippery ground, and also to improved
construction of shoes used in connection with such sharpening of appliances.
According to this our said invention the shoes are formed with dovetail or dove-
tail and tapered grooves formed in them, preferably three in number, one at the toe
of the shoe, and one at each end of the heel. Into these grooves or recesses are
forced caulkings, toe pieces or other sharpening devices which fitting tightly and
it
accurately in the grooves or recesses are quite firm, and when in practical use,
is found that rust or corrosion makes the caulkings or sharpening device
unmovable.
The caulkings or sharpeners, may if thought desirable be further secured by
means of screws, wedges or other appliances.

COMPLETE SPECIFICATION.
Improvements in Shoes for Horses.
We FRANCIS LAWRENSON of No. 14 Dandy Row, Eccles Hill, Darwen, in the
County of Lancaster Hose Knitter, and HENRY SHAW of Higher House Farm,
Darwen aforesaid, Carriers Manager 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 :-
22
This invention relates to improvements in appliances employed for "sharpening,"
or "roughing "the shoes of horses, mules, and other draught animals, to prevent
their slipping in frosty weather, or on smooth or slippery ground, and also to
improved construction of shoes used in connection with such "sharpening
"roughing" appliances.

or
According to this our said invention the shoes are formed with dovetail, or dove-
tail, and tapered grooves, or recesses in them, preferably three in number, one at
the toe of the shoe, and one at each end of the heel. Into these grooves, or
recesses are forced caulkings, toe pieces, cr other sharpening devices which fitting
tightly and accurately in the grooves, or recesses are quite firm and when in
practical use it is found that rust, or corrosion makes the caulkings, cogans, or
other sharpening devices practically unmovable, but if thought desirable the
sharpening devices may be further secured by means of set screws, pins, or other
devices.
Such being the nature, and object of our said invention the following is a com-
plete description of same, reference being made to the accompanying drawings in
which:-
Fig. 1. is a plan view of the underside of a horse shoe shewing the dovetail

page_text: recess at the toe, and heels, for the reception of the cogans, caulkings, or cogs, one
of which is shewn in position in the heel.
Fig. 2. is a side elevation of a horse shoe shewing the dovetail recesses, and the
caulkings, or cogs in position therein.
Fig. 3. is a front view of a toe piece detached.
Figs. 4 and 5. are frost nails, cogs, or cogans shewn both sharp and blunt.
Figs. 6. and 7 are end views of toe pieces shewn both sharp, and blunt.
Fig. 8 is a view of the heel portion of a shoe shewing the dovetail recess formed
transversely to the length of the shoe.
According to this our said invention the shoes 1 are formed with dovetail or
taper grooves or recesses 2. 2. 2 in them, and preferably three in number one
being at the toe of the shoe, and one at the end of each heel. The groove, or
dovetail recess at the toe of the shoe is formed part way across it, i.e. at right
angles, or transversely to its length, and those in the heels are formed either
lengthwise as shewn by Fig. 1. or transversely and at right angles to the length of
the shoe (see Fig. 8.).
Into these grooves, or recesses 2. 2. are forced toe pieces, or caulkings, such as 3,
or frost nails, cogans, or other sharpening or roughing devices such as 4. the toc
piece 3 being made about as long as the width across the toe of the shoe, and the
frost nails, or cogans 4 are made in the ordinary way, and of the usual shape.
Both the toe pieces, or caulkings 3, and the frost nails, cogans, or cogs 4 have
dovetail projections 5 cast to or otherwise formed on them, corresponding to the
dovetail recesses 2. 2. These locking pieces 5. 5. are knocked or forced into
the recesses 2. 2. which may either be formed transversely in the shoes as above
described, in which case there is little liability or tendancy for the cogans, frost
nails, or cogs, to slip or be drawn out when in actual use, or if longitudinal recesses
are employed it is advisable that a small stop screw, or pin 6 be employed, and
screwed into the shoe, and the head of such pin, or screw will prevent the frost
nail, cogan, or cog 4 from moving, or being withdrawn until the former is
unscrewed and removed.
It is found also that when in actual use, that rust, and corrosion of the metal
will fix the toe pieces, cogans, frost nails, or cogs in position, but not so firmly that
they cannot be removed, when desired, by striking with a hammer, and it will be
understood that the sharpening, or roughing devices, can be removed, and renewed
many times without removing the shoe from the hoof of the animal, and much
time spent in "shoeing is thereby saved, and the hoof of the animal is also
preserved.
"
Having now particularly described and ascertained the nature, and object of our
said invention, and in what manner the same is to be performed we declare that
what we claim is :-
.1. A cogan, frost nail, toe piece, or cog having a locking device such as 5
sliding into, and being held by a transverse or cross groove such as 2 formed in the
shoe as illustrated, and herein fully described.
2. A cogan, frost nail, toe piece, or cog having a locking device such as 5
sliding into a groove or recess formed in the shoe, and secured by stop screw, or
pin such as illustrated, and as hercin fully described.
