One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the said
Polydore de Keyser, Her special licence that I, the said Polydoro de Keyser,
my executors, administrators, and assigns, or such others as I, the said Polydore
de Keyser, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during. tho
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN APPARATUS FOR PREVENTING
HORSES SLIPPING," (a communication,) upon the condition (amongst others) that
I, the said Polydore de Keyser, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Polydore de Keyser, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
The Invention consists of an apparatus to be fixed to horses' shoes for the
purpose of giving to horses a firm foothold when the surface of the ground,
roads, or streets is in a slippery state, from ice, snow, frost, or other causes.
The apparatus consists of a piece of iron or other hard metal about a
quarter of an inch in thickness, turned up at each end, so as to form two arms

page_text: projecting upwards, one arm about half an inch, the other arm a little more,
the said arms forming a groove of sufficient width to fit a portion of the rim
or flukes or ends of a horse's shoe; an opening is formed in the piece of iron
or other hard metal in the centre of the groove thus formed, in order that
a piece of iron, steel, or other hard metal may be affixed, as herein-after
described. One of the arms is furnished with an ordinary nut screw, the other
arm is made a little higher than the afore-mentioned arm, and thinner at the
upper than at the lower part, and is inclined inwards towards the groove at the
upper part. The arm furnished with the nut screw should be placed inside the
shoe. On the under side of the piece of iron or other hard metal, being the base
of the apparatus, I affix a piece of iron, steel, or other hard metal, terminating
in a point or points at its lower extremity. The said apparatus is applied to
each or to either shoe by placing one or more on the rim or flukes or ends of
the shoe, and adjusting the nut screw so as to firmly attach the apparatus to the
horses' shoe the point or points at the base of the apparatus are thus brought
to the tread of a horse. The apparatus can be removed by withdrawing the
said nut screw.
Having now fully described the nature of the Invention, I would have it
understood that I do not confine myself to the precise details herein described,
so long as the peculiar character of the Invention be retained; but what I
claim is the apparatus herein described for giving to horses a firm foothold in
slippery weather.
In witness whereof, I, the said Polydore de Keyser, have hereunto set
my hand and seal, this Twenty-sixth day of October, in the year of
our Lord One thousand eight hundred and fifty-seven.
POLYDORE DE KEYSER. (L.S.)
