IMPROVEMENTS IN HORSE-HOES
Year: 1867

page_text: LETTERS PATENT to William Freeman Wilkinson, of the Firm of
Wilkinson and Son, of Eagle Foundry, Ely, in the County of Cambridge,
for the Invention of "IMPROVEMENTS IN HORSE-HOES."
Sealed the 22nd October 1867, and dated the 24th April 1867.
PROVISIONAL SPECIFICATION left by the said William Freeman Wilkinson
at the Office of the Commissioners of Patents, with his Petition,' on
the 24th April 1867.
I, WILLIAM FREEMAN WILKINSON, of the Firm of Wilkinson and Son, of
Eagle Foundry, Ely, in the County of Cambridge, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN HORSE-HOES," to be as
follows:-
My Invention has for its object both to regulate the depth to which horse-
hoes penetrate into the soil, and also to effect a uniform action of the hoe
independently of any unevenness in the surface of the land acted upon. For
these purposes I attach to the lever carrying the hoe an adjustable arm
having a wheel or roller attached to its extremity, such wheel or roller
being situated either in front of or behind the hoe, but by preference in front
of the same, and resting upon the surface of the land. By this arrangement

page_text: the wheel or roller in passing over uneven ground will cause the hoe to rise
and fall in a manner corresponding with the unevenness, and will therefore
prevent it from penetrating unequally into the land as is the case with hoes
of the present construction. The arm carrying the wheel, as also the hoe
itself, are made adjustable upon the lever so that the depth to which the hoe
penetrates may be regulated to any required extent by adjusting the relative
positions of the hoe and wheel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Freeman Wilkinson in the Great Seal Patent Office
on the 24th October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FREEMAN WILKINSON, of the Firm of Wilkinson and Son, of Eagle Foundry,
Ely, in the County of Cambridge, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Freeman Wilkinson, Her special licence that I, the said William
Freeman Wilkinson, my executors, administrators, and assigns, or such others
as I, the said William Freeman Wilkinson, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the 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 "IMPROVEMENTS IN HORSE-HOES," upon the condition
(amongst others) that I, the said William Freeman Wilkinson, my executors
or administrators, by an instrument 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 William Freeman Wilkinson, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, reference being bad to the accompanying

page_text: SUCCE
say:
My Invention has for its object both to regulate the depth to which
horse-hoes penetrate into the soil, and also to effect an uniform action of the
hoe independently of any unevenness in the surface of the land acted upon.
For these purposes I attach to the lever carrying the hoe an adjustable arm
having a wheel or roller attached to its extremity, such wheel or roller being
situated either in front of or behind the hoe, but by preference in front of the
same, and resting upon the surface of the land. By this arrangement the
wheel or roller in passing over uneven ground will cause the hoe to rise and
fall in a manner corresponding with the unevenness, and will therefore prevent
it from penetrating unequally into the land, as is the case with the hoes
of the present construction. The arm carrying the wheel, as also the hoe
itself, are made adjustable upon the lever, so that the depth to which the hoe
penetrates may be regulated to any required extent by adjusting the relative
positions of the hoe and wheel.
On the accompanying Drawing is shown the arrangement for carrying my
Invention into practice which I prefer.
Figure 1 shows a transverse section through the hoe frame, and Figure 2
shows a part plan of the same; similar letters of reference indicate similar parts
in both Figures. A is the lever hinged to the sliding bar B carried by the
frame C, to which lever is attached the bar D' carrying the hoe D by means
of a clamp E, whereby the hoe is rendered adjustable upon the lever. An
arm F is connected to the lever A in front of the hoe also by means of a
clamp E to render it adjustable, which arm carries the wheel or roller G ;
this roller in passing over the land causes the lever A and with it the hoe D
to rise and fall with the undulations thereof, and thus causes the hoe to act
equally on the land; also by adjusting the positions of the hoe D and roller G
relative to the lever A the depth to which the hoe penetrates into the land
may be regulated. A guide II is provided connected in an adjustable manner
to the sliding framing I to steady the hoe in its motion up and down. The
other parts of the hoe are well known and need therefore not be further
described. The adjustable arm F with wheel G may also be employed
without of necessity making the boe adjustable on the lever as described; or
the arm of the roller may be fixed to the lever and that of the hoe made
adjustable thereon, also other known contrivances may be employed instead
of the clamps E, E', for rendering the wheel and hoe adjustable
Having thus described the nature of my Invention, and in what manner the
same is to be performed, what I claim is,―

page_text: First, applying to the lever carrying the hoe a wheel or roller situated
either in front of or bebind the hoe substantially as and for the purposes
herein-before set forth.
Second, so connecting the arms of the hoe and wheel or roller to the lever
carrying the same that either the one or the other or both may be capable
of adjustment thereon, substantially as and for the purposes herein-before
set forth.
In witness whereof, I, the said William Freeman Wilkinson, have here-
unto set my hand and seal, this Twenty-first day of October, in the
year of our Lord One thousand eight hundred and sixty-seven.
WILLIAM FREEMAN WILKINSON. (L.S.)
