IMPROVEMENTS IN HORSE HOES
Year: 1859

page_text: LETTERS PATENT to Isaac Spight, of Glandford Briggs, in the County
of Lincoln, Ironfounder and Agricultural Machine Maker, for the Inven-
tion of "IMPROVEMENTS IN HORSE HOES."
Sealed the 22nd September 1859, and dated the 29th March 1859.
PROVISIONAL SPECIFICATION left by the said Isaac Spight at tlie
Office of the Commissioners of Patents, with his Petition, on the
29th March 1859.
I, ISAAC SPIGHT, of Glandford Briggs, in the County of Lincoln, Iron-
founder and Agricultural Machine Maker, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN HORSE HOES," to be as follows, that
is to say:-
This Invention has for its object improvements in horse hoes. For these
purposes the hoes are attached to levers connected with a revolving shaft near
the front of the machine. This revolving shaft works on bearings in a slide
frame, and is raised or lowered by turning a handle attached to a spindle
working a rack or worm thread, by means of which all the hoes work on the
same level. One end of each of the levers to which the hoes are attached
being fixed to this revolving shaft by sockets or otherwise, instead of hanging
loosely, as heretofore, the hoes will all cut level, and not be liable to dip on
one side. The depth to which the hoes penetrate the ground is regulated by
the height of the rovolving shaft in the slide frame. At the top of each of the

page_text: hoes is a socket, which slides upon the lever connected with the revolving
shaft, and which may be fixed in any position required for different kinds of
corn or roots by set screws, clasps, or otherwise.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Isaac Spight in the Great Seal Patent Office on the
29th September 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISAAC
SPIGHT, of Glandford Briggs, in the County of Lincoln, Ironfounder and
Agricultural Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of March, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Isaac Spight, Her special licence that I, the said Isaac Spight,
my executors, administrators, and assigns, or such others as I, the said
Isaac Spight, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN HORSE HOES," upon the condition (amongst others) that I, the said
Isaac Spight, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
uscertain 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 Isaac Spight, do hereby declare the
nature of my 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:-
My Invention has for its object improvements in horse hoes. For these
purposes the hoes are attached to levers connected with a revolving shaft near
the front of the machine. This revolving shaft works on bearings in a slide
frame, and is moved by turning a handle attached to a shaft working a rack
or worm thread, by means of which all the hoes work on the same level. One

page_text: The.depth to which the hoes penetrate the ground is regulated by the height
of the revolving shaft in the slide frame. At the top of each of the hoe shanks
is a socket which slides upon the lever connected with the revolving shaft, and
which may be fixed in any position required for different kinds of corn or roots
by set screws, clasps, or otherwise.
Having thus particularly described the nature of my said Invention, I now
proceed to particularly describe and ascertain in what manner the same is to
be performed, reference being had to the Drawings hereunto annexed, and the
letters and figures marked thereon, that is to say :-
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan and Fig. 2 a side view of the implement; Fig. 3, a plan of
the top frame, hangers, brackets, and steering shaft; Fig. 4, a view of one
lever, hoe shank, and hoe; and Fig. 5, a view of the back of the implement,
and the letters refer to the same parts in each of the Figures.
A is the revolving shaft to which the hoe levers J, J, are connected, and
which can be moved to any required distance; G is a wheel on the shaft A,
which may be made to revolve by the worm gear on the shaft H. When the
shaft H is turned by the handle I, the worm gear causes the wheel G to
revolve, and this carries with it the shaft A, and by this means more or less hold
is given to the hoes to suit the ground. The shaft H is fixed to the hangers B, B,
by suitable bearings, and is fitted with an universal joint near the hangers
B, B, and at its other end it runs in a bearing fixed on two centres, so that
when the hangers B, B, are moved either to the right hand or to the left by
the shaft D, the shaft H is kept at ease. B, B, are the hangers to which the
revolving shaft A is laid parallel on bearings, and which runs on rollers either
to the right hand or to the left when steered by the shaft D. C, C, are the
brackets on the top frame, on which the hangers B, B, work.
B, B, are connected together at the top, by rods F, F, and at the bottom
by the revolving shaft A, and by this means the hoes, the hangers B, B, and
the shaft A travel at the same speed, and the hoes are also kept on the same
level at the bottom. J, J, are the levers fixed on the revolving shaft A.
K, K, are the boxes to which the hoe shanks L are bolted, and they can be
fixed with clasps, set screws, or any other convenient means at the required
distance on the levers J, J. When several hoes are required to work in one.

are attached, which can be easily replaced when required.
In witness whereof, I, the said Isaac Spight, have hereunto set my hand
and seal, this Twenty-seventh day of September, in the year of our
Lord One thousand eight hundred and fifty-nine.
ISAAC SPIGHT. (L.S.)
