IMPROVEMENTS IN HORSE HOES
Year: 1862

page_text: LETTERS PATENT to Isaac Spight, of Glandford Briggs, in the County of
Lincoln, Ironfounder and Agricultural Machine Maker, for the Invention
of "IMPROVEMENTS IN HORSE HOES."
Sealed the 5th June 1863, and dated the 11th December 1862.
PROVISIONAL SPECIFICATION left by the said Isaac Spight at the
Office of the Commissioners of Patents, with his Petition, on the
11th December 1862.
I, ISSAC SPIGHT, of Glandford Briggs, in the County of Lincoln, Ironfounder
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:-
My Invention relates to improvements upon a Patent granted to me on
the 22nd day of December 1859, and being No. 786, for improvements in
horse hoes, and relates particularly to a method of regulating the depth at
which the hoes work when used on uneven ground such as hill sides or on
ridge land.
In my former Patent the hoes were attached to levers connected with a
revolving shaft working in a slide frame having bearings at each end, and
which shaft could be raised or lowered as required for different kinds of
corn or roots. My present improvement consists in suspending the shaft
or bar to which the hoes are attached upon a bearing at its centre, instead
of at each end, so that when one end is raised by turning a handle or other-
wise, as described in my former Specification, the other end is lowered in a
corresponding degree, and thus when working over ridged or curved surfaces
or along what are called "lands," the depth or bite of the hoes may be regu-
lated by the attendant with the greatest nicety.

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
day of
in the year of our
Lord One thousand eight hundred and sixty- , in the twenty-sixth 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 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 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
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 mouths 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 relates to improvements upon a Patent granted to me on
the Twenty-ninth day of March One thousand eight hundred and fifty-nine,
and sealed on the Twenty-second day of November One thousand eight
hundred and fifty-nine, and being No. 786, for improvements in horse hoes,
and relates particularly to a method of regulating the depth at which
the hoes work when used on uneven ground such as hill sides or on ridge
land.
In my former Patent the hoes were attached to levers connected with
a revolving shaft, working in a slide frame having bearings at each end,
and which shaft could be raised or lowered as required for different kind

page_text: of corn or roots. My present improvement consists in suspending the shaft
or bar to which the hoes are attached upon a bearing at its centre, instead of
at each end, so that when one end is raised by turning a handle or other-
wise, as described in my former Specification the other end is lowered in
a corresponding degree, and thus when working over ridged or curved surfaces
or along what are called "lands," the depth or bite of the hoes may be
regulated by the attendant with the greatest nicety.
Having thus described the nature of my said Invention, I now proceed to
particularly describe and ascertain in what manner the same is to be per-
formed, reference being had to the Drawings hereunto anuexed in which the
letters refer to corresponding parts in each Figure, that is to say,―
Fig. 1 is a side view of the implement; Fig. 2 a plan of the top frame,
hangers, brackets, and steering shaft; Fig. 3, the back part of thè hoe frame;
Fig. 4, the iron balance frame shewn on a level, and Fig. 5 the position of the
iron frame when working on a bill side or on uneven ground.
In Fig. 1 the horizontal shaft P moves a wheel Q which works into the.
rack R. This rack is attached to the balance frame M, which works between
the guide plates N, and which is raised or lowered by the steerer turning
the wheel O. C, C, are brackets in which the hangers B move, and which
also carry the revolving shaft A, to which the hoe levers J, J, are attached.
It will be seen that the hoes can be made to work on a level, or one end can
be raised higher than the other when desired by the steerer if he is working
on uneven or ridged land.
Having thus described the manner of carrying my Invention in effect, I
would remark that I do not confine myself strictly to the details herein-before
described, but what I particularly claim as my Invention is the arrangement
by which the revolving shaft which carries the hoes may be made to work
either horizontally or in an inclined position at the will of the steerer when
working on ridge or uneven lands.
In witness whereof, I, the said Isaac Spight, have hereunto set my
hand and seal, this Ninth day of June, in the year of our Lord
One thousand eight hundred and sixty-three."
ISAAC SPIGHT. (L.S.)
