Year: 1862

page_text: LETTERS PATENT to Joseph Bucknall, of Boston, in the County of
Lincoln, Mechanic, for the Invention of "IMPROVEMENTS IN THE CONSTRUC-
TION OF HORSE-HOES."
Sealed the 27th February 1863, and dated the 29th September 1862.
PROVISIONAL SPECIFICATION left by the said Joseph Bucknall at the
Office of the Commissioners of Patents, with his Petition, on the
29th September 1862.
I, JOSEPH BUCKNALL, of Boston, in the County of Lincoln, Mechanic,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF HORSE-HOES," to be as follows:-
My Invention of improvements in the construction of horse-hoes, relates to
a novel arrangement and construction of parts whereby the implement is
rendered more manageable, stronger, and less liable to derangement than the
ordinary implements of this class.
In my improved horse-hoe I use a cranked axle for the running wheels,
and on any convenient part of this cranked axle is secured a worm wheel
into which gears a snail or worm, so that by actuating this latter by means

page_text: of a handle or lever adapted to its shaft the cranked shaft may be turned
round in its bearings, and by that means be raised or lowered, thereby raising
or lowering the tines or other parts of the implement that may be attached to
or connected with the cranked axle. The tine bar is placed immediately
below the cranked axle of the running wheels, and the tine levers are mounted
on a round bar or shaft in front of the running wheels, the tine levers being
secured thereon by means of tightening screws so that their positions on the
round shaft may be altered and adjusted for the purpose of raising, lowering,
or regulating the inclination of the points of the tines, either in or out of the
ground.
In order to take the strain off the tine bar, draught bars are adapted to the
latter and connected at their opposite ends to the shafts. The front round
lever bar is suspended by links from a slotted bearing fixed to the framework
of the implement so that the front lever bar, and with it the levers and tines,
may be moved laterally in either direction by means of a hand lever which
turns on a central pin as a fulcrum, its outer end being connected to both
the ends of the round front bar of the implement by means of suitable links.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Bucknall in the Great Seal Patent Office on the
27th March 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BUCKNALL, of Kirton, in the County of Lincoln, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of September, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Bucknall, Her special license that I, the said Joseph Bucknall, my
executors, administrators, and assigns, or such others as I, the said Joseph
Bucknall, 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, exer-
cise, and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE CON-
STRUCTION OF HORSE-HOES," upon the condition (amongst others) that I, the said
Joseph Bucknall, by an instrument in writing under my hand and seal, should

page_text: 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 Joseph Bucknall, 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, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say):-
"
My Invention of "Improvements in the Construction of Horse Hoes
relates to a novel arrangement and construction of parts whereby the imple-
ment is rendered more manageable, stronger, and less liable to derangement
than the ordinary implements of this class.
In my improved horse-hoe I use a cranked axle for the running wheels,
and on any convenient part of this cranked axle is secured a worm wheel into
which gears a snail or worm so that by actuating this latter by means of a
handle or lever adapted to its shaft the cranked shaft may be turned round
in its bearings, and by that means be raised or lowered, thereby raising or
lowering the entire framework of the implement with the tines and other parts
attached to the frame. The tine bar is placed immediately below the cranked
axle of the running wheels, and the tine levers are mounted on a round
bar or shaft in front of the running wheels, the tine levers being secured thereon
by means of tightening screws so that their positions on the round shaft may
be altered and adjusted for the purpose of raising, lowering, or regulating the
inclination of the points of the tines, either in or out of the ground.
In order to take the strain off the tine bar draught bars are adapted
to the latter and connected at their opposite ends to the shafts. The front
round lever bar is suspended by links from two slotted bearings fixed to the
framework of the implement, so that the front lever bar and with it the
levers and tines may be moved laterally in either direction by means of a
hand lever which turns on a central pin as a fulcrum, its outer end being
connected to both the ends of the round front bar of the implement by means
of suitable links and screw couplings.
In the accompanying Drawing I have shown various views of my improved
horse-hoe. Fig. 1 is a side elevation, and Fig. 2 a plan view shewing the
general arrangement of the parts. a, a, are the running wheels which are
adapted to a cranked axletree b, b, which turns in bearings attached to the
framework c, c, of the horse hoe. On the cranked axle is keyed a worm

page_text: wheel d, into which gears a worm e on the horizontal shaft e', which is provided
with a winch handle ³, whereby it may be turned in either direction as may
be required. The stalks of the tines or hoes f are secured in the bars 9, 9,
which are jointed at their forward ends to a shaft or bar hat the front part of
the implement. This bar h is supported by suspension rods i, i, with pulleys
upon the slotted bearings, Fig. 3; drag irons or tension rods k are connected
at the ends to the shafts l. By this arrangement there will be a direct pull
on the tines without unduly straining any of the parts. It will be seen that
the chains are connected at their inner ends to a block at the end of a
hand lever m, whose fulcrum pin is fixed on the horizontal bar c, of the
framing, and to which bar the inner ends of the shafts 1, 1, are also affixed
as shewn in the Drawing. The upper ends of the arms i, i, are provided
with antifriction wheels which run on slotted arms n, n, as seen best in the
detached front view, Fig. 3, of this part of the apparatus, from which it
will be understood that the bar h may be moved laterally in either direction
by simply moving the hand lever m to the right or left on its centre of
motion. By this means the position of the tines or hocs may be adjusted
horizontally or laterally with great accuracy. In order to lift up the tines
temporarily from the ground a bar o, Figures 1 and 2, and seen best in the
detached view, Fig. 4, is suspended beneath the horizontal arms g of the tincs
in such a manner that the arms 9 will be supported by the bar o, which
is suspended from chains connected with the sectors p, p, which are mounted
on the horizontal shaft g. A hand lever is keyed on to the shaft q, and
this latter may therefore be turned on its axis by pulling down the hand
lever r, thereby causing the sectors to rotate, and by pulling up the bar o
to lift the arms or levers 9, 9, and thereby raise the tines from the ground.
In order to permanently raise the tines as will be required when transporting
the implement along a road it will only be necessary to pull down the lever "
to the frame c, where it will be held by a self-fastening balance catch; the tines
will then be lifted up and held permanently above the surface of the ground:
until the lever r is released.
Having now described my Invention and the manner of carrying the same
into effect, I claim as the Invention secured to me by Letters Patent as afore-
said constructing, combining, and arranging the several parts of horse-hoes in
the manner herein set forth.
I claim the combination of the tension chains and screw couplings j, with
the bar h, and the arms or levers g, and the tines or hoes f, and the mode of
suspending the arms or levers g.

page_text: I also claim the use in horse hoes of the cranked axletree 6, or any equivalent
contrivance for the purpose herein set forth.
In witness whereof, I, the said Joseph Bucknall, have hereunto set
my hand and seal, the Twenty-fifth day of March, in the year of our
Lord One thousand eight hundred and sixty-three.
Witness,
WILLIAM BARTON.
JOSEPH BUCKNALL. (L.S.)
