IMPROVEMENTS IN HORSE HOES
Year: 1857

page_text: LETTERS PATENT to John Naylor, of Winterton, near Brigg, Lincoln-
shire, for the Invention of "IMPROVEMENTS IN HORSE HOES."
Sealed the 24th April. 1857, and dated the 17th February 1857.
PROVISIONAL SPECIFICATION left by the said Robert Naylor at the
Office of the Commissioners of Patents, with his Petition, on the
17th February 1857.
J, JOHN NAYLOR, of Winterton, near Brigg, Lincolnshire, do hereby
declare the nature of my Invention for "IMPROVEMENTS IN HORSE HOES," to
be as follows:—
This Invention has for its object improvements in horse hoes. For theso
purposes each of the hoes is made capable of being moved to and from its
neighbour in order to admit of varying the distances apart of the different
hoes, and the whole series of hoes in a machine may, as hereafter explained,
also be moved laterally, according to the requirement for the time being.
Each hoe is attached by its stem to a lever arm, which moves independently
of the other lever arms. Each hoe has behind it a wheel to regulate tho
depth to which the hoe may penetrate into the land. Each of the lover arms
has a short tube or socket at its fore end, which slides on a short tube, which
moves on a fixed axis near the front of the machine, such tube having a
toothed rack formed thereon. Each of the sockets carries a pinion and one
end of an axis, and such axis at its other end turns in a bearing carried. by
the lever arm, to which the socket is attached.. The back ends of the lever

page_text: arms are suspended by chains to an axis above, in such manner that on
turning the axis by suitable gearing the whole of the lever arms will be
raised, and all the hoes may be lifted out of the land, or the lever arms may
be allowed to descend to and be retained at any desired position above the
land by a ratchet and catch. The position of the hoes, in respect to each
other, is regulated by turning the handles at the ends of the axes, carried by
the sockets and lever arms. The lateral position of the whole series of hoes
is regulated by means of an axis, on which there is a pinion which takes into
a curved rack fixed to a bar, which is suspended near the front of the machine.
and which carries the fixed axis on which the tubes (having toothed racks
formed thereon, as before-mentioned,) slide and move.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Naylor in the Great Seal Patent Office on the
17th August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOIN
NAYLOR, of Winterton, near Brigg, Lincolnshire, send greeting.
WHEREAS. Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of February, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Naylor, Her special licence that I, the said John Naylor, my
executors, administrators, and assigns, or such others as I, the said John
Naylor, 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 John Naylor,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 John Naylor, do hereby declare the
nature. of the said Invention, and in what manner the same is to. be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in horse hoes. For theso
purposes each of the hoes is made capable of being moved to and from its
neighbour in order to admit of varying the distances apart of the different
hoes, and the whole series of hoes. in a machine may, as hereafter explained,
also be moved laterally, according to the requirement for the time being.
Each hoe is attached by its stem to a lever arm, which moves independently
of the other lever arnis.. Each hoe has behind it a wheel to regulate the
depth to which the hoe may penetrate into the land. Each of the lover arms
has a short tube or socket at its fore end, which slides on a short tube, which
moves on a fixed axis near the front of the machine, such tube having a
toothed rack formed thereon. Each of the sockets carries a pinion and onc
end of an axis, and such axis at its other end turns in a bearing carried by
the lever arm, to which the socket is attached. The back ends of the lever
arms are suspended by chains to an axis above, in such manner that on
turning the axis by suitable gearing the whole of the lever arms will be
raised, and all the hoes may be lifted out of the land, or the lever arms. may
be allowed to descend to and be retained at any desired position above the
land by a ratchet and catch. The position of the hoes in respect to cach
other is regulated by turning the handles at the ends of the axes carried by
the sockets and lever arms. The lateral position of the whole series of hoes
is regulated by means of an axis, on which there is a pinion which takes into
a curved rack fixed to a bar, which is suspended near the front of the machine,
and which carries the fixed axis on which the tubes (having toothed racks
formed thereon, as before-mentioned,) slide and move.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side elevation; Figure 2 a transverse section; Figure 3
a plan; and Figure 4 a front view of a horse hoe constructed and combined
according to my Invention.
a, a, are the wheels which carry the machinery; these wheels turn on the
axle b, which is fixed to the frame c, c, the nature of which is clearly shown
in the Drawing. At the front of this frame shafts are fixed at c'; c. Below
the frame c is suspended a bar d by means of slings e, one at each end of the
bar d. Below the bar d there is an axis f, having its bearings or supports at
each end of the bar d, as shown. On the shaft or axis f there are as inany

page_text: tubes g as there are hoes. These tubes have toothed racks formed on their
upper surfaces, and the tubes are capable of turning freely on the shaft or
axis f. On each of the tubes g is a socket h, which embraces and is capablo
of sliding on its tube. To the under part of each sliding socket is affixed the
end of a lever i, which carries a hoc or cutter j, and it also has a wheel to
support it, as shewn. Each of the levers i has an axis j* turning in a suitable
bearing, as shewn. At one end of each of the shafts or axis j* is a handle
j, by which it can be turned, and at the other end is a pinion which turns
within a recess formed in the upper part of each of the sliding sockets h; the
upper part of each socket is open to admit of the teeth of the pinion which
revolves therein, gearing with the teeth of the rack on which the socket slides;
hence it will be understood that the position of the lever of any of the hoes
may be moved to or from its neighbouring levers on either side, and the
whole of the levers and hoes are capable of being moved laterally by reason of
the curved rack fixed on the upper side of the bar d, which is acted on by the
pinion on the axis m. The depth at which the hoes or cutters shall work is
regulated by means of chains n, each of which is attached at one of its ends
to a roller or axis o, and the other end of each chain supports one of the axes
j*; and according as the roller is turned by means of the axis p, and bevil
pinions q, q, to wind up or unwind the several chains, so will be the positions
of the hoes or cutters. The roller or axis o is retained from turning by the
ratchet wheel and catch 7, s.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood, that I make no claim to
any of the mechanical. parts separately, nor do I confine myself to the details
shown and described; but what I claim is, the combination herein explained.
In witness whereof, I, the said John Naylor, have hereunto set my hand
and scal, this Tenth day of August, in the year of our Lord Ono
thousand eight hundred and fifty-seven.
