IMPROVEMENTS IN HORSE HOES
Year: 1856

page_text: LETTERS PATENT to Alfred Priest and William Woolnough, of the
Iron Works, Kingston-on-Thames, for the Invention of "IMPROVEMENTS
IN HORSE HOES."
Sealed the 30th January 1857, and dated the 14th August 1856.
PROVISIONAL SPECIFICATION left by the said Alfred Priest and William
Woolnough at the Office of the Commissioners of Patents, with their
Petition, on the 14th August 1856.
We, ALFRED PRIEST and WILLIAM WOOLNOUGH, of the Iron Works,
Kingston-on-Thames, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN HORSE HOES," to be as follows:-
This Invention has for its object improvements in horse hoes, made with
hoes or cutting parts affixed to stalks and levers, rising and falling indepen-
dently of each other. In such horse hoes as at present constructed, the bar on
which the hoe levers are mounted and turn is suspended from the frame by
links or jointed irons, and when the hoes are moved towards one side or the
other, to steer them between the rows of the crop they are raised more or less
out of the ground, in consequence of the inclined position taken by the links or
jointed irons, thus causing inequality of work and difficulty of steerage.
Now, our Invention consists in mounting the bar which carries the hoe
levers in such a manner that it can be moved from side to side without alter-
ing its distance from the land, and so that the hoes or cutting parts may
always be kept at a uniform depth. For this purpose two vertical axes or

page_text: standards are employed, one on each side of the frame, and on these axes or
standards are cranks or armis, to which the bar carrying the hoe levers is
connected.
The Invention also consists in arranging the bar which carries the hoe
levers in such a manner that its distance from the land can be adjusted while
the boe is travelling; first, to set the hoes or cutting parts in a more or less
oblique position, as the hardness of the ground or nature of the work may
render necessary; and, secondly, as the arrangement admits of either one or
both ends of the bar being raised or depressed at pleasure, sloping ground or
side hills may be hoed with equal precision in depth as on the flat. For this
purpose the axes or standards, to which the ends of the bar are attached, a
capable of being moved up or down in the frame at either. end, by means
of suitable lifting apparatus provided for the purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Priest and William Woolnough in the Great Seal
Patent Office on the 14th February 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALFRED
PRIEST and WILLIAM WOOLNOUGH, of the Iron Works, Kingston-on-Thames,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of August, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Alfred Priest and William Woolnough, Her special licence that we, the said
Alfred Priest and William Woolnough, our executors, administrators, and
assigns, or such others as we, the said Alfred Priest and William Wool-
nough, our exccutors, 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 we, the said Alfred Priest and
William Woolnough, our executors or administrators, by an instrument in
writing under our or their hands and seals, or under the hand and seal of one
of us or them, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause

page_text: 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 we, the said Alfred Priest and William Wool-
nough, do hereby declare the nature of the said Invention, and in what
manner, the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say:-
This Invention has for its object improvements in horse hoes, made with
hoes or cutting parts affixed to stalks and levers, rising and falling indepen-
dently of each other, and consists in arranging the bar which carries the hoe
levers in such a manner that its distance from the land can be adjusted while
the hoe is travelling; first, to set the hoes or cutting parts in a more or less
oblique position, as the hardness of the ground or nature of the work may
render necessary; and, secondly, as the arrangement admits of either one or
both ends of the bar being raised or depressed at pleasure, sloping ground or
sile hills may be .hoed with equal precision in depth as on the flat. For this
purpose the axes or standards, to which the ends of the bar are attached, are
capable of being moved up or down in the frame at either end, by means of
suitable lifting apparatus provided for the purpose:
And in order that our Invention may be most fully understood and readily
carried into effect, we will proceed to describe the Drawings hereunto
annexed.
⚫ DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a plan, Figure 2 a transverse section, and Figure 3 a
front end view, partly in section, of a horse hoe constructed according to our
Invention. a, a, are the hoe levers, to which the stems or stalks a', which
carry the hoes or cutters a², are attached. The levers a are connected to and
move on pin joints at a³, a³, carried by the bar b. 61, 61, are arms on the bar b,
upon which friction rollers are mounted, and are supported in boxes formed at
the lower ends of the vertical axes or standards c, c; one of the arms b¹ is
connected by a link 63 to the lever arm 63, fixed on the horizontal axis 6+,
supported in bearings 6. Fixed to the framing 6, 66, are lever arms on the end
of the axis b, by which the bar 6 and hoe levers may be moved from side to
side, in order to adjust the hoes to the rows of crop, without altering the depth
of the hoes or cutting parts on either side. The vertical axes c, c, are supported,
and are capable of moving up and down in the sockets c¹, c', fixed to the
framing of the machine, and when it is desired to raise or lower the bar b, to
which the hoe levers are connected, it is accomplished in the following
manner :- d, d, are levers, moving on fulcrums d', carried by the parts c³ of

page_text: the sockets c; the curved ends of the levers d, d, pass through slots formed
in the vertical axes or supports c, c, and when the levers d, d, are pulled
downwards the curved ends of the levers act against friction rollers carried by
the vertical axes or supports c, c, and thus raise the vertical axes or supports
c, c, in their sockets c', c', and they are retained in any desired position by the
spring pauls d³, d, which take into the ratchet teeth formed on the parts c³, c³,
of the sockets c', thus it will be seen that the bar b may be raised or lowered
whilst the hoe is travelling in order to adjust the hoes or cutting parts, and set
them in a more or less oblique position, as circumstances may require; and also
that either end of the bar b, may be raised or lowered independently of the
other, so as to adjust the hoes or cutting blades to penetrate a uniform depth,
whether on hilly ground, side hills, or ridges, whether one wheel runs in the
furrow and-the-other-on-the land. e is a lever fixed on the cross axis e¹, upon
which excentrics e² are fixed, and chains are attached at one end to the
excentrics e and at their outer ends to the bar e, upon which the ends of
the hoe levers a rest, and by this means they may be raised completely off the
land.
havo
Having thus described the nature of our said Invention, and the manner
of performing the same, we would it understood that we do not confine
'ourselves to the exact details described; but what we claim is, the so arranging
horse hoes with hoes rising and falling independantly of each other, that the
bar which carries the independent hoes may be raised or depressed at either
end while the implement is in motion, so as to place the bar and hoes in an
inclined position to suit the land, as herein described.
In witness whereof, we, the said Alfred Priest and William Woolnough,
have hereunto set our hands and seals, this Twelfth day of February,
in the year of our Lord One thousand eight hundred and fifty-seven.
