I, WILLIAM SARGEANT, of Bradfield-on-the-Green, Northamptonshire,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF HORSE-HOES AND SEED DRILLS," to be as follows:-
This Invention relates to improvements in the construction of horse hoes,
and seed or other drills, whether the same are separate or combined imple-
ments, and consists in improved arrangements of the frame and carriage,
together with the mode of steering the same when in use, and in drawing
it along when travelling out of use. For this purpose I mount the fore-
part of the carriage upon wheels on each side, capable of being controlled
in their movements to the right or left by suitable steering apparatus
actuated from the hinder part of the carriage. The front steering wheels
are carried by and revolve on arms which are cranked at their lower ends,
the upright parts of such arms passing upwards through the front part of
the carriage frame, and being capable of adjustment therewith in order to
raise or lower the operating parts when required. On the upper ends of
the upright arms which carry the steering wheels levers are fixed, which
are extended towards the hind part of the implement, and are there con-
nected by a cross bar which serves as a hand lever to govern the direction
of the fore wheels from either side of the implement according to the side
on which it is operating when its direction is reversed.

page_text: The hind part of the carriage frame is (by preference) supported and
carried by a single central wheel mounted upon a forked cranked arm, the
upright part of the arm passing upwards through a metal socket on the frame,
and being free to revolve therein, and the arm has a collar thereon upon
which this end of the frame is supported. The bind wheel by being
mounted on the cranked arm permits the direction of the implement being
readily reversed in a very small compass by causing it to rotate on a centre
formed by one of the front wheels remaining stationary, but when in use the
upright arm is keyed fast to the frame to cause the wheel to travel in a direct
line, the draught bar and harness being placed in front. When the imple-
ment is out of use, and is being moved from place to place, shafts and draught
are applied to the hinder part of the carriage frame, the key being removed
from the upright arm so as to allow the hind wheel to assume various posi-
tions in accordance with the direction in which it is being drawn. The cross
bar and front steering apparatus are fixed to the frame for the time being
by a pin, or otherwise, the steering wheels previously described acting for
the time as hind wheels. In place of employing a single wheel at the binder
part of the carriage two wheels mounted and arranged one on each side with
the capability of changing their position with the direction of the carriage
may be employed; but I prefer the arrangement first described. Suitable
driving gear is applied to one or both of the axes of the front wheels to
communicate motion to the drill box apparatus which is mounted on the
carriage frame and is of the ordinary character.
The mode of arranging and mounting the hoes and levers for actuating
them is also such as is well known and forms no part of my present im-
provements.
