I, WILLIAM SARGEANT, of Brafield-on-the-Green, in the County of
5 Northampton, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF HORSE-HOES AND SEED OR OTHER 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 hinder
part of the implement, and are there connected 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

page_text: direction is reversed. 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 hind 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 positions
in accordance with the direction in which it is being drawn. The cross bar
and front steering apparatus is 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 hinder 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.
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 of the ordinary
construction mounted upon the carriage frame, and part of my Invention
consists in an improved mode of mounting the driving wheel which com-
municates motion to the drill box apparatus upon a tube or hollow axle,
which revolves on the axle of the implement in place of connecting such
driving wheel to the hub of the travelling wheel, which in my improved
arrangement is capable of adjustment upon the hollow axle to vary the width
apart of the steerage wheels without altering the position of the driving wheel
which actuates the drill box apparatus.
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
improvements.
