Complete Specification. Left, 22nd Sept., 1899-Accepted, 11th Nov., 1899
THOMAS CHARLES SARGEANT, 1, Victoria Promenade, Northampton, Engineer,
do hereby declare the nature of this invention to be as follows:-
My inventions consists in a combination of parts so arranged as to facilitate the
movement of the hopper and shield of machine made under my Patent
No. 24537/97. In suitable bearings attached to. the main frame (one on each side)
revolves a shaft, the said shaft occupying a position parallel to the axis of the
revolving spreader. To each end of the said shaft I attach a crank one end of a
pair of connecting rods connect the said cranks to the radial arms to which the
hopper is jointed, a pair of links or rods, one end of which are jointed to the
shield while the other or lower ends are jointed to the aforesaid connecting rod
so that one half revolution of the crank-shaft elevates the hopper and lowers the
shield while the other half revolution of the said crank shaft lowers the hopper and
elevates the shield. This arrangement of gear bringing about the desired move-
ment of the hopper and shield by allowing the hopper to descend at a greater
speed than the shield ascends at the commencement of descent of the hopper.

I, THOMAS CHARLES SARGEANT, of 1, Victoria Promenade, Northampton, in the
County of Northampton, Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to an improvement in the means for operating the drum
or shield and hopper of a type of distributor described in the Specification to my
Letters Patent No. 24537 of 1897.
The object of the present invention is to be able to effect the movements required
for bringing the hopper into the filling position and lowering it into the position
in which it is ready to start the distributing by one movement of a lever for each
operation the means for keeping the hopper subsequently drawn up by the chains
and pulleys forming no part of my present invention. These movements of
raising and lowering the hopper and moving or rotating the shield have hitherto
been done separately with the result that should by accident the movement of
rotation of the shield or drum be done first the manure is deprived of its support
in the hopper on one side and will fall through onto the ground.

page_text: According to my invention the parts are so arranged that the movements are
timed in their proper order and each is effected from a single point by a lever or
hand wheel.
In the accompanying drawing
Fig. 1 is an elevation of sufficient of a distributor to illustrate my invention.
Fig. 2 is a similar view with the parts in another position, and Fig. 3 is a plan
of the operating hand wheel.
a is the axle of the vehicle, on which is mounted the spreader wheels b, which
are driven by the movement of the vehicle wheels c. d is the shield or drum,
ande is the hopper. The axle d is carried by a frame f, to which the shafts are
attached. To the axle a I hang an arm or lever g, which is loose on same but is
pivoted to the lowest point of hopper e. To said arm is attached a link fixed to
a crank on a shaft's supported by the frame and capable of turning thereon.
To the link is pivoted about midway a second link pivoted in turn to the
outside of the shield or drum d and preferably to the shaft j which forms part of
the mechanism for operating the chain for raising the hopper when distributing,
one of the pulleys over which such chain passes being indicated at k as carried on
a stud to which is attached a slotted guide link which surrounds the axle a and
acts as a guide for the hopper when it is being closed up during the distributing.
These parts j k l however form no part of my present invention. The crank i is
connected solidly with a disc m (Fig. 3) which may have ratchet teeth formed
on the inside together with two stop notches m¹ m¹ if desired to mark the different
positions. A spring pawl n controlled by a handle o may engage with these teeth
so that the disc may only be turned if desired (which is done by its handles 2) in
one direction. The pawl may be arranged to fall completely into the stop
notches mm so that it will have to be lifted out by the handle o before the
ratchet can be turned so that the two positions of the parts are marked by these
notches which enables it to be known when the parts have been moved sufficiently
far.
In Fig. 1 the parts are in their filling position the manure being thrown into the
open top of the hopper e and receiving a curved shape from the other side of the
drum or shield d. The handle being turned the link is moved in a rearward
direction rotating the arm g and hopper e, until the latter falls downward on its
guiding link into its feeding position as shewn in Fig. 2. The movement of
link exerts no effect on link while link h is moving downwardly so that the
drum d is not moved in the first instance except it be perhaps very slightly
upwards but as soon as arm g passes the vertical position and commences to rise,
the links h and are quickly raised thus rotating through the latter the drum or
shield d and raising it into the position shewn in Fig. 2 where it will be seen that
it has fully exposed the spreader wheels 6 so that they are enabled to act on the
contents of the hopper as the latter is drawn up and throw it through the opening q
left between the lower edge of the drum and the upper edge of the hopper. It
will be understood that there is a corresponding arrangement of links and levers
on the other end of the machine.
By this arrangement of parts it will be seen that it is impossible for the drum
to be moved first thus taking away the support for the manure in the hopper while
the movement just described takes place with one movement of a handle while
a further movement of the handle will bring all the parts back to their original
position the shield being lowered as the hopper is raised to meet it.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a manure distributor, a drum or shield, a moveable hopper, one side of
which is formed in its filling position by the face of the shield, and means for
moving said hopper from its filling position to its feeding position and for subse-
quently and as part of the operation moving said shield to expose the spreading

page_text: device, such means being operated by a handle or the like from one point sub-
stantially as and for the purpose described.
2. In a manure distributor, the combination with a shield, and a hopper capable
of a radial movement around the shield, of a lever carrying the hopper, a crank,
a link connecting said lever and crank, a second link connected to the first and
to the shield, and means for rotating the crank whereby the hopper may be first
moved from its filling position and the shield next moved to expose the spreading
devices substantially as described.
2. The improved distributor for agricultural purposes substantially as described
and illustrated.
