ԹԱԻՄԵՂՍԱՍԱՆԻ
I, THOMAS CHARLES SARGEANT The Limes, Victoria Promenade, Northampton,
Agricultural Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates principally to the box or hopper into which the grain,
manure, or other substance required to be deposited upon the soil is placed. This
box or hopper is constructed as follows. It consists of two ends H. Fig. 1. Fig. 2.
and two sides B. B 1. the bottom being closed by the rotary delivery roller A. Fig. 2
Fig. 3, & the requisite motion being given to this roller A in any desired manner.
The box sides, Baud B 1. are made to vibrate or oscillate upon the centres b, b.1.
This oscillating motion is imparted by a lever G attached to a rocking shaft g.
Connecting rods 1. and 11. one end of each jointed to pins g.2, g 1, are placed upon
the lever G, above and below the rocking shaft g. The other ends of the rods I, II,
are coupled to pins 63 62. upon the upper edge of the vibrating sides. It will
therefore be seen that as the lever G, rocks upon the shaft g, the box sides B, B1
are compelled to advance and retire. The object of this motion is to compel sticky
substances to fall to the bottom of the box. The rocking shaft g, runs beyond the
length of the box and parallel with the delivery roller A. The rods I, 1 1, and
pins g 1, 2, 62, 63, may thus be in duplicate triplicate &c. L is a slide capable
of vertical adjustment on the vibrating side B 1, the lower edge of this adjustable
slide being inclined towards the delivery side of the feed roller A. The object of
this adjustable slide is to regulate the supply of manure &c., to the feed roller A.
An adjustable gate k, radiates on the centre b, and is regulated by the thumb
nut 1. The gate is kept in the desired position by the spring K, pressing upon
the arm k 2. This spring is in compression and therefore keeps the gate opposed
to the contents of the box. The object of the gate is to release any stones or hard
substance which may get into the box.
The box is also fitted with adjustable partitions M. M 1. Fig. 4, capable of
horizontal adjustinent for the purpose of varying the width of the rows. These
partitions are in two pieces, and are attached to the vibrating sides B, B1. The
edge of each half partition M, projects beyond the edge of the other half M 1. in
order that the vibratory motion of the sides to which they are secured may be
imparted to the partitions. These adjustable, detachable partitions are used when
the contents of the box is to be deposited in rows upon the soil, in which case only
that manure &c. contained between the two pairs of partitions, would come in
contact with the delivery roller A.
I further attach to the delivery roller shaft to prevent straining the said shaft, a
friction clutch consisting of two plates with corresponding teeth on each face Fig. 5.
The said teeth are opposed to each other, the active edges tapering from the face
of the plate, that is the active edge of each tooth describes an angle greater than a
right angle with the face of the plate, so that when an undue strain is put upon the
shaft, the teeth of the two plates become disengaged. These plates are pressed
together by a spring, the strength of which determines the gripping power of the
clutch.
A series of rings J fitting loosely upon the delivery roller A with projections

page_text: formed upon the said rings extending. across the path of the said teeth of the
roller A scrape off any substance adhering to the teeth.

An Agricultural Drill and Distributor.
1, THOMAS CHARLES SARGEANT, of The Limes, Victoria Promenade, North-
ampton, Agricultural 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 certain improvements in agricultural drills. and
distributors the improvements relating to the box or hopper which holds the grain,
manure or other substance required to be deposited on the soil and to parts more or
less immediately connected therewith.
To clearly explain my invention reference is made to the accompanying drawing
in which
Fig. 1 is a sectional elevation of the hopper and connected parts.
Fig. 2 is an end view of same.
Fig. 3 is a sectional elevation of the friction clutch hereafter referred to.
Fig. 4 is a face view of one of the parts of same and
Fig. 5 is a side view of the part.
In the above drawings the invention is illustrated in connection with a
"distributor" or machine for depositing manures or other substances upon the soil
either in rows or broadcast, one of the objects aimed at being to compel the
contents of the hopper to fall down into contact with the delivery roller which in
the case of sticky compounds is sometimes found difficult.
a
To this end the box or hopper is provided with two ends 1. 2 supported by a
suitable framework the two sides 3. 4 being pivoted to the ends at the points 5.5"
the roller 6 partially closing the bottom opening. Adjustably attached to the
inside of the side 3 by screws and. slots, or in other ways is a plate 7 carrying
hinged regulating plate 8 the lower edge of which is supported by the roller 6 the
position of this regulator and the position of the gate hereafter described
determining the amount of the contents of the hopper to be exposed to the roller 6
and thus the quantity of manure or other substance deposited..
A gate 9 is also pivoted to the point 5* such gate being controlled' by an arm 10
through one end of which passes a rod 11 carrying an adjustable spring 12 the
other end of the rod being hung on a stud 14 supported by the ends 1. 2. The
arrangement enables the gate to open outwards in order to release any hard
substance that may pass over the roller, the pressure of the spring determining the
amount of resistance to the contents of the hopper. Supported in suitable
brackets 15 is a rocking shaft 16 which may be operated by any suitable means
but preferably by the arm 17 to which is attached a rod 18.adjustable in respect
thereto such rod being operated by an eccentric 19 carried by a spur
wheel 20.
The rocking shaft. 16 carries at one end a double crank 21, while the arm 17 and
extension 22 thereof serve the same purpose at the other end. To these parts 21,
17 and 22 are connected crank rods 23, 23, 24, 24. These rods carry stude 25.
which pass through slots 26 in the ends 1. 2 and carry short arms 27 attached to
the sides 3. 4 by which means the sides are. reciprocated so as to shake down the
material between them.7
The hopper may be provided with a number of partitions 28, 29 attached to the
sides 3.4 respectively and overlapping each other in the centre sufficiently to keep
the division intact at the widest expansion of the hopper. These partitions are for

page_text: the purpose of enabling the hopper to be divided up so that the contents can be
distributed at intervals along the roller or different materials be delivered at the
same time.
The partitions may be removeable and adjustable so as to be set to different
widths if desired.
The spur wheel 20 is driven by a spur wheel 30 (Figs. 2 and 3) which forms part
of a friction clutch on the shaft 31 of the roller 6 the object of which is to drive.
the delivery roller without allowing undue strain to be put on same.
This friction clutch consists of the spur wheel 30 which is driven by the gear 32
on a shaft which is driven in some suitable way from the road wheel of the machine.
The spur wheel 30 is recessed and carries a circular rack 33 the teeth of which are
formed with their faces at an obtuse angle or such a one that they will easily engage
with or ride over the teeth on a plate 34 (Figs. 2, 3, 4 and 5). This plate has
openings 35. 35 therein through which project studs 36. 36 on a plate 37 attached
to a tube or socket 38 having a squared opening in which is secured the shaft 31
such socket passing through a bushing 39 attached to the spur wheel 30. The
plate 34 is kept pressed to the rack 33 on the spur wheel 30 by a suitable spring
such as 40 which causes the teeth of the two parts to engage, the strength of the
spring determining the gripping power of the clutch. It will be seen that the spur
wheel 30 when the parts are in the position shown in Fig. 3 is driving the shaft 31
through the teeth 33 and plate 34 which rotate through the studs 36 the plate 37
and socket 38 but that any extra strain on the shaft 31 will cause the teeth of the
rack 33 to ride over the teeth of the plate 34 when the latter will not be driven.
In the place of causing both the sides to vibrate one of them may be fixed and the
other vibrate.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an agricultural drill or distributor a hopper provided with fixed ends, and
a side or sides capable of a shaking movement substantially as and for the purpose
described.
2. In combination a hopper provided with fixed ends, and a side or sides capable
of a shaking movement, means for partly closing the bottom of said hopper and a
yielding gate for controlling the discharge of the material substantially as and for
the purpose described.
3. In combination a hopper provided with a side or sides capable of a shaking
movement a roller beneath same and a regulating plate and gate for controlling
the discharge of the material from the hopper substantially as and for the purpose
described.
4. In combination a hopper provided with a pivoted side or sides, crank rods
connected to the pivoted side or sides and means for vibrating the crank rods
substantially as and for the purpose described.
5. A friction clutch for controlling the delivery roller of a machine such as
described consisting of the spur wheel provided with circular rack, a spring-
pressed plate having teeth engaging with the rack, a second plate driven by
the first plate and a shaft driven by the second plate substantially as described.
6. The improved construction and arrangement of parts for an agricultural drill
or distributor substantially as described and illustrated.
