Fig. 6 a side elevation showing a mode of operating the apparatus.
The cylindrical metallic casing (a) is secured upon the shaft (6) by the set pin (6')
in the boss of the disc plate (c) which forms a cover for the casing and is secured
thereto by bolts (d).
The inner cylinder (e) fits within the outer casing and is secured upon a tube (f)
surrounding the shaft (6) and provided with a screwed end (g) taking into a nut (h)
in the operating wheel ().
The nut () is held in position by a flange (5) upon one side of the
cover (c) and by the boss (k) of the wheel (i) in which it is secured by a pin (l).
Holes (m) preferably of a diamond shape, with a small circular hole (n) for
small seeds at one point of the diamond, are provided at regular intervals in the
casing (a) and holes (m') corresponding in position but preferably rectangular
in shape and small circular holes (n) corresponding with the holes (n) are formed
in the inner cylinder to correspond with the similarly shaped holes in the outer
casing. By turning the operating wheel the tube carrying the inner cylinder is
moved longitudinally upon the spindle (b) and the size of the holes (m) regulated,
or, the small holes in the inner and outer cylinder brought into correspondence ns
desired.

page_text: Semi-circular cups (o) fixed upon the inner periphery of the cylinder (e)
around each of the holes therein are designed to carry seed and prevent the
holes from choking from over pressure. Rings (p) formed of sheet metal and
V shaped in section are fixed within the cylinder (e) dividing it longitudinally
into compartments whereby the seed is deflected towards the cups as the cylinder
revolves.
A circular opening (r) for admission of seed is closed by the cover (²) pivoted
upon a pin (r2) and secured by a wing nut (3) upon a screw pin (r 4) taking into
a jaw formed upon the cover.
Studs (s) and (u) secured upon the inner cylinder take into slots (t) and (u 2)
in the outer casing; and ensure that they revolve together and maintain the cylinder
in position within the casing so that the holes with which they are respectively
provided are in line.
A semi-circular index plate (u) is fixed to the outer casing and the stud (¹)
fixed to the inner cylinder working in the slot (u 2) in the casing engages with a.
slot (u 3) in the pointer (u 4) which is pivoted at one end its opposite end travelling
over the index plate and indicating the relative positions of the cylinder and casing
and consequent size of the apertures through which the seed passes.
In operation, the distributor is revolved in the direction of the arrow (Fig. 5) from
a sprocket wheel (v) upon the axle of the implement connected by the chain (¹)
with a sprocket pinion (v2) on the shaft (b).
Seed placed within the cylinder alternately falls into and out of the cups (o) as
the apparatus revolves, a certain quantity, according to the nature of the seed,
being delivered through the holes when they respectively arrive at about the position
shown in Fig. 5.
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. A seed distributor consisting of a cylindrical casing provided with holes in its
periphery fitted with an inner cylinder which revolves with it and has corre-
sponding holes; the inner cylinder being adjustable longitudinally whereby the
holes therein may be brought into correspondence with the holes in the casing
or the holes in the casing partly or entirely closed substantially as specified and
illustrated.
2. In combination, the cylindrical casing (a) secured upon the shaft (b) and
having holes in its periphery, an inner cylinder (e) having corresponding holes and
seed cups (o) being fixed upon the tube (f) surrounding the shaft (b) upon which
it is capable of longitudinal adjustment by a nut (h) working upon the screwed' end
of the tube (f) and operated by a hand wheel (i). The cylinder (e) being caused
to revolve with the casing (a) by one or more studs secured to the cylinder taking
into slots in the casing substantially as and for the purposes herein described and
illustrated.
3. In combination, the casing (a) upon the shaft. (b), the inner cylinder (e)
upon the tube (f) having compartments formed by the rings (p) and being provided
with seed cups (o) substantially as specified and illustrated.
4. The semi-circular index plate upon the casing (a), the latter having a
longitudinal slot receiving a pin attached to the inner cylinder, such pin engaging
in a slot in a pointer which is thereby operated substantially as and for the purposes
herein described and illustrated.
