System by the Reciprocating Circular Action of a Bladed Disc,
Applicable also for Distributing Fertilisers, Manure, and the
like.
I PERCY LANKESTER, of 44, Sumner Street, Southwark, Surrey, Engineer do
hereby declare the nature of my said invention to be as follows:-
--
The object of this invention is, an arrangement of appliances by which seed or the
like can be distributed by a reciprocating circular motion imparted to a bladed disc by
a to and fro motion of a rod or hand bar to which a cord is attached and wrapped
round a reel by which the bladed disc is carried, the spindle of said reel and disc
being fitted loosely in a frame, the upper part of which provided with a tongue or
sliding plate aperture for regulating the supply of material to the distributing disc
from a bag or other receptacle in which seed or the like is temporarilly placed.
The frame is provided with a shoulder or sling strap by which the article can be
carried by a man, who, after regulating the size of the opening for the passage of the
grain or seed, draws the hand rod to and fro, the wrapped cord of which causes the
disc to rapidly rotate first in one direction and then in the other but horizontally so
as to distribute the grain evenly before him with a wide spread sideways.
The hand rod may have a spring fitted on either side to give a rebound to reduce
hand labour.
I fit a shield at tho back part of the opening in which the bladed disc works.
The invention is applicable for Sowing wheat, Barley, Oats, Rye, Rice, Flax, Grass
Seed and other, and also Fertilisers say Bone dust or it may be manure, such as
Guano.

System by the Reciprocating Circular Action of a Bladed Disc,
Applicable also for Distributing Fertilizers, Manure, and the
like.
I, PERCY LANKESTER, of 44 Sumner Street, Southwark, Surrey, 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:-
The object of this invention is an arrangement of appliances by which seed, or the
like can be distributed by a reciprocating circular motion imparted to a bladed disc by
a to and fro motion of a rod or hand bar to which a cord is attached and wrapped
round a reel, by which the bladed disc is carried, the spindle of said reel and disc being
fitted loosely in a frame, the upper part of which is provided with a tongue or sliding
plate aperture for regulating the supply of material to the distributing disc from a
bag or other receptacle, in which seed or the like, is temporarilly placed.
The frame is provided with a shoulder or sling strap, by which the article can be
carried by a man, who, after regulating the size of the opening for the passage of the
grain or seed, draws the hand rod to and fro, the wrapped cord of which causes the
dise to rapidly rotate first in one direction and then in the other but horizontally so
as to distribute the grain evenly before him with a wide spread.
The hand rod may have a spring fitted on either side to give a rebound to reduce
hand labour.
I fit a shield at the back part of the opening in which the bladed disc works.
My invention is clearly shown in the accompanying drawings in which Figure 1 is
a side elevation and Figure 2 a plan. Figure 3 is a view looking at the underside of
the box or trough, in which the seed is placed and Figure 4 a detailed view on a large
scale of the reciprocating circular motion blades with a two stepped pulley, on which
the cord can be wrapped to regulate the speed at which the blade shall be operated
and also the distance to which the seed shall be spread.
The apparatus is composed of a trough A forming the bottom part of a sack B for
containing the seed, grain, or other substance to be distributed the apparatus being
suspended from the shoulders of the man by the strap C, the edge strip D resting
against the man's side to steady the apparatus and to give him a good purchase for
moving the hand rod to and fro in front of him.
The bottom of the box A has an aperture E near the front, through which the grain,
or other substance may pass, the opening of which is regulated by a hand lever F
capable of being fixed in the required position by a fly nut G and bolt, said bolt being
fixable at any part of the race H for that purpose.
The hand lever F, shown more clearly in Figure 3, is connected by a link I to a
sliding plate, the front end of which carries a shutter J to close the opening E more
or less as determined by the position of the hand lever F.

page_text: Within the aperture E a couple of agitators K, K, are arranged as projecting from a
plate L, which has a to and fro, or segmental travel due to the excentric M, which is
on the spindle of the reciprocating circular motioned blades or distributors N, the
plate L being centred from the pin P.
The blades or distributors N surmount a double, or two step pulley Q, R, and
being pivotted in the top frame S and the lower frame T, it has a circular reciprocating
action imparted to it by the wrap of the cord U which may be upon the pulley Qor
the pulley R according to the speed at which the bladed distributor N has to rotate,
this being effected by means of the hand rod V by manual power.
W, W, are springs attached to the side of the bottom frame T, so that the springs
are alternately compressed by the shoulders X of the hand rod V at each to and fro
travel and assist to return the hand rod V by their rebound which considerably reduces
the labour in drawing the rod to and fro.
Y is a segmental plate to prevent the grain striking the man should any bo flirted
backwards but in practice this very seldem happens because the grain is received by
the bladed distributor from the rear of its centre or pivot point consequently the
centrifugal action which distributes the grain does not come into action until the
blades have travelled beyond the projecting ends of the back of the guard Y.
I have shown the pulley with two steps Q and R only but it may have three or
more, or the pulley may be cone shaped and by the adjustment of two small rollers
affixed to the bottom frame T, the wrap of the cord U may be determined to act upon
the desired part of the cone.
The invention is applicable for sowing wheat, barley, oats, rye, rice, flax, grass seed,
and other, and also fertilizers, say, bone dust, nitrate of soda or it may be manure
such as Guano.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed' I declare that what I
claim is :-
The general construction and arrangement of portable apparatus to facilitate seed
sowing on the broadcast principle with a reciprocating circular action of the bladed
disc which can be driven at the required speed by shifting the cord from one pulley to
another of the same spindle, or from one part of a cone to another as described and
shown with reference to the accompanying drawings.
