page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement :—
This invention relates to that class of fertilizers or manure distributers in which
the material to be distributed is placed in a hollow revolving drum or cylinder and
is discharged therefrom through a series of openings in the periphery of said
cylinder and particularly to the devices for measuring and discharging the material
and it consists in certain novel features of construction arrangement and com-
bination of parts which will be readily understood by reference to the description
of the drawings and to the claims to be hereinafter given.
In the accompanying drawings

In the drawings A is the axle, B the wheels, C the pole or perch and D, D¹, two
hexagonal hollow drums to receive the material to be distributed all arranged,
connected together and operated in any well known manner.
The hexagonal drums D D' are each provided with a series of receiving and
discharging chambers each composed of the outer plate E having formed near one
end thereof a bend in the form of two frusto-conical semi-tubes a and a¹ with their
small ends joined, the bucket like casting E' secured to said plate E and fitted to
and projecting through an opening cut through the shell of the drum D, the
adjustable double inclined or V-shaped plunger F and the inwardly projecting
ledge G cast upon the inner face of the plate E and having a width equal to about
two thirds of the depth of the casting E as shown in Figure 6.
The plate E has formed in its inner face the shallow groove b to receive and
guide the shank or stem c of the plunger F and with the slot d to receive the
shank of the screw e firmly secured in the plunger F preferably by casting the
metal around the head of the screw, said plunger being clamped in any desired
position by means of said screw and the thumb nut e¹ as shown in Figures 3 and 5.
The stem c of the plunger F extends inward beyond the apex of the V-shaped
face of said plunger and through an opening in the plate or ledge G as shown in
Figures 5, 6 and 7.
The plate E and the bucket E¹ are secured together by suitable rivets f, for
other similar means and the whole is secured to the drum D by the screws 9, 9, 9
all as shown in Figures 3 and 5.
The stem of the plunger F has formed upon its upper side a rib which fits into
the slot d in the plate E and has formed upon its upper side a transverse rib or
index projection h which in connection with the Figures formed upon the plate E on
each side of the slot d serves as a means of determining the proper position of the
plunger to deliver a given quantity of material.
The casting E¹ has formed in opposite sides thereof and just inside of the
peripheral wall or casing of the drum D, two rectangular openings i, i, through
which the fertilizing material enters the bucket between the inclined faces of the
plunger F and the ledge it being directed thereto by the oblique ledges H H
secured to the inner surface of the drum casing as shown in Figure 4.
The measuring, receiving and discharging buckets are arranged in circum-
ferential rows around the drum there being just half as many buckets in each row
as there are flat sides to said drum, and the buckets in one row alternating with
the spaces in the next row as shown in Figure 1.
The bucket E¹ has its closed end inclined at an angle of about forty five degrees
to the inner face of that side of the drum casing to which it is secured as shown in
Figure 5.
The perch, or pole C, may be clamped or secured to the axle A by any well
known means but I prefer to clamp the same to the axle by means of the cap j
strap and bolts j², ja.
The drums D D₁ are made preferably of metal with wooden heads D2 D2 the
centres of which are provided with suitable metal, bearings which are fitted to and
revolve about the axle A all as will be readily seen by reference to the drawings.
The castings A¹ which form the centre of the outer heads of the drums D and D¹
each has formed upon its periphery a series of ratchet teeth 8, 8 with which the
pawl s engages to impart to said drum a rotary motion about the axle A upon
which it is mounted.
>
The pawl s' is pivotted at s³ to a stand B¹ secured, to the spokes s³, 83 of the
wheel B by the screws 8, s and forced into contact with the teeth 8, 8 by the
springs placed between it and the lug se projecting from the stand B¹ as shown in
Figures 10 and 11,

page_text: The stand B¹ has formed upon its end opposite to the lug sa hub or boss 87,
in which is mounted a short shaft 88 having secured upon one end thereof the
cam in position to act upon and depress the arm 810 of the pawl s¹ to disengage
said pawl from the teeth s, 8 and provided at its other end with the milled head or
collar B by which said shaft and cam may be rotated.
Each of the drums D D¹ is provided with an opening in its periphery closed by
any suitable cover D³ said opening being for the purpose of charging the drum
with the fertilizing material to be distributed.
The machine illustrated in the drawings is designed to be connected by the
perch C to a forward axle, not shown, but said perch may be so constructed as to
serve as a pole to which a pair of horses may be harnessed without affecting the
principles of this invention.
The operation of my invention is as follows.
The drums D D being suitably charged with the material to be distributed and
the pawls s, & being thrown out of engagement with the teeth 8, 8 the machine
may be driven to the ground to be enriched, when the pawls being allowed to
engage with the teeth 8, 8 so as to compel the drums to revolve with the wheels,
if the machine be driven over the ground said drums are revolved and the
fertilizing material, such as ground bone will be discharged from the larger end of
the conical semi tubes a and a¹ at each side of each plate E, in a steady stream and
be deposited upon the ground in parallel rows the distance apart of which will be
determined by the width of the plate E or the combined length of the conical
semi tubes a and a¹ and the longitudinal distance a part of the circumferential rows
of buckets.
The drums D D revolve in the direction indicated by the arrow on Figures 2
and 7.
As the fertilizer naturally falls to the lower side of the drums the buckets which
are at or near the bottom are completely buried by the fertilizer which completely
fills the angle between the inclined ledges H H and the sides of the buckets E¹
and partially fills the space between the inclined faces of the plunger F and the
ledge G.
As the drum revolves in the direction indicated by the arrows on Figures 2
and 7 and the bucket assumes the position indicated at the lower right hand
portion of Figure 7 the fertilizer that lies between the inclined ledges H H and
the sides of the bucket slides down said inclines and through the openings i, i to
increase the quantity of fertilizer in the chamber between the inclined surfaces of
the plunger and the ledge G and nearly fill said space as indicated at k.
When the bucket has assumed the position shown at the upper right hand
portion of Figure 7 any fertilizer carried upward by the inclined ledges and that
has not found its way into the bucket will fall therefrom to the bottom of the
drum and the material within the bucket will have assumed the position indicated
by the tinted surface at land in like manner, as the drum revolves and the bucket
assumes the positions at the top-upper left hand, lower left hand and bottom
portions of Figure 7, the material contained in the bucket assumes successively the
positions indicated by the tinted surfaces m, n, o and p, said material beginning
to be discharged from the semi tubular passages when the bucket reaches the
point q on Figure 8 and continues to be discharged until the bucket reaches the
point in the revolution.
The material first fills that portion of the space between the plunger F and the
ledge or partition G contiguous to the casing of the drum and extending inward
as far as the inner sides of the openings i, i, then as the drum revolves it falls to
the inner side of said space, then slides along the bottom or inner wall of the
bucket beneath the partition G towards the inclined end wall of the bucket along
said inclined wall to the semi-circular flaring discharge tubes where the mass
divides and by virtue of the varying angle of incline of the walls of said tubes, it
will be delivered from the larger ends of said tubes in a continual stream during
the passage of the bucket from the point q to m on Figure 8 as before described.

page_text: The amount of material that will be delivered from a single bucket may be
varied at pleasure by adjusting the plunger F to a greater or less distance from
the ledge G which may be done by simply slackening the nut el moving the
plunger in or out till the index rib or projection h coincides with the number
standing for the amount required to be discharged.
In some cases it may be desirable to have but one inlet passage to the bucket
and but one frusto-conical semi-tubular discharge passage as for instance when it
is desired to place the bucket in close proximity to the end of the drum, in
which case the small end of the flaring discharge passage. would be closed and
the adjustable plunger would have but one inclined inner face all of which may
be done without departing from the principles of my invention.
It will be observed that I use no valves or gates to close the passages through
which the fertilizer is discharged but on the contrary a free passage from the
interior of the drum to the exterior thereof is always open while at the same time
by virtue of the peculiar nature of the material to be distributed and the form of
the passages from the interior to its exterior, no discharge of the fertilizer will
take place so long as the drum is not revolved but when the drum is connected to
the wheel so as to revolve therewith as the machine is moved along the ground the
fertilizer will be discharged from each discharge orifice during about one half of
each revolution and with such near approach to an even and regular discharge that
with three of these measuring receivers and discharging devices in each circum-
ferential row the fertilizer will be evenly distributed in a continuous row along the
ground for each discharge.
It will be seen by reference to Figures 3 and 7 that the two frusto-conical sefni-
tubular passages a and a¹ are so arranged relative to each other that one side of
each is parallel to the axis of the drum and that said sides are in line with each
other while all other parts of the inner surface of said passages are inclined from
their junction to their larger or discharge ends to a constantly increasing angle to
the axis of the drum from the straight or parallel side t around to the opposite
side at t¹.
By making the drums in two sections operated independently of each other, one
may be readily revolved while the other remains stationary which is of advantage,
as when only a narrow strip of land remains to be covered by the fertilizer which
one drum will readily cover, and again it is of advantage in turning corners
with both drums in gear the drum moving over the most ground will make more
revolutions and consequently distribute more material than the other drum which
is making less revolutions.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:-
First. In combination with a hollow revoluble fertilizer holding drum, a device
for receiving measuring and discharging the fertilizer, consisting of a measuring
receptacle set in an opening in the periphery of said drum and projecting inwardly
therefrom and provided with inlet openings in opposite sides thereof contiguous
to the inner surface of the peripheral casing of said drum and with a ledge
projecting inward from said casing a distance equal to about two thirds of the
radial depth of the measuring receptacle, and two discharge passages upon the
exterior of said drum in the form of two frusto-conical semi-tubes with their
smaller ends abutting each other and their inner sides communicating with the
interior of the measuring receptacle.
Second. In combination with a revoluble hollow fertilizer holding drum the
bucket E having one end closed and inclined to the face of the drum to which it
is secured, and the other end open and having the two side openings i, i, the
adjustable plunger F, the ledge G, and the frusto conical semi-tubular passages a
and a¹, all constructed arranged and adapted to operate substantially as and for
the purposes described.

and a¹ and the concentrating ledges H, H secured to the inner surface of the drum
substantially as described.
Fourth. The combination in a fertilizer distributor of a hollow revoluble fertilizer
holding drum, a bucket or receiver partially divided near the middle of its length
by an inwardly projecting ledge or partition into two compartments, an inlet
orifice opening into said bucket or receiver at one side of said partition and
contiguous to the inner surface of the casing of said drum, a passage leading from
said receiver through said casing to the exterior thereof upon the other side of said
partition, and a frusto-conical semi-tubular discharge passage upon the exterior
of said drum and covering said passage from the receiver through the casing of
the drum.
Fifth. In combination with a hollow revoluble fertilizer holding drum, a bucket
or receiver within said drum constructed to receive and measure a quantity of the
material to be discharged and an opening through the peripheral casing of said
druin communicating with the interior of said bucket or receiver, a covering for
the discharge opening through the casing of said drum in the form of a frusto-
conical semi-tube arranged with one of its sides parallel to the axis of revolution
of said drum.
Sixth. A hollow revoluble fertilizer holding drum provided with a series of
tortuous and valveless passages leading from the interior to the exterior thereof
with their discharge openings in planes at right angles to the axis of said drum in
combination with a series of inclined ledges secured to and projecting inward from
