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
particularly described and ascertained in and by the following statement:-
This invention relates to that class of cockle-separators, which consist of a
revolving drum provided on its inner side with pockets, cells, or indentations in
which the cockle and other small impurities embed themselves, and by which the
same are elevated and delivered to a catch-board, while the wheat and larger
grains roll back and are separately discharged.
The object of the present invention is to improve the construction and operation
of machines of this kind; and my invention consists, to that end, of the improve-
ments hereinafter set forth.
In the accompanying drawing,
Figure 1 is a longitudinal sectional elevation of a cockle-separator provided with

page_text: The stationary frame of the machine consists of end frames A, A¹, and longi-
tudinal connecting-pieces A, firmly secured together and stiffened by brackets a.
B represents the separating-drum, provided on its inner surface with suitable
cells or indentations.
B1 and B2 represent rollers supporting the drum B and journalled, respectively
in the end frames A, A¹, the drum being provided with end rings b, 61, which run
in the grooves of the supporting rollers. The shafts of the rollers B₁ at the head
of the machine are provided with chain-wheels B³, for driving these rollers.
C represents a reel arranged lengthwise in the drum B, for the purpose of
separating from the material the large grain which should not go to the separating
drum, and for distributing the material lengthwise in the drum.
o represents the feed-spout through which the grain enters the reel, and c¹ the
discharge-spout through which the large grain escapes from the reel. The reel is
clothed with wire-cloth or perforated metal of the proper mesh to effect a separation
of the large grain, which tails off from the small and broken grain, cockle and
other small impurities which pass through the meshes of the reel. The reel is
adjustably supported in the end frame A by means of its feed-spout c and an
adjusting-screw, c³ and in the end frame A¹ by means of an adjustable hanger c³,
as represented in Figure 1.
D represents a duplex brush, which bears against the inner side of the separating-
drum and the outer side of the reel, and which is pivotted to bearings d, d¹ secured
adjustably to the feed-spout c and hanger c³, so that the brush can be adjusted from
time to time to bear firmly against the reel and drum, as may be necessary in con-
sequence of the wear of the brush. The brush-stock is provided on one side of its
axis with a weight d, which counteracts the tendency of the reel to turn the brush
on its pivots away from the reel and drum,.and which keeps the brush in contact
with these parts, as represented in Figure 4.
E represents the feed, hopper, arranged lengthwise in the drum B, underneath
the reel C so as to receive the material which passes through the meshes thereof.
This hopper is composed of end plates e and side plates e¹. The side plates e¹ are
provided at both ends with flanges e which overlap the outer sides of the end
plates e and which carry handles e³. The end plates e are provided at their inner
sides with flanges e, against which the side plates rest. The end plates e are
secured to the end frames A, A¹ by horizontal bolts e, and the end plates are
further supported on the frames by doors e which are fitted in openings in the
frames and to which the end plates e are secured by bolts e7. The end plates e are
made vertically adjustable on the frames A A¹ by set-screws e³, so that the lower
edges of the curved extensions e³ of the end plates e can be closely adjusted to the
inner surfaces of the end rings b, b¹ of the drum B. The side plates e¹ of the
hopper are secured to the end plates e by hooks f, formed on the flanges es of
the side plates and engaging over lugs f¹ formed on the end plates. The side
plates el are made vertically adjustable by set-screws f³, which pass through the
hooks fand bear upon the lugs f¹, as represented in Figures 3, 4, 5 and 8, whereby
the lower edges of the side plates e¹ can be nicely adjusted to the valve F, which
opens and closes the discharge-opening of the hopper E. After the side plates
have been so adjusted they are clamped in position on the lugs f¹ by set-screws f³.
The side plates e¹ are supported near their lower ends by lugs f* formed on the
inner sides of the lower portions of the end plates e. Upon releasing the screws f³
the side plates can be removed through either end of the machine.
The valve F is arranged horizontally underneath the discharge-opening of the
hopper E, and is journalled at each end in the end-plates e, so that by placing the
valve in the position represented in Figure 4 the discharge-opening of the hopper
is closed, while by giving the valve a partial turn its upper face is inclined, thereby
opening the mouth of the hopper, as represented by dotted lines in Figure 5. The
valve is preferably constructed of angle-iron to render it stiff, and the angle iron
is secured to angular heads g, which carry the journals g', g³ of the valve. The

page_text: journal g¹ is provided with an arm g³, which projects downwardly, as represented
in Figures 1 and 5, and which is operated by a cam G secured to one end of the
drum. When the drum is very long, each end of the valve may be provided with
an actuating arm and cam. The cam G is secured to the outer side of the end
ring b of the drum by bolts which are preferably removable, so that when the
indentations of the drum have become worn at their lower edges, compared with
the direction in which the indentations ascend on the working side of the drum,
the drum can be reversed, and the cam G can be secured to the opposite end of the
drum. The cam G is provided with an ascending incline h, which opens the valve,
a concentric portion h which holds the valve open, and a descending incline h
which permits the valve to close without a jar under the influence of weight h³
which is attached to the valve laterally of the axis thereof. The weight also
serves to hold the valve closed against the pressure of the grain in the hopper E.
The drum B is provided with a longitudinal opening J through which the
material which is not elevated by the indentations of the drum is discharged.
The cam G is so arranged on the drum that the valve F is opened immediately
after the opening J has passed the discharge-opening of the hopper E so that the
grain to be separated is delivered upon the inner surface of the drum directly in
rear of the opening J. It will be seen that by this means the grain is delivered by
the automatic valve directly upon the inner surface of the drum, whereby the
construction of the machine is greatly simplified and its operation rendered more
reliable.
K represents the inclined catch-board, arranged within the drum B on the
ascending side thereof, and L is the conveyor trough which receives the material
from the catch-board. The latter is supported at both ends by carriers M, which
rest upon shields or plates N curved concentric with the drum and secured to the
end frames A, A', as represented in Figures 2, 3, 4 and 6, so as to extend
upwardly from the lower portions of the hopper plates e beyond the upper edge of
the catch-board K. The latter is pivotted near its lower edge to both carriers M,
as shown at m, and is attached to said carriers near its upper edge by screws m³,
as represented in Figures 4 and 9, by which the upper edge of the catch-board can
be adjusted toward and from the inner surface of the drum. The carriers M are
provided with outwardly-projecting flanges m³ which rest upon the curved upper
surfaces of the shields N, so that by moving the carriers upwardly or downwardly
the catch-board is raised or lowered in the drum without changing. its distance
from the drum. The carriers M are moved on the shields N by gear wheels n,
which engage with gear-segments n¹ formed on the upper sides of the carriers.
The wheels n are secured to a shaft, n³ which is journalled in bearings secured to
the shields N, and the shaft is provided with a hand-wheel n³ by which it is
turned. The catch-board is held in position, after it is adjusted, by clamping the
shaft n² in its divided bearings.
is an inclined plate extending from the conveyor-trough L upwardly underneath
the lower portion of the catch-board.
is the conveyer screw, arranged in the trough L, and is a chain-wheel secured
to the front end of the shaft of the conveyer screw D.
O represents the conveyer-trough, arranged below the drum B and receiving the
large grain which escapes from the discharge opening J of the drum.
01 is an inclined catch-board, which extends upwardly from one side of the
trough O to the side of the main frame, where it is supported by one of the
horizontal pieces A². The front end of the trough O is closed by a cap P, which is
adjustably supported by a screw p, passing through a lug p³ on the end frame A,
as represented in Figure 1, so that this end of the trough can be raised and
lowered. The cap P is provided with a bearing p' in which the shaft q of the
conveyer-screw Q is journalled. The rear end of the trough O is open and secured
to a discharge nozzle or spout R, by means of a flanger which is secured to the
trough. The spout R is provided with a journal in which the rear end of the

page_text: shaft q is journalled. The spout R is secured to the under side of the rear frame A
by bolts, as represented in Figure 3; and the frame A is provided on its under
side with a recess in which the spout R is seated, as represented in Figure 10,
and which permits the rear end of the conveyer to be lowered away from the
frame upon removing the bolts 2. The discharge-spout c¹ of the reel C opens
with its lower end into the discharge-spout R so that the large wheat coming from
the recl and the large wheat discharged from the drum are discharged together
from the machine through the spout R.
The discharge-spout is provided with a door, which can be tained on its
pivots, as represented by dotted lines in Figure 1 for the purpose of delivering
from the spout c', a sample of the material which tails off from the reel. If this
material contains cockle, the rear end of the reel is raised to keep the grain longer
in the reel.
- S. S. Figures 4 and 11 represent guards secured to the upper side of the
catch-board O¹ on the inner side of the rollers B¹ B', to prevent the grain falling
on the catch-board from passing through the openings in the catch-board in which
the rollers B¹ B2 are arranged. Each guard S consists of an upright flange 8
secured to the catch-board 01 on an upright flange s¹ secured to the end of the
conveyer trough O and bearing against the lower end of the flange 8, as represented
in Figure 11. Upon detaching the catch-board O' from the horizontal piece A' of
the main frame the catch-board can be removed, with the flanges 8 attached
thereto, without disturbing the rollers B1 B2 or the conveyer-trough O.
t, Figures 1 and 2, represents an endless chain, which runs around wheels T T¹
and whereby the reel is driven from the lower conveyer-shaft q.
u represents an endless chain which runs around a chain-wheel v on the
conveyer-shaft q, and around the wheels B³ and 1, whereby the driving-rollers B¹
and the conveyer screw are driven from the lower conveyer-shaft q. The proper
tension of the drive-chains t and u is maintained by adjusting the conveyer-trough
O and reel C.
The grain to be separated passes first into the reel C, by which the large wheat,
is separated from the small wheat cockle and other fine impurities. The large
wheat escapes through the spout c¹, while the small grains pass through the
meshes of the reel into the hopper E. The small grain is intermittently discharged
from the hopper upon the drum, which elevates the cockle and other small
impurities while the wheat is rejected and rolls back until it reaches the opening J
in the drum, through which it is discharged into the conveyer-trough O. The
cockle and other small impurities fall upon the catch-board K, and are removed by
the conveyer L, P.
