COCKLE-S EPARATOR.

' :EEPhC'IPKIA'JTION forming part of Letters Patent No.346,815, dated August 3, 1886. Application filed February 9, 1886. Serial No.191,319. (No model.)

To all whom it may concern:

Be it .known that I, FREDERICK W. How; ELL, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Cockle-Separators, of which the following is a specification.

This invention relates to an improvement in that class of cockle-separators which consist IO 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 improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of four sheets, Figure l is a longitudinal sectional elevation ofa Cockle-separator provided with myimprovements. Figs. 2and 3 are elevations, respectively, of the feed and discharge ends of the machine. Fig. 4c is a cross-section of the machine on an enlarged scale. Fig. 5

0 is a sectional elevation of the mechanism by which the feed-valve is actuated on an enlarged scale. Fig. 6 is a longitudinal section of one end of the drum and connecting parts. Fig. 7 is a longitudinal section of one end of the feed-hopper. Fig. 8 is a vertical section in linear, Fig. 7. Fig. 9 is a vertical section of one end of the adjustable catch-board. Fig. 10 is an elevation of the lower portion of the main frame. Fig. 11 is a top plan view of one of the roller-guards.

Like letters of reference refer to like parts in the several figures.

The stationary frame of the machine con-. sists of end frames, A A, and longitudinal 4'5 connecting-pieces A firmly secured together and stiffened by brackets a.

13 represents the separati ng-d rum, provided on its inner surface with suitable cells or indentations.

B and B represent rollers supporting the from the reel.

drum B and journaled, respectively, in the end frames, A A, the drum being provided with end rings, b b, which run in the grooves of the supporting-rollers. The shafts of the rollers B at the head of the machine are provided 5 with chain-wheels B, for driving these rollers.

0 represents a separating-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.

0 represents the feed-spout through which the grain enters the reel, and 0 the dischargespout through which the large grain escapes The reel is clothed with wirecloth 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, bymeans of its feed-spout c and an adjustingscrew, 0", and in the end frame, A, by means of an adjustable hanger, c, as represented in Fig. 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 pivoted to bearings d d, secured adjustably to the feed-spout c and hanger 0 so that the brush can be adjusted from time to time to bear firmly against the reel and drum, as may be necessary in consequence of the wear of the brush. The brush-stock is provided on one side of its axis with a weight, (Z 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 Fig. 4:. 0

E represents the feed hopper, arranged lengthwise in the drum B, underneath the reel 0, so as to receive the material which passes through the meshes thereof. This hopper is composed of end plates, 0, and side plates, 6. 5 The side plates, 6, are provided at both ends with flanges e", which overlap the outer sides of the end plates, 6, and which carry handles 0. The end plates, 6, are provided at their inner sides with flanges 0', against which the side rco plates rest. The end plates,e, are secured to the end frames, A A, by horizontal bolts e ,'and the end plates are further supported on the frames by doors e, which are fitted in openings in the 5 frames and to which the end plates, 6, are secured by bolts e. The end plates, 6, are made vertically adjustable on the frames A A by set-screws e so that the lower edges of the curved extensions of the end plates, 6, can be closely adjusted to the inner surfaces of the end rings, b b, of the drum B. The side plates, 6, of the hopper are secured to the end plates, 0, by hooksf, formed on the flanges e of the side plates and engaging over lugs f, l formed on the end plates. Theside plates, 6, are made vertically adjustable by set-screws f, which pass through the hooks f and bear upon the lugs f, as represented in Figs. 3, 4, 5, and 8, whereby the lower edges of the side plates, 6, can be nicely adjusted to the valve E, 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 lugsf by set-screwsj. The side plates, 6, are supported near their lower ends by lugs f, formed on the inner sides of the lower portions of the end plates, 6. Upon releasing the screws f 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 journaled at each end in the end plates, e, so that by placing the valve in the position represented in Fig. 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 Fig. 5. The valve is preferably constructed of angle-iron to render it stifi, and the angle-iron is secured to angular heads 9, which carry the journals 9 g of the valve. The. journal 9. is provided with an arm, 9 which projects downwardly, as represented in Figs. 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 g, 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 ascendingincline, h, which opens the valve, a concentric portion, h, which holds the valve open, and a descending incline, h, which perinits the valve to close without a jar under the influence of weight k, 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 hop per E.

The drum B is provided with a longitudinal opening, J, through which the material is discharged which is not elevated by the indentations of the drum. The cam G is so arranged on thedrum that the valve F is opened immediately after the opening Jhas 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 thismeans the grain is delivered by the automatic valve directly upon the inner surface of the drum, whereby the construction of the ma chine 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 conveyer-trough, which receives the material from the catchboard. 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 repre sented in Figs. 2, 3, 4, and 6, so as to extend upwardly from the lower portions of the hopperplates 6 beyond the upper edge of the catch-board K. Thelatter is pivoted near its lower edge to both carriers M, as shown at m, and is attached to said carriers near its upper edge by screws m, as represented in Figs. 4 and 9, by which the upper edge of the catchboard can be adjusted toward and from the inner surface of the drum. The carriersM are provided withoutwardly-projecting flanges m, which rest upon the curved upper surfaces of the shields N, so thatby moving the carriers upwardly or downwardly the catchboard 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 n, formed on the upper sides of the carriers. The wheels n are secured to a shaft, n, which is journaled in bearings secured to the shields N, and the shaft 'is provided with a hand-wheel, n", by which it isturned. The catch-board is held in position, after it is adjusted, by clamping the shaft n in its divided bearings.

l is an inclined plate extending from the conveyer-trough L upwardly underneath the lower portion of the catch-board.

l is the conveyer-screw, arranged in the trough L, and Z is a chain-wheel secured to the front end of the shaft of the conveyerscrew Z.

0 represents the conveyer-trough, arranged below the drum B and receiving the large grain which escapes from the diseharge-open- 1 25 ing J of the drum.

0 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 A. The front end of the trough O is closed by a cap, P, which is adjnstably supported by ascrew, 12, passing through a lug, p, on the end frame, A, as represented in Fig. 1, so that this end of the IIO trough can be raised and lowered. The cap P is provided with a bearing, p, in which the shaft q of the conveyer-sorew Q, is journaled. The rear end of the trough O is openaud secured to a discharge nozzle or spout, R, by means ofa flange, 1", which is secured to the trough. The spout R is provided with a journal, 1', in which the rear end of the shaft q is journaled. The spout R is secured to the under side of the rear frame,A, by bolts 1' as represented in Fig. 3, and the frame A is provided. on its under side with a recess, 1*, in which the spout R is seated, as representedin Fig. 10, and which permits the rear end of the conveyer to be lowered away from the frame upon removing the bolts 1-. The dischargespout c of the reel 0 opens with its lower end into the discharge-spout It, so that the large wheat coming from the reel and the large wheat discharged from the drum are discharged together from the machine through the spout R.

The discharge-spout c is provided withv a door, 1", which can be turned on its pivots, as represented by dotted lines in Fig. 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, in Figs. 4 and 11, represents guards secured to the upper side of the catclrboard O on the inner side of the rollers B B to prevent the grain falling on the catch-board from passing through the openings in the catchboard in which the rollers B B are arranged. Each guard S consists of an upright flange, s, secured to the catch-board O on an upright flange s, secured to the end of the conveyertrough O, and bearing against the lower end ofthe flanges, as representedin Fig. 11. Upon detaching the catch-board 0 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 B B or the conveyer-trough O. Y

t, in Figs. 1 and 2, represents an endless chain, which runs around wheels T T, and whereby the reel is driven from the lower conveyer'shaft, q.

it represents an endless chain, which runs around a chain-wheel, e, on the conveyer-shaft q, and around the wheels B" and Z whereby the driving-rollers B and the conveyor-screw Z are driven from the lower conveyer-shaft, q. The proper tension of the drive-chains tand a is maintained by adjusting the conveyertrough O and the reel 0.

The grain to be separated passes first into the reel 0, by which the large wheat is separated from the small wheat, cockle, and other fine impurities. The large wheat escapes through the spout 0, 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 eonveyer-trough O.
