' COCKLE-SEPARATO R.

SPECIFICATION forming part of Letters Patent No. 331,061, dated November 24, 1885. Application filed September 20, 1883. Serial No. 106,907. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK W. HOWELL, 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 aspecification.

This invention relates to an improvement in that class of grain-separators in which the I separation of the different kinds of grain is sectional elevation of the same.

effected by a rotating cylinder provided on its inner surface with cells or indentations, in which the small grains lodge, while the large grains roll back, and more particularly to such a separator in which the grain to be separated is fed upon the inner surface of the separator simultaneously throughout the length of the cylinder. A machine of this kind is described in Letters Patent of the United States No. 266,258, granted to me October 17,1882, to which reference is here made for a'full description thereof.

The object of this invention is to supply the grain to be separated more directly to the cylinder than heretofore, and to render the feed mechanism more compact and reliable; also to improve the construction of the machine generally; and my invention consists of the improvements in the construction of the machine, which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of five sheets, Figure 1 represents a front elevation, and Fig. 2 a rear elevation, of my improved separator. Fig. 3 is a longitudinal Fig. 4 is a cross-section of the machine, on an enlarged scale. Fig. 5 is a fragmentary cross-section on a still larger scale. Fig. 6 is a horizontal section inline m m, Fig. 4:. Fig. 7 is a horizontal section of the front supporting-wheels, Fig. 8 is a horizontal section of the rear supporting-wheels. Fig.9 is a top plan view of one of the knockers. Fig. 10 is a perspective view of one'of the end shields. Fig. 11 is a perspective view of one of the brackets.

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

A represents the stationaryframe of the machine, and B the separating-cylinder supported in the frame A upon rollers 12 b, so that the cylinder can be rotated about its axis. The cylinder Bis constructed on its inner surface with cells or indentations, whereby the different kinds of grains are separated in a well-known manner, the small grains being received in the cells or indentations and elevated thereby as the cylinder rotates, while the large grains are rejected and roll back. The cylinder B is provided in its side with a longitudinal opening or slot, 0, through which the large grains which are not elevated by the cells are finally discharged from the cylinder.

D represents the feed-hopper, which is arranged lengthwise in the cylinder, near the lowest point of thesa'me; and d is the feed: roller, whereby the escape of the material from the feed-hopper is regulated in connection with afeed slide or gate, d, which is made adjustable with reference to the feed-roller by. rackbars d and gea1'-wheelsd ,meshing therewith.

d represents a shield secured to the inner side of the feed-hopper, and projecting over the feed-slide d, to prevent the grain from entering behind the feed slide and obstructing its movements.

E represents a bucket arranged between the feed-hopper and the lower portion of the cylinder B, for the purpose of receiving the grain which ,is gradually discharged from the feed hopper by the rotation of the feed-roller, and discharging such grain at the proper time upon the lower portion of the cylinder. The bucket E consists of two plates, 6 and c, which rest against each other at or near their lower edges and diverge upwardly to receive the ma terial discharged from the feed-hopper. The plate 6 is pivoted at or near its upper end, as shown at 6 either to the feed -h0pper, as represented in the drawings, orto some other stationary part of the machine. pivoted near its lower edge, as shown at c to the end plate F of the feed-hopper, secured to the stationary frame of the machine. The plates 0 and c are connected by links f fin such manner that when the plate 6 is swung upwardly on its pivots from the position represented in full lines in Fig. 5 to the position represented in dotted lines,the plate 6 is swung on its pivots from the position represented in full lines to the position represented in dotted lines, whereby the lower edges of the plates are separated and the plate 6 placed in an inclined position, which causes the grain contained in the bucket to be discharged into the cylinder. This movement of the plates is effected'by cams or projections g, which are secured to the ends of the cylinder and come" in contact with rollers 9, attached to the plate The plate 6 is.

0. The studs or arbors of the rollers 9 project through curved slots g, formed in end plates or shields k When the cams g have cleared the rollers g, the plates 0 e are returned to their former position by gravity, the period of time during which the plates are separated being sufficient to permit the discharge of the accumulated grain from the bucket. The cams g are so located on the cylinder that the bucket will be opened after the opening 0 has passed by the bucket, so that the grain is discharged from the bucket upon that portion of the cylinder next adjacent to and in rear of the opening a. The'cams g are formed on the inner edges of rings which are secured to the ends of the cylinder B. The rings are provided on their outer sides with V-shaped rims g, which run in the grooves of the supportingrollers b b. The grain may be supplied to the feed-hopper by spouts extending through one orboth of the open ends of the cylinder 'D; but in machines of large capacity I prefer to deliver the grain into a preliminary gradingreel, H, which is arranged longitudinally within the cylinder B above the feed-hopper. The reel H is so clothed that the small grains such as cockle-seeds and small wheat or other grain-pass through the meshes of the reel and fall into the feed-hopper D, while the large wheat or other grain passes through the reel and is discharged from the tail end of the reel into a hopper, 'h, the reel being slightly inclined to-cau'se the grain to move longitudinally through the reel.

h represents the shaft of the reel, which is supported in bearings hP, the latter being attached by adjusting-screws h to hangers h, which are secured to the stationary frame A. By means of the screws h the inclination of the reel can be regulated. The adj usting-screws are moved by screw-nuts k resting upon the lower portions of the hangers h.

' H represents a driving-pulley secured to the shaft h.

t represents a longitudinal roller which bears against the outer side of the reel H, or is arranged in close proximity to the outer surface of the reel, and serves to press inwardly and detach any grains which may have lodged in the meshes ot the reel, thereby keeping the reel clear. The rolleri is supported in bearings i, which are attached to the upper ends of the adjusting-screws h, so that the roller takes part'in the movements of the reel in adjusting the pitch of the latter. The roller 6 is preferably constructed of a metallic shaftor core'covered by a tube of rubber or other elastic or flexible material.

J represents the inclined board, which receives the small grain which has been'elevated by the cells of the cylinder B. This board is preferably composed of an upper and lower portion, the former being made adjustable by gearracks j and pinions j, and provided at its upper edge with a roller, j as described in my above-mentioned Letters Patent. The roller j is supported in-hookrshaped bearingsjfiopen and in such close proximity to the cylinder that the grain discharged from the bucket E will be spread by the plate and distributed in a thin layer over the cylinder, thereby preventing the grain from revolving in a large mass on the ascending side of the cylinder, which would interfere with the proper-separation. The plate k is secured with its ends to the end plates or shields, 10 end of the platekis provided with an upwardly-projecting flange, k, which prevents ing on the plate. 1

Instead of constructing the plate, as shown, it may be constructed of a series of bars.

L represents a screw-conveyer, and l the trough of the same, arranged below the cylinder for the reception of the grain which is discharged through the opening 0. The trough lis provided with an inclined extension, l, extending upwardly under the ascending side of the cylinder, and supported 'on its outer edge by castings Z, which extend around the supporting-roller and form close joints around the same. The extension Z receives the material which escapes through the opening 0 as the cylinder rotates, and conducts such mate.

rial to the trough l.

m represents an outwardly-projecting lip or flange formed along the rear edge of the opening 0, for the purpose of catching any small gra'iu'which may lodge on the roller j and return such grain into the cylinder.

N N are plates cast on the lower horizontal cross pieces, a, of the frame A, and extending both below and above said cross-pieces. The end plates F of the feed-hopper D are secured to the inner sides of the end plates-N by bolts n. The plates N are provided with openings closed by caps n n,which are secured to the outer sides of the plates N, and in which the feed-roller d is journaled. I

n represents the driving-pulley, mounted on the shaft of the feed-roller d. The latter exten'dsxthrough the end plate F next the driving-pulley n, so that upon detaching the cap a between the pulley n and the plate F the feed-roller can be drawn out of the feedhopper through the openings in the plates F and N. After the feed-roller has been withdrawn and the end platesFhave been detached from the plates N, the feed-hopper can-be lifted out from between. the plates N. The latter are provided with'openings arranged opposite the. ends of the conveyor K, and made The upper 0-: the grain elevated by the cylinder from fallthe shaft of the conveyer K near the cap 0.

0 represents a spout formed on the cap 0 for the discharge of the grain from the conveyertrough 7c. The ends of the conveyer-trough 7c are secured to flanges 10 east on the inner sides of the shields 75, arranged in the same vertical planes with the end plates F of the feed-hopper. Bolts It extend through the caps o 0, shields and intothe flanges It", so that upon removing these bolts the caps, the shields, and the conveyer-trough 76 can be removed.

The shields k extend upwardly at both ends,

of the cylinder,along the lower portion of its ascending side,for a sufficient distance to prevent the grain contained in the cylinder from escaping over the ends thereof. The lower portions of the shields k and the end plates F of the feed-hopper are arranged at ashort distance from the innersides of the plates N, to leave spaces through which the rings 9 and earns g move.

Upon-detaching the cap 0 next the drivingpulley o from the plate N the conveyer can be removed, and upon detaching the shield from the plates N the trough and connecting parts can be removed.

p p are openings formed in the lower depending portions of the plates N,opposite the screw-conveyer L, and P P are caps closing these openings and secured to the outer sides of the plates N.

p is the driving-pulley secured to the shaft of the conveyer L on the outer side of the cap P, and 10 represents a discharge-spout formed with the cap P. The trough lof the conveyer L is secured to the inner sides of the plates N. Upon detaching the cap P from the plate N the conveyer L canbe withdrawn through the opening 1). The conveyer-troughl is provided at its ends with flanges P, which are secured to the inner sides of the plates N by the same bolts,'Z ,which secure the caps P P to the plates N, so that upon detaching the caps the conveyer-trough is also detached from said plates. 7

q is aspout which connects the hopper h with the discharge-spout 19 so that the large grain discharged from the reel is united with the large grain escaping from the conveyer L.

The rollers b at the head of the machine are secured to shafts 1", which are supported in bearings r, formed on the frame A.

r are driving-pulleys mounted on the shafts r in the same vertical plane with the pulleys c 0 12 The rollers 12 at the tail end of the machine are mounted loosely on studs or arbors r secured to the frame, so that these rollers can adjust themselves on their arbors lengthwise, when the two rings at the ends of the cylinder B are not strictly parallel with each other.

B represents an endless drivechain, running around the pulleys H, 0 01. W, and 10 as clearly shown in Fig. 1, said pulleys being con structed in the form of sprocket-wheels to engage with the drive-chain.

When the machine is not provided with a reel, H, the drive-chain is placed over the upper side of the pulleys 0 c and the flight of the conveyer K and the arrangement of feedslide in the feed-hopper are reversed to correspond with the reversed direction in which the conveyer K and the feed-roller d are rotated in this case.

The frame is composed of end frames, A, and longitudinal connecting pieces A A The latter are constructed of angle-irons, and the upper connecting-pieces, A are secured to the end frames by brackets S. The upper sides of the brackets are fitted in the angles of the connecting-pieces A and secured to thelatter by bolts s, and the ends of the brackets are fitted against the inner sides of the end frames, A, and secured to the latter by bolts 8. Upon removing the bolts 8 the connecting-pieces A and the brackets S secured thereto canbe detached from the end frames,when the cylinder B can be lifted out from between the end frames. The lower connecting-pieces, A are secured at their ends to angular castings S,which are secured to the inner sides of the end frames, A.

T represents knockers mountedloosely on a horizontal shaft or 'rod, t, arranged lengthwise over the cylinder and provided with depending arms t, which are operated by cams or inclines tisecured to the cylinder. The depending arms t are made separate from the knockers and connected therewith by interlocking teeth tfiformed on the contiguous faces of the hubs of the knocker Tand arm t, as represented in Fig. 9, so that the position of the depending arm with reference to the knocker can be changed by disengaging the arm from the knocker and turning said parts with reference to each other, thereby changing the stroke of the knocker accordingly. The knockersare provided with springs t. The knocker is preferably faced with rubber or other elastic material. The springs I? raise the knockers from the cylinder after the blow has been struck, and prevent the knockers from dragging on the cylinder.

The grain to be separated is fedinto the reel H, which effects a separation of the large grain from the smallgrain, the latter, consisting of cockle-seeds, broken wheat, and small wheat, passing through the meshes or perforations of the reel into the feed-hopper D,while the large grain escapes over the tail of the reel into the hopper h. The small grain is delivered from the feed-hopper by the feed-roller into the bucket E, in which the grain accumulates until the bucket is opened by the cams g. This takes place as soon as the opening 0 end of the bucket. The grain contained in the bucket is thereby discharged upon that portion of the cylinder which follows inwardly after the opening. 0. The grain resting upon the inner surface of the cylinder is carried by the rotation of the latter under the plate k, which levels and spreads the grain. The cockle and other small seeds and grains lodge in the cells of the cylinder, and the large grain rolls back. The cockle and small grain are elevated by the rotation of the cylinder and deposited upon the inclined board J, from which it passes into the conveyertrough k,whence it is discharged by the conveyer K through the spout 0 The large grain remains in the cylinder until the opening 0 reaches the lowest point of the cylinder, when the large grain is discharged through the opening 0 into the conveyer-trough Z.

It will be seen that the grain to be separated is delivered more directly into the cylinder than in machines having the feed-hopper on the outside of the cylinder, and that no grain can pass from the feed-hopper to the passages through which the separated grain is removed without having first been subjected to the separating action of the cylinder. Furthermore, the grain is delivered upon the inner cylinder surface with very little movement, so that the entireinner surface of the cylinder is rendered available for the separating operation, while i in machines having the feed-hopper on the outside of the cylinder the grain enters with considerable velocity and passes over a portion of the inner cylinder-surface at too great a speed to permit of the proper separation.

The parts of the machine are so constructed that they can be readily put together in setting up the machine and easily separated when required for making repairs.
