COCKLE-SEPARATO R.

SPECIFICATION forming part of Letters Patent No. 442,051, dated December 2, 1890.

Application filed July 12, 1887. Serial No. 244,071. (No model.)

To all whom tm/ty concern.-

Be it known that I, FREDERICK W. HOWELL, of the city of Buiicalo, in the county of. Erie and State ot' 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 consists of a revolving drum provided on its inner side with cells or indentations, in which the cookie 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 present invention has reference more particularly to improvements upon the machine described and shown in Letters Patent No. aldgranted to me August 3, 1886,:and has for its object to increase the separating capacity of the machine and to improve the construction of the saine in various respects.

The invention consists of theimprovements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of three sheets, Figure l represents an elevation of the feed end of the machine. Fig. 2 is a vertical longitudinal section of one of the upper corners of the main supporting-frame on an enlarged scale. Fig. represents a fragmentary perspective view of the brush and one of its supporting-hangers separated from each other. Fig. Llisa longitudinal sectional elevation of one end of the reversible brush and its supporting parts. Fig. 5 is a crosssection ot the machine on an enlarged scale. Fig. G is a longitudinal sectional elevation ot' the upper portion of the machine. Fig. 7 is a fragmentary internal elevation of the end plate of the hopper and the shield in which the hopper is supported. Fig. Sis a vertical section in line w x, Fig. 7. Fig. 9 is a side elevation, on an enlarged scale, of the adjustable support in which the driving-rollers of the drum are journaled. Fig. lO represents a sectional elevation of the cockietrough and the plate or shield in which the cockle-trough is supported, the cockle-trough being raised from the shield. Fig. 'll represents a vertical section ot' the discharge end of the cockle-trough in line y y, Fig. 5. on an enlarged scale. t

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

The stationary supporti n g-f rame of the machine is composed of end frames A A and tubular longitudinal connecting bars or pieces A2, which are secured together by brackets or corner-pieces A3. The brackets A3 are secured to the end frames A A by horizontal bolts a a. and to the tubular connecting-pieces A2 by vertical bolts a2 a3. The bracketsAS are each provided at their outer ends with a collar or ring a4, which embraces the tubular connecting pieces and through which the bolt a3 passes, and at their inner ends with a nipple ai", Which its into the end of the tubular connecting-bar and through which the fasteningbolt a2 passes. This construction forms a simple and rigid connection between the end pieces and longitudinal pieces of the supporting-frame. I

B represents the rotating separating-drum provided on its inner surface with cells or indentations B', and B2 B3 represent the rollers supporting the drum, the drum being provided With end rings B4, which run in the grooves of the supporting-rollers. The rollers B2 are arranged on one side of the drum B and are journaled in xed bearings formed in the end frames A A', while the rollers B3 are arranged on the opposite side of the drum and mounted in movable bearings b. Each bea-ring b is arranged in a rectangular t rame the upper and lower sides of the adjustable frame b. By this means the rollers Bs on one side of the drum can be adjusted vert-ically and horizontally, as may be necessary, in order to cause thc rings BL of the drum to IOO the outer reel C.

by a vertically-adjustable bar cl2.

bear uniformly upon the supporting and d riving rollers.

C C represent two separating-reels 'arranged lengthwise in the drum, one within V5 the other, and whereby the larger grain which should not go to the separating-drum is separated from the small grain and seeds. The reels C C are clothed with wire-cloth or per-V forated metal of the proper mesh to separate io the large grain from the small and broken grain, cockie, (be. The inner reel C is clothed with coarse wire-cloth or perforated metal, so that all the grain and seeds, excepting large wheat, pass through the inner reel and upon The latter is provided with a finer clothing, which permits the cockle and small seeds only to pass tl'n'ough, while the medium-sized wheat is carried to the tail end of the outer reel, Where it coininingles with 2o the large wheat which tails off from the rear end of the inner reel, the reels heilig slightly inclined in order to produce this movement of the grain. The reels C C are provided at their front end with a head c, which is con- 2 5 `structed with two concentric flanges to which the clothing of the reels is secured, and which is supported onV the shaft c by means of arms c2 and a hub c3.

c4 represents the feed-spout which enters a 3o central opening in the head c.

ci represents the head arranged at the tail ends` ot the reels and secured to the shaft c by arms c and a hub c7. The head c5 is provided with a central opening, and on its inner 3 5 side with curved elevating ribs or buckets c,

extending from this opening to the outer peripheral iiange cfof the head, to which flange the rear end of the outer reel-clothing is secured. 'lhe rear end of the inner reel is se- 4o cured to a ring c1, which is attached to the 5o and are elevated bythe buckets or ribs e8 and delivered into the discharge-spout c, byv which this kind of grain is removed without passing upon the indented drum. By constructing the machine with two reels in this manner the separating capacity of the inachine and the efficiency of the indented separating-drum are greatly increased.

D represents a reversible brush, which is arranged lengthwise within the drum and 6o adapted to bear against the inner surface of the separatingfdrum or the outer surface of the outer reel C, as may be desired. The

brush D is supported in slotted hangers CZ, depending from the top portion of the end frames A A', and is provided at both ends with screw-threaded shanks fZ, which project through the slots of the hangers CZ and are sethe meshes of the outer reel.

cured therein by thumb-nuts (Z2 applied to said shanks and bearing against the outer sides of the hangers CZ. Upon loosening the thumbwnuts (Z2 the brush can be either reversed, so as to bear against the reel C or the drum B, as desired, or it can be adjusted in the slots of the hangers to take up the wear of the brush. The stock (Z3 of the brush is provided on its outer edges with a longitudinal angle-iron or strip (Z4, which st-iffens the brush and prevents the same from warping, sagging, or twisting.

E represents the feed hopper arranged lengthwise in the drum B below the reels C C and receivingthe material passing through The feed-hopper E is composed of side plates e and end plates c. The end plates e are secured to the end frames A A by horizontal bolts e2, and their V-shaped lower ends rest in correspondin gly-shaped recesses f, formed in plates or shields F. The latter are curved concentric with the drum B and secured to the end frames A A.

G represents the valve which closes the discharge-opening of the hopper E, and which is opened intermittently by a cam H, formed on the drum B, the valve being Weighted so as to remain in a closed position when released by the cam. The valve G is journaled in bearings t, formed lpartly in the shields F and partly in the end pieces c of the hopper, as clearly represented in Figs. 7 and 8. This construction enables the valve to be easily applied and removed upon lifting the end plates of the hopper from the shields. The end plates of the hopper are provided near their lower ends with lugs or projections e3, upon Ywhich the lower ends of the side plates e are supported.

I represents the inclined catch-board arranged within the drum B on the ascending side thereof, and which is made in the form. of a compound curve, whereby the board is stiffened and aclose lit of the saine With the drum B is obtained. The upper part of the catch-board is made convex on its upper side and the lower part of the catch-board is made concave on its upper side, as represented in Fig. V5. ends by carriers K,Which slide upon the shields or plates F, so that the catch-board can be raised or lowered in the drum. The catchboard is pivoted near its lower edge to the carriers K, and is attached to said carriers near its upper edge by screws Z, by which the upper edge of the catchboard can be adj usted The catch-board is supported'at both IOC IIO

is allowed to fall through the spaces between the teeth, thereby preventing the latter from becoming clogged with grain, &c. The gearwheels n1, are mounted on a horizontal shaft fm2, which is journaled in bearings secured to the shields F, and the shaft is provided with a hand-wheel m3, whereby it is turned.

N represents the conveyer-trough, which receives the cockle and other small material from the eatclrboard I, and which is seated in the shields F. The latter are provided with lugs n, upon which the flanges n of the conveyentrough N rest. The trough N is provided in its under side with notches n2, which tit over projections n3 formed on the shields F, and whereby the trough is centered in the recesses of the shields and prevented from turning therein.

o represents an extension or plate formed on the inner side of the cockle-trough and extending upwardly below the lower portion of the catch-board I.

0 representsaguard-plate which is secured with its upper end to the under side of the catch-board, and which extends downwardly below the extension o of the coekle-trough and conceals the same. This guard-plate prevents grain, dust, and other material from entering between the catch-board and the extension o. The guard-plate o is supported by an angle-iron 02, which rests loosely between lugs o3, formed on the inner sides of the shields F.

04 represents stops formed at the lower end of the guard-plate o', and which strike the angle-iron 02, so as to limit the upward movement of the catch-board and prevent the teeth 'nt' from becoming disengaged from the gear-wheels m. The angle-iron o2 also supports the catch-board I and the extension o of the conveyer-trough N and prevents these parts from sagging.

P represents a conveyer-trough arranged below the drum B and receiving the grain which escapes from the longitudinal discharge opening or slot p of the drum.

P represents the conveyer-screw arranged in the .trough P, and p is a sprocket-wheel secured to the shaft of the conveyer I.

Q represents a sprocket-wheel secured to the shaft e of the separating-reels C C', and Q Q2 are sprocket-wh eels secured to the driving-rollers B2 B3 of the drum B.

R represents an endless chain which runs around the wheels Q Q Q2 jp', and whereby the reels C C', rollers B2 B3, and conveyer P are driven.

S represents a spur er sprocket wheel secured to theshaft of the cockle-conveyer and which meshes with the sprocket-wheel Q. By this construction short bends are avoided in the drive-chain, whereby the friction on the chain is reduced. Power is preferably applied to the shaft of the lower conveyerP.

I claim as my inventionl. The combination, with the indented drum B, of the separating-reel C, arranged 4within said drum and provided with elevating-buckets at its tail end, and the reel C', arranged within the reel C and discharging into the tail of the surrounding reel C, substantially as set forth.

2. The combination, with the feed-hopper E and its dischargeyalve G, of the shields F, upon which the hopper :is supported, and valve-bearings g, formed partly in the shield and partly in the feed-hopper, substantially as set forth.

3. The combination, with the drum B, conveycr-trough N, provided with an extension o, and the catch-board I, of a guard plate or shield o', attached to the catch-board and extending below said extension, whereby the material in the drum is prevented from entering between the eonveyer-trough and the catch-board, substantially as set forth.

4. The combination, with the shields F, the conveyer-trou gh N, and the catch-board I, provided with a guard-plate o', of an angle-iron or strip o2, which is supported upon the shields F and upon which the guard-plate rests, substantially as set forth.

lVitness my hand this 7th day of May, 1887.
