COCKLE-SEPARATOR,

SPECIFICATION forming part of Letters Patent No. 228,310, dated June 1,

Application filed November 24, 1879.

To all whom it may concern Be it known that I, DANIEL BRUBAKER, of Fulton, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Gockleseparators; and 1 do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to animprovement in machines for separating cockle, garlic, wild pease, and all other small seeds which grow among wheat from the same; and it consists in the construction, combination, and arrangement of parts, as will be hereinafter more fully set forth.

In the annexed drawings, which fully illustrate my invention, Figure 1 is a plan view. Fig. 2 is a front elevation. Fig. 3 is a central vertical section on line 00 a, Fig. 1, with metal jacket I removed 5 and Fig. I is a transverse vertical section on line y y, Fig. 1.

Like letters of reference indicate like parts.

A is the frame, of any desired construction. B is the perforated cylinder, of any desired diameter or length, having thirty-six to fifty perforations to the square inch. These perforations are of such size as to prevent the escape of the grain or cockle, but at the same time to allow it to be held in them. 0 are the revolving brushes, which may be made of wire or anyother suitable material. D is the friction-roller, covered with rubber, leather, or

other equivalent substance, for forcing the cockle back into the cylinder. E is the conveyer for carrying off all seeds, cockle, or garlic that pass through the perforations. F is the suction-fan for drawing a current of air through the perforated cylinder. G is an aircompartment.

able air-slides. I is a metal jacket, adjustable on perforated cylinder B, and used on or taken off the same to suit different kinds of grain. When this metal jacket is placed on the perforated cylinder the cams are removed from said cylinder and placed on the outside of said jacket, which makes it fit close to the cylin- H are regulating and adjustder and converts the perforations into cocklepockets. 1 represents the tappet-cams, which may be secured to the perforated cylinder or to the jacketI, and which operate the spring-tapper. J are metal rollers,on which and against which the perforated cylinder B rests and revolves. Kare adjustable bridge-trees,to close or open the brushes or to use them close to the perforated cylinder. L is the adjustable feed-spout. M .is the cocklespout. N are spring-standards supporting the roller D. O are adjusting-screws for the roller D. P are adj Listing-screws for the bridge-trees. Q are gear-wheels. R is a cog-wheel, with crank or other mechanism attached, for imparting motion to the wheels Q, to revolve the cylinderbrushes andconveyer. S is a band-wheel for imparting motion to the suction-fan. T is a spring-tapper, adapted to be operated so as to give the cylinder a hard or light blow. a are lighter screws at the bottom of the machine, for regulating the pitch of the same. b is the discharge-opening in the conveyer-chamber. c are inclined grooves in the upper and lower side bars of the frame. (Z are tongues on the bridge-trees, fittin g into the grooves c. c is an adjusting-screw to raise and lower the feed-spout L, to gage the amount of wheat the machine will carry.

When the machine is in use it is inclosed within a suitable casin g rendered sufficiently air-tight to admit of the operation of the parts, as described.

The operation of the machine is as follows: When the machineis in motion the wheat passes through the adjustable delivery-spout L to the perforated cylinder B, and as the cylinder revolves the wheat drops flat on a smooth surface, and is distributed flat until it comes to the perforations. In the rotation of the cylinder the wheat-grains, being long, fall out of v the pockets, while the seeds and cockle are carried clear up and delivered into the trough M by the brushes, and the wheat slides on the incline to the tail end of machine. The cockle and garlic deposited in the perforations are carried up as the cylinder revolves, an d are caught by the revolving brushes and discharged into the discharge-spout M, the outside frictionroller pressing back any cockle or garlic hanging in the perforations, which is instantly caught by the revolving brushes and discharged to the spout M.

The spring-tapper T, when the cylinder is revolved, passes over the cams I, arranged on thejacket or perforated cylinder, giving a hard or light tap on the same, which causes the cockle, garlic, or other small seed to drop out of the perforations into the cylinder, leaving the brushes to remove it to the discharge-spout and discharge it. By this operation of the tap per on the cylinder, the two revolving brushes, and outside roller, the perforated cylinder never becomes clogged with cockle, garlic, or any other seeds.

The brushes 0 as arranged to revolve perform a triple function, viz: They clean the pockets with opposite motions, they clear one another, and they jointly feed the cockle to the spout M.

The suction-fan is also used to separate broken grain from the cockle, and the cockleseeds and broken grain that are too large to go through the perforations are separated by the revolving brushes and air-currents.

Automatic cams are used on the outside of thecylinder-case to clear the perforations when the jacketis used on the case. The jacket is easily removed, and all small cockle-seeds, &c., pass through the perforations.

The perforations may be made larger or smaller in sections, to suit the different-sized grain.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination of the interior brushes, 0, revolving with a feed motion toward each other, with the perforated cylinder for clearing the cockle holes or cells, substantially as specified.

2. The interior brushes, 0, revolving with a feed motion toward each other, in combination with the perforated cylinder B and the cocklespout M, for receiving the material brushed out from the perforations, to prevent its return to the contained grain, substantially as described.

3. The combination of the bridge-tree supporting the brushes with the inclined grooves c and adjusting-screws P, whereby one or both of the brushes may be thrown into or out of operation, substantially as shown.

4. The removable jacket I, in combination with the perforated cylinder B, the interior brushes, 0, revolving with a feed motion toward each other, the cams I, and spring-tappet T, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.

DANIEL BRUBAKER.
