lIMPROVEMENT IN MACHINES FOR SEPARATING COCKLEl &c, FROM WHEAT.
l Specification forming part of Letters PatentNo. 142,119, dated August 26, 1873 application filed February 4, 1873.
To all whom it may concern:
Be it known that I, GEORGE H. Rromof Geneva, in the county of Kane and State of Illinois, have invented certain Improvements in Machines for Separating Gockle and small Seed from Wheat, 85o., of which the following is a specification:
This invention consists in employing a hollow revolving cylinder perforated with holes large enough to allow the passage of the cockie-berries, said cylinder being surrounded upon its under surface by an endless apron held up closely against the outside thereof' by means of rollers, as will hereinafter more fully appear. The grain is fed into this cylinder at one end and passes out at the other by its own gravity, the cylinder being slightly inclined to insure this result. The metal composing the cylinder is made of such a thick-4 ness that the perforations, when obstructed upon the outside by the apron, form cavities of a depth just sufficient to allow the cockleberries to lie below the inner surface of the cylinder, but so shallow that the berries 'of wheat which may lodge in them endwise will proj ect in part within the cylinder, and, by the action of the body of grain in the revolution,
will be swept back into the cylinder, while the cockle rides upon the apron and is discharged outside by the action of the apron, which is moved continuously by its contact with the revolving. cylinder, being kept taut by the weight of the cylinder resting upon it; and the invention further consists in the method of feeding the cylinder by means of a chamber, into which the grain is led, and into which projects the mouth of the cylinder, which is furnished with a set of inclined internal vanes,
Fig. 2 is a central vertical transverse 'and use my invention, I will proceed to de- `and it is desired that no wheat shall pass over with the cockie. The material of the cylinder 'should' be of a thickness a little greater than one-half the largest diameter of a cockie-seed. B is the endless apron passing around the outer under surface of the cylinder in Contact therewith, and breaking contact on both sides of the cylinder below the horizontal center. This apron at each side ofthe cylinder passes over the rollers C C, and below passes under the roller C', the three rollers being placed in a triangle. The roller C is carried in a bearing which allows it to move vertically, so that its weight will stretch the apron and hold it firmly against the cylinder; and to insure this result I prefer to make this roller G of metal to give it weight. D is a brush roller, so mounted that it revolves by contact with the outer surface of the cylinder. This brush may be made stationary, if desired; but'I prefer, for obvious reasons, that it should rotate, and recommend thatA construction. By means of this brush the perforations are kept clear of grain and debris. E is a chamber, into which the grain to be cleansedis poured. The mouth a of the cylinder enters this chamber, and, by means of the internal screw arrangement of the inclined vanes b b', draws the grainV into the cylinder with a steady feed, which should be so regulated as to keep said cylinder not more thanhalf full. F are the discharge-ports,
with inclined wings to regulate'the amount ot' discharge. G is a conveyer to carry the cockle and screenings out at the end of the machine.
The cockle and any broken b its of grain of a similar size, by the action of the revolving cylinder, finally lodge in theV perforations apron as a door is not deep enough to take in the entire Wheat-berry. The revolution of the cylinder carries up such cockie-berries as may have lodged, and they pass over the roller and fall below to the conveyer.' This peculiar action is clearly shown at Fig. 2 of the drawing. The centrifugal force of the cylinder While revolving tends to cause the discharge of the cockie from the apertures after they are free of the apron, and by the same reason tends to keep them securely in the apertures until free from the apron.
Having thus fully described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is
