To all whom it may concern: I I use a hard and a soft surface together, Be it known that I, WM. M. ARNALL, of because the hard surface presses the cookie Sperryville, in the county of Rappahannock beard into the soft surface, and thus it is carand State of Virginia, have invented certain ried securely away. Where two felt surfaces new and useful Improvementsin Grain-Oleanare used, the cockle sticks alike to both, and ers; and I do hereby declarethat the following when the two surfaces part, being drawn in is a full, clear, and exact description of the two directions, its hold on the cylinders is same, reference being had to the accompanypartially loosened, and the wheat falling ing drawings, and to the letters of reference against it removes a great deal of it from the marked thereon. cylinders, and it is.thus carried down with The nature of my invention consists in conthe wheat. structing and arranging the several parts of I am aware that a series of felt rollers are this machine substantially in the manner used for the purpose of removing the cockle hereinafter specified. from grain but it alniostimpossible,even with In the annexed drawings, Figure l reprea series to remove the cockle, for the reason sents a plan view of the machine.

They may be driven by gearing or otherwise, as may be desirable.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the distributing and equalizing cylinder I with the separating-cylinders D and E, the same being used as and for the purpose specified.

2. The arrangement of the cylinder I and adjusting-spring N, or their equivalents, with the cylinders D and E, and with the brush F, when the same are used substantially as for the purpose specified.
