ALFRED W. WEYBURN, OF MINNEAPOLIS, MINNESOTA.
IMPROVEMENT IN COFFEE-ROASTERS.
Specification forming part of Letters Patent No. 136,292, dated February 25, 1873.
To all whom it may concern:
Be it known that I, ALFRED W. WEYBURN, of Minneapolis, county of Hennepin and State of Minnesota, have invented a new and useful Improvement in Coffee-Roasters, of which the following is a clear, full, and exact description, reference being had to the accompanying drawing making a part of this specilication, in which- Figure I is a top view of my improved roaster. Fig. II is a section on the line at 00.
My invention has reference to that class of coffee-masters which, being cylindrical in shape, revolve on bearings; and my improvement consists in so constructing the ordinary stove-plate as to allow the cylinder to revolve immediately over and near the fire, while the stove-plate itself remains in position.
To enable others skilled in the art to use and make my invention, I will proceed to describe the exact manner in which I have carried it out.
In the drawing, A is an ordinary stove-plate, but castwith the central opening A, as shown in Fig. II. At each end of the central opening is cast a bearing, D, on which revolves the axle F of the revolving cylinder B, which cylinder is made to fit snugly in the opening A, in which it is caused to revolve during the process of roasting by means of the crank G, or by any other suitable means. The hollow cylinder B, which may be made of sheet-iron, and in which the coffee is placed to be roasted, has an opening, H, with a sliding door, 11,
sliding in the grooves in m, and shown as
