NEW YORK, N. Y.

COFFEE-SCOURING MACHINE.

SPECIFICATION forming part of Letters Patent No. 249,943, dated November 22, 1881 Application filed May 25, 1881.

To all whom it may concern Be it known that we, GEORGE W. HUNGER- FORD and GEORGE S. HUNGERFORD, both citizens of-the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Coffee-scouring Machines, of which the following is a specification.

Thisinvention relates to machinery for scouring or cleaning eofiee and other similar materials; and it consists in the hereinafterdescribed bearing, swiveled at its lower end on a horizontal pivot, and constituting a journalbox for one end of the cylinder-shaft, in combination with a sliding bearing connected with an adjusting-screw arranged in supportingguides on the frame of the machine, said sliding bearing constituting also a journal-box for the other end of the cylinder-shaft, all as hereinafter more fully described.

This invention is illustrated in the accompanying drawings, in which Figure l represents a longitudinal central section. Fig. 2 is an end view of the outer cylinder. Figs. 3 and 4 are detail views of the bearings respectively.

Similar letters indicate corresponding parts.

The letter A designates the, inner cylinder, and B the outer cylinder, provided with spurs 5 on their opposed surfaces, for scouring the coffee or other material passing between them, the material being fed to the outer cylinder at one end by the hopper 6, and discharging therefrom atits opposite end through ports 7 ,formed at that point. A portion of the outer cylinder, B, near its delivery end, is made of wirecloth B, or the like, to allow the escape of the dust or other matter removed from the material. The inner cylinder, A, is fixed to a shaft, 0, and the outer cylinder to a shaft, D, both shafts being provided with a pulley, S or 9, for imparting thereto and thence to the cylinders a revolving motion. The shaft D of the outer cylinder is tubular and is placed looselyon the other or inner shaft, 0, and pro- 5 jecting through and beyond the cylinders at both ends, together with the inner shaft.

The letters F G designate the bearin gs for the shafts O D. The bearings of themselves constitute journal-boxes in which the ends of (No model.)

the cylinder-shaft revolve, and said boxes and bearings are independent of each other. The bearing F is swiveled by means of a horizontal pivot, 10, fixed to asuitable part of the machine-frame, while the bearing G is arranged to slide in guides 11 on the frame, the pivot being horizontal, while the guides are vertical. The sliding box or bearing G, moreover, is fitted loosely in the guides 11, so that it has sufficient play therein to admit of its vertical movement.

To the sliding bearing G is connected the lower end of a screw, H, which extends through a cross-piece of the machine-frame, and is provided with a nut, 12, on its upper threaded part, for its adjustment. By adjusting the screw H in an appropriate manner the sliding bearing G can be moved up or down, carrying with itthe adjacent delivery end of the cylinders through the shaft G, the body of-the cylinders swinging on the pivot or swivel joint 10 during such motion. When the sliding bearing G is moved in a lower direction the cylinders are broughtto an inclined plane from the receiving end to the delivery end, the effect of which is to cause the material to travel toward the lower or delivery end by gravity; and inasmuch as the degree of such inclination can be varied, the passage of the material can be hastened or retarded, subjecting it to the action of the cylinders for a shorter or longer period of time.

Heretofore the cylinders of a coffeemill have been arranged within arectangularframe which is pivoted at one end and suspended at the other end within abraeket which has a threaded vertical shank passing through an adjustingscrew; but such structure does not constitute our invention. The casing of a grinding-mill has also been pivoted at one end to a supporting-base and at its other end to a screw-support for adjusting the elevation of the end of the casing; but neither does such structure constitute our invention.

What we claim as new, and desire to secure by Letters Patent, is-- In a machine for scouring cofi'ee, the bearing F, swiveled at its lower end on a horizontal pivot, 10, and constituting a journal-box for one end of the cylinder-shaft, in combinaour hands and seals in the presence of two tion with the sliding bearing Gr, connected subscribing witnesses.

with an adjusting-screw arranged in supporting-guides 11 on the frame of the machine, said GEORGE HUNGERFORD' F" J sliding bearing constituting also a journal-box HUNGERFORD' for the other end of the cylinder-shaft, all sub- \Vitncsses: stantially as shown and described. LEVY COHEN,

In testimony whereof we have hereunto set MICHAEL E. CARLEY.
