VUNITED STATES PATENT OFFICE.

GEORGE B. HAMILTON, OF I/VASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO HIMSELF AND ANDREW NOERR, OF SAME PLACE.

IMPROVED ORE-WASHER.

Specification forming part of Letters Patent No. 53,221, dated MarchlS, 1866.

To all 'whom it may concern: Be it known that I, GEORGE B. HAMILTON of Washington, in the county of Washington and District of Columbia, have invented a new and useful Improvement in Ore-Washers and I do'hereby declare that the followingis a-full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in a peculiar construction and arrangement of machine for washing ore.

In the accompanying drawings, Figure l is a vertical section near the center ofmy machine. Fig. 2 is an end View of the machine.

Upon any suitable frame, A, Fig. 1, I arrange a semicircular trough `or cistern, B, with one end higher than theother. In this cistern is placed a hollow cylinder or washer, C, provided with ribs or ylifters D, set obliquely, as indicated in dotted lines, Fig. 2, at D. The cistern or trough Bis furnished with a constant stream or supply of water, and" the cylinder or agitator C is set in revolution by the crank E, orother suitable means. The ore is shoveled into Ythe cylinder C from the platform F. As the cylinder revolves water is dipped up by the trunks G and iows into cylinder at holes G', Fig. l. As soon as the water rises to the red line, Fig. l, there is a constant overflow at theleft-hand end of the cylinder, as indicated by the arrow, while a continuous supply of water is dipped'up by the trunks G. As the water thus liows from the right to the left, washing away the dirt, the ore slowly passes to the right on account of the oblique position of the cylinder, and at the same time the lifters D seize the ore and carry it up the -side of the revolving cylinder to fall back again into the Water. Thus the ore is thoroughly agitated and washed vand finally collected at the right-hand or lower end of the cylinder, where a portionYV of the same is taken up at each revolution of the cylinder by the discharger O and carried into the oblique passage I, froin which it falls upon the sieve K.

A portion of water being carried forward with each discharge of ore washes the tiner particles through the sieve to be collected and set-` tle in a reservoir below.

I propose to employ several sieves, if necesesa-ry, the same being shaken by trips L striking` the lever M in the usual manner.

I do not confine myself1 to the proportions above set forth; but I propose to vary the dimensions and details of construction, using substantially the same machine.

Havin g thus fully described my invention, Y what I claim, and desire to secure by Letters- G'Eo. B. HAMILTON.
