ORE-WASH ER.

SPECIFICATION forming part of Letters Patent No. 265,766, dated October 10, 1882.

Application filed September 24, 1881.

To all whom it may concern:

Be it known that I, ALONZO MESIA DE LA GERDA, a citizen of Spain, residing at Madrid, in the'Kingdom ofSpain, have invented a new and useful Improvement in Ore VVashers, (for which I have obtained a patent in Spain, dated May 19, 1879, No. 184,) of which the following is a specification.

This invention consists in an ore-washer wherein are combined alongitudinally-inclined cradle having two openings at the lower end thereof-one next to the bottom for discharging the ore and the other above the bottom for discharging the sand and water-either or both openings being adapted to be closed at will, a fixed shaft extending longitudinally through the cradle and having the latter arranged to rock thereon, and ore-agitators fixed to the cradle and shaft, respectively, to 00-01)- crate with each other; also,in the combination, with the foregoing, of a. bifurcated hopper whiclrextends into the cradle, at theupper end thereof, and straddles the shaft, bringing the delivery end of the hopper below it.

This invention is illustrated in the accompanying drawings, inwhich Figure 1 represents an end view. Fig. 2 is a side elevation. Fig. 3 is a vertical longitudnal section. Fig. etis a vertical cross-section. Fig. 5 is a plan or top view. Fig. 6 illustrates details ofconstruction.

Similar letters indicate corresponding parts.

The letter A designates the cradle; 13, the shaft; E G, the ore-agitators, and L the hopper.

The cradle A has an approximately semicylindrical shape, and the flat top is hinged and locked to the round bottom or body thereof for convenient accessto itsinterior, the whole being inclined longitudinally. At the lower end of the cradle A are two openings, IJ, one of which is immediately next to the bottom or shallow part thereof, while the other is above such bottom, and either or both of which are adapted to be closed by suitable covers. (Not shown.)

The shaft B is polygonal at its opposite ends, where it restsin bearings I), applied to a suitable frame, so that it occupies a fixed position, and the shaft extends longitudinally through the cradle above its center of gravity, while those portions of the shaft at or opposite the ends of the cradle are rounded, the cradle being provided with bearings O therefor, whereby the cradle is adapted to rock on the shaft. This shaft B is placed in an inclined position for the purpose of bringing the cradle into the desired plane.

The agitators E are fixed to the shaft B, as by means of set-screws 0, and consist of segmental spiders terminating near the bottom of the cradle A, and having laterally-projecting spurs F.

The agitators Gare fixed to the cradle A by bolts or other suitable means, and alternate with the agitators E,\vhile they are composed, like the latter, of segmental spiders having laterally-projecting spurs H, which are between those of the agitators E, allowing the agitators to pass and repass each other.

The hopper L extends into the cradle A, at the upper end thereof, through a suitable opening, and it is bifurcated at the lower end, as indicated in Fig. 4, to straddle the shaftB, so that the delivery end of the hopper is brought below the shaft and near the bottom of the cradle.

In the upper part of the hopper N is a riddle, M, which is removable, being provided with suitable handles.

In applying the apparatus to use the opening J is closed and the ore is introduced into the hopper L, together with a suitable quantity of water, thence passing into the cradle A, while at the same time a rocking motion is imparted to the cradle, so that as the ore descends on the bottom thereof by its inherent gravity it is subjected to the action of the agitators E G, In this manner the ore is divided and washed, and the heavy or metallic particles are allowed to collect on the bottom of the cradle at or upward from its lower end,while the water overflows through the upper opening, I, carrying with it the sand or earth.

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

1. The combination, substantially as hereinbefore described, of the longitudinally-iuclined cradle having two openings at the lower end' thereof -one next to the bottom for discharging the ore and the other above the bottom for discharging the sand and Water--thefixed shaft extending longitudinally through the cradle ICC the ore-agitators fixed to the cradle and shaft, respectively, and the bifurcated hopper extending into the cradle, at the upper end thereof, and straddling the shaft.

- In testimony whereofI have hereunto set my hand in the presence of two subscribing Witnesses.

and having the latter arranged to rock thereon, and the ore-agitators fixed to the cradle and shaft, respectively.

2. The combination, substantially as hereinbei'ore set fortln of the longitudinally-inclined cradle having two openings at the lower end thereof-one nextto the bottom for discharging the ore and the other above the bottom for I discharging thesand and water-thefixed shaft extending longitudinally through the cradle and having the latter arranged to rock thereon,
