IMPROVED MACHINE FOR WASHING ORES.

Specification forming part of Letters Patent No. 58,931, dated October 16, [Stili To all whom it may concern:

Be it known that I, MILTON A. WooDsrDE, of Georgetown, El Dorado county, State of California, have invented a new and Improved Machine for Saving Gold and Sulphurets, called Voodsides Endless Blankctg and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the drawings making part of this specification, in which- Figure 1 is a. side elevation with a section through the center longitudinally, shown by dotted lines; Fig. 2, a plan; Fig. 3, an end view from rear, driving-pulleys removed.

rlhe nature of 1n y invention consists of a ma chine drivenbypulleyshavinganendlessblanket of canvas or other material, the ore being introduced upon the blanket through a perforated box placed across the machine. A perforated pipe is also placed across the machine above the oreboX, through which jets of water play upon the blanket, which carry oi the light sand and dbris, leaving the gold and sulphurets, which are carried in opposite direction (the blanket being revolved at an ineline) over the upper end, where they come in contact with a brush, which sweeps them off into a box.

By this arrangement the necessity ot' frequently cleaning and washing the blanket is obviated, and a greater proportion of the gold and sulphurets is saved.

To enable others skilled in the art to make and use my improved endless blanket, I will proceed to describe its construction and operation.

Referring to the drawings, A A are tbe sides of the machine, fastened to an inclined tablet, B, by screws or bolts M M.

Around the rollers C C traverses the endless blanket H, of canvas or other material, with narrow leather or rubber sides or edges G G.

The box I, pierced with fine holes, receives the pulp from the battery or stamps, and distributes it upon the revolving blanket. A pipe, J, having tine jets beneath, serves to ad mit sufficient water upon the blanket to distribute the pulp and carry oft' the sand down the upper slope of the blanket.

Beneath the blanket a roller, K, carrying stitt' brushes L L, continually revolves during the action of the machine, and disengages the sulphurets from the blanket, causing them to fall into the box 1, upon the edge of which the machine is placed, being kept in position by the notch G in the lower edges.

Material is communicated from the power used to the pulley Il, the shaft of which carries the brush-roller K.

By a belt, F, the pulley D, which drives the light handi'oller C, receives motion.

In operation, power is applied to the pulley E by a belt and the machine set in motion. The rollers C (l and blanket II move in the direction of the arrows. The pulp is received from the mill into the box I, and is thence distributed upon II. The strips G G prevent the pulp from running oi the edges. The streams of water from the pipe J carry the light sand oi the lower end of the blanket. The heavy sulphurets remain upon it and are carried over the upper end, and until they come in contact with the brushes L L, which sweep them offinto the box I).

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The endless blanket II and revolving brush K, when arranged substantially as described, and for the purpose set forth.

2. The perforated feed-box I and water-pipe J, substantially as specified, and for the pur pose set forth.

In witness whereof l have hereunto setiny hand and seal this 27 th day of October, A. l). 1865.
