IMPROVEMENT IN oREj-'AMALGMATQ Rs.v

` Specification forming part :of Letters Patent No; 199,724, dated f October 9, 1877. l l' i' VTo all whom t may concern: A

Be it known that we, JEANBAPTIsrIi LnY CLERC and MAXLMILLIAN A. CAcnor, ofthe city and county 'of San Francisco, Statel of California, have invented a certain new and useful machine or apparatus for saving quicksilver and iioatgold or other metals inquartzmills, which inventionis fully set forth in the following specicationl `and accompanying derstanding of the invention.

In the said drawings, Figure l is a perspective view of ourimachine or` apparatus. Fig. 2 is a vertical longitudinal sectionthroughl'the center of the machine, and just in frontofthe vertical shaft. Fig. 3 isa. top view of one of the frames and itscups or pans." Fig. 4 is a detail view of the lower part of the apparatus, showing the arrangement of theperforated plates and trays 5 and Figs. 5 and 6 are detail views of the amalgam balls or globules, showing the form of two kinds used in the apparatus.

Shnilarletters of reference indicate like parts in all the figures.

Our invention has for its object to provide a machine or apparatus for effecting, in a greater degree, the recovery of float-gold, mercury, and other valuable metallic particles that, from their exceeding line and minute condition, are carried off with the `heavier and worthless particles from the settler7 of the mill, and thus lost in the tailings It consists in the combination and arrangement of a series of cups or pans,with perforated bottoms, placedone over and above the other, and containing a quantity of metallic balls or globules coated with mercury, the cups or pans being held in a series of rings or frames, to which an independent reciprocating or vibrating motion is given, one after the other, for the purpose of properly agitating the contents of the pan and aiding the passage ofthe stream of slime or pulp containing metallic particles through and among the globules, and bringing the amalgamating-surfaces in thorough contact with the particles as the stream passes from one pan into the other one beneath, by producing a rolling motion of the balls or globules 5 and, in connecfor a better untion andcombination with these cups o-r pans, ;thearrangement and Iemployment of a series lof inclined perforated plates and trays, to still further dividethe stream or slime as it passes out of the machina-and bring the lighter and Valuable particles in intimate contact with the i metallicV amalgamated surfaces thus provided, 1 all of which will be. more fully described here- `inafter. i .f l y lteferring to the accompanying drawings, AfArepresent the frame` of the machine 5 B G C, the 'rings or cIIpLholclinglframes; D D, the vertical shaft,..which givesvmotion to the rings; and E, the pulley, producing theproper rotationof ztheshaft. f f

rlhe parts are arranged one above the other, so that the contents or stream from one pan shall pass through the perforated bottom into the next pan below. They each contain a num-l ber of metallic balls or globules coated with Quicksilver, to catch and retain the ore particles by amalgamation, while the worthless particles pass out from the machine. These amalgamating-surfaces are used in the pans either in the form of balls, as shown in Fig. 5,

of globules united together, one to the other, in groups of three or more, of proper size and length to fit the bottom 0f the pan, as shown in Fig. 6. They are composed of lead, silver, or other metal of suitable weight with which the quicksilver will combine.

The vibrating motion of the pans B is produced by means of the vertical shaft l), which has a series of projections or cams, cl d, working in slots b b in the ring-frames C C. The continuous rotation of the shaft produces a back-and-forth Inotion of the pans, one pan moving just in advance of the other, but always over the one immediately beneath it, so that the pulp or slime or stream running into the pans will always be caught within the rim of each one in passing to the bottom tray. These pans are arranged vertically, either in a single series or double, as shown in the accompanying drawing, whereby two streams of pulp from the settler can be treated, and they are used and arranged, in any required number, to any height.

January 29, 1878 application filed B, the cups or pans with perforated bottoms 5' separate and detached, or they are composed In combination with and beneath each set ofvibrating pans are arranged several overflow trays or troughs and inclined amalgamated plates, t0 still further break up the slime or metalliferous stream and separate the valuable particles.

The tray F receives the current iiowing through the perforated pans, andV holds the heavier particles, while the lighter portion is The number of these plates and their trays may be increased at pleasure beyond those .shown in the machine illustrated in the drawings. They are placed one immediately below and in advance of the other, so that the lighter portion of the current overiiowin g from the trays will pass over the plates, and thus receive and be exposed more thoroughly to the action of the amalgamating-surface. The position of the perforated plates and trays is clearly shown in Figs. 1,2, and 4 of the drawings.

By the use of these metallic balls or globules we are enabled to extract and save the` finer valuable articles from the slime or stream running rom the settler or separator of the mill in a better and more certainmanner than is at present done by machines or apparatus now' in use, so far as is known to us, and by having the amalgamating balls removable from the pans they can be taken out as fast as they become covered, and replaced'by` new ones, and the operation of the machine can thus be rendered continuous.

Having thus fully described our invention, what we claim as new therein, and desire to secure by Letters Patent, is-

1. The series of cups or pans'B B, with perforated bottoms, arranged vertically one over the other in supporting rings or frames C C, to which a vibratory motion is given, the said cups or pans containing and being used in combination with a series or number of balls or globules of lead or silver coated with quicksilver, constructed and arranged to operate together substantially as set forth.

2. In combination with the series ofpvibrating cups or pans B B, arranged and actuated substantially as hereinbefore described, the series of troughs ortrays F F1 F2 and inclined perforated and coated platesG G', arranged as herein described, for the purpose set forth.

3. The combination, with the series of frames C, carrying cups or pans B,varrangedas described, of the vertical camshaft E, for imparting a vibrating motion'to such frames and cups, substantially as and for the purposesv set forth.

Inl testimony that we claim the foregoing we have hereunto set our hands this Zdday 0f August, 1877.
