Specification forming par-t of Letters Patent No. 196,174, Adated October ld, l.8 77; npplication`lorl October 24, 1876.

ne it known that I, JOHN H. WILHELM, of Deliver, in the countyof Arapahoe and State of Colorado, have invented a new and useful lmprcved'01'e Washing. and Amalgamati'ng Machine, which I .will call the Adjustable Amalgamator 5" and AI do hereby declare that (the following isa lfull, clear, and `exact description of the constructionfalid operation of I- the same, reference being had'l to the accompacation, in which- E i Figure l is an end view of mymachine;

rThe object of 'my invention istofseparate" .and gather .the native gold, bothl coarse and fine, from the auriferousdbris of placer-mines where there is a scarcity of water, orwhere it cannot be had without great expense-in suicient quantity to collect the goldlby'the ordinary methods.

metallic gold lis thoroughlyv tumbled and dashed about, and constantly kept incontact with a sufflcient'supply of water, thus usinga est particles.

The machine isso constructed -that it'can4 readily be adjusted .to all'kinds of dirt by giv# l ing 'it' a less or greater inclination, and thus- Wash the auriferous dbris more or'less thor.- oughly, 'as from its character maybe required.

.The position `of the ym achine.with reference' to' the supply of water is such as to allow the surplus or waste water"that drains from the tailings readilyto ilow back 'to the pump,

whereit may be re-used, it being an. object,` while saving the gold, also, as much aspo'ssible, to save the,- water. The economizing of -1abor,.also, 'is attained in the mechanism of the machine, it being provided vwith the means of disposing, to some extent by .its own action,of

the tailings, and in beingl so constructed as to be taken apart easily, thus rendering it portable.

The machine is'supported by a shaft, P", l

Figs. 3, 6,10, revolving inthe adjustable jonrnal-.boxes jj', resting on the postsPl. P4, Figs. 1,. 6. 1t is placed overthe water-tank T, Figs. 1,6. Figs` l, 6, 10, is awater-tight metallic cylinder, of any desirable length and diametergradually expanding from some point, asz', into the receiver o, and iprplonged from a .into the metallic screen R' and short cylinder A, Figs, 1%, 6, 10. The wheelfsupports, Fig.1 2', are placedat suitable .distances apart in the cylinder n, screen. R', and cylinder A. The

metallic bars r', Figs. 2, d0, extend throughout n R' A, Figs. 1%, 6, 10. Being placed atshort distances from each other, they form narrowtroughs that aid inf distributing the water `more equally through/n. The bars 1r may b e made of any suitable sizeandl style.v s', Figs.

1, 2, 10, represents flat iron bars of greater width, forming narrow shelves that aid, wheny n and RC are revolving, to elevate the dirt and water, .allowing them to fall, gradually onto the mass below, thus subjecting t toa thorough scouring and washing.

The rinrb' Fi 2 made '0f cast-iron or any' I suitable material, forms a projection that catchesmore or less coarse'gold 'as the debris R', Fig'. isz, is designed' to .showt-11e nur,

gold, .Water, and the finest portion. of the d- 4bristo pass through its perforations into the cylinder X.n The coarser portion ofthe gravel and sand, with some water, travels on. and fallsas tailings at 3, on' the screen' m', Fig. 6.

- The screen lt terminates. in a y cylinder, A,

The object of incasing the bars r', Figs. 192, 2, 10,' at the termination of R,forming A, (similar to n, and 'of which it maybe regarded as a detached section, separated from by R,)' is'rto retain an almndancel vof water. soias to v receptacle gold.. 4 Y, Y H, Figsf9, 10, is a hub or box into which 'wsferis conveyed by P, Figs. 3. 6, '10. o." is

It is evident, from well-known methods of' transmitting the powerito p'p", which it is'not deemed necessary to describe here, that B and w lmay be 1n-'ade to revolve in the same directionwith the same or with different velocities,

orin opposite directions with the) same or with `different velocities, or either may be made to perform. part of a revolution and then beimmediately reversed. The character o f the auriferous debris must determine the nature and velocity ofthe revolutions of -B and x. Generl ally a slow motion produces the best results.

- To securethe. best resultshe amalgamated plates in x' should be kept in prime condition, Aand to economize time, whilecleaningv them,

may be'replaced'with a second set.'

As the metallicj cylinder w may be of any convenient diameter,- one or more interior amalgamated cylinders may be arranged within it,

and, if desired, the inner surface of l:r'n'iay itself be amalgamated. Amalgamated copper- -wire cloth may also be placed around the screen mated surface will"v R'. So much extra amalg seldom, if ever, be required.
