GOLD SAVING AND AMALGAMATING MACHINE. i

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application filed July 29, 1911. Serial No. 641,390.

Be it known that I, ROBERT BEYRLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Gold Saving and Amalgamating Machine, of which the following is a specification.

This invention relates to certain new and useful improvements in amalgamating machines, and the objects thereof are to provide an improved and simplified structure of this character, which embodies novel means for effecting adjustment of the upper riitle member, and to otherwise generally improve machines of this type.

In the drawings, Figure 1 is a view partly in side elevation and partly in section of the present invention; Fig. 2 is a fragmentary top plan view; Fig. 3 is a fragmentary bottom plan view of the upper disk; Fig. 4 is a sectional view of one of the division ribs, and Fig. 5 is a perspective view of one of the ritlle cleats.

A circular receptacle A is provided with a central support A in which a spindle H is journaled, the spindle having an annular shoulder H which engages the upper end of the support A the lower end of the spindle being engaged by set screws H which are projected through the support to impinge against the spindle to prevent upward movement of the latter.

Loosely mounted on the spindle H is the hub E of a frame which has an annular flange E at its lower end which latter has the upper amalgamating ring C secured thereto by screws C Inclined rods D are adjustably secured by nuts to lugs E of the frame E and are also secured to the ring C adjacent the periphery of the latter. On

. the upper face of the ring G a plurality of ribs D are secured, these ribs forming a number of divisions thereon. On the under face of the ring C riffie cleats R are secured.

A cap plate J seats on the upper end of the hub E and is secured to the latter by bolts K. An eye bolt L is threaded through an opening provided therefor in the cap plate and has its lower end bearing on a washer L which latter seats on the top end of the spindle H, so that when the bolt is turned by the hand wheel M that is rigidly secured'thereon, it will effect raising or lowering of the cap plate and the frame connected thereto. A look wheel N is used to engage on top of the cap plate J to hold the bolt L against accidental turning.

A pulley P engages over the cap plate and the upper end of the hub E and is secured to each by set screws P whereby power when applied to the pulley effects rotation of the frame and connected parts. The pulley is made of dish-shape so as to act as a hopper for feeding material to the machine through the downwardly extending inclined pulley.

The bottom amalgamating plate which is ring-shaped is secured to the bottom of the receptacle A and is covered with suitable amalgamating material C the ends of which pipe P that is connected to the ing material W, preferably pitch.

The central support A is surrounded by a sleeve A arranged in spaced relation thereto and covered on its exterior by amalgamating material 0*. By this construction any overflow from the tub will pass over the open top end of the sleeve and escape downwardly through the interior thereof to a suitable drain, not shown.

In operation the crushed ore or other material is received in the receptacle A, the latter being nearly filled with mercury and water, the ore or other material passing between the upper and lower amalgamating rings whereupon any gold or the like is collected on the parts C C (1 and the riffle cleats R.

What is claimed is:

1. In an amalgamating machine in combination with a receptacle, an upper riffie member rotatably mounted in said receptacle and a pulley connected to said member for rotating same, said pulley being of dishshape so as to receive material that is to be fed to the receptacle and a downwardly inclined pipe extending up through the pulley bottom and extending down into the receptaoleto feed the material from the pulley to the upper rifile member at a point substantially central of the radius thereof.

2. In combination with a receptacle, a central sleeve projecting through the bottom of said receptacle, a support within the sleeve spaced therefrom, a spindle having its lower end rigidly secured to the support and having acentral shoulder which seats on the l upp er end of. the stipp'ort, a riflfle p1ate, said serew 'being for ehgagernent with member having a hub that is received over thetopend of the spindle. the upper end; of sai d-rs pindle' a; cap plate V V ,1 r
