With the foregoing and other objects in View this invention consists in such novel features of construction combination and arrangement of parts as will be hereinafter. more fully described, illustrated in theac companying drawings and claimed.

In describing the invention in detail, reference Will be made to the accompanyi drawing which shows a verticaltion' of the machine constructed in acct, ance with this invention.

Referring more particularly to the drawings, 14 is a hollow vertical cylinder or drum, the upper end being closed by a fiat top; to the lower end of 1% is attached an inverted hollow truncated cone 1?; to the apex of which is attached a short piece of cylindrical pipe 'Z is a piece of cylindrical pipe held by the collar 6, on the top of said drum and vertically adjustable w i in said collar 6, the said pipe being inserted into the drum 1% through. an opening near the center of the top; 4 a piece of c drical pipe connected tn the upper end the pipe 7. The cylindrical pipe is inserted into the pipe lthrough an opening in the side of the pipe 4, pipe 5 is turned downward inside the pipe it 3 is a piece of cylindrical pipe connected the upper end of the pipe at; 3 is open at the top and has an opening 2 in the side; 12

the gold, silver are practically all separated by the use of a certain prod is a sheet of glass coveri an openin in the top of the drunri l; i1 is a'slidin door in the side of the drum 1%; 9 is a shallow cylindrical cup set in a collar supported Specification of Le 1315. Serial No. 96,555.'

the horizontal bars l0, l0, lined in the sides of the drum ii; the cup 9 is held directly under the pipe 7 and is removable: S a t ndrical ring shaped to fit into the top or the cup 9 the lower edges of the said being bent inward at right angles the upper edges of which are bent 0 award so as to form a flange; 23 and 24- are parts of a supporting frame work; 19 is i t al bar attached at each end to the v of the said frame work; to i is fitted the collar which is atl pipe 15; 16 is a circular around the lower end of a piece of pipe at-' into the sprinkler 16; the bottom of which lly p 13. l 'i ll'Ulli all s] L enin.

The operation of the machine is as follows laid su h as steam, air or water 1S conpressure through pipe 5 pressure downward through the l ercnr r is placed in the ducted by the pipe 21 into which sprays the water l sand and mineral are 'i ii the pipe 3 and Enid from the pipe 5 d 'nineral into the cup mineral into the merx e sand out over the e particles of sand and separate as they pass Y under pressure.

cup. The reason that the lower edges of the ring 8 are turned inward at right an,-

gles is as tollowsz lt is found that in sands containing gold there are often heavy sands such as iron or black sands. When the apforce of the fluid sand and mineral coming through the pipe- 7 sets the mercury in motion flowing down:

Ward in the center ofthe cup .9 thence out-- ward to the sides of the cup thence upward andinward toward the center. The mercury rolls from the sides of the cup to the center in a convex curve leaving a space between the mercury and the sides of the cup. The said heavy sands tend to gather in this space and being heavy will work downward into the bottom of the cup gradually forcing the mercury out of the cup. edges of the ring 8 prevent the said heavy the said space to the bottom of the said cup. These sands will then be carried upward with the other sands and blown ofi" the surface of the The sand and any particles of mercury and other mineral which are blown out of the cup 9 are collected by 13 and 15 into the pan 35.. Power is applied to the cam-shaft 30 and the pan 3:") and the screen 26 are'set in motion, the pan being given a-lateral motion and the screen being held by metal straps rigidly fixed to the screen and to the bar 19 is given a lateral and ver'- tical motion, the vertical motion resulting.

from the resultant bending of the screen. This works the sand from the bottom-ct the pan Strand the mercury is allowed to settle. The motion of the screen really opens the sand so that the heavy mineral may fall The mercury a d gold or silver may then be separated by art.

The opening 2 at the upper side of the pipe 4 serves to admit air and thereby prevent the creation of any vacuum in the pipe silver and the The bent lower the methods known to the which'would interfere With the passage the stream of sand therethrough.

It will be observed that the lower edge q of the pipe 7 is above the upper edge of the cup 9 which leaves a free space through each. The sand may be blown ofi" the surface of the mercury, this sand being collected as explained by the casing'l l and nism to recover any precious metal values therein. s

From the foregoing description taken in connection with the accompanying drawings,,

the advantage of construction and of the method of operating this machine will be readily apparent to those skilled in the art to which this invention appertains, and

.then operated. uponby the separating mechawhile in the foregoing description the principle of the operation of this invention has.

been described together with various features of construction, the combination and' arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.

I claim: I

An amalgama-tor comprising in combination a cup, an ai nalgamating body therein having a substantially adapted to distharge the sand or the like against the surface of said body, the lower end of the pipe being ab ove the up er edge of the cup whereby a free space wi 1 be left through which the sand may be blown off and means for producing a fluid the pipe adapted to assist in projecting the particles agaihst the surface of the amalgamating .body,-a ring fitting around the edgehorizontal surface, a pipe.

jet within of the cup having an inwardly turned flange adapted to prevent sand WOIkiI1g between the amalgamating body and the cup.

In witness whereof I have hereunto ailixed my signature in the presence of two witnesses. I DANIEL DIVER.
