TO ADL- WHOM IT-MAY CONCERN:

Be it known that I, ABNER BASSETT, of the city of Virginia, county of Storey, State of Nevada, have invented certain new and useful improvements in\Afmalgamators for working gold and silver-bearing ores and extracting the' precious metals, called Bassetts Ama-lgamatorg and I do hereby ldeclare the-following description and accompanying drawings are suliicient to enable any person skilled in the art or science to which it most nearly a'ppertains, to makel and use my said invention without further invention or experiment.

The nature of my'invention -consists of a barrel or other suitable vessel, with a hollow shaft passing longiv tudinally through the centre, by which heat is introducedby means of exhaust steam, or otherwise; the barrel or cylinder being inclosed in a shell or bath whereby hot air is introduced aroundv the entire circumference of the barrel, aswell as through the centre. The 1pulp not coming in contact with the steam, important chemical `'changes are electedby the heat in itself. Inthe drawings- `Figure l is a side elevation. I

'a a a, stuffing-boxes; b, pulley by which the machine is driven; c, hollowshai`t, open at both ends, for introducing the steam pipsd ZZ', d being the induction pipe, and d' the escape pipe. e is Aa barrel or other shaped suitable vessel, constructed of iron or other suitable material, through which the hollow shaft c passes; the shaft being constructedl tight, so as not to admit the steam or heat directly into the pulp or ore to be amalgamated, but imparts its influence uponv the outer circumference of the barrel or vessel which contains the pulp'. f is a man-hole'of barrel; y, discharging pipe. The outside shell or bath, hin which the barrel is revolved, is formed in halve-s, coupled together by'means of lanches and bolts. z' z" are steam pipes; z' is theV induction pipe,` z" the escape pipe. J J are hatchways on the outside shell, .used principally 'or'testingv and discharging the ore or pulp. 4 The whole being mounted upon some suitable frame, the shell resting upon pins placed at suitable distances around the inside of the frame. By this arrangement it is not intended that the shell shall revolve, but-remain stationary, enclosing the barrelthrough which the hollow shafl't or cylinder passes, causing it to revolve `by means ofthe pulley b.- The ore to be amalgamated is placed -in the barrel with the usual accompaniments well known to metallurgists, when the steam or heat is admitted through the hollow shaft, and into the shell through the pipe z', and the barrel slowly revolved until a complete amalgamation is eipecteil. By this arrangement of introducing steam or lient, both on or through and around the pulp, without coming-in direct Contact with it, great beneficial chemical changes are produced, generating gases, and causing a separation of' metals from o bdura-te ores, which is indispensable for :i free amalgamation.

Ha'ving thus described m v invention, I will now proceed to 'state what I claim, and desire t0 secure by Letters Patent; that is to say, I do not claim the use oi' steam For amalgamation of ore.

l What I claim, is

1., The barrel e or its equivalent, having a hollow shaft,'c, passing through it, by which heat is introduced y by exhaust steam or otherwise, substantially as described and for the purpose setforth. l '2. I claim thehot-air shell or bath g, i'or the purpose of .applying heat, by exhaust steam or otherwise, t0 v the out-side of the vessel containingthe pulp, whereby obdurate ores are made to amalgamate more freely, subl stantially as described, and for the purpose specified. I i

3. I claim the application of steam or heat to the ore or pulp, both through and around it, without coming in direct contact with itl.; the said ore or pulp being confined in some suitable vessel, said vessel heingenclcsed in a shell or bath, for the purpose herein set forth.

In witness whereof I have hereunto set my hand and seal this 16th day of August, A. D. 1866.
