THOMAS VARNEY, OF sAN FRANCISCO, CALIFORNIA.
|MPROVED AMALGAMATOR.
Specification forming part of Letters Patent No. 37,185, dated December 16, 1862; -Reissue No. 1,924, dated March 2B, 1865.
following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a vertical central section of a pan with my improvement, a: w, Fig. 2, indicating the line of section. Fig. 2 is a 'horizontal section of the same, taken in the line a: a, Fig.
. 1. Fig. 3 is a topview of the interior of the pan with a portion of the upper mullerand its shoes broken away. A
Similar `letters of reference indicate corre-l sponding parts in the .dierent figures.
The nature of my invention consists in providing and suspending within`the body7 of the amalgamating-pan and in the pulp to be ground and amalgamatedastationary curved plates in such number and of such size and form as to counteract the outward tendency ot'ft-he pulp above the upper mullereaused by the rotation of the same, and to turn the rotary current inward and guide it to or toward the center 4of the pan, andatthe same time to secure a thorough mixture of the pulp. To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation with reference to the drawings, and, in order to do this the more clearly, I will also describe a pan in which the said invention may be used. The body of the amalgamator consists of a pan or tub, A, supported by `proper framework, B, with al cover, C, through which there is' a opening for the introduction of the pulp to be amalgamated, which consists of crushed ore and water. 'Ihe cover may be placed upon the pan loosely or made to tit and fasten -to it water-tight. The latter method .will allow the pan toy be filled more nearly full of pulp, the cover preventing any spattering or overflow of the pulp, and also facilitating the return of the same to or toward the center. The pan may be used without a cover in which case the same shouldl not be filled full as otherwise. Within and on the bottom of the pan and secured to it lies' the lower or stationary muller, D, being a circula-r plate.
This muller may be made whole or in sections. It 'may also be furrowed, slotted, or grooved l in any manner desired.- .Above the lower 'muller is the upper or rotating one, E, of like general form, with a diameter somewhat less tha't of the interior of thepan. To the lower face of the upper muller are attached shoes of any desired number and form, with proper spaces between them, through which to allon1 an abundant flow of pulp from the center to thel circumference, when the lower face of the shoes are in contact with the upper face of the lower muller. At or near and around the center of the upper muller are openings G through it, of sufficient number and size to allow an abundant dow of pulp through them downward and outward between the mullers and grinding-surfaces.. Otheropenings of any desired number, form, and position may be made through the upper muller.
The bottom of the pan and the mullers, in-
stead of being flat, as shown in the drawings,
may be of any other desired form.
The upper muller is adjustable vertically,
and made to rotate horizontally by meansv of the machinery and gearing shown in Figs. 1 l
and 2, or by'any `other proper means.
Within the body'of the pan are suspended curved plates H, extending in `length (horizontally) from the inner surface of the pan around in the direction of the Inullers motion to points near the center of the pan and about one-third of the circle in advance of those from which they start, respectively, if three plates be used, and about one-half of the circle if two plates be used.
In case the mullers and bottom of the pan are made to incline downward from the circumference toward the center, or if the speed of the upper muller is slow, or the central openings in the upper muller are large, or if there are openings in it nearer the circumfer. ence, as well as for various other reasons, the curved plates may extend to a less distance from the innner surface ofthe pan toward the center. In width (vertically) these plates extend from near the upper surface of the upper muller upward two-thirds of the dis,-
tance to the top of the pan, more -or less.
`and amalgamation to tke place. 'lhe rota` The width of the plates may be less in proportion to theircircumference in number.
When the plates extend to near thecenter of the pau, all their inner ends are attached.
rigidly to the ring I, and are suspended bya rod, J fastened to each plate and running up through the cover (or in the absence of a cover through a, crossbar) and hand-wheel `K, by which the saine may be adjusted vertically. i
'lhe plates may extend upward quite to the cover and be permanently fastened thereto, or, when short, may be suspended to the sides of the pan.
The operation is as follows: The pau beingproperly charged with pulp and quicksilver,
and the proper speed being giveuto the upl ver, and thence upward into the body of th pan, thereby causing the ore to be pulverize tion of the upper muller causes the body of the pulp in the pan to revolve with it, and this motioucauses the pulpto seek the eircumferenceof the pan and tend to assume a concave form; but this circularcurrent and outward tendency of the pulp are niet by the curved plates and turned inward toward the center, allowing the pulp to go downward through the openings through the upper muller and outward again between the mullers, and also causing the surface of the pulp to remain nearly level and the same to be thoroughly mixed.
Having thus' described my invention, what I claim as new', and desire to secure by Letters Patent, is-
Thecurved plates, constructed substantially inthe manner and used as and for the pur poses set forth. v
