UNITED STATES PATENT OFFICE.
HQRAOE E. HENWOOD, OF KANSAS CITY, MISSOURI, ASSIGNOB TO HIMSELF AND JERE. OHAMBERLAIN, OF SAME PLACE.
GOLD-SEPARATOR.
SPECIFICATION forming part of Letters Patent No. 245,165, dated August 2, 1881.
Application filed April 28,1881. (N model.)
had to the accompanying drawings, forming part of this specification.
My invention relates to gold-separators in which gold is extracted from sand by means of the centrifugal force generated by a revolving hopper; audit consists in certain peculiarities of construction, as hereinafter described.
' Is In the accompanying drawings, Figure 1 represents avertical central section, and Fig. 2 a
plan view. In constructing my improved separator, in-
stead of using the heretofore-em ployed revol vin g hopper having radial arms, I adopta cylin drical hopper, A, as being less liable to spilt the sand and necessitate repeated handling of the same. This hopper ismade open at both ends, and provided at the lower end with an internal annular trough, B, whosolouter wall is formed by the said cylinder. The said.
trough is partially closed at the top by a circular flange, b, which is attached to the. top of its inner wall and inclined upward toward the outer wall. The upper 'rim of the cylindrical hopper is curved inward to prevent the sand from falling into the trough whilebeing poured upon the circular distributer G, and also to prevent the escape of the quicksilver. This dis 3 5 tributer is provided with radial corrugations or channels for conveying the sand more evenly against the wall of the cylinder, and is secured to the hopper by meansof the socket D, which receives the vertical shaft of the support E.
0 At the lower end of this socket is secured a pulley, F, for communicating motion to the machine.
The trough Bis designed for holding quicksilver, which will flow up the wall of the cylinder as the latter is rapidly revolved and unite with 4 5 the gold,which, from its greater weight, will be thrown into the trough, while the sand, falling upon the flange I), will slide downward and out at the bottom of thehopper. By this means the sand is easily and quickly discharged, and willbe thoroughly separated from the gold. An opening in the bottom of the trough, as shown, is designed for drawing off the quicksilver.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, ise 1. In a gold-separator employing centrifugal force, the cylindrical hopper A, having its upper edge curved inward and provided at its lower open end with an internal annular 6o trough,B,having a circular inclined flange, b, in combination with a distributer having radial corrugations,substantially as shown and described. 2. In a gold-separator employing centrifugalxforce, the radially-corrugated distributer .0, in combination with the cylindrical hopper A, having annular trough B, whose inner wall is provided with an upward-inclined flange, b, substantially as shown and described.
3. In a gold-separator employing centrifugal force, the annular trough B, having its outer wall formed by the cylindrical hopper A and the-top of its inner wall provided with an upward-inclined flange, 1), whereby the same shall be partially covered, in combination with a suitable distributer, substantially as shown and described.
