THEODORE H. TRAUERNICHT, OF LEAD CITY, DAKOTA TERRITORY.
STAMP-MILL (DREI-SCREEN.
SPECIFICATION forming part of Letters Patent No.359.750. dated March 22, 1887.
Application filed vTune 1, 1.986. Serial No. $303,746.
To all whom, it may concern:
Be it known that I, THnoDoRE H. TRAUER- NICHT, a citizen of the United States, residing at Lead City, in the county of Lawrence and Territory of Dakota, have invented certain new and useful Improvements in Stan1p-Mill Ore-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the sanne, reference being had to the accompanying drawings, and to the letters and iigures of reference marked thereon, which form apart of this specification.
The invention will first be described in connection with the drawings, and then pointed out in the claim.
Figure l of the drawings is a transverse ver tical section of an ore stampmill; Fig. 2, a perspective view of the screen; Fig. 3, an enlarged longitudinal section of the brush or screen-cleancr; Fig. 4, an end elevation of the same; and Fig. 5, a longitudinal section of a modification of my brush, to be employed where two or more brushes are used.
In the drawings, A represents a stamp, and B the anvil. The stamp-rod A is provided with the usual collar, u', which is raised by a cam, C, on a shaft, c. c is a pulley on this shaft, which is operated by any suitable power mechanism. The pulley o is connected by a crossed belt, D, with a pulley, e, on the brush shaft E, which is thus made to rotate` asv indicated by the arrows in Fig. l of the drawings.
On the shaft E are made fast the arms F F, attached to hubs ff, and each is provided with a slotted arm, f', secured thereto adjustably by means of the screw and nutfifs. Thus it will be seen that as the brushes G wear they may be extended out to take up said wear.
Instead of the usual flat screen, I employ a curved screen, H, which is fastened by the (No model.)
danges 71. h within the ore-box I, whiie the perforated curve projects over the amalgamated plate J and the pan K. These are placed on the usual incline. After the cre is injected through the inclined chute M and water through the pipe N, the mixture is pounded on the anvil B by the stamp A, and the pnl.- verized resultant ore thrown into the screen H, through which the powdered ore passes to and down the amalgama-ted plate. The perforations in the screen become greatly obstructed by particles of matter which collect therein, and to obviate this serious objection to the ordinary screens I use the brushes G, which clear the inside of the screen of any particles as fast as they attach themselves thereto.
In washing gold and silver bearing ores through a screen by a stream of water, the crushed or pulverized ores change their form, some breaking up into elongated particles and others into scales. These are carried against the screen, and greatly obstruct the passage therethrough of the powdered ore. My curved screen presents a larger perforated surface for the space occupied than those in general use.
I am awarepthat it is not new to use rotary brushes over the bottoms of sitters and to employ screens in stamp-mills; but
I/Vhat I claim as new, and desire to protect by Letters Patent, is-
A stamp-mill comprising an ore-box, I, pan K, amalgamated plate J, and curved screen H, the latter projecting from the ore-box and shown and described.
In testimony whereof I afiix my signature in presence of two witnesses.
