IMPROVEMENT "\l TRAPS FOR AMALGAMATiNG-PANS AND SETTLERS.

Specification form'ng part of Letters Patent N 0. 173,492, dated February 15', 1876; application filed I December 18, 1875.

To all whom it may concern;-

Be it known that I, ALMARIN B. PAUL, of San Francisco, San Francisco county, State gamating-Pans and Settlers; andl do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention and improvements without further invention or experiment.

My invention relates to a device the object of which is to obviate the necessity of stopping the machinery in order to clean up amalpan or other vessel A I make a hole at some point near its outer rimor periphery, into which I screw a short tube, b, from the bottom up into the pan. In the lower end of this tube I screw another piece of tubing, 0, to the lower. end of which I attach a hollow globe or other suitable reservoir, D. This reservoir or receiver can be made in two parts, as shown, and united atthe middle by flanges, so that the lower half of the globe can. be removed when desired. A tube, 6, projects downward from the bottom of the globe or reservoir D, .which has a screw, f, turned into its open end, so as to serve as a plug for closing the hole. A small hole, g, is made diagonally through the lower end of the tube 6, so that its upper end will communicate with the opening which is closed by the screw f at a point which will up into the tube, but provides a vent or passage when the screw is partly turned out or withdrawn.

The globe D and tubes b and a will be kept constantly filled with mercury, and, as the amalgam accumulates in the amalgamating-pan or other vessel with which the. tube b connects, it will descend through the tubes by its superior specific gravity to the lowest party of the v globe or trap, from which it can be removed by withdrawing the set-screw f, soas to uncover the upper end of the diagonal vent-hole g, and allow the amalgam to pass out.

A tube, G, is connected with the upper portion of the globe, which is long enough to carry the discharge of quicksilver to the desired point. At the end of this tube G an elbow, h, is attached, so that it can be turned to any desired position about the end of the tube G, and another tube, 5, is serewedorotherwise secured upon the upturned end of the elbow. This tube *5 is long enough to extend, say, two or three inches above the upper end of the tube I), which connects with the vessel to the elbow h. This dialor quadrant is graduated, as shown at Fig. 2.

.The operation is as follows: Before charging the pan or other vessel with ore or water the tube 2' is placed in a vertical position, and mercury poured into the tube 1) until the reservoir and pipes are filled. The mercury will then stand in the pipe 2' 011 a level with the mercury in the globe or reservoir. The pans or other vessels are then filled with water up to the lowest point at which it isgenerallydischarged during regular running. The elbow h is then turned upon the end of the tube G, so asto lower the upper end of the pipe 6 by turning it in a circle until the mercury shows itself ready to drop from the'nozzle or curved spout J. This point is noted on the dial or indicator as the point at which all surplus mercury and amalgam can be drawnofl'. After the pan'has run awhile, and amalgam has been deposited in the globe or trap, the

mercury will'rise in the tube i, when, by again lowering this tube, the height of the mercury can be ascertained by the drip, and a sufficient quantity of amalgam and. quicksilver drawn oft tnrough the vent-hole g, as above described, until the proper level has again been attained.

.This processof removing the accumulated Prion filled as full as desired.

amalgam and surplus quicksilver cambeaccomplished at any time .whilehthes. pans are working, without interfering with their operation in the least, or stopping the machinery..

It is desirable to give the vessel to the bottom of which the tube b is connected a slight inclination toward the point of discharge, say of one-eighth of one inch to the foot.

When running, the pipe 5 shouldremain in a vertical position, and the vessel can be kept to run 0E mercury, lower the pipe or tube i gradually as the pressure lessens, for flow ofmercury, and until it reaches the desired point, as indicated on the dial.

When it is desired-- the trap-and pas-while d-rawi-ngpffjtheamalgamvand quicksilver fronr theyreservoir.,

To wash the reservoir or trap out, so' as to remove-an y clinging or lodged amalgam, throw in clean mercury, which will dislodge and carry it out.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent, 1s-

1. In combination with a trap or reservoir, for collecting amalgam from pans, and settlers, I claim the pipe Gr; swiveling-elbow h, and tube 6, for the purpose specified.

2. The fixed dial or indicator K, in combination with the swiveling-tube i, tubes G and 0, and trap D, substantially as and for the purpose above described.

In witness whereof I hereunto set'myhand.
