SPECIFICATION forming part of Letters Patent No. 547,239, dated October 1, 1895.

Appnanmsied my 17,1895. serial No. 549,636. (No model.) Y

To CLZZ whom it may concern.-

Be it known that I, ERAsTUs S. BENNETT, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State o f Colorado, have inventedcertain new and useful Improvements in Amalgamators; 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 same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in amalgamators, and is specially designed for use with the style of tank shown and described in a previous patent issued to me on the 13th day of March, 1894, being numbered 516,624. This tank' is W-shaped in vertical transverse section and provided with corrugated amalgamated plates having the pockets, cellsor depressions between the ribs closed at the ends. In thesepockets or'cells it is designed that there should be, and there is, in fact,al-` ways some free mercury whichit is intended shall keep the adjacent ribs of the plate moist under the influence of the jarring, vibratory motion imparted to the machine during use, thus increasing the efiiciency'of the plates. It often happens that the machineis subjected to jars of sufficient .magnitude to throw or siderable quantities, thus suddenly depriving a cell of its free mercury without accomplishing any useful object. To obviate this sud-V cury from the cells, and at the same time form a hiding-place for the mineral or amalgam, where it is protected from the sand and gravel, is the object of my present invention'.A

To this end the improvement consists of the In the accompanying drawings is illustrated an embodiment of the invention.

Of the drawings, Figure lis a vertical transverse section of the amalgamating-tank provided with my improvement. Fig. 2 is an enlarged fragmentary viewof the same." Fig.

by the arrows in Fig. 1. Fig. 4 is an end or edge view of the same. Fig. 5 is a perspective view in detail of one of my improved Y plates.

In the views, similar reference-characters indicating corresponding parts or elements, let thenumeral 5 designate the tankprovided with corrugated plates 6, having a backing or filling 4, and provided with pockets, cells, or depressions?, closed at the ends, as shown at 8. Within these cells or pockets are placed in an inverted position'the concavo` convex or troughshaped auxiliary plates 9, which may be retained in position either by gravity or frictional contact. These plates, when in position, preferably extend above the corrugations, heads, or ridges on either side, and thus formV a check for the mineral or amalgam passing down the sides of the tank,being thus directed into the cell beneath, since there is sufcient room around plates ,9 to allow the amalgam and mineral to pass into the cells. The depth or height of plates) may, however, be the same or less 'than the heads on each side, as shown by dotted lines, and designated 9 in Fig. 4.

The ends of plates 9 are closed to prevent the sand from entering at the ends of the cells. The ends of these plates are preferably 4composed of wooden blocks, as shown at lO'in Fig. 5. They may, however, consist of any other suitable material, as sheet metal. This form is shown at 3 in Fig. 4.

It will thus be seen that when plates 9 are infposition the free mercury 'in cells 7 can only escape by passing out around the sides orends of'plates 9, which prevent the escape of this mercury in greater quantities than may be desirable or necessary in order to keep the amalgamated plates in proper condition.

Having thus described my invention,what I claim is Al. The combination in an amalgamator provided with corrugated plates having the depressions closed at the ends, of the inverted trough-shaped auxiliary retainingpla'tes located in said depressions, substantially as and for the purpose set forth.

2. The combination in an amalgamating tank, of the corrugated plates havingtheir depressions closed, or partially closed, at the IOS) ends forming pockets or cells, of the inverted trough-shaped auxiliary retaining plates Closed at the ends and located in said cells or pockets, substantially as and for the purpose set, forth.

3. The eombinationin an amalgamatorprovided with corrugated plates, of the inverted troughshaped auxiliary retaining plates l0- cated in the depressions of the corrugated plates, substantially as described. 1o
