PATENT OFFICE.

STAMP-MILL.

SPECIFICATION forming part of Letters Patent No, 753,602, dated March 1, 1904.

Application filed May 27, 1903.

To all whom it may concern:

Be it known that I, WILLIAM A. MERRALLS, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Stamp-Mills, of which the following is a specification.

My invention relates to improvements in stamp-mill mortars, the object of my invention being to provide a stamp-mill mortar which shall be more economical and effective than those heretofore in use.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the claim. 7

In the accompanying drawings, Figure 1 is a vertical section of my improved mortar. Fig. 2 is a horizontal section on the line A A of Fig. 1.

Referring to the drawings, 1 represents the mortar proper, which has openings on all four sides, as shown, said openings being all provided with guides 2 to receive screens 3.

4 represents a plate upon which the pulp falls and flows toward the front, said plate having a wall 5 along its rear end and side edges.

6 represents an amalgamating-plate coexten- Serial 1%. 158,983. (No model.)

sive in size with the screens and which can be substituted for a screen in one of the openings, preferably the rear opening, as shown in the drawings. Said plate has horizontal troughs or riflies 7 for catching the precious metal. This plate is of special advantage in milling orecontaining free gold; otherwise a screen would preferably be used in the rear opening.

The advantage of this construction is that nesses.
