GEORGE S. THOMPSON, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN HOPPERS FOR GRINDING-MILLS.
Specification forming part of Letters Patent No. 138,212, dated April 22, 1873; application filed July 5, 1872.
To all whom it may concern:
Be it known that I, GEORGE S. THOMPSON, of the city and county of Philadelphia, and
, State of Pennsylvania, have invented an Im- 4 are sectioned elevations of Fig. 2.
A, Fig. 1, is a grinding-mill, and B the hopper of the same. Its spout O, or part which conveys the paint or other wet stuff to between the stones to be ground, (as shown in dotted lines,) is cylindrical or straight on its exterior, and cone-shaped (or tapering) on its interior, the base of the cone being down, as shown at Figs. 2 3 4. The cylindrical exterior permits the hopper to rise and lower by means of the lever D. The gradual widening of the conical interior prevents the paint from obstructing and sticking, and feeds it easily and freely to the stones.
I claim as my invention- The hopper B, in combination with the spout 0, having a cylindrical exterior and a tapering or conical interior, both rising and lowering or adjustable together, substantially for the purpose shown and described.
In testimony whereof I hereunto sign my name in presence of two subscribing witnesses.
GEORGE S. THOMPSON.
