IMPROVEMENT IN STOCK-GRINDERS FOR PAPER-PULP.
Specification forming part of Letters Patent No. 156,335, dated October 27, 1874 application filed October 1, 1874.
To all whom it may concern Be it known that I, FRANCIS A. GUsHMAN, of Lebanon, in the county of Grafton and State of New Hampshira'have invented a new and useful Improvement in Pulp-Machines; and I hereby declare the following to be a full and drum, and is pushed up against the revolving surface by means of a hydraulic piston.
The invention will be readily understood by reference to the accompanying drawings, of whichFigure I is a sectional elevation of the improved machine, and Fig. II is a sectional plan of the same.
The driving-pulley A, by means of the belt B, revolves the drum 0, a portion of the interior surface of Which is filled with a plastic composition, in which either emery, quartz, or corundum forms the principal component part, and the asperities of the material thus formed in the drum act upon the contiguous surface of the wood to be reduced to pulp, as will be hereinafter explained. The filling D, constructed as above, is filled into the interior surface of 0, as described, and, consequently, as G is revolved, the surrounding rim will hold the material of D in its proper position in the rim as it is revolved, and prevent its destruction by the centrifugal action of the drum. Within the drum 0 is a stationary disk or table, E, on which the block of Wood F is placed, so as to be operated upon, with its surface resting against the interior surface of D. A hydraulic cylinder, G, has its piston operated upon by either a force-pump or a column of water in a stand-pipe; but I prefer the latter as being the more simple and inexpensive. The piston-rod g presses against the block F, and pushes it hard up to the rough surface of the revolving filling D. The pipe H supplies water to the contacting surfaces of D and F, for the purpose of preventing the surface of D from glazing as it revolves against F.
Having described my invention, I claim The arrangement of the compound drum 0 D, the supporting-table E, and the hydraulic cylinder G, with its piston-rod g acting upon the block F, to hold the block in contact with the revolving surface of D, as described and set forth.
FRANCIS A. GUSHMAN.
