JOSEPH S. SMART, OF TROY, NEW YORK.
IMPROVEMENT IN PAPER-PULP 'SEPARATORS.
Specificationforming part of Letters Patent No. 182,137, dated September 12, 1876; application filed I May 22, 1876.
To all whom it may concern:
Be it known that I, JOSEPH S. SMART, of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Paper-Pulp Separator, of which thefollowing is a specification:
In the accompanying drawing, Figure 1 represents a top view, with parts broken off, of my improved paper-pulp separator; and Fig. 2 is a vertical longitudinal section of the same on the line a; m, Fig. 1.
Similar letters of reference indicate corresponding parts.
The object of my invention is to utilize the coarse and heavy stock that is collected at the bottom of the settling-vats in the manufacture of paper, so as to draw the same ofi to regrind, and conduct it back to the vat for use.
The invention consists of a settling-vat with one or more revolving bottom arms, that convey the heavy particles of pulp to an outlet, and, by a connecting-pipe, to a grinding-engine, that forces the ground particles through a goose-neck pipe back into the vat.
In the drawing, A represents the usual settling-vat, to which thepulp is supplied in the customary manner by astuft" pump through an outer casing, a, and interior partition b.
The pulp is miXed in the vat or separator A with a sufficient quantity of water, so that the fine pulp passes out to the paper-machine,-
while the heavier and coarser stock settles to the bottom.
Hitherto this stock had to bedrawn off as are attached to a central revolving shaft near the bottom of the vat, the same being so constructed and slowly revolved that the heavy particles of stock are conveyed to an outlet,-
at, from which it is passed, by the pressure of the column of pulp, through a bottom pipe,
The upper disk is so suspended as to be raised from or lowered to the bed-plate, obviating the necessity of the shaft running through the bed-plate and casing to a seat or step below,
and leaving thereby the inlet-opening entirely free for the unobstructed en trance of the heavy pulp particles from the vat. is provided with radial wings, that take up the ground-up particles and force it up the pipe F into the casing a, overcoming by their pump-action the height of the delivery-pipe above the level of the pulp in the vat.
The grinding-engine and pump combined form an important point of my invention, and
I reserve myself the right to file a separate application for Letters Patent for the same.
Having thus described my invention,I claim as new and desire to secure by Letters Patent- A A grinding-engine, E, and separator A, connected by pipe D and outlet d, in'combination with the partition I), pipe F, and easing a, and the curved revolving arms 0, arranged on a central shaft of vat or separator, as and for the purpose specified.
