Description

R. A. MOETON,
SAVE ALL FOR PAPERMA'KERS. No. 193 ,344. Pate nte Juiy "24, 1877.
' UNITED STATES PATENT OFFICE,
ROLAND A. MORTON, OF GARDWELL, NEW BRUNSWIGK, CANADA.
IMPROVEMENT IN SAVE-ALLS FOR PAPER-MKERS.
Specification forming part of Letters Patent No. 193344, dated July 24, 1877 application filed October 19, 1876.
` drawings.
As in the difi'erent Operations of paper manufacturing a small portion of the pulp is liable to run to waste, the object of my invention is to separate and oleanse the same from the water and such impurities as may be mixed with it, by an arrangement of mechanism at once simple, cheap, and efficient.
In the drawings hereto attached, Figure l is a plan View of my inventon; Fig. 2, a vertical longitudinal section through the line x a of plan; and Fig. 3, a vertical cross-section through the line y y of Fig. 1.
Similar letters of reference indicate corresponding parts.
'The tank A is divided into two oonpartments, B andC, by the partition D, except a small connecting-passage at bottom of D.
The drum E, the periphery of which is covered with fine wire-cloth e, is mounted on the hollow shaft H, and is caused to rotate in compartment C by power applied to driving pulley J. Shaft His set in suitable journalbearings, and the escape' of water around it is prevented by packing I. The shaft within the drum has a number of perforations, as at a. By the rotation of drum' E a reverse rotary motion is communicated to the conch-roll F, which lies evenly upon the drum, the axis being parallel with shaft H, and set in suitable bearings h h. The conch-roll has a covering, f, of felt or other fibrous material.
A thin metallic plate or scraper, G, is so placed and adjusted as to incline, with slight pressure, against the conch-roll, for the purpose of removing the pulp adhering to it.
Operation: The water containing pulp, otherwise liable to run to waste, is discharged through a proper conductor into oompa'tment B, whence it flows through passage d into it is separated by the blade or scraper G, falling into a box prepared to receive it. When the operation is completed the water remaining in the tank is discharged at outlet c, carrying with it any grit or sedimentary matter which may have been deposited. So efl'ectual is the working of the machine that scarcely a fiber of pulp is allowed to escape, and the value of that which is saved is enhanced by the thorough cleansing.
I do not claim' to be the inventor of a drum covered with wire-cloth, or of a felt-covered couch-roll, for I am aware that both of these have been in use in the nanufacture of paper, but in a manner and for a purpose quite different from that which I have designed; but
I do claim as my invention and desire to secure by Letters Patent The save-all 77 oonsisting of the tank, sievecovered drum, hollow perforated shaft, and the conch-roller and scraper, substantially as described.
ROLAND A. MORTON.
