Description
UNITED STATES PATENT OFF-10E.
JOHN W. DIXON, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVED APPARATUS FOR MAKING PAPER-PULP.
Specification forming part of Letters Patent No. 52,543, dated February 13, 1866.
To all whom it may concern:
Be it known that I, JOHN W. DIXON, of the city of Philadelphia and State of Pennsylvania, hay e invented a new and useful Improvement in Apparatus for Making Paper- Pulp; and I do hereby declare the following to be a full and exact description of the same, reference being had to the annexed drawing, making a part of this specification, which represents a vertical longitudinal section of my improved apparatus.
My improvement has for its object the digestin g wood, straw, or other vegetable fibrous material for making paper-pulp, and may be used for boiling rags or bleaching and preparing flax or similar matters.
A a horizontal rotary boiler turning on hollow trunnions c c, and made of iron strong enough to resistoonsiclerablepressure. I would advise at least one hundred and fifty pounds. At E is a covered man-hole for introducing the material.
F and 1 are two perforated diaphragms. A pipe, G H I J R L, extends from one trunnion to the other. At J R S this pipe is coiled in a furnace, B. At P is a rotary or other pump.
The operation of this apparatusis as follows: The material and digesting-liquor being introduced at E, the pump P is started and the fire made in R, which causes arapid circulation up through the coil, in through the trunnion 0, and through the perforated diaphragm, and through the material, and out through the trunnion 0 into the pump, and thence through the coil. The pump P compels a constant circulation. The rotation of the boiler A facilitates the agitation and mixing of the material and of the digesting-liquor, which may be either highly-heated \vater alone or a solution of alkali or other digesting-liquor. Any other heating apparatus besides the coilsuch as a fire below the boilermay be used, and the pump and tube will then be used only for producing a circulation.
Havin g thus described my improvement, what I claim, and desire to secure by Letters Patent, is
1. The combination of the circulating-pitmp and revolving boiler.
2. The combination of circulating -puinp, heatingcoil, and revolving boiler.
3. The combination of one orboth perforated diaphragnis and a revolving boiler and pump, P.
JOHN W. DIXON.
