FRIEDRICH VOITH, OF HEIDENHEIM, VVRTEMBERG, GERMANY.
MACHINE FOR ASSORTING WOOD PULP.
SPECIFICATION forming part of Letters Patent No. 289,187, dated November 27, 1883. Application filed J une Q7, 1883. (No model.)
To a/ZZ whom it may concern: i
Be it known that I, FEIEDEIOH Voirn, of Heidenheim, in'the Kingdom of Wrtemberg and Empire of Germany, have invented certain new and useful Improvements in Machines forAssorting Vood Pulp, of whichthe following` is a specification.
This invention has reference to an improved machine for asserting wood pulp in a rapid and satisfactory manner, and it consists of a crank-shaft, the cranks of which are arranged at angles of one hundred and twenty degrees to each other, and of sheet-bands connecting the cranks with reciprocating screens of thin sheet metal, said screens being supported on oscillating steel bands. .The different grades of the pulp are conducted into suitable receivers, and the finest parts with the water into a collecting bottom trough.
In the accompanying drawings, Figure l represents a vertical longitudinal section on line m w, Fig. 2, of my new machine for assorting wood pulp. Fig. 2 is a top view. Fig. 3 shows a transverse vertical section on line N O, Fig. l; and Fig. 4 is a diagram indicating the angles at which the, cranks of the crankshaft are arranged.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, E represents an oblong frame, of timber, at one end of which are arranged the upright standards 7c and Z, which support the bearings of a crank-shaft, a, that receives revolving motion by a beltand-pulley transmission. A fly-wheel, m, serves to carry the crank-shaft over its 'deadpoints. The crank-shaft has three cranks, a a', said cranks being arranged at-angles of one hundred and twenty degrees to each other, as shown in Fig. 4. The cranks are connected by light steel bands g h 11 to the perforated sheet-metal screens A B G, which are arranged vertically above each other, and supported'byfour steel springs, d cl2 cl3 di e cZ e3 c", ffz f3 j, whose lower ends are attached to the frame E. The screens A B C are made of thin sheet metal, and bent up at the sides and at one end, the opposite ends being open to permit the shedding of the different grades of pulp. The nely-ground wood is supplied to the partitioned feed-box G, and conducted over the spout H, which is open at the top to the uppermost screen, A, which has the largest perforations. The coarser parts of the pulp move over the screen A, and over the edge of the same, and over an inclined guide-chute,into the receiver No. 4. The perforations of screen B are finer than those of screen A, so that the finer pulp particles pass through it, while the coarser ones are conducted into the receptacle No. 3. The screen C has the finest holes, and admits only of the passage of the finest pulp particles. The fibers which cannot pass through screen C are collected in receptacle No. 2, while the nest parts pass with the liquid through screen C into a -semi-cylindrical trough, F, and from the same into a suitable receptacle, No. l. As the speed of the crank-shaft is about from four hundred and fifty to five hundred revolutions per minute, the screens move at high speed, and cause thereby the rapid separation of the pulp. As the pulp is not heavy, and as the machine has no parts which are subjected to wear, the machine works in a perfectly noiseless manner and without injurious vibrations, so that it can be set up at any place without heavy foundations and without being screwed down. It separates the pulp into four different grades in a rapid and effective manner. The finest particles are separated from the liquid in the usual manner, and are then ready for use.
I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of a revolving crank-shaft, the cranks of which are arranged at angles of one hundred and twenty degrees to each other, connecting steel bands, reciprocating sheetmetal screens, supported on oscillating steel bands, a collecting-trough below the lowest screen, and receptacles to receive the different grades of wood pulp, substantially as set forth.
In testimony that I claim the foregoing as'
