GEORGE L. HODGE, OF BOSTON, OHIO, ASSIGNOR OF ONE-HALF TO THE AKRON PAPER COMPANY, OF AKRON, OHIO.
MIXER FOR PAPER-MAKING MACHINES.
SIEGIFIGATION forming part of Letters Patent No. 710,456, dated October 7, 1902. Application filed December 15,1900. Serial No. 39,958. (No model.)
To all whom, it may concern:
Be it known that I, GEORGE L. HODGE, a citizen of the United States, residing at Boston, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Mixers for Paper-Making Machinery, of which the following is aspecification.
My invention has relation to improvements in paper-making machines of the cylinder type. Ileretofore in such machines the pulp in passing into the tank in which it is deposited on the cylinder moves in straight lines, and thus the particles of pulp lie practically in parallel lines and is in this condition taken up by the cylinder and thence transferred to the felt, as a result of which the paper is weak in one direction and has what may be termed a distinct grain, so that it tears readily in that direction, while it is much stronger across this grain. This is found to be objectionable, because the paper is not uniformly tough in each direction, often resulting in tearing of packages it is used to inclose.
The object of my invention is to overcome this objection and to so agitate and mix the fiber of the pulp that it will enter the cylinder-tank without this grain, thereby practically interweaving the particles of the paper in its construction. 1
To the aforesaid object my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described and then specifically pointed out in the claims, reference being had to the accompanying drawings, forming a part of this specification.
In the accompanying drawings, in which similarreference-n umerals indicate like parts in the different figures, Figure 1 is a side elevation of a part of a paper-making machine embodying my invention; Fig. 2, a plan of the same; Fig. 3, a section of the same atthe line as so of Figs. 1 and 2, and Fig. 4 a section at the line y of Fig. 2 looking from the left.
Referring to the figures, 1 is so much of the machine as incloses the cylinder-tank, and 2 the cylinder, journaled in bearings at each side of the machine, the driving mechanism of which is not shown, as it is of ordinary form of construction. Adjacent to this is the pulp-box, from which the pulp passes under an adjustable gate Ato the cylinder-tank, which gate is raised and lowered for adjustment by hand-screws 5, each secured against accidental turning by jamnnts 6.
At each end of the pulp-box 3 and internally connected therewith are end boxes 7, into which the pulp primarily flows through pipes 8 from the pulp-tanks 9, that receive the pulp from the beater-engines through a pipe 10, each of which tanks is provided with water-pipes 11, that enter the tanks 9 at an angle and serve to dilute and agitate the pulp therein as desired. As thus far described the construction is of the ordinary construction common to these machines. The pulp entering the boxes 7 has some pressure due to gravitation and the momentum due to the water entering through the pipes 11. To increase this pressure, so that the pulp and water entering the pulp-box 3 will be agitated and caused to circle about therein, I provide in each of the boxes 7 an adjustable piston 12, regulated by a hand-screw 13, by which it may be raised and lowered to increase or diminish the capacity of the outlet. In the drawings in order that the nature and operation of my invention may be more readily understood and distinguished I have shown the right box onlythus provided, the other remaining in the common form of construction.
In operation the piston 12 is raised or lowered as the requirement of the machine demands to produce the desired result. By lowering the piston 12 the size of the outlet of the box 7 will be reduced, and as a result the pulp passing into the pulp-box 3 will pass through in a narrower stream and receive increased velocity due to the narrow stream entering the box 3 with more rapidity than if the whole opening was free, on the general and well-known principle that where the discharge is reduced in size the force of the flow is increased, thereby causing it to circle about the box, as indicated by the arrows in Fig. 2, and become more evenly incorporated and the tendency of the pulp particles to move in straight lines prevented, thus avoiding the objection before noted and rendering the texture of the paper of even strength in every direction What I claim, and desire to secure by Letters Patent, is
1. In a paper-machine of the kind specified, the combination with the cylinder-tank, of'a pulp-box with an opening into said tank, and closure for said opening, and means for adjustably operating said closure to regulate the flow of pulp therefrom in combination with end boxes opening into said pulp-box, to receive the pulp from the pulp-tank, and vertically-moving pistons in said end boxes to regulate the flow of pulp into the pulp-box, and means, such substantially as described for operating said pistons, substantially as shown and described.
2. In a paper -machine of the kind specified, the combination with the cylinder-tank, of a pulp-box with an opening into said tank, of
end boxes opening into said pulp-box to receive the pulp from the pulp-tank, and means for adjusting or closing the openings from said end boxes, substantially as shown and described.
3. The combination with the pulp-box, of end boxes opening into said pulp-box, the bottoms of said end boxes being below the openings therefrom, and means for conducting pulp into said boxes, of pistons arranged to slide in said boxes to move above and below the openings therefrom, and means for operating said pistons,substantial1y as shown and described.
In testimony that I claim the above I hereunto set my hand in the presence of two subscribing witnesses.
GEORGE L. IIODGE.
