WILLIAM O. RUSSELL, OF LAIVRENCE, MASSACHUSETTS.
MACHINE FOR TEARING WOOD PULP.
SPECIFICATION forming part of Letters Patent No. 426,217, dated April 22, 1890.
Application filed May 1, 1889. Serial No. 309,178.
To aZZ whom it may concern.-
Be it known that I, WILLIAM O. RUSSELL, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Machines for Tearing Wood Pulp, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
\Vood pulp is now generally received at the mills in sheet form, and in furnishing it to the beating-engine it clogs under the engineroll and it is necessary to punch it through with a wooden paddle. Therefore much. time is consumed in furnishing the engine with material.
This invention has for its object to construct a machine for tearing or breaking woodpulp stock into small pieces for the beating-engine.
In carrying out this invention the machine is so constructed that the stock is fed forward by a pair of feed-rolls over an edge or wall which is provided with many parallel vertical grooves or recesses, and a large cylinder having 011 its surface projecting pins or studs is employed, the axis of rotation of which is parallel to the axis of rotation of the feed-rolls and is located adjacent to the said grooved edge, so that the pins or studs on its surface enter the grooves thereof. The pins or studs are herein shown as provided with flanges and screw-threaded shanks which enter the cylinder, said shanks being thereafter upset at the end to form another flange.
Figure 1 shows in vertical section a machine for tearing pulp-stock embodying this invention; Fig. 2, a plan view of the machine shown in Fig. 1, the shield inclosing the cylinder being removed; and Fig. 3, an enlarged detail of one of the pins or studs which I prefer to use.
The main framework A, of suitable shape to support the working parts, has attached to it a table B. A feed-roll a is journaled in bearings in the main frame-work, and lying parallel with it is its companion feed-roll I), having its hearings in plumber-blocks b, said blocks yielding against springs 6 The stock is fed forward between the feedrolls a I) over an edge or wall 0, arranged parallel to the feed-rolls' and having many parallel vertical grooves c. The cylinder, the shaft (1 of which is journaled in the main frame-work parallel with the feed-rolls, is 10- (No model.)
eated adjacent to the grooved edge e, and the surface d of the cylinder has many pins or studs (P, which, as the cylinder revolves, enter the grooves o of the edge 0.
The pins or studs (1 are herein shown as consisting of a projecting or exposed por tion, an intermediate flange 2, and a screwthreaded shank 3, and the surface of the cylinder is tapped to receive the screw-threaded shank and recessed to receive the flanges, and after the said pins or studs have been screwed into place the opposite ends thereof at the inside of the cylinder are upset. The cylinder is inclosed within a suitable shield e.
A belt-pulley f is preferably secured to one end of the shaft (Z, and a toothed gear f is secured to the opposite end of said shaft, which gear f meshes with a toothed gear f secured to one of the feed-rolls, as a. The feed rolls have two intermeshing toothed gears, as 5, by which power is transmitted from one to the other.
I do not desire to limit my invention to the precise construction of parts shown, as they may be easily changed.
By this machine it will be seen that as the material is fed forward over the edge e the pins or studs tear off pieces by passing down through the grooves.
I claim-- 1. In a machine of the kind described, the feed-rolls and vertically-grooved edge over which the stock is fed, combined with the cylinder having pins or studs which enter the grooves of the said edge as the cylinder revolves, substantially as described.
2. In a machine of the kind described, the feed-rolls, one of which is yielding and the edge parallel thereto and having parallel vertical grooves, combined with the cylinder having pins or studs which enter the grooves of the said edge, substantially as described.
3. I11 a machine of the kind described, the feed-rolls and parallel edge over which the stock is fed, combined with the cylinder having pins provided with flanges 2, screwthreaded shanks 3, and upset ends, substan tially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
\VILLIAM O. RUSSELL.
