PAPER AND PULP SCREEN.

Specification of Letters Patent.

"atented Oct. 27, 1914;.

Application filed January 10, 1914. Serial No. 811,421.

employed to draw the pulp through the screen plates; and the object of the invention is to provide a device of this general character havingnovel and improved means i for creating the requisite suction action and wherein such means is positioned to one s1de of the plates.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved device whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully set forth in the appended claims.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in top plan with parts in section of a screen constructed in accordance with an embodiment of our invention. Fig. 2 is a view in front elevation with parts in section of the device as embodied in Fig. 1. Fig. 3 is a view in end elevation of the device as herein disclosed. Fig. 4 is a frag mentary sectional view taken through one of the cylinders herein disclosed and its concomitant parts. Fig. 5 is a horizontal sectional view taken through adjacent cylinders, as herein disclosed. Fig. 6 is a fragmentary view in elevation illustrating in detail the screen plates herein disclosed.

As disclosed in the accompanying drawings, 1 denotes a suitably supported vat provided with a plurality of partitions 2 whereby the chambers 3 are afforded, such partitions being of predetermined height and the chambers thus created are inclosed, 1n any suitable manner, by the screen plates 4. Suitably supported adjacent one side of the vat 1 are the cylinders 5, herein shown as disposed in substantial continuity, each of such cylinders being of such a length as to intersect the ends of two adjacent compartments 3 and being in communication with such compartments, as indicated at (5. EK- tending through each of the cylinders 5 is the common rod 7 adapted for sliding or reciprocal movement therethrough and havmg one end projected beyond an outermost cylinder 5 whereby a suitable operating herem shown as a belt or band wheel 8.

means may be aflixed, such means being adapted to be coupled, in the usual manner, with any source of supply. Fixed to the rod 7 within each of the cylinders 5 and at a point intermediate the communicating ports 6 is a disk 9 which upon recurrent or.

reciprocal movement being imparted to the rod 7 1s adapted to result in the requisite suction action within the adjacent chambers 3, for purposes which are believed to be clearly apparent to those skilled in the art to which our present invention appertains.

In order to impart the requisite reciprocation or recurrent endwise movement to the rod 7,. we herein disclose aflixed to the projected portion of such red the cam disk 10 adapted to travel through the guide-way 11 afforded by the spaced blocks 12, such blocks being herein shown as suitably ailixed to the annular band l l suitably secured to the adjacent end of the vat 1. By this arrangement, it will be observed that as the rod 7 is rotated, the formation of the cam disk 10 is such as to result in reciprocation of the rod and it is thought to be obvious that the extent of reciprocation of the rod can be regulated by varying the pitch of the cam disk.

From the foregoing description, it will be obvious that a paper and pulp screen con structed in accordance with our invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and of the effectiveness with which it performs its requisite functions and it will also be obvious that our invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice.

Having thus fully described our invention what We desire to clann and secure by Let- 7 plates for covering such chambers; of a cylinder common to adjacent chambers and in communication therewith through suitable ports produced in the adjacent wall of the vat, a rod capable of endwise reciprocal movement Within such cylinder, a disk Withinthe cylinder fixed to such rod at a point intermediate the points of communication between the cylinder and the adjacent chambers, and means for imparting reciprocal movement to the rod.

2. The combination with a vat provided topics of this patent may "be obtained for five cents each, by addressing the Commissioner of Patents,

with a plurality of chambers, and screen plates for covering such chambers, such chambers being arranged in a series of two; of a cylinder common to each series of chambers and incommunication therewith through suitable ports produced in the adjacent wall of the vat, a rod common to all the cylinders and directed therethrough and capable of reciprocal movement, a disk fixed to such rod within each of the cylinders intermediate the points of communication of such cylinder with the adjacent series of chambers, and means for imparting reciprocal movement to the rod.
