STOCK REGULATOR FOR PAPER MACHINES.

Application led June 2,

To Il wimmz't may concern.'

Be' it known that I, FRANCIS JOSEPH WAL- LACE, a subject of the King of Great Britain, and a resident of the city of Sault Ste. Marie, vin the Province of'Ontario and Dominion of Canada, have invented certain new and useful Improvements in Stock Regulators for Paper Machines, of which the following .is a specification.

This invention relates to improvements in stock regulators for paper machines, and the objects of the invention are to provide simplc and efficient means whereby the flow of pulp will be automatically controlled by the supplying of additional water when it becomes too thick.

Further objects are, to provide means for automatically thinning the pulp in its flow when necessary and whereby the several parts will efficiently and more satisfactorily, perform the various functions required of them.

lVith the foregoing and other objects in view, the invention'consists essentially in the novel arrangement and construction of parts described in the present specification and illustrated by the accompanying drawings that form part of the same.

Referring to the drawing, in which like characters of reference indicate corresponding parts,

The figure is an enlarged vertical section through the pulp box. t

In the drawing, A is the device as a whole comprising the pulp box B of any suitable form and constructed of any suitable material. This box is fed by means of an intake pipe l0 at the top, through which the pulp is delivered into the top portion of the box.

11 is a partition in the box extending vertically. and substantially the full length thereof. leaving at the top and bottom gapsl 12 and 13 whereby the overflowl of the pulp supplied to the upper portion 14 of the box overflows through the passage forme by said partition and the side of the box until it reaches the bottom of the latter.

Thr` main body of the pulp is fed from the top of the box by a conduit or pipe 15 1923. Serial No. 643,028.

into a suitable hopper 17 and through the 50 outlet 1'8 of the hopper where it mixes with the overflow referred to. The pulp in its travel must be regulated to a certa-in consistency so that if it is too thick in the hopper 17 it will not flow easily therethrough 65 and to counter-act this, I provide automatically operated means for injecting water into the pump. i

These means comprise a. float 19'adapted to be raised by-the too float on being raised in turn through suitable connections 21 and 22 releases the valve 23 which connects with suitable pump means that supply the box at the top. 24 is the water line which runs from the valve 23 to 65 the pump and the release of the valve supplies water as required to thin down the pulp mixture.

From the foregoing, the operation of my device and the satisfactory results obtained therefrom will be apparent.A

As many changes could be made in the above construction and many apparently widely different embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and dra-wings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is 1. In a device of the character described, the combination with a pulp box formed with a pulp receiving compartment at the top and a pulp containing compartment communicating with said upper compartment whereby the overflow of the pulp is delivered to the second-named compartment, a hopper communicating with the upper compartment and designed to discharge into the lower compartment, float means in said hopper link-connected to a valve in turn connected to the supply pump whereby on d the float being raised water is delivered auto thin the pulp tomatically by the pump thereof into the and facilitate the. flow lower compartment.

2. In a device of the character described,

thick pulp. This 60 ceiving hopper a pulp box provided with pulp intake means, a pulp receiving compartment and a pulp containing compartment, overflow means connecting said compartments, a refor the containing compartment and means connecting said hopper with the pulp receiving compartment, and valve operating means in the hopper adapted to be-operated on the contents of the hopper becoming too dense. i

In witness whereof I have hereunto setiny hand in the presence of ltwo witnesses FRANCIS JOSEPH XVALLACE. Witnesses:

VALENTINE MCNAMARA, DORA CRAWFORD.
