V UNITED STATES PATENT OFFICE;
PASCHAL r. EMORY, or SPRINGFIELD, MAssAoHUsETTs. I
S' TUFF- CHEST Fon PAPR-MLLS.
SPECIFICATIONtormng part oi: Lettrs Patent No. 654,961, dated uly 31, 1900. Application filed May mo'o; serial No. 16,562. (No model;)
To aZZ whom it may 0072067 Be it known that I, PASCHAL P. MORY, a citizen of the United States of America, re-
siding at Springfield, in the county of Hampden andState of Massachusettmhave in vented new and useful Improvements in StuiT-Chests for Paper-Mills, of which the following af specification.
This invention relates to stu lf chests for paper mills, the' object being to provide an improved bottom Construction for such chests whereby the very considerable waste of a part of the paper-pulp which has been subjected to the action of the agitatiug devices of the chest and is being discharged therefrom for other, and hence it is obvious that any means which will obviate more or less loss thereof when the pulp is transferred' from said chest' to said machine will prove of great advantage to the paper manufacturer, and such is the character of the improvements hereinbelow shown and described. i In the drawings formin g part of this specification, Figure lis a vertical sectional view of. the stuff-chest of a paper-mili containing my improvements, in which are illustrated the common pulp-agitating devices in side elevation, together with means for rotating the same. Fig. 2 is a perspective View of one of the bottom-sections of said chest and the central step-block thereof.
ed by the retainng-hoops 2.
The bottom of the chest consists of the main or lower one B, which is fixed to the inner wall of the body A of the chest, as shown, and of the superposed bottom-covering C, which is highest at a central point 3 within the chest and has a'surface inclining from said central-point to the inner wall of the body A, as shown.
The quantity of pulp and Water usually contained in the chest to be operated upon and there indicated by D has a weight of many tons, and hence the inner bottom construction herein shown, which while capable preferably of cylindrical form and surroundpipe E, located at the lowest point of said bottom C or at the junction of the border thereof and the lower end of the inner Wall of said body.
In emptying stuE-chests having flat botfitoms, such as is illustrated by said lower bottom-section B, a considerable quantity of the pulp is left thereon after said` emptying op eration which cannot run off through the said outlet, and that renders 'it necessary for a person to enter the chestand witha brush or similar implement remove the pulp which adheres to the bottom, as aforesaid. This method of completing the removal i of the pulp results in'sueh soiling thereof as unfits it for mixture with the first self-discharged mass thereof, and its Value isgreatly deteri orated and it is rendered unfit for use with that which has passed out of the chest, and the prevention of this injury to the pulp above referred to constitutes one of the said objects of this invention,
Said inner-bottom construction consists of a series of dovetail-shaped or tapering sections 4: (preferably of Wood) of graduallydecreasin g thickness from the narrower ends thereof to the wider one, as shown, whereby when laid upon said bottom B they form said inner bottom, which inclines, as shown, from the center of the chest to the inner wall thereof. Thethicker ends of said sections 4:
r have a circular step-block '5 fitted therebe- In the drawings, A is the body of the chest,.
tween as shown in Fig. 1, and in' said block is secured the shaft-stepfi. V
The pulpagitating devices of the chest consist of a Vertical shaft 7, having. its lower end supported in said step, and a suitable support for itsupper end, a driving-pulley and belt connection, as shown,or other suit able means for rotating said shaft and pulp agitating devices carried on said shaft, comprising the bar 8 and the ordinary depend ing pulp engaging and stirring elements 9 9. Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
In a paper-mili stufE-chest,a fixed lower bottom ,an inner bottom laid thereon on which the pulples and over which it, moves whendis' cha'gedf'om thechest, comprising a series of tapering 'sections of gradually deoreasing thiekness from the narrower to the wider end tions extendngfrom a entral point ox sad lower bottom` 130 the inner Wall of the chest thereby forming a bottom nclined from said ther eof laid on said. fixed bottqm, said. sec
