UNITED STATES PATENT OFFICE.
VALVE FOB PAPER-PULP CONDUITS.
Specification of Letters Patent.
Patented Feb. 28, 19Q9.
Application filed June 18, 1908. Serial No. 438,262.
To all whom it may concern:
Be it known that I, GEORGE W.K1MBALL, a citizen of the United States of America, and resident of Springfield, in the county of Hampd'en and State of Massachusetts, have invented certain new and useful Improvements in Valves for Paper-Pulp Conduits, of which the following is a full, clear, and exact description.
This invention relates to an improved valve and valve casing comprised in a three way coupling section for connection with a paper pulp supplying conduit and branch conduits for conveying the stock, according as its course is controlled by the ositioning of the valve gate, through eit er of the branch conduits for delivery for use in paper machiner in different parts of the mill.
In the orm of valve bodies heretofore used in the situation here contemplated the valve was so journaled within the casing therefor that a part of the casing carrying one of the branch ways required to be bodily disconnected and removed in order to get the valve out for the purpose of replacing it with a new gate, as necessitated by the pulp and foreign matter cutting out and wearing the valve especially at its journaled edge, and as otherwise necessitated, as, for instance, by the lodging within the valve of hard obstructing substances not always accessible through the hand hole.
The object of this invention is to rovide a construction of gate valve and a va ve casing therefor comprising branch ways whereby b the removal of only a com aratively small we 1 constituting sectionof t e casin the valve may be directly bodily remove to permit the removal of obstructions or the renewal of the valve.
and arrangement of parts and the constructions of parts substantially as hereinafter described in conjunction with the accompanying drawings and set forth in the claims.
11 the drawings :'Figure 1 is a plan view of the coupling section to be comprised in its connection between a pulp supplying conduit and two differently directed pulp deliveri; conduits; Fig. 2 is a sectional view as ta en on the plane of the axes of the branched ways. Fig. 3 is a (pers ective view of the coupling section an va ve casing with appurtenances thereof removed and indicating the convenient removability of the valve gate; Fig. 4 is a perspective view representin the removable appurtenances of the va ve casing; Fig. 5 is a view in substance like Fig. 2, but showing branched ways arranged at an acute, instead of a right, angle; Fig. 6 is a plan view and projoctedside view of the valve operating handle lever.
Similar characters of reference indicate corres ending parts in all of the views.
In t e draw1ngs,-A represents the valve casing comprising a cou lin section having three ways therethroug t e one a being, for instance, understood as to have coupling connection with a pul supplying pipe of large diameter, while the ways I) and d are for coupling connections with differently directed pulp delivery pipes of large diameter. The casin A 1s constructed with an aperture ff throug the crotch at the junction of two 0 the angularly arranged ways, said aperture being arranged at right angles to t e axial lines of the ways, and it has a len th approximately that of the diameter of t e opening within or through the valve casing. The Wall of easing A, is provided at said crotch with a cut-away part forming two walls arranged at right angles to one another in the form of an L. The casing has in its walls adjacent the ends of. said apertures alined partially cylindrical recesses 57 .9, best shown in Fig. 3. B represents the valve ate carried by and extended radially beyond the side of the shaft D which is inte- 1gral or unitary therewith, and the valve may e removably positioned in the valve casing through-said narrow crotch aperture to bring it to its operative position and to ave the portions '5, i of the shaft, which are op- 1gositely endwise beyond the valve ate,
tting in the said partially cylindrica recesses g. G represents a casing'section or segment for removably closing the said crotch aperture, the same having a partially cylindrical recess g along its inner side for the accommodation of the gate valve shaft, and said section comprises angularly extended cheeks or flanges to closely fit against the finished faces o the valve casing adjacent and outside of the crotch aperture and to be confined in place as a part of the casing by the screws or bolts m.
F and F represent caps removably secured on opposite sides of the valve casing near its crotch, being secured by the screws or bolts 0, and portions of these caps extend, shelf-like, across the space within the crotch in contact with and covering opposite ends yond the cap 'and having rigidly connected therewith thioperatirig handle levi' 'lfi b. The vaisa aiaa teih ia' 1d 'edfi ,ction G, andhave Manifestly, by posltippipg the nalve as shown in F1 2, the coiii'seof the pulp will,

The removability and re lacerii'ent of the valve is apparent fromjthe rawings and the description in conjunction therewith already given. I I
The caps F and F in addition to constituting bearings for the journals of the gate valve shaft also form closures against leakage of pulp along the journals,'w representing compressible packings for the caps, while packings a: are provided between the ap roximate faces of the flanges of section 8 and the valve casing proper.
I claim 1. A valve casing, comprising a couplingsection, having three ways therethrough, and-constructed with an aperture through the crotch at the junction of two of the angularly arranged ways having approximately the length of the diameter of said we. 5, a shaft, and a valve-gate, carried b an extended beyond the side of the sha t, and removably positioned within the valve casing through said narrow crotch aperture, a detachable section, closing the said crotch aperture, and caps, removably secured on crotch and having alined journal openings opposite sides of the valve-casing near its for extremities of the shaft which are extended beyond the opposite edges of the V three ways therethrough, Ease cbilst'i u-hted w1th *a' stra1ght narrow aperture through the crotch at the junction "section; having the angularly arranged ways, "having approximately the length of the diainetere said ways, and said iiaisiiig hawin g giltits gwallsg adjacent the ends of sald aperture, alined partially cylmdrlcal recesses,
. V ally, cglmdrical recesses, a caslng section remove.
1y closing the said crotch a erture, and having a artially cylindrica recess along its inner si e for the accommodation of the gate valve shaft, detachable means'for the confinement of the said casing section on the main body of the valve casing, caps removably secured on opposite sides of the valve casing near its crotch extending across the opposite ends of said removable casing section and having alined journal openings for the extremities of the valve shaft, one of which extremities extends through and beyond the cap and has an operatlng handle ever.
3. A valve casing having three ways, a valve gate operating in the space at the uncture 0 said ways, an operatmg lever for said valve gate, and a swinging dog on the casing having its free end adapted to abut said lever on either of its opposite sides to sustain the same in different positions.
4. A valve casing having three ways, a valve gate operating in the space at the uncture 0 said ways, an operating lever for said valve gate, an abutment carried by said lever at a point intermediate of its length, and a dog pivoted at one end to said casing, and having its opposite end free and adapted to enga e the o positesides of said abutment to ho (1 said ever in difierent ositions.
