VALVE.

' Specificationy of Letters Patent.

Patented Sept, 1916.

Application led April 10, 1915. Serial No. 20,549.

To all who/m, t may concern:

Be it known that I, FRANK O. SHERIDAN, residing at Covington, Kenton county, State oi' Kentucky, have' invented certain new and useful Improvements in Valves, ot' which the following is a clear', fulhaud exact de scription, attentio-n being called to the drawing which accompaniesy this applicationy and forms a part thereof. y

rIhis invention concerns lvalves used for the purpose ofcontrolling passage oi liquid matter through conduit pipes.' It relates more particularly to such` valves which are used in connection with the service-pipes, mains andjbranchesthereof, ot water-supply systems.

The object of the invention is to construct such valves in a manner that they may be readily operated and maintained in operative condition7 that they move `freely and that they are not subject to the eii'ects of obstructions.

The invention consists of the particular construction whereby this object is obtained and as the same is described hereinafter and pointed out in the claim.

In the drawing referred to in said description, Figure 1. is a vertical cross-section ci vsuch a valve and shown in connection with a hydrant or tire-plug. Fig. 2. in a similar View shows the valve as used in connection with a main or line-pipe. Fig. 3. is a horizontal section ot a certain part shown in Fig. 2 and on a line indicated at Si?) in said figure.

The valve indicated at A, occupies a posi tion above a horizontal partition 6 which separates two chambers 7 and 8 from each other. These chambers of which the irst constitutes the intake chamber, are contained within a housing B and are outwardly open and the housing at its open ends is arranged to permit its interposition and connection to the parts of the water conduit where the valve is to be used.

Valve A is substantially like an inverted cup and telescopes a tubular neck 9 on which it is mounted to move with a sliding lit. Neck 9 projects upwardly from an opening in partition 6, which opening forms an outlet from intake chamber 7 This opening is screw-threaded and neck 9 is removably seated therein. When valve A is in a position as shown in Fig. 1, no water can pass.

IVhen raised to a position as shown in Fig. 2, water passes from chamber 7 into chamber 8 through ports 11 which are provided in sufficient number and size in the side of neck 9. The seat ot the valve is on the outside of neck 9 and a close tit is obtained by means of packing 12 occupying an annular recess in the edge of the valve and held therein by a ring 13.

In the device shown in Fig. 1, the valve is used :tor the purpose of controlling water supplied from a branch pipe to a lire-plug 14. The valve housing at one of its openends is therefore provided with a socket 15 to permit connection to said branch pipe and formation of a calking joint thereat. At the other open end of the housing a flange 16 is provided to permit connection to the hollow column which forms the tireplug. Nipples 17 are provided on said plug where hose connection may be made in the usual way after caps 18 have been removed.

In the device shown in Fig. 2, the valve is used to control passage through a pipe line and accordingly the valve housing at both ends is arranged to permit insertion into such a line. A socket 19 to permit connection and formation of a calking oint is provided or the purpose at each end of the housing. In this case the latter is further subdivided by a vertical partition 21, so that direct passage oi' water through the housing is prevented and limited to ported neck 9, where it is subject to control by valve A. When this latter is open, water from intake chamber 7 passes into chamber 8 and from there by means of a bypass E22 it is deflected within the housing and turned back into the pipe line, in which it passes on.

VThe valve may be manipulated by any suitable means. In each case 'it is connected to a valve stem 23. In the case of the tireplug, the upper end of this stem carries a screw thread which is fitted into an operating nut 2li, held against movement in axial direction in the manner shown. rlhe upper end of the nut is square to permit engagement by a key or wrench. Below its screwthreaded portion, the stem has a square portion 25 fitted to a guide plate 2G. `When nut 24 is turned, stem 23 will move axially, opening or closing the valve according to direction of rotation. No novelty is claimed for the construction of this movement.

In the form shown in Fig. 2, the valve stern is threaded and seated in a bonnet 27 connected to housing B so as to close the open end of chamber 8. The lower end of the stem has a shouldeil which is engaged by a cap 28 secured to valve A and whereby this latter is connected to the stem. The upper end of the stem is square to permit engagement by a key for manipulation. When the stem is rotated it moves up or down in the bonnet, according to direction of rotation and moves the valve accordingly.

29 is a stuiiing box and 3l is a casing which extends to the surface to permit ac cess to the valve stem from above.

Considering the particular purpose of these valves and their position in the ground below the surface,- it is essential that access to the vital parts for their repair or renewal may be had in the most ready manner without taking up the housings and disturbing the pipe lines. As will be seen the construction is such that this is'not' required and access from above is rendered possible for the purpose of re-packing the valve or renewing the neck upon which it is seated.

Having described my invention, I claim as new:

In valve-construction designed for use under ground, the combination of a housing which is open at one end to form an inlet and is subdivided by an integral horizontal partition to form an inlet chamber between said partition and the inlet and a discharge chamber above said partition, a detachably connected bonnet to close said discharge chamber, an opening in the partition mentioned, a neck seated in this opening with a screw-connection and projecting upwardly from the partition, port-openings provided in this neck which extend from its upper edge downwardly and terminate some distance above the partition, a cup-shaped valve fitted around the outside of said neck and provided with an inturned recess around its lower edge, packing in this recess, a ring to hold this packing in place and to maintain it in fitting contact with the outside of the neck against which the valve is seated and a stem projecting upwardly from said valve and extending through the bonnet mentioned for manipulation from above to adjust this valve with a sliding movement to and from the partition mentioned and between said partition and the upper edge of the neck.

In testimony whereof, I hereunto aiix my signature in the presence of two witnesses.
