Patented Apr. 22, 1930 UNITED STATES PATENT 'oFFicE HAMILTON C. CHASE, 013 LOS ANGELES, CALIFORITIA, ASSIG-NOR OF ONE-FOURTH TO TOBIAS WEBER AN D ONE-FOURTH TO HAROLD ROE, (11? L ANGELES, CALIFORNIA VALVE Application filed October 21, 1926. Serial No. 143,039.

This invention relates to a valve structure comprising a hollow shell slidably mounted within a body. The present invention per-' tains more particularly to a split shell struc 5 ture arranged so that pressure of fiuidtherei to provide a valve structure of the character described which may be operable at will and may be arranged to do'away with the neoessity of packing. These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Fig. l is an axial section through a tank faucet embodying myimproved valve; Fig. 2 is a section as seen on the line 22 of Fig. 1;

and Fig. 3 is a section transverse to that of Fig. 1 taken through the valve operating housing.

Referring more particularly to Fig. 1, a valve body is indicated by 5. This body is substantially cylindricalin form and has a spout 6 depending therefrom at an angle. 0n the spout is a book 7 for engagement with the bail of a bucket or like receptacle. The bore of the body is substantially cylindrical, there being a port 8 at one end for communication -of the spout and the bore. The diameter of the bore is reduced at one end and the body is internally threaded as indicated by 9. This is for the purpose of connecting a faucet to a source of supply of liquid, such as a tank. The opposite end of the body is internally threaded to receive a closure plug 10. At the top of the body and opposite to the spout is a slot 11 to accommodate a pin forming a portion of the operating mechanism.

Snugly fitted within the bore of the body so as to be slidable longitudinally is a split shell 12. This shell is of such length that it may be moved to abut the end 9- of the body and will uncover the port 8. It is split longitudinally as indicated by 13 and is provided with an inwardlyextending boss 14 providing a socket for the operating pin. It will be noted that the ends of the shells are bevelled.

This aids in a cleaning action on the wall against which the shell fits.

Seated on the body 5 is a housing 15 for the operatin mechanism. The housing is in plan in the Iorm of a sector, there being a post 16 pivotally mounted in the body at one end. This post is disposed in a socket within the body and mounted below the post is a compression spring 17. The construction is such that the post 16 may not only ber-otated, but may be moved axially. The upper end of the post which projects beyond the body and is disposed within a cup-like portion is squared or flattened upon one side to provide for engagement by a key for turning'the post. Fixed to the post is an operating arm 19 slotted at one end to embrace an operating pin 20 disposed in socket 14. Obviously, by turning the post 16, the arm 19 may be swung and the shell 12 moved within the body through the intermediate section of pin 20. Depending from the upper wall of the housing is a'lug :21 arranged to engage in the slot in the end of arm 19. This'lug is disposed so that when the arm 19 is in its valve closing position, the lug will hold the arm 19 from being swung, unless the arm is moved downwardly to clear the lug. In order to swing the valve to open position it is necessary to engage the post 16, move the latter downwardly to clear the lug. In order to swing the arm 19 to the opposite side of the housing. I

It will be noted that the fluid to be controlled passes through the supply end of the body into the bore of the shell. The pres sure of the fluid upon the shell causes the latter to expand and snugly fit against the wall of the body. No packing is required. It is obvious that the invention may be embodied in other types of valves.

lVhat I claim is:

1. In a valve, a body having a bore with an inlet for the supply of fluid thereto at one end and a discharge port in the side wall of said bore remote from said inlet, an open ended split shell having a chamber freely communicating with said inlet at one of its ends, said shell being disposed intermediate said inlet and discharge port for sliding 00 movement in said bore with the other end of said shell disposed to traverse said port so as to be moved to cover and uncover said port.

2. In a valve, a body having a cylindrical bore closed at one end and open at the other end and adapt-ed to be connected at said other end to a source of fluid supply, a discharge port in the Wall of said bore, an open ended split shell having a passage extending therethrough with one end facing the open end of said body and the other end disposed at said port, said shell being disposed for sliding movement in said bore with said other end disposed to be moved to cover and uncover said port.

- 3. In a valve, a body having a cylindrical bore closed at one end and open at the other end for connection to a source of fluid supply, a discharge port in the wall of said bore, an open ended split shell having a passage exd ng the ethro g with one n facing the open end of said body and the other end disposed at said port, said shell being disposed for sliding movement in said bore with said other end disposed to be moved to cover and uncover said, port, a slot in the side wall of said body, and operating means accommodated in said SlOVand engaged with said hell fo operating th e 4:. In a valve, a body having a bore with an inlet for the supply of fiuidthereto at one a and a dischar e port in the side wall of said bore remotefrorn said inlet, an open ended split shell having a passage extending therethrough frfiely communicating with said i l t a one of it e ds, ai el ng posed for sliding movement in said body with the other end of said shell disposed to traverse said port sov as to be moved to cover and un- CQVQI said port, there being a slot in said body sealed by a d he l, a d, p r i g means extending through said slot and engaged with said shell for sliding the latter.
