LOCKED HOUSING FOR VALVES.

Application filed September 9, 1922. Serial No. 587,161.

T all whom it may concern:

Be it known that 1, JAMES W. Moons, a citizen of the United States, residing at Moult-rieville, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Locked Housings for Valves, of which the following is a specification, reference being to provide a device of had to the accompanying drawings. 1 I

It is the purpose of the present invention this kind applicable on pipe lines (through which any fluid may I pass) in general use, either under or above ground, or indoors or outdoors, in fact regardless of where the pipe liiiemay be located, for the purpose of, housing various valves, spigots or the like to prevent tampering therewith by unauthorized persons, especially when valves are located in public places.

Another purpose 'is to provide a housing including a lock, which may house the entire valve, or may house the hand wheel of the valve, the housing to be engaged with the valve casing immediately below the stuffing box, thereby preventing access to the wheel, and also preventing the valve from being tampered with. Obviously the] locked housing may be constructed any size, for housing any size of valve casing or hand wheel.

Still another purpose is to provide a locked housing constructed of any'suitable.

sheet metal, preferable thin sheet steel, light but necessarily strong, durable and rigid, the housing in the present instance comprising a base section and two hingedly supporte sections, the base section to. engage under the valve, whiie the two hingedly supported sections may swing toward eachother and over the valve casing, so thatin connection with locking means, tampering with the valve or any part thereof by unauthorized persons may be prevented.

A further purpose is the provision of a device of this character, wherein the two hingedly supported .sections are each constructs provide three sides and a top end, one of the sides having extension flanges overlying and secured to the other sides to form the section, said flanges being extended at one end of the section, for the purpose of pivotally riveting the section on the base section. W hen the sections are opened, they of a single piece of sheet metal, preferably thin sheet steel, formed so as to may assume approximately a 45 angle with relation to the base section, to permit access to the valve.

It is to be understood that the particulars herein given are in no way limitative and that while still keeping within the scope inafter set forth, shown in the drawings and claimed.

Figure 6 is a horizontal sectional view on line 6-'6 of Figure-4c;

Figure 7 is a perspective view of the locked housing detached from the valve, and showing the two hingedl supported sections open; Y

Figure 8 is a detail view of the blank from which one of the hingedly supported sections is constructed, showing the parts of the blank partly bent;

Figure 9 is a detail view of the blank from which the base section is constructed, showing certain parts thereof bent to form the section; 1

Referring to the drawings, 1 designates the pipe line, through which any suitable fluid may pass. This pipe line may be underfor over ground, or indoors or outdoors, or any other suitable location.

Carriedby the pipe line is a conventional form of gate valve 2, which carries the usual hand wheel 3, for operating the valve proper (not shown).

The locked housing comprises a base section 4 and the two hingedly supported sections 5. The base sections comprises a bottom 6 the sides and ends '3 and 8 integraliy in the locked housing for housing an ens a perspective View of the- 75 of Figure 1, showing the two hingedly supconnected to the bottom, and-. carried integrally b the side pieces are flaps 9, which overlie and are riveted or otherwise secured at 10'to the end pieces of the base section. a I The end pieces 8 have semi-circular openings 11, which engage the pipe line.

Each hingedly supported section com As previously stated the sides 13 are in-.

tegral with the top end piece, therefore when the top end piece is bent, to assume a position at right angles to the broad side, the side pieces 13 are bent to assume parallelism with each other, and while so dis-.

posed the flanges 15 are bent to overlie the side pieces 13 and are riveted, .spot welded,

"brazed orotherwise fastened thereto, so. as

to insure a rigid and secure housing section, for protecting and locking the valve against being tampered with by unauthorized persons.

The lower corners of the adjacent edges of the side pieces 13 of the hingedly supported sections are cut away, causing to be formed quarter circular portions, which engage with the pipe line, and when the two hingedlyisupported sections are closed the quarter circular portions and the semicircular openings cause circular openings to be formed in'the housingfor the reception of the pipeline, as shown inFigure 1.

In Figures 1, 2 and 3 the two hingedly supported sections are provided with a padlock 17, for the purpose of locking the two sections together, thereby preventing access to the'valve or the handle wheel.

. However in certain other figures where the complete housing is illustrated, a suitable spring lock is' employed, as indicated at 18, which will lock when the two sides are pressed together. It may be that the gprin lock is more essential and more useul t an the padlock, as the parts lock quicker and with less trouble than with the padlock, since a person would not be required to place the hasp over a keeper, as when a padlock is used.

In certain of the figures where the housing is shown as up lied to a valve to merely house the hand w eel it will be noted that the circular opening in one side of the houssu tcases ing is formed around the casing of the valve, at a point immedia ely below the stufiing box, for the purpos bf housing hand wheel and preventing access thereto,

and flikewise avoiding tampering with. the valve by an unauthorized person.

his 0 be noted that the openings for the r9ce tion of the pipe line are formed in opposite sides of the housing, and obviously when the housing is a plied to'a spigot, or to a globe valve or t e like, so that the housing may engage the casing of the valve immediately below the stuffing box, one of said openings is left open.

However the opening is not sufiicient to per-.

mit access to the hand wheel for the purpose of operating the same. Under conditions of this kind the housing may have only one opening to' avoid insertion of an instrument to operate the valve.' Though the openings are formed in opposite sides of the housing, it is possible to construct a housing with an opening in one side, so asto permit said opening to engage about the casing of a valve below the stuiiing box. In.

this case the housing will be specially constructed, while other housings may be constructed with openings in opposite sides, in

which case this latter housing can be used in connection with pipe lines wherein the valve is entirely surrounded by the housing, or in connection with pipe lines wherein the housing may be connected to the valve casing immediately below the stuiiing box, for the purpose of housing the hand wheel alone, instead of including the valve casing.

The hingedly supported sections adjacent where they are hingedly mounted-upon the base section having abutment edges 19,

which engage opposed'sides of the base sec-' tion to limit the hingedly supported sections in open positions, said hingedly supported sections extending laterally and upwardly.
