STOPCOCK FOR GAS MAINS.

1 Application i filed January This invention (has general relation to fluid pressure systems, but has particular relation tomeans'for'introducing into gas or otherfiuid while being conducted through a pipe, such as a gas main, means or material to prevent the moisture contained in the gas or fluid freezing, and thereby stopping or retarding its flow through or to the proper service pipes.

The principal object of the invention is to furnish a very simple, inexpensive yet highly efficient stop cock for. gas mains and the like of such construction, arrangement and combination of its parts to afford easy and efficient means for turning on or off the fluid or gas, when desired, and when it is turned off, for supplying a container associated with said cock and the main pipe, with a quantity of alcohol or other volatile and anti-freezing material to be subjected to the gas when again turned on.

A further ob ect is, to provide means for i preventing access to said container and its contents, by an unauthorized person, or except, when the gas is turned off.

Other objects and advantages of the in' vention will be disclosed. in the following description and explanation, which will be more readily understood when read in conjunction with the accompanying drawing in which an embodiment of the invention is illustrated, it being understood that changes and modifications therein may be resorted tov without departing from the spirit of the invention, so long as they fall within the scope of the appended claims which form a part hereof.

Referring now to the drawing:

Figure 1 is a plan view of this stop cock and a portion of the gas'main, and

Figure 2 is a longitudinal sectional view taken online 2, 2 of Figure 1, looking in the direction indicated by the arrows.

In the drawing, the gas mainor a part thereof, is shown and designated by the separate sections 3, and 4, thereof, between which sections is mounted a depending container, 5, which is preferably rectangular in shape, and may be of any suitable size and material. This container has at the upper portion of one of its ends an internally screw threaded boss, 6, and at its opposite end, a short pipe extension, 7, both of which elements communicate with the container 5. The member 7 is provided with an extension 30, 1826. SeriaI No. 84,932.

"8, which is internally screw threaded and and held in place by means of an annular washer, 12, and a nut, 13,the latter being in screw'engagement with the valve 10.

Rigidly mountedon the upper portion of the valve 10, is a gu'ard plate, 14, which is provided with diametrically disposed cutaway portions, 15, as shown in Fig. 1 of the drawing. Above the plate 14, the valve 10, has fixed thereon a nut, 16, to be used for turning the same. In the top of the container 5, near the member 7, is provided an opening 17, for

the supply of alcohol, 18, to the container,

which opening may be closed by means of a,

plug, 19, or otherwise.

From the foregoing, and by reference to the drawing, it will be'readily understood and clearly seen that assuming the parts are in the position shown in Fig. 2, of the drawing, the valve 10, will be open so as to allow the free passage of gas through the sections 3 and 4c of the main, as indicated by the arrows, thus allowing the gas to be subjected to the alcohol, 18, of the container and thus prevent freezing of the moisture contained by the gas. By turning the valve, say onequarter of the way around, it is obvious that the flow of gas will be shut OE and that at the same time the plug or closure 19, will be exposed through one of the cut-away recesses 15, in the guard plate 14, so as to permit of the removal or insertion of said plug.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is-' '1. In a device of the class described, the combination ofa gas main having two fixed pipe sections spaced apart, a container located between said pipe sections and in communication therewith, said container having a chamber out of line with the direct path of travel of the gas from one of said sections to the other section but exposed to said path, a removable closure located in the upper part of the containernear the adjacent end. of one of said pipe sect-ions, a sh'ut-oflf valve rotatably mounted in the path of travel of the gas. near said closure and a guard plate fixed on said valve and having a part extended over said closure when the said valve occupies an open position.

2. In a device of the class described the combination of a gas; nl ain-lfiav-ingtwo pipe sections spaced apart. a container located between said pipe sections and in communication therewith, said container depending in part from said sections, a removable closure located in the upper part of the container near the adjacent end of one of said pipe sections, a shut-off valve iotatably mounted in the path of travel of the gas near said closure, and a guard plate fined 'on' said valve and having a part extended over said closure when the said valve occupies an open position, and cutaway on each side of the valve to permit the closure to be removed when the valve is turned to a closed position in either direction.
