WATER-VALVE.

Specification of Letters Patent.

vPatented NOV. 1 2, 1918.

Application filed June 4,1917. Serial No. 172,769.

To all whom it may concern:

Be it known that I, THOMAS SoHooK, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake, State of Utah, have invented a new and useful Tater-Valve; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertains to make and use the same.

This invention has to do with water valves and is specifically a device for use on drinking fountains or similar devices.

The principal object is to provide in a device of this kind a plug valve that will automatically close itself when not in use and it aims further to provide a locking means for the valve. An additional object is to provide for use in conjunction with the valve a device whereby the valve may be used interchangeably as a drinking fountain or common Water drawing means.

It is further understood that the designed valve, as is shown in the drawing, will be of different designs for different places in which it will be used, it being further understood that it can be made of any desired size and of such material as to make it durable and effieient for the purpose for which it is intended, without thereby departing from the principle of the invention.

The structure disclosed may require some changes or alterations when put into practical use, but the right is claimed to make these, if contemplated by the dependent claims.

In the drawings Figure 1 is a plan View of the invention.

Fig. 2 is a longitudinal sectional view on the line 22 of Fig. l.

Fig. 3 is a transverse sectional View on the line 3-3 of Fig. 2.

Fig. 4: is a p rspective view of the plug valve proper.

Fig. 5 is a perspective View of the outer casing.

Fig. 6 is a transverse sectional view of the line 66 of Fig. 2.

In the drawings, 1 designates the base, having formed at its center a square recess 2, a round eye 3 penetrating through this base. Concentric with 2 and 3 are cylindrical segmental depressions 4 adapted to receive the springs 5. On this base 1 the plug valve 6 is designed to set in, the tubular member 7 passing through the eye 3 and the square lug 8 resting in the recess 2. It is intended that 7 shall connect with 6 by means of threads, the square end 8 which is integral with 6 being ta oped out to receive the threads 9 on pipe Pipe? communicates with a vertical bore 10 that ter niinates in a horizontal outlet 11. The plug 6 is surmounted with a threaded stud 12 integral with it. The outer casing 13 sits over the plug 6 and is designed to lit 6 snugly, but not so tight as to preclude its free movement around 6. Lugs 14 diametrically disposed and integral with the casing 13 are designed to sit in the segmental depressions 4t in such manner as to permit the springs 5 to bear against them and to keep the valve normally closed. At same height as the horizontal outlet. 11, the casing 13 has a boss 15 and through this boss 15 and the casing a threaded hole is formed. A tube 16 is screwed into this hole, but loosely enough to permit it to be turned by its handle 17 so that the bent end may project either up or down. A set screw 18, the end of which enters a slot 19 formed on the tube 16 at the same angle with its thread prevents 16 from being removed from the casing 13, but at the same time permits 16 to be moved Within certain prescribed limits. The cap 20 covering casing 13 at its top has a hole in its center through which the stud 12 projects, the nut 21 holding it firmly in place on top of the plug 6 with the gasket 22 intervening between it and the plug 6. The depending edge 23 of the cap is intended to encompass the upper edge of the casing 13 firmly, but at the same time not to interfere with the movement of 13 around the plug 6. Plugs 2.4 and 25 integral respectively with the base 1 and the casing 13, and having eyes for the reception of the lock 26 are intended as a locking means for the device when not in use. By setting up on the nut 21 to hold the cap 20 closely in contact with the gasket or washer 22, it is to be noted that the washer or gasket 22 spreads or bulges slightly overlying the marginal edge of the outer casing, which overlying part and together with the cap upward movement of the outer casing is prevented.

However, by the provision of this holding means the outer casing is not held so as to prevent or interfere with the movement of the casing around the plug.

In Fig. 2 a part 27 of a suitable stand is shown to which the valve is secured by the screws 28. Connection to a water supply may be made by any suitable means, preterably by a conventional union. As an aid to securing the valve, on the stand 27 is a flange nut 29 which threads over the pipe 7 and compresses the resilient washer 30, against 27, 30 being of small enough diameter to sit in the flange portion 29.

The device having been set up substantially as described, it is intended to operate as follows:

The plug 6 is stationary and is connected to an available water supply. The casing 13 has free movement over 6 to the limit of the compression of the springs 5 within the depressions 1, and at a certain part of this movement the tube 16 will register with the outlet 11,-whereupon water will flow from the supply means through th pipe 7' up through the vertical bore 10 through the I horizontal outlet 11 and issue from the bent end of the tube 16. If the bent end of 16 is turned up, the drinking mountain function is performed; if the bent end is turned down, the device performs the function of a common spigot. It is necessary that the outer casing 13 be held in the position where 16 will register with the outlet 11 for water to flow, for otherwise the springs 5 would return 13 to'the point where 16 and 11 are not in registration and the water would be cut off. The lugs 14, by coming in contact with the ends of the depressions 4 remote from the ends against which the springs 5 bear, limit the movement of the casing 13 in the turned-off position, the lugs 25 and 24 being then in close proximity the valve may be then locked in its turned-oil position by the lock 26. w

The plug 6 and its outer casing 13 are designed to be conical in shape, it being held that in constant use the friction of '6 and 13 will eventually become worn, and the two being conical shape can be readily tightened with-the nut 21 and a better bearing surface can be obtained between the two, it they are conical rather than cylindrical in shape.

What is claimed is:

1. In a valve of the kind described, a conical stationary plug having an intake and outlet, a base on which said plug is mounted, concentric segmental depresslons in said base, a conical outer casing adapted to fit over the plug, means at the top of the plug for securing the outer casing against longitudinal movement with respect to the plug, diametrically disposed lugs on the outer casing adapted to slide in the segmental depressions of the base, and springs resting in these segmental depressions and adapted to press against said lugs to keep the valve normally closed.

2. In a water valve, a base, a supply pipe passing therethrough, said base having a central depression concentric with the supply pipe, conical stationary plug having a reduced part on its lower end engaging said central depression and threaded to the supply pipe and having a longitudinally extending central passage provided with a lateral port at its upper end and communicating with the supply pipe, said base having segmental diametrically opposed recesses concentric with the depression, a conical outer casing fitting over the plug and having diametrically opposed lugs on its lower end sliding in said segmental recesses, springs resting in the recesses, one engaging between one end of each recess and one of the lugs, means on the upper end of the plug to secure the outer casing against upward movement, and an outlet tubecarried by the outer casing and adapted to register with the lateral part of the passage in the plug.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS SCIIOCK.
