ALARM DEVICE FOR GASOLENE-TANKS.

Specification of Letters Patent.

Patented Sept. 2, 1913..

Application filed March 7, 1912. Serial No. 682,148.

To allwhom it may concern Be it known that I, Jon C. S'roNE, a citizen of the United States, residing at Tipton, in the county of Tipton and State of Indiana, have invented certain new and useful Improvements in Alarm Devices for Gasolene Tanks, of which the following is a specification.

This. invention relates to alarm devices for gasolene tanks or reservoirs, and has for its primary object to provide a simple, efficient and positively acting device of this character which is particularly designed for use in connection with the gasolene tank of a motor driven vehicle.

Another object of the invention resides in the provision of a tubular casing arranged within the gasolene tank, a conducting pipe connected thereto, said casing having spaced outlet ports for the fluid and a rotary valve member arranged within said casing and having a port to aline with one of the outlet ports of the casing, whereby the gasolene is maintained within the tank at a fixed depth.

Another and more specific object of the invention resides in the provision of a tubular casing having upper and lower outlet ports, a rotary valve member provided with a single port to aline with one of the ports in said casing, and a reticulated fabric surrounding said casing to prevent sediment conveyed in the fluid from passing through said ports.

v A still further object of the invention is to provide an alarm device for the above purpose, which is simple in construction, may be economically manufactured and is also eflicient and positive in action to notify the operator that the supply of gasolene is almost exhausted.

With the above and other objects in view, my invention consists in the construction, combination and arrangement of the several parts, all as will hereinafter be more fully escribed.

Figure 1 is a section through the gasolene tank having my improved alarm device therein, the reticulated guard being partly broken away. Fig. 2 is a vertical section thereof. Fig. 3 is a perspective view of the alarm device.

Referring in detail to the drawings, 5 designates a tank or reservoir which may be of rectangular or cylindrical form and is preferably, though not necessarily, con structed of sheet metal. The bottom wall of this tank is provided with an opening, through which a nipple extension 8 formed upon a base plate 7 projects. To one end of this nipple a conducting hose or pipe 9 is threaded or otherwise suitably connected. This base plate is securely riveted to the bottom of the tank or reservoir as shown and is provided with a central tubular boss 10, which is interior threaded to receive the lower .end of a vertically disposed tubular casing 11; Upon the upper end of this casing, an annular head 12 is integrally formed, and said casing is also provided with a short extension 13 projecting above said head. The casin 11 has a port 14 in its wall beneath the liead 12, and adjacent to the lower end of said tubular casing a second port 15 is provided. A bushing 16 is disposed through an opening provided in the top wall of the tank or reservoir 5 and a tubular valve stem or red 17 is disposed through said bushin and has its lower end extending Within the tubular valve casing 11. This lower end portion of the rotary valve rod 17 is provided with screw threads 18 which engage the threads 19'providedupon the inner wall of the casing 11 between the upper and lower ports 14 and 15 respectively. The tubular valve stem 17 is provided with a single port 18, and upon the upper end of this stem above the supply tank, a circular head piece 19 is formed, the periphery of which is preferably milled or knurled, whereby the same may be readily turned and the valve stem quickly rotated to thread the same downwardly or upwardly within the casing 11. By means of this arrangement of parts, it will be readily understood that when the valve stem 17 is screwed downwardly Within the casing 11, and the port 18 of said stem brought into register with the upper port 14 in the valve casing, while the level of the gasolene' or other combustible fluid: within the tank is above these ports, the fluid willcontinue to flow outwardly'through the valve and into the conducting pipe 9. When the gasolene reaches these registering ports, the flow ofthe gasolene from the tank gradually lessens until it entirely ceases. The operator of the 7 vehicle is thus warned that the supply of .gasolene is almost exhausted. If he is within convenient reach of a supply station where an additional supply of gasolene may .be obtained, the operator will rotate the tubular valve stem or rod 17 so as to move the same upwardly through the valve casing 11 until the lower end of said stem is disposed above the lower port 15 of the valve casing, as shown in Fig. 2 of the drawing. The flow of the gasolene from the tank now 'continues so that the machine may be again operated until the suppl station is reached.

In the upper end 0 the tubular valve stem 17 a nipple 20 is threaded, said nipple being provided with a longitudinal bore 21 whereby the air may be admitted to the interior of the stem. The, upper end of this nipple is threaded to receive a suitable closure cap 22 which covers the upper end of-the bore 21 and prevents dirt or other foreign matter from entering the same.

Frequently the gasolene will contain a considerable amount of sedimentary matter,

and in order to prevent the same from entering. the conducting pipe through the ports of the valve casing, I provide a cylindrically formed reticulated guard 28, the upper and lower ends of said guard being suitably secured to the annular head 12 and the base plate 7 respectively as shown in Figs. 1 and 2. This guard is of fine mesh wire so that foreign materials contained in the gasolene are prevented from entering through the same and finding their way into the conducting pipe 9, whereby the proper combustion of the fluid is assured.

By means of the construction hereinbefore set forth the lead pipe and carbureter may-be cleaned out. The ports being closed and the cap 22 removed, the nipple of a tire pump may be attached to the nipple 20 and air forced through the. pipe and carbureter from the pump; Another advantage of this invention is that by reason of its construction gasolene may be shut off at the top of the tank instead of at the bottom, which is in the machine.

From the foregoing, it is believed that the construction and manner of operation of my alarm device will be fully understood. Thr various parts thereof may be easily and quickly arranged within gasolene tanks or reservoirs now in use upon motor driven vehicles Without requiring any material change in their construction, it being simin practical operation.

of the invention, it will be obvious that the same can be inexpensively manufactured, and Is also extremely While I have shown the actual construetion and arrangement of the various parts,

it-will be understood that the invention is susceptible of considerable modification without departing from the essential features or sacrificing any of the advantages thereof.

durable, and eificient What I claim as new and desire to secure by U. S. Letters-Patent, is

l. The combination with a tank or reservoir, of a vertically disposed tubular valve casing opening through the bottom of the reservoir, and .a vertically disposed. tubular valve stem threaded at its lower end within said casing, the upper end of said valve stem being rotatably disposed through the upper wall of the reservo1r,'said casing having upper and lower discharge ports adapted to be closed by said valve stem, the valve stem being formed with a port adapted for registration with-the first mentioned discharge port, at-which time the second mentioned port is closed, an outward movement of the valve causing the first mentioned port to be; closed and the second mentioned port to be opened.

' 2. The combination with a tank, of a vertically disposed valve casing opening through. the bottom of said tank, a tubular valve stem projecting into said valve casing and open at its lower end, the. valve casing being formed with an upper discharge port and a lower discharge port, the valve stem being formed with a port adapted to register with the first mentioned discharge port, at

which time the lower discharge port is' closed, and means for moving the valve stem outwardly, whereby the first mentioned discharge port is closed and the second mentioned discharge port opened.

3. The combination with a reservoir, of a vertical tubular casing within said reservoir, said casing projecting through an opening in the bottom thereof, a tubular valve stem threaded at its lower end within said casing and projecting through an opening in the top of the reservoir, a milled head formed upon the outer end of said valve stem, whereby the same may be rotated, said casing being formed with upperv and lower discharge'ports, the valve stem being formed with a port adapted to register with said 1,07%,371 iln testimony whereof I affix my signature 1n presence of two wltnesses.
