TANK.

Application filed March 9, 1925. Serial No. 18,950!

This invention relates to tanks for use in distributing and dispensing volatile liquids, particularly gasoline, and is directed to the provision of a tank of an improved construction adapted to be mounted upon the chassis of an automobile for use in distributing gasoline to a multiplicity of service stations. More particularly the invention relates to a tank of the type in which the body is subdivided into a plurality of separate compartments such that the gasoline may be withdrawn from any selected one of the said compartments without afiecting in any way the supply of the others. By so subdividing the entire amount of gasoline carried by the vehicle into a plurality of separate supplies in the several compartments, the element of danger incident to conveying such an inflammable fluid, more particularly in crowded city streets, is greatly reduced.

In accordance with the invention, the plates from which the tank is made are shaped to form a trough or elongated sump running the full length of the tank and under the entire line of tank compartments and means are provided whereby the contents of any compartment may be discharged into this trough through which they flow to suitable outlet devices.

In the preferred embodiment of the inventionthe plates which are employed for dividing the tank into the several separate compartments are extended below the body of the tank formed by what is known as a wrapper sheet and these extensions of the division plates are employed to support the tank as a whole and stifi'en its structure. When this construction is employed in a tank having the lengthwise trough above referred to and valved outlets to the trough from all of the several compartments, the extensions of the division plates are provided with holes through which the liquid may flow from one section, of the trough to another.

The trough referred to is preferably provided by pressing the Wrapper sheet to the shape required for providing the trough, and then placing a (plate over the top of the trough and wel 'ng its lateral edges to the metal of the wra per sheet. This plate in effect constitutes t e bottom of the tank compartment and as the wrapper sheet is maintained imperforate the danger of leakage is avoided. In each tank compartment, this cover plate of the trough'is provided with an outlet opening controlled by a valve and the operating means for theseveral valves extends to the exterior of the tank at the I topthereof whereby any selected valve may be opened and closed at will.

In a tank of this construction,

allowed to flow into the trough from a sethe liquid lected compartment may be drawn oil from a construction, however, involves the provision of an outlet opening below the level of the liquid in the tank and that is considered objectionable. Instead, therefore, a siphon may be provided for drawing off the liquid from the trough by the use of a'siphon, the'bend of which is located above the liquid level. Such a siphon may be located outside the tank, preferably immediately adjacent to its rear end wall, or, if desired, it may extend from the trough up through the rearmost compartment of the tank and through the top wall of the tank and then bend down along the rear wall. For the operation of such a siphon, a manually operated pump may be provided on the vehicle for starting the flow from a compartment out through the siphon, the flow being continued through a by-pass around the pump. Such a construction is illustrated and described in an application filed by me January 21, 1925, and serially numbered 3776. Such a construction as that'above outlined involves a possibility of inaccurate supply of liquid if the tank compartment-s are relied on as measures and if leakage occurs at the valves of one or more of the compartments. This may be guarded against quite effectually by providin a. siphon for each compartment for eifecting the flow of the liquid from thatcompartment into the trough. With such an arrangement the liquid could be withdrawn from the trough by a faucet at the rear end thereof or by a siphon additional to the several individual compartment siphons arranged as above set'forth.

These and other features of the invention will be better understood by reference to the following description taken in connection with the accompanying drawing, in which Fig. 1 is an elevation of a tank embodying the invention adapted to be mounted on the frame of a vehicle; Fig. 2 is a transverse section of thetank shown in Fig.

.the top and the sheets being unpierced at any point below the liquid level line. Each of the plates 5 is extended below the wrapper sheet to form an extension 7 preferably flanged as shown at 8 and these several extensions 7 are employed for supportlng the tank structure and for stiffening its construction. In Fig. 2 openings 9 are shown in the extensions 7 to receive pipes to which the extensions are welded for the purpose of strengthening the construction and making it much more rigid.

The wrapper sheet 6 of each compartment is shaped at the bottom thereof as shown at 10 to form a trough extending in a direction parallel to the axis of the tank, the bottom wall of this trough being therefore integral with the side walls of the compartment itself.

A plate 11 is then mounted in position to form the bottom wall of the tank compartment and the top wall of the trough 10. This plate 11 may be of rectangular shape and of the width of the top portion of the trough and its lateral edges are welded to the wrapper sheet. In each plate 11 is an opening controlled by a valve 12 mounted on the end of a rod 13 which extends entirely across the tank compartment and out through the top thereof. A frame 14: secured to the plate 11 serves as a guide for the stem 13 and a spring 15 coiled about the stem urges the valve 12 to its closed position. At its upper end the stem 13 passes through a suitable stufiing box and an arm 16 mounted on it is adapted to be engaged by a lever 17 on a rock shaft 18 to lift the stem and thereby open the valve. Each of the several compartments of the tank is built up in a similar manner and each is provided with a valve; and the valve operating mechanism including shaft 18 and arms 17 -is so constructed as to permit of selecting any of the several valves and opening it so as to discharge liquid from the compartment controlled by that valve.

The extension 7 of the partition plate 5 is provided with holes as indicated at 19 which connect the sections of the trough so that a continuous trough is formed running the entire length of the tank along the bottom thereof parallel to the axis and into which the liquid may be allowed to flow from any selected compartment by manipulation of the valve of that compartmeht.

Suitable means are rovided for regulating the flow of the iquid out from the trough. In Fig. 1 I have shown a faucet 20 of the type commonly employed on tanks for dispensing gasoline mounted in an opening in the rear wall 5 of the tank structure in communication with the end of the trough. Provision for withdrawing the liquid in this way is considered objectionable because it involves the use of an opening located below the level of the liquid in the tank compartments. To obviate this objection a siphon may be provided as shown at 21 connected at one end to the trough and extending up to a point above the liquid level and then down to suitable dispensing devices. In Fig. 1 the upwardly extending leg of the siphon is shown as located within the rear compartment of the tank, though if desired it may be outside the tank, preferably adjacent to the rear end wall 5. A hand operated pump may be rovided on the vehicle for starting the flow rom the trough up over the bend of the siphon and if desired a valve-controlled port may be provided at the top of the siphon for discontinuing the siphon action, all as described in my application above referred to.

The construction above described may be further developed to guard against the eifect of leakage of one or more of the valves controlling the outlets from the compartments,

as is shown in Figs. 3 and 4:. In accordance with these figures a siphon is provided for each tank compartment for regulating the flow from that compartment into the trough. For this purpose the plate 11 forming the bottom wall of the tank compartment and the top wall of the trough is pressed to form a sump 22 which has a plate 23 welded in position over it. The valve 12 controls an opening in this plate 23 and therefore controls the flow of the liquid from the tank compartment into the sump 22. The liquid is withdrawn from this sump by a siphon. In Fig. 3 a pipe 24 is shown as having its end secured in another opening in the plate 23 so as to be in communication with the sump 22 and this pipe extends up through the compartment to a point above the top thereof. A second pipe 25 with a closed end fits over the upper portion of the pipe 24 as shown and its lower end is closed by an annulus 26. A pipe 27 connects the lower portion of the pipe 25 with the trough formed by the wrapper sheet 10 and the plate 11.

Each of the several compartments of the tank is provided with a siphon structure similar to that above described for controlling the fiow from thetank compartment into the trough and the several trough sections are connected by openings 19 as shown. The liquid ma be withdrawn from the trough by a sip on 21 which may have one leg located within the end compartment of the tank or may be located entirely outside the tank and preferably against the rear end wall. I 1

In the operation of a tank of this construction the valve 12' of a selected compartment is opened and suction is applied to the outlet end of the siphon 21 in any suitable manner, as for instance by the hand-operated pump above referred to. This suction is exerted through the trough and the pipes 27, 25 and 24: upon the liquid which has flowed by gravity intothe sump 22 of the tank compartment whose valve 12 has been opened. In response to this suction the liquid flows from the sump 22 up through the pipe 24 and then down through the pipes 25 and 27 and into the trough and from the trough it passes through the siphon 21 to the outlet opening.

It will be noted that all of the forms of the invention above described include atank consisting of a plurality of tank compartments, a trough extending the full length of thetank under all of the compartments, valved openings controlling the flow of liquid from the several compartments into the trough and means controlling the flow of liquid from the trough out through the suppl devices, the valves controlling the outlets rom the several compartments being subject to individual selection and manipulation whereby liquid can be supplied from any selected compartment without affecting the others in any way. This construction is preferably employed in the form above described wherein the division of the tank into ,compartments is eiiected by partition plates which are extended below the tank proper to form su porting and strengthening means and m which the wrapper sheets of the several tank compartments are shaped to form sections of the trough, which sections are connected by openings through the extensions of the partition plates.
