GASOLINE DISPENSING DEVICE Filed Feb. 6, 1935 wuc/wton WA. n illiams Patented Dec. 24, 1935 UNITED STATES PATENT OFFICE 1 Claim.
My invention relates to improvements in devices for dispensing gasoline at filling stations, or in other places where gasoline is sold or delivered to customers, and it consists in the combinations, constructions and arrangements herein described and claimed.
An object of my invention is to provide a device in which the use of complicated pumping mechanism which is costly to make and to maintain, is obviated.
A further object is to provide a device which is positive in action, having no moving parts except valves to open and close pipe lines, and which therefore does not subject users to loss through frequent failure to function satisfactorily, as do the more complicated devices.
A further object is to provide a simple construction which is economical in operation, since there is nothing to wear out or get out of order.
A further object is to provide a safeguard against theft by the assembly of all connections inside of the locked machine.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.
My invention is illustrated in the accompanying drawing forming part of this application, in which:
Figure 1 is a side elevation of a dispensing device forming one embodiment of the invention, and,
Figure 2 is a vertical sectional view.
In carrying out my invention I provide a casing or housing I which may be made of any suitable material, but which is preferably made of metal. It is provided with openings, such as those shown at 2, 3 and 4 for access to the interior mechanism, these openings being preferably closed by hinged doors, such as those shown at 5, 6, 'l and 8' respectively. Suitable locking means, not shown, may be used in connection with these doors so as to pr vent any tampering therewith.
Supported upon the top Ia of the casing or housing I, is a tank 3 which is preferably made of glass. This tank has at its top a relief valve 9 whose function will be explained later.
At It? I have shown a portion of a storage tank for the fuel, such as gasoline, which is to be dispensed. A filling tube H extends upwardly from the tank above the ground line l2, and terminates just inside the door 5 so that when the latter is opened connection can be made to the end of the pipe H for filling the tank l0.
A pipe I3 is provided, this pipe extending from the tank It! above the ground line. It is provided with a valve l4 and with an adjustable pressure regulator shown diagrammatically at [5. The pipe l3 is designed to be connected with a source of compressed air, not shown, so as to put the fuel in the tank It under pressure.
Extending from a point near the bottom of the storage tank Ill and communicating with the tank 8 is a pipe 16 which is provided with a valve 11. A pipe l8 extends from a sump I9 in the bottom of the tank, and is provided with a valve 29. An overflow pipe 2] is disposed centrally of the tank 8 and is provided with an adjustable extension 22, by means of which the effective length of the pipe 2| may be changed so as to register with gauge marks 23. These gauge marks, as will be observed from Fig. 1, have numbers to indicate the amount dispensed, this amount being preferably measured in gallons.
The lower end of the pipe 2 I, which is an overflow pipe, communicates with a transfer tank 24, a valve 25 being provided as shown in the drawmg.
A short drain pipe 26 having a valve 21 extends from the bottom of the tank 8 and communicates with the interior of the transfer tank 24. At the bottom of the transfer tank is a short pipe 28 having a valve 29, the lower end of this pipe communicating with the pipe It, as shown. A pipe 3!! communicates at its lower end with the tank I0, and at its upper end with the upper end of the tank 24. This pipe has a valve 3|.
A dispensing hose 32 is provided having the usual nozzle and retaining means 33 therefor. This hose communicates with a discharge pipe 34, which is controlled by a valve 35.
From the foregoing description of the various parts of the device the operation thereof may be readily understood. Normally all of the valves are closed. The tank It is filled, as stated, through the medium of the pipe II.
The valve I 4 is opened to permit compressed air to enter the interior of the tank It] until a desired pressure is attained, this pressure being indicated by the pressure valve IS The valve I4, is then closed and the tank I0 is under pressure. The tank 8 may be filled by opening the valve ll. This will permit the liquid to flow through the pipe l6, under pressure until it has reached the top of the overflow pipe 2 i, when it will pass downwardly into the transfer tank 24, the valve 25 having been opened to permit the passage of the fluid into the transfer tank. When the liquid is to be dispensed the end of the hose is put into the tank of an automobile or container and the valve 35 is turned to draw off the desired quantity of the fluid as shown by the gauge marks 23. When the desired quantity has been drained the valve 35 is then closed. This process may be repeated as long as there is fluid in the tank I 0 and pressure thereon.
If it is desired to drain the bowl 8 the valve 26 is opened and the contents of the bowl may be drained into the transfer tank 24.
The accumulation from the overflow may be returned to the tank If! against the pressure therein in th following manner. The valves I1, 21 and 25 are closed and the valves 3| and 29 are opened. Since both pipes I6 and 30 are under the same pressure, i. e. the pressure in the tank It], the pressure on the transfer tank 16 will be equalized and the fluid, such as gasoline, will flow by gravity through the pipe 28 and the pipe I6 downwardly into the tank I0. The valves 29 and 3| are thereupon closed and when it is desired to again fill the bowl or tank 8 the valves I1 and 25 may be Opened. When it is desired to clean out the tank of any sediment or of any water that may have accumulated in the tank, the valve IT is closed at the top of the pipe [6, and the valves 29 and Bi being closed the valve 20 may be opened and the pressure on the inside of the tank i ll will'then force anything which has accumulated in the sump [9 through the discharge pipe l8, after which the valve 20 may be closed.
It will thus be seen that I have provided an efiicient dispensing device in which accurate amounts of liquid, such as gasoline, can be elevated, measured and dispensed without the necessity of pumping devices, which as stated, are apt to get out of order and to deliver other quantities of fluid than they are rated to deliver, because of leakage, etc. It will be observed that the closures are so disposed as to permit easy access to the various valves for manipulating the device in elevating the liquid into the bowl, in draining it from the bowl, in dispensing it, and in controlling the overflow as well as in cleaning the tank In of accumulations therein and in returning the liquid to the tank l0 without the necessity of relieving the pressure in the latter.
I claim:
A dispensing device for liquids, comprising a storage tank for the liquid, means for introducing air under pressure into the tank, an elevated dispensing tank, controllable connections between said tanks for conveying liquid from the storage tank to the elevated tank, means for discharging the dispensing tank at will, a transfer tank disposed below the dispensing tank and above the storage tank, means for draining the contents of the dispensing tank into the transfer tank, means for returning the contents of the transfer tank to the storage tank against the air pressure in the latter, said last means comprising a controllable pipe extending from the storage.- tank to the top of the transfer tank, and a controllable pipe leading from the bottom of the transfer tank and communicating with the storage tank.
