Application filed January 25, 1921. Serial 110.4395.

To all whom itmay concern: Be it known that AUGUSTUS Bowsan, late a citizen of the United States, and resident of Fort Wayne, county of Allen, State of Indiana, has invented a new and useful Improvement in Liquid-Dispensing Apparatus, of which the tollowing is a specification.

This invention relates to liquid dispensing apparatus, and constitutes an improvemen on certain features of a device of the kind disclosed in the present inventors prior Patent, No. 1,316,557, September 23, '1919. It relates particularly-to the means for controlling the supplyfof air pressure which forces liquid from a tank into a measuring head or reservoir to be delivered to a customer, and to means for disposing oi the exhaust. It also includes a new system of piping in the standwhich' supports the delivery reservoir with easily accessible structure and arrangementof the valve control mechanism for the system. While it makes use of a valve somewhat similar to that in application Serial No. 321,686, Sept. 4', 1919, the'structural combination is different.

rior patent above noted Since applicants used in a system of thekind to which the present invention may be applied, it is not necessary to'show and describe those features of such system as will be understood by those skilled in the art, and therefore -outlet pipe 15 a novel, efiicient, and ment is such that liquid is filled a priming pipe pass connection 27 the detailed mechanism line and it may of course-be placed in any convenient relation to the other parts of the system. It is provided with a pipe 11 ext tending upwardly therefrom to a point 12 convenient for filling and is also provided with a vent pipe 13 leading out to any convement place. An auxiliary tank 14 is arranged at a lower level than the reservoir 10 and is connected to the reservoir 10 by an leading from the bottom of the reservoir 10 out through the top through a cross pipe 16 and down to the auxiliary tank by pipe 17. The pipe 15 has in its lower end a check valve 18, and the arran automatica l supplied from the reservoir 10 to the tank 14 by siphon action. In order to prime the siphonjwhen the storage tank 10 is first P connects with the siphon at its highest point, and. is' closed by a ea or plug P The tank 14 is also provide with a blowofi-pipe B normall closed by a cap or plug B and through which water and sediment can be blown out of the tank. The pipe 17 is connected to a supply pipe 19 adapted to convey the liquid from the. tank 14 up to livery to a customer. It passes up through the stand 20 and is connected at 21 to the i bottom plate 22 of the graduated glass reservoir or container 23, which, as shown, is smaller than the tank 14.- The supply pipe 19 is provided with a check valve 0 between its connection to pipes 16 and 17 and the bylater described. This check valve permits to the container 23 but prevents its flowing the stand for dethe liquid to pass up.

downward in the pipe and thus prevents air entering through the container 23 and pipe 19. The glass container 23 has an overflow pipe 24 open at its top and terminating at the proper distance from the top of the container fixed on as the maximum to which the container should be filled, and it is connected to the bottom plate 22 of the con-. tainer at 25, and there is an the stand and to the main reservoir '10. Within the housing overflow pipe 26 leadingfrom' that connection down through and. the overflow pipe 26 with a valve 28 controlled by the longitudinal movement of the pin 29 to connect or disconnect the two pipes atthat point, the. purpose of connecting. them being to permit, when desired, surplus oil remaining in the container below the level of the overflow outlet to return or drain back into the main reservoir 10. The controlling pin 29 passes through a face 30 of the casing, and the hinged cover plate 31 for that casing when moved into closed position will press on the end of the pin and thus open the connection between the pipes at that point, draining the container 23 automatically if this has not been done by the operator before closin the cover plate. The usual .hose connection 32 leads from the socket 33 in the bottom plate 22 of the container 23 to convey the liquid in that container to the point desired in delivering it to a customer.

The means for causing air pressure on the liquid in the auxiliary tank 14-to force it up tothe receiver 23 consists of an air pipe 34 leading from any suitable source of air pressure and passing up the stand 20 and connected at its upper end to valve casing 35at the socket 36 illustrated in Figure 5. A second air pipe 37 is connected to the valve casing 35 at 38, and leads back down the stand and to the auxiliary tank 14. In addition to the air inlet and the air outlet pipes connected to the valve casing. 35 there is an exhaust pipe 39 connected to this casing at 40, and'le'ading down into the main reservoir 10.

The valve casing35 has extending inward from one end a chamber 41 which is of uniform cross section and preferably; cylindrical, and there is a contracted extension of this chamber at 42. In line with the first mentioned chamber and at the other end of the casing there is an enlarged chamber 43 with which the air inlet pipe- 34 connects. This chamber 43 has surroundmg the contracted ortion 42 a valve seat 44. It will be note that the connection of the exhaust pipe enters the chamber 41 near its outer end and the connection 38 for the air-pipe 37 communicates with this "chamber 41 at 45 in advance of the connection between that chamber and the connection 0. A valvemember comprising an outer ion 46 of uniform cross section fitting the chamber 41 is adapted to move longitudinally within that chamber and has a central reduced rod extension 47 extending through the contracted portion 42 and carrying on its end a valve 48 in the chamber 43 and adaptedwhen moved to the right as shown in Flgure 5 to fit the valve seat 44 and close communication between the chambers. There is a coil sprin chamber 43 bearing at one end on t e valve 48 and at the ther end against the screw hold the valve member in the position shown 1 in Figure 5 with the inlet for compressed air shut. it will be observed that when the valve member is in this position the outlet air pipe 37 and the exhaust pipe 39 are in communication and the effect of this is that any air pressure in the auxiliary tank 14 may be relieved through this valve casing and the connected pipes passing out to the main storage reservoir 10. A movement of the valve member 46 inward will serve to out 01f connection to the exhaust pipe 39 and at the same time open valve 48, thus bringing the air inlet pipe 34 intoopen connection to the air outlet pipe 37, thus causing the air pressure to operate on the liquid in the auxiliary tank 14 forcing it up to the delivery container 23. To fill that container, therefore, the operator simply presses on the valve member 46 until the required amount of liquid appears in the visible container 23, and on releasing that pressure on the valve member it automatically returns to the position shown in Figure 5, cutting off the air supply and permitting the compressed air in the auxiliary'tank to pass through the exhaust tothe main tank. This disposition of the exhaust. air reduces the explosion and fire hazard inasmuch as some of the gasoline vapor carried along with the air may settle out in the large tank 10 and the vent pipe 13 having its outlet at a remote point from the apparatus thus removes the air with Whatever vapormay be left in it toa safe distance. Furthermore gasoline vapor that settles out in the large tank 10 is saved. If the exhaust air were delivered immediately into the atmosphere,

the vapor recovered in the tank 10 by condensatlon and otherwise would be lost. It is to be noted that the valve construction for controlling the operation and connection of the parts is very simple and easy to operate and contains no parts likely to get out of order. The closure 31 on the stand,

while it covers and protects the valve member 46 against unauthorized operation when closed, does not contact with that member or move it to turn on the air pressure.

The operation of the device is as follows.

After the tank 10 is first filled gasoline is poured into the priming pipe P until the latter is filled. This fills the tank 14, the

legs 15 and 17 of the siphon, drives the air out through the check valve 0, and fills the supply pipe 19 to above the level of this valve. The cap P is then closed and made air tight, sealing the siphon. and after gaso-- line has been forced out of will operate to fill it.

The first operation in supplying a customer is' to so move the valve in the valve 14, the siphon casing 35 as to connect air pipe 34 which is supplied with compressed all #0 air pipe 37 During this absence of I 1,54s,an

extending down to auxiliary tank 14, thus subjectin the liquid in that tank to pressure whic forces it up through supply pipe 19 into container 23. This pressure cannot force ,the liquid back into tank 10 because of the check valve at the lower end of pipe 15 and itis thus forced to pass up throu h supply pipe 194- When a sufficient supp y is in reservoir 23, the air control valve in casing '35 is so moved as to out oil the supply ofa'ir under pressure to pipe 37 leading to tank 14 and at the same. time connect that pipe to exhaust pipe 39 whereby the liquid in the tank is relieved of the air pressure and the air which had accumulated in tank 14 in forcin the li uid out may freely escape throng pipe 3 and exhaust pipe 39. pressure in tank 14 and while the air therein is escaping, the liquid in supply pipe 19 would normally and naturally flow back into tank 14 taking the place ,of the escaping air and its .leve would pass below the top of pipe 17 where .it joins :pipe 16 and would thus destroy or breakthe siphon connection between tanks 10 and 14 but the check valve in supply pi 19 prevents this and this maintains t e si hon connection in operative condition. e pipe'17 extendin to a lower level than pipe 15 the weight 0 the column of li uid m it ov'erbalances that in pi 15-and t us the necessary liquid to take t 'e place of the escapingair in tank 14 automatically, asses from tank 10 totank 14 and quickly it ready for the next operation. Tjhe siphon connection is thus alw'aiys full ready for op-.

eration. It is believe that the operation by which the reservoir 23 is drained and the contents returned to tank 10 Tthrough the upper portion of supply ipe 19 above the by-pass then throu the y-pass' and down overflow pipe 26 w en the by-pass valve is opened Will be clear from what has heretofore been said without further description.

It will be-seen from what has been said above and upon inspection of Figures 1- and 6, that all'of the pipin for the" supply of liquid to the graduated 'ispensing reservoir, for the,overflow and return of any surplus supply and for draining the dispensin reservoir after a customer has been serve as well as thepiping for the compressed air to caus pressure on a liquid in a distant conceale tank forcing a supply up to the dispensing reservoir, and for exhausting the air pressure from said tank after the dispenslng reservoir is filled, and conveying the exhaust vapor laden air to a distant point throu h a main li uid reservoir, all pass up1 within the vertical hollow housing 20 ch constitutes the stand for the dispensing reservoir vin a very convenient and easily made and efficient parallel arran ment,

and that the control mechanism is all ocated apart, leavmg room between them for the transversely .extending 'valve casing 35 which in turn has connected to it on its lower side the three parallel pipes 34 for the air pressure from an outside source, 37 for the air pressure passing to the sulppl 14, and the air exhaust pipe 39 ea ing to the main liquid reservoir 10. The by-pass valve 27 connecting the pipes 19 and 26 is immediately above the valve casing 35 and has operatingmeans parallel to and immediately above the operatin means for the air pressure and exhaust va ve in casing 35, and both are adaptedto be protected by the single closure 31. The structural arrangement is thus easy to make, neat in appearance, eflicient in its action, easy to operate, and'protects the piping from exposure and the a paratus from unauthorized tamperin gt will be noted that the stand 20 constitutes not merel a support for reservoir 23,-but an enclo housing circular in cross section for the piping and valve control mechanism Having thus described the invention, what tank is claimed as new and desired to be secured by Letters Patent is:

Dispensing apparatus of the class described, including in combination a reserandreleasin said pressure and allowingjttoexhaust, t rough said reservoir, comprise 'ing a valve casing in said stand, an air lnlet pipe extending up within said stand connected thereto at one end, an air outlet pipe leading down ,said' stand to said auxillary tank connected thereto at the other end, an exhaust pipe connected thereto at a third oint near said air inlet connection and eading to said reservoir, and a longitudinally movable'valve in said casing normally leaving said air outlet and exhaust pipe in communication but when operated by a longitudinal movement closing that communication and connecting theair inlet and outi *let pipes;
