VISIBLE-LIQUID-DISPENSING AIEJPARATUS.

k Application filed April 25 My invention/relates to liquid dispensing apparatus of the so-calledvisible type, such as is commonly used in dispensing gasolene.

. flhe, principal object of my invention 1s ate, make it impossible 'for the operator to soinanipulate the apparatus as to cause it to deliver to the customer a lessfquantity "of gasolene than that indicated 'This is accomplished, not only by. exhibiting l to the customer the quantity of gasolene. he

is to receive-but also. by exhibitingto him .a

.flow indicator, so that he'wilLknOW what becomes-of the gasolene when he seesitids.

escaping from the visible container. Sd'long .15 as the Serve car'sign is shown he will know the gasolene can fiow 'on'ly into'the gasolene tank of his car; and so long as the I Drain-back sign is shown he will know that the gasolene can flow only back into the 2 storage tank. If the Fill-bowl sign is shown he will know, that the gasolene can flow only 'into the visible container. When the flow indicator is set so as. to exhibit any of these signs the appropriate valve may '2 be opened, andso long. as the position of the How indicator is maintained the other valves are so, guarded thatthey cannot be opened. L. I

' Some of the visible dispensing apparatuses now in use may be so manipulated as to simultaneously drain back gasolene from the visible container to the storage tank and deliver gasolene from the visiblecontainer to the car tank, thus cheating the customer. Some may be somanipulated as to simul, 'taneously be filling the serving the customer, thus cheating the oil station proprietor. Other types of visible dispensers, whether interloc 'ng orv not, may have their valves manipulated in rapid succession and the customer cheated without his detecting the fraud. 7

My invention has a flow indicator operating in conjunction with a valve interlock-- ing mechanism so as to prominently display, to the customer the efiect of the operators manipulation of the valves.

Another object of my invention is to prevent adishonest employee from cheating his filling-station proprietor employer by'simul- "taneously filling the visible container and {serving the customer from a visible dispensi ng=. .-.apparatus having a meter operated by the. fall of liquid in the contginer and adaptas being sold...

visible container and ,1924. Serial noi'zosam.

ed to show the total quantityiof liquid dispensed. 7

This invention, therefore,',ensures fair treatment for both the pump owner and his customers, and meets the requirements of the v United States Bureau of Standards and the Underwriters Laboratories.

vention selected for illustration Figure is an elevation of so much of myjimpr'oved visible gasolene dispensing apparatus as-shows the valvescontrolling the flow of the. gasolene into and out of the visible container; and the portions of the column and visible container adjacent. thereto;

Fig, 2 is a cross section on the line-"2-2 of Fig. 1; r

Fig. 3 isa'vertical section on the line 3-3 of Fig. 2;

.Fig. 4, a detail, is a top plan view of the interlocking guard ring;

Fig. '5 is a section on Fig p Fig. 6 is a diagrammatic View of my invention as though the mechanism was arranged in a straight line instead of in ring form as shown in F ig'. 2, shortened by breaking with the outwardly extending horizontal flange omitted; and

Fi 7 is a vertical section on the line 7-7 of Fig. 6, shortened by breaking and with ad'acent mechanism brpken away.

eferring now to the drawings, 1 is the column portion of the-dispensing apparatus, within which a. Jp2ump or other mechanism may be housed; is a cap of suitable design for the column, and 4 is ,an annular apron upon which is mounted the so-called visible container or glass. The apron 4 rests upon a container ifloor element 3 "which is suitably supported on the column 1 by spool-shaped spacers 1 The cap 2-may, for convenience," be made in three sections held together by screws 2". A metal screen 3 is provided to protect the container 3.

Gasolene' is pumped to the container 3 through the pipe 5, controlled by the valve 6 which has lever 7 When the container 3 has been pumped full, excess gasolene is drained bacto the storage tank through overflow pip 8, which hasno valve and is always open. 3

When gasolene is to bedispensed from the container @to a customer, the valve lever :the 4 line I 5-5 of In the particular embodiment of my inmize the fire hazard.

11 is lifted, opening the serve-valve 10 allowing the gasolene to flow through the serve-pipe 9 to the hose (not shown).

when the apparatus is shut dowiiat night, any gasolene left in the container 3 must be drained back to the storage tank to unini- To accomplis the lever 14 of. the drain-back valve 13 is raised, opening the drain-back pipe 12 and allowing the gasolene to drain through the overflow pipe 8 back to the storage'tank.

The fill valve lever 7 may be connected to any suitable valve or switch so as to simultaneously turn on power, forcing gasolene from storage to the container 3 through the.

fill-pipe 5 and till-valve 6 when said iil-levalve is opened.

When the power used is compressed air the connections may be as shown in F1g.,7,

in which an air-valve 15, with suitable pipe connections, has its lever 16 connected by link 17 to an arm 18 on the fill-valvedever- 7 so that when the operator desires to fill the container 3' and lifts the fill-valve lever 7 the air-valve 15 is simultaneously opened; By simply closing the fill-valve the air? valve is simultaneously closed so that the h v v I claim as myinvention and desire to secure by Letters Patent of the -United 'States:'

container. may be filled to any desired level.

A guard-ring 19 is seated on the cap 2 under the apron 4 and may be partially rotated by means of the shift knob 20. In the apron 4 is cut a window l 'through which a sign may be read. There may be as many of these windows 4 as are required to suitably advise purchasers of valve manipulations-.-- Mounted upon the exterior wall of the upwardly extending rib 21 of the guardring 19 is a flow indicator plate 22 with signs adapted tobeexposed to the'view of eustomersthrough,the window. Only one of these signs can'be seen at a time. Any suitable wording may be used on these signs,

the ones shown being Fill bowl to indicate that the fill-valve is open and the container 3 being filled with gasolene; Serve car to indicate that the serve-valve is open and gasolene flowing from the container 3 into the customers car; and Drain back to indicate that the drain-back valve is open and gasolene is flowing from the container 3 back into the storage tank. There Will be a flow indicator plate for each window.

Detents

23, 24C, 25, on the guard ring 19 are adapted to receive a spring pressed ball 26 to yieldingly hold. the guard-ring in any of the setting positions. The guard-ring 19.

has three keeper-

notches

27, 28 and 29; 27 being adapted to receive the guard 7 on'the fill-valve lever 7; 28 being adapted to receive the guard 11 on the serve-valve lever 11; and 29 being adapted to receive the guard 14* on the drain-back lever 14.

lVhen the guard 14 of the drain-back lever 14 is in its keeper-notch 29, thedrainback pipe 12 is open so that gaso'lene will this Lev antic impossible toopen'eitlier the serve-valve .10 or till-valve 6- until the lockis unlocked.
