A coil spring 31 surrounds the shaft 23 and has one end secured thereto as indicated at 38 with its other end attached, as indicated at 39, to the arm 29. The
Attached to or formed integral with the reduced end l8 of the tube is a'substantially cylindrical-sh'aped head 40,.the bottom endof the skirt 2| resting upon said head asshown in Figure.
1 of the drawing. The head 40 is formed with a chamber 4| which entirely surrounds the. tube.

Extending upwardly from the head 40 within the skirt 2| is a cylinder 43 having communication with the chamber 42. l The upper end of ,the cylinderiselosed by m'eans'of a cap 44formedwitha central opene ing 45 and apertures .46;fo'r permitting the es: capement of air as the piston is moved upwardly through the cylinder 43, h piston, 41 mounted on a rod 48 reciprocates withinthe cylinder 43 I the spring I1.

As thejpiston 41 and rod 48 are moved upwardly, the *rod 48 will contact the pawl for releasing the same from ,the ratchet 36 Of'thB diSCJZQ As the discis re leased, the tension of the spring 31 willrot'atfe the shaft 23 substantially 180 .or ,until one. of the pins 33 contacts the arm 28jtoiro'tate the'cam. 26 As the cam is rotatedthe valve 14 isurged' downwardly by means of the gagement with its seatfll5; 49 is attached to the arm 29fand isadapted to'be compressed when the pistonrod 48f'pushes 11p: wardly on the pawl 35, said spring returning the pawl to normal position as the piston: moves downwardly within its cylinder. H
A re 'lient gasket '50 is carriedby the head and normally contacts theendbfthe' neck IQ of the tank 2|! when filling the tank 20, said gasket being protected by means of theannular continuation 60 and 6|; respectively, ofthehea'd 40. The head'40 and gasket are of a suitable. diameter to fully cover various sized" gasoline tank necks. The gasket 50. is also of suitable thickness so that the" operator does not have to use undue care in placing the same in, a horizon tal plane with the t'opo'f the neck |.9in order' to,
haveatightjoint,
Extending from the,.,chamber ]4|,,isl'a tubular passage 5|, said passage communicating with the chamber 4| and terminating in thev'jallof the 'skirt'2l- The-passage 5| permits the esca-pement of air from the'chamber 4|, said air bein'g' expelled while filling the tank; Air fro'm thetank.
is carried'tof the chamber 4| "through the medium of a segmental-shaped pipe 52, said pipe terminatingin close proximity to the submerged end of the tube I0 and forming apassag'eway'53 having communication with the chamber 4|.. Air being expelled from the tank will bedischarged through the passage 53 into the chamber 4| and out through the passage 5| untilthe tank. has been filled and the lower end of the pipe 52 completely submerged in the gasoline. The remain ing air within the neck of the tankYwill com-. pressed in the chamber 42 and cy1inderf4 3' as will be hereinafter describedy In the operation of the device, the operator. when instructedto dispense aquantityof gasospring l1 into en- A U-shaped spring compression of air will then be compressed in the; I
line into the tank 20 will insert the end of the tube l0 within the neck IQ of the tank until the gasket 5|) is seated upon the end 'of the neck. The knurled disc 25 is rotated clockwise until one of the pins 33 contacts the arm 28. Turning the disc 25 will, of course, rotate the shaft 23 and at the same time wind the spring 31 a half turn, and as the disc 25 is rotated substantially 180 in a clockwise direction, the end of the pawl 35 will engage the notch 36 of the disc 32thereby preventing counter-clockwise rotation of the discs and shaft. When rotating the disc 25 and shaft 23, the cam 23, being locked to the shaft 23, will rotate with the same lifting the valve I4 from its seat l5 against the tension of The position of the several parts when'lifting the valve is shown in Figure 1 of the drawing. If desired, the face of the disc 25 can besuitably marked for indicating the open and shut positions of the valve |4. With a slightpressure now exerted downwardly on the resilient gasket 50, the operator opens the-.usual gasoline filler valve, not shown, and thegasoline mental-shaped pipe 52. The position of the pipe 52 is such that nothing but .dry air willbe discharged therethrough. The air from the chamber 4| is then expelled to the atmosphere throughthe tubular passage 5|. -An uninterthe; tank and when the flow of the gasoline reachesthe level indicated at 55, which is the topof the tank 20, air willbe displaced at a higher velocity and when the gasoline has reached the level indicated at 56, the end of the segmental-; shaped pipe 52 will be submerged thereby -pre.-
eluding further expulsion of air. This sudden opening 51andchamber urging the piston upwardly againstthe tension of the spring 54 until the rod 48 contacts the pawl 35 torelease the; same from the disc 36; The spring 31 will then rotate the shaft 23 in a counter-clockwise direction until a pin 33 abuts thearm-28.
This actionwill release the cam 26 from thec valve |4 permitting said valve to'be returned toits seat or to a closed position shutting off;
the flow of gasoline before it can riseany higher in the neck l9. movement of the disc25 and feels the jar of the valve I4 closing,- it is his signal thatthe; hasfbeen filled. Hethen releases the lever of. the usual filler valve-shutting off the flow of gas-- oine from the pump. The action of the-piston 41 to release the pawl '35 and the spring 31 for rotating the shaft 23 in a counter-clockwise d1- rection to close the valve 14 is sufficiently rapid to, prevent the overflow of gasoline from the.
neck Hi. In other words, thedevice is...designed to operate before any material quantity of pressure has had time to accumulate in the neck of thetank. 'Therefore, the seams of the tank are not. subjected to prohibitive pressure and .the lowerpressure enables theoperator to easilychold the resilient gasket 50 in position-on themeck of the tank. There is also eliminated the possibility of any air locks being formed tank or the neck of the tank during the filling p rat The chamber 4| in addition to forming a for permitting the escapement of air from with-; in thewtank. acts as a reservoir when the lower.
rupted flow of gasoline will be discharged into When the operator notes-"the,
end of the tube 52 becomes submerged. Gasoline rising within the neck I9 will flow through the opening 53 into the reservoir 4| but before displacement through the opening 5| takes place,
the valve l4 will be seated. Thus the chamber 4| allows the valve l4 time to act and the bevelled surface 4| allows any gasoline contained therein to drain backinto the tank through the opening 53.
Also it will be understood, of course, by those skilled in the art that variations in the hereinabove described device involving the substitution of substantial equivalents for the devices described are intended to be comprehended within the spirit of the present invention and that the invention is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.
