, Application led April 25,

My present invention has particular ref er-V ence to the automatic distribution of gasoline from a visible tank.

Another object of my invention is to pro- 5 vide a. means vfor distributing gasoline through a gasoline pump controlled by a crank and the combination of co-acting elements in the gasoline tank that will open the escape valve and at the same time will close 'lo the intake valve. f

Another object of my invention is to provide a device of the class described which may be easily installed in gasoline pumps of the visible type such as now are in general 5 use. Other objectsof the invention comprise adjusting means regulatory with the desire and the need of the user; and further, wherein the construction is simple but sturdy, .easily and quickly adjusted, firmly sustained 2o when so adjusted and thoroughly adequate for its purpose.

To the attainment of the foregoing, the improvement also resides in other details of construction, combination and operation of parts, one satisfactory embodiment of which is described in the accompanying drawings.

In the drawings Figure l is a cross-sectional side view of a visible gasoline pump with the device in- 30 stalled therein.

Figure 2 is a detailed crossfsectional View ofthe intake pipe and the control elements in connection therewith.

Figure 3 is a detailed side View of the cam 35 rod and connecting gear. j

Referring now to the drawings indetail, the numeral l designates the tank into which the gasoline is pumped before distribution. Numeral 2 designates a tube mounted in the 40 base of the tank with an opening extending through the tube downward, and the tube of such a height as to be above the height of the gasoline pumped into the'tank 1. Dis posed within the tube 2 and adapted to slide therein is a cam shaft 3 which extends downward through the supporting parts of the tank 1, and has disposed on one side of the lower extremity thereof a series of teeth adapted to engage with a tooth gear, such as described in Figure 3. 1

11929'. 'sei-iai Massai-2a` y vvThe upperl extremity of theshaft 3 extends into a cap piece 2a disposed above and supported bythev tube 2. .'A vslotted openingextending on either side ofthe tube 2 to the cap`2apermits the extension: of the lugsb and cffrom the vshaft 3 and oppositely dise posedY to these'lugs a valve'stop arm and stop-per''d and 8e. v-

' Disposedin one side of the tube 2 are sev-` j eralsupp'orting lugs 2?; which maintain 'the shaft 3 in'a relative position with relation to the lugs' 3b "andBu At the lower extremity ofthe shaft 7 is astopper element7?),'7a'nd at the upper extremity of the shaft-7 .isV an 7a adapted to engage alternately with thelugs 13b and 30. Y j Y Y f Dispo-sedy inthe base of the tank lis the outletpipe4 withl a mouth a adapted to *bel elo-sed by the stopper 7b. y f f A IVPreferably 'there is mounted in the tank a float control valve comprising the cross arm member 6 with the'link Gaat one fend thereof supporting-the -loat 6b. The opposite Aextremityjofthe member 6 has a link 6c dis# posed vin connection therewith andat the extremity thereof is a valve piston 6d adapted' to move' within the'intake-'pipev 5.. -Extending from the gear member 9, which Vengages A"the/shaft '3 is the crank shaft'l() supportedby the tank support proper and extending-through 'the side thereof to the side of the tank support,the crank arm terminating in a crank handle 10a. Y'

' Thefcrank maybe turned thereby raising the shaftS. 'When this is done the lugbenf gages `with the arm`7a andraises the valve: stopper 7b' from the mouthftof the escape pipe 4, thus permitting the ygasoline in the tank'to' pass out of the tank. At-the same tim'e'that the Varm 7a israised by the lug'b, the arm 3d', with-the stopper valve 8e at the extremity thereof, closes the mouth 5a of the intake pipe 5 thus preventing any liquid from passing through the opening 5a into the tank 5.-" "The adjustment of the elements 3e andv 76 are such thatthefmouth 5a isclosedmo'- mentarilybefore the mouth etais'opened.

As a second valve control, to close the mouth 7a, there is preferably employed the Y float-7b, asheretofore described, which will 100 v fall as the gas is let out of the tank thereby` raising the valve 6d into a predetermined position so as to close the mouth 5a of the intake pipe 5.

The weightwof the shaft 3 will cause it to lower itself by gravity, and in so doing the lug ctwill engage with the arm 7a thereby lowering `the valve stopper 7b to close the mouth 4a of the outlet pipe 4,' and corre-- spondingly, the arm 3d is lowered, opening the mouth 5a and thereby permitting lgaso- ,Y

line t0- flow into the tank 1. The valve 6d is lowered simultaneously with the lowering of the shaft 3. An overflow pipe is not shown in the drawings, but being a part of the standard equipment governs the height of the gas in the tank. f l j The construction, operation and advantages of my invention will, it is believed, be understood and appreciated by those skilled in the art when the foregoing description has been read in connection with the accompanying drawings. The degree of adjustment of the several members in relation to each other is such as to take care of any requirements; and while I have here shown andl described and pointed out certain novel features of my invention, it is understood that various omissions, substitutions and changes in the form and detail of the device illustrated and its means of operation may be :made by those skilled in the art, and that I do not wish to be restricted to the structure disclosed, rbut hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim. 1

What I claim is: Y v

1. In a device of the class described, a cam shaft adapted to move longitudinally within a gasoline tank and in conjunction with said shaft, means to manually open and close an outlet pipe controlled by the lateral movement of the shaft, the movement ofthe shaft responsive to elevating and lowering the means.

2. In a device of the classdescribed, a vertically disposed shaft responsive to actuating mechanism adapted to move in. a vertical uposition within a tank, and in conjunction with said shaft, means to open and close the open@w ing in an inletpipe, said means responsive to the vertical movement of theshaft. Y c

3. In a device of the class described, a vertically disposed shaft `respons-ive to an actu'- ating means and adapted to vertical move#` ment within a fluid conta-incr and in con# junction with said shaft associated means to automatically open or close the mouthof the outlet pipe and a secondary associated means adapted to simultaneously close or openlv the mouth of an inlet pipe.

In testimony whereof I hereunto afifxmfy signature.
