A further object of theinvem tion 1s to provide 'an improved dispensing 'apparatus having pneumatic 'means for ele# lvating gasoline or other. liquids toapoint of discharge comprised ina filling stand or' station installation by,easily operated, manually controllable means without theuse of a pump or analogous complex mechanism, to thereby more rapidly and accurately dispense the gasoline or other liquid. A still further object ofA an `improved device of the class specified which is safe in its use and will fully com` ply with the fire regulations of various municipalities which prohibit the use of'xpres-v sure uponthe storage tanks containing inflammable oils and other liquids. Vith these and other objects -and advantages in view, the invention consists in. the prferred construction and arrangement of the several parts which will be more fully hereinafter described andclaimed. j

The drawing illustrates a sectional elevation 'of a dispensing apparatus adapted for filling static u in accordance with the present invention.l

The numeral 5 designates a portion of a garage or other storage or equipment` station adjacent to which it is preferred to install the improved. dispensing apparatus. Partiallyunder or at one side of the garage 5, in a pit or cellar 6, is located a .main storage tank 7 having suitable bottom supports 8 restin on the bottom of the' pit or cellar, and leang up through the door or 'curbing the top of-the tan nected to thev top`of, vthe f flow return pipe 14' of suitable length and the invention is to provide:v

ns or stands and constructed A 9 Von which the garage is lo. ited, or at one side ofthe latter, as the 'case'- may be, is a tillingor supply pipe 10, which opens into k lfand lhaving a closure 6% plug 11. Connected -to the bottoxnof the tank.7 is a discharge pipe 12'provided with a suitable 'cheek valve 13, which opens in a directionitopermit .of 'the discharge of the /contents of the tank but closes against back 65 flow, 'as .illustrated in the drawing. Contank/ is an overextending far enough .to have its upturned end 15 disposed inV` central relation to and W' below an opening'l through the floor or' curbing-9 ,for a lpurpose which -will be presen'tly explainedf; An 'auxiliary or pressure tank 1141s'also supportedlon the' bottom et the pit or .cellariand has a pipe or tube 18 75 extending `transversely fo'f -the Ylower por- Ntionl thereof, oneiend of. the latter pipe or connected tothe discharge. pipe tube, being, 12,-as at19,'the,check valve 13 being inter,-

eor tube 18 and the 80A osed betweenthe pip The auxiliary or pres-1 discharge pipe. 12.

ily, closed except where 1' suretank 17 is ful v are made therewith, and

pipe l connections the discharge pipe-l8` has a'supply nipple 20 -extendingupwardly into the tank 17 and s is provided with a gravitating valve 21 on 'its upper e'nd. The s upplynipple, which is inthe form Vofan angular branch pipe or tube of short length,l permits the contents ofthe tank '7 to freely flow upwardly therel 90 through from the pipe or tube 18 through 'the check-valve 13, into the pipe 12 and thence into the tank- 17. Adjacent to. the filling'nipple or branch 20 isan outlet noz\ zle 22 which has its upper end extending-0 into the tank 17 and its lower extremity 23, which is bent and 'of reduced area, extending into the pipe 18. in the directionof the outlet.end 0f the said pipe 18. The discharge end of the nozzle 22 is lot reduced 1U() cross-section.

On the floor or curbing 9 a hollow pedestal 24 is mounted over the opening 16, the said pedestal preferably tapering from -its lower to itsupper extremity and having a reduced tubular neck 25 and having at its upper end a supporting flange 2G on which is mounted a transparent receptacle 27 having scale marks thereon, representing in the no present instance'a capacity of live vallons. On top ofthe receptacle 2T is a closing cap .28, which carries an illuminating globe 29 havin a suitable lighting means 30 therein and-a provided with suitable indicating matter such as the word asoline for attractive purposes. A; re uced. discharge pipe section 31 connects with the end of the pipe or tube 18 opposite that-towhich the discharge pipe 12 is attached and is prolower end to the uptu'rned -end 15 of the overflow return pipe 14 ,and also having a smaller pipe member 36 fitted 'therein for vertical sliding movement. The pipe 36 ex. tends upwardly through a gland or packing collar 37-fitted in a suitable opening 38.in

.the flange 26, the upper end of the pipe member- 35 having ja gland or packing 39 therein through which thesmaller pipe` member 36 has sliding movement. The

' lower end of the pipe member-36 has apacking ring or analogous device 40'f`nied lthereon and snugly engaging the inner surface of y 'the pipe member 35. vBy this means a non-r l k bl t' bet th all ea a e comme lon Ween e Sm er tank 7 downwardly through the pipe 12 and pipe member 36 and the ipe member 35 and the flange 26 is provide and vertical movement of the pipe member 36 is made possible. The pipe member 35 remains stationary but the pipe member -36 may be projected upwardly and downwardly within the receptacle 27 as may be desired in accordance with the quantity of oil orliquid to be dispensed. To effect an accurate movement 'of the pipe 36 it is provided witha-hand operated projection 41 within the pedestal 24 and so arranged as to cooperate with a scale 42 corresponding to that on the receptacle 27. The scale'with which the projection 41 cooperates in thev present instance. is'shownapplied to a door 43, which gives access to the interior of the pedestal for operation of the several devices which need attention or manipulation to effect a raising and dispensation of gasoline Vor other liquid and to cut ofi' the latter when the proper quantit has been 'measured, as `will be shown y the scale on the receptacle 27.

Connected to the 'to of the auxiliary or pressure tank 17-and lient at an angle and extending part way up inte the pedestal 24 is"a`vent pipel 4 4 having a petcock 45 on the upper end thereof" and readily operable through the opening in the pedestal control'led by the door` 43. The object of this vent pipe 44 is to relieve the auxiliary or pressure tank 17 of all air when it is desired toreii'ect affilling of the said tank from the storage ta};\k.7. An air pressure pipe 46- also connects with the upper portion of the tank 17 and entends upwardly linto the pedestal'a suitablfndistance and is formed with a bend or elbow-47 and then returned downwardly and at an angle, as at 48, and connected to -an air tank 49 conventionally shown as supported on the iioo'r or curbing 9 within the garage 5, or said pipe 48 may connect with any other suitable source of air under pressure. In the bend or elbow 47' of the air pressure pipe 46 a regultaing valve 50 is mounted and, may be easily 'reached through the opening in the pedestal, theobject of'this -valvc being to reduce 'the amount of air flowing downwardly to the'auxiliary or pressure tank as may be necessary and to maintain an,- air pressure only suiiicient tol fully .elevate or force the gasoline oi' other liquid upwardly .through the pipe 31 into the receptacle 27.

As 1n theiusual form of filling stands ord stations,an ordinary discharge hose 51' communicates with the bottom portion of the receptacle 27 and has a suitably valved nozzle 52, which is normally supported in a bracket or projection 53.

In starting the operationof the improved apparatus the vent pipe 44 is opened through 7 the medium of the petcock or valve 45 and the gasoline or otherI liquid Hows from the valve 13 into the ipe ortube 18 and thence upwardly througl the nipple or filling branch20 and automatically raises the valve 21 and enters the interior of the tank 17, filling the latter tank to at least a point near the closed top thereof, or in accordance with the level of the liquid within the tank 7. During this pre-liminaryvcharging of the tank 17 it will be understood that the valve 50 will be closed, and, when it is de'- sired to dispense a certain amonntof the gasoline or other liquid, the operator adjusts the pipe member 36 of the telescopic leo discharge pipe to a level within the recep' tacle 17 corresponding to thequantity of gasoline or oil to be dispensed- The upper open end of the pipe member 36 within the receptacle27 is shown in the drawing as standing on a level with thetwo-gallon scale mark. The 0perator.then opens the valve 34 of the pipel 31 and the valve 5,0 and the air pressure is regulated as may be found necessary to force the gasoline or other liquid from the tank 17 downwardlyl through the nozzle 22 in the direction of the outlet end of the pipe or tube 18, and by this means a. suction is created at the inlet end of the latter pipe and also through the ceptacle 27,I and, if a greater quantity of gasoline or oil is dischar yed into the said 4receptacle th'an is require the'surplus will f duit v18,l and this suction pass down through the telescopic overflow pipe and thence into the return pipe 14 back Ato the :storage tank 7. As soon vas the `requisite quantity or. a little more than the quantit r iiired, of the gasoline or other liqui is ischarged into the receptacle 27, the valves 34 and 50 are closed. It will' be understood that a certain' amunt of gasoline or other liquid may remain 'in the auxiliary or pressure tank '17, but the latterfis continua y replenished and a ceralways be supplied tothe tankd', rom the Umain storage ank,

`Whn the gasoline or other liquid is forced byfthe air pressure out through the pipeor tube or conduit 418, through lthe pipe 31 into the receptacle 27, a vauction is set up in the said pipe, tube or conduit -18 by the nozzle 22 in view of thetfact that thevretowards the outlet ofthe ipe, tube or conapullin'g effect on the gasoline or other liquid in the tank 7 through vthe pipe 12, the valve 13 beingA automatically opened yunder this suction stress. In Vview of this suction and the drawin of the contents of 'the 'tank 7 throng the pipe 12 into the ipe, tube or conduit 18, more or less of t e said conj of the tank'7' will be drawn into the tube or-conduit 18 Aandforced upr y througliithe pipe 31 to the recept-- 27, and zsa consequence, the gasoline ,0r oil will be fed into the pi? tube or conduit '.18 from two sou ces. s suction operation is established by the air pressure within the tank 17 andthe intensity of the 'saniewill be re lated in accordance with the pressure-oft e air entering the said latter tank.
