GASOLINE PUMP.

Application filed November 19, 1924. Serial No. 750,887.

Our invention relates to pumps adapted for use with gasoline or other motor-'tuels, vtor delivering the liquid Jfrom a buried container to the fuel-tanks oi' motor vehicles.

1 1t is the object otl our invention to provide a simple, durable and inexpensive pump ot' this class, especially adapted for use by 'farmers and other consumers of moderate quantities of motor-'tuch among whom it is l desirable that gasoline be bought in barrellots, then stored in such a manner as to avoid lire-hazards, and dispensed `from the storage container to the vehicle-tanks as needed. A particular object of our invention is to provide means by which the dispensing ot the motor-fuel under the conditions above noted may be elliected with a minimum of waste by leakage, spilling or evaporation, and by which the drawing of Se the iuel from the storage container may be prevented except by an authorized person.

A further object is to provide simple and etlective means for regulating the quantity ot liquid to be delivered at each stroke ol the pump.

In the accompanying drawings Fig. 1 1s a` vertical section of a pump embodying our invention, Fig. 2 is a detail axial section or' the pump-cylinder, Fig. 3 is a detail transi'e verse section on the line 3-3 of Fig. 1, and F ig. 4: is a transverse section o'l the cylinder on the line 4-4 oi Fig. l.

Our pump is intended principally to be used in connection with the metal drums or barrels in which gasoline is commonly sold, and which constitute substantially the minimum wholesale quantity in which the fuel may be bought. The quantity of inflammable material contained in such a barrel is too large to permit storage thereof in a building without causing an excessive lirehazard, and it is our intention, therefore, to utilize one ot the metal barrels as a permanent container or storage tank, by placing the saine underground, connecting the pump therewith so that the contents may be withdrawn as required. and refilling the barrel from time to time through the return, overtlow or drainage conduit of the pump. 1n Fig. 1 the barrel 5 is represented as disposed underground, and the pump-body is connected therewith by means of the return-pipe 6, of which the lower end is screwed into the head of the barrel, and the upper end is screwed into the base 7 of the lil pump. The lower head S of the pump-cylinder is formed integrally with the upper portion of said base 7, and the latter is hollow or Chamb-ered to provide a continuation oit' the passage through the pipe G. At one side ot and integral with the chambered base 7 is a tubular arm 9 of which the lower portion extends diagonally upward and is connected with the base by an integral web or flange 10, and the upper portion extends vertically, there being an enlarged head 12 at the upper end ot the vertical portion, and the opening through said head having therein an annular recess ior receiving a packing or gasket1ing 11. the head 12 is an integral laterally extending lug 13 having a vertical opening 14 therein.

The head S is annularly groovcd to receive the lower end et the pump-cylinder 15, which is formed by a section of smooth-tinished pipe or drawn tubing. the head having a plurality of laterally extending lugs for receiving the tie-bolts 1G, and said bolts passingthrough similar lugs on the upper head 17. Said head 17 is annularly recessed to receive the upper end of the cylinder 15, which is clamped between the heads by the tie-bolts 16, suitable gaskets 18 being provided, whereby to form fluid-tight joints at both ends of the cylinder. At the center of the head 17 is a packing-gland 19 through which the pistoni-od 2() passes. At one side of the head 17, formed integrally therewith and extending upwardly therefrom, is the tubular standard 21, into which at its upper end is screwed the delivery pipe 22. Said pipe 22 is extended up to a. suitable height, and the upper portion is formed into a return-bend 23, to which is connected the hose or flexible conduit 24. At the end of the hose is a nozzle 25 having a slightly tapered port-ion which is adapted to tit within the gasket-ring 11 to `form a tight joint with the head 12 of the return-tube 9, when the nozzle is inserted therein as shown in Fig. 1. r1`he nozzle also has a laterally extending flange 2G vwith an opening 27 therein adapted to register with the opening 14 of the lug 13 on the head 12, whereby a padlock 28 or similar fastening means may be applied to prevent removal of the nozzle from the socket or mouth ot' the return-tube.

To the upper end of the piston-rod 2O is secured the rack-bar 29 which extends up be- At one side of tween the guide-lugs 30 :formed integrally with and extending laterally from the tubular standard 2l. In the outer` portions of said lugs is liournaled` a shaft 3l, the same being :termed integrally with a crank 3Q, and upon said shaft between the lugs is se cured the pinion S3 which meshes operatively with the teeth of the rack-bar 29. At the upper end ot the racltbar is a lug Sil which extends laterally above the upper end et the standard 21, whereby to engage the same as a stop to limit the downward movement ol the rack-bar and piston-rod. A stop tor similarly limiting` the upward niioven'ient ot' the rack-bar is secured adjustably upon the pipe 22, said stop comprising a pair of matingrmembers 35 having portions which lit about the pipe and are clamped thereon by means oft bolts 86 extended transversely through them.

rlhe lower portion of the piston-rod Q0 passes slidably through the piston 3T, and upon thelower end ot the rod is lixedly se- Cured the valve 38. The piston has the usual cup 39 oit pliable material arranged to torni a fluid-tight packing against the walls of the cylinder. Downward movement ot the piston-rod relative to the piston is limited by a transverse pin L l0 extending through the rod above the pieton, and upward movement of the rod relative to the piston is limited by the engagement ot the valve 3S with its seat, which is formed on the. lower side ol2 the piston. The valve 38 is thus positively actuated by the pistonrod, being closed at the beginning of each upward movement ot the rod,r and being opened at the beginningot each downward movemennthe piston being actuated only after the valve has been closed or opened, as the case maybe.

The supply or suction-pipe al is screwed into a central opening in the lower cylinder-head 8, said pipe 4l extending down through the return-pipe ti into the barrel or tank 5, and terminating near. the bottom thereof. `At the lower end o'tf the suctionpipe a check-valve is secured thereon, said valve"` comprising a body-portion 42 having at the lower portion thereot a seat Ytor the valve-ball l the body 4l2being screwed on the end of the pipe, and a spring 44 being` arranged between the end ot the pipe and the ball, to press the latter' toward its seat.

The operation ofthe pump will be obvious. Owing to the positive operation of the piston-valve, primingraoi the `pump is unnecessary, -a-sv'a'nyair in the suction-pipe,

nelaeae or in the cylinder below the piston, will be discharged `by one or two strokes oit the piston, which is actuated reciprocatingly by turning the crank 82 in alternating directions. dWhen the fuel from the storage container is to be withdrawn, the hose-noa zle` 25 is removed from the socket at the mouth of the return-tube, and after the pump has been operated to withdraw the desired amount of 'fuel the nozzle is replaced in the socket, so that loss by leakage trom the hose, or evaporation through the returnpipe, is entirely prevented. When the hosenozzle is in place inthe socket, operation of the pump would merely circulate a portion ot the liquid trom the barrel 5 through the pump, hose and return-pipe. ltelilling ol' the storage container is readily eltected through the return-pipe, after removal of the hose-nozzle from the socket at the mouth thereof. lt' it is desired to measure the tuel delivered by the pump, the stop tor limiting upward movement of the rack-bar may be so adjusted that each iull stroke o't the piston will deliver a determined quantity of the. liquid, and, consequently, a count o'l the number of strokes made will accurately indicate the volume ot' liquid discharged.

lt will be particularly noted that by the described construction we are enabled to provide an eliicient and durable pump o'l' this class at a very moderate cost, the sims plicity ol' structure being attained partly by combining as an integral unit the lower cylinder-head, the base, and the return-tube; and also by combining the upper cylinderhead witlithe tubular standard to form a support for the d,eliverypipe and for the rack-bar guides.

Now, having` described our invention, what we claim and desire to secure by Letters Patent is;

ln a structure of the class described. a storage container, a pump, a suction-pipe connectedwith the pump and extending into the contain-er, a 'flexible discharge conduit connect-ed with the pump, a nozzle arranged at the end ot said discharge conduit, a re` turn-tube connected with the container, means forming a socket at the mouth ot said return-tube for receivingl the nozzle and forming a detachable fluid-tight connection therewith, and registeringmeans on the socketv andy nozzle adapted to receive a lock for retaining said parts in fluid-tight connection.
