Application filed May 26, 1919. Serial No. 299,863. I

To aZZw from it may concern Be it known thatI, FRANCIS Jnnnonn, Jr, residing at Toledo, county of Lucas, State of Ohio, have invented certain new and useful Improvements in Fuel-ReserveSupply Systems for Self-Propelled Vehicles, of which I declare the following to be a full, clear, and exact description.

My invention relates to a fuel reserve supply system for self propelled vehicles, and has for its object to provide simple and inexpensive means by which a reserve supply of fuel may be maintained in the main fuel supply tank, from which the fuel is fed to the engine.

Another object of the invention is provide improved means adapted to be connected in the vacuum fuel feed system of an internal combustion engine, which will automatically stop the flow of fuelfrom the main fuel supply tank when the fuel therein has been reduced to a predetermined amount.

Another object of the invention is to provide improvedv means for controlling the discharge of fuel from a receptacle, said means being adapted for connection with any suitable form of aspirator, and arranged to extend into said receptacle to automatr cally stop the flow of fuel therefrom when it reaches a predetermined level therein.

Still another object of the invention is to provide an improved liquid control'device comprising an air tight closure arranged to be connected with an asgirator and. adapted to be inserted in a liquid holding receptacle, and carrying means which will serve to antomatically stop the flow of liquid from the receptacle when it falls below a predetermined level therein, said means being adjustable to permit the use of the liquid in the receptacle below said level and being; adapted to move automatically from said adjusted position when the liquid in the receptacle rises slightly above said level. i

To these and other ends the invention comprises certain novel features of construction and arrangement of parts, as will be here-' inafter inore'fully pointed out and claimed, it being understood that the construction is susceptible to various modifications not shown in the drawings without departing from the spirit of the invention, as ex,- pressed in the claims. I

A structure constituting one embodiment of my invention is illustrated in the accomtary section taken through the lower end, of the suction tube and valve shown in Fig.

II, and y V Fig/V is a detailed perspective view of a spring; serving as a guide and holder for the valve rod as shown in Fig. III.

Similar reference numerals refer to similar parts throughout the several views of the drawing.

, Referring to the drawings, 10 represents an internal combustion engine having a carburetor 11 and an intake. manifold '12. A vacuum feed tank 13 isconnected with said carburetor and manifold by means of conduits l4 and 15 respectively, while the main fuel supply tank lti is connected with said vacuum tank by means of a conduit 17, as shown in Fig. I. Theparts just described are intended to representdiagrammatically a suitable vacuum fuellfeed system for conveying' fuel from the main fuel supply tank to the carburetor ofthe engine in a well known manner. In carrying out the present invention a tube or casing 46 is threaded into the upper wall of the tank 16 as indicated at 47, and is provided with a downwardly extending reducedtubular portion 48 having a plug 49 in the lower end thereof provided with a fuel inlet opening adapted to be closed by a valve 50 on'the stem 51, which eX- extends upwardly through saidtubularportion 48 into the enlarged portion 46013 the tube, where it is provided with a laterally extending portion 52 adapted to engage the spring holder53 in the notch 54 at the upper end thereof when it is desired to hold the valve in open position as shown in Fig. III. A head 55on the lateral portion 52of the rod serves to prevent displacement of the spring until such time as said lateral portion is lifted out of the notch 54 to effect the release of the rod'in a manner which will presently be described. The spring 53 is 3O 7 through the tube as the hook bolt 65 is relabent upon itself as indicated at 56 and is secured to the bottom of the casing 46 by means ofa screw 57, the bent portion 56 being extended as indicated at 58 and provided with an opening 59 through which the rod 51eXtends and by which it is guided to move centrally of the tube 48 when shifted longitudinally therein. 60 is mounted to travel upon the tube 48 exteriorly thereof and is provided with a downwardly extending yoke 61 having outwardly bent ends 62 connected with the float 60 by meansof the-bolts 63 as shown in Fig. II. The lower transverse portion 64 of the yoke is provided with an opening adapted to receive a hook bolt or screw 65 of considerably less diameter than the opening, said screw being extended upwardly into threaded engagement with the stem 66 of the valve 50 as shown in Fig. IV.- The valve 50 is connected with the stem 51 preferably by a reduced threaded portion 67 screwed into the upper face of the valve centrally thereof. The opening 68 in the transverse portion 64 of the yoke is slightly larger in diameter thanthe fuel inlet opening in the plug 49, and although said transverse portion 64 may becarried upwardly by the float until it engages the bottom of the tube 48, it will not prevent the flow of fuel adjustment of the float 60 upon the tube 48. to effect an increase or decrease in the amount of fuel-in the tank at the time the valve closes, thereby providing means for varying the reserve supply of fuel when desired. The casing 46 is providedwith a screwcap 69 having upon the'lower face thereof a washer 7 6 engaging the upper peripheral edge of the casing for the purpose ofrendering the latter air-tight. A strainer 71 is mounted in the casing 46 and is connected with a plate 72 screwed upon the inner end of the conduitl'? to prevent the passage therethrough of any foreign matter.

' The invention may be assembled as a unit 7 andscrewed into proper position as shown,

after which the tube 17 is screwed into the casing 46' and the strainer 71 then placed thereon.

In use, this device operates to give notice when the supply of fuel in the tank '16 has decreased to a predetermined minimum. lVhen the tank is filled, thefloat 60 holds yoke 64 up against the bottom of the tube 48. When the level of fuel descends far enough, the float begins to descend and as off the further passage of fuel from the tank to the tube 48. Thereupon the gas engine or other apparatus being operated by the fuel ceases to function. By this means the oper-- ator is informed of the fact that hisfuel is low. If a supply of fuel is 'at hand, he naturally refills the tank, but if none is at hand as' in the case of an automobile on the road, the operator removes the cap 69 from the casing 46 and lifts the valve stem 51 manually, hooking its upper end into the bifurcated extremity ofthe spring holder 53 as shown in Fig-III, thus supportingthe 'valve 50 out of contact with its seat. The

of dust and dirt into the apparatus as well as a possible loss of the cap 69, should the automobile happen to be in the hands of careless or absent-minded drivers. lVhen the tank is again filled, the float 69 rises, oarrying with it the valve stem 51 until the latter releases itself from the holder 53, which being of resilient materiahsprings back into the position in which it is shown in Fig. 11, where it will not interfere with the movement of the stem 51 in either direction.

lVhile I have shown the invention as being connected with the vacuum fuel feed system of an internal combustion engine, it will be understood thatany suitable form of aspirator maybe connected with theorising 46, and that the device is applicable for other purposes than that'specifically pointed out herein.

. When the engine stopjs for. lack of'fuel,

it may be cranked by hand or by a self starter after the valve 50. is opened, until suflicient fuel is fed to the carbureter to permit the engine to run on its own power.

Having thus described my invention,
