LIQUID-FEEDING DEVICE.

Application filed June. 15,

To all whom it may conaem;

Be it known that I, CLARENCE B. DES JARDINs, a citizen of the United States,,residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements injLiquid- Feeding Devices of which Ideclare-the following to be a full, clear, andexactdescription.

The present invention relates to a. liquid feeding device and, has for itsobjectto provide more particularly,v improved means .for feeding ga'solenev or other liquid fuel from. a relatively: low level such as. the supply. tank at the rear endof an automobile, to a. plurality of feed tanks or receptacles ele-; vated with respect to said supply, tank and arranged to provide a continuous flow of fuel to the carbureter of the engine orothen liquid receiving vessel, in order; that: a con? stant level may bemaintained therein, said fuel being forced into thefeed tanks by any suitable means, but. preferably by suction produced in the intake manifold of the en.- gine which, in the preferredembodimentof the invention, is connected witlrthe supply tank. through said feed tanks.

A further. object of the invention is to provide a plurality. of. vacuum controlled feed tanks, preferably. two,.which. are elevated with respect to a liquidsupply source 3 and connected with an aspirator. on suction producing apparatusand" provided with means. for' alternately. placing said! tanks in communicationwith the aspirator for the purpose of affordingia. continuous-- feed or supply of fuelto a lowlevelreceiving vessel= such as. the carbureter: of EtILlIk ternal combustion 1 engine.

A. still further object: of the inventiolnis to provide an improvedvalvearrangement for alternately opening andf closing the: airy: inlet and suction controlled; passageways; communicating with two vacuum fuel 1 feed' tanks to flIlClffIOIlI-WVIIICIL liquid. is alteiw-e nately fed and discharged. I p

Further objects, and ob ects1-relat1ng.to economies of.v manufacture and details of construction, will definitely appear from the engine by'means of the suction detailed description to-follow: p

Referring. to the drawings, 1 represents an internal combustion engine: provided I with a, suitable .carbureter '2," and an; intake manifold 3 forming the aspirator or suction producing apparatus for. lifting, the. liquidz'fuel from the 'mainlo'w leveltank or liquid 1 supply source 4 through thelconduit;

5 to [the receptacle 6 'divided" by the. partition 7 to form the independent; vacuum feed tanks having the liquid receiving chambers 8 and 9 from which the'liquid'is alternately T i fed by gravity to the carburetorthrough'the conduit 10, said; tanks or chambers being connected with the intake manifold of the with the branch pipes 13 andl l eonnected' preferably with the elbows 16 and 17 from, which extend the connections 18 and 19 pro-i jecting through the cover 20 of the tanks into the chambers 8 and 9, respectively, whichare securedoupon the cover by means of the inner and outer lockin nuts 21 and 22, as clearly shown in Fig. I

The suction conduit 11 is connected with the threaded portion 24 of the valve casing 25 from which extends through the cover 20 and into the liquid receiving chambers 8 and 9, the threaded connections 26 and 27, respectively, each being provided with a suction passageway leading to the valve chamber in which is mounted the valve 28 having the recess 29 adapted to alternately establish communication between said chambers and said suction conduit, whereby the liquid is fed first into one of the feed tanks and then into the other.

The valve casing and connections 26 and 27 are preferably integral and the portions of the casing having the horizontal passageways are preferably bored through from the ends of the valve chamber for the sake of economy in manufacture and are then plugged b means of the screws 30, as shown in Fig. IL. The connections 26 and 27 are preferably secured in position upon the cover 20 by means of inner and outer lock nuts 31 which are threaded upon said connections on the opposite sides of the cover.

The air inlet passageways for alternately venting each of the feed tanks when the other is in communication with the suction producing apparatus are formed through the valve casing 32 in which is mounted the valve 33 provided with the oppositely positioned recesses 34 and 35, as shown in Fig. IV.

The valve casing 32 is supported preferably by the elbows 36 and short nipples or connections 37 and 38, the former extending into the feed chamber 8 and the latter into the feed chamber 9 and each being preferably threaded to receive the locking nuts 39 on the opposite sides of the cover 20.

The air inlet passageway 40 leading to the chamber 8 is adapted to be closed by the valve 33 when the valve 28 is in position to open the suction passageway leading to said chamber, but at the same time, the air inlet passageway 41 leading to the chamber 9 is open. This operation, of course, is reversed when the valve 28 is in position to open the suction passageway leading to the chamber 9.

The air inlet passageways 40 and 41 are adapted to communicate with the vertically disposed passageway 42 through the recesses 34 and 35 respectively of the valve 33 when the latter is moved to its extreme positions of travel in a manner which will presently be described.

The valves 28 and 33 preferably comprise the opposite ends of a cylinder which extend through the spaced valve casings 25 and 32 to receive the washers 43 and nuts 44, as shown in Fig. V. I preferably make the valve casings in separate parts rather than integral and the valves in one piece in preference to separating them, but do not wish to limit the same to this particular form of construction.

The valve or valves are actuated by the lever arm 45 extending between the valve casings from the central or connecting portion of the valves, as shown in Figs. II and V.

The arm is actuated by the float 46 in the tank 8 when said float reaches predetermined points in its up and down movement within the tank, as will hereinafter appear.

The float is provided with a centrally disposed sleeve 47 through which extends the guide post 48, the upper end of which is reduced and projected through an opening in the cover 20 and adapted to receive the nut 49, between the inner face of which and the outer end of the reduced portion of the post is provided the packing 50, the lower end of said post being preferably projected through the bottom wall of the tank, as shown in Fig. III.

The post at its upper end is provided with a longitudinally disposed bore 51 into which extends the valve lever actuating'rod 52, said rod being also projected through the nut 49 and packing 50 and provided with a hooked end 53 engaging the arm or lever 45 within the slot 54 at its outer end, as shown in Figs. III and VI.

A transverse slot 55 in the post 48 intersects the bore 51 and registers with the oppositely positioned slots 56 in the float sleeve 47. Extended through said slots and the bottom of the rod 52 is a pin 57 which is freely movable within the slots. The opposite ends of the pin, in the preferred embodiment of the invention, project through the elongated slots 58 formed in the enlarged ends 59 of the arms 60 which are pivoted at 61 upon the post 62 extending downwardly from the cover 20, as shown in Fig. III.

Connected with the outer ends of the pin 57 are the coil springs 63 extending longitudinally of the arms 60, said springs being anchored to the clips or brackets 64 upon the side wall of the tank, as shown in Fig. III. v The sleeve 47 is provided with the upper and lower projections 65 and 65 respectively, which are preferably in the form of annular rings and which, when the float 46 is moved up and down by the rise and fall of liquid in the tank, engage the enlarged ends 59 of the arms 60 to move the latter upon their pivots, whereby when the springs 63 are carried past said pivotal points, either in the up or down movement of the float, the valve operating rod 52 will messes; f Y) beactuated by the tripping action of the tanks in communication with the intake manifold of the engine or whatever form of aspirator it is desired to use.

The liquid is preferably discharged from the feed chamber 8 through the passageway 66 in the bottom of the post 47, the latter.

being threaded exteriorly of the tank to receive the elbow 66' connected with the'conduit 10 leading to the carbureter by means of the short pipe 67 and T-head 68, as'shown in Fig. III.

Liquid from the feed chamber 9 is dis charged into the conduit 10 through the nipple 69, elbow 70, short pipe 71 and T-head 68, said nipple being threaded to receive the nut 7 2 onthe inner face of the tank and the elbow o l-the outer face, as shown in Fig. III The elbows 66' and 70 are each provided with a valve seat 7 3 and a ball valve 74 for preventing the flow of liquid upwardly, into the tanks 8 and 9, thus avoiding the mere transfer of liquid from the tank which, is under atmospheric pressure to the tank which is under suction.

The elbows containing the ball valves are adapted to be drained by removing the thumb screws 75 shown in III.

In order to prevent the possible withdrawal by suction of the liquid from the feed chamber 9 through the connection 27 of the valve casing25 in cases where the chamber 9 might be filled faster than the chamber 8 is emptied, I provide the valve 76 adaptedto be moved into engagement with the seatv 77 on the lower end of said connection 27 by movement of the float 78 on the guide post 79. when the liquid in the chamber has reached a predetermined height. By this means, the supply of fuel. to said cham her at each filling operation is. limited to a predetermined amount, which is approximately the amount fed to the chamber 8 at the time the suction passageway leading thereto is closed by the, valve 28.

I am aware that the particular embodiment of my invention, which I have here, shown and described, is susceptible of considerable variationwithout departing from the spirit thereof, and, therefore, I desire to claim the same broadly, as well as specifically, as indicated by the appended claims,

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: I
