AUXILIARY CONSTANT-FUEL-SUPPLY APPARATUS FOR. AUTOMQBILES.

Application led November 20, 1915.

To all whom t may concern:

Be it known that I, JAMES NV. IVELLING- TON, a citizen ofthe UnitedStates, residing Y at 802 First St., Jackson, county of Jackson, State of Michigan, have invented certain new and useful Improvements in Auxiliary ConstantFuelSupply Apparatus for Au tomobiles, of which the following is a specification.

This invention relates to improvements 1n an auxiliary constant fuel supply apparatu of an automobile. Y

. operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention 'by the devices and means described vin the following specification. The invention is clearly defined and pointed out in the claims.

A structure whichis a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a dotted side elevation of an automobile showing the location of my auxiliary gasolene tank and its connection to the supply tank in the rear of the car and to the carbureter.

Fig. II is a detail vertical section through the auxiliary supply tank and feed means showing the operating mechanism, all of which constitutes a single unit.

Fig. III is a detail vertical section showing the connection of the Hoat arm to the switch operating arm, taken on a line corresponding to the section line 3 3 of Fi g. II.

Fig. IV is a detail vertical section of a modification of my auxiliary supply gasolene tank and feed means wherein the pump Specication of Letters Patent.

and motor are on a mounting separate from that of the tank and switch.

In the drawing, similarreferenc-e characters referto similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

1 is an automobile, on the dash of which,

, preferably within the hood, is mounted my auxiliary gasolene tank 2 which connects by supply pipe 3 to the carbureter 1, the latter being at a lower level than that of tank 2. 5 is the auxiliary tank cover. Pipe 6 extends from main gasolene tank 7, here shown situated in the rear of the car, to `a pump connection on the cover. Cover 5 integrally constitutes the motor base 8 and the pump cylinder 9. From one side of cylinder 9 runs the inlet passage 10 which connect-s to pipe 6. A ball check valve 11 is situatedso as to permit the flow of gasolene toward the pump. On the other side of cylinder 9 is the pump discharge passage 12 which delivers to the tank 2 by the ball check valve 13. Within the pump cylinder 9 is the pump plunger 14 reciprocated by an electric motor 15 and its connections. On the base 8 is mounted the electric driving motor 15 which connects by pinion 15 to the pump driving gear 16 secured to the gear shaft 17, the journal bearings of shaft 17 not being shown. On shaft 17 is also mounted the pump eccentric 18. Within the hollow plunger 14 is disposed the pump spring 19 which maintains the plunger in operative contact with the eccentric 18. There is no eccentricring. The eccentric is a cam..

Within the tank 2 is the float 20 conrl'ected by a float arm 21 to one end of float arm rock shaft 22. Where oat arm rock shaft 22 passes through cover 5 any leakage is prevented by gland 24, the cover being pocketed at this point as shown in Figs. II and III to accommodate the structure.

On cover 5 is mounted the motor switch consisting of the movable arm 25 and the stationary arm 26. Arm 25 is pivoted at 27 and forked at 25 and 25" -so as to permit the actuating arm 23 to play between the fork arms. The switch controls the circuit 28 to the motor 15 from the storage battery 29 of the car or any other source of electric energy. It is evident, therefore, that when the ioat is at its highest or lowest point the switch will be respectively opened or closed by the action of arm 23,.and when closed the motor rotates eccentric 18 which reciprocates plunger 14J thus pumping gasolene from supply tank 7 to auxiliary tank 2, the check valves permitting the flow of gasolene in one direction. The supply of gasolene is then gravity fed from tank 2 to the carbureter and the supply is kept constant by the elect-ric pump means.

A modification of my structure is shown Other parts of this modification are the samev as those shown in my preferred structure. It is seen by this, that although the auxiliary tank will have to be mounted at a level higher than ythat of the carbureter, the pump with lits drivin mechanism, may be placed in any part o the car, but will always beautomatically controlled and operated.

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

1. In a constant fuel supply system, the combination of an auxiliary tank, a pump for the filling of said tank, an electric motor for operating said pump, a float within said tank, a float arm rock shaft Journaled in thel tank cover, a float arm connecting the float, a switch having a forked movable arm, a switch actuating arm -cover for filling the same from theY mainVY supply, an electric motor for operating said pump, an electric circuit and source of supply, a float within the said tank,connec tions from said float to control the said cir` cuit all of which are disposed on said cover as a base,`coacting for the purpose specified.

3. In a constant fuel supply system, the combination of an auxiliary fuel tank provided with a detachable cover ,hav-ing a fuel passage formed therein for discharging fuel into said `auxiliary tank, a pump connected with said fuel passage and adapted to force'fuel therethrough, means for driving said pump, and means controlled by the level of the fuel in said auxiliary tank for controlling said driving means, said pump driving means and controlling means beingmounted upon said cover.

In witness whereof, I vhave hereunto set my hand and seal in the presence of two witnesses.
