2 Claims.

My invention relates to a nozzle in connection with a meter measuring device for dispensing gasoline'or the like in measured quantities from a chamber containing the gasoline aforesaid.

*Througthe medium of a novel automatic switchsideration of this specification and drawing accompanying the same in which,

1 is a general view of the dispensing nozzle secured in its normal hanging position.

Fig. 2 illustrates the nozzle in position to deliver gasoline or the like contained in the measuring meter chamber.

Figs. 3, 4 and 5 are front, side and cross-sectional. views respectively of the switch box arrangement.

Fig. 6 is a modification of the nozzle shown in Fig. 2.

Fig. 7 shows a modification of the switching arrangement shown in Figs. 3, 4 and 5.

Referring specifically to Fig. 1, 1 is a gasoline measuring container. 2 is an electric motor and 3 is a pump operated by the motor aforesaid. 4 is a section of conduit pipe containing insulated conducting wires. 5 is the delivery nozzle. 6 is the nozzle holder. 7 is a flexible hose secured to the measuring meter container to which the nozzle is attached. 8 is a switch box made of insulated material such as bakelite. 9 are connecting wires of a circuit leading from the switch box 8 to the motor 2. 10 are fastening rings that as shown. 11 are fastening rings that secure the insulated wires to the flexible hose. 12 is the gooseneck section of the conduit pipe projecting of the liquid measuring chamber.

Referring to Figs. 3, 4 and 5. Numerals 13, 14 are side contact springs of the switch proper. 15, 16 are contact screws for securing the conducting wires to the aforesaid contact springs.

The contact springs are bent at their lower ends 17. so as to conform to the contour of the walls of the sealed container 26, the latter being preferably made of glass. Enclosed within the container 26 is placed a quantity of mercury or quicksilver. 19, 20 are contact rods projecting outside of the container 26 and are integral respectively icatien Novcmiier'23, 1932, Serial No."644,013

to contacts 21, 22 inside the container. 23 indi cates the area in which the mercury or the like is located when the switch proper takes the position as shown in Fig. 3. 24 is the cover of the switch box arrangement secured by fastening screws 25, 26.

27, (Fig. 5) illustrates the design of the bottom of the switch box conformed to fit the nozzle body. 28 is a projection all around the switch box that fits snugly in the grooved portion 29 of the switch box, (see Fig. 3).

Referring to Fig. 7 which illustrates a modification of the switch box arrangement shown in Figs. 3, 4 and 5. Numeral 30 indicates the switch box body made of insulated material such as Y bakelite. 31 is the switch box cover secured by fastening screws 32 and 33. 34, 35 are opposite contact springs having contacts as shown. The contact spring 35 is secured to the counterweight 37 through the medium of insulated block 36.

The counterweight swings on journal 38. 39 and 40 are stopping pins which limit the movement of the counterweight 37 back and forth. 41 and 42 are contact screws which connect the wires leading into the switch box. conducting wire which is connected to the con tact 35. The contact 34 is electrically connected to contact screw 42.

44 are fastening rings securing the insulated wire cable to the nozzle proper.

The switch box is mounted on the head of the nozzle as shown in Fig. 6. 45 (Fig. 2), indicates the opening of an automobile tank or other container into which gasoline or other liquid flows through the medium of the nozzle pipe terminal.

The operation of the dispensing nozzle arrangement is as follows: Normally the nozzle and its associated hose connection are hung in the position as shown in Fig. 1. When it is desired tosupply a quantity of gasoline or the like, the nozzle is lifted off the holder 6 and is placed in position to feed the liquid into the tank 45. This position is shown in Fig. 2. When the nozzle is thus held, the mercury falls by reason of gravity to the bottom of the glass container 26 in the area designated as 23. This causes the mercury to connect up electrically the contact points 21 and 22 which in turn closes the circuit that operates the electric motor aforementioned. The motor operates the gasoline pump and continues to operate as long as the nozzle is held in the position as shown in Fig. 2. When by opening the nozzle valve, the desired quantity of gasoline is delivered into the automobile or other container tank, the nozzle is lifted up and hung in its normal 43 is the pigtailed 30 position as shown in Fig. 1. This causes, by reason of gravity the mercury in the container 26 to fall to the side opposite to that of the contact points 21 and 22, thereby automatically opening the electric circuit resulting in a cessation of operation of the motor and its associated pump.

The operation of the nozzle having the modified automatic switch as shown in Figs. 6 and 7 is similar to the operation of the mercury switch, in that the contacts are closed by the holding of the nozzle at the angle in the position shown in Fig. 6, which causes the weight 37 and its associated contact 35 by reason of gravity to fall against the contact 34 thereby closing an electric circuit which starts in operation a motor and a pump in connection therewith. When the nozzle is held in the position shown in Fig. 1, the counterweight 37 and the associated contact 35 takes the position shown in Fig. 7. i

It will readily be seen that my invention is capable of some modification without departing from the spirit of my invention. For instance, the switch box body in Fig, 2, or box 30 in Fig. 6

may be integrally incorporated with the dispensing nozzle.

Now having described my invention, what I claim is,

1. The combination with liquid dispensing apparatus comprising a pump, an electric motor for operating the pump, a dispensing nozzle, and a flexible hose connecting said nozzle and the pump outlet; of control means for said motor and carried by said nozzle, said control means being automatically operable to start said motor by inclination of said nozzle to dispensing position.

2. The combination with liquid dispensing apparatus comprising a pump, an electric motor for operating the pump, a dispensing nozzle, and a flexible hose connecting the nozzle and pump; of a gravity switch on said nozzle, an electrical circuit including said motor and switch and having wires, and said wires being disposed along the extent of said hose for flexing therewith as the nozzle is moved to dispensing or non-dispensing position.
