FUEL METER FOR AUTOMOBILES Filed Dec. 8, 1926 2 Sheets-Sheet 2 gnmx INVENTOR I CLAUO SIM/vows ATTORNEYS 1 Patented June 24, 1930 CLAUDE SIMMONS, F RENO, NEVADA FUEL METER FOR AUTOMOBILES Application filed December 8, 1926. Serial No. 153,441.

This invention relates to fuel meters for automobiles and it has for one of its objects the provision of a device of the character described, which will measure and register the amount of fuel consumed by an automobile.

With the foregoing object in view, together with such other objects and advan .tages as may subsequently appear, this invention resides in the construction and ar rangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of my device;

Figures 2 and 3 are respectively sections taken, on lines 22 and 373 of Figure 1;

Figure 4 is a vertical section of the device similar to Figure 1, but showing the float in lower instead of raised position; and

Figure 5 is a vertical section taken on line 55 of Figure 1.

Referring to the drawings for a more detailed description thereof, the numeral 7 in 'dicates a fuel tank provided with a removable cover 8 in which there is an inlet 9. The tank is divided by partition 12, which divides the tank into an upper compartment 15 and lower compartment 16. To the cover 8 of the tank is secured a pipe 18; this pipe may be connected at one end to a source of fuel supply so that the fuel may pass thru it into the inlet 9 and thereby enter the compartment 15 of the tank. While the tank shown in the drawing is of the gravity feed type, it

should be understood that the principles of the present invention may be applied to a suction feed tank.

A valve 21 is adapted to open and close the opening 9, this valve being secured to a rod 22, which is provided with collars 23 and 24 adjacent to the upper end of the rod 22 and secured thereto near the lower end is an enlargement 25, the'purpose of which will hereinafter be explained.

To the lower end of the rod 22 is secured a valve 27, adapted to openand close the opening in 'a tubular member 28, which is fitted into an opening in the partition 12.

A float 30 is provided in the upper compartment 15 and is adapted to slide up and down on a rod 31 between an adjustable stop 32 fiXed on the rod and a stop 33 near the top of the rod. The upper end of the rod 31 is pivotally connected at 35 to a bar 36, which is fulcrumed at 38 to a member 39, which depends from the cover 8.

The bar or lever 36 is provided with a projection 40, making it a bell crank lever. It will be seen that the movement of'the float against either of the stops 32 or 33 will actuate the lever 36. The bar 36 is pivotally connected at 37 to a link 42 which is pivotally connected at 43 to a lever 45. The lever 45 is pivotally connected at 46 to a depending member 47 of the cover 8. At 50 a rod 51 is pivotally connected to the lever 45; the rod 51 projects upwardly thru the cover 8 and is pivotally connected at 52 to the lever arm of a counting device 55. A lever 57 is pivotally connected at 46 to the depending member 47 of the cover 8. The levers 45 and 57 at their free ends have cross arms 58 and 59 respectively. To the corresponding ends of the mentioned arms are secured helical springs 60. The cross arm 59 is recessed at 61 to receive the reciprocal rod 22. The cross arm 59 is independent to work between the collars 23 and 24 to reciprocate the rod 22. It will readily be seen that the movement of the float against the stops 32 and 33 will move the lever 36, which in turn will effect a movement of the link 42. The movement of the link 42 moves the lever 45, which moves the rod 51, which is connected with the counting or registering apparatus 55.

The movement of the lever45 is efi'ected thru a spring to cause the cross arm 59 tively close together.

The fuel enters the inlet 9 when the valve 21 is in open position and as the fuel rises in the compartment 15 the float also rises until it contacts with the stop 33, by which it is effective to actuate the lever and link mechanisms to cause the valve 21 to be moved to closing position and thevalve 27 to open position. When the valve 27 is in open position, the fuel flows into the lower compartment 16 from which it is withdrawn and passes thru a pipe 16 to the carbureter. As the float falls it comes into contact with the stop 32 and reverses the rod 22 connecting the valves 21 and 27.

While I have described one embodiment of my invention, modifications thereof may be readily devised without departing from the spirit of my invention,'and it is to be understood that such modifications come within the scope of the appended claim.

I claim:

An apparatus of the character described, comprising a receptacle having alined valves in the top and bottom thereof, a common rod operating the valves having an oval enlarge ment thereon, spring fingers yieldingly gripping the enlargement to oppose movement of the same from one end position to the other, and a float control for said rod.

CLAUDE SIMMONS.
