GASOLENEJNDICATOB.

Specification of Letters Patent.

Patented Jan. 's, 1918.

Application filed March 20, 1917. Serial No. 156,077.

To all whom it may concern:

Be it known that we, IRA IV. MCBRIDE and ORA H. SHADE, citizens ofthe United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Gasolene-Indicators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in indicating devices and particularly to devices for indicating the gasolene level in automobile tanks.

One object of the present invention is to provide a novel and simple device of this character which is adapted to be rigidly applied to any of the ordinary gasolene tanks now in use on automobiles.

Another object of the present invention is to provide a device which will display a signal, visible in the day time or at night, to the driver, when the level of the gasolene in the tank has reached a predetermined point.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of a portion of an automobile showing the position of my invention in connection therewith.

Fig. 2 is an enlarged vertical sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a vertical sectional view taken on the hue H of Fig. 2.

F ig. 5 is a diagrammatic view of the wirin of the device.

Ileferring particularly to the accompanying drawing 10 represents a vertical tubular casing which is provided with the apertured cars 11 through which are engaged screws 12, for securing the device to the frame 13, adjacent the tank 13' of the automobile. In the lower end of the tubular casing there is formed an externally threadednipple 14 for attachment of a pipe 15 for conveying gasolene from the tank to the casing 10. The upper end of the casing is externally threaded to receive thereon the internally threaded flange 16 of a cap 17, this flange being spaced inwardly from the periphery of the cap. Disposed on the upper face of the cap is a disk of insulation 18, the same being secured to the cap by means of the bolts 19 and 20 located outwardly of the flange 16. The former bolt 19' is surrounded by an insulated bushing member 21, where said bolt passes through the top of the cap, whilethe latter is not thus insulated, but metallically connects therewith. Carried by the upper end of the bolt 20 is a spring finger 23 which has its free end disposed over, but normally out of contact with the head of the bolt 19. The peripheral edge of the cap 17 is threaded-for the engagement of an. internally threaded cap 24 which completely covers the parts mounted on the cap 17. The sides of the cap 24, above the flange 18 is formed with openings 25. \Vithin the tubular casing, and resting on the surface of the gasolene therein, is a cork float 26. Secured to this float, and extending upwardly through an opening 27, formed centrally in the cap 17 and disk 18, is a rod 28, the upper end of which is formed with an eye 29 carrying I therein an insulated bushing 30, for the reception of the intermediate portion of the spring arm or finger 23.

It will thus be seen that as the fioat rises and falls with the gasolene in the tubular casing, the spring finger will be lifted and lowered by the rod of the float, and that when the level of the gasolene reaches a very low point the finger will touch the head of the bolt 19.

Mounted on the dashboard of the automo bile, adjacent the casing 10 is an electric lamp bulb 31 preferably redin color. This lamp is connected to the magneto 10', of the automobile, by the wire 32, while the other grounded at 34, in the usual manner, while the bolt 20 is similarly grounded through the wire-35.

It will thus be seen that when the finger 23 touches the head of the bolt 19 a circuit will be completed through the magneto, the bolt 21, the finger 23, and the grounds, whereby the lamp 31 will be lighted for the purpose of'showing that the level of gasolene, in the tank, is low. This lamp can, of course, be seen in the daytime, but is more especially useful at night where the dashboard is not provided with electric lights.

The length of the rod 28detcrmin es the level of the gasolene at which the circuit will be closed, and it will be understood that when the level of the gasolene is proper, the lamp will be held in extinguished condition due to the fact that the finger 23 is held out of contact with the head of the bolt 19.

What is claimed is:

A circuit closer for electrical indicators comprising a vertical casing having a pipe connection at its bottom, a cap having a 'flan'ge spaced from its periphery and threaded upon the upper end of the casing, a contact member engaged through the cap outwardly of the flange, insulating material between the contact member and the cap, a spring switch finger secured to the cap at one end outwardly of the flange by means of an electrical connection at a point diametrically opposite the contact member, said spring finger extending over the contact member, a rod loosely engaged through the cap within the inclosure of the flange and connected with the spring finger, a float carried by the rod within the casing, and a second cap in threaded engagement with the periphery of the first cap and inclosing the spring finger and the contact member.

In testimony whereof, we afiix our signatures, in the presence of two witnesses.
