UNITED STATES JO$EPII I'I. BREMER, OF TAMPA, FLORIDA.

PUSH BUTTON.

Application filed June 17, 1924. Serial No. 720,598.

To all to/ m it 'mw concern: I

Be it known that I, Josnrrr H. BREMER, a citizen of the United States, residing at Tampa, in the county of Hillsborough, State of Florida, have invented certain new and useful Improvements in Push Buttons; and I 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 tonew and useful lll'lPl'OVGlIltBIltS in electric push buttons and is designed primarily for use on automobiles for sounding the horns used in connection therewith, although the invention is, of course, not restricted to this use.

The primary object of the present invention is to provide a device of'the character stated which, while simple in construction. will be thoroughly practical and efficient in its operation.

Another object of the invention is to provide new and novel means whereby the electric circuit is completed.

Vith these and other objects in View, the invention resides in a novel construction, combination and arrangement of parts, a preferred embodiment of which is hereinafter described and illustrated in the ac companyng drawings.

In the drawings:

Figure 1 is a view, in elevation, of an electric push button constructed in accordance with the present invention.

Fig. 2 is a vertical, central sectional view of the same.

Fig. 3 is a view of one of the contact members connected to its push plate.

Fig. 1 is a view of one of the sheaths in which is inserted the shank of the contact member.

Fig. 5 is a diagrammatic view of the wiring of the push button.

Referring more particularly to the accompanying drawings, the invention com prises an insulated body portion 10, having a shank 11, provided with a somewhat enlarged head 12. The shank 11 is formed with a longitudinally extending bore 13, which extends sligthly into the head 12 and intercepts a transverse opening formed therein. Fitted within the bore 13 is a metal tube 15 which is arranged to receive one end of the electric wire 16, the same being held within the tube through the medium of a small screw 17. or the like, which passes through registering openings 18 formedin the shank 11 and the tube 15.

Arranged within the transverse opening 14, at each side of the bore 13, is a small metal casing 19, which is provided at its inner end with an inwardly directed cir cumscribing flange 20, so as to form the reduced opening 21. The contact member includes a shank 22 provided with a circular head 23 and when the different parts are. assembled, the said shank is inserted through the opening 21 from the inside of the button so that the head 23 will contact with the outer face of the flange 20. The inner end of the shank 22 is received within the inwardly directed lug 24 formed 011 the push plate 25. A coil spring 26 encircles the shank 22 and bears against the flange and the push plate so as to normally urge the same outwardly.

It is to be noted that the casings 19, are arranged at each side of the bore 13 and that each casing has associated therewith the elements referred to in the preceding paragraph. The conduit comprises a plurality of small Wires 27 located within and insulated from. the metal armor or sheath 28.

In the operation of the button, the electric wire 16 is inserted within the tube 15 with the inner ends of the wires projecting slightly into the transverse opening 26 as indicated at 27. When the contact members are compressed, the circular heads 23 thereof contact partly with the wire 16 and partly with the armor 28 thereof. The current will then flow from the battery 29, through the wire 16 until it reaches the circular heads 23 of the contact members whereupon it will pass through the heads 23 into the armor 28, which is grounded to a suitable portion. of the automobile frame. The current will then flow through the wire 30 through the horn 31 and back into the battery.

From the above, it will be seen that there has been provided an electric push button which is extremely simple in construction, yet practical and efficient in its operation and that, while a preferred embodiment thereof has been shown and described, the invention is susceptible to various changes in its specific construction and arrangement and that such changes as properly fall within the scope of the appended claims may be resorted to without departing from the spirit of the invention.

lVhat is claimed is:

1. A circuit closer comprising a body having intersecting passages, a metallic sleeve in each of the passages and out of contact with the other sleeve, an electric conduit in the sleeve of one of the passages and including a metal sheath in metallic contact with the sleeve and wires therewithin and insulated therefrom, and a slidable metal member in the sleeve of the other passage and in metallic contact therewith said slidable member being movable into and our of contact with said Wires and sheath.

2. A circuit closer including a body having intersecting passages therein, a metallic sleeve within each of the passages and out of contact with the other sleeve, an electric conduit in the sleeve of one passage, means for securing the conduit in contact with the sleeve, the said conduit including a metal sheath and wires therewithin and insulated therefrom, certain ends of the Wires extending into the other passage, and a slidable spring pressed contact member in the sleeve of the other passage and movable into con tact with the said wire ends and sheath.

In testimony whereof, I afl'ix my signature.

JOSEPH. H. BREMER.
