BAXTER R. PALLAR-DY,

OF ST. LOUIS, MISSOURI.

FLASH-LIGHT SIGN.

Application led December 16, 1921.

To ZZ whom t may concer/n.'

Be it known that l, BAXTER R. PALLARDY, a. citizen of the United States, residing at St. Louis7 Missouri, have invented a new and useful Flash-Light Sign, of which the following is ay specification.

This invention relates to flash light signs.

in object ol the invention is to provide a novel and improved flash light sign having an electric circuit that is opened and closed by a` switch under control cf the belt of an automotive engine.

Other objects will appear from the followingl description, reference being made to the accompanying drawing', in which- Fig. l is a view showing my invention applied to an automobile.

F ig. 2 is an enlarged view showing the electric switch under control of the fan belt.

Fig. 3 is an enlarged sectional view showing a form of switch adapted for use as a part of the invention.

Fig. 4 is a sectional view on the line l-Ll of Fig.

ln the embodiment of the invention shown an appropriate sign or signal l is supported by the automobile, and a lamp 2 is arranged to illuminate the sign. An electric circuit `from the battery or other source of energy supplies the electric current for the lamp.

@ne of the wires 3 of the electric circ-uit leads to a binding post l on an insulation support 5 supported near the fan belt 6. The connecting wire 7 from the lamp leads to a binding post 8 movably supported in the insulation support 5 and having an arm t) adapted to be moved into and out of ccntact with the binding post et to close and to open the circuit. The contact member S'eX- tends through an opening l0 in a switch lever 11 which is pivotally supported upon a pin l2 in the insulation support 5. The lever l1 prevents the contact member 8 from becoming disconnected from the support.

Movement of the lever ll in a direction awa-v from the support will move the contactwmember 8 so las to contact the arm, 9 thereof with the binding post 4;; and movement of the lever l1 toward the support 5 will move the contact member in a direction to break the circuit. A spring 13 located between the support 5 and the lever il actuates the lever in a direction away from the support 5, thereby moving the contact member in a direction to close the circuit.

A roller 14. on the end of the lever 11 Serial No. 522,733.

operates against the fan belt 6, permitting the spring 13 to hold the lever ll in position to close the circuit. The tan belt is formed with a thick or raised portion l5 which when operating against the roller ll presses the lever ll toward the support 5 a distance suflicient to move the contact member 8 out of contact with the binding post il to ybreak the circuit.

As the fan belt is in continuous operation when the engine is ruiming it is perfectly plain that the circuit is altcrnatelv opened and closed automatically and as an incident to the ruiming of the engine. The flash light sign is thereby operated intermittently, making an attractive displav plainly observable. l

An improved sign of this construction and arrangement is of' inexpensive construction and ni-ay be easily mounted upon the automobile from which it is to be shown. The sign is automatically flashed on and olf as an incident to the operation oit the engine whether the automobile is in motion or not. lt is apparent that other equivalent devices may be employed to operate the switch without depart-ure from the nature and principle of the invention. Accordingly, I do not restrict myself unessentially or to the exact construction and arrangement shown, but what I claim and desire to secure by Letters Patent, is

l. In a device of the character described, a support having an angular recess therein, a contact member in the support intersecting one end of said recess, an electric circuit Awire connected with said contact member, an angular contact member movable buck and 'forth in said recess into and out of contact wit-h the first Contact member, an elec tric circuit wire connected with the angular contact. member, a lever engaging said angular contact member and having one end pivoted in said recess, and a spring on the support for actuating said rlever in a direction to move the angular contact member toward the first contact member.

2. In a device of the character described, a support having an angular recess therein,

a Contact member in the support intersecting one end of said recess, an electric circuit wire connected with said contact member` an angular contact member movable back and forth in said recess into and out of contact with the first contact member, an electric circuit wire connected with the angular lll) lirstcontact member, and a` devcemoving continuously in one direction when in` opera,-

tion for operating said lever-in opposition tol smid spring to .move said ,angular contact member `ont of contact with said first contactmemb'er. Y

In ya'device of the character described,

a. Support having an angulnrrecess therein,

a stationary' Contact member in vthesuloport intersecting Said recess. Van electric circuit Wire `connected with said contactfmemzber, a Inova-ble contact memberin said angular recess'movable into `and out of Contact with the stationarycontent'V Vmem-loer, an electric circuit Wire: connected with the movable con- Ltaict member, e. lever pivoted to said support and engaging Said movable Contact member and `preventing saidk movable Contact memloer from Working` .out of VSai-dA support, and la` V spring in connectioni with Said snpportffor' `actuating Said leveriin a direction to move seid. movable Contact member linto Contact' withV seid station-ary vconta-ct member.
