LAMP- GUARD.

Specification of Letters Patent.

Patented Apr. t, 1914..

Application filed May 24, 1913. Serial No. 769,673.

To all whom it may concern Be it known that I, JOHN GRAY, Jr., a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Lamp-Guards, of which the following is a specification.

This invention relates to certain novel and useful improvements in fenders or guards for electric lamp bulbs and has par ticular application to detachable guards or fenders of this character.

In carrying out the present invention, it is my purpose to provide a guard or fender whereby an electric lamp bulb will be protected against breakage or fracture and which may be readily applied to and detached from the bulb without necessitating removing the bulb from the socket.

It is also my purpose to provide a device of the class described which will embrace the desired features of simplicity, efiiciency and durability and which may be manufac tured and marketed at a relatively small cost.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

I In the accompanying drawing, Figure 1 is a view in elevation of an electric lamp constructed in accordance with the present invention. F ig. 2 is a similar View showing the guard in open position and ready to be removed from the lamp, and Fig. 3 is a view in elevation of the guard.

Referring now to the accompanying drawing in detail, the numeral 1 indicates a suitable form of electric lamp socket, and 2 designates the bulb of the lamp.

My improved guard is indicated as an entirety by the reference numeral 3 and in accordance with the present invention is formed of two sections 4, 4 constructed of wire or other suitable material and having the upper ends thereof formed to provide semicircular gripping members 5, 5 adapted to embrace the lower part of the socket 1. The opposite extremities of the sections 4, 4 are connected together through the medium of a suitable hinge joint as, for instance, a ring 6, while the clamping element by means of which the sections of the guard areheld normally in closed position is composed, in the present instance, of a single length of wire coiled centrally upon itself to provide a spring 7 and oppositely extending curved arms 8, 8 contiguous the spring, the arms terminating in hooks 9.

From the foregoing description taken in connection with the accompanying drawing, the construction and manner of employing my invention will be readily apparent. In assembling the guard, the sections 4, 4 are connected at the lower end by means of the ring 6 or other suitable form of hinge by means of which the sections may be moved relatively to one another to open and close the guard or fender. The hooked extremities 9, 9 of the curved arms 8, 8 of the clamping element are engaged with the re spective sections 4, 4 adjacent to the upper ends thereof while the spring portion 7 of the clamping element is disposed adjacent to the bottom of the guard and acts to hold the sections of the guard normally closed. In the application of the guard to a lamp, the sections 4, 4 are swung to an open position as illustrated in Fig. 2 thereby tensioning the spring portion 7 of the clamping element. The guard is now applied to the lamp and the sections thereof permitted to swing inwardly or toward each other under the action of the spring whereby the gripping members 5, 5 formed at the upper end of the sections respectively grip the lower portion of the socket 1.

I claim:

An electric lamp guard or fender comprising two sections having the upper ends thereof formed to provide gripping elements, a hinge connecting the lower edge of said sections whereby the same may swing to open and closed position, and means normally holding said sections in closed position, said last-named means comprising a single length of wire coiled upon itself centrally to provide a spring, thence extended to form oppositely disposed arms, the latter terminating in hooks.

In testimony whereof I afliX my signature in presence of two witnesses.

JOHN GRAY, JR.
