Abstract

204,418. Frost, S. J. July 4, 1922. Mounting globes, shades, and reflectors directly on rods or tubes. - A spring holder formed as a stamping from a single sheet of elastic metal comprises a sheet metal ring a having upwardly extending arms c which engage with the lamp socket d to support the reflector &c. e, and downwardly depending arms b which, on insertion of the lamp bulb, engage either with the bulb f or its metal plug g and are forced outwardly so as to press the upper arms c firmly into engagement with the screw-threads of the socket d. The Provisional Specification also states that, in one form, the upper arms, two in number, may be in alignment with the lower arms, and may extend first upwards, and then inwards to the socket, the lower arms extending from the outer edge of the ring. The edges of the upper arms may form part or whole of a circle. In another form, the ring may normally be curved symmetrically in diametrically opposite positions so that on engagement with the socket it tends to straighten, and the socket-engaging arms extend inwards but not upwards from the inner edge of the ring in alignment with the lower arms.
