To all *whome't mag concern: I 5
Be it known that I, ,GURDON G. 'MATHER, a citizen of the United States. of America, residing at Detroit, in the county of Wayne and State of -Michigan,-'have invented certain new and useful Improvements in Lamp-Supports, of which the following 1s a specification, reference being had therein I to the accompanying drawings.
The invention relates to a support fora lamp in which the lamp is adapted for use particularly on an automobile. .One object of the invention is to secure a simple substantial construction in which the lamp ,has a universal adjustment upon its support.
Anotherobject is to obtain a construction in which the means for clamping the lamp in its adjusted position is operable from the outside thereof and, furthermore secures the cross brace .rod extending between the two lamps on opposite sides of the automobile. 'lln the'drawingsz" Figure l is a front elevation of an automobile; to which my invention is applied;
Fig. 2 is a cross section through a portion of the lamp and 1138, support. -A is the support orbracket member secured to the wheel'fender B, and G is the cross brace rod extending between the supports or bracket members on opposite sides of the automobile. D is thelamp-which is the shank Gpassi-n rovided with the spherical socketmember upon its lower side, which engages" the spherical bearing F at thegtop of the'suptudinally centrally-of the spherical socket member: nine shank member. having at the upper end ofthe'shank and spherical head within and engaging the spherical socket member E. The shank G also'passes through the eye-C in the brace member 0 and a clamping nut J engaging the threaded lower end of the shank serves to clamp boththe lamp socket v i rotatably'securmg said shank member.
the brace member 0 and member K For the purpose of pep-eventing the turning of the shank mem r G while turning the clamping nut J, the shank G is provided. with the longitudinal slot G located within the support of bracket member A and adapted to be engaged by the, cap screw Kthreadedly engaging the wall in the support or bracket member.
From the above description it' will be seen that the lampD may be swung in a vertical plane, due to the slot E in the spherical socket member E through which the shank G of the shank member G passes; 5 and also that the lamp D can-be rotated in a lateral plane by rotating the socket member E around theshank G. The combinationof these two movements permits of universal movement of the lamp. Due to the arrangement of the shank G passing through the slot E in the socket member E, the lamp is prevented from falling to one side or the. other when the clamping nut is loosened and thereby causing an unsightly) appearance. Furthermore the cooperating faces of the spherical socket member E and spherical bearing F beinglocated beneath *the lamp D and beneath and substantially in the vertical line passing through the center of gravity thereof make the lamp balanced, so that the tendency of its moymg out 10f adjusted position is avoided.
spherical socket member E is released through slightly unscrewing the clamping nut J. After adjustment of the lamp, the clamping nut J is again screwed tightly on to the shank G, -which is prevented from rotating by means of the cap screw H engaging the slot G therein. What I claim as my invention is:
.1. The combination with a lamp having a spherical socket member, of a support hav-- jinga" spherical bearing engaged by said socket member, 'a shank member extending through said support and provided with a spherical head, for engaging -sa1d' socket member, a clamping nut threadedly engaging said shank member, and means for non- 7 2.- ihe combination with a lamp having .a spherical socket member, of a support having a spherical bearing engaged by said socket member, a shank member extending 5 through said support and having a spherical head for engaging said socket member and a longitudinally. extending groove in the shank portion, a member secured to, said support and slidably engaging in said groove, and a clamping nut threadedly en- 10 GURDON O.
