SUPPORT FOR INCANDESCENT-ELECTRIC-LAMP SOCKETS.
To all whom it may camera;
Be it known that I, FRANK BUoHANAn, a citizen of the United States,and a resident of Syracuse, inthe county o f Onondaga and Stateof New' York, have invented a certain new and useful Support for Incandescent-Electric-Lamp Sockets, of which the following is a specification.
This invention relates to headlights, and has for its object a particularly simple and efiicient means for supporting an 1ncaiides cent electric lamp within the casing of the headlight, and for adjusting the lamp relatively. to the axis of the light focusing means of the headlight; and the invention consists of the combinations and the constructions hereinafter set forth and claimed.
In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.
Figure l is a vertical sectional view, partly broken away, through a headlight embodying my invention, showing, in side elevation and partly in section, a preferable form of this lamp supporting means.
Fig. 2 is an elevation of the lamp supporting means looking rearwardly and downwardly in Fig. 1. i
Fig. 3 is an elevation looking upwardly in Fig. 2. n
Figs. 4 and 5 are elevations, partly in section, of modied forms of the lamp supporting means, the contiguous part of the casing being also shown.
Fig. 6 is a sectional view similar to Fig. 1, showing al third modified form of my invention; and Fig. 7 is aview similar to Fig. 3, buty partly in section, of a fourth modified form of my invention.
This headlight comprisesjgenerally, a. -casing, light focusing means within. the casing, a lamp support in the casing including a guide and a carriage having bearing means movable along the guide, the bearing means being located at one side of, that is, eccentric to, the axis of the lamp and the lamp socket carriage, and means located eccentric to the axis of the carriage and remote from said guide for moving the carriage along the guide or for holding the carriage in its adjusted position against displacement by excessive vibration and like causes.
The bearing means preferably includes a spring-pressed member or members which coact with the guide to steady the lamp.

any suitable form, size and construction. The light focusing means may be a reector, as 2, or a lens 3 carried by the door 4 of the casing 1, or'both.
As here shown the guide includes a plurality of rods 5 projecting from a bracket 6, having a base plate 7 lying against, and secured to', the rear wall of the casing 1. The bracket, as shown in Figs. 1, 2 and 3, inclines upwardly and forwardly from the base plate, and the rods are arranged at a right angle ends 8 which extend and which receive nuts 9 turning against the rear face of the bracket. Usually there are two rods 5 located on diametrically4 opposite sides of the lamp socket and itsfcarriage. 10 is the lamp socket carriage having bearing means on the rods 5, this carriage being inl the form of a circular plate havin bearings engaging the rods on diametrically opposite sides of the plate. 11 is the lamp socket projecting forwardly from the carriage and 12 is the lamp carried by the socket.
rlhe bearing means, with which the carriage is provided, as here shown, includes parts slidable 4on the rods as sleeves 1 3 can i ried on diametrically opposite edges of the carriage 10 and slidable on the rods i3 and spring-pressed means arranged on the outer sides of the rods 5 and pressing on the rods. rllhe sleeves 13 terminate at their ends in segmental or semi-cylindrical portions 13a which embrace opposing sides of the rods, that is the sides toward the carriage 10.
Each spring-pressed member or part coacting with the 'rod 5 includes a body 14 and rotating parts as grooved rollers 15 carried by the body and fitting on the periphery of the rod. Each body lll is connected to its companion sleeve 13 by means located between the rollers and consisting of a stem 16 threading into said sleeve 13 and having a head 17 at its outer end and a spring 18 interposed between said head 17 and the body 1l. The body le is in the form of a channel, and the rollers are supported between the opposing side flanges of the channel, and the stein 16 entends through a hole in the intermediate part or The rollers 15 are arranged in the front of, and in the rear of, the complete portion of the sleeve and are opposed to the segmental end portions 1da thereof. The means located eccentric to the axis of the lamp socket and remote from the rod 5, for moving the carriage 10 along the rods comprises a screw 19rsupported by the bracket 6 equidistant from or midway between the rods 5 and at one side of the carriage 10, said screw 19 being held from endwise movement relatively to the bracket and turning in a threaded sleeve 20 provided on the carriage 10, the screw havinga suitable knurled head 21 at one end. ln Fig. 1, the bracket and parts carried thereby are shown as arranged in the rear of, and extending forwardly through, a refiector 2 with the knurled head 21 at the front side of the reiiector, so that the screw 19 can be operated from the front side of the reiicctor, but as seen in Fig. 4 the knurled head, designated 22, may be located on the rear side of the rear wall of the'casing.
rIhe screw 1.9 is shown as having afreduced end 23 which extends through the bracket 6, on which end turns lock nuts 24. `Washers l25 and 2G are interposed between the lock nuts 24 and the rear side of the bracket, and between the front side of the bracket and the shoulder at the base of the reduced end 23. T he screw 19 is also formed at its frontend with a reduced end portion 27 on which the knurled head 21 threads, the head 21 heilig locked in position by a nut 23.
In Fig. 5 the operating screw, which is designated 29, is shown as hollow and as rotatable on a rod 30 carried by the bracket 31 and having reduced ends 32, 33 on which turn nuts 34, 35 against the rear face of the bracket 31 and the front or head of the screw 29. instead of moving the carriage forwardly and rearwardly by means of a screw, it may be pulled and pushed forwardly and rearwardly, and held in its adjusted position by a nut 3G, Fig. 6, movable along a rod 37 and threading on an expansible and contractile sleeve 33 which also moves along the rod 39 and which is carried by the lamp carriage. rlhe sleeve 38 is formed with a conical portion 39 which is slotted at 40 longitudinally, in order that it may be expansible and contractile, and the nut 36 is formed with a complemental internal conical surface 41, which when it rides onto the conical surface 40, contracts the sleeve 33 so that it grips on the rod 37. The ro(V 3T is located midway between the Iguide rods 5, that is, in the same relative position that the operating screw 19 is located in the Figs. 1, 2 and 3.l
In Fig. 7, is shown a modified form of the spring-pressed members which coact with"I the guide rods, the spring-pressed members in this figure being shown as balls '42. loosely connected to the sleeves and here shown as movable in suitable radial`passagcs 43 in the sleeves 44 on the guide" rods 45, the springs which act on these balls 42 being shown as leaves 4G each of which has an reageer axis of the carriage, and means located at one side of the axis of the carriage and re-.
