Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed June 2, 1905- Serial NOI whether straight, sidewise, or up or down,

and such bracket is applicable to that class of lamps used with motor-cars and other vehicles when the lamps are held or supported from two points orsockets orfrom one socket.

My invention is illustrated in annexed drawings, in which Figure 1 shows a side elevation of a portion of the lamp-bracket, partly in section; and Fig. 2 is a front elevation of same. Fig.

3 is a plan of the bracket portion of same,

showing the slot and the roughened surface. Fig. 4 is a plan of a portion ofthe lamp bracket arm at the joint. Fig. 5 is a plan, and Fig. 6 an under plan, of the serrated or roughened washer. Figs. 7 and 8 are side elevations and plan, similar to Figs. 1 and 3, of a modified construction. Fig. 9 is a front elevation of the bracket portion and washer corresponding to Fig. 7. Fig. 10 is an under plan of the washer, and Fig. 11 shows in front elevation a complete lamp-bracket and arms.

For the purpose of my invention, and referring to Figs. 1 to 6, I construct the arms a b for supporting the lamp in two pieces and form one end of each so that when the two ends are placed together they are scarf-jointed, as shown at Figs. 2 and 11, the lapped ends each having a hole 0 for passage of the bolt (1. Thus the arms a b can be opened out or moved closer together to suit the width of lamp. The lapped end of arm I) has serrations or teeth e, which engage serrations or teeth f of a washer 9, this having its .other side of convex (or concave) formation, also having teeth h or serrations for engaging corresponding teeth L of a convex (or concave) topped lug or projection of the fixed portion of the bracket 7:. The lug or projection j is provided with a diverging opening Z, having the end walls thereof curvilinear in con tour and the side walls straight and extending in parallelism with respect to each other,

as shown in Fig. 3, the smaller part being at the side farthest away from the toothed edge, and the bolt (1 passes through such hole and through the Washer g, and the ends of the arms a b and the whole are secured together by nut m on the bolt, a cotter-pin n being passed through the bolt (1 to prevent the nut leaving the bolt, so that by simply loosening the nut the arms a b can be adjusted to suit any position or angle of lighting, the flattish conical hole allowing of the bolt and the arms being adjusted for positioning the lamp to light upward or downward from the horizontal.

In Figs. 7 to 11 I show a modified arrangement in which the arms a b can not only be moved up and down from the horizontal position, but also sidewise should the lamp-bracket be slightly out of the true ver tical line, so that the arms a b can be adjusted to support the lamp perfectly level. The distinguishing feature of this modification is that the lug j has a double convex or domeshaped top 1) g, the washer 9 being also domed on its under surface to correspond therewith, so that the arms can be adjusted on the lug at any desired angle either vertically or horizontally. The slot 1 of the lug in this arrangement is made wider than the width of the bolt all round, so as to allow the bolt cl free play in all directions, and so permit of adjustment of the arms a b in accordance. The bolt (1 has a ball end 1", engaging in a socket s of the lug j. In Fig. 1 the bolt cl is shown with a flat t, which slides backward and forward in the slot Z; but in Fig. 7 the bolt (1 is perfectly round, pin it being fixed to the ball portion for engaging in a cut-away part c of the ball-socket s for the purpose of holding the bolt against rotation while screwing the nut m.

WVhat I claim, and desire to secure by Letters Patent, is

1. A lamp bracket comprising a fixed member provided with a projection having a serrated top, a washer having its lower face serrated, corresponding in contour to the top of said projection and adapted to be mounted upon the top of said projection, a pair of adjustable supporting-arms adapted to engage said washer, and a pivot-bolt extending through said projection and engaging said arms for rigidly connecting them to the projection.

2. A lamp bracket comprising a fixed member provided with a projection having a diverging opening and the upper face thereof serrated, a Washer having an upper and a lower serrated face, the lower face of said Washer conforming in contour to the top of adjustable la1npsupporting arms connected together by a lap-joint and adapted to engage the serrated Washer, and a pivot-bolt passing through said projection and engaging said arms for rigidly connecting them to the projection and to allow of the adjustment of the arms to any desired position.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
