HALL, or rnonmxmnn, rmmsnvnmn. 5mm LAM]? non vnnrcnns.

' Application filed September My invention relates to signal lamps for vehicles and more particularly to the lamps which are commonly termed stop lights for automobiles.

The objects of my invention are to provide a lamp of simple and rugged construction with which various signals may be given to the trafiic approaching the vehicle from its front, rear or side, and which'may' be used with any type of automatic or hand-operated electrical signal-controlling device.

These objects and other advantageous ends which will be described hereinafter, I

attain in the following manner, reference bep in Figure 1,


mg had to the accompanying drawings in which Figure 1 is a side elevation of a signal. lamp made in accordance with my lIlVeH- tion,

.Figure 2 a rear. view of the lamp shown Figure 3 a front View ofsaid lamp, Figure 4 a section on line 4-4 of Figure 2, certain of the parts being shown in full,

Figure 5 'a fragmentary view similar to Figure 1 showing a casingattached to enclose the bulb and V 1 Figure 6 a 7' c View showing one of the difierently shaped supporting arms that may be used with the lamp. 7 v

Referring to the drawings and more particularly-to Figures 1-4inclusive, 1 indicates a supporting arm in, the form of a tube havinga member 3 atone end for fastening the -arm to a vehicle and a plate 4 at theother end. Member 3 is shown in the form of an ordinary C-clamp but may be of other styles .best adapted to the particular vehicle to which the arm is to be attached. Plate4-is "secured to the arm through the medium of a flanged bracket 5 which is, threaded 'or shrunk onto the tube and riveted to the plate. Plates. is preferably stamped from sheet metal-and. has a vertical groove 6 depressed therein and a hole 7 in the groove which registers with the tube. Groove 6, hole 7 and the interior of the tube enclosethe elecjtrio wires-which lead to a vertical 'roWof electrical sockets 8secured to the plate across the groove. These sockets maybe of any standard make. Bulbs 9 are mounted in.

I .the sockets and are of different colors. The upperbulb 10 may be either green or blue.

" The central bulb 11 may be yellow or white and the lower bulb 12 may be red. Electric 18,1925. swarm. 57,098.

ASsIGNOB' '10' HAIRY IRJANGIB wires 13 leading from the sockets through groove 6 and out of tube 1 are adapted to "connected to any suitable hand or automatically operated signal controllin device. for illuminating the bulbs. 'Bul' 10 and 11 may be illuminated for signalling that the vehicle will turn to the right or to the left, and bulb 12 may be illuminated for signalling that -the vehicle will sto The lamp is mounted on the vehicle in suc V manner that the signalsniay be seenfrom the front, rear and side of the vehicle.'

In Figure 5, I have shown the signal lamp provided withja casing 14? for enclosing. the bulbs 10, ll'and 12. The light passing from the bulbs may be seen through the lenses 15 at the sides of the casing. The casing is I fastened to the plate P- by a hinge 16 at its upper end and a spring clamp 17 at its lower end. The beaded edge 18 around the easing is-gripped by clamp 17 andthus held to the plate. In all other respects the lamp is similar to the one shown in Figures 1-4 of the drawings and I- have therefore given corresponding parts .similarreference characters.

In Figure 6, I have shown the supporting arm 1 ofa bent form andprovided with a .flange member 3" instead of the fastening member 3 in Figure 1. The shape of the supporting arm 1 and style offastening member 3 maybe varied to accommodate the different vehicles. This type of arm and fastening member is especially adapted for securing the lamp to the fender of anautomobile. In all other respects'the lamp is similar tothe one shown in Figure 5 and I have therefore given corresponding parts similar reference characters.

When the lamp is inuseand either of the bulbs 10, 11 or 12'is illuminated togive a signal, the signal maybe seen from the front,

rear and side of the vehicle, thus informi the traflic of, the vehicles course of trave This tends to prevent accidents.

It will be seen that b providing the lamp with difierently colore bulbs to give diflerent signals, a. simple lamp may "be made which may beused without a casing, and if provided with a casing, requires butone compartment for all the bulbs. I

While I have described my invention as taking a particular form itwill be understood that the various parts'may be changed without departingfrom the spirit thereof, ll.

and hence I do not myself to the precise construction set forth, but consider that a hollow supporting arm, fastening means on one end of the arm, a flat plate, means for securing it to the other end of the arm substantiallyperpendicular thereto having row of electrical soc an indentation therein extending substantially the length ofthe plate, said indentation opening into said su porting arm, a vertical l ets secured to the-plate over said indentation, bulbs for displaying difierent signals mounted in the sockets, and

electric wires, connected ,with and hidden behind the sockets, passing from the sockets .throughthe'indentation to the arm.

2. A .si lamp for vehicles includinga tube, a 0 amp fastened to one end of the tube, a flanged bracket secured to the other end of the tube, a flat late secured to the bracket hav' an in entation extendin substantially t e. lengthof the late, sai

over and hiding said indentation, bulbs for displaying different signals mounted in the soc ets, and electric wlres connected to and hidden-behind the sockets passing from the sockets through the indentation to the tube.

3. A signal lamp for vehicles including a tube; fastenin means on one end of the tube; a flange i culhely fitting over the other end of the tube; a at bracket and having a vertical groove extending through the center substantially the length thereof and an openin in the groove communicating with theintenor of the tube; .a vertical row of sockets secured to the plate across and covering the groove; bulbs mounted inthe sockets, electric wires connected to the sockets and passing in the groove and through the openlng and the tube, said plate qha'vin one'end formed to provide a socket for a ingedcover, and means on the opposite end for securing thev cover in closed position. .7
