mobiles, ofwhich the following is a specification.

The present invention relates to traffic signal indicators for automobiles and has for its object a novel construction of indicator which may be operated to indicate the direction of travel intended by the operator, and

which may be illuminated for night service.

()ne of the main objects of the invention is to have the indicator automatically illuminated when the latter is extended to a signaling position and extinguished when in a retracted or inoperative position.

\Vith the above objects in view, the invem tion consists in telescoping members which carry a pointer or indicating element upon the member adapted to be extended farthermost, and, the invention also consists in means for illuminating said indicator and means controlled by the relative positions of said members for establishing and breaking a circuit to said illuminating medium.

The invention further consists in the novel features of construction, combination and arrangement of parts hereinafter set forth and finally pointed out in the appended claims. I

In the drawings which form a part of the specification Figure 1 is a front view showing the invention applied to an automobile;

Fig. 2 is a longitudinal sectional View, illustrating in detail and in enlarged scale the construction shown in Fig. 1

Fig. 3 is a detail plan view of the pointer or indicating element; and- Fig. 4 illustrates a slightly modified embodiment of the invention.

Like reference characters denote similar like )arts throughout the drawings and speci cation.

According to the invention, the traffic sig- -nal indicator A is designed to extend transversely of the automobile B and is preferably secured to the rod C of the wind-shield by the clamps 1 and at such a height as will be convenient to the reach of the chauffeur or driver of the automobile.

The indicator vB comprises the transversely extending tubular member 1 having the tubes 2 slidably received or telescoping in the ends thereof. The outermost ends of the tubes 2 have mounted thereon the pointers or indicating hands 3 and 3, respectively, consisting of two complemental index hand sections 4. and 4 arranged and secured together with their palms opposing so as to form a transparent casing or housing for the electric bulb 5, as shownv in Fig. 3. The plugs 6 of the pointers are preferably of insulating material threaded in the outer ends of the tubes 2 and formed with an opening 7 to receive or accommodate the socket of the bulb 5.

As will be seen from the drawings, a po nter or indicator 3 is provided on each side of the automobile and is projected from the opposite ends of the outer tube member 1, and since their constructions and opera tion are identical. only one will be referred to in detail, for clearness.

- Collars 8, having the handles 9 and 9 projecting therefrom, are slidable on the outer tube and have connection with the respective inner tubes 2 for sliding the latter relatively to the tube 1, whereby the indicators 3 and 3 are extended to notify the traffic and pedestrians of the direction of travelintended. When it is desired to turn to the right, the handle 9 will be slid outwardly by the operator, whereby the indicator 3 will be extended from the right side of the automobile. On the other hand, when it is desired to turn to the left, the corresponding handle 9 is similarly operated. Asshown in Figs. 1 and 2,'the handles 9 and 9 are connected to the flanges 1O onthe outer ends of the tubes 2 by the rods 11 slidably extending through the guide. flanges 12 on the outer ends .ofthe outer tube 1. In Fig. 4, however, a slight modification of this construction is shown wherein the handles 9 and 9 are directly secured to the inner tube 2 and extend through elongated slots 13 in the outer tube 1.

The construction just described especially permits the easy application of means for automatically illuminating the bulb 5, when the latter is extendedin'to signaling position, and which illumination is desirable for night service.

The circuits to the bulbs 5 from the source I X between the handles 9 and 9. The conductors 15 to each of the indicators 3 and 3 have interposed therein a circuit breaker consisting of a rod 17 longitudinally disposed in the outer and inner tubes 1 and 2, respectively, the rod 17 being held stationary in position by the insulating block 18 adjacent the opening X. As shown, the 'outer end ofthe rod 17 extends into the inner tubes 2 for a considerable distance and has slidable thereon the contact piece 19 adapted to engage with the contact 20 car-. ried on the insulating block 21 secured to the inner end of the tube and surrounding the rod 17.

It will thus be seen that-when the inner tubes 2 are extended or projected from the stationary tube 1 so as to move the indicators3 and 3 into signaling position, the bulb 5 will automatically illuminate the indicators when the latter are moved to the ex-. tent of their signaling position; and when the indicators are retracted from this position, the circuit to the bulbs is broken and the latter extinguished. To reduce shock, due to the engagement of the contacts 19 and 20, caused by suddenly ejecting the indicator, a spring buffer 22 is interposed between the contact 19 and a nut 23 on the outer extremity of the rod 17. The contact 20,spring 22 and nut 23 are preferably secured to-- gether so that said contact and spring will also be held in proper position.

Stops 24 are provided to limit the outer movement of the tubes 2, as shown in Figs.

1 and 2, Whereas the ends of the slots 13 will, limit the movement of the tubes 2, as shown inFig. 4.
