7 the right and left hand signal means in the form of an arrow with an electric lamp for illuminating the arrow, the current being automatically turned on when the arrow is moved to operative position, with means for closing the circuit of the lamp by hand when a stop signal is to be given.

This invention also consists in certain other features of construction and. in the combination and arrangement of the several parts, to be hereinafter'fully described, il-

lustrated in the accompanyingdrawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in wh1ch:

Figurel is a to plan view of the device. Figure 2 is an e evation, showing portion ofthe vehicle in dotted lines.

Figure 3 is a section on line 33 of Figure 1.

Figure 4 is a section on line 44 of Figure3. Figure 5 is a ure 3.

In these views, the numeral 1 indicates an upright cylindrical casing which is formed with a bracket 2 adapted to be fassection on line. 5-5 of Fig- .tened to a front part of the vehicle at the top thereof, with the casing extending through a hole in the top of the vehicle, as shown in Figure 2. A hollow, spindle 3 passes through the casing and has a cap 4 on its upper part which fits over the upper end of the casing and a lamp casing 5 is connected with said cap,the casing 5 being horizontally arranged with a lens 6 in one 29 in the member 28 tending to force the end thereof and said casing has a vertically arranged neck 7 which is suitably fastened to an upright flange 8 on the cap. The spindle 3 extends above the cap into the lamp casing andhas a socket for a lamp bulb 9. 65 An arrow 10 is fastened to the lens carrying end of the casing in such a manner that the rays of light from the lamp will illuminate the arrow.

A disk 11 is connected with the lower end 80 of the spindle 3 and closes the lower end of the casing 1, said disk having a rotary fit in the casing. A stem 12'is threaded in the disk and a handle 13 is fastened to the lower end of the stem so that by turning the handle, the spindle 8, with the cap and lamp casing and the parts attached thereto, will be turned in relation to the casing 1. A switch casing 14 is attached to the lower end of the casin 1 and a button 15 is car- 70 ried by said casing, the button being nor- 'mally held projected by the coil spring 16 within the casing 1 1. The body of the button is provided with a socket in which is arranged a coil spring 17 which acts to hold the headof a headed'stud 18 against the bottom plate 19 of the button, the stem of thestud passing through a hole in said bottom plate. a a

A ring 20 having a recess 21 therein is fastened to a ring 22 carried by the spindle 3,"the ring 20 being insulated from the ring 22 by the insulation 23. A conductor 24 connects thering 20 with one of the terminals of the lamp socket 'and a conductor 25 is 'a ball 27 arranged in a tubular member 28 connected with the bracket 2, a coil spring 5 ball outwardly. This arrangement acts as a lock for holding the spindle 3 and the parts associated therewith in adjusted position.

When the parts are in a neutral position,

the ball will engage the middle recess 26 of no the valve 22 and thus'hold the parts with the arrow pointing rearwardly. In this position offthe'parts, the recess 21 inthe ring 20 will 7 be opposite the stud 18 so that said stud is 5. out of contact with the ring and the circuit to the lamp will be broken. If the driver wishes to signal that' he is tovstop or slow up, he "would push the v button 15 inwardly .and; thus 7 cause thejstud I8 to engage the recessed'part 10 of the ring 20- and thus close the circuit'to' the lamp, which would indicat eth-atthe car; 1. v I is to he stopped or checked. When either a i right or left hand turn is to be madegethei ope; v erator pushes upon the handle 13 in the prop 15 erdir-ection to move the spindlefi a quarter" turnso that the arrow will poin t in the direction'thevehicl-e is to turn'fThe detent 27 H s will hold the partsin adjusted position. As

the spindle is turn'ed', the'disk turns with V 9 itso' as tofcausea part of the di'skto contact thestud 18" and thus close the cireuit tofthe lamp to illuminate the arrow initsoperative I p positio 1 After the turn has been made, the "1 operator moves the cleviceto'its neutral po f sition, which will bring the recessed'partof 1 the/disk opposite thestu'd and thus break the circuit to the lamp;

V It .is thought from the foregoing descripv tion thatthe advantages an'd'novel; features of my invention will be readily apparent. he

c It, is tobe understood that Imay make changesin the construction and in the'com- "hinat-ion and arrangement of the several .parts',fprovi ded that such changes fall within T the scope of the'appendedclaim.
