Specification of Letters Patent. Patented A11 g, 3 1915,

Application filed March 24, 1914. Serial No. 826,956,

To aZZ whom it may concern:

it known that l, CHARLES C. Prinz, a citizen of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented new and useful Improvements in Traflic-Indicators,

the indicating pointer to move to the rightor to the left according to the direction in which he intends to turn the machine.

Nith the above and other oh' cts in view,

el construcient of parts lolly descrihet,

n the accompanying drawingsr-ifigaie I is a front elevation of the tra'ziic indicator is invention, the some being hrol .1

to illustrate the contained niechani L 2 is a vertical diametrioal section (tor contemplated in this :e 1 which, in tile the invention, is nil provided with. a panel 3 of clear and front of -lof ground or c to difiuse the or other lamp case 1 and the case frosted gt rays of light 1' which is contained with located behind the Between the pan els 3 and *lis arranged an indicating pointer shown in it 1 form of an arrow the some being moun ed on she? 7 located centrally or the case 1 and journaled in the hack of the case and also in an L-shaped bracket 8. Fast on shaft 7 of the pointer 6 is a spur gear pinion 9 Whichmeshes with and is actuated by a toothed sector 10 pivotally mounted at 11 on the bracket 8. The sector 10 carries a double ended armature 12 at opposite ends of which are arranged electromagnets From one of the magnets 13 circuit Wires 1% lead through pos s 15 and 16 to a push button switch 1?. *rom the other electromagnet, Wires 18 lead through the post 1? and another post 19 to an additional push button switch 20. The switches 17 and 20 may be arranged on the dash of an automobile or other convenient supporting part of the machine, it being understood that the CllCUliS of the two electromagnets include a suitable source of electrical energy such as a magneto, battery or generator so that by pressing either one of the buttons 17 or 20 the appropriate electromagnet will be energized and therefore attract the armature l2 and consequently the sector 10 in a corresponding direction.

As indicated by full lines in Fig. 1, the

pointer 6 normally hangs pendant or vertically and when either one of the magnets is energized, the saidpointer is caused to swing to substantially horizontal position pointi ing eitherto the right or to the left as the may be as indicated by dotted lines in said figure.

llliile I have illustrated two push button itches l7 and 20 it Will of course be uno tood that a single switch may he employed in the form of the ordinary lever switch movable to one side or the other of ti? given point for the purpose of throwing into the circuit either one of the electroina y day light the pointer 6 will be Visible through the clear glass panel 3 at the front oi. the case while after dark the pointer 6 which is preferably of some opaquematerial will he clearly discernible in front of the panel l which as above stated is of ground or frosted glass or some equivalent 1naterial.

What I claim is A trafiic indicator for automobiles comprising a casing, a back plate therefor, :1 transparent panel forming a closure for the front of said casing, a ground glass panel located between said front panel and back plate, a shaft journaled in said ground glass panel and back plate, a p inter fast on said shaft, and actuating means for said shaft located between said back plate and ground glass panel and embodying a pinion having a fixed relation to said pointer and adapted to turn on the same axis there-With, a pendant oscillatory gravity centered toothed sector meshing with said pinion an arcuate armature carried directly by said sector and eoncentric to the axis thereof, nppositely In testimony whereof I aflix my signatu: located electromagnetsprranged at the 0pin presence of two witnesses. posite extremities of said armature, anelectrio lamp located between said back'plate CHARLES PRINZ' I i 5 and ground glass panel, and manually con- Witnesses:

'. trolled means for-independently energizing s H. PERKINS,

, said magnets. J. L. BRADLEY.
