25 r energizing the Patented June 24, 1930 uN ITEosTA Es PATENT OFFICE MA'sAo HASEGAWA, OF SANTA ROSA, CALIFORNIA My invention CIRCUIT-CONTROLLING DEVICE Application filed June 30,

relates to improvements in direction indicators, and'it' consists in the combinations, constructions and arrangements hereinafter described and claimed.

'This invention is an improvement over the device shown in my co-pending application, Serial No. 177,076 filed March 21, 1927. In the co-pending application I set forth a pair ofswitches, which are held in operative position when' manually actuated, these "switches closing circuits to directionindi'c'ating lights and keeping the circuits closedso 'longas the front wheels of the car remain turned for causing the car to either turn t 'th6 [right or to the left. Special mechanism operatively connected to the steering mechanism is shown in my copendi'ng application for automatically opening the switches when the straightened out. a v

The present invention shows an improvefront wheels are ment in 'the' mechanism actuated by the steering" apparatus of the automobile.

, A further objectof my invention is to provide more simplified means ,for dema'gnets which hold the switches in operative position after they have once been moved. Thismeans is op- .er'ated when the wheels are straightened Other objects and advantages will appear as the specification proceeds, and the novel featureswill'be particularly pointed out in what I'hereinafter claim, i

My'invention is illustrated in the accompanying drawing forming a part of this application, in'which Figure 1 is a-schematic view showing th switche'selectrically connected to the signal lights" and the releasing mechanism; "Figure 2 is an enlarged view of the relea sing mechanism, a portion of the front wall'being'broken' away for clarity; and

section along the line3- -3 1928. Serial No. 289,372.

In carrying out my invention, I make use of an automobile indicated generally at 1. Upon the four fenders of the automobile I mount direction-indicating lights 22and 3-3 (see Figure 1). These lights are electrically connected to each other and to manually-controlled switches of a construction now to be described.

In Figure 1 I show a support 4 which may plates 13 and 14 when the push button 7 is depressed, hile the plate '10 contacts with plates 15 and 16. A wire 17 passes from the plate 14 and is wound around a magnet 18. In likenianner a wire 19 is passed around a magnet 20 and is connected to the terminal 15. "The wires 17 and 19 merge into a common wire 21 which leads to a binding post or terminal block 22 mounted in a release mechanism indicated generally at 23. The terminal 13 is connected to the lights 33 by'a wire 24, and in like manner the terminal 16 is connected to lights 22 by a wire 25. The lights 2-2 and 33 are grounded as at 26 and 27.

Referring to Figure 2', it will be noted that the binding post- 22 normally contacts with a conductor strip 28 carried by an arm 29, the latter being urged toward the binding post 22 by means of a spring'30. A wire 31 leads from the conductor strip 28 to a magnet 32, and the magnet is grounded at 33 for completing the electric circuit. A lever 34: is pivoted at 35 and swings independently of the arm 29. Thislever carries at its lower end an adjustable permanent to an L- hard steel m at 36 that is adapted to be attracted b t e magnet 32 when the latter is energize v The n per end of the lever 34 is pivoted haped arm 37 at 38'. This arm carries a spring hinge 39 which permits a trigger 40 to swing in one direction without afiecting the movement of the arm and which cannot swing in the opposite direction; and therefore a movement of this trigger in the latter direction will swing the arm. 'Ihe trgger 40 is positioned adjacent to a in cated generally M 441, and the tri jGClZIOllS' 42 forming a art of the drum.

The drum is rotatab y carried by the supporting plates 43 of the release 23. A ring44 tends to rotate'the drum in one direction. The drum hasan annulaigroove 45 for receiving a cable'46'. One end of.the cable is thedrnm the other end is passed by the to idler pulleys 47 and then connected to an arm 48. In Figure 1 I show the arm 48 as being connected by a link 49 to an arm 50 that forms a standard part of an automobile steering mechanism. It will hem-from this construction that a swinging of the arm 50 in either direction rotate the drum the foregoing in the same direction. and against the tenaionofthesri 44; p 118 description. of the parts of the device, the operation 'theneof may be readily understood. j

The push button 8 when w illuminates the signalson the side of the car, while the push button 7 illuminates the signals Assume the driver is going to turn to the righ He depresses push butten 8, which causes a current to flow from ahbattery 51 through wires 52 and 53 to the contact plate 10.

After the driver has'made the turn and starts to straighten out his car, the arm 50 is moved in theopposite direction and feeds slack into the cable 46. This permits the sprin 44 to rotate the drum 41 in a clockwise motion.
