Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed July 26, 1916, Serial lt'o. 111,414. 'Ztenewed @ctober 16, 1918. Serial No. 258,486.

To all whom it may concern- Be it known that I, For S. HANNA, a citizen of the United States, and a resident of St. Fetersburg, inthe county of Pinellas and State of Florida, have invented a certain new and useful Improvement in Steering- Wheel Control Means for Electrically-@perated Signals, of which the following is a specification.

One of the principal objects of the invention is to provide an improved means where by electrically operated signals carried on a motor car may be controlled and actuated without the necessity of the driver removing his hands from the steering wheel.

Another object of the invention contemplates an arrangement whereby the finger actuated blocks and associated parts may be readily dismounted at will to give access to the various switch devices "for purposes of cleaning and renewal.

A still further object resides in the arrangement of the blocks in such manner that they will not become accidentally depressed or shifted by reason of the drivers hands moving into various positions on the steering wheel.

A still further object of my invention is to provide an improved device of the character described, which will be extremely simple, durable, efiicient in operation, and inexpensive to manufacture- With these and other objects in view, the invention resides in the construction, combination, and arrangement parts hereinafter more fully described and claimed, and

illustrated in the accompanying drawings, in

which like characters of reference indicate like parts throughout the several figures, of which:

Figure 1 represents a view in perspective of a steering wheel signalcontrol device, constructed according to my invention, the electrical circuits being diagrammatically represented Fig. 2 represents a top plan view of a wheel, portions being broken away; i

Fig. 3 represents a side elevationai view partially in section of the steering wheel;

Fig. i represents a sectional view taken on the plane indicated by the line l% of Fig. 5 represents a sectional view taken transversely of one of the wheel spokes, on

the plane indicated by the line 55 of Fig. 2;

Fig. 6 represents a detail perspective view of one of the blocks and associated parts, the elements being shown in disconnected re: lation for the purpose of clearness in illustration;

Fig. 7 represents a view similar to Fig. 5 of a modified form of spoke.

The steering wheel 5 supports a separate contact or circuit closing device for each of the circuits employed in the signaling system, and since the construction in each instance is the same, a description of one will suiiice for all. This signaling system may include a number of direction indicating and stop signals of suitable construction, andin which the stop signal is included illustrates the operation of the device.

From a battery A suitably located on the car, extends a wire B to the stop signal C. This signal may be of ordinary construction well known in the art and need not therefore be described. Another wire D extends from the top signal and terminates at one of the tongues 9. A wire E leading from the opposite pole of the battery terminates at the other one of the pair of tongues 9. When the circuit is closed across these tongues 9, the stop signal will be actuated, and will remain in operation as long as this circuit remains closed. When the circuit is broken the signal will become inoperative.

In order that the wires which terminate at the tongues 9 may be properly housed and protected, the wheel is provided with a groove 10 and at the points where this roove passes the outer ends of the spokes 11 of the wheel, recesses or openings 12 are cut in the wheel which communicate with the groove 10. ihe outer ends of these openings 12 aline with channels 13 formed in the edges of the spokes 11, as indicated in Fig.

The wires D-E extend from the tongues 9 in opposite directions through the groove 10 and are then extended out through the closest openings 12 in the wheel, are led along the channels in the spokes which aline with these openings, and are then directed down through the outer casing of the steering wheel, as indicated by DE in Fig. 3.

As indicated in Fig. 7, the wheel spokes may if found preferable, be made hollow or formed with one or more internal channels be hereinafter described, and when in this position it will'be noted that the outer face of the block lies .inside of the inner surface or periphery of the steering wheel, so that the hands of the operator may be readily shiftedabout from place to place on the steering'wheel without danger of accidentally depressing the block.

On the inner face of the block is mounted .a metallic lug 17, which acts, when the block is pressed inwardly, to wedge between the tongues 9, thus closing the circuit across them and. actuating the signal. The block will be pressed in by a thumb or finger of the'driver, and when pressure is released'the block will again be forced outwardly whereby to open'the circuit.

A pair of leaf springs indicated at 18 is secured at their inner ends against the floor of recess 6 adjacent the ends of the latter,

. by suitable connecting means and the outer vided with slots 22 block is slipped instrument.

ends of these springs 18 bear against the inner face of block 13. The outer ends of the springs extend toward each other and the springs are suitablybent so as to normally retain the bloclsfin position for keeping the lug- 17 out of contact with the spring tongues 9. hThe springs are detachably connected wit the block by means of turn buttons 19 carried on shanks 20 whichshanks extend laterally through'theblocks and are provided with, screw heads .21 whereby they may be turned The outer. ends of the springs 18 are proof a width substantially equal to the width of the turn buttons 19, and in assembling the device after the springs have been secured in position, the

into the recess the turn buttons 19 being in alinement with each other and parallel with the slots 22 in the springs 18. Thereafter the shanks 210 are turned at The block is by a screw driver or allied.

yond the inner faceof the block so that the turn buttons will be positioned beyond the inner face of springs 18, whereby they may I be readily turned to lie transverselyof the springs. The slots 22 in the springs allow play of'the springs as the block is pushed inwardly or moved upwardly.

The block may be readily removed toallow access to the parts contained within the recess, by simply turnin the shanks 20 torealine the buttons 19 wit the slots 22 in the springs,"whereupon the block maybe manipulated to be'withdrawn from therecess. It will be understood from the foregoing that I-have provided a controlmeans which is characterized by great. convenience and ease of operation, and which presents an exceedingly simple construction, and while the device is capable of actuation without the necessity of loss of time by removal of the drivers hands from the steering wheel, yet, as already pointed out, there will be no danger of accidentallybringing anyof the signals'into operation. An advantage lies in the fact that the various elements of the device are concealed and hidden from view within the steering wheel, so that the finished appearance of the latter is not broken or marred;

Although I have described the preferred embodiment of. my invention, I may desire to make' such changes in the construction, combination, and arrangement of parts as do not depart from the spirit of the invention and the scope of the appended claims.

I claim:

g 1. In a signal control, a steering wheel having a recess therein and having a groove v for receiving wires, said groove communicating with openings leading to the surface of'the wheel, through which openings the wires are led, metallic spring tongues secured against the floor of therecess in s'pacedrelation to each other, said tongues forming terminals for the wires, a depressi ble block arranged in the recess and-having a metallic lug adapted to engage the tongues when the block is depressed for. closing the circuit across said tongues, leaf springs secured at their inner ends to. the floor of the recess, said springs at their outer ends bearing against the block, and means carried by 125 the block for detachably engaging said springs.
