AUTOMOBILE SIGNAL.

Application filed March a,

This invention relates to automobile signals, and more particularly to that class of signals which are worn on orattached to the arm, wrist or hand of the driver in order to show a light to cars in the rear when the driver throws out his hand. 7

One ofthe objects of the inventionis to provide a simple and effective device and apparatus of the saidcharacter, which is connected with a. source of. electric current on the automobile and has'spring means for reeling in the electric cable, and wherein the drivers hand when on the steering-wheel is relieved of pull through the-cable.

Another object is to provide a verysimple, inexpensive, easily applicable and removable device, to be worn on the back of the, hand, carrying the signal light. 7

A further object is to provide the simplest form of signal light with a very simple and convenient means for securing the same to a flexible device to be worn on the hand or'arm.

Other objects, features, aspects and combinations of, and embraced within, the invention will become apparent.

In the accompanying drawings, part hereof:

Fig.1 is a perspectiveview illustrating the invention installed in an automobile and connected with the drivers left hand; I

Fig. 2 is a plan view of thehandpart of the device spread out; and

Fig. 3 is a side sectional elevation of the part of the apparatus applied to the instrument board of the automobile,successive portions being broken away to show elements beneath. k i

The apparatus will be described in its preferred and complete embodiment.

A suitable casing 2 is applied by a 3 and clamping screw lto the loweredge of the instrument board 5 of the automobile. Secured in the side walls ofthis casing is a shaft or stationary axle 6. A spring case 7 forming is rotatable on-the axle, one end of the spiral reeling-in spring 8 being vconnected to the drum and the other end-to the axle.

United with the rotatable spring case is a cable drum 9 on which theelectric cable 10 is reeled and from reeled cable being retainedbetween the side of the spring case and a rotary disc 11, which is preferably of insulation, and whichis united with the drum and with'the spring case. Fixed to or formed with the disc 11,

disc entirely of insulation,

and rotatable therewith, is a disc 12, though these details maybe varied. a

The apparatus isconnected with a source of electric current on the automobile, to say, preferably with the starting and lighting system. i

A conductor 13 is shown leading from the positive pole of battery 14 to a binding post 15 on the casing 2. This binding post may be understood to be insulated. A resilientcontact arm 16 is pivoted on the axis of the binding post and is in electrical connection therewith. v I l 1 The disc 12 may havea spiral groove 17, like thegroove of a gramophone record, and such a groove serving'conveniently for controlling an automatic means for closing and opening the signalcircuit in accordance with the extent I mg means may be more special or mechanical than that shown, which is arranged in a simple manner by covering the outer part 18 of the grooved surface of the disc 12 with insulation, 01' by making this part of the while the inner part 191s of metal, or of metal uncovered by insulation. WVhen the contact point 20 of the arm 16 is in contact with the groove in the insulating, or insulated, part'lS, the circuit isopen, and when the point is in contact with the portion of the spiral groove in the part 19, the circuit is closed. The disc 12, or the metal part thereof, may be understood as in electrical connection with the case 2, which maybe suitably grounded as indicated.

The part worn by the driver comprises a fiat piece 21 of flexible material, of leather or similar suitable sheet material, cut in, such shape as to cover or to be worn on the and to leave the palm and that is to which the cable is drawn out or reeled in. The circuit opening and closcan be put on the bare-handor over a. glove with equal ease, and leave the hand free for steering on the wheel 42. I i

In the preferred form the part 21. is of form, greater in its trans- I It is cut or formed with a thumb hole 22 inone forward lateral region, or corner, and with a hole22 for the little finger in the. other forward lateral portion A strap 23 is secured at 2 1' I to one lateral rear portion of-the part 21, this strap having a series of holes 25 for buckling; and a? strap no i end 26 is lined to the other rear lateral corner region and has a buckle 27. This strap and buckle fastens the back hand cover and shield 21 about the base of the hand or the wrist. The palm and lingers are left entirely free for steering.

The cable 10 has one of its wires or conductors electrically connected at 28 with the drum 9, and throughthe drum 9 with the grounded casing 2. The end of the other wire of the cable is insulated from the grounded part of the device and is connected at 29 with the disc 12, or the metallic portion thereof.

The other end of the wires of the cable, which is of suitable length, say four or live feet, are electrically connected with an ordithat the lamp r against the piece 21, is

nary lamp socket 30. This lamp socket sin'r ply lies against the back or outer side of the flexible piece 21, in a general fore and aft direction, and is held thereto by simple means which will be described.

An incandescent lamp 231 is held in the socket by an ordinary detachable connection, the'bulb of this lamp lying against the forward part of the back of the flexible shield 21.

The socket 30 and the lamp 231 are secured to the flexible part 21 by a strap 32, which is looped over the socket and detachably tened, so as to clasp the'socket and lamp to the flexible piece 21, and to permit the ready removal of the socket. As illustrated, this strap is secured at one end, at 33, to the piece 21, and at the opposite side of the socket 20 it is passed beneath a retainer 8%, this retainer being formed by slitting or cutting the material of the piece at two regions 35, leaving the ends of the retainer united withthe material of the main piece. The end of the strap is fastened to the back of the piece 21 at a point, beyond the retainer by a snap fastener 36.

A means is thus provided for holding the socket and its light snugly against the back of the part- 21. No special or expensive littings, attachments, boxes, holders, lenses or the like are required- The bare bulb serves admirably for signaling purposes, and lying suliiciently safe from plan has also the advantage is exposed and readily removable from and replaceable in the socket, and that the socket, with or without the lamp, can be easily removed from the part 21. Vfith the parts assembled, the swell of the bulb 31 holds the lamp and the socket from being pulled out from beneath the strap 32. Vihat has been sought is simplicity and economy, with the maximum of convenience and effectiveness in use.

If the spring 8 were constantly pulling on the cord 10, the result would. be to impose a strain on the left hand of the driver when driving the car, which would be an annoyshocks. This ance and interfere with steering. This is overcome by the inclusion of an automatic catch or clutch 37 adapted to restrain the spring reeling mechanism at substantially any point, and to permit itself to be disengaged by a pull on the cable so that the cable may be reeled in when desired. The catch is pivoted on the rotary spring case 7 and is adapted to engage a notch in the stationary axle.

v The insulated or non-conducting portion 18 of the spirally grooved disc 12, and the un insulated orconducting portion 19 thereof, are of such relative radial widths that when the cord is drawn to a distance and there held by the catch allowing the drivers left hand complete freedom in steering, the circuit is not closed and the lamp 31 is not lighted. When, however, the driver throws out his hand to signal to trafiic in rear, the cable 10 is unreeled further, rotating the cable drum and the disc 12, so that the contact point 20 passes into the conducting portion of the groove 17, causing the circuit to be completed When the hand is.

and the lamp to flow. returned to the steering-wheel, the cable=is reeled in sufliciently to cause the lampto be extinguished again, so that it does not shine in the drivers eyes. Another form of switch or circuit controlling device serving the-same purpose may be employed.

When the device is not in use it is reeled in to the casing 2, where the rear end of the lamp socket 30 may be received within a tubular part 38 fixed to the casing, through which tubular part thecord emerges.

While the preferred embodiment of the in .vention has been described in detail, it will be understood that there changes in form, detail and that parts of the invention may be used without others.
