The section 2l is grounded through its Contact with the sleeve i8. The case 7 is enlarged near the seat 6 so as to orm a chamber 42 in which is pivoted a lever 43,

as shown at 44, the long end of the lever extending into operative proximity to the plug 4 s0 as to be forced inwardly by the latter when the-same is seated while the other end of the lever carries in an insulating plug 46 and a Contact 47 adapted to be forced upon the periphery of the disl; 22 by means of a spring 48 when the plug 4 is removed from its seat and thereby allows the lever 43 to swing on its pivot. The contact 47 connects with a wire 49 which leads to any suitable source of energ such as a battery, the other terminal of which is grounded to complete the circuit.

The operation of my device is as follows:

The spring 34 tends to removethe drum formed of the two disks 2l and 22 so as to wind the cord 36 on the drum between the e1;- -tromities of the two disks, whereby the plug 4 is forced upon its seat 6 which is its normal position. The plug bears upon the long end of the lever 43 and thereby throws the Contact 47 away from the periphery oi' the disk 22 so that the circuit is broken. llhen the driver desires to give a signal by extending his left arm to project outside oi the body oi" the motor vehicle, he lirst grips the sleeve 2 of the lamp and causes the lamp to follow the motion of the arm so as to be visible to pedestrains or the drivers of other machines. In doing this he causes the cord 36 to unreel from the drum andplaces the spring 34 under tension while at the same timeV allowing the spring 48 to 'force the contact 47 upon the periphery of the disk 22 whereby the circuit is closed. Then the proper signal. has lbeen given, the driver draws back his .arm and allows the ,spring 34 to retract the lamp to its seat whichl causes the plug 4 to bear on the lever for disengaging the contact 47 from the periphery of the disk 22. Y

The electrical circuit is easily understood 'from thel drawing, the same comprising a source of energy such as a battery, the wire 49, the cont-act 47, the disl 22, the two wires 38 and 37 Connected to the .iilaments o1 the lamp, 'the second disk 1 9 and a ground Conncction between the latter and the battery.

I claim:

l. In a signaling device, `a casing formed with a seat structure upon the outside there of, a drum comprising two metallic cctions insulated from each other, a cord wound on the drum Comprising two wires connected to they two sections respectively,

a signaling element connected to the two wires and 'formed for seating in said seat, yielding means urging the element upon its seat, a lever pivoted in the casing having a contact at one end adapted to Contact with one oit the sections and extending with the other end thereof into thepath of the signaling element moving toward its seat for breaking the Contact.

2. In a signaling device, a casing comprising two sections, a` Central hub extending from one of the sections toward the other and `screw bearing on the latter` and threaded into the hub for lnildino` the sections together and a drum comprising a disc having a central portion depressed to iorrn a recess on vone side, and a cylinder i on the opposite side, and having` a central sleeve, extent 'from said depression adapted to revolve on 'the hub, a second 'fiat disc fastened to the depressed section, with insulating` material interposed between the discs7 a spring in the recess connecting the recessed disc to the heb, a cord wound on the cylinder between the peripheral portions of the discs, having two Iwiros connected to the two discs respectively, a seat formed in the casing, a signaling element. connected to the wires and adapted to be seated on said seat by the action of the spring and a contact lever pivoted in the casing and spring-actuated to normally `contact one of i 'the discs, and extending into the path oit' the signaling element moving toward its seat for breaking the Contact.

3. In a signaling device` a casing, split transversely to form two sections, and lieving axial means lioldingithe two sections together, a drum revolvable relative to the axial means having separable rim sections insulated from one another, wires wound on said drum and connected. to the drum scc tions respectively, a Vsignaling element connected to said wires. and spring means opposing unwinding of the wires 4. A reel for a signaling `device of the character described, gcoi'nprising a, disc formed with a central depression providing a recess on one side and a cylinder on the other side, a central sleevevextending from the depression, a flat disc perforated centrally to slip overthe sleeve, insulation intel`- posed between the discs and means for las toning one of the discs upon the other,

5. ln a signaling device, of the character described. a casing comprising two separable sections with axial means forlholding the same tog'gethc-irv` and a' drum comprising two separable sections insulated from one anotherrevolvable relative tothe axial moans, a spring arranged within the contines oi one of the drum sections, and a cord wound on the drum so as to place the spring under tension when the cord is unwound.
