T 0 all "a; an it may concern:

Be it sown that I, Joint G. Coos, a cit-izen of United States, residing at Brookty of Kings, State of New York, have in rented certain new and useful lnr provemcuts in Electric lgniters, of whicl'i the following is a full, clear, and exact description.

My irr'ention relates to improrements in. electric iiters, and has for its objectto provide an igniter in which a resistance at the end of an automatically reeling cable heated tor the purpose of igniting or burning, anil is automatically cutout of circuit when the cable is released.

An object of my invention, in its preferred form, is to provide an igniter which is connected to the circuit through a reel on which a cable containing the conductors is automatically wound by a spring, and in which the circuit will be automatically closed when the cable is unreeled, as well as automatically opened when the cable is released.

The following is a thes'cription of an embodiment of my invention, reference being had to the accompanying drawings, in which- Figure 1 shows in side elevation a cigar lighter embodying my invention. Fig. 2 shows the same partly in end elevation and with the reel in section. Fig. 3 shows a detail of the automatic circuit controller of Fig. 1. Fig. 4 shows an enlarged detail of the cable leading to the igniter glowcr. Fig. 5 is a diagram of circuits. Fig. 6 shows a modification partly in diagram.

Referring more particularly to the drawings, 1 is a base, 2 is a metallic standard. connected thereto, 3 is a reel mounted on a bearing l secured to the standard 2 by the screw 5. v

6 is the winding spring connected to the reel at '7 and to the bearing at 8. This spring, while conventionally shown, may be of any ordinary form suitable for causing the reel to revolve.

9 is a contact mounted on the reel and separated therefrom by insulation 10, A brush 11 secured to the upper end of the frame makes contact with this contact 9 so as to maintain an electrical connection therewith as the reel is revolved. The upper portion of the brush 11 is provided with a contact point 11.

\Vound upon the reel a cable 1'9, having two

flexible conductors

20 and 21 separated from one another by insulation 22 The outer surface of the cable is provided with a metallic helix 23, which preferably,

although not necessarily, is in electrical contact with the flexible conductor 21 so as to reduce the resistance 0 the circuit formed by the conductors of the cable to a minimum. One end of the conductor 20 passes through an insulating bushing 24 in the side of the reel 3, and is connected to the cont-act 9. The corresponding end of the conductor L1 is electrically connected to the body of the reel The reel 3, together 10c with the bearing 4 and frame 2, being of metal, the end of the conductor 21, which is connected to the reel, is thus electrically connected with the binding post- 'lS, while the end of the conductor 20, which is connected with the contact 9, will be connected to the insulated brush 11, so that when the spring 13 is moved into engagement with the contact 11, the end of the conductor 20,

which is connected with the Contact 9, will .08 electr cally connected to the binding postli'. At the outer end of the cable 19 a resistance carrier 25, insulated from the conductor 20, is provided, within which a the ends of the

conductors

20 and 21 are connected to a resistance 26, this resistance being any suitable form of electric glower used for cigar lighters, such, for instance, as a small coil of high resistance platinum 19 wire.

The outer end of the spring 14: is provided with a notch or opening 27, and above this opening is provided a circular guide 28, which, when the spring 6 winds the cable 15 upon the reel, guides the carrier 25, which ferring to this diagram and also to the other figures, it will be seen that the carrier 25 may, on account of its flexible cable, be carried from point to point within a radius 25 of several feet, and that whenever it, is

moved so as to unwind the cable, the spring 13- is brought into engagement with the contact 11, so that a circuit is formed from the battery 29 connected to the binding post 112' so through the spring '13, brush 11, contact-9,

conductor 20, resistance 26, conductor21, reel 3, support 2, to binding post 18, and back to battery 29. The parts of this circuit, with the exception'of the resistance 26,

being of low resistance, the battery current is sufficient to heat the resistance 26 to an igniting heat. When the carrier 25' is released, the cable assing through the guide 28 is automatical y wound upon the reel 3' 40 by the spring 6 until the carrier 25 passes" partially through the guide-28 and engages the outer end of the spring 14:, forcing it downward so as'to permit t me contact 13 to separate from the cont/act 11, thus automati- -.t5 cally openin, the battery circuit. The mere movement 0 the carrier necessary for lightmg, therefore, automatlcally completes the circuit, and upon the release of the carrier the circuit is automatically interrupted by the action of the winding spring through the cable 19, the cable'at the same time being wound up so as to be stored in very compact form. I

In a modified form, a normally open switch 30 is provided in the carrier, having contacts forced into engagement by a pushbutton 31, in which case the brush 11 may be permanently connected to the binding post 17 in" any suitable manner, as shown in Fig.

7 6O 6 where the control of the circuit is effected entirely through the switch 30. In this construction, also, the circuit is automatically opened when the cable is manually released.

While the embodiment shown in Figs. 1

to 5 is the preferred embodiment of my inincense.
