CIGAR-LIGHTER AND THE LIKE.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed May 13, 1915. Serial No. 27,751.

To all whom it may concern:

Be it known that I, JOHN G. Coox, a citizen of the United States, residin at Brooklyn, Kings county, State of ew York, have invented oer-Iain new and useful Improvements in Cigar-Lighters and the like, of which the following is a full, clear, and exact description.

My invention relates to cigar lighters, illuminating devices, and the like, and has for its object to provide a device having a reistance element which can be drawn out for a suitable distance, and when the resistance is drawn out will automatically close an electric circuit, and when released w1ll automatically open such circuit.

It further has for its object to provide a fuse in series with a resistance element of an igniting or illuminating device.

It further has for its object to provide a new and improved resistance carrier.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which F igure 1 is a plan view of a cigar lighter embodying my invention. Fig. 2 is a side section. Fig. 3 is a vertical section of the same on the line 3-3 of Fig. 1. Fig. 4 is a diagram of circuits. .Fig. 5 is a perspective view of the resistance and its carrier. Fig. 6 is a perspective view of the fuse and its carrier. Fig. 7 is a sectional view showing a modified form of an embodiment of my invention.

Referring more particularly to the drawv in s 1 is a face late which is adapted to be secured to the dashboard of an automobile or other suitable support and forms a portion of the base for the operating parts. 2 and 3 are supporting plates connected thereto, and together with the plate 1, constituting the base of the apparatus, the plate 2 being of insulating material, such as fiber, and the plate 3 being of meta 4 is a drum supported by the plate 3- to which the inner end of a spring 5 is connected.

6 is a reel carrying a coiled cable 7. The outer end of thesprin 5 is connected to the reel 6, as shown in ig. 1. Within the reel is an insulating bushing 8. Within this bushing is a tubular sleeve 9, and within this sleeve is another insulating bushing 10 having a solid end 11 which passes through a hole in the drum 4 and constitutes a trunnion for the reel. Within the bushing 10 is a metallic rod 12 one end of which passes through the plate 2 and constitutes the other trunnion for the reel- The cable 7 has two conductors, one of which is electrically connected to the sleeve 9 and the other ofwhich is electrically connected to the member 12, as shown in Fig. 3.

13 is a contact brush carried by the plate 2 and having its free end bearing upon the shoulder formed on the sleeve 9.

14 is a binding post connected to the brush 13.

15' is a contact brush bearing upon the end of the rod 12 and carrying at its upper end a transversely extending spring arm 16 which terminates in a. contact 17 tending to make engagement with a stationary contact 18 to which a second binding post 19 is connected. The brush 15 is secured to the plate 2 by screws 20.

The cable 7 at a point near its outer end is provided with an enlargement 21 to which is connected a socket 22 having a screw threaded metallic lining 23 and an axial terminal contact 24.

25 is a fuse carrier consisting of a sleeve having a screw threaded portion 26 which engages with the screw threaded lining 23 of the socket. This screw threaded portion 26 is provided with a flange 27. Mounted upon this flange is an insulating ring 28 on which is mounted a circular contact plate 29.

30 is a fuse connecting the contact 29 with the flange 27 and passing through a recess in the insulating portion 28.

31 is a resistance carrier made of insulating material and having a terminal 32 axially located at its inner end for engaging the contact 24:. The resistance carrier has undercut projections 33. 34 is a. resistance wound upon these projections so as to traverse the face of the resistance carrier, and

end of the resistance is connected to a con-.

tact 35 beneath the head of the resistance carrier and adapted to engage the circular plate 29.

36 is a cap screwing onto the socket 22 and covering the sides of the resistance carrier and the fuse carrier.

40 is a soft rubber ring which acts as a cushion whenthe socket is released so as to drop.

The electrical connections are shown dia grammatically in Fig. 4, in which 37 is a battery or other source of current.

The operation of the device is as follows: In use the socket 22 is pulled outwardly so as to unwind the cable '7 against the action of the spring 5. ,As soon as the enlargement 21 is withdrawn from the spring-arm 16 the contact 17 is brought into engagement with the contact 18 completing the circuit from the battery 37 through the resistance 34. The spring arm tends to move, in a direction at right angles to, the axis of the portion of .the cable adjacent thereto.' The resistance may be used for ignition purposes such as for lightin a cigar or for illuminating purposes. When the socket 22 is released the spring 5 rewinds the cable drawing the socket into the position shown in Figs. 1 and 2;Whereupon the cable with its enlargement 21 engages the spring-arm 16 so as to withdraw the contact 17 carried thereby from engagement with the contact 18 automatically opening the circuit through thei-resistance.

The fuse '27 in the fuse carrier 25 is in series with the resistance 34 and if the battery current is too strong or kept on too long a period will-melt so as to open the circuit at that point. The fuse carrier is an inexpensive element and can be easily replaced. The resistance carrier is also an in expensive elementand can be easily manufactured. I e

In Fig. 4 a'modification of the device is shown in which the enlargement on the cable is shown at 21 and ,is separated from the socket 22 by a flexible portion 38. In this case, when the socket is released the enlargement 21 actuates the contact 17 and the socket itself hangs in a vertical position,

this being permitted by the flexible portion 38. In order to hold the hanging socket stationary, I provide a clip 39 carried by p the face plate 1, which is adapted to-receive the socket and into which it can be easily snapped.

As will be evident to those skilled in the art, my invention permits of various modicarrien awaeva I fications without departing. from the spirit thereof or the scope of the appended claims.

What I claim is: -1. The combination of a drum with a cable thereon, a spring normally tending to revolve said drum so as to wind up said cable, a spring member carrying a contact and tending to move toward said cable in a direction substantiallv at right angles to the portion of the cable adjacent thereto and moved in the other direction by the lateral engagement therewith of said cable when fullv Wound), and a, contact engaged by said movable contact when said cable is unwound.

2. The combination of a .drum with a cable thereon, a spring normally tending to revolve said drum so as to wind up said cable, a spring member carrying a contact 7 and tending to move toward said cable in a direction substantially at right angles to the axis of the portion of the cable adjacent thereto, and a stationary contact engaged by said movable contact when said cable is gagement with said screw threaded sleeve and said fuse carrier, and a resistance upon said resistance carrier one end'of which is connected to an axially located terminal on said resistance carrier, and the other .end of which is connected to a terminal adapted to engage with the contact plate on the fuse 4. A resistance carrier having a head and a resistance element on the front surface of said head, a shank of lesser diameter projecting from-the rear of said head, a contact axially located on the end of said shank, a contact on the flange formed by the reverse side of said head between the periphery thereof and said shank, said contacts being connected with the terminals of said resistance.

5. A resistance carrier having a head formed with a recessed face and with a circumferential groove in its periphery, said groove and said recessed face forming between them a flange, said flange having a series 'of interruptions dividing the same into undercut projections, a shank for said head, a conducting sleeve thereon, a terminal at the-end of'said shank and a resist anoe wound on said projections and having its terminals connected electrically to said transversely to the axis of said conductor at sleeve and to said contact respectively. the portion thereof to which it is ad'acent 6.
