ELECTRIC C IGAR LIGHTER Filed April 10, 1931 Patented Nev. 6, 1934- ELECTRIC CIGAR LIGHTER Sidney vL. Wolison, Meriden, Conn., assignor to The Cuno Engineering Corporation, Meriden, Conn., a corporation of Connecticut Application April 10, 1931, Serial No. 529,033 26 Claims. (01. 219-32) This invention relates to lighters for cigars, cigarettes, etc. of the type which are adapted to be heated on its support and thenreadily withdrawn from the electric supply connections for lighting a cigar, etc. V E

An object is to provide an inexpensive device oi this type in which the heater element is carried on the inner end of a removable member.

Another object is to provide such'a device which is of simple construction having an electric and heat insulating member serving as one of the bearing members for a slidable bearing during heating, removal and subsequent insertion.

Another object is to provide a device in which the igniter is housed and yet in which the glow of the igniter can be seen when it is heated.

Fig. 1 is a cross section of one embodiment of this invention.

Fig. 2 shows some of the parts before assembly.

Fig. 3 shows the heater element and some of the parts carried by the removable insulating socket member.

- Fig. 4 is a detail of the heater element support.

Referring to Fig. 1, some customary support such as the usual bracket 1 attached to the dashboard of an automobile carries a supporting plug' or tubular outer contact 3, which is secured thereto by the bent flange 2 fitting within and around a perforation in said bracket.

The outer end of said plug 3 is engaged by the wall or cup-shaped member or contact ring 4 slidable on the metal tube or sleeve 5. Also carried by the metal sleeve 5 is the removable metal base member 6 to which is clamped the heater coil or element 8' and its support or contact ring 9 by the stud or rivet 7. Yieldable interior contact member 10 is secured within the supporting plug as illustrated by means of the eyelet 11 passing through the disc 12 of insulating material such as fibre or a phenolic condensation product or a mixture'thereof with asbestos. Disc 12 is held between the wall 2' and the bead 3. The conducting lead 13 is secured as shown to the headed eyelet 11. I

Slidably bearing on the plug 3 is thesupportlng knob or socket member 14 preferably of insuiating material such as a phenolic condensation product or the like. As shown in Fig. 1, the right and of the metal sleeve 5 is closed by the glow window 15 ofeither transparent or translucent naterial held in place by the spun-over flange of ;he ferrule 16 to which is secured the socket and sleeve members 14 and 5.

The outer end 5' is flanged over to hold the ferrule 16 in place and to secure it in the socket or knob 14, the flange serving as an abutment. When the sleeve 4 is in place the fiangefi" is turned to prevent the parts from separating. The coil spring 17 is compressed between the flange 20 and the flange 4' so as to normally keep the socket member 14 and the lighter element flange 9 carried thereby out of contact and away from the yieldable contact member 10. An ornamental dash plate 18 may be secured to the plug in the manner illustrated. If desired yieldable retaining portions 19 may be stamped out from the sides 01! the plug 3 to assist in irictionally retaining the socket member in place, although if desired such may be eliminated.

The socket member 14 may have a sufflciently tight fit upon the plug 3 so that no such members 19 are needed, or if desired the engagement between the plug 3 and socket member 14 may be looser if the plug is mounted to extend in an upward direction so that gravity may hold the socket member in place.

The electric current enters through the conductor 13, thence to the yieldable contact members 10 and when the socket member 14 is pressed to the left, in Fig. 1, so as to close the circuit between the yieldable contacts 10 and the heater supporting cup or ring member 9, the current then flows through the heater.

From the center 01 the heater the current passes through the stud '7, unit base 6, sleeve 5. cup or wall member 4 to the plug 3 which is grounded to the i'rame of the car. When the heater element becomes incandescent its condition may be viewed through the glow window 15 and when hot enough the socket member may .be withdrawn. In withdrawing the socket member 14 the cup member 4 and spring 17 are carried by the sleeve 5 and the socket member 14 provides a convenient heat insulated grip or handle portion while the cigar or cigarette is being lighted from the heater element 8.

In assembling this lighter the insulating disc 12 carrying the yieldable contacts 10 is inserted into the plug 3 from the right end, as shown in Fig. 2, after which the flanges holding the disc in place may be bent up as illustrated in Fig. 1. The outer end of the plug 3 is then bent inwardly at 3' to provide an engagement for the cup 4 carried by the socket member 14.

. The heater element mounted within its supporting ring 9 is held in place by the stud 7 the insulating disc 21 therebetween. The portions of the members 9 and 6' which are contiguclamping the, members 9 and 6 to ether with ous the insulating disc 21 are not solid or imperforate but are either spoke-shaped or provided with perforations such as 9' as shown in Fig. 4 through which light from the. heater element is passed to permit the heater element to be viewed through the glow window 15. The insulated disc 21 must, of course, be of some translucent or transparent or perforated insulating material.

The unit base 6 is secured within the sleeve 5 by means of a yieldable horseshoe shaped detent or otherwise so as to permit the base 6 to be normally carried and movable with the sleeve 5 but permit removal thereof for renewal of the heater element when necessary.

In order to assemble the parts shown in Fig. 3 within the socket member 14, the sleeve 5 is first inserted in the socket member 14 from the left and the ferrule 16 inserted from the right. The outwardly bent flange 5 on the right end of the sleeve 5 may then be formed to secure the ferrule 16 in place, after which the glow window 15 can be inserted and the ferrule 16 bent down as illustrated at 16' to retain it in place. The spring 17 is next placed on the sleeve 5 and then the cup member 4 placed over the spring, after which the outwardly bent left end 5" of the sleeve 5 may be formed to retain the cup and spring permanently in place on the sleeve 5.

The wearing character of the socket member 14 is such that it may bear directly upon the supporting plugwithout the interposition of any metal wear resisting part being necessary.

One advantageous feature of the present construction is the location of the spring within the removable member so that it is spaced from the heater or resistance element and is located between the heaterand the forepart of the removable member. The engagement of the heater rim housing with an outwardly inclined contact 10 at substantially opposite locations is another movable therewith, a contact ring slidable on said tube and adapted to engage the tubular contact when the movable element is mounted on the stationary element, a spring interposed between the contact ring and a portion of the knob which is stationary with respect to the tube, and a heater element mechanically supported by said tube and having one end electrically connected to the tube, the other end of said heater element constituting a contact ring adapted to engage the contact in the stationary element.
