Application filed March 19, 192?. Serial No. 178343.

This invention relates to improvements in cigar and cigarette lighters, and has particular reference to a lighter of the pocket type.

An object of the invention is to provide an improved lighter of simple and practical construction wherein the elements constituting the ignition mechanism are compactly ar ranged and conveniently disposed, so that the operator may readily manipulate the device with one hand to cause the ignition ot the ignitable element and to extinguish the same.

Another object is to arrange the friction wheel or the ignition mechanism and the normally closed swinging cover for the ignitable element so as to rotate about a common axis, and to mount a releasing member for said wheel and cover concentric to said axis.

A further object resides in providing a releasing member which extends coincident to the axis of rotation of the friction wheel, and which is movable longitudinally of said axis to release said wheel so that it can rotate under the influence of a spring connected thereto.

The above and other objects will appear more clearly from the :tollowing description when talren in connection with the accoinpanying drawing, which illustrates a preterrcd embodiment oi the inventive idea.

in the drawing l is a perspective view of the lighter constructed in accordance with the invention and shown in its operated position;

llig. 2 is an enlarged top plan view thereof.

Fig. 3 is a vertical longitudinal section taken on the line 3-3 of Fig. 2.

l is a vertical transverse section taken on the line i l of Fig; 2.

5 is a section taken on the line 5-5 of Fig.

In its preferred form, the invention is shown as comprising a relatively flat casing 6 or" convenient size so that it may be carried in the pocket and which constitutes a fuel containing reservoir. The bottom 7 of the casing is provided with screw-threaded opening 8 in which plug 9 is removablymounted so that fuel may be poured into the casing when necessary.

lit will be understood, or course, that instead of simply having the liquid fuel in the casing, as indicated in Fig. 3, said casing may contain absorbent cotton or the like,

which becomes saturated with the fuel when the latter is poured through the opening 8.

The casing isfurther provided with a top closure 10, in which is removably mounted, adjacent one end. thereof, a holder 11 for retaining the upper end of an ignitable element 12, such as a wicl: usually employed for this purpose. The holder 11 projects exteriorly out of closure 10, so that the outer end of the wick 122 may be disposed and be ignited by the ignition mechanism presently to be describec.

Medially of the end oi the closure 10, the same also has mounted therein a tube 18, which projects downwardly into the casing with the outer or upper end of the tube er:- tending slightly beyond the closure. The tube is open at both ends, and its outer end is adapted to receive a pyrophoric element ll such as a flintor other suitable material capable of producing a sparlr. A constant outer pressure is maintained upon the element 14.- by means of the coil spring 15 Within the tube 13, the tension of said spring being regulated by screw 16 threaded into the inner end or the tube. The screw 16 is accessible for purposes of adjustment through the opening 8 in the bottom or the casing.

lhe top closure 10 also has secured thereto, by means of rivets 17, a supporting structure 18, the inner end of which, adjacent the center of the cover, terminates in two spaced dislrlike plates 19 and 20, the latter plate having a recess 21 in its outer face for a purpose which will presently appear. The centers of the two plates 19 and 29 are connected by a bushing 22, upon which is mounted, for to tation in both directions, a friction wheel 23. This wheel is of substantially the same diameter as the plates 19 and 20, and is provided on a portion ct its periphery with serrations 2st to term a roughened surface adaptedto contact with the outer end of the pyrophoric element l t, the serrations of the wheel being so disposed that when the latter is rotated in a clockwise -direction as viewed in Fig. 3, the rubbing of the wheel against the element is will produce a spark which will be deflected in the direction of the outer end of the wick 12 and thus ignite the same.

At a point on the wheel 28, when the same is in its normal position shown in Fig. 3

7 between the wickholder 11 and the tube 13, said wheel has secured thereto a swinging cover 25 in the form of an arm which is substantially a counterpart of the stationary support 18, and which is provided upon its inner surface with a recess 26 adapted to receive the outer end of the holder 11 and tit? I spark and uncovering the wick 12 so that it will be ignited may be produced in a single operation.

The means for rotating the friction wheel and cover 25 preferably comprises a convoluted spring 27 interposed between the wheel 24; and plate 20, the outer end of the spring 27 being fixed to-theclosure 1-0 while the inner end of said spring is provided with an extension 28 projecting into an opening formed in the friction wheel adjacent the center. When the friction wheel is in its normal position, the spring 27 is under tension, and upon release of the wheel, in the manner to be presently described, said spring expands and rapidly rotates the wheel to produce a rubbing contact with the element 14.

The means for retaining the friction Wheel and cover 25 in'normal position and for releasing said parts so as to permit of rotation thereof consists of a releasing member in the form of a pin 29 extending through the bushing 22 concentric to the axis of rotation of At the end of the pin" the friction wheel. 29, adjacent the plate 19, said pin has secured thereto a disk 30 which carries a locking pin 31 (Fig. 5) projecting inwardly through the plate 19, and having its inner end engage- "able with a recess 32 formed in the adjacent face of the friction wheel. I

When thus engaged with said wheel, the

pin 31 acts to prevent rotation of the wheel and cover. The opposite end of the pin 29 is formed with a head- 33 preferably countersunk within the recess 21 in the plate 20 and havin interposed therebetween and the bottom o saidrecess a coil spring 34 which normally exerts an outward pressure on the head 33 to retain the locking pin 32 in operative position. However, when the head 33 is depressed by the thumb to move the pin 29 and isk 3O laterally with respect to the friction wheel, or longitudinally of its axisof rota- .tion, it will be apparent that the pin 31 will As the friction wheel reaches its normal position, the recess 32 in said wheel will begin to come into alignment with the locking pin 31, whereupon the spring 34, which is then under tension, forces the pin 29 and disk 30 in the opposite direction from the movement previously described with the result that the locking pin 31 again enters the recess 32. It will, of course, be understood that the restoration of the friction wheel to normal position again places the spring 27 under'tension.

If desired, an additional or reserve pyrophoric element llmay be carried with the device by placing the same in asleeve 35, one end of. which is screw-threaded into the inner surface of the plug 9.
