LIGHTER Application filed September 8, 1927. Serial No. 218,168.

This invention relates to lighters of the Vtype wherein a toothed Wheel abrades a pyrophoric member and throws sparks on to a suitable wick for igniting the wick. In those lighters which have been previously designed to ne carried in the pocket, the wheel has most frequently been operatedeither automatically by means of springs after the wheel oper ating mechanism has been manually released, or the wheel has been manually operated directly as bymeans of the thumb. The automatically operated lighters, however, are open to the objection that the normally locked operating mechanism may be unintentionally or accidentally released, in the pocket, as by coming into contact with articles carried in the pocket or with the material o-f the pocket itself, with consequent danger of setting fire to the pocket. Those lighters having a manually operated Wheel are objectionable for the reason that the thumb or linger used for turning the wheel is readily soiled thereby and sometimes abraded and injured. In both types of lighters, the wick flame is readily extinguished by a slight air movement, draft or breeze.

My invention is designed to provide a lighter in which the wick flame is protected, the wheel automatically operated only when the lock mechanism therefor is designedly released, and in which the other objections above set forth are met.

The various objects of my invention will be clear from the description which follows, and from the drawings, in which, f

Fig. 1 is a front view of my improved lighter, showing the parts in the locked positions thereof.

Fig. 2 is a vertical section of the same, showing the parts in the positions assumed thereby after the wheel has been operated to strike a light.

Fig. 3 is a top plan View of the lighter shown in Fig. 1. 1

Fig. 4 is a bottom plan view of the same.

Fig. 5 is a front view of a modified form of locking catch particularly adapted to prevent accidental release thereof, and I Fig. 6 is a vertical section of part of the lighter showing a modified form of the wheel operating mechanism, whereby the Wheel is rotated in one direction only.

In that practical embodiment of my invention which I have illustrated herein, the casing. 10 is made of suitable size and shape to fit easily into the pocket of the user, and is designed to hold inflammable liquid 11 therein, such as benzine, alcohol or the like, or to hold absorbent material soaked with such liquid. The wick bushing 12, adapted to hold the wick 9, is removably maintained in place in theupper end 13 of the casing as by means of a threaded connection therewith, or a tight fit., or in any other suitable manner which will suggest itself to those skilled in the art. An extending flange 14 may be provided on the bushing 12 for forming' a leakproof joint with the casing as will be described more fully hereinafter. By making the wick holder removable, the difficulty heretofore experienced when trying to insert a wick into the holder is obviated. It has heretofore beencustomary to compress the wick downwardly into the holder therefor, pushing the entire length of the wick through the holder. With my improved construction, the wick holder may be removed entirely, after whichV only the upper end of the wick is pushed up through the opening in the holder until that end projects slightly through the holder. The depending portion of the wick need then only be iiiserted into the casing and the bushing replaced. Adjustment of the wick is effected before securing the parts together by pulling either on the projecting upper end or on the lower end, it being understood that the wick being of soft material is much more easily arranged in position by pulling thereon than by attempting-to force it through an opening by compression. Replacement of the wick by the user when it has been burnt out may also be effected rapidlyT and easily in the same manner `without the necessity for using special tools for that purpose.

A flint cylinder 15 of the usual typeis supported in the flint holding tube 16, which is inclined sufiiciently' to bring the upper end of the flint in the proper position relatively to the toothed spark producing Wheel 17 and to bring the lower end l8of the tube near the tube I6 and bearing on the flint 15 serves to maintain said flint at all times in ressed engagement with the sparking wheel 1 The lower end ofthe tube 16 may be threaded to receive the spring adjusting screw 21, though it is obvious that said screw may be dispensed with if desired, and the lower end of the sprin allowed to rest directl against the head g2 of the screw plug 19, w ich normally conceals said screw and said s ring. The casing is replenished with li u1d by removing the plug 19 turning the lig ter u slde down, and pourin liqui in through t e openm therefor. ,l t w1ll be seen that removal o said plu also exposes the adjusting screw 21, so that t e pressure'on the flint may be adjusted at the same time, if desired. For 1nsurin a leak roof 'oint between the casing and t e plug, pre er to arrange a suitable washer as 23 between the head 22 of the plug and the bottom of the casing.

The device for automatically operating the toothed spark roducin wheel 17 will now be described. aid whee is loosely or lixedly mounted as may be found preferable, on the shaft 24 and is 'ven its rotative movement through the me ium of the swinging wheel cover 25 which is also mounted on said shaft. The shaft 24 passes through the sides 26 of said cover and is su ported in the upstandin sides 27 of the wic shield 28. One end o the coil spring 29, mounted on the shaft 24,

may engage the cover 25 while the other end may en age the shield 28, as shown, Figs. 2 and 6 though it will be understoo that the ends of the spring may be otherwise arranged, provided only that movement of the cover toward locked position winds u or stresses said spring, and movement o the cover toward the released position thereof (Fig. 2),allows the spring to unwind itself.

In that form of the wheel mounting illustrated in Fig. 2, the circumferential surface i ofthe wheel is inv close contact, with the inner faces of the cover 25, whereby the wheel teeth engage the cover and the wheel is prevented from moving relatively thereto. In this construction, movement of the cover causes corresponding movement of the wheel. In the form illustrated in Fig. 6, however, the wheel is mounted on the shaft 24 inde endently of the cover and may move inde en entl therewhich urges the ball toward the narrow part of the s ace 31 and into engagement with the wheesteeth. When the cover is rotated in a counter clockwise direction, as viewed in the various figures, the ball is jammed between the wheel and the cover in the narrow part of the space 31 and causes both to rotate together. When, however, the cover is rotatedy in a clockwise direction, .the ball tends to slip over the wheel teeth and to remain nearer the upper part of the space 31 and does not therefore operatively connect the cover and the wheel together, whereby movement of the cover does not effect movement of the wheel. The spring 32 is preferably used to insure the action above described thoughkit may be dis ensed with if the space 31 is properly shapedi It will be understood .that while I have shown one form of operative ball clutch, for the urpose mentioned, I do not wish to be limite to said form since any other suitable types of such clutch may Ibe used instead.

the parts, the bottom edge of the cap, which rotates together with the cover 25, en ages the upper surface of the iiange 14 angl excludes air from the wick thereby extinguishing the wick Hame. The cam rod 35 which controls th'e movement of the wheel, is secured to and protects the cap 33, and is suitably curved and constricted at its free end to form the cam 36. Suitably fastened to the top 13 of the casing is the grooved post 37, in the groove 38 of which is pivoted the trigger catch 39 as on the shaft 40, said trigger being protected and substantially enclosed y said post. When the cam rod 35 is depressed, the cam 36 engages the hook end 41 of the trigger catch which extends slightly outside of the post, and forces said catch to rotate out of t e ay of the cam about the shaft`40 and agaiii/vst the action of the compression spring 42.

Said spring normally acts on the arm 43 of the trigger catch for urging said catch toward the locking position thereof, so that after the cam 36 has passed the hook end 4l, said end engages the flat upper side of the cam rod and maintains lsaid rod in the locked position thereof. A suitable lug as 44 may be provided on the trigger catch for preventing the spring 42 from rotating said catch too far. The arm 43 extends but slightly outside of the post 37 and does not present a projection long enough to be accidentally operated. If desired, the arm 43 mayv terminate in the slightly projectingv finger piece 45, which, when depressed, removes the hook end 4l from the cam rod and allows the coil spring 29 to rotate the rod together with the wick cap, the wheel coverand wheel, with a rapid movement, whereby the wheel strikes sparks from the flint and ignites the wick. When the rod and the parts connected thereto are rotated in the opposite direction, the wick cap extinguishes the wick flame, the spring 29 is put under stress or wound up ready to lift the rod 35 when it is again released, andthe rod is locked in place by th trigger catch. f

As indicated in Fig.v 5, the arm 43 of the catch ma be dispensed with to obviate all danger o said arm being accidentally or unintentionally operated, and the catch may instead be formed with a serrated curved surface 46 of substantial length designed to be i rotated by the thumb, and extending but slightly outside of the post 37. There'being no decided projections on this `form of catch, there is no danger whatever that it may accidentally be unlocked.

In order to enable the user to use the lighter in a breeze, I provide the wick shield 28, held to the casing top 13 by the wick bushing 12, or soldered or otherwise secured thereto as by suitable screws or rivets. An

, opening 47 may be provided in one end of the shield to allow the passage of the rod 35, the other end of the shield being left open if desired, to receive the wheel cover 25 or that end may be partly closed, the top of the shield being open. For supplying air to the wick,

- window openings 48 are provided formed by pressing part of the material L19of the shield outwardly or inwardly as may be preferred, provided that the window material 49 is inclined 1n `such a manner as to direct the air entering the shield upwardly toward the top of the flame so that the flame canont be extinguished by the entering air. To prevent leakage of liquid into the shield and about the wick holder, a suitable washer similar to the washer 23 may be interposed between the fiange 14 of the wick holder and the base of I the shield.

It will be seen that I have provided an improved lighter well adapted to operate under the severe conditions of practical use and for the .purposes for which it is intended. I do not intend to be understood, however, as limiting myself to the specific structures shown and described, since variousl changes in the illustrated embodiments of my invention may be made without departing from the-spirit and scope thereofor from the range of equivalents afforded by the appended claims.
