POCKET LIGHTER.

Application mea July e, 1927, serial No.

Benzine pocket lighters have f become l known, in which the wick is covered by a is therefore possible to manipulate the pockethood, carried by a two-armed lever, which is oscillated at the same time as the friction'- vwheel is rotated. Ifthe free end of the twoarmed leveris depressed, the wick-hood mounted on the'other end of the lever islitted olf the wick, the friction wlleel rotates over a cerium-rod and sparks are thrown towards the wick. The oscillation caii'ied out bythe two-armed lever amounts to about 9 0". The free elld of the lever isidownwardly pressed by the linger, this presenting the following inconvenience. The finger loses its hold as soon as the corresponding lever-end is downwardly inclined and slips oill so tllat the last portion of the rotation of the frictionwheel is not carried through with the impulse required for the production of sparks. A pocket-lighter of this kind is not a one-hand pocket lighter, i. e. a pocket-lighter to be operated with one hand as, if the user grips the pocket-lighter so that the bottom-plate of the same rests on the index and middle linger of the hand, the thumb depressing tl'le lever-end, the pocket-lighter would drop fromthe hand at the moment when the inclination of the lever-end begins. He therefore must usethe otherhand for holding the pocket-lighterduring the depressing of the lever-end so that he cannot use his other handl for holding the cigarette or cigar to be lighted.

This inconvenience is absolutely avoided by the present invention, which consists in using foi-'the depressing of the lever-end a knob mounted on` a shaft, adapted yto be shifted in longitudinal direction in the body of the pocket-lighter inJ opposition -to the action of the spring, said nob-pressingfat the downward movement against the nose of the friction-wheel, so thatthe wickfhood'is lifted oi the wick and the friction-wheel rotated at the same time. l

The knob on the shaft is not inclinedbut shifted only in the longitudinal direction of the nger-pressure. The finger can therefore not slip off and it can be used at the same time-.for holding the pocket-lighter. It

lighter with one hand, the bottom plate of the pocket-lighter resting on the index and middle finger and the thumb of the same hand pressing down the knob. Dropping of the procket lighter from the hand is absolutelyA avoided so that the second hand is available for any'otlier manipulation. i

An embodiment of the invention is shown,

-by way of example, in'the accompanying drawing i inwhich Fig. 1 shows the improved pocket-lighter in side elevation and in closed position.

Fig. 2 is`a longitudinal section and Fig. 3 is a top planl view of Fig. 2. The 'casing ,l is closed atthe bottom by a plate 2 and at thet'op by a1 plate 'Ihre tubes 4 and 5 are fixed in the

plates

2 and 3 the tube 4 serving to guide a cerium! rod 6 and tube 5v serving to guide the hollow shaft 7 of the push-knob 16. The casing 1 has on the top plate 3 an extension 10 with holes 9 in its wall and serving as wind-screen,

said extension being normally closed bya lid 12, oscillatably mounted on an axle 11. On this axle 11 'a friction-wheel 15 having two

noses

13 and 14 is rotatably'mounted.

When the lid 12 is closed, the nose 13 of the friction-wheel 15 extends adjacent to the lower side of knob 16 the nose 14 bearing on the inner surface ,of the lid 12. When the knob 16 is depressed, in opposition to the action of a spring 17, the friction-wheel'l rotates about o in the direction of the arrow-line A (Fig. 2). The sparks which are thus produced, ignite the benzine in the free. end of a wick 18. Atthe same time as the friction-wheel. 15 is rotated, the lid 12 is oscillated so that the flame projectsfrom the wind-screen 10 which is now open at the top end.

On the inner end of the lid 1,2 a hood 19 forithe wick is fixed and a snap-spring 2O is lid 12 in the closing position, as said spring is clamped between the `inner surfaces of two opposite side walls of the wind-screen 1Q.l By this Ilocking of the lid 12 the spark-pro. duction is favored as, after the jamming has been overcome by the pressure exerted upon the knob 16, the friction-wheel 15 will rapidly rotate over the end of the ceriuin rod 6 under the influence of the knob 16 which is depressed without considerable resistance.

When the ceruim-rod 6 is no longer 15 it might happen that the lid 12 opensacpressed against the friction-wheel 7 by means of elastic arms 21 so cidentally in the pocket so that, asV the Wickhood 19 is no longer tightly pressed on the top-plate 3 of the bodyof the pocket-lighter benzine can evaporate. rIlhis must however be prevented in any position of the pocketlighter. For this purpose serves the spring 20 which securely holds thelid 12 in closed position, owing to the friction on the inner side of wall 25. A further advantage is that for opening the lid the resistance of'sprin'g 20 has to be overcome by a pressure on the push-knob 16. To open the lid a' strong pres sure has to be exerted on ythe knob 16. lf after the lid has been slightly lifted the frictional resistance of the spring 2O ceases, as it has come Out of Contact with the .Windscreen, the friction wheel 15 will be rapidly rotated by -the strong pressure onthe push knob 16 so that a strong jet of sparks is produced, this being necessary for the ignition of the benzine-gases coming from the wick 18. The spare cerium-rods 22 are stored inthe hollow shaft 7 ofknob 1G. The knob 16 is removably fixedin the upper'end of Shaft that it closes the top end of the magazine.

1in-.order to prevent excessive heating of the wind-screen 10 an inner wall 25 having air holes (Fig. 3) maybe arranged at a short distance from the outer wall of the windscreen.

The casing may be of any desired shape, size, material and ornamented or not.

l. A benzine pocket-lighter, comprising p moons;

said casing so that the edge of said knob standing above said noseof Said frictionwheel makes said friction-wl1eel rotate when that sparks.-

said knob is being depressed so are produced.

2. A benzine-pocket-lighter as specilied in claim 11 comprising in combination with the casing the push-knob the friction-wheel and `the ccrium-rod, a windscreen on the top plate of said casing, a horizontal axle journalled in said wind-screen and carrying said frictionwheel, a lid for said wind screen and fixed on said horizontal axle, a Wick in said casing the upper end of said wick project-ing into said Wind-screen, a wick-hood on the inner surface of said lid, and a blade-spring on the inner surface of said lid for securely holding said lid i-n the closing position.

A. benzine pocket lighter as specified in claim 1,'co1nprising in combination with a push knob, a hollow shaft of said push knob serving as magazine for Spare cerium rods, and elastic downwardly directed arms ixed on the lower surface of said push-knob and designed to hold said knob in said hollow shaft and serving as cover for said hollow shaft.
