Application, filed February 18, 1928. Serial No. 255,833.

r This invention relates to improvements in pyrophoric lighters of the pocket type in which is embodied novel means for making a spark and producing a flame.

An object of my invention is to provide a pocket sizcpgrrophoric lighter wherein is compactly cm died novel means for roducing a spark for the igniting of a wic Another object of my invention is to provide a pyrophoric lighter having the various operating parts thereof compactly contained in' a casing resembling a pen in 'shape.

Another object of my invention is to provide a combined cigarette holder,p(yrophoric lighter and pen, all bein embo ied in a convenient and compact orm suitable for carryin in a vest ocket.

Another object oi m invention is to provide a combined pyrop oric lighter and cigarette holder, embodying a construction which permits the convenient use of the lighter without its detachment from the cigarette holder.

Other objects more or less apparent will present themselves or will be specifically ,pointed out in the description to follow.

" In the accompan g drawings illustrating;the:preferred orm my invention may .assume: I

Fig. 1 is a side view of a'pyrophoric lighter and cigarette holder embodying my invention; Y

. Fig. 2 is a longitudinal sectional view of my improved "pyrophoric lighter taken on the line 2-2 0 Fig. 4;

Fig. 3 is a sectional view taken on the line 33 of Fig. 2; y

Fig. 4-is a sectional view taken on the line of Fig. 2;

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 2;

Fig.6 is a sectional view taken on the line 6-6 of Fig. 2; and

Fig. 7is, aside elevation of my improved pyrophoric lighter with a pen attached thereto, showing a part of the casing broken away and in cross section.

Referring to the drawings, the numeral 1 represents an oval shaped casing having a o detachable end piece 2 screwed into one end thereof and an enclosin end member 3 located at the other en Attached to the end member 3, as by screws 4, is a-circular shaped tubular member 5, which has one of its ends bent inwardly as at 6, and its oppo- -for the i iting of'the end 0 site end closed by a partition 7. An extension 8,- which forms a part of the tubular member 5, is provided with a large opening 9 in its side. Movably located at the end of the extension .8 is a cap piece 10 which is provided with a projecting part 11 that is movably located inside the said extension 8. The projecting part 11 is provided with a cut away part which forms an opening 12 of approximately the same size as the large opening 9 in the tubular member 5. Secured to the end member 3 and'to the partition 7, with its end extending beyond the latter, isa wick tube 13which carries a wick 14.' Also extending through the end member 3 and the partition 7 is a tubular member 15 having one of its ends closed and a pyrophoric bar 16 projecting from andbeyond its other end. A spiral spring 17 havin one end bearin against the closed end 0 the tubular mem r 15 and its other end pressing against the pyrophoric bar 16, serves to resiliently maintain the latter in an outwardly projectin position.

. Movably extending through the partition 7 and a tubular projection 18 located on the latter, is a pin 19 having a square end 20 which extends through a steel disc 21 and the cap piece 10. A screw 22, with its head located on the outside of the cap piece 10, is adapted to screw into the square end 20 of the pin 19, thereby providing suitable means for maintaining the steel disc 21 inside the cap piece. The pin 19 is formed with an enlarged central section which provides shoulders that are located against the steel disc 21 and the partition 7. A spiral spring 23 encircles the circular projection 18 and is secured at one end to the end of pin 19 and at its opposite end to the wick tube 13. The. steel disc 21 is provided with a plurality of small teeth 24 which contact with the end of the pyrophoric bar 16 and are adapted to co-operate with the latter to produce a spark the wick 14.

Movab y mounted on'the tubular member 5 and suitably held in position, as by projections-25, is a ring 26 which is provided with an inwardly extending projection 27 which passes through alslot located in the side of the tubular member 5.

,Movabl located inside a tubular projection 28 w ich is secured to the artition 7, is a bar 29 which is provided a jacent the projection 27 with a. pawl 30 and at its op- 110 posite end with a latch member 31which 15 located insideand adjacent the end of the rejecting part 11 of the cap piece 10. The atch member 31 is adapted to engage with turn the bar 29 so the latch member 31 may" be released from the projection 32.

As shown in Fig. 1, the casing 1 is slidably located in a tube 34 and the same is adapted to be pulled outwardly to light-a cigarette which maybe inserted in the end of a cigarette holder 35, the latter being attached to the tube 34 by bands 36.

The end piece 2 may be substituted'for a tubular extension 37 which is adapted to receive a pen or pencil 38. I 3

As illustrated on the drawings the lighter isin a closed position with the openings 9 and 12 closed, and the spiral spring 23 in a wound up position. To produce a spark for the igniting of the wick 14 and to bring into registration the'two large openings 9 and 12 respectively, in the extension 8 and projecting part 11, the ring 26 is turned by the hand so as to cause the extension 27 thereof to move the pawl 30. As the ring is turned and the pawl moved, the bar 29 is also turned. and the latch member 31 is released from the projection 32 of the projecting part 11. This then permits the pin 19, the cap piece 10, the steel disc 21 and the projecting part 11 to be turned by the spring 23 which is fastened at its ends to the pin 19 and to ,16, thereby producing a spar for the i ition of the wick 14. As the cap. 10 an its projecting part 11 are turned, the opening 12 in the latter is brought around to a position where it coincides with the opening 9 in the extension 8 of the tubular member 5. When the two openings are in this position the flame from the ignited wick 14 is allowed to pass therethrough for the lighting of a cigarette.

To close the openings '9 and 12, the cap piece 10 is turned in tie opposite direction to a position which causes the rejection 32 to engage with the latch mcm r 31." The turning of the cap piece in' this direction causes the spring 23 to again become contracted preparatory to the next lighting operation.

It is obvious to those skilled in the art that my improved pyrophoric lighter may be embodied in. other forms than the one shown and described herein, so for this and other reasons it is desired that my invention be included broadly within the spirit of the appended claims.

Having described my invention, what I claim is:

' -1. A pyrophoric lighter comprising a casing having a partition.member located therein and an opening located adjacent an end thereof, a wick projecting through the partitionmember, a pyrophoric element projecting from the partition member ad- .jacent the wick, a cap having an opening in its sides which is adapted to coincide with the opening in the casing, which said cap is pivotally attached by a pin to the partition member, a friction member secured to the cap and in contactwith the pyrophoric element, and a spring attached at one of its ends to the pin for rotating the cap, the pin and the friction member, whereby the friction meml *r may be moved against the pyrophoric eleinent to produce a spark for ignitingthe wick.

2. A pyroplioric lighter comprising a casing carrying a pyrophoric element and a wick, a cap pivotally attached hya pin to the casing, a friction member secured to the cap and in contact with the pyrophorie element, a spring attached to the pin which said spring may be compressed by turning the cap, mea'ns engageable withthe cap for maintainin the cap against rotation by the spring, ant means for actuating the first mentioned means, whereby the cap and the friction member may be rotated by the spring.

3. A pyrophoric lighter comprising a casing, a tubular member secured to the easing having an enclosing end men'lber, a wick projecting beyond the end member, a pyrophorie element projecting from the end member at a point adjacent the wick, a cap carrying a friction member pivotally atattached-to the end member, the friction member being in contact with the pyrophoric element, and a spring connected to the cap and the tubular member for rotating the cap and the friction member, whereby the friction member may bemoved against the pyrophoric element to produce a spark for igniting the 'wick.
