United States Patent PYROPHORIC LIGHTER Alfred'Mosch, Jackson Heights, N. Y. Application September'22 1952, Serial No; 310,788 3 Claims. o1; 67-'-'7.1)f

The present invention relates to a pyrophoric' lighter; more p'a'rticularly'toa lighter comprising magazine means forstoringa plurality" of flints and adapted for transfer of-individual flints'from the magazine into operating position} to replace worn down flin'ts;

Conventional lighters carry only one flint, the. one which is in use. When this flint is exhausted, .anew flint must be inserted which" is usuallynot available'when needed.

It is an object of the invention to movably'ya'tta'ch a magazine member to the lighter casing, whichrnember has a plurality of cavities, each containinga spare flint; The magazine member can be moved .so that "its cavities are individually aligned with a tube in the 'lighter' ca'sing containing the" conventional spring urging'the'flint, which is in use, against an abradant wheel. Upon temporary removal of the spring, a. new flint can be transferred into the tube'fr'o'm a'cavityin the magazine member.

Further and other object'siofthe present invention will be: hereinafter set forth in the accompanying specification and claims, and shown in the drawings.which,.byway of illustration, show what I now consider to be preferred embodiments of myinventi'on;

Fi'gsi- 1 and "2illustra'te a lighter having a conventional abradant wheel 1 to which a flint 2 is urged'by means of a coil spring 3 inserted in a tube 7f which extends through" the fuel tank of the lighter. The lighter has a bottom portion 17 which is secured to the lighter body by screws 181 Spring 3" extends through portion 17 and is held therein by a screw plug 6; The inside of portion'l-T has a cylindrical cavity into which a cylindrical magazine member ordrum 19, shown separately and in larger scale in Figs. 3 and 4, is rotatably inserted. Member 19"has-al tnurled surface portion 20-which is accessible from the outside of portion 17. Member 19 has a plu r'ality-ofb'ores 21 placed in a circle coaxial of member 19; The center line of a bore in portion 17' through which spring 3- extends extends also through the aforemen= tionedcircle and isinlinewithone of the bores 21" when thedevice is in normal operating position. Ifplug" 6 and spring 3 are removed, member 19 can be revolved by manipulating thekn'urled surface portion 20 untila neWholbZT containing a new flint is inline'with tube 7". Thereupon the-new flint can be pushed into the tube and spring 3"" re inserted and held in position by' plug 6.

The modificationillustrated in Figs. 5 to 8' is suitable for storingparticularly long flints in a lighter; The cylindrical magazine member 22 shown separately in larger scale in Figs. 7 and 8 is rotatably inserted in casing? 23 extending from thebottom of'fueltank" 24into the latter. The magazine member has a flange 25 whose knurled rim is accessible from the outside for revolving member 22. The latter is held in the lighter body by a bottom plate 26 secured to the bottom of the lighter body by screws 27. In normal operation position, a coil spring 3" extends through one of a plurality of bores 28. arranged in member 22 in a circle coaxially of the member. The coil spring extends upwardly through a tube 7" in fuel tank 24 for pressing a flint 2' against abradant wheel 1. The spring is retained in the desired position by means of a screw plug 6. For insertion of a new flint into tube 7", the operation is the same as in the device shown in Figs. 1 to 4. Plug 6 and spring 3" are removed, permitting turning of member 22 by manipulation of flange 25 until a new flint is in line with tube 7".

Referring more particularly to Figs. 9 to 14 of the drawings, numeral 1 designates a spark-producing wheel of a lighter of the conventional type, against which wheel a flint 2 is urged by a spring 3. A trunk part 30 extends from the bottom of the lighter casing, around which trunk part extends an endless belt 4, shown in larger scale in Figs. 11 and 12. Belt 4 can be pushed around the trunk part 30 and is prevented from falling 011 the trunk part by means of a bottom plate 31 fixed to the trunk part 30 by screws 32. The inside of the belt has a plurality of grooves 5, a sleeve 5 shown in larger scale in Fig. 14 being placed in the bottom of each groove. Sleeves 5' are adapted to individually receive a spare flint. When a flint 2 is exhausted, spring 3 extending through one of the sleeves 5' and through guide tube 7 is removed, so that the magazine belt can be moved until a sleeve 5' containing a fresh flint is aligned with the guide tube 7. By re-inserting spring 3 and a plug 6 in plate 31 for retaining 3 spring 3, the new flint is pushed into position next to the wheel 1. If liquid fuel is used in the lighter, a filler screw 8 is removed for refueling.

In the modification illustrated in Figs. 15 to 18, the flints are stored in cavities 9 in a slide which is slidably attached to the bottom of the lighter casing. It is normally held in the position shown in Fig. 17, i. e. flush with the lighter casing, by means of coil spring 3 extending from tube 7 through a bore 9' in the left part of slide 10, bore 9' being closed by a screw plug 6. When a new flint is needed, plug 6 is removed, and the coil spring in tube 7 is withdrawn, whereupon the slide 10 is moved to the left as shown in Figs. and 16 until a cavity or pocket 9 containing a flint is in line with tube 7, so that a new flint can be transferred into tube 7. Thereupon the slide is pushed back into its original position on the bottom portion of the lighter body, the coil spring is inserted through bore 9 into tube 7, and plug 6 is inserted, holding the spring urging a flint against the abradant wheel 1 and thereby the slide 10 in place.

In the modification shown in Figs. 19 to 22, a disc 11 having radial recesses 12 individually containing a flint is used as storage member. The disc is received in a recess 13 in a lateral wall of the lighter casing so that the latter closes the radial recesses. The disc is rotatably secured to the lighter body by means of a screw 14 and a washer 15. When a new flint is needed, plug 6 is removed and spring 3 is pulled out of tube 7', whereupon wheel 11 can be turned until a recess 12 containing a new flint is adjacent to a slot 16 in the lower part of tube 7. The latter is laid in a groove in the recessed side wall of the lighter casing to which wheel 11 is attached. After transfer of a new flint into tube 7, the spring 3 is reinserted and plug 6 screwed into place. While I believe the above described embodiments of my invention to be preferred embodiments, I Wish it to be understood that I do not desire to be limited to the exact details of design and construction shown and described, for obvious modifications will occur to a person skilled in the art.

I claim:

1. A pyrophoric lighter having a casing containing fuel,

an abradant wheel supported by said casing, a tube extending through said casing and terminating adjacent to said wheel, a flint in said tube, a spring in said tube for urging said flint against said wheel, means extending from said casing and having a cross-sectional configuration similar to and smaller than that of said casing to form a recess extending around said casing, said tube having an end terminating in said casing at said recess, a flexible endless belt longitudinally movably received in said recess, said belt having a plane outside surface flush with the surface of said casing, the inside of said belt having a plurality of cavities adapted to individually receive a spare flint and to be individually aligned with said tube upon longitudinal movement of said belt.

2. A pyrophoric lighter having a casing containing fuel, an abradant wheel supported by said casing, a tube extending through said casing and terminating adjacent to said wheel, a flint in said tube, a spring in said tube for urging said flint against said wheel, means extending from said casing and having a cross-sectional configuration similar to and smaller than that of said casing to form a recess extending around said casing, said tube having an end terminating in said casing at said recess, a plurality of sleeves so placed in said recess as to afford rolling of said sleeves around said means extending from said casing, a spare flint in each of said sleeves, a flexible endless belt longitudinally movably placed around said sleeves for individually aligning said sleeves with said tube upon longitudinal movement of said belt.
