April 15, 1 E. WEDEMEYER PYROPHORIC LIGHTER Filed Jan. 26, 1950 BY 4 1 4; 45 ATTORNE? Patented Apr. 15', 1952 PYROPI-IORIO LIGHTER Eric Wedemeyer, Floral Park, N. Y., assignor to Hamilton Art Metal Corporation, New York, N. Y., a corporation of New York Application January 26, 1950, Serial No. 140,610

4 Claims. (Cl. 674.1)

The present invention relates to improvements in pyrophoric table lighters or the like, having as an object the ease of disassembly for purposes of repair of broken or damaged parts, access to the fuel reservoir, replacement of liquid absorption material, and replacement of the Wick or pyrophoric elements as they wear out from constant usage.

It is quite common to have lighters in sections. However, the structures of this type of lighter heretofore have not provided the desired ease of assembly and in other ways have failed to meet the requirements of the art.

An object of the present invention is to provide a lighter assembly made of pie-fabricated sections arranged for ready assembly without requiring any great amount of skill.

A further object of my invention is the provision of an assembly of the type referred to above which will permit the removal of one or more sections from any part thereof without requiring the disassembly of the entire lighter.

Further objects of my invention will become apparent as the following description proceeds and are shown in the drawings, wherein:

Fig. 1 is a fragmental rear elevation of the upper portion of a lighter embodying the present invention;

Fig. 2 shows a side elevation of Fig. 1 enlarged and in exploded form, partly in side elevation and partly in cross-section;

Fig. 3 illustrates a fragmental plan section taken on its line 33 of Fig. 2;

Fig. 4 is a perspective view of the main mounting casting shown in the upper portion of Fig. 2;

Fig. 5 shows a fragmental side elevation on a smaller scale.

Referring now more particularly to the drawings, in which like parts have like reference characters, the device I0 comprises three main sections: a head or top portion I2 forming the lighter unit proper, a hollow intermediate or body portion I4, and a. hollow base or leg portion I6, said base portion It being apertured at its upper end as indicated at I8 to receive the fitted end 20 of the body portion I4 snugly andprovide an airtight seal against evaporation of the lighter fluid, said portions I4 and I6 being held in fixed relation by a countersunk screw 22 serving as a closure plug for the cavities in members I4 and I6.

Referring more specifically to Fig. 2, it will be seen that the hollow base portion I6 and the hollow body portion I4 cooperate to form a common reservoir 24 which is filled with the usual absorbent cotton 26 and wick 28, and in which the screw 22, when removed, provides an aligned aperture by which the reservoir is replenished.

As shown, the body portion I4 is hollow at its lower end as at 24' and has atits closed upper end an aperture 30 extending upwardly through the body portion I4, into which a wick holder 32 is firmly secured as by soldering, said holder 32 extending above the surface 34 of body portion I4. Body member I4 is provided at its surface 34 with a cavity or recess 36 to receive the tapered stem of the head portion I2.

Head portion I2 comprises a compact unit assembly which carries the conventional lighter mechanism generally indicated at 38, which mechanism, per se, forms no part of this invention. A support or bracket member 40, apertured at 42 and having a base portion 44, is adapted to slide easily over the upper part of the wick holder 32 in receptacle 33 and have its base 4 contact the surface 34, aforesaid recess 36 thus acting as a pilot hole for the tapered stem portion 45 of bracket 40. The lower portion 46 of the stem 45 fits into the lower part 46 of said recess 36 and is held therein by a set screw 48 in body portion I4, the upper part of said recess 36 being of a greater diameter to receive the conical coil spring 50 to be hereinafter described.

Bracket 40, referring more particularly to Fig. 4, is provided with a pair of lugs 52 having aligned openings 54 to receive horizontal pin 56, the ends of which fit into a snuffer cap member 58. Member 58 has an opening 53 in its front adapted to snap over and be held by a catch member 62 held between the bifurcated ends 64 of bracket 40. Catch member 62 is fulcrumed and resiliently braced by a U-shaped spring 66, one leg of which is fitted in groove 68 of bracket 40 and the other le in groove I0 of catch member 62; a second U-shaped spring 52 braced on bracket member 40 and coiled about pin 56 serves at its free ends to keep member 58 in open position while the lighter is in use.

A half-shell-like member 14 co-acting with member 58 has a flange or ring portion I6 at its lower end, having an over-sized aperture I8 which loosely encircles the upper part of stem 45, enabling said shell member I4 to rock rearwardly against the action of the spring 50 when so urged by contact with an arcuate flange on snufier member 58, when said closure is released from its fully closed position as seen in Fig. 5 to its open position as seen in Fig. 2. Member .14 is retarded from further rearward motionby an abutment 82 on body portion I4. Spring 50 is conical, its larger convolutions bearing on flange or annular portion 16 and its smaller and closely spaced convolutions being in tight frictional engagement with the shank portion 45.

As shown, the lighter mechanism 38 has the usual abradant wheel mounted to turn freely on the horizontal pin 55 which is supported by ears 52 and supports a fiat sprin pawl designed to disengage the stepped side surface of the abradant wheel when member 58 on which the pawl abuts is rotated counter-clockwise to its closed position. Upon release, snufier member 58 rotates clockwise, carrying with it the spring pawl and abradant wheel, said Wheel producing sparks from the pyrophoric element 84 which is carried in a vertical bore 86 which extends through the tapered shank 45. The pyrophoric element 84 is pressed upward into operative contact with the periphery of the abradant wheel by means of a compression spring 88, its tension being adjustable by a screw 99 threaded into bore 86 at its lower end.

Fig. shows the complete closure composed of snuffer cap 58 and shell member M in closed and inoperative position, wherein the rear edge of member 58 abuts the forward edge of member 14 in a plane 92. The abutting edges of both members have the same arcuate configuration and the case or housing formed by both members has a continuous surface. Abutment is retained by spring 50 until catch 62 is released by pressing thereon. Upward movement of member 14 is limited by contact of the forward portion of its flange 76 with an abutment 93 provided on bracket member 40.

It will be understood that the details described above need not be strictly adhered to and that various changes and modifications, all falling within the scope of the subjoined claims, may suggest themselves to anyone skilled in the art.

I claim:

1. A pyrophoric lighter comprising a body member having a hollow lower portion for receiving fuel, a cavity in said body member above said hollow portion, a slidably removable lighter unit comprising a bracket member having a vertical bore and a flint magazine in the form of a stem portion, the latter extending into said cavity, a tubular wick holder permanently connected with and extending upward from said body member and extending slidably through said bore and defining the horizontal position of said bracket member on said body member, catch means swingably connected with said bracket member, said lighter unit comprising closure means including two shell-like parts: a first part loosely rockably mounted on said stem portion and having an arcuate edge portion, a second part pivotally connected with said bracket member and comprising a snufier cap and means adapted to be engaged by said catch means for holding said second part in closed position, said second part having an arouate edge portion conforming with the arcuate edge portion of the first part, said edge portions abutting each other and said two parts forming a lid when said second part is engaged by said catch means, said second part pushing said firstpart out of its way and rocking it until overlapped thereby upon release of said catch means and opening or the lid.

2.
