, -12 claims.

The invention relates to lighters and, with regard to its more specific features, to catalytic action lighters.

One object of the invention is to provide a pocket lighter which can be operated with one hand and which can be used in a gale of wind to light a cigarette. Another object of the invention is to provide a reliable and efllcient catalytic lighter. Another object of the invention is to provide a catalytic lighter which may be operated in the same manner as an automatic pyrophorlc lighter. Another object of the invention is to provide a catalytic action lighter having a large reserve of fuel. Other objects will be in part obvious and in part pointed out hereinafter.,

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exempliiied in the structure to be hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing, in which is shown one ofvarious possiblef embodiments of the mechanical features ofthis invention. Figure 1 is a. side elevation of a lighter con-v structed in accordance with'the invention;

Figure 2 is a vertical sectional view of the lighter;

Figure 3 is a horizontal cross-sectional view taken on a line 3-3 of Figure 2: and

Figure 4 is a plan view of the lighter.

Similar reference characters refer to similar.'

parts throughout the several views of the draw- Ing.

` Referring first to Figure 1, I provide a fuel receptacle III in which may be inserted cotton Illa or other suitable absorbent for the retention of a liquid fuel, for example a-hydrocarbon fuel. As better'shown in Figure 2 the fuel receptacle I3 may be formed by joining together a pair of struck shells Il to form side and end walls, the side and end walls being closed by a top wall I2 and a bottom wall I3. In the bottom wall I3 is a the inside of the fuel receptacle In by a hole I9. i Thus air can enter the fuel receptacle III, but

neither air nor vapor can escape therefrom by way of the cap I4. Preferably a washer 2U is provided between the bottom of the wall I3 and the upper side of the closure cap I4 to eliminate leakage at this point.

In the top wall I2 of the lighter is an orifice 2| in which fits a flanged cylinder 22 having a ting bore 3l in a cylinder head 32 whichis screw l5 threaded in order that it may be secured inthe cylinder z2. There is a. ho1e 33 1n' the side of the cylinder 22 just under the top wall I2 and there.-

is an annular groove 34 in the cylinder head 32 which registers with this hole 33. Comparing now Figures 2 and 3, the cylinder head 32 has a bore 35 extending inwardly'from the groove 34 which meets a bore 36 extending upwardly from the bottom of the cylinder head. rI'hrough the cylinder head 321s another bore 3l which extends from the top to the bottom of the cylinder head. v

A leather washer 33 having a hole for the pas- .sage of the piston rod 23 without interference therewith is adapted to close both bores 33 and 3i. The leather washer 33 may be secured to the under side of the cylinder head 32 by means of a rivet 33.

Downward movement of the piston 33 forces whatever is in the cylinder 22 outwardly through a pipe I3 connected to the closed bottom end of the cylinder 22. At the same time the washer 33, which acts as a ap Valve, is Withdrawn from the bores 33 and 3'I allowing air to enter the cylinder 22 on the upper side of the piston 23 and allowing vaporzed fuel to enter through the hole 33, annular groove 33, bore 33, and bore 33. 'The relative sizes of the bore 3l on the one hand, and the bores 33, 35, and 33 on the other hand, regulate the mixture taken into the cylinder 22. Upward movement of thepiston 24 .forces by pneumatic pressure the washer 33 against the bores 33 and 31, whereupon the mixture on the upper side of the piston 24 passes to the lower side thereof by action of the cup shaped piece of leather 25. By reason of the fact that the gas is sealed in the upper side of the cylinder there isvvery. little tendency to suck air or `anything else through the pipe it upon upward movement of the piston 24.

Piston 24 is operated through the piston rod 28 by means of a finger piece member 4| secured to the top of the rod 28. This finger piece mem ber may comprise a flat member 42 secured in place by a head screw 43 which screws into the piston rod 28. f

Extending upwardly from the top wall i 2 of the lighter are a pair of ears 44. Extending between the ears 44 is a shaft 45 screw threaded on one end to fit in corresponding screw threads in one of the ears 44, there being a suitable flange on the shaft to keep it from loosening once it is secured in place. Journaled on the shaft 45 is a snuffer member 46 which comprises a top portion 41 having a pair `of downwardly extending sides 48, 48 fitting inside the ears 44, 44 and through which the shaft 45 passes. On the front end of the top .portions 41 and on the under side thereof is secured a snufer cap 48.

The fiat portion 42 of the finger piece member '4| is bent over at the front part 50 thereof to ger piece member 4| and the sriuiier member 46.

When the finger piece 4I is depressed the snuifer member 46 is turned to raise the snufier cap 48.

The snuffer cap seats firmly against an annular seat 52 of a flange 53 provided on a tubular member 54. Tubular member 54 has a cylindrical chamber 55 in the bottom of which is an opening 56. The bottom part of the opening 56 is screw threaded and receives one end of the pipe 40.

The cylindrical chamber 55 receives a catalytic member 51 which may be formed of a composition of platinum black and some porous ceramic material or the like, being in the form of a plug fitl ting the chamber 55 and preferably having a centrai bore 58 therein. Removably securing the catalytic member 51 in place is an annular cap 59 which has resilient sides having one or more inwardly pressed portions 60 to snap in place into a groove 6i in the member 54. The member 54 passes through and is secured to the top wall I2 forming a tight seal therewith. l

When the parts are in the position shown in the figures, fuel issealed in the fuel receptacle I0 as all openings are closed. Depression of the finger piece 4I, however, raises the snuffer cap 49 and at the same time forces a mixture of hydrocarbon vapor and air through the pipe 40 into the cylindrical chamber 55 and thus into the catalytic action member 51. This causes the member 51 to heat up and glow, whereupon a cigarette or cigar or the like may be lighted by merely placing the end of it against the member 51 and drawing in air.

It will thus be seen that there has been provided by this invention an apparatus in which the various objects hereinbefore set forth, together with many practicaladvantages, are successfully achieved. l
