Referring more particularly to the drawings and to the novel illustrative embodiment therein shown, the present invention comprehends a novel lighter 19 of the type employing a gaseous fuel such as butane or liquefied petroleum gas stored within a container or fuel cartridge 11 containing a solid adsorbent 12 for the fuel. This adsorbent which substantially fills the container or cartridge 11, preferably comprises a mass of extruded, calcined fullers earth, of the type obtained in Georgia and Florida, adapted to adsorb and store a liquefied petroleum gas such as butane. Other solid adsorbents which may be employed include bentonites and particularly diatomite bentonite.

The lighter comprises a substantially rectangular frame or housing 13 having an opening for the reception of the cartridge 11 and the frame or housing including a head 14, side walls 15 and a base 16. The frame and cartridge are adapted to be received in an encompassing or outer casing or enclosure 17 of plastic or other suitable material. To facilitate removal of the frame 13 and contained cartridge 11 from the casing or housing 17, the base of the latter is slotted at 13 to permit the insertion of a coin or other instrument to force the frame and cartridge from the casing. The cartridge may be of metal, plastic or other suitable material adapted to receive and retain the adsorbent 12 and the contained or stored liquefied petroleum gas under relatively high pressure without any appreciable distortion of the container or fuel cartridge 11 by the internal pressure.

The head 14 of the frame 13 is divided or arranged in two sections, an upstanding part 19 made or formed integral with or rigidly aflixed to the upper end of the frame and a separate part 21 detachable or removable with respect to the part 19, but adapted to be joined by a screw or other attaching means at 29. Each of these parts 19 and 21 is cored to provide complementary cavities for receiving operating or actuating mechanism for proper functioning of the lighter (Figs. 5, 7, 8, 9, 11, 12 and 16). As clearly disclosed, in these complementary recesses or cavities are arranged a pair of spaced and depending operating levers 22, 22 suitably afiixed at their upper ends to a depressibie or thumb-actuated cap or cover 23 formed as an inverted cupped member having depending walls. The rear wall 24 is outwardly flared or curved so that as the cap is depressed it pivots out.- Wardly and downwardly (see Figs. 8 and 9) With this outwardly flared rear wall adapted to overlap the upstanding ends 25 of the sections 19 and 21. To facilitate such movements, these ends are preferably relieved or rounded at 26.

The operating levers 22, 22 are each provided with an arcuate slot 27 with these slots aligned and adapted to receivea transverse pin 23 having one end thereof suitably mounted in the side wall of the section 19 (Figs. 7, 8, 9 and-l6). The forwardly or outwardly extending projection 29 of each lever is reduced and curved and with these projections adapted to carry or move in a vertical bore 30 a burner nozzle or gas flow control .31 to control the operation of a valve unit 32 for a fuel burner 33 at the upper end of the nozzle or flow controller 31. This is accomplished by locating each of these'projections 29 adjacent their end 34 within an annular recess or groove 35 in and disposed intermediate the ends of the nozzle or gas flow control 31 and each projection, adjacent the end 34 where it engages a shoulder 36 defining the base of the groove 35 of the nozzle or flow controller, having a cam surface 37 engaging the shoulder 36 and thereby depressing this nozzle or flow controller 31 to actuate the valve 32. A cross pin 38 connects the extreme ends 34 of these spaced projections and retains these ends in the groove 35.

In addition to lowering the nozzle or flow controller 31 to open the valve 32 and permit the escape of the gaseous fuel from the fuel supply cartridge 11, through the hollow core or passageway 39 in the nozzle or flow controller 31 to be ignited at the burner opening 41, the levers 22, 22 (Figs. 7, 8 and 9) are each provided with a cam surface 42 bearing against a roller 43 carried by a cross pin 44. This pin and its roller are carried by the upper end of a pair of spaced links 45, the other or lower end of each link being pivotally mounted and adapted to be rocked about a rock shaft 46. Pivotally mounted on one end of the cross pin 44 adjacent a link 45 is one end of a connecting rod or bar 47, with the other end of this rod or bar having an eye 48 adapted to receive a lug or projection 49 on a pawl driver 51. Thus by depressing the thumb-actuated cap 23, the nozzle or flow controller 31 is depressed to open the valve 32 and permit the escape of gas, and the cam surface 42 on the operating levers 22 simultaneously retracts the connecting rod or bar 47 which oscillates the pawl driver 51 through a desired arc of movement in a counter-clockwise direction. Upon release of the cap or thumb-actuated pad 23, the rocking links 45 and the roller 43 are springbiased to their forward position by a spring 52 wound about the rock shaft 46 and having one end 53 engaging a pin or projection 54 on a link or arm 45 and the other end 55 hearing against the upstanding end Wall at 56 of the head 14 (Figs. 7 and 8).

The pawl driver 51 is of cup shape having the projection 49 and a projection 57 substantially 180 apart, the latter adapted to be received Within a peripheral slot 58 in a disc 59 (Fig. 10). This disc which is carried with the pawl driver on the pin or shaft 60 has a substantially radially extending drive pawl or tooth 61 adapted to engage one of the ratchet teeth 62 on the adjacent face of a spark wheel 63, and thereby rotates in but one direction the abrasive surface of the spark wheel over an adjacent flint 64 to thereby project sparks over the burner opening 41. Upon release of the thumb-actuated pad or cap 23, the connecting rod or bar 47 is returned to its forward and inoperative position (Fig. 8), and such movement causes the roller 43 to ride over the cam surface 42 and elevate the levers 22 to their raised position.

The valve unit of assembly 32 for the liquefied gaseous fuel is carried by the fuel cartridge 11 (Figs. 6, 8 and 15). It comprises a cup-shaped housing 65 depending into the top wall 66 of the outer casing of the cartridge 11 with a peripheral shoulder 67 seating upon the exterior of the upper wall. It is internally threaded to telescopically receive an externally threaded, inverted cupshaped housing 68 which housings 65 and 68 combine to form a valve chamber. The housing 65 is provided with a small gas orifice or aperture 69 in its base aligned with similar orifices or apertures in an outer valve disc 71 and a cupped member 72. The member 72 conformably receives a gas flow restriction disc 73 formed of a filter paper or material adapted to filter out any of the solid particlesof the adsorbent as well as any foreign matter, This restriction disc 73 is maintained within the hollow of the cupped member 72 by means of an apertured inner valve disc 74 formed of a deformable metal or material having an upstanding boss 74* over which is placed a compression spring 75. One end of this spring 75 seats on the peripheral flange of the cupped member 72 and the other end against the base or bottom disc of a vertically movable valve member 76 to spring-bias this valve member to elevated, closed position. I

The valve member 76 is provided with a valve stem or burner core 77 projecting through and above an aperture or orifice 78 in the upper housing 68, with the end of the stem or core 77 aligned with an opening in a flexible or resilient gas seal cap 79 of rubber or the like seating upon the peripheral shoulder 67 of the lower housing 65 of the valve unit. To seal the gas against escape from the interior of this housing assembly, an O-ring or toroidal sealing ring 81 is carried upon the upper face of the disc of the valve member 76 whereby when the latter is in its elevated position, the sealing ring 81 seats against the underside of thetop wall "of the upper housing 68 and seals the escape of gas through its aperture or orifice 78 and through the aperture or opening in the gas seal cap 79 from where it escapes through the bore or passageway 39 in the nozzle or gas flow control 31. This cap 79 being of rubber or resilient material, seals against the base or underside of the nozzle or gas flow control 31 when the parts are in assembled relation.

To accommodate this cap 79, the underside of the stationary section or part 19 and the removable section or part 21 of the head 14 is recessed to conformably receive this cap when the cartridge 11 is inserted into the frame 13. Embossments 82 on the base 16 of the frame are adapted to be received and retained in complementary recesses or detents in the base of the cartridge case. When the nozzle or gas flow control 31 is depressed by the projecting ends 29 of the operating levers 22, the valve stem 77 being of grcaterwidth than the diameter of the passage or bore 39, is engaged and depressed to thereby open the valve 76 and allow the gas entering the passage 39 to escape.

The flint 64 is carried in a recess or cavity 84 of a flint holder 85. The base of this holder is slotted laterally or transversely at 85 to receive a flint control 86 in the form of a cross having a horizontal arm 87 engaging against the underside of the flint 64 anda depending vertical arm 88 which is s ring-biased to elevated position by a coil spring 89 whereby it exerts pressure against the underside of the flint and forces it against the spark wheel 63. The flint holder 85 is slidably mounted in transverse aligned slots in the fixed part 19 and Within removable or detachable part 21 of the head 14 of the frame 13 (Figs. ll, l2, l and 16).

The outer end of the flint holder 85 is provided with lateral projections 90 and the inner end is reduced at 91 and provided with lateral projections 92. The projections 90 are adapted to be received in complementary notches 93 in the fixed part 19 of the head "14 and in similar disposed notches in a side wall of a cap 94 covering the spark wheel 63 and associated parts, wherebythe cap 94 is locked in assembled position by the projections 90 in the notches 93. The cap is provided with an opening 94 for the flame of the burner. The flint holder may be withdrawn sufliciently either to remove thecap-94 or to allow access to the flint 64, but provision is made to prevent its complete withdrawl as shown in Fig. 16. This is accomplished by providing the adjacent walls of the fixed part 19 and removable part 21 with tracks 95 which stop short to provide stops or shoulders 96 against which the projections contact at the limit of withdrawal of the flint holder.

A flint control lock 97 in the form of an angular locking plate having an upstanding flange98 at its outer end and side flanges 99 and 101, is slidably mounted in the tracks 95 formed by the transverse slots in the fixed and r movable parts 19 and 21, respectively, of the head 14. Theflangc 101 is provided with an upstanding projection 102 providing a stop and limiting the movement of this locking plate to the length of the relatively short slot into which it projects and in which it moves (see Fig. 16), thereby preventing the complete withdrawal of the control lock 97'.

To permit the flint holder to be withdrawn to the limit of its outward movement as in Figs. 5, '14 and 16, the horizontal arm 8'7 of the flint control 86 is de-- ressed sufliciently to withdraw it from its slot 85*, whereupon applying inward pressure to the outer flange 98 of the lock 97 causes the latter to abut and force the holder 85 outwardly sutlicient to permit the operator to grasp the outer end of this holder by the lateral projections and withdraw it to the osition shown in Figs. 5 and 16. Such inner movement of the control lock 97 moves it to a position over the upper edge of the boil z'ontal arm 87 of the flint control 86 and retains this arm out of the slot 85 and depressed against the tension of the coil spring 89 (Figs. l1, l4 and 16), thereby per= inittin ready removal of the flint holder 85. With= drawal of the flint holder 85 also releases the cap 94 so that the latter may be lifted for access to the s ark wheel 63 and associated parts. 7

When the flint 64 has been replaced, the flint holder 85 may be quickly returned to its operative position by merely forcing it inwardly from the positions shown in Figs. 11 and 16 to the osition shown in Fi 12. In this movement, the flint holder 85 engages or abuts the flint control lock 97 and moves the latter from its position over the upper arm 87 of the flint control 86 (Fig. 11) to disengage this arm and permit it to be received and elevated into the slot $5 of the flint holder 85 by the spring 89 (Fig. 12). In this position the flint 64 is tcnsionally held against the spark wheel 63. A flint tube 103 receives the lower end of the coil spring 89 and the vertical leg 88 of the flint control 86.

From the above description and the disclosure in the drawings, it will be readily evident that the resent ln= vention comprehends a novel cigarette and cigar lighter of the pocket type employing butane or a liquefied petro= leum as which expands into a gas when released to the atmosphere. This fuel is stored within a novel pressure type fuel storage receptacle or cartridge containing an adsorbent of solid particles and dispensed ina novel man nor to enhance the operative life of the li hter before the cartridge or fuel storage unit re uires replacement or re-filling.
