Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now more particularly to Figure 3,

I provide a casing which desirably consists of a pair of shells suitably fastened together as by 0 solder, the dividing line between the shells (which is scarcely discernible in the finished article) being indicated by the dotted line 2| in Figure l. The casingy 20 is closed at the bottom by a bottom wall 22 which has four orifices 23, 24, 25 and 13 26. The orifice 23 has secured in it, desirably by solder, the lower end of a tube 21. Likewise the orifices 24, 25 and 29 have secured inthem tubes 28, 29 and 30 respectively. The bottom of each tube is closed by a threaded screw plug, 20 these plugs being designated by the reference characters 3|, 32, 33 and 34 respectively for the tubes 21, 28, 29 and 30.

Referring now to Figures 3 and 4, the top of the casing 20 is closed by a top wall flange 35 25 which may be secured to the casing 2li by solder. The tube 21 extends through the top wall flange 35, the tube being located near one end of the lighter as shown in the drawings, and having an integral flange 39 with a seat 31 for a snuifer 30 cap 39 which will be hereinafter more fully described. The tube 29 containsa spring 39 the upper end of which is coiled about the shank of a plunger 40 engaging a piece 4I of pyrophoric metal or other substance adapted to produce sparks. Referring particularly to Figure 3, the bottom end of the spring 39 is coiled about the knob 42 formed on the upper end of the screw plug 32. By unscrewing the plug 32 the spring 39, the plunger and the pyrophoric metal 4| 40 may be removed from the tube 28 at any time for the purpose, fr example, of replacing aggused piece of pyrophoric metal with a fresh piece.

Referring now to Figure 3, extending downwardly from one end of the top wall flange 35 45 and soldered to the inside of the casing 20 is an irregular supporting member 43. The tube 29 extends through and is supported by the member 43, and the upper end of the tube 28 is supported by a platform 44 extending inwardly from 50 the flange 35.

yReferringnow to Figures 1 and 2, desirably formed integral with the member 43 are a pair of upwardly extending side members 45, 45. Extending between these side members and near `the front thereof, as better shown in Figure 1, is a shaft 46 one end of which is threaded and also shouldered, and the other end of which has a slot therein for ascrew driver. Both the threaded and unthreaded ends of the shaft 46 60 position relative to the entire mechanism being fit in holes, threaded and unthreaded respectively, inthe side members 46, 45.

Referring now to Figure 3, journaled on the shaft 46 so as to be freely rotatable thereon is an abrasive wheel 41 which desirably has teeth 68 resembling ratchet teeth. The abrasive wheel 41 is in contact with the upper end of the pyrophoric metal 4| which is urgedagainst the teeth 48 by means of the spring 39; when the abrasive wheel is rotated in a clockwise direction as viewed in Figure 3, portions of the pyrophoric metal 4| are torn from the body thereof and form a shower of sparks directed to the left in said figure.

Referring now to Figures 2, 3, 6 and 7, there are likewise freely journaled on the shaft 46 a pair of fiat side arms 49, 49 forming the forward part of a finger piece member 56. This finger piece member is shown in perspective in Figure 7 and consists of the aforesaid fiat side arms 49, 49 joined together by skirt portions 5| and a back 52, the arms, the skirt portions and the back being desirably an integral piece. Resting on the top of the skirt portions 5| and the back 52 is a finger engaging portion 53 which may be fastened to the said skirt and back portion as by soldering. This finger engaging portion 53 closes over part of the space between the two skirt portions 5| and the back Wall 52. Referring now to Figure 3, a member 54 is secured to the inside of the skirt portions 5|, 5| and the nger portion 53, and all these parts together with the back 52 form a closure 55 for a spring 56. The bottom of the spring 56 fits in a tube 51 held by the irregular supporting member 43, while a rod 58 desirably fits inside the spring 56 extending at least part way up in it in order to prevent said spring from collapsing. It will thus be seen that the spring 56 maintains finger piece 56 in the position shown in Figures 1 and 3, but that said finger piece may be readily depressed to the positions shown in Figures 5 and 6 by pressure on the portion 53. The front ends of the arms 49, 49 are provided with holes 59, 59 through which the shaft 46 passes, and when the finger portion 53 is depressed the entire finger piece 50 swings downwardly about the shaft 46 as a pivot.

On the front of the nearest arm, Figure 1, is a downwardly extending lug 66 the purpose of which will be hereinafter explained. Opposite each other in the arms 49, 49 are a pair of arcuate slots 6|, 6|, the curve of which is drawn on a radius extending from the pivot shaft 46, and through the slots 6| extends a shaft 62, like the shaft `46, which is supported by the side members 45, 45 and extends between them, its

clearly indicated in Figure 1. Upon the shaft 62 is pivotaily mounted a snuffer member 63 which carries the snuifer cap 38.

Referring now to Figures 4, 5 and 7, extending inwardly from one of the skirt portions 5| is a latch operating projection 64. 'I'his projection 64 may be formed by forcing inwardly part of the metal which constitutes the skirt 5|, a. cutaway portion 65 being indicated in Figure 4 and representing that part of the skirt portion 5| from which the metal forming the projection 64 was deflected. In this manner manufacture of the complete finger piece 50 is facilitated. Rei ferring to Figure '1, extending inwardly from the arm 49 which is integral with the skirt portion 5| having the projection 64 is an integral lug portion 66 the purpose of which will be hereinafter explained. This lug portion 66 'is made by upset ting the metal inwardly.

'Ihe snuffer member 63 hereinbefore referred to is shown in perspective in Figure 8 and in different operating positions in the other figures. It comprises a top portion 61 merging into a pair of downwardly extending side portions 68, 68 at one end, and side portions 69, 69 merging into a rounded downwardly extending front portion 16 at the other end. The side portions 68, 68 of the snuifer member flt between the side portions 49, 49 and the skirts 5|, 5| of the finger piece member 56, and the shaft 62 has journaled thereon a sleeve 1| which passes through opposite holes in the sides 68, 66, the sleeve 1| being preferably secured in place by any suitable closed position as shown in Figure 3. The portion to be operated 14 is engaged by the under side'of the finger engaging portion 53 when the finger piece 50 is moved downwardly. Prior to the moving downwardly of the finger piece 50 a projection 15 formed integral with the portion 53 and extending forwardly therefrom is in engagement with the under side of the top p0rtion 61 of the finger piece. Under these conditions the spring 12 has no effect upon the snuffer member 63, as whatever couple is exerted by its end 13 is balanced by the couple exerted by the other end 14, through the medium of the projection 15, or in some cases an intermediate portion of the spring 12 may actually be in engagement with the under side of thevtop portion 61. The moment the projection 15'is removed from the under side of the top portion 61, however, as by moving the finger piece downwardly to the position shown in Figure 5, the tension of the spring 12 is exerted against the snuffer member 63 to swing it upwardly. Thereupon the snuffer member 63 does move upwardly to the position shown in Figure 5 being held there by latch means which will be presently described until the linger piece 50 is moved all the way down, whereupon the latch is tripped and the snuifer flies upward to the positionshown in Figure 6.

'I'he lighter of the present invention is adapted l to burn solid fuel in the form of a stick of fuel 16 which is received in the tube 21 and urged upwardly by means of a spring 11. 'Ihe composition of this solid fuel is not the subject of the present application and any fuel which can be ignited by pyrophoric sparks may be used. The tube 30 contains a spare stick of fuel 18 which may be inserted in the tube 21 when the stick 16 is consumed. 'I'he snuffer cap 38 is received and held by the snuier member 63 and has a lower bevel edge 19 which seats upon the seat 31 to prevent evaporation of the fuel. The pawl member 92 nts between the platform 44 and the sparking wheel 41 on one side and the lug 60 on the other side, this lug preventing it from riding off the ratchet wheel 90. The snuffer cap 38 has a bore 86 spaced from a bore l8| by a shoulder 82. In the bore 86 is a cup-shaped member-83 having a bore in its end portion for the reception of the spindle 84 of a catalytic agent holding member generally designated by the numeral 85. On the lower end of the spindle 84 and just above the catalytic agent 88 is fastened a cage member 81. A spring 88 nts in the cup-shaped member 83 one end. of the spring 88 pressing against the insideof the end ofthe cup-shaped member 83 and the other end pressing against the top of the cage member 81. The cup-shaped member 83 is fastened in place in the bore 88 and the upper part of the bore 88 serves as a bearing surface for a head 88 onthe top of the spindle 84. The bore 8| serves as a bearing surface for the cage 81, and thus the member 85 is positioned for limited axial movement in the bores 88 and 8|, being held in one extreme position by the shoulder 82 and cage 81 and in the other extreme position by the head 88 and cup-shaped member 83. The spring 88 urges the member=85 downwardly, but said member is held upwardly when the snuifer 38 is down by engagement of the vertical portions of the cage 81 with the flange 38.

Referring to Figure 3, secured to the abrasive wheel 41 at, one side thereof is a ratchet wheel 88 which preferably has a very small diameter. Mounted on the inside of the snuifer member 83 on a pin 8| extending between the side portions 88 is a multi-toothed pawl member 82 in engagement with the ratchet wheel 98. The teeth of the pawl ,82 are preferably located at the upper end thereof, the lower end being plain, so as to effect rotation of the ratchet wheel only during part of the .upward movement of the snuifer. A spring 83 coiled around the pin 8| urges the pawl member 82 into engagement with the ratch'et Wheel 8 8.

Referring now to Figure 4, upon the pin 8| which receives the spring. 83 is another spring 84 one end of which, like spring 83, is in engagement with the under side of the top portion of the snuifer member, and the other end of which is looped around a latch member 85 which is likewise pivotally mounted on the pin 8| and is urged in the same direction, as regards the snuffer member, as is the multi-toothed pawl member 82. The pawl member 82 and the latch member 85 are located on opposite sides of the plati form 44, the platform 44 together with the top wall flange 45 defining slots for these members..

Referring to Figure 8 the latch member 85 is a generally arcuate shape corresponding to the shape of the multi-toothed pawl member 82, and

on the inner side of the curve are located a pair l f the spring 11 and a releasing` mechanism which will now be described. Referring to Figures -3 and 4, fastened to the outside of the tube 21 is a flat spring 88 (generically this is a flat spring but actually has a somewhat curved shape asv which extend slots |83, |84 are formed in the detent 88A and are engaged by a pair of cam members |85, |88 fastened to the outside of the snuffer cap 38. When the snuifer is down as shown in Figure 3 the cam members |85 and |88 engage the cam slots |83 and |84 and hold the latches |8i, away from the solid fuel 18 which is thus free to rise except that it cannot move upwardly beyond the bottom of the catalytic agent 88 which thus forms a stop for the stick of fuel 18. However much fuel may have burned in the previous use of the lighter, so long as there is any fuel leftit will rise to the level of the bottom of the catalytic agent 88. -Upwa'rd movement of the snuffer 38, however, releases the detent 88 and prevents the fuel 18 from flying out of its retaining tube 21 under the influence of the spring 11.

The operation of the lighter is as follows. Downward movement of the finger piece 58 causes the spring 12 to urge the snufler member 83 upwardly, and the snuffer thereupon rises until the hook portion 88 engages the shaft 48. In rising the snuffer member draws the pawl member 82 over the ratchet wheel `88 and therefore rotates the abrasive wheel 41. During the upward movement of the snuier cap 38 the catalytic agent holding member 85 moves downwardly with respect to the snuifer cap 38 maintaining the catalytic agent 88 in engagement with the upper end of the fuel 18. Sparks from thepyrophoric member 4| impinge upon the catalytic agent 88 and the fuel 18 simultaneously and ignite the fuel 18. It should be noted that the cage 8 1 il so formed that the sparks have easy access to the fuel 18,

and furthermore the back of the snuffer cap 38 is cut away for the same reason, and the cam 'members |85 and |88 are spaced apart to allow l has not been used for a long time it will immediately takeplace after the snuffer cap is elevated once to introduce a new supplyr of oxygen into it. The catalytic agent also increases the vapor tension on the surface of the fuel.

When the finger piece 58 is pushed all the way down the latch operating projection 84 strikes the latch 85 and moves the hook portion 88 out of engagement with the shaft 48. Thereupon the snuilfer cap 38 flies' upwardly to the position shown in Figure 6 and the lighter can now be used to light a cigarette, a cigar, a pipe or anything else. It is noted that the finger piece 58 may be moved downwardly so fast that the two motions of the snuffer will occur one right after the other, and furthermore enough teeth arc placed on the pawl member 82 to throw some sparks after the catalytic agent 88 begins to leave the fuel 18. Furthermore downward movement of the catalytic agent holding member 85 maintains it in engagement with the fuel 18 during part of the second movement of the snuffer.

Extra pieces of pyrophoric material |81 are retained in the tube 38.

Figures 11, l2 and 13 are fragmentary views illustrating a modification of the invention in-' volving direct drive from the finger piece to the sparking wheel. According to this modifica-tion of the invention the sparking wheel continues to rotate during the timethe snuffer is maintained in the position shown in Figure 5. According to this modification of the invention the pawl 92 may be omitted and pawl teeth IIIl provided in one of the side arms 49 of the nger piece 50a. rIhese pawl teeth I IIl engage ratchet teeth serrations I I I Aformed in one side of the sparking wheel 41a. The ratchet teeth serrations I II take the place of the ratchet wheel 90. Preferably a relatively large sparking wheel 41a is employed in connection with this modification of the invention whereby to obtain a large volume of sparks.

Referring now to Figure 14 there is illustrated a. modification of the invention so far as the feeding mechanism for the solid fuel is concerned. The tube 21a, is threaded and in it fits a threaded plug II5 supporting a coil spring IIB which is in engagement with the solid fuel. The plug I I5 has a bore which is substantially square in cross-section and in which fit a pair of wires I I'l desirably formed out of a single piece bent over double, the combined cross-section of the Wires II'I. loosely fitting the bore in the plug H5. The wires Ill are fastened to a cap II8 which is journaled in the bottom wall 22a of the lighter and has a knurled periphery extending beyond said bottom wall so as to be readily rotatable by means of the fingers. Turning of the cap I I8 causes the threaded plug I I5 to travel up or down in the tube 21a.

T'he spring H6 fits over a head II9 provided on the plug II5. This device constitutes manual means for feeding the solid fuel with the spring constituting further feeding means for a limited range. Preferably I provide an escapement mechanism of the type heretofore described in connection with the modification of Figure 14 which, however, may take the simplified form shown in Figure 14.

As shown in Figure 14 the front portion of the tube 21a is cut away to allow a flat spring d20 secured to the outside of the tube 21a to project into engagement with the solid fuel. A spring |25 has a bent-over portion I2I constituting a detent for releasably holding the fuel, and an inclined portion |22 in position to be struck by the edge of the snuffer cap 38a so that the escapement device is in release position when the snufer is closed as shown in Figure 14. When the snuffer d8a is raised the spring causes the portion I2I to engage the solid fuel holding it from rising further under the influence of the spring IIG.

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

As many possible embodiments may be made of the abovefinvention and as many changes might be-made in the embodiment above set forth it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
