Below this bottom wall, the stem section 5d has a member 11 suitably secured thereto, as by a nut 12, said member 11 extending upwardly and terminating in a lateral' section 11a utilizable as hereinafter described.

Secured to and upstanding from the cover plate 2 is a plate-like supporting member 13 on which a pin or axle 14 is horizontally anchored. This pin 14 has a sleeve 15 rotatably mounted thereon, said sleeve 15 having a pinion 16 either formed integrally therewith or anchored thereto so that the sleeve and pinion are rotatable together as a unit. The aforesaid lever 8 comprises an upwardly projecting section 8a which extends through a slot 2a formed in the cover plate 2. As shown on the drawings, this projecting section 8a of the lever 8 is formed with a plurality of rack teeth 8b which mesh with the pinion 16.

A pair of wheels 17 and 18 connected together for movement as a unit are loosely mounted on the aforesaid sleeve 15. As shown, the wheel 17 is a sparking wheel and it is formed with a serrated or roughened peripheral surface, .such surface coacting with a pyrophoric element 19 disposed in the end of an elongated tube 20 suitably anchored in the cover plate 2. A suitablecoil spring, not shown, which is disposed in the tube 20 seats against the upper end of a headed screw 21 and serves to bias the pyrophoric element 19 into engagement with the serrated surface of the wheel 17. The wheel 18 is formed with ratchet teeth on its periphery and coactable therewith is a suitable pawl 22 which, preferably, is of spring steel and so mounted that it tends to swing in a clockwise direction, Fig. 2, about its support 22a, the latter being a projecting section of a disk 23 mounted on that end of the sleeve 15 removed from the pinion 16, said disk 23 being suitably fixed to said sleeve 15 so as to be rotatable therewith as a. unit and a nut 24, if deemed necessary, being threaded to the otherwise free end of the pin 14.

From a consideration of the drawings, it will be observed that the spark-producing mechanism above described is disposed adjacent the cap member 6. Such mechanism is so positioned and arranged that the sparks produced by clockwise rotative movement of the wheel 17, Fig. 2, pass along a diverging path which extends above the cap member 6. Preferably, the spark-producing mechanism is enclosed by a cap structure 25 which is secured to the cover plate 2 in any suitable manner, not shown. This cap structure is provided with a passage 25a through which sparks are adapted to pass along the path above notrd.

Suitably secured to the cover plate 2 and depending therefrom is a plate-like supporting member 26 to the lower flanged surface of which the aforesaid elongated tube 20 may be suitably secured, if desired. Pivoted at 27 to the member 26 and suitably spaced therefrom by a spacing washer is a lever 28 which extends in a generally vertical direction and comprises a notched section 28a coactable with a member 29 projecting from the aforesaid lever 8. The lever 28 further comprises a section 28h which extends in generally a horizontal direction and is so positioned lized a spring 30 which is coiled around the aforesaid spacing sleeve, one end 30a of said spring engaging the lever 28 and the other spring end 30h engaging the member 26.

The above noted fuel casing F, in correspond-l comprises a depending sleeve-like section 32a,`

adapted to be introduced interiorly of the upper end of a vertical passage defined by a structure 33 formed from a strip of suitable laminated materiaLvsuch as felt, which is spirally wound in the manner indicated in Fig. 6 and retained in such configuration by adhesive secured to the adjacent surfaces of the felt strip. Preferably, a member 34 of open mesh material, such as may b e fabricated from copper wire, is disposed around the structure 33 to more firmly retain it in the configuration indicated. Further, as shown in Fig. 2, the lower end of the passage defined by said structure 33 may be closed by a wad 35 of suitable absorbent 'material or the like.

As illustrated in Fig'. 2, the fuel casing F contains a mass of suitable absorbent material 36 such, for example, as cotton. Assuming that this absorbent material 36 together with the structure 33 have been disposed within the fuel casing F as shown, the cap 32`may be secured to the top Wall of said fuel casing F with the sleeve section 32a thereof depending into the upper part of the passage defined by the structure 33. In this manner, saistructure may be held interiorly of the fuel casing F in the position shown in Fig. 2.

The aforesaid cover plate 2` is formed with an opening for the reception of a tubular member 37 which depends from and is anchored to said cover plate 2, the interior passage defined by this tubular member being open at both ends and disposed in alinement with the passage defined by the aforesaid sleeve-like section 32a of the cap member 32.

As shown in Fig. 2, the aforesaid tubular member 37 is adapted to receive, in readily detachable manner, an elongated member 38 formed with a handl'e section 38a, the lower iianged surface of which rests upon the upper end of said tubular member 37. The lower part of the member 38 is shown as received by the continuous passage formed in the cap member 32 and the structure 33.

The member 38 is formed of suitable material such as metal and, as illustrated in Fig. 7, it is of tubular construction and has a stem 39 of metal or equivalent material, this stem carrying a detachable fabric sleeve 40 formed,- for example, from cotton or asbestos strands woven or knitted to form the fabric. The lower end of the stem 39 terminates in a head 41 having a reduced section 41a adapted to be inserted into and frctionally engage the lower interior surface of the member 38. As clearly shown on the drawings, the lower end of the member 38 is cut away to form one or more passages 38h whereby the underlying section the main casing C when it becomes necessary' to` refuel said casing F, the fuel which is thus utilized being of any suitable kind such, for example, as heretofore utilized for supplying conventional pyrophoric lighters. With the present invention, it is desirable that a high test gasoline be utilized for fueling purposes and, accordingly, with the fuel casing F removed from the main casing C, a suitable quantity of such gasoline may be introduced into said fuel casing by passing the same through the opening in the cap 32 thereof. This fuel is taken up largely by the absorbent material 36 and to some extent by the felt structure 33.

With the various parts of the mechanism in normal position as shown in Fig. 2, fuel fumes or liquid fuel as such passes from the absorbent material 36, through the open mesh section 34, and through the felt structure 33, the fuel being then absorbed by the fabric sleeve 40 which. as stated, is disposed within the tubular member 38. Due to the fact that the fabric sleeve 40 extends upwardly within the tubular member 38, it results that the upper part of said fabric sleeve takes up a quantity of fuel and, therefore, in a sense, acts as a fuel reservoir of limited capacity.

With the parts in normal position as shown in Fig. 2. it will be obvious that the lower end of the tubular member 38 serves as a closure for the fuel casing F. This is necessarily true since a close fit exists between said tubular member and the sleeve section 32a of the cap 'member- 32. The vertical passage in the felt structure 33 is somewhat smaller in diameter than that of the tubular member 38 and, therefore, the latter is resiliently engaged and gripped by said felt structure 33 to thereby enhance the sealing action to somev extent.

when the herein described mechanism is to be operated, the handle section 38a is grasped by the fingers of one hand and lifted upwardly to entirely remove the member 38 from the tubular member 37. The member 38 is then disposed in the position shown in Fig. 1 with the head 41 at the lower end thereof disposed within the recess 6a of the cap member 6. While thus held in substantially vertical position, downwardy pressure is applied to the member 38 and, as a result, the

member 5 is moved downwardly within the hol-l low cylinder 3 to thereby compress the springs 7 and 10. During this initial downward movement of the member 5, the lever 8 remains stationary by reason of the fact that the lateral pin 29 thereof is in engagement with the notched section 28a of the lever 28.

As hereinbefore stated, thestem section 5d of the member 5 and the member 11 are. connected to the member 5 for movement together as a unit. Accordingly, during downward movement of the 'member 5, the lateral section 11a of the memsurface for the bottom section of the spring 7,

is freed from restraint and, accordingly,fsaid spring 7 expands suddenly to thereby rock said lever 8 in a clockwise direction, Figs. 2 and 7,

The pawl 22 is carrection, Figs. 2 and 7. The serrated wheel 17 I moves with the ratchet wheel 18 as a unit and, therefore, said serrated wheel 17 partakes of a quick step of rotative movement and, because engaged by the pyrophoric element 19, serves to produce a shower of sparks which are directed along a path extending toward and above the cap member 6. Inasmuch as the member 38 is pressed downwardly against the cap member 6 at this time, it results that the pyrophoric sparks ignite the fuel carried by the exposed sections of the ,fabric sleeve 40.

As a result of the foregoing, a flame is produced at the lower end of lthe member 38 which becomes, in effect, a torch and, as such, it may be used to perform any desired lighting operation. The torch may readily and quickly be conveyed to any object to be ignited and, in so doing, it may be passed from hand to hand or to different persons in order to' accomplish a plurality of lighting operations.

After the member 38 has servedv its intended purpose as a torch, it may be reinserted into and -passed downwardly through the 'tubular member member 38 has been returned to its normal position as shown in Fig. 2, fuel is taken up by the wick member 40 at the exposed wick sections defined by the openings 38h. 'Ihis fuel, to some extent, is absorbed by the upper section of the wick member 40 removed from the openings 38h. 'I'he member 38, therefore, is welladapted for subsequent use as a torch because it contains a quantity of fuel suiilcient to maintain a freely burning flame for an extended period of time.

When the member 5 was moved downwardly by the member 38 -as described, the springs 7 and 10 were compressed. When the notched lever section 28a became disengaged from the pin 29,

lsudden expansion of the spring 7 occurred and this was accompanied by further compression of the spring 10, the spring 7, at this time, becoming fully expanded or substantially so.

As soonas the torch member 38 is removed fromthe member 5. the spring 10 is permitted to expand to return the parts to their normal respective positions as shown in Fig. 2. In so doing, the member 5 is moved upwardly to elevate the spring 7 and to swing the lever 8 in a counterclockwise direction, Fig. 2, to such extent that the pin 29 thereon is again engaged with the notched end 28a of the lever 28 which is biased in a clockwise direction, Fig. 2, by the spring 30. When the lever 8 is thus swung in a counterclockwise direction, the pinion 16, sleeve 15 and disk 23 partake of a step of reverse rotative movement. During such movement, the pawl 22 idles with respect to the ratchet wheel'18 and, therefore, this wheel together with the serrated wheel 17 remain stationary.

As clearly appears from a consideration of Fig. 2, the spring 7 should be heavy" while the spring 10 should be light, 'That is, the spring '7, to a suitable degree, should be more resistant to compression than the spring 10.

The spring '1, or equivalent, of the herein described mechanism serves as a means for actuating the spark-producing means by a snap action to produce the desired shower of sparks. While storing energy in the spring 7 and, thereafter, operation of said spring for the intended purpose is restrained by the latching means comprising the lever 28,v or equivalent. In the preferred form of the invention herein shown, energy is stored in the spring 7, or equivalent, and the latching means is released by operating means which comprises the member 38, or equivalent, carrying the charge of fuel.

It is to be understood that the mechanism hereinbefore specifically described is illustrative of but one of the many embodiments of the invention. Thus, for example, in lieu of the described spark-producing mechanism, -it shall be understood that other equivalent arrangements for obtaining uni-directional movement of a serrated wheel may be utilized. Furthermore, it is to beunderstood that fuel may be Supplied to the fuel casing F in any convenient manner otherwise than as herein described. It shall also be understood that the sealing arrangement for the lower end of the tubular member 50 may assume any one of a. variety of forms in accordance with the broad purview of the invention.

While the invention has been described wit respect to a certain particular preferred example which gives satisfactory results, it will be understood by those skilled in the art after understanding the invention, that Various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modica'- tions.
