12 claims. (o1. vr-'1.1) I

'I'his invention relates tc pocket cigar and cigarette lighters, and particularly, to the type of so-called automatic lighters wherein a light is 'produced automatically on the `application of manual pressure to a controlling member.

My invention contemplates the provision of economical, simple and eiective means for automatically actuating the spark-producing mechanism usually employed in devices of this character and for simultaneously uncapping the wick.

My invention further contemplates the provision of simple and effective means for filling the lighter with liquid or pasty fuel and for thoroughly impregnating the absorbent fuel-holding cotton usually used in such lighters.

My invention further-contemplates the provision of a suitably shaped container and casing of good appearance, adapted for economical production in large quantities, and of means for concealing and covering the operative parts in the closed position of the lighter.

My invention further contemplates the provision of means for putting a maximum pressure upon the pyrophoric material of the lighter so that the production of a spark is assured when the lighter is manipulated.

The various objects of my invention will be clear from the description which follows, and from the drawings, in which,

Fig. 1 is a vertical section of one form of my improved lighter, showing particularly, the means for putting additional pressure on the pyrophoric material when the lighter is operated, and showing, further, one form of the Wheel driving means, and of the means for impregnating the absorbent cotton of the container with fuel by pressure.

Fig. 7 is a front view thereof, showing therposition assumed by certainof the parts in the open position of the lighter.

Fig. 8 is a top plan view thereof in the closed position of the lighter.

In that practical embodiment of my invention which I have illustrated in detail in Figs. 1 to 5 inclusive, I prefer to provide an outer casing as 20 which terminates at its upper end in a suit- `able wind-shield 21 adapted to' substantially enclose the flame produced when the wick 22 is ignited. The wind-shield portion 21 is provided with suitable perforations as 23 to allow .the access of sufficient air to the wick ame to support combustion.

Fitted into the outer casing 20 and adapted to reciprocate vertically or to telescope therein, is the inner casing or container 24. The various operative parts of my improved lighter are preferablysuitably mounted on said inner casing. For'example, the Wick 22 is supported by a suitable bushing 25, secured to the upper end 26 of the container 24, said wick extending into the interior of the container and receiving fuel from the absorbent material 27 which may be cotton or the like, and with which such lighters are usually filled. l For normally capping the wick and preventing the evaporation of fuel therethrough, I provide a Wheel-covering and cap-carrying frame as 28 mounted on the abrading wheel shaft 29. At one end of said frame 28, is secured the wick cap-49 designed to t closely against a shoulder of the wick bushing 25. One or more links as 30 may be provided to connect the side or sides of the frame 28 With the outer casing 20. The link is pivoted at itsrespective ends to the frame and, to the casing by suitable means, such as the screws or rivets 48. On the shaft 29 is loosely mounted the abrading wheel 47 which is providedwith suitable ratchet teeth as 31 on one face thereof. Interposed between the teeth 31 and one side of the frame 28 and operated on the movement of the frame, is the disc ratchet 32 provided with teeth I designed to engage the teeth 31 of the abrading wheel, and to rotate said wheel in the proper direction to strike sparks from the block 33 of pyrophoric material, so that said sparks are directed toward the wick 22. The block 33 is supported in a suitable tube as 34, secured in the interior of the inner casing 24, and preferably though not necessarily projecting slightly above the top thereof.

For exerting pressure upon the block 33 so as to force said block into rm engagement with the abrading wheel, I provide the spring 35 arranged'in the tube 34 and prevented from leaving said tube by the screw 36, which is threaded into the bottom of the outencasing 20. For normally maintaining the parts of my improved lighter in the inoperative positions thereof illustrated in Fig. 1, I prefer to interpose a suitable spring as 37 between the bottom of the inner casing 24 and that of the outer casing 20. Said spring serves the additional function of automatically returning the parts to their normal positions after the lighter has been operated.

Fuel in the form of liquid or paste may be forced into the interior of the inner casing by suitable means provided for that purpose. As illustrated, particularly in Fig. 1, said means takes the form ofa hollow piston or plunger 38 closed at the bottom thereof and fitting quite closely into the tube 39, which is in turn secured in the interior of the imier casing 24, and which is provided with suitable openings as 40 for the discharge of the fuel into the absorbent material 27. As illustrated, the piston or plunger 38 is externally threaded as at 41 to engage suitable threads at the top of the tube 39 and at the top of the inner casing 24, so as to form a tight closure at the top of said tube. Said piston may further be provided with an enlarged head 42 adapted to rest on the top 26 so as to limit the entrance of the piston into the tube. The head 42 is preferably provided with a central perforation communicating withv the inside of the piston, and through which extra blocks of pyrophoric material may be inserted and stored' in the piston for future use. Said lopening is normally closed by thel removable screw 43 which allows access to the interior of the piston when desired.

The operation of that form of my improved lighter which has just been described is as follows:

For inserting fuel into the container, the piston 38 is unscrewed and removed, thereby exposing the upper end of the tube 39. Liquid or paste fuel is then inserted into the tube until it is substantially full. In case of liquid, the fuel will to some extent, be discharged through the openings 40 until the surrounding cotton can absorb no more of the fuel whereupon the remaining fuel will stay in the tube. After the tube 39 has been so filled, the piston 38 is inserted into the top of the tube and forced downwardly, thereby exerting pressure upon the fuel in the tube. Since the piston fits quite closely into said tube, the fuel is forced downwardly and through the openings 40 into the absorbent material 27, thereby thoroughly impregnating said material.

After the piston has been forced down as far as it can go, it may be removed for the operation to be repeated, or if sufficient fuel has been sup- .plied to the lighter, it is screwed into the top of the casing tightly, and forms a suiiiciently tight joint to prevent any material evaporation of the fuel in the container. If any portion of the fuel is left at the bottom of the tube, said fuel gradually penetrates into the absorbent material so that with one filling, the absorbent material, due to its impregnation by pressure, is capable of supplying fuel to the wick over a considerable period of time.

After the container has been lled as above described, the lighter is ready for operation to produce a spark. To do this, the inner casing and the outer casing are telescoped together by manual pressure, against the action of the spring 37. This results in the further insertion of the screw 36 into the tube 34 and the compression of the spring 35, thereby forcing the block 33 of pyrophoric material with greater pressure against the abrading wheel. At the same time, the link 30 rotates the frame 28 and therethrough thev ratchet disc 32 on the shaft 29, to raise said frame into the position shown in Fig. 2. Simultaneously, the teeth on the ratchet disc engage the teeth 31 of the abrading wheel, and rotate said wheel in a clock-wise direction, as viewed in Fig. 1, to strike sparks from the block 33 and to ignite the wick 22 which has meanwhile been uncapped. At the same time, the wind shield 21 is moved beyond the top 26 of the inner casing and protects the iiame from being extinguished by any air currents.

It will be seen that the Wick can be ignited only while the inner and outer casings are maintained in the positions shown in Fig. 2 by manual pressure. When the casings are released, the spring 37 operates to separate said casings and to bring them back into the normal position shown in Fig. 1, the wick being thereby capped by the return of the frame 28 through the agency of the link 30, and the ame capped and extinguished.`

In that embodiment of my improved lighter illustrated in Figs. 6 to 8 inclusive, the outer casing 20 is similar in form to that previously def a bearing in the top 26 of the inner casing, and

a second adjustable bearing as 53 in the bottom of said casing, which is suitably threaded for adjustment.

A slot as 54 is made in said inner casing, through which projects the headed rivet 55, secured to the outer casing at one end, and to the reciprocating nut 56 at its other en d. Said nut is mounted for engagement with the screw threads 52 and is normally urged toits lowermost position by the spring 57, arranged about the shaft 51. A suitable partition as 58 may be provided in the interior of the inner casing 24 to aid in guiding said nut during the reciprocation thereof. For supporting the wick capping frame 28 which carries the wick cap 49, I prefer to provide an extension as 59 on the top 26 of the inner casing, and to pivot said frame to said extension as at 60. The tube 61 for supporting the 'block 33 of pyrophoric material may be closed at one end by a suitable screw 62, which may be used for the purpose also of adjusting the pressure put upon said block through the intermediary of the spring 63 arranged in said tube.

The frame 28 is operated through the link 30, as hereinbefore described. It will be noted that in the normal position of this form of my improved lighter, all of the parts are concealed, and the substantially flat tops and sides only are visible, presenting a good appearance and that the lighter is well adapted to receive suitable ornamentation.

To operate the lighter, the casings 24 and 20 are telescoped together by manual pressure, whereupon any fuel remaining in the tube 39 is forced into the surrounding absorbent material 27 by means of the plunger 38. At the same time, the nut 56 is drawn upwardly by the outer casing, owing to its connection thereto by the rivet 55, against the action of the spring 57, whereby the" shaft 51 is rotated,l as is the wheel 47 and its pivot 60 and vign'ites the'wick which has been uncapped by said frame, while the shield 21 moves beyond the top 26 of the inner casing and protects the resulting ilameon the wick.

After' operation, to produce a light, the respective casings are released, whereupon the spring 57 forces the nut 56 down to its lowermost position and thereby causes the outer casing 20 to move with said nut through the rivet 55 back to the position illustrated in Fig. 6, and resulting in the return of all of the parts back to the normal or closed positions thereof. I
