6 Claims.

This invention relates to a lighter, and has for one of its objects to provide a more simple constructionfor ignition of the wick of a lighter which will be operated by manual pressure upon a nger piece or the like and mechanically returned to initial position upon release of pressure on the finger piece. p

Another object of this invention is the provision of a finger piece which is freely pivotally mounted and moved in one direction by movement of the snufer as distinguished from the direct action of the spring on the finger piece itself, there being no connection between the snuffer and finger piece, but each being independently mounted except for the abutting relation of the said parts which occurs for movement in one direction only.

Another object of this invention isthe provision of a spring mounted about the pivotal axis of the snuffer which will engage a portion of the topwall of the casing and the snuier to directly act upon the snuer and move the same to'closed position thereby simplifying the construction and assembly of the parts.

A further object of this invention is the supporting of the pyrophoric tube at its end where it projects into the recess in the top Wall to strengthen the construction, the same being accomplished by a simple projecting part from the top wall.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In lighter construction it is often considered desirable to provide a mechanical arrangement such that pressure upon the finger piece will 60 cause rotation of a friction Wheel to throw sparks from the pyrophoric material on to the wick to ignite the same, the action taking. place upon the lifting of the snuffer from the wick covering position, and in order that a construction of this character may be simplified and yet one which will work with ease, I have provided a snuffer which is so mounted that a spring will act on the snuier itself to move the same to closed position and which may be lifted from this closed position either by directly engaging the snufer or by means of a finger piece which is mounted to engage Athe snulier to lift the same, although the finger piece is entirely independently mounted Vof the snulfer itself; and the following `is a detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplished.

With reference to the drawing, Ill designates the fuel casing having the packing of absorbent material H contained therein and provided with a bottom wall i2 having a filling opening I3 closed by a screw-threaded plug l and having a pyrophoric tube I5 extending upwardly through the casing closed bythe screw-threaded plug it. i

The casing It is provided with a top wall l? shown in perspective in Fig. 3 as being cut out at I8 inwardly from the periphery thereof in the shape best shown in Fig. 3, with an opening it also provided in this top wall and a iinger 2G extending into this opening I8 and bent downwardly as illustrated in Fig. 3. Openings 2i and 22 are provided in the nger for the purposes more fully and hereinafter explained.

A dish shaped member 23 as shown in Fig. 4 is secured to the lower surface of the top wall ll by means of solder or the like to suspend the same therefrom and from this Wall there projects upwardly support langes 2li extending through notches 25 in the top wall and provided with openings 26 and 21 to provide bearings for the pivot shafts for the operating parts of the device.

The pyrophoric tube l5 is bent in somewhat of an offset path to permit the better packing of the absorbent material ll in the casing, and this tube projects through the dished member 23 into the recess formed in the top wall and through the opening 2l in the nger 20 to be supported thereby.

The spring 28 in the pyrophoric tube forces the pyrophoric material 29 upwardly into engagement with the friction wheel 30 which is pivotally mounted upon a shaft 3l having bearings in the openings 21 in the support iianges 24.

A shaft 32 is mounted in the openings 26 in this support iiange 24 and upon this shaft there is pivotally mounted the snuier member 33 which has the tubular cap portion 34 to close over the wick 35 projecting upwarcy through the casing I0 and supported by a boss 36. This snuer member is moved to closed position by means of a coiled spring 31 embracing the pivotal shaft 32 and having one end 38 engaging th'e under surface of the snuffer and the other end 319 anchored in the opening 22 in the finger 20 which projects from the top wall and which spring tends to move this snuffer about its pivotal point to cover the wick.

In order that the friction wheel may be operated upon raising the snuffer, I have provided a rack pivoted at 4l on the underside of the snuii'erl member with a. spring' 42 to swing this rack toward the axis of the friction wheel into engagement with a ratchet wheel 43 which is keyed to the friction wheel to move therewith, the operation belng'such that upon raising the snuffer the wheel isl rotated to ignite the wick but upon release this snuifer returns to position with the rack swinging outwardly to slip over the teeth of the ratchet wheel, which is held in position by its frictional engagement with the pyrophoric material 29, the shape of the teeth of the ratchet wheel and the teeth on the rack being such to cause engagement of the same in one direction and release by movement in the other direction.

A construction as thus far described is complete within itself and is illustrated in Fig. '7 with the parts correspondingly numbered, although somewhat different in shape and detailed arrangement. It may be desired, however, that a finger operating member be provided to swing this snuifer to open position rather than by picking up the snuffer from its front end 44 or direct manual pressure upon the 4rear end 45, as shown in Fig. 7, and in order to accomplish this result I have provided in Figs. 1, 2, and 6 a piv- 40 oted finger piece indicated generally 46 which is pivotally mounted on the axis of the friction wheel by means of a bearing opening 41 in the ange thereof, there being a slot 48 to permit movement of this finger piece about the fixed shaft 32 upon which the snufer is mounted.

This finger piece is provided with a top portion 49 which extends over the end of the snufier so that upon pressure of the finger piece downwardly it will swing about the pivot 41 and force one end of the snuifer downwardly and the operating end upwardly into the position illustrated in Fig. 2, there being a sliding of the under surface of the finger piece along the top surface of the snuffer in this action.

The finger piece is kentirely independent of the snuifer and may be lifted from its position in Fig. 2, while the snuifer is open, but in use the linger piece will return to its initial starting position upon release of pressure upon it by reason of the snuffer returning to its closed position under action of the spring 31 and carrying with the snuier the finger piece by reason of engagement therewith.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
