DISPOSABLE FIREPLACE AND OVEN LIGHTER BACKGROUND OF THE INVENTION The invention is directed to an improvement in gas lighters of the type disclosed in US. Pat. Nos. 3,533,718 and 3,157,038. These lighters which are generally referred to as butane lighters" have gained wide acceptance as a conventional lighter for lighting cigarettes, cigars and the like. Such lighters generally comprise a housing having a reservoir for holding a supply of volatile liquid fuel. A movable valve is operatively associated with the fuel reservoir to control the flow of the gaseous or volatilized fuel from the reservoir to maintain ignition. An igniting means generally in the form of a friction sparking wheel is provided to ignite the escaping gas when the valve is opened. Lighters of this type are provided with a valve opening mechanism arranged for actuation simultaneously with the actuation of the sparking wheel.

In such known lighters it has been necessary for the user to maintain a physical pressure or force on the valve actuator to keep the same in an open position so as to maintain the resultant flame. For this reason. it is impossible for the user to maintain such pressure on the valve actuator for any extended time interval; and at the same time remove one's hand to a safe holding position which is necessary, when one is lighting an oven, fireplace, barbecue or the like. This is particularly the case when such lighters are designed to be held in the palm of the hand so that the requisite pressure had to be maintained by the thumb of the holding hand.

Also, such lighters have been proved practical only when the lighter is held in a vertical position, Any effort to utilize the ligher when burning in a non-vertical position would cause the flame to flare back uncomfortably close to the users thumb which is maintaining the pressure on the valve actuator. This diadvantage is particularly troublesome in the case of the inexpensive lighters which have no flame adjustment feature. Even on the more expensive lighters having a flame adjustment means, which controls the rate of flow of gas fuel to thereby avoid flareback of the flame toward ones hand; the noted disadvantage will materialize when the pressure of the gas is diminished with use.

OBJECTS OF THE INVENTION An object of this invention is to provide a disposable gas lighter in which the flame can be maintained at a safe distance from the users hand; independently of any applied force on the part of the operator.

Another object of this invention is to provide a gas lighter in which the fuel valve can be mechanically locked in its on position upon ignition.

Another object is to provide a gas lighter in which the fuel valve is automatically mechanically locked in open position simultaneously with the actuation of the sparking ignition wheel.

Another object is to provide a gas lighter with an extension housing whereby it can be safely used in any position.

Another object is to provide a gas lighter with extended body which have complementary means to mechanically lock the fuel valve in open position.

BRIEF DESCRIPTION The foregoing objects and other advantages are attained by a gas lighter which comprises a housing hav ing a reservoir for containing a volatile liquid fuel and a normally closed valve for controlling the flow of gaseous fuel. Operatively associated with the valve is an actuator which is positioned relative to the sparking or ignition wheel so that the actuator can be actuated simultaneously upon a user actuating the ignition or sparking wheel. In accordance to this invention, a mechanical latching means is provided to mechanically latch the valve actuator in the valve open position so that ignition of the lighter can be maintained over an extended period of time independent of any applied force being maintained on the valve actuator by the user. This is attained by providing a valve actuator with an extended latching portion adapted to engage a complementary catch formed on an adjacent housing part. The invention further contemplates an housing or body extension adapted to receive the housing of the lighter whereby the lighter may be utilized as a torch. The housing body extension may be provided with a com plementary catch to cooperate with and engage the valves actuator latch to mechanically maintain ignition of the lighter.

FEATURES A feature of this invention resides in the provision of a relatively inexpensive and positive acting mechanical locking mechanism for locking the valve of a gas lighter in open position to maiantain ignition independent of any holding force applied by the user.

Another feature of this invention resides in a positive mechanical valve locking mechanism which can be readily applied to existing lighter construction with a minimum of any structural changes. I

Another feature resides in the provision ofa body extension for adapting the lighter for use as a lighting torch for purposes other than lighting cigarettes or cigars.

Another feature resides in the provision of a body ex tension for a gas lighter having a catch means for cooperating with a valve actuator catch for mechanically locking the gas valve of a gas burner in open position.

Other features and advantages will become more readily apparent when considered in view of the drawings and specification in which:

FIG. 1 is a side elevation view of a gas lighter embodying the invention having parts shown in section.

FIG. 2 is a fragmentary enlarged sectional view of the lighter of FIG. 1.

FIG. 3 is a side view of a modified embodiment.

DETAILED DESCRIPTION Referring to the drawings. there is shown in FIGS. 1 and 2 a lighter construction 10 embodying the present invention. The lighter 10 is a gas lighter which utilizes a highly volatile liquid fuel, e.g., butane, and may be generally referred to as a butane gas lighter. Such lighters have gained wide acceptance as cigarette and cigar lighters. The lighter 10 comprises a housing 11 having a reservoir 12 adapted to contain a supply of volatile liquid fuel, e.g., butane. The upper end of the reservoir is provided with an outlet opening 13 which is connected to the inlet of a gas valve 14. The gas valve 14 is of conventional construction having a nozzle end 14A which is normally maintained in a closed position.

Thus the valve 14 comprises a normally closed valve. The reservoir 12 of the lighter may be filled through an injector filler valve 15 located in the bottom end of the housing.

Mounted on the upper end of the housing 12 in igniting relationship with the gas valve or nozzle 14A is a sparking or ignition wheel 16. The periphery of the wheel 16 is provided with a roughened surface arranged to engage a flint or spark generating means which is normally urged against the periphery of the wheel. The sparking wheel is rotatably journalled on a post 17 extending beyond the top of the housing.

Pivotally mounted on the post 17 adjacent the sparking wheel 16 is a valve actuator 18. The valve actuator comprises a lever having one end 18A bifurcated to engage a reduced portion of the valve nozzle 14A. Thus the end 18A of the actuator 18 is suitably connected to the valve nozzle to effect the opening of the valve when actuated. as will be hereinafter described.

The outer end 18A of the valve actuator is extended beyond the periphery of the housing and is formed with a spring detent or latch 19. Adjacent the latch end 19, the housing is provided with a projecting catch 20 which is in the form of a protuberance which constitutes preferably a part of the housing 11.

As seen in FIG. 1 and by the solid line showing in FIG. 2, in the normal inoperative position, the latch end 18A of the actuator 18 is spaced above the catch 20. In this position the valve 14 is normally closed.

It will be noted that the valve actuator 18 is disposed relative to the sparking wheel and the valve nozzle 14A so that in operation, the latch end 18A of the actuator is normally or automatically depressed when the sparking wheel is rotated to effect ignition of the lighter 10. The natural movement is such that the extended end 18A of the actuator is depressed whereupon the latch or spring detent 19 automatically engages or hooks the catch 20 to lock the valve in open position. In this manner the valve can be maintained in an open ignited position for as long as desired without the user maintaining a physical force on the valve actuator 14.

To release the catch 19 to close the valve, the operator need only to apply slight upward pressure on the latch 19 to disengage it from the catch 20. The spring (not shown) which acts on the valve 14 to normally maintain the valve 14in closed position insures positive release of the latch 19 when disengaged from the catch 20.

With the construction described, it will be apparent that an operator while holding the lighter 10 in the palm of his hand in the usual manner can effect simultaneous lighting and locking of the valve 14 in the open position by the same thumb motion required for lighting conventional lighters; and that the flame can be extinguished by a reverse flick of the thumb of the holding hand. It will also be apparent that the described invention can be incorporated in a lighter without substantially altering the lighters of known construction.

To provide additional versatility to the lighter construction 10 described, there is provided a tubular housing extension 21 which is opened at one end 21A which is sized to frictionally receive and retain the lighter 10 herein described. The housing extension thus provides the lighter 10 with the additional versatility in that the lighter may be used as a torch or ignitor to ignite fire places, ovens, barbecues and the like. Thus when the lighter 10 is used to start fire place fires, and

the like. as shown in FIG. 3, the housing extension enables one to hold the lighter so that the tendency of the flame comeback cannot burn or injure the holder. It will be further apparent that the locking means 19 and 20 described enables the lighter adaptable for use with the housing extension, since the locking means 19, 2O enables the ignition ofthe lighter 10 to be maintained without the need for the operator to physically maintain the valve 14 open. If desired a hanging loop 10 or hook 22 may be connected to the other end 218 of the housing extension 21.

FIG. 4 illustrates a modified housing extension 31. This extension may be similar to that described with respect to FIG. 3, except that extension 31 is provided with a catch 32 which is adapted to engage the locking latch 18 of a lighter.

However it will be understood that a lighter utilized in conjunction with the housing extension 31 does not require the catch projection as shown in FIGS. 1 and 2. Thus in the combination of FIG. 4, the latch 38 of lighter 10A is cooperative with the catch 32 which is formed on the housing extension 31.

In all other respects the operation and construction the lighter combination of FIG. 4 is similar to that hereinbefore described.

While the invention has been described with respect to various embodiments thereof, it will be understood and appreciated that variations and modifications may be made without departing from the spirit or scope of the invention.
