Details shown are for exemplary purposes and serve to provide a discussi(I)n of embodiments of the invention. rIThe description and the drawings may be apparent to those skilled in the art !Ihow embodiments of the invention may be practiced.

I I Figure 1 schematically illustrates Ian exemplary gas lighter, according embodiment of the present invention; and I Figure 2 schematically illustrates Ithe exemplary gas lighter, according Ito an I I Io an I I I embodiment of the present invention DETAILED DESCRIPTION I Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the deiltails of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. ii The invention is capable of other embodiments or of being practiced or carried 0|_l1t in various ways. i | According to Jewish law, it is forbidden to light a fire during a Jdwish religious holiday but it is possible to light a fire from another fire source that vslias lit prior to the start of the holiday. For example, it is possible to light a candle befollre the start of the holiday and during the holiday‘ it is possible to pass the flame, for example, to a gas stove. Furthermore, also according to Jewish law, it is forbidden to extinguish a fire during the holiday. V‘ i I An aspect of the present invention relates to a gas lighter which may bl: used to pass a flame from a first fire source to.‘ a second fire source and does not include an ignition mechanism to start the flame. The lighter includes a gas fuel supply lsystem which is used to create the flame, and a.‘ timer mechanism to regulate the duration of the flame. The lighter additionally includes an actuation lever which, when pressed by a user, activates the gas fuel supply system to allow gas flow from the]! lighter which may be ignited to create the flame. Pressing of the actuation lever additlionally activates the timer mechanism. The timer mechanism may include any Isuitable mechanism which may regulate the amount of time that gas flows out of the gas fuel supply system, and may include a mechanical timer, a pneumatic piston and Tizylinder mechanism, a hydraulic mechanism, among others. i I In some embodiments, the gas fuel supply system may include a gas fuel container from which gas may flow through a nozzle in the lighter for igniting the flame. The gas fuel container may be refillable, or alternatively, single iiuse and disposable. The gas lighter may additionally include a gas flow control mechanism which opens and closes a valve in the gas fuel container for lighting and extiriguishing the flame, respectively. The gas flow control mechanism may be mechanically I connected to the actuating lever and may open the gas fuel container valve when then ; .' l l l actuating lever is pressed, and may close the valve when the actuating lever is l returned to, or is proximal to, its initial position. , l In some embodiments, the timer mechanism may include a piston and cylinder arrangement, the piston connected to the actuator lever which when pressed, diives the piston into the cylinder. The cylinder may include a one-way valve through which air may flow out of the cylinder as the piston is driven further into the cylinder. 'l The cylinder may additionally include a spring which may push the piston out of the cylinder in order to return the piston and the actuator lever to their original position prior to pressing of the lever. As a vacuum is substantially formed inside the cylinder when the air flows out of the cylinder through the one-way valve, in order for the piston to be pushed back to its original position, the cylinder may include an intake valve through which air may flow back into the cylinder. Alternatively, the cylinder may be a hydraulic cylinder filled with aifluid, for example, water, instead of air, and may include a fluid tank into which the water flows through the one-way valve? when the piston is pushed into the cylinder and from the which the water flows back into the l cylinder through the intake valve. ' y ' r In some embodiments, the intake valve may be adjustable to allow a user to adjust the amount of time the piston and the actuation lever are returned! to, or proximal to, their initial position, at which time the flame may be automatically extinguished. For example, the adjustable intake valve may be set for a time duration of 3 seconds of pressing after pressing’ of the actuator, 5 seconds after pressing, 10 seconds after pressing, 20 seconds after pressing, 30 seconds after pressing, or more or less. Optionally, the user may preset the time duration to return the actuation lever back to its original position prior to pressing the lever. Additionally, the user may adjust the time duration following pressing of the actuation lever and while the flame is lit. Alternatively, the intake valve may not be adjustable and the time duration is preset by the manufacturer of the gas lighter. V In some embodiments, the lighter may be manufactured in differerit shapes and sizes, and preferably from a relatively lightweight material such as a plastic or a lightweight metal, or any combination thereof, to allow it to be held in a single hand.

Optionally, the lighter may be sized to fit in a shirt pocket or a pants pocket or to be I 6 l l ‘ l 1 I carried inside a handbag. The lighter components may be manufactured from lany suitable material, and may include plastic, metal, rubber, among others. i l In an exemplary mode of operation; when the user wants to light a secondl fire source, for example, a cigarette or a gas stove, from a first fire source, for example a candle, the following steps may be carried out: l ‘ I a. The user presses on the actuator lever. ! b. The user places the end of the noxzle of the lighter against the flame of the 5 » l c. The gas from the lighter ignites and a flame is light at the nozzle‘s end. l first fire source. (1. The user uses the lighter to light the second fire source. e. After the predetermined time, the! timer system shuts of the gas flow in the l l Reference is now made to Figure 1 which schematically illustrates an lighter and the flame is extinguished. exemplary gas lighter 10, according to an embodiment of the present inventionl. The lighter 10 may include a housing 11 with an extender tube 12 through which geis fuel may exit from the lighter to light a flamei 34, a gas fuel container 30 to store galis fuel, a gas fuel conduit 32 extending from the gas fuel container through the nhhusing towards a distal portion of the extender tube and through which gas fuel may flow to light the flame, an actuator lever 14 to activate gas flow through the gas fuel c(!)nduit, and a timer mechanism 15 to control an amount of time gas fuel flows through the gas fuel conduit responsive to a user pressing on the actuator lever. r The lighter 10 may additionally iiiclude a plunger 26 which is connected to the actuator lever 14 at a proximal end and extends into the gas fuel container i30. A distal end of the plunger 26 includes a seal 28 which may seal an outlet port 2% in the gas fuel container 30 to which the gas [fuel conduit 32 is connected. Responsive to pressing of the actuator lever 14, the plunger 26 is displaced inwardly into the gas fuel container 30 removing the seal 28 from the outlet port 29 to allow gas fuel flpw into the gas fuel conduit 32. The plunger 26 may also, responsive to operation of the timer mechanism 15 as described further on‘ below, be displaced outwardly fromlthe gas ? 7 l l l I I fuel container 30 so that the seal 28 covers the outlet port 29 and prevents gas fuel i from flowing into the gas fuel conduit 32. ,i I The timer mechanism 15 may include a piston 36 which is attached toi the actuator lever 14 and a cylinder 18 into which the piston may be displaced inwairdly responsive to pressing of the actuator lever. The cylinder 18 may include a spring mechanism 16 which may push the piston 36, once inside the cylinder, outwardiy to return the actuator lever 14 to its initial (pre-pressed) position. Pushing the pistoir 36, and consequently the actuation level 14,! results in the plunger 26 being retrieved outwardly from the gas fuel container 30 :and the seal 28 covering the outlet port 29 (sealing gas flow to gas fuel conduit 32 and extinguishing flame 34) wheir the actuation lever is returned to its initial position or proximal to the initial position,’ I The timer mechanism 15 may additionally include a regulating mechanism 21 which may allow a user to adjust the rate at which the spring mechanism 16 pushes the actuator lever 14 back to its initial position, for example, corresponding yvith a period of time of 3 seconds, 5 seconds, 7seconds, 10 seconds, 15 seconds, or more, or less. Consequently, the amount of time gas fuel flows through the gas fuel conduit 32 E r The regulating mechanism 21 may include a one-way valve 20 on the cylinder (and the flame 34 is lit) is determined byithe regulating mechanism 21. 16 which may allow air to flow out of the gas fuel cylinder 30 as the pistoir 36 is displaced inwardly into the cylinder. The regulating mechanism 21 may additionally include an adjustable intake valve 22 through which air may flow into the cyliirder 30 and which may include a calibration -screw 24 which may be used to adjust the quantity of air which may flow through the intake valve and thereby adjust the air pressure inside the cylinder. By adjusting the air pressure inside the gas fuel cylinder , the rate at which the spring mechanism 16 pushes the piston 36 outwards from the cylinder may be adjusted, and thereby the amount of time the actuation lever 14 is returned to its initial position.
