Lighter with delayed extinguishing of the flame

The present invention relates to pressurized fuel lighters for cigars, cigarettes, tobacco pipes and for use in other cases where a flame is required. An essential feature of the present invention is that the hammer does not go out immediately when the fuel valve is shut off, but that, on the contrary, the flame continues to burn a few seconds after the fuel valve is closed. This enables the user ₉ to fire. generating device ^ to use as a match held between the thumb and the other fingers., the Gebraucher Iceinen "get pressure on Zündrädchen 'upright _s Rauss during .the lighter used wirdo desires beyond the use ,, that the flame a tmbs- '

If the time continues to burn, he can achieve this by using a small amount of hand force to determine certain To slide parts of the lighter into one another and thus close the fuel valve in the open position keep. These features are achieved by providing a metering chamber containing pressurized fuel receives through the valve from the reservoir and by placing a regulator between the metering chamber and the Flame outlet opening is arranged to reduce the pressure. The valve is opened by the relative longitudinal movement between the fuel storage container and the head part b 'actuates the igniter wheel and the flame outlet opening contains. The axial component of the hand force exerted on the ignition wheel causes a relative movement between the parts to open the valve, also causing the pressurized fuel flows to the pressure reducer and flows out of the flame outlet opening. The flame does not come off immediately the lifting of the hand pressure to close the fuel valve is extinguished, the flame continues to burn until the Fuel is consumed in the metering chamber.

When the pressurized fuel storage tank has become empty, the storage tank can be refilled by first removing the head part and then a conventional one filled with fuel

cogs 35 driven in connection. The lower end of the spring 42 stands with an annular spring retaining plate 43 engaging which has a central opening through which the hollow shaft 15 extends. Upright standing, arch-like eyelets 44, which are attached to the plate 43, are in frictional connection with the outer wall 45 of the projection 19 to hold the plate 43 against the force of the spring 42 in position. From this description it can be seen that by turning the ignition wheel 35 against the flint 40 it is effected that Bring sparks into the vicinity of the burner opening 31.

A vent device is provided for introducing fuel under pressure from the chamber 48 within the fuel container 12 into the metering chamber 49 inside the hollow shaft 15. As shown in the drawings, this valve device has openings 50 in the wall of the hollow shaft 15, to be precise surrounded by an "O" ring 51 which is provided in the recess 52 within the fuel storage container 12. A metal retaining ring 55 is disposed in the bore% of the portion 12 for holding the "O" ring 51 with a clamping fit, thereby obtaining a sliding guide for the hollow shaft 15 °. A part 58 of the shaft 15 is enlarged and slides in a bore 59 of the part 12. A spring 60 in the bore 59 comes with a shoulder 61 on the shaft 15 at its upper end and a shoulder 52 on the part

engaged at its lower end. A protruding mandrel at the lower outer end of the shaft 1 5 has a non-circular shape Cross-section and extends through a non-circular opening 64 in part 12. Thus, a Relative rotation between the shaft 15 and the .Part 12 prevented, while a relative axial movement between the two is possible.

With the parts in the position shown in FIG. 2, fuel flowing from chamber 48 and present within bore 59 is prevented under pressure by "O" ring 51 from passing through openings or channels 50 into the metering chamber 49 to flow in. Accordingly, the flow of fuel under pressure from the chamber 48 is shut off. However, when the head 11 is depressed by hand against the action of the spring 60, the hollow shaft 15 moves through the "O" ring 51 down to the position shown in Fig. 5 in which the openings or channels 50 below the ^M 0 "ring 51, which enables the fuel under pressure to flow from the chamber 48 through the non-circular opening into the bore 59, through the openings or channels 50 and into the metering chamber 49 within the hollow shaft 15. The under Pressurized fuel then flows through the line 33 into the head part 11 and through the pressure reducing regulator 25 and through the line 32 to the flame

outlet port 31.

In the working state, the parts are initially in the position shown in FIG. Hand force applied to the top of the detonator wheel 35 causes it to self rotates, generating a downward component which moves the head part 11 and the hollow shaft 15 downward, so that the pressurized fuel into the metering chamber 49 and through the pressure regulator 25 to the flame opening 31 can flow. The by the contact of the toothed Außenuinfangs the ignition wheel 35 with the upper Sparks generated at the end of the flint 40 ignite the fuel escaping through the flame outlet opening 31 Generation of the flames 67 on. A downward movement of the head part 11 in relation to the fuel storage container 12 is prevented by the engagement of the upper end of the rim 21 with the underside of the flange 20.

After the lifting of an upward force on the headboard exerting hand pressure, the spring 60 brings the parts back into the position shown in FIG. 2, the valve parts 50, 51 close in order to prevent further flow of the pressurized fuel into the metering chamber 49. the However, flame 67 is not extinguished immediately, but continues to burn for a short time, for example 3-5 seconds. the Flame continues to burn after the valve has been closed

is because fuel in the metering chamber 49 continues through the Pressure regulator assembly 25 and through the flame outlet port 31 flows until its pressure is exhausted. Thus, the operator does not need to press a hand to maintain the ignition wheel 35 during the period required to light a cigarette, cigar or pipe; the flame continues to burn for a short time, until the fuel in the metering chamber 49 is used up. This is very convenient and expedient for the user is not forced to press his thumb on the ignition wheel to maintain the flame. Instead, you can he the outer surface of the fuel storage container 12 hold between his thumb and other fingers to treat the lighter 10 like a match. This relief is particularly desirable when the tobacco is lit in a tobacco pipe.

If it is now desired that the flame 67 burns continuously, the user can apply downward pressure by hand on the Apply flange 20 of head part 11 to the valve parts in to keep the open position.

When the supply of fuel is under pressure in chamber 48 is used up, it can be refilled in the manner shown in FIG. 6 will. The head part 11 is in relation to the fuel reservoir 12 rotated to sever the thread

16 and 17 between the hollow shaft 15 and the head part 11 to achieve. The shaft 15 does not rotate with respect to the part 12 due to the interlocking non-circular parts 63 and 64. The head part 11 is then axially withdrawn from the part 12 and set aside projecting end 16 of the hollow shaft 15 is brought downward. The downward force moves the shaft 15 downward in order to move the openings or channels into a position below the "O" ring 51 and thus establish a connection between the chamber 48 and the metering chamber 49. The same downward force also acts on the nozzle 71 to the valve 73 to open in the cartridge 70 against the action of the inner spring 74 to the outflow through the conduit 72 to allow. Thus, the downward force exerted by the refill cartridges 70 serves to open the valve 50, 51 within the part 12, as well as to open the conventional valve 73 within the cartridge to allow the pressurized fuel from the cartridge 70 to flow through the metering chamber 49, the Valve 50, 51 and into the chamber 48 within the reservoir 12. After the refilling process has ended, the cartridge 70 is lifted from the shaft 15, the spring 60 closing the valve 50, 51. Then the head part 11 is inserted again.
