PYROPHORIC LIGHTER Filed March 16, 1931 INVENTOR fl 81 xfenba ger- B Y vt/ A TTORNEY Patented July 5, 1932 UNITED STATES PATENT .0 Price ADOLF WEISSENBURGER, OF EVILLARD, SWITZERLAND, ASSIGNOR TO THE FIRM, MANN THORENS; S. A., O]? STE. CROIX, SWITZERLAND PYROPI-IORIC LIGHTER Application filed March 16, 1981, Serial No.

This invention relates to pyrophoric lighters and more particularly to portable lighters of this class which are especially suitable for domestic purposes, for instance to light the gas of gas ranges, stoves, furnaces and the like.

It is an object of the invention to provide a pyrophoric lighter of pistol shape in which the fuel reservoir is housed in the handle section of the pistol while the wick is ignited at the end of the relatively long barrel section, in order to have the flame at a certain distance from the fuel reservoir to prevent any danger of explosion.

Another object is the provision of a simple, easily operable ignition mechanism in which actuation of the trigger of the pistol shaped lighter body will automatically ignite the wick.

' A form of construction of a pyrophoric lighter is illustrated in the accompanying drawing in which,

Figure 1 is a viewv of the lighter in position of rest. a

Figure 2 shows the lighter with the wick ignited. b

Figure 3 is a view of the lighter with a side wall removed to show the mechanism in the interior thereof. v

The represented 1i hter has the shape of a pistol with a hand e section 1 and a relatively long barrel section 2. The handle section 1 contains the fuel reservoir m. From the reservoir a wick tube n containing the wick 6 leads to the end of the barrel section. Normally the end of the wick is covered by means of a cover member a rotatably-mounted on the lighter body at c. The provision of the fuel reservoir m in the handle section of the pistol and of the end of the wick at the end of the barrel section has the advantage that the reservoir is relatively far awa fromthe flame when the lighter is ignited, t ereby preventing any danger of explosion which could arise in cases where the fuel reservoir is situated too near the flame so as to become heated by the flame.

The mechanism for igniting the wick b and for moving the cover a comprises a hook e which engages a, segment f provided with 523,098, and in Germany March 17, 1980.

a gear 3 and rotatably mounted at 4. The hook e is pivotably mounted on the trigger d which is adapted to swing about the pivot 5. This book e isjnormally held in enga ement with the recess 17 of the segment f y means of a spring6. To the trig er al is also hinged at 7 an arm 7: provider? with a rack 8. This rack is in mesh with a pinion Z keyed to the pin 0, to which is connected the cover a. g is the friction wheel which is adapted to rotate together with a pinion 9 meshing with the gear 3 of the segment f. A flint stone 10 is applied against the friction wheel 9 by means of a spring 11; the pressure exerted on the flint stone can be adjusted by means of a screw nut 12. v

In order to ignite the wick, the trigger d is pulled back so that the rack 8 of the arm it actuates the pinion Z and the cover a is swung in open position as shown in Figure 2. Simultaneously with the opening of the cover, the hook 6 acts upon the segment 7 and turns this segment in clockwise dlrection about the pivot 4 against the action of the spring 18 which is put under tension. The hook e is provided with a cam surface 5 which is adapt ed to cooperate with a cam surface h of the segment 7. When the'trigger d is near the end of its backward stroke the cam surface It comes into contact with the cam surface 2' and after a predetermined amount of rolling of one of these surfaces along-the other the hook e is depressed against the action of the spring 6 and falls out of enga ement with the recess 17 of the segment ment f then being released, is suddenly pulled back in counterclockwise direction by the spring 13 and the gear 3 meshing with the pinion 9 produces a nick movement of rotation of the friction w eel 9 whereby sparks are thrown from the flint stone 10 to the wick Z) and ignite this latter.

The cover a is held 0 en as long as the trigger is held in its ackward position. When the trigger is released, it is returned in its normal position 'by means of a spring 0. The cover a-is-brought back in its closing position and extinguishes the flame of the wick, while the hook e sliding forwards, will be depressed by the projection 14 of the segment The seg- 7 until it has passed this projection, wherethe toothed segment, a spring acting on said upon the spring 6 will urg it again in ense ent, and cooperating cam surfaces on gagement with the recess 1 After this the said hook and on said segment. 1 lighter is again ready for use.
