MATHIAS FANKL Attorney l l l l Patented Dec. 6, 1949 POCKET LIGHTER Mathias Fankl, Vienna, Austria, assignor to Karl Bernhardt, London, England Application July 30, 1347, Serial No. 764,763 In Germany December 27, 1938 Section 1, Public Law 690, August 8, 1946 Patent expires December 27, 1958 5 Claims.

Pocket lighters are known having several liquid fuel containers independent of each other, in particular double tank lighters, having a oint ignition device ,for the individual ignition means (wicks) adapted to be inserted in two different positions into recesses of the fuel container by the aid of a projection which holds the means for guiding and pressing the igniting or cerium stone.

The present invention has for its object to facilitate the manipulation in exchanging the cerium stone of double tank lighters of the aforesaid kind without complicating its design, this object being attained by combining several particular measures and by providing special constructive arrangements. A pocket lighter according to the invention is characterized in that the ignition device is provided with an extension formed-in the longitudinal section-as a T- shaped body, whereby said extension protrudes into the upper part of the fuel container, and that the presser for the cerium stone consists of a plate spring of which the one end rests against the cerium stone, and further that the free end of the spring is fitted with a handle with which the other spring end may be pressed against an abutment on the extension, or may be lifted from said abutment for the purpose of exchanging the cerium stone, said handle entering between the. two arms of the spring with the extension inserted into a frame or opening of the lighter casing.

' The drawing shows an embodiment of the invention by way of example Fig. 1 being a front elevation of the lighter according to the invention, whereas Figs. 2 and 3 are a view from below of the ignition device and a vertical section through same, both being represented on an enlarged scale.

Numeral designates the pocket lighter casing comprising the two fuel containers 2 and 3 where as 4 and 5 are the filling screws coordinated to the fuel containers 2 and 3. Each of the independent fuel containers 2 and 3 has a wick frame 6 and of its own in which the wicks 8, 9 are arranged. The igniting means (wicks 8, 9), coordinated to the individual fuel containers 2 and 3, are inflammable according to desire by the ignition device H1 having a projection I alternatively insertable in two different positions displaced by 180 in respect to each other in a frame or opening l3 formed by the recesses H, |'2 of the fuel container.

The ignition device is designed in the usual intended for the wick actually not in use.

manner consisting of a tiltable lid I4 pivotable about the axle which serves simultaneously for rotatably supporting the friction wheel I! provided with claws Hi. The extension 22 of the lid I4 is engaged by the spring l8 whose other end is fastened to the presser I9. Said presser I9 is tiltable about the pin coacting at its other end 2| with the projection 22 of the lid M as will be explained in detail below.

In the projection I0 used for changing over the ignition device [0 the guiding and pressing means 23 and 24 for the cerium stone 25 are provided. The pressing means for the cerium stone 25 consist of a wire spring 24, the one end of which bears against the cerium stone whereas the other end can be applied against an abutment 28 if it is desired to release the cerium stone 25. The ignition device l0 carries two wick caps 29 and 30 provided for the two wicks 8 and 9 of the two fuel containers 2 and 3 whereas the cap 29 is connected to the lid l4 elastically supported by the spring |'8, which has the effect of elastically and yieldingly supporting, in the ignition device casing, the second wick cap 30 elasticity and yieldability of the cap 30 necessary for a tight closure of the wick, not used, can be brought about by the arrangement of a plate spring 3| whereby the oblong hole 32 provided in the easing, into which a guide pin 33 of the cap 30 is made to engage, warrants an appropriate mobility of the cap.

The pocket lighter according to the present invention is operated as follows: In the position of the individual parts represented in Fig. 1 the ignition device I!) is applied for infiaming the wick 8 of the fuel container 2 on the right hand side. The inflammation is effected, in a manner known, by depressing the presser l9 whereby the extension 22 of the lid I4 is pushed downwards overcoming the effect of the spring l8 whereby said spring |B. is moved into its dead center and finally shoots out jerkily in the other direction (position indicated by a dash-dot-line in Fig. 3) in consequence} whereof the friction wheel I! driven by the lid in a manner known acts on the cerium stone 25 so as to form sparks. During the process the second cap 30 acted upon by the plate spring 3| tightly closes the second wick 9 (Fig. 1).

If the fuel container 2 does not hold any fuel anymore or if the inflammation miscarries, the ignition device is simply withdrawn from the frame or opening I3, is turned by and is then reinserted into the frame in its new posi- The,

tion so that the ignition device will then occupy the position required for inflaming the second wick 9. The outer contours of the pocket lighter are not altered by this change-over of the ignition ,device. Oontemplated in the same direction the contours of the lighter in :the new position are equal to those of the old position as reflected by a mirror.

The exchange of the cerium stone 25 is carried V out by means of the handle 21 which permits a '4. In a pocket lighter as claimed in claim 3, an elongated tube in said projection carrying said of lifting from the abutment '28 the part of :the

What'l claim is:

l. A pocket lighter comprising an outer casing, two separate fuelcontainers arrangedin said casing in side-by-side relationship and each having a w'ick inserted therein, each said con tainerhav ing a recess in :an'upper corner thereof, said recesses being in :abutting relationship and forming -a rectangular shaped pocket, an ignition head forsa'id-lig'liter, said ignition head comprising a casing having equal dimensions with an end of said "outer casing, a rectangular projection on said head casing -extending'therebelow into said rectangular pocket, sparking means in said ignitionhead including -'a friction wheel and a-fiint=for igniting awick, said ignition head being removable and reversible for igniting one or the other of said wicks separabiy.

"2. In a pocket lig'l iter 'as claimed in claim 1', said ignition headcasing'be'ing hollow and having a pin therethrough, 'a tiltable lid pivotally securedonsa'id pin and iorming an end of said lid, a pressure responsive member tiltably secured to said casing at theend remote from said lid and iorming'a second portion of said casing, a spring secured to said member and to said projection on said'lid, said spring be'ingbiassed to hold said member and said lid in inoperative position, said friction-Wheel comprising a-portion-of said sparking :means being secured on said pin and being rotatable therewith, said pressure responsive inem-ber being actuable against the action of said biassed spring to pivot said lid around said pin for exposing a wick and to turn said friction wheel against said flint.
