POCKET LIGHTER.

Application led April 17, 1924. Serial No. 707,281.

To all wlw-mit may concern: ,I

` Be it known that I, WILHELM BALTRUsoH, a citizen of the German Republic, and residing atlllberfeld, in the Province of RhenishPrussia, Germany, merchant, have invented certain new and useful Imp-rovements in Pocket Lighters, for which I have filed an application for patent in Germany onA April 25, 1923, Serial Nr. 13.109466 X/44b2, vand vof which the following is a l one, the upper or narrow edge of the winspecification.

The invention relates to a pocket lighter `with a chiselor scoop-like scraper mounted on the combustible container and pyrophoric element mounted on the removable closing cap. y

In known rlighters of this kind the pyrophoric element is mounted 4in a separate v holder exchangeably attached to the cap.

Both holde'r and pyrophoric element project to some extent from the wall of the cap, which arrangement is not only unsightly but has the drawback that, qwning to the sharp edges of the holder, the `lining ofthe pocket is damaged or gets torn od. Moreover, in many cases,"owing to the defective fastening method of `the holder the pyrophoric element y easily gets lost.

These drawbacks are obviated by the pocket lighter. according to the present invention in that the pyrophoric element is mounted in a downwardly opening intermediate chamber or longitudinal channel located between the two walls of the double-walled cap, the outer of which walls has a windowlike opening for exposing the operative face of the pyrophoric element. The latter is no longer positioned on the outside ofthe wall of the ca'p, but inside the latter, whereby thelighter has a perfectly closed form and atthe same time damage to the pocketlining is avoided. In addition, the 'pyrophonic element is safeguarded against loss, and finally the separate holder for the element is dispensed with.-

The longitudinal channel for receiving ythe pyrophric element 'fis conveniently formed .of a groove pressed into the inner wall of the cap, so that the outer wall of the latter need be pressed outwardly onlyv little or not at all from its normal level. The pyrophoric element and the groove in the cap-wall containing said element conveniently have the cross-sectionof a -segment'of av circle the flat surface of .the element constitutesthe operative face. In contrad1stnctop of the casing tion to the usual cross-section of pyrophoric,` element, this has the advantagethat the element can 'be used up almost completely whereas in the known rectangular and dove,- tail sections always very large, unusable waste or residue remains behind.

In order to remove the pyrophoric element with little trouble from the chamber between the two walls of the cap when the Worn element is, to be replaced by a fresh can then be pushed downwardly by means` of.a sharp i.mplement,'e.A g. the edgel of a` knife, inserted between the edge of the window and the upper edge of the pyrophoric element. t

An embodiment of the invention is shown by Way ofexample in the, accompanying drawing,` wherein.

Fig. l `is a longitudinal section of the combustible container and the cap (shown removed),

Fig. 2 a side view of the cap, and

Figs. 3, 4 are horizontal sectionsof cap and upper end of said container respectively.

The rectangular combustible containerl which is as usual filled with an absorbent material, e. g. wad, adapted to receive an easily inflammable liquid, for example, benzine, comprises in ,known manner two sheet metal socket-like casings a and b with their open ends engaging the one into the other. The wick-tube c soldered into the a is provided with a scoop or` chisel-like scraper d of steel which is secured in known manner, e. g. by being firmly pressed in. The double-walled cap comprises two sheet metal caps f, g of rectangular cross-section, the closed end of the one being pressed into the closed end of the other. On one of the narrow sides of the cap an inwardly extending curved groove it is pressed into the inner-wall f of the cap, the `wall of which groove engages in a-second groove o in the casing a, of the container .when the cap is put 'on.l Owing to the groove kbeing pressed into the inner wall f of the cap there is formed between said wall and the outer wall g a longitudinal channel, which, according to the invention, serves to sists, for example, of a piece of cerium-iron,

- receive the pyrophoric element i* which conthe latter being pushed into said channel from the lower or open end of the cap. On the same narrow side of the cap, the outer wall of the latter has a window-like opening p, through which the operative face of 4the pyrophoric element is exposed. The latter, and correspondingly with it the channel receiving it, have each the cross section of a segment of a circle, so that the element can be used up almost completely, i. e. without waste. The upper edge q ofthe windowlike opening p cut in the outer cup-wall 1s at a right angle bent inwardly, so that it serves as stop for the p vrophoric element a. In that way the element can be pushed out downwardlywith little trouble by means of an implement inserted between the edge q and upper edge of the element i when 1t is necessary to supply a fresh pyrophorlc element.

The invention is not limited to the embodiment shown, but covers many modifications 'therein or thereof. For exampleA the combustible containelr might be round instead of rectangular and the longitudinal channel instead of being formed by pressing a groove in the inner cap-wallmight be formed by pressing in the outer wall an outwardly projecting groove or longitudinal ridge. "Finally the pyrophoric element, instead of having the segment-like cross-section shown might have the known polygonal cross-section, the longitudinal channel between the two cap-walls being then of polygonal form.
