This invention relates to acigar lighter,

and relates more particularl to'a pocket cigar lighter of the type in w icha-friction .wheel is rotated in contact with a body of a pyrophoric alloy for producing a spark emission which serves to ignite a" fuel containing wick. I

- In pocket cigar lighters of this class a liquid fuel is contained in a receptacle, the

top or cover of which carries the operating parts of thelighter which include a wick 'tube, a holder for a body of pyrophoric al-- loy, the actuating means cooperating with the alloy for producing the spark emission, 1 and a snufler device cooperating with the wick. Amon cigar lighter 0 this type are the rovision of, a receptacle construction whic is proof against leakage or evaporation of the liquid fuel contents thereof, the provision of aconstruction and assemblage of "the operating parts which possesses ruggedness and relia bility of action, and theprovision of suchan organization of all of the parts which affords e'ase of manufacturing, assembling and finishing operations- A prime'object of my invention centers about the provision of'a pocket cigar lighter in which these combined desiderata are effectively accomplished.

To the accom lishmentofthe' foregoing and such other '0 jects as will hereinafter ap-' pear, my invention consists in the elements and their relation one to the other as herearticularly described and inafter more sought to be de ed in the claims, reference bein had to the accompanying drawings whic show the preferred embodiment of my invention, and in which- 1 Fig. 1 is a vertical elevationalview of the cigar lighter of my present invention, the

same being shown in section taken in the the downwardly extending or depending plane of the line 1-1, Fig. 4,

Fig. 2 'is a top plan view thereof with a part broken away, 7 Fig. 3 is a fragmentary view of the same taken in cross-section in the plane of the line accomplish ineffective combination the dethe' prime desiderata in a- -of parts which a operations, the resulting construction pos- *ing parts mounted thereon is so constructed and related to the-receptacle casing as to 05 sired objects of'p'roducinga leak and evaporationproof receptacle and an organization ords ease and convenience of manufacturing, assembling and finishing sessing the desired ruggedness and reliability of: action. This I accomplish by making the cover wall 12 in the form of a metal cast ing embodying supporting and housing means'for lighter operating elements, specifically, awi'cktube 17, a spring plunger hous- ,.ing '19 anda cooperating support 20 for the snufl'er arm,'18,"as well as a standard or post 21 for the pyrophoric body container 14, all cast into an'integral unit, and by then relating this unitary casting with the casing wall 11 in such a way as toproduce a leak-proof joint therebetween.

i More specifically, therefore, the cover-wall 12 is made in the form of; a metal casting having asubstantially thick plate section 22 terminating in a marginal lip 23 and provided with a depending marginal flange portion 24 set sli htlyinwardly of the lip 23, the said plate being cast-as an integral unit with the upwardly extending wickj tube 17 as i none of the supporting parts for the operating elements are joined to'the cover plate by any means, as is the case in prior constructions, whlch are subject to being loosened and thus producing undesirable leak crevices afford, a wider latitudeand greater convenience in producing'a finished appearance for the receptacle casing, which usually-is made of a costly metal, the cover-plate 12 is combined with the casing wall 11 without'the use of sealing...mea'ns such as solder heretofore employed at the joining edges. This result is preferably accomplished by the making of the upper wall 12 in the form of a casting which provides the marginal flange 24, the

' latter serving as a substantially rigid forming means over which the comparatively yieldable metal casing wall 11 is fitted. By reference to Figs. 1 and 3 of the drawings, it will be noted that the top of the casing wall 11 is fitted over the marginal flange 24; this being done with a binding fit, the organization and use of materials being such that the ceive the rivets.

upper part of-the casing wall 11 takes the form and shape of the marginal flange and makes therewith a leak-proof joint, this being assisted by the engagement of the upper margin of the wall 11 with the cover lip 23. By

means of this interrelation of the parts I have foundthat it is entirely unnecessary to solder the joint between these parts, and that it is suflicient in order to permanently prevent detachment of the parts to secure the same together by additional interengagi'ng and locking means, inthis case a pair of rivets 27 and 28, the depending flange portion 24 being preferably bossed at the points which re- Toprovide for a leak-proof joint for the bottom of the casing wall 11, the cover wall 13 is also constructed in the form of a casting embodying a plate 29 similar to the-top cover plate having a marginal lip 30 and an inwardly set flange 31,, which flange receives the bottom portion of the casing wall 11 with a binding fit, the parts being secured:

together by means of the oppositely positioned rivets 32 and 33, this construction also providing a leak-proof joint.

-To carry out the desideratum of eliminating special tooling operations and s ecial securing elements, the pyrophoric bo of an externally toothed section 34 provided tion is forced into the wall of the-aperture 26 y holder 14 is attached to the post 21 bythe provisionusual adjusting screw 35 acting on a spring I and plunger 36 which in turn is active against the pyrophoric body 15.

Cooperating with the pyrophoric body I provide the operating means heretofore des-, ignated as 16 which comprises a friction wheel 37 force-fitted onto a sleeve 38 formed integrally with an operating finger wheel 39, the same being force-fitted onto a spindle 40 which is loosely journalled in the extending part 41 of the tube 14 and in the aperture 42 provided in the cover plate 12. The snuffer device 18 preferably comprises an arm 43 having at one end a block44 journaled in the pivot pin 45, said block having two of its faces cooperating with a spring-pressed plunger 45 housed by the casing 19 operative for holding the snuffer device in either itsclosed or open position, the saids nuffer device 18 at its other end including a snufler box 46 and a cover 47 integral therewith, said cover fitting over the sparking wheel 37.

The snuifer box 46 is provided internally with a tube 48 which fits over the wick tube 17 said wick tube being internally provided with the tubular element 49 which snugly holds the wick 50.

The bottom plate 29 may'be provided with the customary holder 51 for refills, said holder being threadedly removable from a cap 52 which in turn defines a filling closure threadedly removable from the bottom plate 29.

The use and operation of the cigar lighter of my present invention and the many advantages thereof will in the main, be fully ap parent from the above detailed description thereof. It will be particularly seen that the manner of'constru cting and organizing the parts is such as to permit the manufacturing of a minimum number of parts and the assembling thereof with a minimum of securing elements,all to the end of producing a very rigid structure having a certainty of action. It will be also apparent that the parts are so designed as to minimize any such leak crevices as appear after some use in prior devices, through Which crevices the volatile liquid fuel readily evaporates. It will be further seen that the cover and bottom plates are so joined to the casing wall as to permit the obtaining of leak-proof joints without the use'of solder heretofore employed, this permitting a greater convenience and range of use of diflerent finishes for the metals employed in devices of this character.

' It will be further-apparent that while I have shown and described 'my invention in centrallyof the'tube 14, which toothed secthe preferred form, many changes and modiclosed without departing from the spirit of the invention, defined in the following claims.
