8 Claims. (Cl. 67-7) The present invention relates to flameless lighters, and in particular to cigarette lighters of the catalytic type equipped with an element which becomes incandescent to afford lighting of the cigarette or like smoking article.

It is one of the primary objects of the present invention to provide means facilitating highly efficient operation of a flameless lighter of the aforesaid type without the necessity of directing to said element suction or puffing action by a persons mouth to bring about incandescence of the lighter element while the cigarette or like tobacco article is applied thereto as it was heretofore the case.

It is another object of the present invention to provide means conducive to an easy manipulation of the lighter housing which may be made from resilient, liquid-tight and acid-proof material, whereby upon compressing of the housing air-vapor mixture may be readily directed to the lighter element to bring about incandescence thereof.

lt is a further object of the present invention to provide means offering the possibility of readily and conveniently assembling the few parts of which the novel lighter consists and the replacements of any parts thereof, if necessary, the manufacturing cost of the lighter being considerably reduced in comparison with lighters of this type heretofore placed on the market as said parts need no soldering nor any other bonding or fastening means to secure the parts in assembled condition.

Yet a further object of the present invention is to provide means conducive to a simplified construction of the lighter of the aforesaid ltype, which is absolutely safe in operation and avoids loss of lighter uid employed in connection with the action of the lighter.

Still another object of the present invention is to provide means avouching efficient operation of valve vmeans built into the lighter, whereby the lighter may be handled by even an unskilled person and without any danger while being carried around in a purse or pocket by said person.

These and other objects of the invention will become further apparent from the following detailed description, reference being made to the accompanying drawing showing preferred embodiments of the invention.

In the drawing:

Fig. l is a longitudinal sectional view of the lighter embodying the invention;

Fig. 2 is the top plan of the lighter of Fig. l;

Fig. 3 is a top plan view of a specific detail of the lighter referred to in this specification;

Fig. 4 shows in perspective the lighter in its operable condition with a cigarette applied thereto.

Fig. 5 is a side elevational view, partly in section, of the upper portion of the lighter shown in inoperative condition.

Referring now more particularrly to the drawing, there is shown in Fig. l a housing made from known compressible and resilient plastic and like non-metallic material, such as polyethylene composition having the ribs 11 which in this instance, extend in crosswise direction of housing 10.

These ribs may also run in lengthwise direction of the nited States Patent O 'ice housing, if desired, to afford the necessary stiffness to the housing body. On the bottom of the housing 10 and therewithin there ispositioned a lower wire mesh piece 12 on and above which extend lluid absorbent means 13 either in loose or compact form, an upper wire mesh piece 14 being positioned above said absorbent meansto space the latter from the inner surface of upper wall 19 of housing 10. Housing 10 has an extension in the form of a hollow neck 15, which may be provided with outer threads 16 or similar means for the engagement with corresponding threads 17 of a cap member 18.

Through top wall 19 of housing 10 pass a plurality o minute perforations 20 adapted to provide inlet means for fresh air entering the interior of housing 10. Cap member 18 is provided at its lower end with a flange or skirt 21 constructed to overlie perfor-ations 20 and to close the same when the lighter is not in operation. When displacing cap 18 along threads 16 of neck 15, flange 21 will be lifted toa position, as indicated in dotted lines 21a, while the upper end 22 of cap 18 will assume a position as indicated at 22a.

Within the interior of neck 15, there is located a metallic cup-shaped member 25 which has a bottom opening 24 in which is inserted a tubular element 26, which fits tightly in central opening 24 of cup member 25. Further affixed to the outer surface of tubular element 26 is a rubber gasket 27 which is sandwiched between an upper metal disc 28 and a lower metal washer 29, said disc- shaped parts 27 and 29 tightly fitting onto the outer surface of tubular element 26.

On the lowermost end of the aforesaid tubular element 26 there is attached spring 30 for a purpose about to be described. Within cup-shaped member 25 there are seated between upper and lowerwire mesh members 31, 32 catalytic means 33 made of known material which according to the invention consists of a plurality of doughnut-shaped catalytic elements 33a, 33h, 33e and 33d.

These elements 33a to 33d function in unison, having sufcient space therebetween to let vapor-air mixture from tubular element 26 pass through them, in order to create incandescence of said elements or at least some of them and, to thereby assure always operativeness of the catalytic means of the lighter, when the housing is repeatedly compressed by'an operator.

Fitted within neck 15 and tightly engaging the inner wall thereof is a reinforcement in the form of a cylindrical member 34 made of thin-walled metal provided with a bottom 35 on which a rubber washer 36 is seated. This rubber washer 36 has a projection 38 forming a spacer member to keep upper wire mesh piece or layer 14 out of contact with vapor-air mixture inlet 37, as is well observed.

A lateral cut out or inlet 37 in bottom 35 ensures that the aforesaid vapor-air mixture communicates with and ascends from within housing 10 through wire mesh piece 14 into the interior of said cylindrical member 34, whence said air-vapor mixture enters through tube 26 under pressure for contact with said catalytic means 33.

When the cap-shaped member 18 is seated with its ange 21 in contact with said perforations 20, it will be well understood that the cover 40, which is omitted in Fig. l abuts against and moves cup-shaped container 25 together with tubular member 26 and gasket 27 in downward direction against the action of the spring 30, so that the lowermost end of tubular member 26 is forced against the rubber washer 36 and thus prevents any further discharge of vapor and air mixture from inlet means 37 and thereby protects said catalytic means 33.

ln such inoperative position of the cup-shaped member 25 of the lighter and the aforesaid catalytic means 33 are out of contact with the vap'orair mixture, of which a small quantity may remain within the duid-tight space defined by washer 36 and gasket 27.

lf the lighter is operated without a cover 4() proper, or if the latter has been removed, shoulder or projection 39 extending inwardly from the inner wall of cap-shaped member 18 abuts against the upper end of said cup-shaped member 25 and will entrain and push the latter together with tubular element 26 in downward direction according to arrow A (Fig. 5), in which said cap member 18 engages with its harige the top wall 19 of the lighter housing, and the lower end of tubular element 26 engages the rubiber washer 35 to shut oir' the supply of vapor-air mixture to the catalytic or incandescence producing means 33.

Instead of screw threads 16, 17 any known frictional or taper means may be employed to tightly and displaceably engage cap-shaped member t8 with neck t5 of the housing 1).

lt can thus be Seen, that there has been provided according to the invention a lighter structure having incandescence producing means, a housing for containing a fuel, said housing having air inlet means and being made of a plastic, resilient and compressible material adapted upon manual compression and release to produce suction and compression actions relative to said fuel within said housing, and means carried by said housing for directing vapors from said fuel when contained in said housing and further air sucked through said air inlet means into said housing for Contact with said incandescence producing means, thereby enabling lighting a `cigarette and like smoking article when same is brought into Contact with said latter means.

Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:
