7 Claims. (Ci. 67- -71) The present invention relates to a lighter for smokers which uses as fuel a liquefied gas such as butane. Lighters of this kind have already been proposed in which the cartridge, provided or not with a sheath or outer case,

forming the body of the lighter is obturated, in storage position, by a plug engaged in an opening provided with a gasketed joint, supple, cylindrical or toric, made for instance of rubber, while the head of the lighter which is intended to be joined up with the cartridge contains all the lighting mechanism, the valve and the pressure reducer which extends in a gas supply such as a pipe penetrating in the cartridge through the joint; after removing the cap, this pipe can eventually be replaced by a hollow needle penetrating through the plug which forms a membrane and, in such a case, is itself made of a supple rubber.- In :a lighter of this kind, it is necessary to keep coupled the cartridge and the head of the lighter, to prevent the pressure of the gas which is applied upon the head through the gas supply from bringing about the expulsion of this head and the separation in two parts of the lighter. This result is generally obtained by disposing the'whole of the two parts of the lighter, head and. cartridge, in a case made of two pieces.

The device according to the present invention aims at rendering safer and in same timemore flexible the positive connect-ion which must exist between the cartridge and the head of the lighter. and is characterized in that the upper portion of the cartridge and the adjacent portion of the head of the lighter offer on their narrow sides complementary profiles which can penetrate into each other by rotating round the axis of the pipe after its introduction in the cartridge to interconnect the two parts of the lighter.

Through the arrangement of the present invention, as distinguished from even the screw threaded engagement of a cartridge and lighter head, it is possible to form a substantially flat conventional type lighter, since the complementary sides of the cartridgeand lighter head are perfectly aligned when the lighter head and the cartridge are brought into locking engagement. Also, there is ensured complete and immediate coupling of a fuel transferring means between the cartridge and'the lighter head just prior to the slight rotation needed to bring the cartridge and the lighter head into aligned and interlocked engagement. In other. words, interlocking engagement of the lighter head and cartridge are necessarily accom panied by eifective alignment of the two casing parts of the finished lighter as well as by full and eifective coupling of the fuel transfer means between the cartridge and the lighter head.

The assembly thus obtained can in addition be locked either by means of a cover set on the head of the lighter and covering the assembling joint, said cover having, in

arrests Patented Feb. 23, 71965 ICC ture Z'provided with an inlet pipe 3 in which is screwed a gas flow mouth-piece 4: this mouth-piece is provided with a toric or cylindrical gasketed joint 5 into which is inserted, in the storage condition, a plug (not illustrated), which maintains sealed the cartridge until removed, or which may be obturated by a'cap whichcan be perforated. In its operative position, the cartridge 1 is-joined up with a head 6 supporting an abrader wheel '7- and the usual flint (not illustrated) and :a pressure reducer 8 which communicates, on the one hand, with a gas inlet pipe 9 inserted in the mouth-piece 4 through the joint 5 and,'on the other hand, with a valve 1d, the openingof which is controlled by a fork 11 operated by the lever 12 hinged in 13 and supporting the control push button 14.

The upper part of the cartridge 1 presents a central rectangular abutment 15 in the narrow edges of which are provided grooves 16, 16, while the head 6 has, in its lower face, a corresponding rectangular recess 17, in the sides of which are provided ribs 18, 18, the whole forming an assembly ofthe dove tail type. When the gas inlet pipe '9 is engaged in the cartridge 1 by placing enough to cover. the assembling joint 16-18, 16-13,

and has, at its front end a notch 20 into which fits the abrader wheel '7. An aperture 21 is formed at the top of cover 19 to give passage to the push button 14 and an :aperture at the rear end gives access to the adjusting a known way, a notch in front of the valve and the light- 7 ing mechanism, either by means of two checks or small side plates fixed upon 'thecartridge, and also by both means at same time. i

By way of example, a form of embodiment of the invention is described hereafter and illustrated in the annexed drawing.

FIGURE 2 is a side elevation view.

screw 22 of the pressurereducer 8.

Besides, two sidegcheeks, which can also be used as.

trimmings, are fixed on the cartridge: theupper edges of these cheeks cover the assembling joint 16-18, 16-18, and eventually the lower edge of the cover 19 when the two means are used simultaneously. a

' Thefiastening of the cheeks 23, 23', is made by means of a tubular brace 24 fitted in the cartridge and through which pass a screw 25 and a tapped tube 26 forming a nut, the screw 25 and the tube 26 being respectively connected with the cheeks 23, 23'. These cheeks 23, 23', have, in frontof the tubular brace 24, flanged recesses 27, 27', respectively housing the head 28 of the screw 25 and the head 29 of the nut 26; elastic splitted rings or clips secure'the fixation of the screw and 0f the nut on the cheeks but allow them in same time to rotate with respect to these cheeks. e

The two cheeks could also be respectively connected with a socket and a stem interconnected by a bayonet system or'by anysuitab-le device securing an elastic interlocking, such assplitted rings provided with a spring, push button or also they could be kept in place by means of a permanent magnet.

In the case when the locking of the two parts of the initsmedian part, a cover constituted by a small 3 plate 31 hinged at the rear in 32, to allow, on the one hand, the settin of the mechanism and, on the other hand, the adjustment of the pressure reducer and the exchange of the parts, simply by lifting said cover.

In the illustrated standard lighter, the lighter is obtained by means of a knurled nut operated with the thumb, but the invention applies also to any automatic or semi-automatic lighter in which the lighting is obtained by means of a single control organ.

What I claim is:

1. In a lighter for smokers using as fuel a liquefied gas such as butane, a removable cartridge containing said fuel and forming the lower portion of the body of the lighter, a head forming the upper portion of said lighter and including the usual fuel igniting means, together with a controller valve mechanism, a fuel intake pipe extending downwardly from said head when said head is held vertically, said pipe being adapted for insertion into said cartridge through a gasket joint forming part of said cartridge by downward insertion of the pipe into said gasket joint, said cartridge and said head having each relatively wide and narrow sides in transverse cross section and complementary in size to form a complete substantially flat lighter, the upper part of the cartridge and the lower adjacent wall of the head of the lighter having complementary interlocking detent surfaces, said detent surfaces connecting into each other by relative rotation of the head relatively to the cartridge about the axis of said pipe after the vertical movement of said pipe into the cartridge that distance which is required to bring into preliminary lateral alignment the said complementary interlocking detent surfaces, and the said rotation of said head and cartridge relatively to one another bringing the narrow and wide complementary sides of said cartridge and said head into alignment and interconnecting the said two parts of the lighter to form a single substantially flat lighter assembly while preventing the endwise separation of the said cartridge and head.
