Cl. 431-142 Claims ABSTRACT OF THE DISCLOSURE Background of the invention The invention relates to cigar and cigarette lighters having replaceable reservoirs of gas, such as butane, as a fuel supply.

Summary of the invention The invention resides in a novel mounting of the gas reservoir and ignition means within a frame member enclosed between two outer casing halves which in turn, are releasably secured to said frame member by at least one moveable bolt member mounted on said continuous member and actuated by a moveable control member extending through said outer casing halves and the frame member to retain said halves, reservoir and its mounting member in fixed relation.

One object of the invention is to provide a lighter assembly of the character described wherein the said moveable control member in locking position retains both outer casing halves in assembled relation and in released position releases the casing halves for separation.

Another object of the invention is to provide means on said casings for cooperation with said moveable control member for initial separation of the casing member by movement in one direction and for locking up the casing members against separation by movement in the opposite direction.

Description of the drawing FIGURE 1 shows the lighter in side elevation with a portion of the casing broken away to show the relation of the moveable control member with the reservoir mounting member.

FIGURE 8 shows the relation of the control member to the casing halves, as positioned in FIGURE 7 taken on lines VHI--VIII of FIGURE 7.

Description of the preferred embodiments Referring now to FIGURES 1 to 4 of the drawing, the lighter outer casing is comprised of the members 1 and 2, as best shown in FIGURES 1 and 2. Each member 1 and 2, comprises an outer face portion and opposing peripheral flanges 1 and 2 respectively, to complete the enclosure. At the top edge of the lighter, FIGURE 2, said flanges 1 and 2 are provided with semi-arcuate matching openings providing an outlet 6 for the lighter flame. Additionally, each flanges 1 and 2 and the casing members 1 and 2 are cut out, as at 7, to expose the conventional ignition control mechanism 4.

Disposed between the casing members 1 and 2, as best shown in FIGURES 3 and 4, is a non-continuous band shaped member 3 whose end portions may be suitably connected, as shown, with the ignition control mechanism 4 and whose intermediate position is enclosed by the casing bottom flanges 1 and 2*. The gaseous fuel reservoir 5 is suitably connected with said control mechanism 4 and is also disposed within band shaped member 3.

Means for retaining the two casing members 1 and 2 in assembled relation with the band 3 and for releasing the members 1 and 2 therefrom for separation to provide access to the ignition means 4 and reservoir 5 are best shown in FIGURES 3 and 4 of the drawing. Casing members 1 and 2 each have, at one side of the lighter, slotted opening-s 16 similar to openings 26 and 26' of FIGURE 8 of the drawing. Such openings 16 and 16' may terminate in similar arcuate end portions such as 26 and 26 of FIGURE 6, or one arcuate end portion in casing 1 may be shaped similar to 26 of FIGURE 6. Suitable shaped openings 15 are also provided in the underlying portion of band 3 for reception of push button 17. Overlying said openings 16, 16' of the casing members 1 and 2 is a slideable push button 17 having depending therefrom a shank portion 14 extending through openings 15 in band 3 and terminating in a shoe or wedging member 13.

As shown in FIGURE 3 the push button portion 17 and shoe member 13 are of greater linear length and width than the slotted band and easing

openings

15 and 16 respectively. Disposed within the band member 3 is a convex leaf spring member 10 of a width to overlap flanges 1 and 2 of the casing member 1 and 2 and fixed at one end to the adjacent face of band 3 by a suitable member 11. The opposite end of member 10 is disposed between the adjacent faces of member 13 and band 3. Intermediate the ends of spring member 10 are secured a pair of transversely spaced pin members 9 disposed in suitable openings 12 in band 3 and aligned with suitable recesses 8 in the adjacent casing flange portions 1 and 2*.

Referring now to FIGURES .3 and 4, the casing halves 1 and 2 as initially assembled upon opposite sides of band 3 with the push button 17 in raised position, as shown in FIGURE .3. The portion 13 of the push button assembly is free of the gas reservoir 5 and the spring 10 is bowed to retract pins 9 to the position of FIGURE 3. Thereafter, the push button 17 is moved in the direction of arrow F (FIGURE 3) to the position shown in FIGURE 4. In so moving, the upper face of portion 13 of the push button assembly moving along the adjacent end of spring 10, deflects springs 10 causing the pins 9 associated therewith to penetrate openings 12 in the band 13 and to engage adjacent recesses 8 in the casing members 1 and 2. Concurrent with this movement of the push button 17, the portion 13 thereof engages the reservoir 5 to lock same and the associated control mechanism 4 in fixed relation to ring 3. Hence the assembly is now locked with the casing members restrained against separation, even if dropped from the hand. Should it be desired to separate the casing members 1 and 2, the push button 17 of FIGURE 4 can be moved in the direction of arrow to return the parts to the position of FIG- URE 3 by releasing spring 10 to retract locking pins 9 from engagement with the casing recesses 8. In this latter position the casing members 1 and 2 can be separated by the fingers to provide access to the gas reservoir and control mechanism 4 for any desired purpose.

Referring now to FIGURES 5 to 8 of the drawings illustrating a modified form of the invention, wherein the casing members 1 and 2 may be identical with the similarly number members of FIGURES 1 to 4, as are the band 3, reservoir 5 and ignition control mechanism 4. FIG-

URES

6 and 8 illustrate the slotting of easing flanges 1 and 2 for reception of the shank portion 14 of push button 17*.

Push button 17 is provided with a shank portion 14 extending through the slotted openings 26 of the casing member flanges 1 and 2 and the slotted opening 15 of the band member 3 Secured to push button shank portion 14 by any suitable means such as pin 28, is slidable shoe member 23 having one end thereof underlying member 4 and the opposite arcuate end 23 extend along the adjacent inner face of band 3 in spaced relation thereto, with the end portion 23 abutting band 3. An arcuate shaped spring member 10, FIGURE 5, has mounted intermediate its ends transversly spaced pins 9 registering with openings through band 3 and adapted to engage recesses 8 in the adjacent face of casing portions 1 and 2". One end of member 10* is suitably attached to ring 3 by spur 11 and the opposite end of member 10 is engaged beneath portion 23 of member 23.

When assembling the casing members 1' and 2 with the ring member 3, one casing member such as 2 may be held in the hand. The ring 3 having assembled therewith the control mechanism 4, reservoir 5, push button 17,

members

23 and 10 may be disposed upon casing section 2 with the push button portion. 14 disposed within slot 26' of member 2 Thereafter casing member 1 may be laid over casing member 2, in matching relation therewith and the button 17* moved downwardly in slots 26-26 of the casing members, as shown in FIG- URE 7. During movement of button 17*, the member 23 moves over member 10 flattening same to advance pins 9 thereon through ring 3 and into engagement with recesses 8 of both casing flanges 1 and 2 At this time stem 14 of the push button, engages with the

bottom portions

26 and 26 and both casing sections 1 and 2 are locked into engagement with ring 3*. Additionally, during movement of push button 1'7 as described, the portion 23 of member 23 has engaged reservoir 5 and holds it against movement within ring 3 During the reverse movement of button 17, as indicated by line 0 of FIGURE 7, the member 23 returns to the position shown in FIGURE 5 and thus releases spring 10 to return to convex form, withdrawing pins 9 from engagement with casing members 1 and 2. During such movement of button 17, portion 14 thereof moving upwardly encounters portion 26 of the slot in casing member 1 and partially separates the casing halves as shown in FIGURE 6. Thereafter casing member 1 may be removed to expose ring 3 and its associated members.
