Application December 2 3 Claims. 1

This invention relates to a lighter kprimarily adapted for cigars and cigarets and particularly to an improved lighter having inner and outer casing sections arranged for telescopic movement relative to one another.

rihe invention is particularly adapted for cigar and cigar-et lighters of the character having two sliding telescoping casing sections arranged to provide a flame chamber which is opened when the sections are telescoped in one direction and closes the chamber when the sections are telescoped in the opposite direction. The features of the invention, although particularly adapted for the telescoping type of lighter hereinabove mentioned, are also applicable to other types of lighters.

An important feature of the invention, particularly as it applies to lighters having telescoping casing sections, is the provision of the llame producing mechanism which is responsive to the movement of the casing sections in the chamber opening direction to produce an igniting spark and which is so structurally related to the casing sections that when the lighter moves in the opposite direction the mechanism serves in a novel manner to limit the movement of the sections in chamber closing direction. The sparking mechanism is carried by one of the telescoping sections and comprises a pivoted assembly including a rotatable friction wheel and novel means operatively coupled to the telescopingsections for eilecting swinging movement of the asseni ly and rotation. oi the friction wheel when the two casing sections move relatively with respeot to one another.

Another important feature of the inventionk is the provision or" means for circulating air linto and out of the name chamber during the time it is closed so as to reduce the moisture content thereof. Associated with the means for providing such circulation is a novel guard or shield member on the outer casing section which provides a passage opening adjacent at least one of the ends or". the device and communicating with the interior of' the lighter. Novel means is Iprovided which is responsive to the telescopic action of the casing sections to induce air to travel through the and assure circulation of fresh air into the interior of the device.

The parts i the device are relatively simple in construction and are adapted lfor economical manufacture and rapid assembly. An important feature of the invention is the arrangement and location of these parts such that the `device may be readily assembledat minimum labor and disu, i949, Serial No. 134,643

An illustrated embodiment of the invention is shown in the drawings having the body or shell thereof composed oi two telescopng casing members or sections capable of contractible and extensible movement between two extreme positions. In one position a chamber is opened from which issues a flame for lighting purpose. ln the other position the name chamber is substantially closed and all operating parts of the device are protectingly enclosed within the two casing sections, However, even in the closed position oi the parts, provision is made for circulating air into and out of the flame chamber in order to reduce the moisture content thereof and secure better performance oi the flame .produeing parts. The lighter of the present invention is also so designed that certain moving parts thereof serve to hold the two telescoping sections from complete separation thereby eliminating the necessity of providing a special stop for the purpose4 Referring particularly to the drawings, the outer casing section or member is indicated at IIJ and the inner casing section or member at I2. The two casing members telescopically t one another and as shown are of cylindrical formation. However, it is understood that they may be of elliptical or of other non-circular cross sectional formation if desired. One end of the outer casing section IG is closed by a screw threaded cap I4. The opposite end of the outer section I is open, and in any extended position of the parts one end of the inner section I2 projects therefrom as shown in Fig. l. This last end of the inner section I2 is normally closed by a removable discshaped cover plate I6 having an external key or coin receiving notch I8 to facilitate turning thereof. The opposite or inner end of the casing section I2 is closed by a cap 26, the central expanse of which is convexly curved or domeshaped as shown for the purpose of providing clearance for a moving part of the device. The flat peripheral margin of the cap 28 is shaped for intertting engagement with the inner end of the casing section I2 as shown in Figs. 1 and 2.

The left end of the device as viewed in Figs. 1 and 2 between the two caps I4 and 20 forms a substantially closed chamber in which is disposed a coiled spring 22. The coiled spring is seated at its inner end on the peripheral margin of the cap 28 and at its opposite end upon a resilient pad 24 of rubber or the like which lies flat against the outer end wall of the cap I4. The spring is under compression and exerts a force on the two casing sections tending to move them to the extended position shown in Fig. 1. In Fig. 2 the parts are shown in contracted but flame emitting position in which the spring 22 is in a compressed state. The pad 24 cooperates with a projection 26 on the dome portion of the cap 20 to limit the contractible movement of the parts and to lessen the shock of engagement as the two telescoping sections reach this limit of movement.

The inner casing member I2 is divided interiorly into two separate chambers by a wall 28 which is located approximately midway between the opposite ends thereof. |This dividing wall cooperates with the cover plate I6 to form a chamber for containing the customary fuel saturated material 30, such as cotton, and the major portion of the wick 32. The dividing wall 28 cooperates with the dome-shaped cap 20 in the opposite end of the device toform a flame producing and emitting chamber. The wick 32 extends through the wall 28 and into the flame chamber. It is supported as it passes through the wall by means of a short sleeve portion or collar 34, the axis of which is inclined as shown at an acute angle to the longitudinal median line of the device for a purpose hereinafter described.

The two casing members I6 and I2 are each cut away or otherwise shaped to form side wall openings or apertures which in one extreme position of the telescoping movement of the members are in registration with one another and in the other extreme position of the movement of the members are staggered with respect to one another and therefore completely out of registration. The aperture in the side of the outer casing member I6 is indicated at 36 and as shown in Figs. 4 and 5 the aperture has a greater peripheral dimension than its axial dimension. The

aperture in the side of the inner member l2 is indicated at 38 and corresponds in size to the aperture 38 of the outer member. In the embodiment of the invention illustrated herein the two apertures are in the form of semi-circular slots adapted to completely register in the fully contracted position of the casing members as shown in Fig. 2 and to be completely out of registration in the fully extended position of the members as shown in Fig. l. The aperture 38 of the inner member I2 is located adjacent to the dividing wall 28 but on the flame chamber side thereof. The aperture 36 for the outer member is located closer to the end cap I4 of the body than to the opposite end, and the arrangement is such that in the fully contracted position of the parts, and

` in positions approaching that condition, the two apertures 36 and 38 open the llame chamber to the outside.

'Located in the flame chamber is a movable assembly for igniting the wick 32. The assembly is pivoted on a cross shaft or pin 4U for swinging movement. The pin is supported by the inner casing member I 2 and for this purpose the dividing wall 28 is provided with two correspondingly shaped longitudinal projecting portions or journal mountings 42-42 which extend in side by side slightly spaced apart relation. The two portions 42-42 and the wall 28 may form an integral one-piece construction as shown in Fig. 5, The two projecting portions 42-42 of the dividing wall are provided with aligned bores 44-44 in which the ends of the pivot pin 40 are received. Thus mounted, the axis of the pin coincides with a chord line of the inner casing section I2 approximately midway between the center and the periphery thereof as shown in Fig. 3 and bridges the space between the two projecting portions 42-52. The projecting portions I2-42 are curved on their outer surfaces to conform with the inner periphery of the casing section I2 and snugly nt the same. The inner section I2 is provided With a circular aperture 46 on each side thereof which are adapted to align with the projecting portions. In the assembled position of the parts, the ends of the pivot pin 40 lie within the bores 44-44 and partially within the apertures 46-46 of the inner casing section I2 as shown in Fig. 3. The pin is maintained in this position by the complete overlapping of the outer casing section I0 over the apertures 46-46.

The assembly within the flame chamber for igniting the wick is in general composed of conventional elements for this purpose but the elements themselves are constructed and arranged in a distinctly novel manner to gain certain advantages. The assembly comprises a friction Wheel 48 journaled on the pivot pin 40 intermediate the projections 42-42, a ratchet wheel 50 fixed to one side of the friction wheel 48 and similarly journaled on the pivot pin 40, and a U-shaped enclosure for the two wheels generally indicated at 52 in Fig. 5 and comprising the spaced side wall portions 54 and a closed end portion 56 remote from the pivot pin 40. The side wall portions 54-54 of the U-shaped member are pivotally mounted on the pin 40 on the opposite sides of the friction wheel 48 and the ratchet wheel 5D and between the same and the projecting portions 42-42 as shown in Fig. 3. A pawl 58 is carried by one of the side walls 54 of the U-shaped member as shown in Figs. 1 and 6. This pawl engages the teeth of the ratchet wheel 5I) and limits the rotation thereof and the friction wheel to one direction.

The extremities of the side wall members 54-54 of the pivotal assembly 52 are shaped with an arcuate set of teeth Si] which project beyond the friction wheel as shown in Figs. 3 and 6 and form segmental portions of a pinion. The closed end Eli of the U-shaped member receives a iiame extinguisher or snuffer 62 of cupshaped formation which is arranged as shown in Fig. 1 to abut the collar :it through which the wick 32 projects. The closed end of the U-shaped member may be crimped around the snuier as shown in Fig. 3 to secure the same permanently in place against lateral displacement. The snuffer 62 and the collar 3ft are arranged such that. in one position of the swinging movement of the former it abuts the end of the collar which projects into the name chamber. This abutment not only serves to form a subsidiary chamber in the device completely sealing the igniting end of the wick but also as a stop limiting further swinging movement of the snuiier $.72.

The inner casing section l2 is provided with a slightly longitudially elongated slot 64 on the side thereof opposite to the aperture 38 and in juxtaposition to the teeth B of the U-shaped member. The extremities of the U-shaped member are arranged to project a distance such that the teeth thereof during the swinging movement of the assembly are carried into the slot 64 and beyond the outer peripheral surface of the casing section l2. Cooperating with these teeth and forming a part of the exterior casing section ID is a rack. The rack is shown in Figs. l to 7 inclusive as formed into the side wall portion of the outer casing section l0 at 66 in such a position that it will move across the slot tft and into engagement with the teeth 60 of the pivotal assembly. Thus, contractible movement of the two casing sections l0 and l2 as shown by a comparison of Figs. 1 and 2 will cause the rack (it to slide past the slot 64 and successively engage the teeth B and swing the assembly in a counter-clockwise direction. This moves the snuffer 62 away from the projecting end of ythe wick 32 and exposes the latter thereagainst in the flame chamber.

Carried by the device are generally conventional elements for producing sparks for igniting the wick. For this purpose, there is provided a tube 63 extending through the cotton containing chamber from one end to the other end thereof and carrying in projecting relationship to its inner end a dint '50. The latter bears against the friction wheel t8 and, as in conventional practice, rotation of the latter against the stationary flint will produce sparks for igniting the wick. The flint "it is spring pressed in the usual manner by the provision of a plunger 'i2 bearing against the base of the flint and a coil spring 'i4 in the tube 62. The outer end of the tube 58 adjacent to the removable cap It is provided with a small closure member it threaded thereinto for removing the spring and plunger in order to replace a new flint in the device. The closure member 'l5 becomes accessible after removal of the cover plate i6.

An important feature of the invention is the provision of means for circulating air into the name chamber when the latter is closed and the device is in inoperative position such as that illustrated in Figs. 1 and 4. It has been found, particularly in humid weather, that it is difficult to ignite these types of lighters. After the flame has been extinguished and the flame chamber closed, .the moisture content thereof is likely to deposit on the friction wheel and the iiint and impair if not entirely render these elements inoperable. This feature of the invention under consideration enables air to circulate into and out of the closed iiame chamber so as to reduce the moisture content thereof. For this purpose there is provided an aperture 18 in the outer casing section I0 which in the closed position of the flame chamber registers with an opening in the inner casing section I2, such as the opening 64, in order to provide circulation of air int'o and out of the flame chamber. As shown in Fig. 1 wherein the flame chamber is closed the port 'I8 is in registration with the slot 64 permitting the air to llow into and out of the flame chamber. Of importance is the location of the port 18 immediately adjacent to the peripheral portion of the friction wheel which will strike the flint as shown in Fig. 1. When the device is operated to igniting position such as shown in Fig. 2, the port 18 is shifted to a position staggered with respect to the slot 6A.

To conceal the air owing port i8 in order to prevent it from being accidentally clogged and at the same time providing means for causing a positive flow of air therethrough, the device is provided with an exterior cody portion 8i) in the form of an elongated slightly channel shaped strip of metal which is integrally connected or otherwise secured to the outside casing section Il). The channel shaped formation of the strip provides an elongated passage 'f3.2 running the length thereof and opened at either or both ends thereof. This passage communicates with the port it and when the latter is in registration with the slot E4 it also communicates with the interior of the flame chamber when the latter is closed. The channel shaped strip Bil overlies both the port 'it and the rack 5t concealing both of these elements from view.

A small port 84 is provided in the outer casing section l0 which communicates with the chamber in which the coil spring 22 is housed. This port opens into the passage 52 formed by the strip 85 and serves to permit the free flow of air into and out of the spring chamber as the chamber is expanded and contracted without resistance. When the spring chamber is contracted to the position shown in Fig. 2 the air expelled therefrom fiows through the port Sii and is discharged into the passage G2. When the device is permitted to return to normal ciosed position such as shown in Fig. 1, the port im permits air to enter the spring chamber. As the parts approach the final closed position shown in Fig. 1 the port 13 registers with the slot 54 and the suction created by the expansion of the spring chamber is communicated by the passage 82 to the port lil. Thus a movement of airis set up in the passage 2 which induces the air in the ila-me chamber to Aiiow out of the port it during the closing movements of the parts.

Figs. 8, 9 and 10 illustrate a modication of the invention wherein7 in place of the pinion and rack teeth heretofore described for operating the spark wheel .68, there is provided a connecting element secured directly to the pivoted assembly and to one of the Imovable casing secconnection, although shown incorporated in a tions of the lighter. This particular form of lighter having telescoping casing sectionsy is also adaptable to other forms of lighters.

Referring particulary to Figs. 8, 9 and 10, the

parts of the lighter Corresponding to the same parts described in the .preceding embodiment of the invention are referred to by the same reference numerals. As shown in Figs. 8 and 9, each side wall 54 of the snuffer carrying member 52 is provided with a small projecting ear 86 located in corresponding positions thereon and serving as a support for a transversely extending pin 88 shown in Fig. 10. A similar set of ears are provided on the inner face of the shield 8B, as indicated at 8D in Figs. 8, 9 and 10. This last set of ears are disposed opposite to one another and serve as supports for a pin 92 bridging the space therebetween. The outer casing member ID is provided with a longitudinal elongated slot 94 which, as shown in Figs. 8 and 9, is adapted to partially overlap the aperture B4 of the inner` casing section between the two extreme positions of the parts. Thus overlapping, the two apertures gli and 6ft provide an opening from the interior of the lighter to the inside face of the shield 82 through which extends a connecting element for pivoting the assembly including the spark wheel and the snuer. This connecting element is in the form of a thin flat slightly ilexible metallic band S35 having one end thereof curled about the pin 38 for securement thereto and the opposite end thereof similarly curled about the pin 92 for securement thereto. It is evident that as a result of this construction the connecting band 9S will cause the spark wheel and the assembly associated therewith to swing around the axis of the pin i4 upon contractual telescoping movement of the two casing sections.

In Fig. 8 the casing sections ifi and i2 are in their normally closed position with the operating parts in position corresponding to that shown in Fig. 1. Upon contractual telescoping movement of the two casing sections, the shield 80 moves jointly with the outer casing section ID and exerts a pull on the connecting band SB causing the same to rotate the spark wheel and the assembly associated therewith in a counterclockwise direction to the position shown in Fig. 9. In this latter position, the wick 32 is exposed and the dame chamber of the casing 'sections is opened to permit the ame produced by the wick to rise therefrom. In either position of the parts illustrated in Figs. 8 and 9, the connecting band 96 extends through the overlapping apertures 94 and G4 and by virtue of its iexible and relatively thin flat condition it may be easily accommodated in the conned space between the inner and outer casing sections and the shield 8G, The spring 22 will return the parts to the condition shown in Fig. 8 upon release of finger pressure on opposite ends of the lighter and the connecting band dll will swing the pivoted assembly to its initial starting position shown in Fig. 8.
