nited States The present invention relates generally to the field of lighting devices, and more particularly to an improved cigarette lighter.

A major object of the present invention is to provide a pocket lighter that is free of pivotally supported or hinged covers which are subject to wear and breakage.

A further object of the invention is to provide a cigarette lighter of simplified structure that is compact and durable, and substantially impervious to damage should it be inadvertently dropped.

A still further object of the invention is to provide a pocket lighter which `while compact, has substantially greater fuel capacity than lighters currently on the market, requires a minimumof maintenance attention, and may be carried either loosely in the pocket, or easily aixed to a chain or similar flexible member that is connected tothe wearing apparelof the user.

A further object ofthe invention is to provide an imp roved cigar and cigarette lighter which not only has substantial operational advantages over pocket lighters available heretfore,'but one that is distinctive and ornamental in appearance.

These and other objects and advantages ofthe present invention will become apparent from the following d escription of the first and second forms thereof, and from the accompanying drawing illustrating those forms in which;

fuel in a wick Eto provide a flame F. As shown in Figure 1, container A is preferably of elliptical transverse cross section and has a cover G slidably mounted on the exterior surface thereof, which cover is also of ellipticaltransverse cross section. `A stop H is removably aixed to the forward extremity of projection B, and this stop not only serves this function but defines an end portion of the lighter when it is in the normal carrying position shown in this figure.

. In detail, container A includesan elongate first shell 10 of transverse elliptical cross section, one end of which terminates in an end plate 12 (Figures 1 and 2). End plate 12 is preferably of larger transverse area than shell 10 to therebyprovide a continuous outwardly projecting liange 14 that is not only decorative in appearance, but serves as a stop for the rearward movement of cover G, as may be seen in Figure 5. The upper forwardly disposed end portion of shell `10 terminates in a first end piece 16, the edge portion of which is Hush with the exterior surface of container A. The lower edge of end piece 16 develops into a. forwardly extending rigid strip 18, and the forward extremity of this strip turns downwardly to form a second strip 20 that is bent or otherwise formed to provide a thirdstrip 22 which returns'rearwardly parallel to the firstV strip. The rear extremity of strip 22 develops into a second end piece Zit-,that is parallel to first end piece 16 but is disposed forwardly thereof.

Thefirst, second and third strips described above, as well as the secondend 4piece 24, are bondedas by welding ,011 the like, to projection rBand the lower edge portion of shell 1i), as shown in Figures 2 and 4. An opening 2 4 a isforrned in end pieceV 24 from which a cupshaped, member 2,6 of relatively small transverse cross section extends rearwardly. The upper portion of Yend p late 12 is,for r ned with a forwardly extendingboss 28 having a tapped bore 3Q extending therethrough which terminates in the mostrearwardly disposed portion of bos s 28 in a recessed portion 30a` of larger transverse cross-sectional area than that of bore 30. Bore 30 is threadedly engaged by a threaded plug referred to generally by the numeral 32, the structure of which is shown in detail in Figure 2. Plug 32includes a circular plate 34 of a size to permit tl1e snug fit thereof within the confines of recess 30a. This plate also has a threaded member 36 which projects forwardly therefrom that is adapted to be removably disposed in tapped bore 30. yA handle 38, preferably in the form of a bifurcated mernber, is provided that is pivotally supported in a mem- -b er 4i) of U-shaped transverse cross section and ali'ixed to the rear surface of plate 34. A second boss 42 is formed on the forward interior surface of the lower portion of end plate 12, and a tapped bore 44 is formed in this boss,

, A small diameter tube 46 extends forwardly and upwardly from the forward extremity of bore 44, and terminates in a flanged end 48 that projects through an opening 50 formed in second strip 18. An externally threaded plug 52 is threadedly inserted within the confines of bore 44, and this plug preferably has a transverse slot S4 formed on the rear face thereof which is adapted to be engaged by a ten-cent piece or small screw driver to permit unscrewing of the plug from bore 44.

A helical spring 55 that is at all times under cornpression is situated within the confines of tube 46 and at all times tends to urge flint D upwardly into contact with the spark-generating wheel C. A slightly flanged opening 56 is formed in second strip 18 forwardly from wheel C, and wick E projects through this opening, as best seen in Figure 2.

A `third inwardly extending boss `5,8 is formed in the forward interior portion of projection B and a tapped bore 60 extends downwardly therein that may be engaged by a screw 62. Stop H (Figure 3) includes a rigid supporting member 64 in which an opening 66 is formed and through which screw 62 can extend downwardly to engage tapped bore 60 to hold stop H in the position shown in Figure 2. The forward extremity of member 64 is afiixed to an elliptical first segment 68 of sheet material.

An elliptical section 70 extends rearwardly from segment 68 and the free ends thereof terminate in forwardly and downwardly tapering edges 72. Two parallel, laterally spaced side members 76 are provided, the rearwardly and downwardly disposed edges of which are affixed to second strip 18. The external surfaces of side members 76 are flush with the external surface of container A. Two horizontally aligned bores are formed in members 76 through which a shaft 78 projects. Wheel C is of the type commonly utilized in cigarette lighters having a knurled circumferentially extending surface 80 and a central bore extending transversely therethrough in which a brass sleeve 82, or other tubular insert, is mounted to freely and rotatably support wheel C on shaft 78. Two identical tubular sleeves 84 are mounted on shaft 78 on opposite sides of wheel C. The outer ends of sleeves 78 bear against the interior surfaces of side member 76 and the interior ends of these sleeves are positioned adjacent to wheel C. Sleeves 84 serve as spacers to prevent any appreciable lateral movement of wheel C on shaft 78. Side members 76, as can best be seen in Figures 2 and 4, extend forwardly on second strip 18, with the foremost vertical edges 76a thereof abutting against the lower opposing edge portions 70a of stop H.

The lower exterior surface of strip 18 supports a longitudinally extending member 86 which includes a web 88 having identical longitudinally extending guides 93 formed on or supported from opposite edges thereof. Each of the guides 93 are of L-shaped transverse cross section.

The cover G, as shown in Figures l, 2 and 4, is an elongate second shell of elliptical transverse cross section, and two oppositely disposed, longitudinally extending rails 92 are provided on the interior surface thereof that slidably engage guides 93. Cover G is of such transverse cross section as to permit snug, slidable engagement thereof with the exterior surface of a at raised band 91 that encircles container A (Figure 5). The purpose of band 91 is to prevent scratching or marring of container A as a result of repeated rearward and forward sliding movement of cover G. The upwardly and forwardly disposed portion 88 of cover G is cut away to such an extent that the side wall 70 and segment 68 thereof define a portion of the cover when it is in the foremost position on container A as seen in Figure 1. A second elliptical segment 90 formed of a rigid sheet material is bonded, welded or otherwise aiiixed to the forward edges of cover G (Figures 1 and 6), and as best shown in Figure 2, together with segment 68 cooperatively provides a second end plate generally designated by the letter I of the lighter when it is in the position shown in Figure 1.

Cover G at all times tends to remain in the forward position shown in Figure l due to a compressed helical spring 94 situated within the confines thereof. The rearwardly disposed end portions of spring 94 are situated within the cavity-.defining portion 26 of the third strip 24, and the forward end of spring 94 abuts against the interior surface of segment 90 and is situated within the confines of a ring 96 afiixed thereto. Ring 96. serves to prevent inadvertent displacement of the forward end of spring 94 out -of abutment with the interior surface of segment 90. It will be obvious that the device is assembled by placing spring 94 within the confines of cover G (Figure 2), slidably inserting the cover onto container A, then causing screw 62 to project through bore 66 4 and engage tapped bore 60 to hold the stop H in the position shown in Figures l, 2 and 5.

The present invention is used by first disengaging the threaded member 36 from the tapped bore 30 in order to pour fuel into the confines of container A therethrough onto absorbent cotton or other absorbent medium (not shown) situated therein. The liquid fuel passes from this absorbent material to the wick E. A fiint D is placed within the confines of tube 46 and moved upwardly therein by application of longitudinal force on spring 56. After spring 56 is fully inserted within the confines of tube 46 it is maintained therein by causing plug 52 to threadedly engage tapped bore 44.

When it is desired to use the invention above described, the lighter is grasped in the hand and the thumb placed in Contact with the lower rear portion of end plate 12, with the forelinger contacting the exterior surface of segment 90. The thumb and forefinger are then cooperatively moved to cause rearward movement of cover G relative to container A until the rear edge of the cover abuts against the forward edge of flange 14. It is then possible to manually rotate wheel C to generate sparks thereby as the wheel frictionally contacts fiint D to ignite wick E and provide the fiame F. Wick E is preferably formed of asbestos. To facilitate clean combustion of the fuel burning from wick E, a number of perforations 98 are formed in the forward portion of side members 76 to provide adequate oxygen for combustion of the fuel.

It will be particularly noted that while the first form of the device permits free movement of the cover from the closed position shown in Figure l to the open position shown in Figure 5, this movement is made possible by virtue of guides 93 and rails 92 that are durably vmaintained in fixed longitudinally extending positions, and are sufficiently heavy, as well as protected to prevent deformation of cover G and container A should the invention be inadvertently dropped, receive a sharp blow, or the like.

This construction avoids the necessity of pins, hinges orl other delicate mechanisms which are subject to wear and prone to get out of order, and as a result thereof the present invention requires substantially no maintenance attention. Also, it will be noted that within the confines of container A projection B provides additional space wherein a substantial quantity of liquid fuel may be disposed whereby the lighter of the present invention doesI not require the frequent fueling so commonly required with present-day cigarette lighters which normally have but a limited fuel capacity.

The second form of the invention is in many respects identical structurally to the first form of the device. However, the second form has an additional operational advantage in that as the cover thereof is moved rearwardly relative to the container, this movement causes automatic ignition of the wick. To illustrate the susceptibility of the invention to fabrication in a number of different styles, the second form thereof is shown in rectangular cross section rather than the elliptical cross section employed in the first form of the device. Inasmuch as the majority of the components comprising the second form of the invention are the same as utilized in the first form thereof, those components common to the first form are identified by the same identifying numerals used in describing the first form, except that a prime is added thereto for the purpose of clarity.

In Figure 7 it will be seen that as in the first forrn of the invention, a liquid fuel container A' is provided that has a forwardly extending projection B that rotatably supports a wheel C', which when rotated in frictional contact with a fiint D' causes sparks to be emitted which ignite the fuel in a wick E' to give a flame F'. The fabrication of container A is identical to the structure of container A previously described, except that container A is rectangular in transverse cross section. The stop H is likewise identical to stop H except that stop H is also of rectangular cross section.

Cover Gf is identical to the cover G previuslyde'scibd except that cover G' 'is' of rectangular configuration and adownwardly extending rigid member 100 is aliixed to the upperforward interior surface thereof which supports a rearwardly extending rack 102 that is separated by a space 104 from' the upper interior surface of cover A. In the second form of thev invention container A' is modified in that the end piece 16' terminates a substantial distance below the upper interior-portion of shell and develops into a rearwardly extending flat member 106, the rear end of which turns upwardly at approximately 90 to form a second member 108. Members 106 and 108 are welded or otherwise rigidly affixed to the' side walls of shell 10. A portionr110 of'shell 10' extends forwardly over the first rigidrmember 106, and serves to define aniinner compartment 1.12 open at the front end in which the rack 102 is situated when cover G'` is in the rearwardly disposed 'position shown in Figure 7. p p l v The flint wheel C used in the first form of the invention is replaced by the flint wheel assembly 114 shown in Figure 9 and in exploded perspective in Figure l0. Assembly 114 includes a shaft 116 that is held in a fixed position between the side members 76. One end of shaft 116 is encircled by a compressed helical spring 118 which bears against a ring-shaped side wall 120 of a pinion 122 that is aflixed to one side of'a circular plate 124. Plate 124, as well as pinion 122, h as a central bore 126 extending therethrough that is defined by a cylindrical surface which rotatably engages shaft 116. The side of plate 124 opposite thaton which the pinion 122 is mounted is provided with a"`nu`mb'er of circumferentially spaced teeth 128.

Teeth 128 are so spaced that each tooth will engage one of a number of wedge-shaped cavitiesr130 formed on the interior surface of a second plate 132. Plate 132 has a bore 134 formed therein that is coaxially alignable with bore 126 and through which shaft 116 extends. On the side of plate 132 opposite that in which the cavities 130 are formed is provided with an outwardly projecting boss 136 which defines a ring-shaped exterior surface that rotatab-ly engages the inner surface of one of the side Wall members 76', as best seen in Figure 9. A ring-shaped flange 138 projects from the outer circumferential edge of plate 132, and this flange is serrated or knurled to cause sparks when in frictional contact with flint D.

When rack 102 is moved relative to pinion 122 by rearward movement of cover G', relative to container A', the teeth 128 are rotated in such a direction as to drivably engage the cavities 130 and cause rotation of plate 132 as well as the flange 138. This rotation of the flange causes the emission of sparks due to contact with flint D whereby wick E is lighted. However, upon release of pressure from cover G, the spring 94 tends to expand to move the cover forwardly into the position shown in Figure 8. During this movement rack 102 rotates pinion 122, but the rotation -of teeth 128 is then in a `direction wherein they merely slide over the depressions 130 without driving the plate 132 or flange 138.

Thus, as the cover G returns to the fully extended forward position shown in Figure 7 there is no tendency of the plate 132 or flange 138 to rotate, and the flame F' previously effected by ignition of the fuel in wick E' is extinguished due to lack of oxygen as cover G' assumes the closed position shown in Figure 6. Upon rearward movement of cover G relative to container A as above mentioned, the operation is again repeated, with the wick being relighted to provide the flame F. The handle 32 is preferably of square transverse cross section and is adapted to removably engage slot 54 to permit unscrewing of plug 52.

Although my invention is fully capable of achieving the results and providing the advantages hereinbefore mentioned, it is to be understood that it is merely the presently preferred embodiments thereof, and that I do gassen not mean-to be limited to the details of coijs't'r'ctinabove described other than as defined in the appended claims.
