United States Patent 3,150,507 LIGHTER MECHANISM James Donald Smith, Stroudsburg, Pa., assignor to Ronson Corporation, Woodbridge, N .J., a corporation of New Jersey Filed Sept. 10, 1962, Ser. No. 222,436 14 Claims. (Cl. 67-7.1)

This invention relates to cigar or cigarette lighters fueled by combustible gases such as butane or propane and in one of its aspects relates more particularly to lighters of the above character in which the lighter is moved from its closed or inoperative position to an open or operative position in one motion. In another aspect it relates to lighters which are so constructed that at least part of the operating mechanism need not be composed of expensive, fire-resistant materials. The invention relates also to the mechanism by which the lighter is actuated.

In the past automatic lighters have been constructed to include a manually operated lid for preventing escape of fuel. Operation of the lighter required that the lid be opened to expose the operative parts. The sparking wheel was then rotated against the flint in a separate motion to produce sparks for the ignition of the lighter fluid. Subsequent lighters have done away with the lid and replaced it with a snufier member which normally covers the burner valve to prevent escape of fuel during non-operating periods. The snulfer is in operative relationship with the sparking wheel and with the finger piece. In these modern lighters pressure on the finger piece activates the sparking wheel and at the same time releases the snuifer to permit escape of fuel into the path of the sparks thus causing ignition.

Modern lighters including a snuffer are more satisfactory than the lid type lighter since they can be operated in one movement. Moreover, it has generally proved possible to produce lighters with less tendency for the fuel to escape because snuifers can be produced which fit very closely over the burner valve. However, the modern lighters, because of the intricate relationship of the working parts, are expensive to produce and quite prone to early failure, especially when subjected to the stresses of every day use.

This invention overcomes the difficulties of prior art devices by providing a lighter which does not require a lid, which can be operated in one motion, which does not require intricate working relationships between the parts and is therefore less expensive to produce and maintain and which moreover can be constructed of generally less expensive materials than has heretofore been thought possible. These and other features and advantages of the invention will appear from the detailed description given below to be read in conjunction with the accompanying drawings which form a part of this specification and illustrate, by way of example, several embodiments of this invention. It should be understood that while the drawings show the lighter as part of a pen, the invention is not so restricted and can in fact be used with a number of other supports as will be apparent to those skilled in the art.

FIG. 17 is a top view of the embodiment shown in FIG. 16.

Referring now to the drawings, FIG. 1 shows a pen lighter generally represented by the numeral 10. The pen is of the conventional type including a reciprocating writing member 11 here shown as the ball point variety. The pen includes upper barrel 12, a lower barrel 13 and a pen clip 14. A lighter of this invention is mounted in the upper barrel.

It will of course be understood that the use of a pen as a base for the lighter mechanism of this invention is illustrative only. It can be mounted on any suitable base, e.g. a candle, a cylinder, a ball, etc.

The lighter includes a rotatable top plate 15 mounting a sparking wheel 16 and a spring leaf snuffer 17. A burner valve generally represented by 18 communicates with a fuel reservoir 19 having a refill valve 20 of the conventional type. The upper barrel itself may of course serve as the fuel reservoir. The top plate is mounted on a body member generally represented by the numeral 21. The body member is somewhat cylindrical in shape and has a longitudinal extension 22 for mounting the pen clip 14. A portion of the cylinder has been cut away to leave an upstanding vertical wall 23 and a lower horizontal base 24. A transverse throughbore 25, extending through the longitudinal extension 22 and the vertical wall 23, communicates with the interior of the lighter and with the pen clip 14. This throughbore carries the pyrophoric material or flint 26. The position of the throughbore must be carefully selected as will be more fully explained hereinafter. The top plate 15 is rotatably mounted on the vertical wall 23 by the pivot pin 27 extending through an opening 28 in the top plate and into a cooperating opening 29 in the vertical wall 23. v

The pen clip 14 is slidably mounted in

guideways

30 and 31 in the longitudinal extension 22. In its upper position the clip impinges against the outer arm 32 of a V-shaped spring generally represented by the numeral 33 constructed of spring steel or equivalent material and coiled about a pivot pin 34 mounted in a longitudinal slot 34a extending the length of the longitudinal extension, the top of said slot leading into the throughbore 25. The inner arm 35 of the spring 33 is formed with a loop 36 somewhat smaller in circumference than the throughbore 25 so that when the clip 14 is in its upper position, the loop 36 of the spring 33 is within the throughbore 25 and biased against the flint 26. It will be noted that this construction provides a very convenient arrangement for replacing the flint.

In the preferred embodiment shown, outer arm 32 is formed with a projection 32:: which aids in maintaining the pen clip 14 in position.

There is also present on the vertical wall 23 a projection 37 for positioning the sparking wheel 16 in a manner to be explained hereinafter.

The lower horizontal base 24 is constructed with an opening 38 in cooperative relationship with an opening 39 in the upper barrel 12 whereby the lighter assembly is aflixed to the upper barrel as by screw 40.

There is also an opening 41 for receiving the burner valve 18. The opening 41 is so placed that the burner valve, when mounted therein is adjacent the sparking wheel and in a substantially direct line with the sparks emitted by the action of the sparking wheel on the flint whereby the fuel escaping from the valve is ignited.

The upper surface 42 of the lower horizontal base 24 is constructed with a guideway 43 having an indent 44 for a purpose to be explained later. The lower surface 45 is constructed with a horizontal guideway 46 extending from the periphery of the body member 21 to the burner valve 18. The adjusting arm 47 of the burner valve extends through the guideway so that it is accessible from the outside to control the height of the flame.

Reference is now made in greater detail to the structure of the top plate and the component parts thereof, especially as these parts are shown in FIGS. 8-14. It will be seen that the top plate is rotatably mounted in the vertical wall 23 by means of the pivot pin 27. It is U-shaped in configuration and the dimensions of the upper leg of the U 48 are such that it forms the whole top surface of the lighter. The vertical section of the U 49 extends downwardly from the upper leg and the lower leg t extends from the lower edge of the vertical section to complete the U. A hollow cylindrical member 51, having a flanged lower section 52, extends upwardly through an opening 53 in the lower leg 50 in direct line with a cooperating opening in the spring leaf snuffer 17, the same having a similar relationship with an opening 54 in the sparking wheel. The opening 54 is somewhat larger in diameter than the outside diameter of the cylindrical member so that the sparking wheel is rotatable about the cylindrical member. The lower flange is of larger diameter than the opening 54 so that only the elongated section of the cylinder extends through the snuffer and the sparking wheel. The upper edge of the cylinder is in face-to-face relationship with the lower surface of the upper leg 48 and in cooperative alignment with an opening 55 extending therethrough. The diameter of the opening 55 is less than the diameter of the throughbore 56 of the cylinder. A screw 57 extends through the opening 55 into the throughbore 56 and is threadably mounted therein.

The screw 57 impinges on a coiled spring 58 which in turn is biased against a ball 59 constructed of steel or other material riding in the end of the throughbore 56 within the flanged lower section 52.

The diameter of the flange 52 is somewhat less than the cross-section of the guideway 43 and the top plate is so positioned that the flange rides within this guideway when the plate is rotated. In the closed position, the ball 55 is secured within the throughbore 56 between the spring 58 and the lower surface 60 of the guideway 43 as shown most clearly in FIG. 12. When the top plate is rotated to place the lighter mechanism in a position for lighting, flange 52 rides in the guideway 43 and the ball moves along the lower surface thereof until it reaches the indent 44 whereupon the action of the spring 58 causes the ball to move into the indent to lock the top plate in place. When force is applied on the top plate in the opposite direction, the ball is forced out of the indent and the flange and ball ride through the guideway until the top plate reaches the closed position for the lighter.

The burner valve 18 is of the conventional type including a fixed member 61 communicating with the fuel reservoir and a movable member 62 slidably mounted therein within the lower portion thereof positioned against a valve mechanism, including a resilient washer, so that when the movable member is in a depressed position no fuel escapes from the burner valve and when the movable member is in the raised position, fuel is emitted. An adjusting arm 47 is connected to the burner valve and controls the movement of the fixed and movable members so that predetermined amounts of fuel are delivered by the valve. In this invention the snuifer 17 is adapted to depress the movable member 62 to shut off the flow of fuel when the lighter is in the closed or inoperative position. The snuifer is mounted in the top plate so that when the same is rotated to the position for lighting, the movable member of the burner valve rises to the position of fuel emission.

An opening 63 is formed in the upper leg of the top plate and placed so that when the plate is rotated into the operative position, it is directly above the burner valve 18 as shown particularly in FIG. 13. It has been found that with this arrangement the flame is contained above the top plate so that no heat is generated within the area adjacent the burner valve. It is an important advantage of this invention that as a result of the flame being contained above the top plate, the body member and many of the parts therein can be constructed of nonheat resistant material such as plastic. This permits substantial savings to be realized in the manufacture of lighters within the scope of this invention.

The mode of operation of the lighters of this invention will now be described.

In the closed or inoperative position an edge of the flint is biased against the sparking wheel by the action of the spring 33. Only an edge rests against the sparking Wheel because the throughbore 25 carrying the flint is constructed at such an angle that the flint is forced into this relationship with the sparking wheel. The edge of the flint biased against the sparking wheel is off-center of the sparking wheel so that a tangential force component is applied thereto which is sufficient to lock the top plate in position to prevent accidental movement. It will be noted that in the closed position the snuffer keeps the movable member of the burner valve depressed so that no fuel can escape. There is thus provided a simple operating mechanism for safely preventing the escape of fuel from the burner without the use of the intricate snuifer means heretofore required. Instead of an expensive machined part, the snuffer is a simple spring leaf.

The sparking wheel, as shown, is accessible from the outside of the lighter when it is in the closed position. Application of hand pressure to the wheel in a direction parallel to its circumference opposes and overcomes the tangential force of the flint biased against the wheel and in one and the same motion rotates the top plate as guided by the guideway 43 until the ball 49 drops into the indent 44 locking the top plate in the open position. At the same time, the sparking wheel is moved to a position substantially perpendicular to the flint and the snuifer is disengaged from the movable member of the burner valve. Continued application of hand pressure will rotate the sparking wheel against the flint to produce sparks for ignition of the fuel. At the time when the top plate is locked into operative position, the opening 63 in the cover plate overlies the burner valve and, as aforesaid, the flame when produced is contained above the cover plate.

Return of the cover plate to the inoperative position extends through the snuffer and the sparking wheel.

is elfected by merely exerting suflicient pressure to overcome the force of the spring 58 holding the ball 59 in the indent 44. In the embodiment shown the top plate can be rotated until the sparking wheel strikes the projection 37, as shown particularly in FIG. 9, whereupon further rotation ceases. There are, of course, other possible positions for this stop, and other methods of stopping rotation.

The embodiment of the invention illustrated in FIG. 15 is similar to that illustrated in the other figures and similar parts of the separate embodiments will be identified by the same reference numeral with the addition of the subscript b. As illustrated, the embodiment of FIG. 15 comprises a lighter of this invention mounted in the upper barrel 12b of a pen b and includes a rotatable top plate mounting a sparking wheel 16b and a spring leaf snuffer 17b. A burner valve, generally represented by 18b, communicates with a fuel reservoir 19b. The burner valve mechanism is identical with the mechanism described in connection with the previously is U-shaped in configuration and the dimensions of the upper leg of the U 48b are such that it is equivalent to the top area of the lighter. The vertical leg of the U is not visible in the figure since it is behind the sparking wheel 16b but it extends downwardly from the upper leg. The lower leg 50b extends from the lower edge of the vertical leg to complete the U and the sparking wheel 16b and snulfer 17b are enclosed within the 'U.

A cylindrical member 51b having a flanged lower section 52b extends through an opening in the lower leg 50b in direct line with a cooperating opening in the spring leaf snuffer 17b, the same having a similar relationship with an opening 54b in the sparking wheel. The opening 54b is somewhat larger in diameter than the outside diameter of the cylinder member 51b. Hence the sparking wheel is rotatable about the cylinder. The

lower flange 52b is of larger diameter than the opening 54b so that only the elongated section of the cylinder The upper edge of the cylinder abuts the lower surface of the upper leg 48b and is in alignment with an opening 55b extending therethrough. The diameter of the openin-g 55b is less than the diameter of the cylinder 51b. A screw 57b extends through the opening 55b and is threadably mounted in a tapped hole 64 in the cylinder. When the screw is turned down, the various components of the top plate are secured in place.

In the previous embodiment, the cylinder 51b was completely hollow and mounted a coiled spring 58 biased against a ball 59 which rode in a guideway 43 on the upper surface 42 of the lower horizontal base 24. An indent 44 in the guideway served as a receiver for the ball when the lighter was in the operative position. In the instant embodiment the various parts are essentially reversed. Thus it will be seen that the spring 58b is mounted in the body member 21b and is biased against a ball 5% which in the open position of the lighter is received in an indent 65 in the lower surface 66 of the flange 52b. The flange rides in a guideway 67 on the upper surface 42b of the lower horizontal base 24b.

The operation of the lighter illustrated in FIG. is similar to the operation of the previously described lighter. In the closed or inoperative position the snnffer depresses the movable member of the burner valve so that no fuel escapes while the flint impinges tangentially against the flint wheel which is accessible from the outside of the lighter. Application of any force overcomes the tangential force so as to rotate the top plate 15b and move the flange 52b in the guideway 67 until the ball 5% is forced into the indent 65. At the same time, the sparking wheel is moved into operative relationship with the flint while the snulfer is disengaged from the burner valve.

In the open or operative position an opening in the top plate, not shown in the figure but similar to the opening 63 of the earlier described embodiment, overlies the burner valve. In this position continued application of hand pressure rotates the sparkling wheel against the flint to produce sparks and ignite the fuel. Again the fuel burns above the upper surface of the .top plate.

The other parts of the lighter shown in FIG. 15 are similar to corresponding parts illustrated in the earlier figures.

In FIG. 15 there is shown a decorative cap 68 which is afiixed to the top plate, for example, by an adhesive. It is, of course, not essential to the invention but eontributes to the overall appearance of the pen lighter.

FIGS. 16 and 17 illustrate still another embodiment of this invention which is similar to the previous embodiments especially that illustrated in FIG. 15 except that the snulfer and burner valve are slightly altered. In describing these lighter parts, which are similar to corresponding parts of the previous lighters, they will be identified by the same reference numeral with the addition of the subscript c. As illustrated, the lighter of FIGS. 16 and 17 includes a top plate 156 rotatably mounted in the vertical wall 230 of a body member 210, the same being aflixed to the upper barrel of a pen 10c. The sparking wheel 160 is rotatably mounted in the U-shaped top plate between the upper leg 48c and the lower leg 590 on a cylinder 510 which is held in place by a screw 57c and includes a lower flanged section 52c having an indent 650 on its lower surface 660. The flange 52c rides in the .guideway 67c when the top plate is rotated and when the lighter is in the operative position receives in the indent 65c a ball which is biased by a spring in the body member 210. The ball and spring are not shown in the figures but are similar to the corresponding parts illustrated in FIG. 15. As mentioned above, the essential difference between the lighter of the last two figures and the lighter of the previous figures is the burner valve and snuffer arrangement. In this embodiment the burner valve is topped by a reciprocal cap 68 which covers the exit orifice and prevents escape of the fuel when the lighter is in the closed inoperative position. Two tined fork 69 embraces the cap in groove 70. The fork is mounted in the top plate under the sparking wheel in a manner identical to the mounting of the previously described snuifers so that rotation of the top plate moves the fork in the groove. The ends of the tines are elevated above the plane of the fork in an elongated S-shape so that as the higher sections of the tines 71 move into the groove 70 during the operation of the lighter, the cap 68 is elevated to permit the escape of fuel for lighting by rotation of the sparking wheel against the flint 26c. When the top plate is moved back into inoperative position, the higher parts of the tines 71 are moved out of the groove 70 and the reciprocating cap 68 returns to the position in which the burner valve is closed.

It is apparent that the embodiment of FIGS. 16 and 17 operates similarly to the previously described lighters. In one motion the burner valve is opened, the sparking wheel is brought into operative alignment with the flint and the same is sparked to ignite the fuel. The movement of the ball urged by the spring into the indent 65c locks the lighter in the open operative position. Motion in the opposite direction overcomes the force locking the ball into the indent and moves the lighter into the closed or inoperative position where it is safely locked by the force of the flint biased tangentially against the sparking wheel.

All of the other parts not specifically mentioned in the description of the last described lighter embodying the concept of this invention are similar to corresponding parts in the previous descriptions.

It will be seen that What has been provided is a lighter which in the closed inoperative position is safe and readily transportable without danger of inadvertent sparking or escape of fuel. Moreover, the lighter of this invention may be lighted in one simple motion without the intricate and expensive interrelationship between snuffer, sparking wheel and finger piece heretofore required. Also, because of the unique construction of the lighter, the flame is so placed that it is not necessary to use heat resistant materials for every part of the lighter.

Many apparent variations are possible without departing from the spirit and scope of this invention. For example, in the drawings the guideway and the indent for receiving the ball have been shown on the upper surface of the lower horizontal base and the spring and ball have been mounted within the sparking wheel in the top plate. It is entirely within the skill of the art to reverse the position of these various parts and to put the guideway and indent in the lower leg of the top plate while placing the spring and ball in the body member. Similarly, positions of other parts, for example, the adjusting arm of the burner valve, may be changed. The direction and rotation of the top plate from inoperative to operative position may be the opposite of the direction shown in the drawings and explained above. Of course, the operating mechanism of this invention need not be included in a pen although this embodiment has been described for purposes of explanation.

After study of this specification, various other modifications of this invention will be apparent to those skilled in the art to which it pertains. Reference should accordingly be had to the appended claims in determining the scope of the invention.
