' A. CORPORATION OF NEW JERSEY LIGHTER CONSTRUCTION Application led November 17, 1928. Serial No. 320,042.

This invention relates to lighters and` has l i particular reference to the type of lighter in which a sparking unit is manually operated to throw sparks on a wick moistened by an inflammable liquid.

The particular example of the inventio here shown includes a suitable pyrophoric means cooperating with a rotatable abrasive or sparking wheel, the latter being in turn actuated by the depression of a manually operated plunger so as to cause sparks tobe thrown on to an adjacent wick. In this example a snuffer is also provided for the wick and operatively connected to be controlled by the manually operated plunger.

The objects of this invention include the provision of an exceptionally 'efficient and dependable operating mechanism for controlling the movement of the abrasive wheel and snulfer, and also the provision of a convenient4 wick adjusting means, all embodiedin a comy pact and relativelyvsimple device of good A tion, and illustrate preferred embodiments of the invention, and in which,

The example of the invention show n 1n Figs. 1 to 8 inclusive, comprises a relatively tall thin casing 20 forming a chamber within which is contained a suitable fuel to be drawn up througha wick 21. A wick sleeve 22 1s fastened to the top plate 23 of the caslng 20. When the device is not in use the sleeveat the top is engaged by a snubber means including a rubber sleeve 24 disposed within a metalllc sleeve 25 dependent from a snufer carrying member 26. This member comprises a top wall 27 and side walls 28 and 29, and extends rearwardly from the snuffer sleeve 25 for forming a housing for a sparker wheel 30 mounted on top of the lighter. The snufer member and the sparker wheel are mounted on a shaft 31 journalled at its ends in spaced supporting lugs or plates 32 and 33 projecting upwardly from Vthe top plate 23 of the casing 20. Fas'tened to the outer sides of the walls 28 and 29 and concentric with the shaft 31 are pinions 34 and 35 rotatable with the snuferearrying member. These pinions are engaged by rack teeth on wing-arms 36 and- 37 connected to and operated by a plunger shaft 38 having a finger piece or head 39. The plunger 38 extends downwardly into a 100 tube 40 within the casing 20 and beneath it is a spring 41 tending to force it out of the tube. This spring, therefore, it will be observed, will normally keep the parts in the position shown in Fig. 2. When the plunger is depressed, the rack teeth on the arms 36 and 37 will turn the pinions 34 and 35 and with them the snulfer carrying member 26 thus uncovering the wick 21.

Between the side walls 28 and- 29 of the i member 26 and loosely mounted around the shaft 31 are ratchet pinions 42 and 43 on op-` posite sides of the sparking wheel 30. The ratchet 42 has a hub 44 extending axiall therefrom and on the outer end of whic ratchet 43 rotates. rThe ratchet 43 has a hub 45 extending axially therefrom around the hub 44. The sparking wheel 30 is bored io receive the hub 44 and along its closed side 46 is fastened to ratchet 42 by means of a pin 47 which projects into the hollow interior of the wheel 30. On its inner end this pin 47 engages the end of a coiled spring 48 which is wrapped around the hub 45 and the other end of which is connected to a pin 49 fastened -to the ratchet 43. The teeth of the ratchet 42 are normally engaged by a pawl 50 pivoted at one end to a lug on the top plate 23 of the casing 20 and held in engagement with these teeth by means of a spring 51 housed in a tube 52. A short pin 53 on the wing arm 36 is in position to engage with the pawl 50 when the plunger 38 is depressed nearly to its lowermost position so as to force the pawl out of engagement with the teeth .of the ratchet 42.

Beneath the top wall 27 of the snufer carrying member is disposed a short stub shaft 53a around which is coiled a spring 54, one end of which bears against the inner face of the wall and the other end of which bears against 'a pawl 55 pivoted on the shaft 53a and having an end engaging the teeth of the ratchet 43.. The ratchet 43 closes the opening within the sparking wheel 30. This ratchet is permitted to turn to a limited extent independently of the wheel 30.- When the plunger 38 is depressed by the operator, the snuffer member is elevated and as this movement starts, the'pawl 55 is raised and turns the ratchet`43. This causesthe spring 48 to be wound up since the other end of it is engaged by the pin 47 connected to the ratchet 42 which is then being held stationary by the pawl 50. When the plunger reaches nearly or substantially its lowermost position and the snuer member has been elevated to a position remote from the wick, as shown in Fig. 8, then the short pin 53 on the wing arm 36 will engage the pawl 50 and remove it from engagement with the teeth of the ratchet 42. This release of the ratchet 42 which is connected to the sparking wheel 30 will permit the wound up spring 48 to snap the sparking wheel around and produce sparks by 'contact with a suitable pyrophoric element at 56. This element projects from the upper end of a tube 57 extending through the casing 2() to the bottom thereof and 1s backed by a spring 58. The lower end of the spring 58 is held in position by a closure cap 59 threaded into the lower end of the tube 57. The angle of engagement of the pyrophoric element and the sparking wheel 30 is such as to throw sparks in the direction of the wick 21.

With the sparking wheel operated as above described, the sparking effect may be intensely concentrated within a very short space of time, during which the sparking wheel is caused to move much more rapidly than would be generally feasible with directvmanual pressure even when applied through gearing. Accordingly the eiiiciency of the pyrophoric means is not only enhanced as a result of the concentration of the sparking within a limited time, but the intensity of the spark-1 ing may also be substantially increased due to the increased speed of movement of the sparking wheel made possible by the sna action thereof. By this operation the snu er member may be removed from the neighborhood of the wick before the wick is ignited and therefore the snuifer member and particularly the rubber sleeve 24 is safeguarded against damage by burning.

In the modification shown in Figs. 9 to 13 inclusive, most of the parts are numbered for clearness, with the same numerals as usedI with corresponding parts as above described, since they are constructionally related in the same general manner, and need not be further described. However, in this example of the invention the spring 48 between the pins 47 and 49 is not wound around the hub 45 but is stretched circumferentially around the hub as appears in Fig. 12. The walls of the casing 20 are extended upwardly around the wick 21 on three sides thereof to form a windshield 60 therefor. This windshield also extends around the sparking wheel.

' The top of this shield is normally closed by the top wall 27 of the snuifer carrying member which lies Hush with the top of the windshield. Also the top or finger piece 39 of the plunger v38 in this example is so shaped that when in its upper position, it will lie substantially in the same plane as the top of the windshield and the top of the snuler as shown in Fig. 9. The top 23 of the casing is depressed as at 61 to permit the sparking wheel to be journalled closely adiacent the reservoir asv for compactness. The linger piece 39 is also provided with dependent end and side walls 62, 63 and '64, so that when `the parts are in their normal positions, the entire top of the lighter will be substantially closed and flat. y

'- The entire lighter construction may therefore be provided with an exterior contour,

substantially continuous except for the right angular corners. Such construction not only makes possible an enhanced appearance, but also ellminates the use of any protruding parts which might interfere with the proper operation of the device in the hand of the user or bring about accidental operation with its attendant dangers. v

In the modification shown in Figs. 11i to 16 inclusive, the wick 21 is engaged bythe teeth of a small spur gear 65 mounted on a strap 66 extending around the top of the wick tube 22. The tube 22 has a slot 67 therein to -permit theteeth of the spur gear to pass through. The gear 65 is rotatably mountedv on a sleeve 68 secured in openings in the adjacent ends of the strap 66, as shown in Fig. 16. This spur gear may be easily turned by engagement with ones finger and thereby the elevation of the wick may be accurately adjusted to insure efficient ignition. In this form also the snuler member is provided with dependent end and sidewalls 69, and 71 which, when the snutler is in its closed position as shown in Fig. 14, will entirely cover the top ofthe casing around the wick 21 and form a housing therefor as well as for the spur gear and associated parts.

The bottom edges of these dependent snuffer walls rest on the top 23 of the casing 20. The housing has a rear wall 72 which closes the fourth side thereof and separates the housing from the sparking wheel enclosure. This rear wall has a slot 7 3 in its lower portionto receive the top of the tube 57 as shown in Figs. 14 and .15. This wick control device may of course be used on other types of ligh ers than those shown in the drawings. f

Constructions may thus be provided-in which the snuffer element is removed from lthe` region of the wick before the sparking takes place which ignites the wick and therefore the snulfer and its associated parts are not damaged by repeated subjection to the heat of the flame; also, the snap action given to the sparking Wheel by the associated spring is effective to produce highly eiiicient sparking.

modifications avoids the use of projecting portions which tend to wear or tear the linv The smooth exterior presented in one fofth'e' example thereof which gives satisfactory results, it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.
