INVENTOR. CARL J. SIGEL COMM 2 (0% ATTORNEYS United States Patent 2,741,903 LIGHTER Carl J. Sigel, Akron, Ohio Application December 10, 1954, Serial No. 474,467

3 Claims. (Cl. 67-7.1)

This invention relates to lighters of the type in which a wick saturated with an inflammable liquid is ignited by a spark generated by rotation of a rotary wheel having a milled edge in contact with a body of flint or other spark producing material, and is especially useful as a pocket lighter.

While many pocket lighters have been proposed, such lighters as have been placed on the market have had certain faults in that either the inflammable material was subject to evaporation prior to striking of the spark, or the flame blows out in the wind, or the spark striking action is too slow to insure a good shower of sparks.

It is the object of the present invention to avoid the foregoing and other diflic'ulties by providing a quickacting spark mechanism, by avoiding exposure of the wick for a long period prior to generation of sparks, and to protect the flame adequately from sparks.

Fig. 2 is a sectional view thereof, taken on line 2-2 of Fig. 1;

walls thereof to contain a supply of inflammable liquid.

A tubular wick support 17 extends through the partition for supporting a wick 18. A closure plug 19 fills a V threaded opening 20 leading to the space 16 for filling it.

The inner case has a pair of oppositely aligned openings 21, 22, one at each side of the wick support 17. The outer case'has a pair of aligned openings 23, 24 normally offset above the openings 21, 22 respectively but adapted to be aligned therewith. to provide an open passage at the wick at the ignition period. The inner and outer cases are normally held inthe position illustrated in Figs. 1 to 3 by aleaf spring 25 mounted between them and are slidable one on the other by compression of the spring to align openings 21, 23 and 22, 24. n

For igniting the flame at the wick support 17, a shaft 26 is mounted for rotation horizontally of the inner case in bearings provided in its walls. Aflint striking wheel '27, having a milled edge, is mounted for free rotation about the shaft and is aligned with a flint guiding tube 28 received in the topwall ofv the inner case. A flint 29 is guided by the tube and is pressed against the wheel by a coil spring 30 and tension screw 31.

2,741 ,903 I I Patented Apr. 17, 1 956 ice For rotating the wheel 27, a pinion 32 is fixed to shaft 26 as is also a disc;33 (see Fig. 2). A ratchet wheel 34 is fixed to Wheel 27. A pawl35, for engaging the ratchet wheel, is pivotally mounted on disc 33 and is pressed into engagement therewith by a spring 36. A spring washer 37 is mounted about shaft 26 between the disc 33 and the wall of the case to act as a drag.

According to the invention, it is desirable to provide for striking a spark only after the inner and outer cases have been pressed toward each other and the openings 23, 24 aligned with openings 21, 22. It is also proposed that the spark striking action be accomplished with a snap action. To accomplish this a snap bolt 40, of U- shaped cross section is mounted in the inner case for vertical sliding movement. It has rack teeth 41 formed on one flange thereof for engaging the pinion 32 so that vertical movement thereof downward or toward the bottom of the inner case rotates pinion 32 and shaft 26 but does not rotate wheel 27 because of the ratchet connection. On reverse movement of the snap bolt, the rack rotates the wheel 27. The snap bolt is urged upwardly by a compression coil spring 42 mounted between a shoulder lug 43 on the snap bolt and the bottom wall 13 of the inner case.

For controlling operationof the snap bolt 40, the bolt is formed with a yertical slot therethrough 44 open at its upper end and a second vertical slot 45 closed at both ends. A flat spring 46 of L-shape is mounted within the channel of the snap bOlfWithj its long arm covering the slot .44 andriveted to' the snap bolt at the lowerend of the arm below the end of the slot 44 and with the short These and other objects will appear from the following description and the accompanying drawings.

arm of the spring extending across the slot 45 and flush with the upper 'end 'of thesnap bolt. The spring nor: mally lays flat against the floor of the channel of the snap bolt. i

Ai clearance slot 47 is'provided through the wall of. the inner case to expose the slot 44. A driving tooth 48 secured to the outer case 11 has a flat lower face and an inclined upper face. In the closed position of the case illustrated, the tooth 48 extends over the slots 44 and 47 which clear it with its flat lower face resting upon the upper edge of the spring 46. A cam lug 49 has an inclined upper face which extends inwardly of the case in the path of the horizontal arm of the spring 46. The arrangement is such that as the outer and inner cases are pressed toward each other the tooth 48 moves the snap bolt downward compressing the coil spring 42. As the cases reach a position where their openings 21, 22, 23 and 24 are aligned, the inclined upper face of the cam lug 49 flexes the horizontal arm of spring 46 inwardly beyond the driving tooth 48. This releases the snap bolt 40 which is then snapped upwardly, rotating the pinion 32 and the flint striking wheel 27 to provide a shower of sparks.

Upon release of pressure of the hand between the inner and outer cases, the upper inclined face of the driving tooth 4S deflects the spring 46 to pass above the horizontal short arm therof and the spring returns to a position blow the flat lower face of the tooth ready for the succeeding operation of the lighter.

In operating the lighter the inner and outer cases thereof are merely pressed toward each other until the side openings expose the wick at which point the snap bolt is released as heretofore described, lighting the wick. The case may then be held in this position until the operator has lit his cigarette, cigar orpipe. The case shields the flame from thewind and the cigarette, cigar or pipe may be held opposite the openings and the flame drawn outwardly of one of the openings by suction of the operator onthe cigarette, cigar or pipe. Upon obtaining alight, release of pressure on the case closes it and resets the mechanism.

Variations may be made without departing from the scope of the invention as it is defined in the following claims.
