driven bythe lighter capand is rotated through a' wide arc to produce an efficient spark, and in which the number of operating partsis reduced to aminimum;

Other objects and advantages of myiinventi'on will appear from the following description of apreferred embodiment and from the drawings, in Which:

open bottom of the body cap l3 pivotally affixed to the body by pin The top of the lighter cap is gently rounded to be engaged by a thumb orlother finger of a hand and to be actuated thereby. The cap extends down over the body of the lighter in frontand curves upward at the rear..

As shown in-Fig. 3; the bodyportion ll consists of anouter wall [5, a base plate It afiixedto theinside of said wall near the upper portion of the body and which dividesthebody portion into an upper section30 and a lower section 3|. The upper section 30 is of a generally rectangular cross-sectional shape. The base plate is provided with an aperture forthe wick l1 and with a threaded flint tube "3* which projects therethrough and which contains the flint 19, the flint spring and the adjusting. screw 2 l. The lower section 3| is filled with an absorbent mass 22'to absorb and hold the lighter fluid. The closure 12 which fits snugly into the body conceals the absorbent mass and the flint tube, prevents the lighter fluid from evaporating and provides the means by which the wick maybe replaced, the

from a comparison of- Figs. :1v and 2, the external parts of the lighter comprise. a body portion 1 l, a closure [2 which nestsin the:

flint-replaced or adjusted'and the fluid supply replenished. 1

As shown in Figs. 3 and 4, the outer wall l5 of the upper section is formed so as to provide a high upstanding rear portion by which the pin I4' and the cap l3 are supported and which continues around both sides of the upper section so as to provide a wind deflector for the sparking means and the wick. Directly before the wick at the front of the lighter, the wan is cut down to provide an entrance for-thecigar or cigarette-end when the cap is lifted. r 1

As can best be seen 'by a comparison of Figs; 3

. and 5, pin 14 projects through both sides of the outer wall lit at the rear of the lighter and through both sides-of the cap l3; the protruding ends of the'pin are spread. Thus, the cap is rotatably afiixed to the lighterbody, and as can be seen from a comparison of Fig. 2,- showing thecap inthe closed position and Fig. 4 showing the cap in the open-position; due-to the shape of the cap and the oif centerposition of pin l4,-'the cap is capable of rotating-some to from.

theclosed to th'efully openposition when the outside rear wall of the cap contacts the rear wall of the upper section.

As can best be seen in Fig, 6, a platen is affixed to the inside of the front of the cap I3 The V plate 23 is provided with an aperture 24, through which the pin I4 fits when the lighter is assembled. Plate 23 isprovided with an extended portion 25 having a cam ZQwhichis adapted to engage the sparking wheel; r v As shown in Fig. 5, rotatably mounted on the center portion of pin l4 between the walls" l5of the. uppersection 30 is plate2'3, sparking wheel 26, and coiled spring 21; "Coiled spring-*2! is tightly wound' so that the-coils -contact each other; The left side'of wheel'2fi is provided-with four wedge shaped elements 28, radiallyd'isposed at equal angular" intervlals thereon. Plate 23 rests-against the shaped side of wheel 28 and cam 29 isin position-to engag one of the'ele- 2 I. Spring -21-"is""'co'iled arduridfliirfI4 and one end of the spring presses against the inside of the front wall of the cap and the other end on pin 14 in the directionof thearrow. As prethe roughened surface "by s'prin p211. and screw;

. a I i 3 viously explained cap I3 is positioned to rotate some 100 to 110, but sparking wheel 26 has only four wedge-shaped elements on it and thus can be rotated only approximately 90. Thus the movement of the cap which causes plate 23 to rotate on pin I 4 moving cam 29 toward the wadge-shaped element of wheel 26 encompasses some 10 to 20 of rotation before the cam contacts the; wedge, element. In this interval of movement coiled spring-21 is beingwound, which causes its tightly coiled width to expand between the walls of the upper section and the flat side of wheel 26 and forces the shaped side of the wheel 26 against plate 23, so that when the cam contacts the wedge-shapedel'ementoi the wheel, to cause the wheel to rotate; there-is aapositive pressure between the wheel and the plate which insures that the cam will engage, the-wheel, and positively rotate it. This pressure increases as the wheel is rotated.

Thus as cam 29 rotates wheel 26, the wheel strikes a shower or spar-ks; from flint; l; directed against wick l1. V
