This invention reietestc lighters and has for an object to provide a construction wherein the lighting elements will be caused to quickly function without any predetermined effort on the part 5 ofthe operator.

Another object of the invention is to provide an improved lighter wherein the parts are moved at any desired speed to a given position and then a resistance presented so that an extra. pressure will quickly -move the' parts to a completed position and thereby give the serrated wheel of the device a sudden quick movement. A further object of the invention is to-provide Van improved construction which will quickly and automatically ignite a wick when actuated and quickly put out or snuff the wick when released.

In the accompanying drawing- Fig. 1 is a longitudinal vertical sectional view through a lighterembodying theinvention, certain parts being shown in elevation:

Fig. 2 is a sectional view through Fig. 1 approximately on the line 2-2; Fig. 3 is a sectional view through Fig. 2 approximately on the line 2-3 but showing only 3,5 a portion of the device illustrated in Fig. 1;

Fig.' 4 is a transverse sectional view through Fig'. 1 approximately on the line l-I;

Fig. 5 is a `fragmentary sectional view 'through i Fig. 1 approximately on the line 5 4:

80 Fig. 6 is a fragmentary transverse sectional view through Fig. l'on the line 6 6;

Fig. 'I is a perspective view on a reduced scale of the housing or casing shown in Fig. 1.

Referring to the accompanyins drawing by 85 numerals, i indicates a housing or casing which is bent or stamped from sheet metal. f The respective edges 2 and l are held together by rivets 4 and 5 which also act to perform other functions as heretofore fully described. The casing I is provided with suitable air vents O so as to provide the proper amount of air to support combustion when the wick 1 is ignited. The wick 1 extends from the usual fluid container I and is correctly positioned to receive the spark when the device is a5 functioning. Y

- In regard to the rivet 5 it acts as a Journal pin` for a swinging cap 9. This cap functions also to actuate the serrated wheel ill and the snuifer il which is rigidly secured thereto in position to fit over the wick 1 when the device is not functioning, as clearly shown in Fig. 1. The serrated wheel i0 is rotatably mounted on the rivet or pin B and is provided with the usual abutments i2 which are adapted to be engaged by respective resilient arms I3 and Il so asto rotate the wheel when these arms are moved inone direction. It will be observed that these arms are an integral part of the plate il which is `iournaled on the pin or rivet l and is provided with extensions it and i1 bearing against the cap lso that the plate and g arms will move with the cap. When the arms are moved clockwise as shown in Fig. l they will also move the wheel il. but when moved counterclockwise the arms will resiliently pass over the abutments i2. l

Associated with the serrated wheel il is a flint Il which is slidably mounted in a tubular collar il and pressed by a spring 20 so as always to properly engage the serrated wheel I0. A knob ai is secured te the cap s and is adapted vtc be is.;

pressed in a direction to the right, as shown in.

Figs. l and 3, wheny it is desired to ignite the wick "-1 `1.-. The slow movement. of the yparts causes the wheel i8 to rub against the flint il but usually will not provide a suilicient spark to ignite -the n wick 1. i It is desirable to swing the cap to a partially open position and then to quickly rotate ythe wheel il to give a large spark sc that the wick 'l will be ignited on each operation. To result a special construction has been provid It will be observed that an elongated abutment 22 is secured to the side member .23 ofthe end of cap s, while a pin 2l isA connected to the opposite. side member 2B. Preferably the cap is made froma single piece ofpressed metaihavlo ing a back, twosides and an end. The two sides adjacent the knob 2i are rounded-.to form the members and 2L A lever '2l is pivotaliy mounted on pini l. as shown in Fig. 1. and is continually pressed by` a spring 21 which acts g5 against a shoulder 2l and against a wall of housing 2l so as torcause thelever 2l a continuous tendency to move to the right, as shown in Fig. l, to continually press against theabutment 22. Therefore. when the abutment 22 has been movedover to the left, asy shown in dotted lines in Fig. l, and then released the lever 2l will quickly move the. parts back to `the position shown in Fig. l. However, when the knob 2i is pressed clockwise. as shown in Figs. 1 and 2, t hel u pin 24 connected to theside plate `2lwil1 engage a spring pressedswinging abutment 30st the point or shoulder-'3l and force the same to the leit. as shown in Fig. 1. The abutment 30 is pivotally mounted at 32 onthe arm 33 of a bell 50 crank lever 34, which' lever is pivotally mounted on pin I4' carried by housing 29. The opposite arm 35 of the bell crank lever is pressed by a spring 36 so as to remain normally in the position shown in Fig. l. A spring l1 is connected u at 38 to the bell crank lever 34 and at Il to a small extension from the abutment Il. The spring 31 attempts to keep the abutment ll pressing against the point or shoulder 40 of the bell crank lever 34. When the knob 2| is moved clockwise, the pin 24 strikes the shoulder 43l and this shoulder, acting through the bell crank lever and spring just described, will resist further movement. However, if a harder push is given to the knob 2|, spring 36 will quickly move and the abutment 30 will move out of the way of pin 24 so that the parts will give the wheel Il a quick partial movement and thereby produce a good spark. This spark occurs after the snuilerl Il has been moved oil the wick 1. After the knob 2| lhas been moved to the right as far as possible, as shown in Fig.` 1, it together with the cap 9 and associated parts will move under theaction of arms or levers 2l, back to theposition shown in Fig. 1 ready for a second operation. Abutment 30 and bell crank lever 34 will also quickly move back to their former positions under the action of their respective springs. When the pin 24 moves backward the abutment 3l swings away from the point or abutment 4I and allows'pin 24 to pass, after which it resumes the position shown in Fig. Just described.

It will be seen, therefore, thatthe first movement of knob 2| and cap l will merely uncover the wick 1 and the second quick movement will produce the spark. The abutment 22 during the iirst movement will move the upper end of lever 2t and during this time the snuii'er Il has been elevated until the vwick 1 is completely free so that as the lever 28, pin 24 and associated parts move over to their extreme positions `the wick will be exposed ready to be ignited.

In regard to the abutment 22, it lwill be seenl that the same is elongated with half-round ends4 land connecting nat sides. As shown in Fig. 1, the major axis is arranged substantiallyradial' ing a casing, a fluid container having a-wick, il.`
