4 claims. 01.' isi-'1.1)

My invention relates to cigarettev lighters and particularly to pocket lighters of the pyrophoric A particular object of the invention is to provide a lighter formed of two sections which, when they are pulled apart cause operation of the lighting mechanism to ignite a wick. A special object of theinvention in a lighter of this type is to limit the relative sliding movement between the parts 1,0 so that when they are pulled apart a. certain distance no further motion is possible, This is an important feature inasmuch as where the parts are freely` separable they are likely to be pulled apart so rapidly, in imparting the motion necessary to cause the lighting mechanism to operate,

that any flame which is formed will be extiniuished by the motion of the lighter through the r. A further object of the invention is to provide a lighter vof' this type in which the sections, movenot biased in any Way either towards or from each other, and are freely slidable through a limited range with respect to each other except forl the elements which operate the lighting mechanism. Still a further feature of the invention resides in the fact that the lighting mechanism itself is utilized for resiliently holding the lighter in closed, inoperative position. o 0 yA further object of the invention is theproviv fuel chamber of the lighter -is filled at a point adjacent the wick, this point being, however, concealed and covered when the lighter Ais in closed position. This prevents the soiling of the clothes of the user by any fuel which might possibly leak out through the lling opening.'

Further objects and'advantages of the invention will appear more fully from the following description particularly when takenin conjunction with the accompanying drawing which forms a part thereof. In th'edrawlng: Fig. 1 is a side elevation showing a lighter acctziording to the invention in open operative posion.

Fig. 2 is a crossl section through the same in closed position. 'Y

Fig. 3 is a cross section on the-line 3-3 of Fig. 2.

'I'he lighter comprises two sections A and B. The lower section B or body ofthe lighter comprises a shell or framework 2 lwhich is open at the bottom and is closed by a cap or shell 4. The 5;, inside of the shell 2 thus forms a fuel chamber 6.

ment of which causes operation of the lighter, are

sion of a novel filling arrangement, in which the The shell 4 may be secured on the frame 2 by means of a screw 8. 'I'he frame2 has an upward extension I0 forming a part of the fuel chamber and holding in its top a tube I2 in which is arranged a wick I4. This wick is preferably formed of a rigid, porous material, such as meerschaum. The wick I4 thus extends into and receives fuel from the fuel chamber. 'Ihe frame 2 also includes at its other side an upward extension I6 which extends above the wick I4 and includes an upper continuous ring or frame section I8 forming the top of the frame l2. This leaves a space 20 between the ring I8 and the extension I0' to permit access of air to the wick and to allow the user to bring his cigarette up to the wickA to be lighted. There is also provided between the upward extension I6 and extension I0 and the member I8 a. vertical slot 22 the purpose of which will be explained below.

'I'he upper section A includes a cover or a shell 24 adaptedv to slide over the upper part of the 20 frame 2 until it engages the upper edge of the shell 4. The arrangement then presents the appearance of a closed casing. Inside of this shell 24 is mounted a snuffer tube 26 which, when the cover or shell 24 slides downwardly, covers the wick so as to extinguish the flame and prevent the evaporation of fuel from the wick.

There is also provided on the cover an inwardly extending tube 28. This tube is closed at its upper end by a screw threaded plug 30 and encloses a coil spring 32. 'I'he tube 28 acts both as a flint holding tube and as a support for 'the lighting mechanism. At the lower end of the tube 28 is arranged a frame work 34 which sup- 35 ports a shaft 36 on which is mounted a flint wheel 38 in engagement with a flint 40 arranged in the bottom of the tube 28. Likewise mounted on the shaft 86 is an operating pawl member 42 having a tongue 44 adapted to engage with ratchet 40 teeth 46 on the side face of the flint wheel 88. It is evident that when this member turns in one direction (counter-clockwise, Fig. 2) it will impart motion to the flint while upon turning in the other direction it will move freely with re- 45 spect thereto. A spring such as a coil spring 48 of the element 42. This tongue is so arranged' that upon upward movement of the shell 24 it' will engage the hook 54 and cause the element 42 to turn in a clockwise direction against the action of the spring d8. When the cover or shell 2li reaches a certain 4point inits travel, the inclination of the surface of the Yhook 5d will cause it to slide over and displace the end of the resilient.

member 5d, and then the member d2 will turn rapidly under the action of the spring 48,'thereby rotating'the int wheel to throw sparks on to the wick.

When the lighter is moving backward towards closed position the element 42 slides easily over the resilient member 5G' back to the position shown in Fig. 2.

' In order to limit relative sliding movement between the two sections of the lighter, I provide a pin 60 which is engaged andsecured in the opposed side walls of the shell 2li, and which passes through the slot 22. It is evident that this pin will limit the relative movement of the two parts of the lighter betweenv the positions shown in Fig. 1 and in Fig. 2.

In order to ll the lighter,I I provide a screw 62 arranged in the upward extension i@ of the frame, in an aperture which communicates with the fuel chamber at a point near the wick. This screw is so located that when the lighter is in closed position it is covered by the upper portion 2d. 4

If the cotton which lls the fuel chamber S is to beremoved for any reason, it is only necessary to take out the screw 8 and the shell may then be slid off the frame 2.

It will be noted that there is no mechanism biasing the lighter either to closed or open position, so that the motion is entirely controlled by the user. However, when the lighter is in the closed position as shown in Fig. 2, the lighting mechanism itself holds the lighter against accidental opening since such opening involves a compression of the spring $8.

While I have described herein one embodiment of my invention I wish it to be understood that I do not intend to limit myself thereby except within the scope of the appended claims.

I claim:

1. A cigarette lighter comprising two relatively slidable casing sections, one of said sections having a fuel chamber therein, a wick carried by said iirstsection and communicating with said fuel chamber in'such a position as to be exposed through the opening between .said sections when they are moved apart, means limiting the relative movement between said sections, ailint tube carried by the second section extending downwardly therefrom, a flint mounted in said tube, igniting means carried by the lower end of said tube including a flint wheel engaging said int, and means carried by said iirst section engaging said igniting means to operate the same whensaid second section is ,moved apart from said first section. 'J

2. A cigarette lighter comprising two rela.-

-tively slidable casing sections, one of said sections having a fuel 'chamber therein, a wick carried by said iirst section and communicating with said fuel chamber in such a position as to be exposed through the opening between said sections when they are moved apart, means limiting the relative movement between said sections comprising a slot inone and a pin secured in the other and extending through said slot, a flint tube carried by the second section extending downwardly therefrom, a iiint mounted in said tube, igniting means carried by the lower end of said tube including a flint wheel engaging said iiint, and means carried by said first section engaging said igniting means to operate the same when said second section is moved apart from said rst section.
