6 Claims.

The present invention relates to 'p'yrophoric lighters for use with a liquifled gas, and more particularly to pocket cigar lighters.

It is an object of the present invention to provide a pyrophoric lighter with a detachable gas tank which can be easily removed and exchanged.

It is another object of the present invention to provide a pyrophoric lighter in which the parts are locked when in operative position.

The invention comprises a detachable gas tank; a device mounted on said tank for releasing and igniting the gas; a sheath partially enclosing said tank; means mounted on said sheath for controlling said gas-releasing device; a casing arranged to envelop said sheath enclosing said tank and carrying said controlling means; and a detachable dint-holding device engaging said sheath and engaging said casing and forming a locking means for holding said sheath and said casing in position.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specic embodiments when read in connection with the accompanying drawings, in which:

Figure 1 is a vertical section of the lighter according to the invention.

Figure 2 is an end view of the lighter.

Figure 3 is a vertical section along line A-B of Figure l. Y

Figure 4 is an horizontal section of the lighter along line C-D of Figure 1.

Figure 5 is a vertical section along line E-F, of Figure 3.

Figure 6 is an horizontal section along line G--H of Figure 5.

As can be seen from these drawings, the cigar lighter comprises a case or outer envelope I, closed at its base by a removable bottom la (Fig. 2). Inside this case is housed the tank 2, comprising a closed envelope containing the liqueed compressed gas used as a fuel. On an inclined part of the roof of the tank 2, the gas releasing device 3 is arranged, through which the expanded gas escapes, and which, in the shown embodiment, also acts as a burner, the assembly of the tank and the gas releasing device forming a unit.

The tank unit 2, previous to its insertion in case I is engaged inside a sheath 4 which partially surrounds it and which, on its side edge, has a notch 4 allowing the easy disengagement of the tank unit.

A removable sheath 5 is provided between the movable bottom -I of the case and the sheath 4 containing the tank unit 2 in order to hold the sheath and the tank unit in position.

In the upper part of case I, above the sheath 4 of the tank, is arranged a small independent casing 6, wherein is housed the whole of the control mechanism for the gas releasing and igniting device 3. This mechanism comprises a small plate I bearing on the lower bottom of the casing 6 and including two ears 'Ia which serve as bearings for an axle 8 on which a lever 9 is mounted for rotation whose end terminates into a fork 9a arranged under the head of the releasing and igniting device 3 (Figure l). A spring I0, for instance a torsion spring, tends to pull downwards the end of the fork 9a of lever 9. On axle 8 are articulated the two downwards moving ears I Ia of a small plate I I, which presses against the upper part of case I and which is extended yby a lever I2 whereon is attached a push control I3 extending outwardly through an aperture Ib of the case. In the upper part of the case, next to the casing G, is housed a second small casing I4 (see Figures 3, 5 and 6), wherein is engaged the stem I5 of the flint holding device, extended by yoke I6, whose axle carries the ignition wheel I'I for acting on the ferrocerium flint IB and its control wheel I8. A lining I!)8L closes, at its base, the casing I4, so as to leave in the latter an aperture of a particular shape which allows the replacing of the flint holding device in a correct position in its housing.

An aperture Ic, provided in the upper part of the case (Figures 1 and 2) above the burner 3'* of the gas releasing device 3, allows the exit of the flame from said burner.

The two small upper casings 6 and I4 are formed by an S-shaped plate which is attached to the upper part of sheath 4, so as to allow their removal from the case, together with the sheath and tank. Once the sheath is in position inside the case, the flint holding device engaged in casing I4 constitutes a lock which prevents any undue exit of the sheath together with the tank and the control mechanism for the gas releasing device.

The operation of the cigar lighter so designed is effected very simply by depressing the push control I3, which, through the action of the forked lever 9-9, causes the opening of the gas releasing device 3, and, consequently, the

exit of the gas. By acting at the same time on The replacement of the ferro-cerium int, after it has been worn out, is effected very simply by withdrawing the iiint holding device from casing Il. 'Ihe replacement of the gas tank 2 is effected by removing the lower bottom I'I of. case l and by withdrawing the sheath 4 together with the tank 2 which it partially clamps, after having, ofcourse, previously withdrawn the ilint holding device to unlock the sheath. 'I'he tank is easily removed from the sheath by pushing it through the side notch l* o the latter.

The tank used with this cigar lighter is preferably a tank containing an inner absorbent support for producing a rst expansion of the gas of the kind described in our copending U. S. application No. 757,314 iiled on June 26, 1947. The releasing device carried by this tank is preferably of the type described in our copending application U. S. No. 646,540, filed on February 9, 1946.
