FREDERICK ALEXANDER ALLEN EVANS, OF LONDON. ENGLAND,

VAPOR-LIGHTER.

To all whom it may concern Be it known that T, F REDERICK ALEXANDER ALLEN EvANs, a subject of the King of Great Britain. residing in London, England, have invented certain new and useful Improvements in Vapor-Lighters, of which the following is a specification.

In an appliance, herein called a vapor lighter, for producing a flame by causing sparks generated by friction to impinge on a wick saturated with petrol or like fuel, ignition in a current of air is more certain and the flame less liable to extinction, when the sparks are generated within a chamber which also contains the wick and is closed save for the opening through which access is had to the flame.

This chamber should be separate from that containing the fuel and for this purpose the chamber has been formed by a diaphragm which is either a transverse parti tion in the tube constituting the body of the lighter, or the closed end of a second tube slid into the body tube; in each case the material saturated with petrol is on one side of the diaphragm through which the wick extends.

It is to this particular form of vapor lighter having the spark generator and wick within a chamber formed by a diaphragm that the present invention relates.

Hitherto the ignition in this form has been by means of relative sliding movement between the scraper and the so-called flint, the inner tube being slid into the outer tube to produce the sparks.

By the present invention the well known friction wheel turning on a pin is adapted as the scraper by mounting the pin in the plate that closes the body tube or in lugs on the side of this tube, the wheel turning in aslot so that it extends into the tube to abrade the flint mounted therein.

I have shown in the accompanying drawings Figures 1 and 2 axial sections of two vapor lighters each having an ignition chamber formed by a diaphragm and a wheel scraper mounted in accordance with the invention.

Referring to Fig. 1, the vapor lighter comprises an inner tube a fitting closely in an outer tube 5, so as to turn therein. The outer end of the innertube has a milled head 0 by which it can be readily turned to bring into register with each other the lateral opening d in each tube, this being the po Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed August 12, 1919. Serial No. 317,052.

sition shown in Fig. 1. By turning the tube a through a suitable angle, say one of 90, the opening in the inner tube becomes wholly out of register with that in the outer tube and the chamber 6, formed in the outer end of the inner tube by the diaphragm f, is closed. The part of the tube a on the other side of this diaphragm is packed with absorbent material f/ and the wick tube It extends'through the diaphragm, the wick being embedded at its inner end in the absorbent material.

According to this invention the friction Wheel 11 is mounted to turn on a pin carried in the head 0 and its milled periphery bears aga nst the usual flint. 70 mounted within the tube a and urged against the wheel by a spring Z adjustable by a screw m, in the known manner.

Normally the relative angular position of the tubes (1 and Z) is that in which the openings cl are closed. For use the inner tube is turned into the position shown, the movement being governed by one end of a notch a at the bottom of tube a, engaging with a stop 7) on the tube 6. The wheel is then rotated by the finger, as usual, whereby sparks are generated and ignite the wick. To saturate the absorbent material, tube a may be withdrawn from tube 6 and its open end immersed in petrol.

In Fig. 2 the absorbent material is contained in a tube a closed at both ends and pushed into the outer tube Z), the wick tube 72. extending through the inner end of this tube o The chamber 6 is formed in the outer tube 6 between the closed end of tube a and the hinged lid n. The friction wheel 2' turns on a pin carried by lugs on the outer tube 6 and the flint is extends through the end of a recess 0 in the outer tube; it is subject to the pressure of spring Z, adjustable by turning screw 712. To saturate the absorbent material the tube a is withdrawn and immersed in petrol which enters the tube through an aperture 72.

Having thus described the nature of the said invention and the best means I know of carrying the same into practical effect, I claim 1. A vapor lighter comprising a tube, a diaphragm in the said tube subdividing it into a wick chamber and a fuel chamber, a wall of the Wick chamber having a slot, a friction wheel mounted for rotation in said slot, and a fiint contained within the said Wick chamber, the said flint and wheel being in operative contact with each other Within the Wick chamber.

2. A vapor lighter comprising an inner tube, a diaphragm in the said tube subdividing it into a wick chamber and a fuel chamber, an outer tube closed at one end into which the inner tube fits so as to turn therein, said inner tube having a milled head 10 and a pin traversing the said slot. a friction wheel mountedto turn on the said pin as in axis and having a diametrical cross sec- :1011 of SllbSHlIlUliiY the same area as the ength or the slot. and a flint mounted in the said wick chamber in operative contact ith the friction Wheel.

In BBSEllIlOIlV whereof I have signed my name to this specification.

REDERICK ALEXANDER ALLEN EVANS.
