Specification of Letters Patent. Patented Sept.V 20, 1910.

Application led December 15, 1909. Serial No. 538,172.

' To all whom' 'it 'may concern:

Be it known that I, LDWIG SCHN, a'citizen of the Empire of Austria-Hungary, re-

siding at Vienna, in the Empire of Austria- Hungary, have invented certain new and useful Improvements in Pocket-I iters, of which the following is a speciicatlon, reference being had therein to the laccompanying Y drawin This invention relates to a pocket llgnlter of that 'class which combines with a wick saturated with a combustible liquid ani niting mechanism, one of the objects of this invention being to eliminate phosphorus or other flame producing chemical agents and the cumbersome mechanism required for combusting such a ents.

Another object o this invention is to pro-` vide in a pocketigniter, a simple mechanism for producing a spark by frictional abrasion, thereby avoiding the dangers incident to that class of substances Which` produce Haine either by friction or detonation.

With these and other objects in View, this invention consists of the features, details of construction and combinationy of parts de- 4 scribed *in connection with the accompanying drawing and then more pointed out in the claims.

In the drawing, Figure 1, is a sectional particularly side elevation of an ignlterjembodying the invention. Fig. 2, is a sectional' elevation on lines A-B Fig. 1. Fi 3,'is a transverse section on lines C-DFigpl, and Fig. 4, is a side elevation of the ign1ter.

Reference being hady to the drawing,y a designates a casing having a hinged cover b, adapted tobe forced open by a spring f, and kept closed-by a snap 1', operable from the outside of the casing by a knob y, which.

extends through the casing. A' pin 71., fixed between the sides of the casing a, hasloosely mounted thereon a small toothed Wheel m, to which a ratchet wheel a, is rigidl secured. A paWl-lever d, having ivotall);T secured thereto a spring-actuate pawl e, is

also mounted on said pin lz., and is connected with the cover b, by a link p. The said toothed wheel m, its ratchet wheel n, and the pawl-lever d, are loosely mounted on y said pivot pink. When the cover b, is forced open under the tension of the spring f, the

pawl c, on the p'awl Alever d, engages the teeth of the ratchet wheel n, and rotates the same together with the toothed wheel m, in

the direction of the arrow Z. When, however, the cover is closed, the pawl c, glides over the teeth of the ratchet wheel n, without causing it or the toothed Wheel m to rotate, said latter wheel being held against rotation by the pyrophorous alloy, as will appear more fully hereinafter.

Part of the front side of the casing a, is

cutaway andthe bottom is wholly removed in order to admit of the insertion' of a liquid hydrocarbon lamp lv, into the casing a from` below. The edges of the cut-away portion orous alloy u, which is in constant engagev ment with said toothed wheel m, such engagement with the periphery of said ltoothed wheel being insured by one `end of a bell-crank lever 7c, which is pivoted in the sides of said casing a, while the other end of said lever c, is under the tension of a' helical s ring z', which is connected therewith. T e other end of said helical sprin z', is connected with a screw bolt t, whic passes through a hole provided in one of the projectin fiaps z, of the lamp fv. Engaging the-t readed shank of .saidfscrew bolt is .a nut w, by the manipulation of which the tension of the spring z', and the force with which the iece u, of the pyrophorous alloy is presse a ainst said toothed Wheel m, maybe contro ed. Said nut lw,

also serves to hold the lainp o, in its position in the casing. 4

Liquid hydrocarbon is supplied to the lamplv, through the orifice in the bottom thereof, which orifice is closed by a screw plul 0. l Tiie operation of the igniter is substantially as follows z-The push knob y, being 4pressed inwardlybythe thumb or other member, releases thefcoviemb, which then flies open under the tension of the spring f, causing thereby, through. its connections a rotation of the small wh el m, in the direction of the arrow. The abrasion of the ios ' transmitted in the'direction of rotation of and pawl adapted vto vthe said wheel and of the Wick j,

-of pyrophorous allo -mounted therein,

of the lamp o, which Wick 4is thereby ignited. The said wheel m, is provided with teeth primarily to effect a continuous roduction' of sparks during its rotation against the pyrophorous alloy, which would not be possible were the periphery thereof smooth.

`The closing of the cover b, places the elements c, d, and p in operative position.

When it is desired to remove the hydrocarbon lamp fv, from the casing a, the nut w is unscrewed and the lamp may then be eX tracted from the casing.

The piece n, of pyrophorous alloy may readily be replaced after the lamp has been withdrawn. To this end it is only necessary, as is obvious, to press the lever k, downwardly thereby to remove the end thereofl from the socket g, whereupon a fresh piece of alloy may be inserted.

laims.
