POCKET-LAMP.

Specification of Letters Patent.

Patented Mar. 28, 1911.

Application filed June 11, 1910. Serial No. 566,392.

thereof is toprovide a compact and efficient form of device which may be readily carried by a person in thepocket for use when required to light cigars, pipes, and for other purposes, and which. is self-lighting, thus .dispensing with the use of matchesor the like.

Another object of the invention is to provide a lampso constructed that an inflammable vaporous liquid may be carried therein and conveyed to a burner by an absorbent wick which is ignited by a spark produced by frictional contact of two metallic bodies, and still another object of my invention is to provide a simplified type of lamp wherein is also employed a wick in the form of a fuse or other easily enkindled material, thereby overcoming the danger of accidents which are liable to occur from the use of vaporous combustible liquids.

A further object of the invention is to provide means adapted to effectually operate the two metallic bodies for frictionally producing the spark which ignites either or both of the wicks, and furthermore to provide a form of casing adapted to inclose the various parts of my lamp for safe conveyance by a person, and which will permit said lamp to be conveniently filled with the inflammable liquid, or fitted with the inflammable fuse. v

A practical embodiment of the invention "is represented in the accompanying drawing forming a part of this specification in which "similar characters of reference indicate correspondingparts in all the views, the said invention being more fully described hereinafter and then pointed out in the appended claims. Y 7

In the drawing, Figure 1 is a side View, partly fragmentary, of one form of pocket lamp embodying my invention. Fig. 2 is a view, transversely broken away, of the slide forming one of the side walls of the casing of my lamp, and Fig. is a section taken on the line IIII of Fig. 1. f

Within the casing 10 is provided a chamber 11, a tank or receptacle 12, and above said tank is arranged the means 13 adapted to operate the igniting means or metallic bodies 14 and 15 for producing the spark by frictional contact therebetween by which my lamp is lighted as will be hereinafter more fully described, and all of said parts may be of any desired-form and made of any suitable materials.

The casing 10 is substantially rectangular in shape and is formed of a body 16 and a cap or lid 17 which is hinged in any suitable manner, as at 18, to the body 16. The body 16 of the casing 10 has a side wall, as v19,

and end walls, as 20 and 21. At the opposed vertical edges of the

end walls

20 and 21 of the body 16 opposite to the wall 19 are arranged

fianges

22 and 23 under which are formed

grooves

24 and 25. In the grooves 24 and 25 a removable wall or slide 26 is adapted to be inserted for closing this part of said casing or to permit access to the in terior thereof, and upon'fione face of the slide 26 is provided a finger-knob, as at 27 by which said slide may be readily moved in the

grooves

24 and 25.

The tank 12 may be formed integral or made separate from the casing 10 and is a1 ranged upon the end wall 21, in the lower part of which is provided a cap or stopper 28 having an eye 1n which is held a ring 29 so that the lamp may be fastened to a chain or the like carried by a person. Uponthe upper part of the tank 12 is arranged a collar 3O projecting from the top of which is a burner 31 carrying a wick 32. After re moval of the stopper 28, the tank 12 may be filled with gasolene, or other va orous inflammable liquid which is adapte to-be ab:

ranged a spring 34 supporting the metallicbody 15 which consists of a spark-producing material composed of cerium or alloys of cerium which when abraded will throw oif a number of sparks. mally forces the block 15 of spark-producing material upwardly and outwardly through The spring 34 norsorbed by the wick 32 and'carried through I the top-opening of the tube 33, where the surface of said block 15 contacts with the serrated edge 35 of the wheel or metallic body 14. The serrated wheel or metallic body 14 is held to rotate upon a stud or shaft 37 fastened in a bracket 38 provided upon the upper part of the wall 19 of the body 16.

To operate the igniting means or metallic bodies 14 and 15 I arrange upon the shaft 37 and connect also to the serrated wheel 14 a toothed wheel 39 by which said serrated wheel 14 is rotated, and the toothed wheel 39 is operated by a cog-Wheel 40 rotatable upon a shaft 41 supported by the bracket To rotate the cog-wheel 40 and the toothed-wheel 39 with suflicient rapidity to cause the metallic bodies 14 and 15 to frictionally produce and throw-off a spark a toothed segment 42 is provided to operate the cog-wheel 40. This toothed segment 42 is rigidly fastened to one wall interiorly of the cap or lid 17 so as to move in unison therewith, and upon one face of said toothed segment is provided a pin 43 to which is held one end of a spring 44 directed across the face of the toothed segment 42 and into the body 16 of the casing 10 where the opposite end of said spring rests against the inner face of the wall 21 of said casing. It is clear that the spring 44 is adapted to control the movement of the lid 17 simultaneously with the movement of the toothed segment 42, and said spring is preferably of a form having sufiicient tension to swing the lid 17 with force from a closed position upon the body 16 to an open position, as shown in Fig. '1, whereby the toothed segment 42 will also be moved with force and in turn the cog-wheel 40 and the toothed wheel 39 will be rapidly rotated.

As previously mentioned my invention provides for dispensing with the use of any inflammable vaporous liquid in the tank 12, and instead thereof a fuse or wick 45 of other easily enkindled material may be employed to be lighted by the igniting means.

or conveniently carrying a suitable fuse, as 45, within the lamp the tank 12 is formed of a size and proportion with respect to the body 16 that the chamber 11 is provided to extend horizontally across 'and vertically at one side of the interior of the body 16 of the casing 10. To raise or lower the fuse 45 so as to be properly lighted, a wheel 46 is held to rotate upon a pin 47 held in a lug, as at 48, provided upon the wall 20 of the body 16, and this wheel 46 is formed with peripheral teeth 49 adapted to grip the fuse 45 when said wheel is rotated by the finger of a person;

In order to hold the lid 17 securely locked when closed upon the body 16, as indicated by dotted lines 50, a spring-catch 51 is connected at one end to theinterior of the wall 20 of said body, and upon the other end of said spring-catch is provided a clip 52 which is adapted to engage a notch or recessed part 513, formed in one wall of the lid 17. Projecting through an opening in the wall 20 is a push-button 54 which when pressed will force the spring-catch inwardly and out of engagement with the notch 52, thereby releasing the lid 17 from its locked position upon the body 16 and permitting the spring 44 to swing the lid open. Simultaneously with the opening of the lid 17 the spring 44 also operates the means 13, which in turn actuates the metallic bodies 14 and 15, and a spark is thrown therefrom'and ignites the wick 32, or the fuse 45, or both if desired. To extinguish the light of the wick 32 a tube 55 is arranged in the lid 17 and said tube is adapted to pass over the wick 32 and burner 31 when said lid is closed upon the body 16.

In the foregoing description I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myself the right'to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
