Specification of Letters Patent.

Patented Jan. 5, 1909.

Application led August 24, 1908. Serial No. 450,064.A

To all whom. it 'may concern:

Be it known that I, SUMTER' B. BATTEY,'a citizen of the United States, and a resident of the borough of Manhattan, city of New York, county and State of New York, have in'- veiited certain new and useful Improvements in Pocket-Lighters'.

This invention relates to self-igniters and more particularly to self contained portable pocket lighters for lighting cigars and for other purposes.

An object is to increase the reliability of such a device, more especially, to increase the reliability inthe self-ignition of avapor burner provided with a catalytic agent.

To these ends it is an object to provide for the positive delivery, at the will of the o erator, of inflammable gaseous medium, W 'ch term includes xed gases and inilammable vapors, to the burner and to the catalytic agent.

A further object is to provide for the permarient separation of the burner and igniting body from theI interior of the vessel containing the source-'of inflammable gaseous medium.

The invention also contemplates the adaptation of a Bunsen burner for use in a pocket lighter; also the combination with a self-igniting burner of a second burner for m`ore continuous use; also the use of a carburetor of ppsitive action for generating the inflamle/.vapor .for the self-igniter. ln addition, it is the object of the invention to improve the general construction of self-igniters and to do awaywith thenecessity of seperating respective .parts in their opera-v tion.

The above and further objects'will be apparent fromv the iollowingd'escription and claims read in connection with .the accom. 'panying drawings which form part of this application, in which'like characters designate corresponding parts, and in which, n Figure 1 is a sectional elevation of one` form o f my device; Fig. 2 is a similar view of a modification; Fig.r 3 is a similar view showing modified partsand an additional. burner;

Fig. 4' is a cross-section on line 4lill-FV of- Fig. 3; Fig. 5 is a side view of'a modified outer shell; Fig. 6 is a fra mentary vertical section through the two s ells showin the modiiicationof Fig. 5; and Fig. ,7 a etail `of the chck` valve. In the drawings 1 l designates a hollow shell scribed. This packing may be saturated with a liquid capable of producing an inflammable gaseous medium such ashydro-carbon vapor.

a unsen burner, as illustrated, and may be provided with the deflecting removable hood 8, providing the burner opening 9. It should be understood, however, 'that the burner may be used without the hood 8 if desired. Abody of material capable of cataignated by 10, in the form of a pellet which may be of platinum 'sponge or any suitable substance. This pellet may have projecting therefrom one or more brushes 11, formed of attenuated threads of platinum or the like. The pellet is suitably supported by" platinum yoke 13 frictionally engaging the inner walls A duct 15 leads from the pin hole opening 16 through the wall of the shell 2 to the interior of the Bunsen burner. 'Lbeneath the catalytic agent 10. If desired-the duct 15 may be upas indicated, and its exit opening may be covered by a wire gauze 17 to revent back ring', it being understood t ,at the wire gauze may be omitted or otherwise located if esired. 'V j InFig. 1 a nipple 18is illustrated,providing an opening 19 into the chamber within the shellsl yand 2. Threaded upon the nipple 18 openings 21 whereb the unscrewin of the the atmosphere and the screwing. down of the cap closes the duct 19. Provisions are also 16' o the duct 15. In-Fi 1 the rim 22 of the shell 1 itssnugly over he openingl l when the shells are completely telescoped as formed by the shells and closures just de' of .the burner 7 and resting against therib 14. -V

Suitably secured to the outer shell 2 is a va or burner 7, which may bein the form of lyticaction, that is, a catalytic agent, is desthreads 12, secured to the arms of aring-like wardly directed within the Bunsen burner,v I

is a manually operable-cap 2O with side cap opens y,the cham er Within the s ells to present for closing the pin hole opening hereinafter be apparent. In this modifica-v tion the pin hole opening 16 pierces the wall of the ri 24, and a closure 27 may beattached to the rim 22 so as to travel in the*` interior of the rib 24. The closure 27 may have inherent resilience or may be resiliently pressed against the inner wall of the rib 24 by the resilience of the rim 22. This closure 27 also serves as a traveler or stop for limiting the relative movement in a longitudinal direction of the shells 1 and 2. Obviously the relative longitudinal movements of the shells4 1 and 2-are limited in extent to the travel of the closure or stop 27 in the longitudinal rib 24, although a rotary movement of theshell l permits the complete removal of the shell 1 when the stop 27 reaches the rib 26, the exit of the bayonet 'oint. n

In Fig. 2, a tu e 28 opening to the atmosphere at-29 extends longitudinally within the shell 2 and terminates in position kto be closed by a plug or Washer 30, which maybe afiixed to the bottom closure 3 of the shell 1. modification the packing 6 is provided with a v cylindrical opening 31 to ermit the'passage of the tube 28. If deslred, the -tube 28, which rovides van opening from the chamber wit n the shells to the atmos here, .may

be provided with an automatic c eck valve 32 ,-this valve being shown in detail in Fig. 7. It maybe of any suitable construction'. That illustrated comprises a disk-like closure 33 wlth upwardlyi projecting and inturne fingers 34 which take over the crimped ed 35 of the mouth'of the tube 28. The tube 28 may be fixed in position in any suitable manner. In Fig. 2 1t may be soldered or brazed to the inturned nipple 35, or it may be expanded and spun over the opening in the closure 5, las shown by 36 in Fig. 3. If deslred the packing of absorbent material may be omitted and suitable vaporizable liquid may be contained directly in the vessel formed by the shell 1 and the closure 3. This is indicated by 37 iny Figs. 3 and 4. When provided forcovering the burner 38 and ma beY secured thereto by a chain 45. The tan 41 is fixed to the outer shellv 2.by soldering or brazing, and has supporting feet 46.

The, chamber within the shells 1 and 2 serves as la ysource of supply for an inflammable gaseous medium. This medium may be developed from any suitable hydro-carbon to be contained within the vessel. In telcsco ing, shells 1 and 2 as previously describe With their closures, form an hermeticallly sealed chamber for the vapor producing medium. To operate the lighter the shells 1 and 2 are extended one from the 'other by grasping the rim- 4 of shell 1 and pulling them out an extent indicated by the 'travel of the vstop 27 in the rib 24 of Figs. 5 and 6, as previously described, thisextent of opening being .approximate for all the embodiments, itbeing understood that the lower wall of olset rib 25 cooperating with stop 27 kmerely illustrates means for preventing the complete separat-ion of the shells during the operation of the lighten Before pu ing apart the shells 1 and 2 of the device shown in Fig. 1, the cap 2() should be unscrewed to open the duct v19, whereupon, on the pulling' apart of the shells, a jet of air is directed a ainst the. vaporizable material within the s ells, the arts operating as a. carbureter to roduce tli ble vapor. In v all t e embodiments the initial pulling apart of the shells uncovers the opening 16, of the duct 15, which opening itself may likewise serve as an ingress to air. The entering air immediately eiects the vaporization of the li uid lwithin the shells, whereupon the two s ells may be pressed telesto-picallyr together by thumb and linger pressure upon the closures?, and 5. In the modification. shown in Fig. 1 the cap 20 should first be closed uponthe opening 19, in thel modification' shown in Fig. 2 the linger or thumb serves as a closure for the opening 29,' and likewise in the modiication shown in Fig. 3. The shells constituteA means for com ressing the measured charge of inflammablb gaseous medium in the chamber they form and this means operates to force out a small jet through the minute orifice or pinhole opening 16 into the duct 15 which serves as an expansion duct in which the inflammable vapor is rendereduniform in composition and ex )ands so as to reduce its pressure to a desiredi-working pressure for supplying the burner 7. In the type of burner lllustrated the vapor is well mixed with air entering the bottom of the burner about the duct 15 and burns with an intense llame. The minuteness of the orifice 16 requires that an appreciable duration of pressure be applied to collapse the shells 1 and 2 and consequently prevents the too sudden delivery of vapor to the burner and its consequent waste.

e inflamma- I to the igniter.

vapor mayibe'produced'pritively and at will and it may be delivered-'positively and at will and in measured quantities to the burner and 'lhe igniter is shown as a catalytic agent a ainst which the vapor is first positively deivered in the resence of air. It is instantaneously heatellby a process well known for a decade.

Incandescence is imparted to the platinum brushes 11 and the vapor is ignited and con.

tinues to burn at the mouth of the burner opening 9 as long as vapor is supplied to it. At all times all the fragile parts are protected and to operate the device no parts are sepa-` In Figs. y2 and 3 the closure 5 is shown conical in formythus presenting a comparatively restricted surface 47 about the opening 29 which is a provision for closing the opening 29 by the operators finger or thumb. When the tube 28 is provided with a check valve 32 it` is not necessary that the operators fin er close the opening 29.

f it is desired that a more continuous flame be provided, the combination shown in Figs. 3 and 4 may be em loyed. If the cap 44 is removed the expose end of the wick 42 will be lighted by the flame issuing from the y lburner opening 9 and the burner 38 may be employe to sup ly a continuous iiame.

The pocket lig ter may be readily charged V with vaporizableliquid by entirely removing the bottom shell' 1 and iillin it with suitable liquid, whereupon it is rep aced within the shell 2n Although there have been illustrated and described several embodiments ofsthe invention, it is tobe understood that these are for purposes ofillustration only, and that the Vvarious elements shown in the several figures may be combined in a manner other than l that illustrated.
