POCKET-LAM P.

SPECIFICATION forming part of Letters Patent No. 440,265, dated November 11, 1890.

Application filed May 17, 1890- Serial No. 352,154.

To all whom it may concern:

Be it known that we, ELIAS B. KOOPMAN and WILLIAM W. MOKENNEY, citizens of the United States, and residing at the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pocket-Lamps or Lighting Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part thereof, in which similar letters of reference designate like or equivalent parts wherever found throughout the several views.

This invention relates to that class of lam or lighting devices which are designed to be carried in the pocket, and may be used for lighting cigars, lamps, gas-burn ers, and many other similar purposes; and the invention, which is fully disclosed in the following specification, is an improvement on the construction shown in United States Letters Patent No. 414,058, issued to Elias B. Koopman, one of the applicants herein, October 29, 1889.

In the accompanyingdrawings, which form part of this specification, Figure 1 represents inelevation ourimproved lighting device, as it appears when opened. Fig. 2 represents a top plan view of the same, the cover being removed 5 and Fig. 3 represents a central V6ll3l cal section of our improved ignitible pellet or fulrninate carrier.

Referring to the drawings, A and B represent the separate sides of our improved pocketlamp or lighting device, which are hinged together at O, and D is the cover hinged to the back, which in this case is formed integral with the side B at E. The lamp is preferably substantially rectangular in cross-section, as is shown in Fig. 2, and to one of the side portions is attached the reservoir F, in which is placed the burning fluid or agent. This reservoir is provided with a hinged cover G, through which passes awick-tube H. The reservoir F is filled with an absorbent material, and a wick K is in contact therewith and extends up through the wick-tube and cover, as shown in Figs. 1 and 2, in such manner as to bring the wick into close proximity with the ignitor when the sides of the lamp are closed.

The ignitor-diskL is composed of adisk of paper, cloth, card-board, or other suitable (No model.)

material, upon which are arranged in a circle a number of pellets, drops, or bits of fulminate or explosive material or composition M.

These pellets are in our improvement arrangedin a circle on each side of the disk and preferably near the edge thereof.

The disk-carrier, to which the ignitor-disk L is attached, consists of a wheel N, mounted upon a pin or pinion O, which is attached to or extends through the side B of the case, and formed upon or attached to the carrierdisk N is a circular ratchet or toothed .wheel P, (shown in dotted lines in Fig. 1,) the car rier and ratchet being so united or constructed as to turn together on the pinion O. The

ignitible pellets or fulminates are so spaced as to correspond in position with the teeth on the ratchet, so that a fulminate is presented to the scratcher or ignitor at each movement of the carrier as the same is intermittently revolved. These ignitible pellets or fulminates are ignited by a spring-scratcher R, cut or stamped from sprin metal, preferably steel,

and curved, as shown, at one end of which is attached to the reservoir in such a position that the upper free end thereof when the sides of the case are closed together comes in contact with the disk L and the pellets or fulminates arranged thereon, and as the carrier is advanced step by step the fulminates are ignited as they pass under the end of the scratcher and the wick K is ignited.

The means employed by us to rotate the carrier consists of the spring-pawl S, one end of which attached to or is in contact with the puslrbutton T and the outer end of which engages the teeth on the ratchet-wheel P, and a spring U, attached to the side 13 of the easing, also engages the ratchet and prevents its 0 retroaction when freed from the spring-pawl S. A spring V is attached to the back of the casing in such a manner as to act upon the cover and open the same when released from engagement with the spring \V, attached to or in contact with the push-button T, by which the spring W is operated and lamp opened. It will thus be seen that the same movement that releases and throws open the cover also rotates the carrier, explodes afulminate, and mo lights the lamp.

The carrier=disk N, which carries the fulminate-disk L, is provided with projecting spring-fingers X X, preferably of ogee shape, as shown, the free ends of which extend in opposite directions and are curved outward, the pinion 0 also extending in the same direction to a distance equal to or greater than that to which such fingers X X extend. These fingers X X are preferably arranged on the carrier-disk N in line with the central opening through which the pinion 0 passes, and the ignitor-disk L is provided with openings or perforations which correspond with the positions of the pinion O, on which the carrier-disk N is mounted, and of the projecting fingers X X upon said carrier-disk N.

In placing the disk L in position upon the carrier-disk N it is only necessary to press the same down in the direction of the carrier till the pinion 0 passes through the central opening, and then gently rotate and pr ss upon it until the spring-fingers X X pass through the corresponding openings therein, when by giving the disk L another slight rotation the fingers will pass farther through said openings, and thus hold the disk L snugly against the carrier-disk N and the fingers X X, and the disk L will then be in the position shown in Figs. 1 and 2. The extension of the pinion 0 beyond the fingers X X aids materially in this operation.

By providing the disk L with pellets or fulminates on each of its sides and so constructing the disk as to admit of its being reversed upon the carrier and held securely in place in either position, the ignitible pellets or f ulminates being so arranged on either side of the disk L asto be exploded or ignited by the same automatic devices when the disk is in proper position, a great advantage is secured over the construct-ion shown in the patent hereinbefore referred to, not only in the value of the lamp and in the cost of its construct-ion, but also in the practical use thereof. It is also a great advantage over the construction shown in the patent hereinbefore referred to to provide a reservoir with a hinged cover and a wick which passes up through the cover in such manner as to bring the wick into proximity to the ignitor when the sides of the lamp are closed, as herein shown and described.

It is evident that many changes may be made in the details of construction and the arrangement of the parts of our lamp without departing from the scope of our invention, and we do not limit ourselves to the exact elements of construction and the combination of parts herein shown.

Having fully described our invention, what we claim, and desire to secure by Letters Patent, is the following:
