FLASH-LIGHT APPARATUS.

SPECIFICATION forming part of Letters Patent No. 571,632, dated November 17', 1896. Application filedMay 7,1896. $erial No. 590,566. (No model.)

1b ((,ZZ 107mm, i; may concern:

Be it known that I, J osnPH WOLF, a citizen of Germany, residing at Rochester, in the county of Monroe, in the State of New York, have invented an lniproved Flash-Light Apparatus, of which the following is a specification, reference being had to the accoinpauying drawings.

Myinventiou rola-tes to au iinpi'oved flashlight apparatus, which iinprovenient is fully describcd and illustrated in the following specification and the accoinpanying drawings, the novel features thereof being speciiied in the claiins annexed to the said specification.

My iinproved flash-light apparatus is represented in the accoinpanying drawings, in which- Figure l is a plan view. Fig. 2 is a side elevation. Fi g. is a central Vertical section on the line 3 8, Figs. 1 and 9. Fig. -l is an end eleration.

lily imp roved flash-light apparatus consists, essentially, of the air or gas supply pipe A, the reservoir l for conihustible powder, provided with the niovable bottoin O, the con'- necting-pipe D, the f nnnel E, and wiek F.

lin the operation of the apparatus a blast of air or gas through the pipe A carries some of the ooinbustible powder through the pipe D and discharges it against the opposite wall of the funnel, by which it is spread and distribnted so as to elnerge from the elongated month of the funnel, where it is ignited and prod u ces a wide, brillian t, and powerful fla-ine. By ele- Yating the niovable bottoin C in the reservoir as the comliustible powder is carried otf the duration of the flash may be prolonged for a considerable period of time. The blast of air or gas may be supplied in any suitable or preferred inanner.

The reservoir ll may be of any suitable shape or diinensions. lt is provided at its upper end with the hreinovable cap or cover ll, through which it is filled with the coinbustible powder. The pipes A and l) are inserted through the cap. The morable bottoui C is arranged to slide in the reservoir. lt may, if preferred, be provided with a rod by which it is elevated as the powder is used up. The pipe D is arranged so as to deliver the powder carried by the air-blast against the inside of the opposite wall of the funnel E at K, Fig. 3, from which point it is spread and distributed throughout, the current of air expanding laterally in the f unnel, so that it is diseharged from the month of the funnel in a wide thin sheet in condition to aiford a flash of large surface and great power. A suitable support F is arranged for the wiek along or around the elongated month of the funnel E. As shown, this support consists of a trough l, attached to the funnel E and filled with any suitable kind of a wiek. The trough preferably extends along both sides of the funnel, and thus the powder is blown directly through the iiainc, thereby insuringits entire colnbustion. In practicea l'ittle a-lcohol or other suitable liquid is poured on the wiek and i gnited and the powder is then blowu through the iiaine. The reservoir is filled with the coinb ustible powder, preferably powdered magnesiuin, nearly u p to the tubes A and D, and as the powder is used u p, either by shortor prolonged fiashes, the bottoin C is raised upward, so as to inaiutain the surface of the powder near the lower ends of the tuhes. It will, however, be understood that niy iniproved appa-ratus may be used with a reservoir having a solid bottoni. It will also be understood that the na-rrow funnel with inclined sides and the tube connected with it so as to discharge the powder against the opposite side may be used in connection with any suitable reservoir or iluid-supply device.

By the use of niy improved flash-light apparatus I secure a broad, brillia-nt, and powerful ilaine' of great illuininating power, and the duration of the flash may be prolonged to any extent required.

lI claim- 1. In a Hash-light apparatus, the powderreservoir, the adj ustable bottoin for the same, the air or gas inlet pipe, a powder-exit pipe, a funnel, an igniting device, said inlet and exit pipes connnnnicating directlyY with the upper surface of the powder and all combined substantially as set forth whereb-7 the powder may be dischargod by a blast on its unobstructed surface, and the charge inaintained at an approxiniately constant level, substantiallT as described.

The combination of the reservoir having IOO a removable Cap provided with an inlet andl its nnobstrueted surface,and the charge mainan exit, an air or gas inlet pipe, a powdertained at an approximately Constant level. io

exit pipe, both pipes terminat'ing in the cap, substantially as deseribed.

a funnel and an igniting device, and an adjustable bottom, whereby the reservoii' can J'OSEPH TOLF' be sepai'ated from its Cap and pipes, and filled Witnesses: v and the ppes and Cap replaced, and Whereby HOMER I-I. REICHENBACH,

the powder may be diseharged by a blast on GEO. B. SELDEN.
