PYROTECHNIC SIGNAL.

SPECIFICATION forming part of Letters P atent No. 385.562,*dated July 3, 1888.

Application tiled May 10, IESS. `Serial No. 273.402. (No model.)

To all whom it may concern.

tcrsburg, in the county of Din widdie and State of Virginia, have invented new and vuseful Im provements in lyrotechnics useful as Fire- \Vorks or for Signaling on Land or Water, of which the following is a specification. The object of my invention is to provide an article ol' fire-works that when ignited will emit smoke and flame accompanied with a loud and shrill whistle and succeeded by an explosion or detonation, either with or Without the ejection of stars,lcoloredballs, or rockets. An article ot this character is useful for general pyrotechnic purposes in parades and celebrations, as well as for signaling either on land or water, in fogs, at night, or asa distresscall in various circumstances,

My invention is illustrated in the annexed drawings, in which- Figure l is a partly sectional elevation of a piece of hand iireworks adapted to emit flame and smokcwith a loud whistling noise and provided with a bomb. Fig. 2 is a partly sectional view showing a moditication in the arrangement of the bom-b and handle. Fig. 3 is a partly sectional view of a form of construction that is especially adapted for signal purposes.

The numeral 1 designates a handle composed of wood or other suitable material and made any convcnientlength. Ina cheap form of construction, adapted for pyrotechnic displays, an ordinary pasteboard or paper tube, 2, Figs. land 2, will be attached to the handle l, so as to surround one end and project beyond the same a suitable distance. I do not confine myself, however, to a tube of pasteboard or paper, as any other suitable material can be used. An outer paper covering,3,may bc placed around the tube 2 and adjacent portion of the handle.

Vithin the tube 2 and resting on the handle l, as shown, isa bomb, 4, having an upwardprojecting fuse, 5; butit is obvious that instead of an ordinary detonating bomb, or, in connection therewith, one or more tire balls or stars ot' any desired color and well-known character may be located within the tube in a similar manner.

Above the bomb 4 or other suitable pyrotechnic, as shown in Figs. land 2, or surrounding the same, as in Fig. 3, isa tube, shell, 4or elongated hollow core,6,composed ot' wood, metal, tire-proof paper, or other suitable material-such as asbestus or lire-proof textile material. This tube or hollow core 6 is'preferabl y composed of wood,which maybe coated with a suitable lire-proof composition to prevent ignition and avoid accidents by tire when the piece is discharged.

The tube or-hollow core 6 is of considerable thickness, as shown, and has a comparatively small centraljbore which .is nearly filled with a fulminating compound or slow-burning py; rotechnic composition, 7, of any suitable or wellknown character capable ofemitting a large volume of smoke and flame when ig.- nited. The pyrotechnic composition, 7, is closely packed in the tube or hollow core 6 in the usual manner, and at one end it surrounds the fuse' of the bomb 4 or. other explosive. In the other end of the pyrctechnic 'composition, at the mouth'ot` the hollow core 6, is inserted a fuse, 8, through which the piece is ignited. The mouth of the hollow core 6 may be reamed or eountersuuk to afford a funnelshapcd air space or vent, 9, surrounding the ignitingfuse, and the outer covering, 3, of paper `or other suitable material, may be extended bey-ond the end 4of the tube and be twisted around the fuse, as shown.

The bomb 4. or other explosive device may rest directly on the adjacent endof the handle 1, between said handle and the hollow core 6, as shown in Fig. 1, a side support being *furnished wholly bythe tube 2, or the handle may be partly cut away to receive the bomb, as shown in Fig. 2. As shown in Fig. 3, the bomb 4 and tubular core 6 may both rest on the end of the handle, the bon'lb being surrounded by said core.,

Vhcn especially made for signaling pur poses, the entire article should be somewhat 9D- larger, as showninFig. 3, and more durable than for ordinary display, and metal may en/ ter more largely into its structure, particularly for the tube 2 and hollow core 6, which should bc suiliciently strong to withstand the pressure to which the pyroteehnic composition is subjected in the act of charging said tube. The tube may, however, be made of wood with an inner or outer covering of metal.

A by the handle and the fuse 8 ignited. n The combustion of the composition 7 in the comparativcly small bore causes an emission of c smoke and llame with aloud and shrill whistling sound, which renders the device particullarly valuable as a signal, cspecallyin fogs.

After the piece is ignited it should be waved or rotated steadily in the same manner as a Roman candle. c\Vhen the combustion of the composition contained in the hollow core' 6 has proceeded some time, the fuse 5 will become ignited and explode the bomb 4 or similar device with a loud noise and with snfeientforcc t o eject the core 6 and any fire-balls or star or rocket composition thatV may have been placed in the piece. It is .obvious that this iinal explosion adds to the efl'ectivcncssof the device, especially as a signal. 'If desired, the location of the bomb 4 and fuse 8 .may be re versed and the device used as a rocket.

1 AVhat I claim iS-` 1. An article ol lire-works comprising a liollow core having a small bore packed with a composition capable of emitting a large volu me of smoke and flame with a loud and shrill whistling sound, anigniting-l'usc in one end of said hollow corc,a -bomb or similar device at the other end of said hollow core, and a tube inclosing` said core and bomb, V'substantially as descri bed.

2. In an article of [irc-works, the combination ol' a handle, 1, a tubc, 2`, attached to said handle, a hollow core, 6, 'il'closcd in said tube and packed with a composition capable of emitting snloke and llame with a lond and shrill Whistling sound, a fuse in one end ol' said c0re,and a bomb or explosive atthe other end of Said core, substantiall y as described.

In testimony whereof- I have allixcd my signature in presence of two witnesses.
