To all whom t may concert/.5 l

Beit known that I, SAMUEL JACKSON, Jr., a' citizenot1 the United States, residing in Philadelphia, Pennsylvania, have invented certain r 5 Improvements in Fusees, of lwhich the folle-y ing is a specification. N

M y invention relates to that class of fusees especially used as signals on railroads` or Ships or for pyrotechnic displays. Y

ro -The fusee is` mainly used Yon railroadsby the rear brakeman of a train who ignitesthe' fusee and throws lit from the rear of the train,

or, if the train has slowed up, fastens itfin vthe ties or uses it as a hand-signal, as circumstances require.

The object of lny inyention is to make a cheap and practical fusee that can be ignited .readily by percussion, ivliiclrwill be Waterproof, and from which thematerial cannot zo be dislodged by the-actionrof throwing.r the fusee from thetrain. `Thisobjeet I attain in the following manner, reference being had to the accompanying drawings, in which- YIgure 1 isa'view, partly in section,of my z5 improved fusee, showing the cap applied. Fig. 2 is anenlarged sectional View ofthe head of the fusee. Fig. d isa View showingA the method o ,f igniting the same, and'Fig. 4

is a view showing the methodof wrapping the" 3o waterproof material Within the casing.

A is the casingof the fusee. Thiscasing is made of ash'eetof` paper vrolledup into form, as clearly indicated in Figft. In order to make this casing Waterproof, I insert in the roll of paper A a sheet of Waterproofpaper -such, for instanc'efas,parafnpaper-and of such a length that when rolled up with the paper of the casing itwill: form a Waterproof lining between the inner and outer folds of 4o the paper A' forming the'casing.

Secured to one end of the'cas'ingA is a plug a, of wood orother material, having eithera spike ot', asslioWn-infull lines inllig.1,'o ra handle, as .shown in dotted lines inv said iig` ure. If the fusee'fis to beused as a hand-signal, then the'handle form is preferable; but it' it is to lbe used-as a fixed signal on a'track, for instance, then the spiked-form is preferable. Y

5o Within vthe fusee is a slow-burning illuminating material B, preferably in powdered `form and of the desired colo'r.- In'the present instance the fusees are made with the illuminating material of a red color, indicating danger. ing illuminating material which is made,pref era'oly, in the form of apaste and inserted in the end of the fusee upon the slow-burning material, and this quick burning material solidies and acts as a plug D for the end of 6o the fusee, preventing the loose slow-burning material from escaping, and as this material Ais Waterproof it also prevents moisture gaining access to the slow-burning material. It sometimes occurs When this material is ig- .nited and the fusee thrown from a train that the'pl'ug of quick-burning material becomes loose, and consequently the fusee is useless. To overcome this objection, the plug D is fastened by a transverse pin d. This 7o pin is inserted in the material when it is soft,

so that when the material becomes hard the pin holds it securely inthe casing. On the end of this quick-burning material D is an igniting compound e-such, forinstance, as used on a parlor-matchor other material `Which will ignite by percussion.

,Y In order to hold the material Within the fusee, I place over the end ,of'the casing a muslin coverf and cement said cover to the 8o casing. Inclosing the end of the casing is a protective cap A2, preferably made of paper fand having a Wooden end e2, provided with Va cavity, so that when said cap is placed in position over the end of the fusee it Will not touch the ignitible part of the latter, but Will protect it from injury, the cap resting upon the end of the fusee-casing. Such construca tion permitsfthetransportation of the fusee Without'danger. 9o :The fusee cannot be ignited until the cap Yis removed, when by Simply'striking thefend of the fusee upona hard substance-su'ch, for instance,pas the hand-rail ofja` Vcan-Las shovvn inFig. 3-the materialwill readily ig- 95 nite, the ycpiick-burning compound being first consumed during the time that it takes to place the fusee in position on the track or While it is being thrown from the car. As

soon as the quick-burning material is con- Ioo At the end of the fusee is aquick-burn- 55` sumed the slow-burning material is ignited, and the fusee will then give a steady light fora given length of time, depending upon the amount of illuminating material carried Within the casing.

I claim as my inventionl. The combination in a fusee, of a casing, a mass of slow-burning material Witllin the saine, a mass of quick-bu rning material carried by the casing and having a portion projecting in tapering form beyond the end of said casing, and an ignitible substance Secured permanently at the smaller end of the tapering projection and adapted to be ignited by percussion.

2. The combination in a fusee, of a casing, a mass of slow-burning material and a mass of quick-burning material Within the casing, the latter mass solidifying after insertionl and retaining the slow-burning material in place,

and an iguitible substance secured perma-r nently at the end of the quick-burning material and adapted to be ignited by percussion, substantially as described.

3. The combination in afusee, of acasing, a mass otl slow-burning material and a mass of quick-burning material within the casing, the latter mass solidifying after insertion and forming a plug to retain the slow-burning material in place, an'ignitible substance Secured permanently at the end of the quickburning material and adapted to be ignited by percussion, and a fabric covering for the end of the easing, said cover inclosing both lVitnesses:
