To all whom it may concern:

Be it known that I, JoHN THOMAS NAGLE, a citizen of the United States, residing at Butte, (post-office address,) in the county of Silver Bow and State of Montana, have invented certain new'and useful Improvements in Igniting Devices for Fuses; and I do herebydeclare that the following is a full, clear, and exact description of the same,-reference l to being bad to the annexed drawings, making view of a fnse-igniter constructed in accordance with my invention and showing the end of the fuse connected thereto; Fig. i, a longitudinal section of the device with the fuse removed. In the accompanying drawings, A represents a tube of copper or other metal or of any suitable material found best adapted to the purpose, whichtube may be of any desirable length and of a diameter to properly fit over the end of the fuse, as shown in Fig. 1 of the drawings. One end of the tube A has a filling C of any suitable combustible composition, but preferably of a composition consisting of the following ingredients: sulfur, one part; sugar, one part; bichromate o potash, one part; oxid manganese, one part; chlorate potash, sixteen parts; litharge, six parts; charcoal willow,- four parts; acacia, our parts. The tube A is supplied with this composition :1; portion of its length, leavinga space back of it for the reception of the end -of the fuse, as indicated at B in Fig. lot the drawings. The composite combustible filling C extends beyond the end of the tnbe,so that a portion will be exposed forconvenience in igniting it by means of a friction-match 5o tip D, which is embedded in the composition and projects a suflicient distance from the same; so that it may be convenientlyignited by friction. The tip D may be composed of any of the well-known friction-match compounds as found most preferable. i The exposed port-ion of the fillingCor that which extends beyond the end of the tube A forms a composite head and not being con fined within the tube renders the ignition 6- thereof more certain when the match-tip is ignited. 4 The exposed portion of the filling C and the match-tipDare rendered impervious to moisture by a coating E of paratfin or other snitable waterproof substance. This device to which the fuse is connected is both simple and comparatively inexpensive, and the ignition of the fuse is certain and reliable without danger or risk to the operator from premature explosion.

Having now fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is e An igniting device for fuses, consisting of 15 a suitable tube, a composite combustiblefill ing therein extending beyond one end of the tube to form an exposed portion, a frictionmatch tip embedded in the composite filling, 7

and a waterprooficoating covering the ex posed portions of the filling and the matchtip, substantially as and for the purpose set forth. r

In testimony that I claim the foregping as myown I have hereto affixed my signature in the presence of two witnesses.

- JOHN THOMAS NAGLE.
