Specification of Letters Patent-1 Patented Sept. 20, 1910-.

Application fil'ed November 2, 1909. Serial No. 525,866.

To all whom it may concern:

Be it known that I, RENE OONINGS, a subject of the King of Belgium, and. a resident of Pittsburg, in the county. of Crawford and State of Kansas, have invented a new and Improved Fuse-Igniter, of which the following is a full, clear, and exact description. This invention relates to fuse 1gn1ters for use in mines and the like, to ignite the fuses used to detonate blasting or other explosive charges, and relates more particularly to a' fuse igniter having an igniting chamber, means for introducing the end" of a fuse into the chamber, and means for igniting the 'fuse within the chamber so that no flame or spark can escape from the device.

The object of the invention is to provide a simple, inexpensive and efficient fuse igniter, which can be easily and expeditiously manipulated, by means of which fuses can be ignited in. mines or the like, without danger of causing explosions due to the fir ing of accumulations of gas which may have collected in the neighborhood of a fuse, and which involves no loss of time or labor in the lighting of th e fuse.

I The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a 'partof this specifi-' cation, in which similar characters of reference indicate corresponding parts in all the views, and in which I Figure'l is 'a partial, longitudinal section of an embodiment of my invention, showing a-fuse associated therewith; Fig. 2 is a side elevation of the device; Fig. 3 is an enlarged end viewshowing the means for holding thefuse; Fig. 4 is. an enlarged, transversesection on the line H of Fig. 2; and Fig. 5 is a similar view' on the line 55 of Fig. 2.

Before proceeding to a more detailed exvarious parts of the-workings, and unless certain precautions are-taken these accumulations' of gas can easilybe ignited to result in dangerous explosions. 'To, obviate the possibility of such explosions, lamps known as Davys lamps are used, in -which the flames are -1ncased in wire gauze or other w 7 I dangerously explosiveoften accumulate in reticulate or-perforate hoods or covers,-

which in accordance with a well-known sclentific prm'ciple prevent the transmission of the flame to the outside of the gauze. I have employed this principle in my fuse igniter, which includes a chamber wherein the end of the fuse is received and ignited by suitable means, the chamber having a reticulate or perforate wall to permit. the entrance of the necessary air, though preventing the escape of flame or sparks to the outside. Referring'more particularly to the drawings, I employ a wick container 10 fashioned from sheet metal or the like and preferably of substantially cylindrical form, and pro- I vided with rounded extremities 11 and 12. The extremity 11 may be provided with an eye 13 by means of which the igniter can be hungupon a hook or can be attached to a' carrying loop or the like. The container has a closing slide 14 arranged to move in guides 15-, and provided with a projection 16 by means of which it can be manipulated. The slide serves to close the opening of the container, and permits the introduction into the same of the-wick 17. The end 12 of the container has associated therewith the wick tube 18 through which the wick 17 extends.

The wick tube intermediate its ends isextended to form a substantially cylindrical barrel "19 in which are journaled grooved rollers 20 adapted to gripthe wick and arranged to be manipulated from the outside of the'barrel'by means of a stem 21 having a burred head 22. By turning the head 22 .in one direction or the other, the wick is advanced longitudinally of the wick tube by means 'of the rollers which are suitably geared together in the usual manner The rollers are 0 rated by suitably incased gears (not shownii The igniting chamber 23 is preferably cy-i li'ndricalinform and has openings 24 at opposit e sides. These dpenings are covered with metal gauze-25 or thelike, which maybe of any suitable reticulate or perforate form. The igniting chamber has a neck 26 adapted to be slidably mounted at the end of the wick tube 12, and having a bayonet slot 27 adapted to co-act with a stud 28.0f the wick tube to hold the igniting) chamber removably in position. It will e understood that bymeansofthe advancing device the wick 17 can be moved into or retracted from the igniting chamber as desired. The wick is preferably of cotton, and when 1gn1ted merely smolders and is consumed slowly and radually. The end of tlie igniting cham er remote from the container is open and has mounted thereon a fixed jaw 29 having a substantially cylindrical, longitudinal groove 30 and at the ends laterally extended lips 31. The ignitin chamber has extensions 32 between whic is pivoted, by means of a suitable pin 33, a movable jaw 34 havin a longitudinal, substantially semi-circu ar groove 35 adapted to register w th the groove 30 to form a substantially circular opening in which part of the fuse 36 can be received. The jaw 34 has a handle37 by means of which it can be conveniently manipulated, the handle extending longitudinally of the device as is shown most clearly in Fig. 2. A sprin 38 tends to hold the movable jaw normal y closed. The movable jaw, it will be seen, seats against the fixed jaw between the lips 31 and the igniting chamber, so that when the end of a fuse is held between the jaws, air is excluded from entering the igniting chamber through the open ,endthereof.

The container of the igniter serves as the means for grasping it, the device being so proportioned that itcan be conveniently held in any Way with the thumb upon the handle 37. When it is desired to ignite a fuse the handle 37 is depressed to open the jaws, and the end of the fuse which has previously been split by means of a knife or other suitable tool, is inserted mto the igniting tube. The wick, which has been pre viously lighted, so that it is smoldering, is

then turned up until it is brought into engagement with the end of the fuse so that the latter is ignited. The'handle 37 is again depressed to release the fuse and the device is withdrawn. The operator then passes to a place of safety. It Wlll be understoodthat these operations can be performed in a very short space of time and that there is no danger of communicating the fire or sparks to any gas which may have accumulated in the neighborhood of the fuse, for the spark travels along within the fuse after the latter has been lighted at the split end.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent: I
