ali whom, it may-concern: .Be vit known that I, JEAN PIERRE ALEX- EDRE SCOLA, of the city of Paris, France,
following is a full, clear, 'andexact descrip- This 'invention relates to electric lightingfuses or lighters for use in blasting by means ef'gunpowder or dynamite in 'mines generally, but more especiallyin coal-mines liable to the presence of fire-damp. These lighters entirely obviatc the\ use of fuses of all kinds which require to be ignited by a flame. ,They' are also more economical, and a great saving of time is eected, especially in thecase of Vmis-lires, as the lighter can be immediately replaced withoutthe liability of accidents, such as are ordinarily caused in drawing the charges, which can only be done after an interval .of twenty-four hours. Moreover, 'as several shots can be red instantaneously, no loss of time' is incurred by the workmen. '-Reference is to be had to the accompanying drawings, formingpart of this specification, which illustrate an example or" the invention. I
`Figure l represents the plug used with the lighter of this invention,with the conductingwires attached. Fig. 2 is a plan of the same, andFig. 3 a horizontal section on line 1 2 of Fig.'1. Fig. a is a longitudinal section, and
Thesame letters of reference represent the Same parts in allthe figures. "-lhe lighter is composed of a grooved plug,
wires d, -which are first twisted together at the inner end of the plug and then laid in the to o'ne another at the outerv end of the plug, The wire at the inner end of the plug is then naked,l so as to leave the twoends exposed, which are then flattened' down. The plug is inclosed in a paper sheath, e, a charge the closed end of the sheath inclosing the produced on the passage of the current between the naked ends of the wires ignites the fulminate. The electric lighter is introduced into a tube, a, of copper or pasteboard,.pro
senti NDL 196,154. (No moan vided with a quick-match, g, which is ignited and projected bythe fulminate into the hole and fires the charge of .powder placed therein.
For firing dynamite, the lighter is modified as follows: The pasteboard tube is dispensed with and the. plug is introduced into an ordinary detonating capsule containing` a fulminate. The electric lighter'is separated from thefulminate by a space of from four to six millimeters, so as to avoid accident caused by friction or otherwise. The capsule thus prepared is inserted in the charge in the ordinary way, the additional advantage. however. being obtained of freedom from liability of iguiting the priming f, which is the cause ofso much loss of time and materiabas'well as of danger when drawing mis-lires. The electric priming will, in fact, either instantaneously produce an explosion or not at all,an d there will be no risk attending the immediate renewal of the priming or withdrawal of the Y charge.- y y Any kind of electrical apparatus ,may be employed for exploding these lighters; but it' is preferred to use those by means o'f which several shots, either of powder or dynamite,
may be iired simultaneously.
It will be evident that the herein-described arrangements may be applied for producing the ignition of a Bickford fuse, which would in-this case be substituted for the quick-match g in tube a'thereby avoiding the use of a naked flame.
I claim-v A i An electric lighting-fuse or lighter for blasting purposes, consisting inthe combination of the guide-tube a' with thev grooved wooden plug b, the conducting-wires d, the fulminate f, above said plug, the paper, or other sheath or cap c, and quick-match g, the sheath or cap e, containing the plug b, the wires d,.and the fulminatef, andbeing itself contained within JEAN PIERRE ALEXANDRE-SOMA.
