PATENT Orrrou.
GEORGE M. MOWBRAY, OFINORTH ADAMS, MASSACHUSETTS.
Specification forming part of Letters Patent No. 161.480, dated March 30, 1875; application filed March 19, 1873 CASE 0.
To all whom it may concern:
Be it known that I, GEORGE M. MOWBRAY, of North Adams, in the county of Berkshire and State of Massachusetts, have invented an Improved Priming for Electric Fuses, of which the following is a specification:
lhe nature of my invention is a composition of matter, being a mixture of the double fulminate of metallic antimony and mercury with fnlmiuate of mercury in a tine state of division, and finely-divided metallic antimony and traces of an amalgam of mercury and-antimony.
I take mercuric fuhninate and grind the crystals witha soft cork under water in a porcelain mortar, so as to reduce it to a fine state of division. I next reduce antimony to a fine state of division, by using a smoothing-file, and passing it lightly over the metallic antimony, or, if not quite fine enough, by grinding the filings, with alcohol, on a ground-glass plate. One part of mercuric fulminate is then mixed with from two to five parts (both by weight) of the metallic antimony, an the mixture introduced into a porcelain evaporating basin. Cold distilled water is then poured over the mixture, and digested for twelve hours at a temperature not to exceed 60, for at 70 Fahrenheit I find bubbles of hydrogen are given on; indicating oxidation of the antimony, which I prefer to avoid. During this digestion the mixture should be frequently stirred. The pasty mass may now be thrown on a filter, for the antimonic fuhninate is nearly insoluble, and dried in a current of dry air.
Of the dried compound from half to one grain introduced between the terminal or dis-' charging wiresleading from a friction electric battery or induction-coil; and secured so as to prevent dispersion by the force of the dis charge, on operating the machine and passing a spark between the terminals, through the mixture, explosion ensues. Theterminals may but it may be manipulated with less precaution.
Without limiting myself to any precise proportions of either of the several ingredients,
A composition of metallic antimony and fulminateof mercury, as a priming for electric fuses, substantially as described.
GEORGE M. MoWBnAY'.
