PYROPHORDUS METAL.

tion.
This invention relates to an alloy of manganese and antimony constituting a pyrophorous metal. Hitherto these alloys have not been practically employed.
Experiments have proved that pure or commercial manganese will form an alloy with antimony in almost any proportions, if,
antimony be added for example to the molten manganese. F or the present purpose alloys containing more than 10 per cent. of antimony or of manganese are effective.
The formation of the spark is better than in the case of cerous iron, in this respect that, when rubbing or scratching is effected, besides sparks a kind of long blow-pipe flame is produced instead of a cluster of sparks, so that instead of its being necessary to arrange the friction-device and the flame directly one against the other, as in the case of cerous iron, it is possible to have a suiliciently great distance between them, so that the relatively hardened friction-device can be protected and not, as hitherto, be deprived of its hardness by the flame. A further advantage is that the new alloys are found to be air-proof, while at times cerousiron is seriously metamorphosed under the influence of the atmosphere and has a tendency to crumble.
A good effect may be exerted by adding certain metals, for 1nstance: chromium, up to 20%, but better less than 10%, titanium, up to 15%, but better less than 8%. For the sake of easier manufacture a little bit of Specification of Letters Patent.

Application filed August 24, 1910. Serial No. 578,715.
magnesium or aluminium may be added to the alloy.
Vhat I claim and desire tosecure by Let ters Patent 1. A pyrophorous metal, comprising an alloy of manganese and antimony containing more than 10 per cent. manganese.
2. A pyrophorous metal, comprising an alloy of manganese and antimony containing more than 10 per cent. antimony.
3. A pyrophorous metal, comprising an alloy of manganese and antimony, containing more than 10 per cent. manganese with an addition of othe metal.
4. A pyrophorous metal, comprising an alloy of manganese and antimony, containing more than 10 per cent. antimony with an addition of other metal.
5. A pyrophorous metal, comprising an alloy of manganese and antimony, containing more than 10 per cent. antimony with additions of other metals.
6. A pyrophorous metal, comprising an alloy of manganese and antimony, containing more than 10 per cent. manganese with additions of other metals.
7. A pyrophorous metal, comprising an alloy of manganese and antimony, containing more than 10 per cent. manganese, with addition of chromium up to 20 per cent.
8. A pyrophorous metal comprising an alloy of manganese and antimony, containing more than 10 per cent. antimony, with addition of chromium up to 20 per cent.
In testimony that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this ninth day of August 1910.
