FIRE-EXTINGUISHER.
SPECIFICATION forming part of Letters Patent No. 254,271, dated February 28, 1882.
Application filed December 24, 1881. (No model.)
To all 'whom 'it may concern:
Be it known that we, ALBERT M. BURRITT and ANGELO C. BURRITT, of Waterbury, in the county of New Haven and State of Connecticut, have invented a new Improvement in Fire-Extinguishers and we do hereby declare the following,.when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be afull, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure 1, a longitudinal section of the distributer, showing the plug in the water-way Fig. 2, the ring detached; Fig. 3, the plug detached.
In fire-extinguishers which consist in a pipe extending through the apartment to be protected, with perforated distributers at different points, a plug is usually attached in the water-way by a fusible metal, or a fusible plug is secured' in the water-way, so that when the heat in the apartment rises toa certain degree the plug will be liberated and permit the water to iiow through the distributer to ex- A plug made of fusible metal is the best stop, for the water, but it is dieult to secure such a plug in the waterway hence a hard-metal plug is more generally employed, soldered to the walls of the water-way; but this hard plug is not so certain of beingliberated by the heat as the soft-metal plug, but is more readily secured to the walls.
The objectlof this invention is to producea soft or fusible metal plug with a hard-metal surface around its circumference, by means of which it may be soldered into the water-way, and in such a plug the invention consists.
We first prepare a ring, A, from hard metal, as brass, of a diameter corresponding to the internal diameter of the Water-wayB; then into this ring Awe secure a plug, C, of fusible material, such as usually employed for such plugs; then the plug C, with its hardmetal edge A, is introduced into the waterway, and there secured by solder in the usual manner for securing hard-metal plugs, as seen in Fig. l.
By this construction all liability of injuring the soft-metal plug in solderingit into the water-way is avoided, because the soldering is done upon the surface of the hard metal, and all the benefits of a fusible plug, combined with those of a hard-metal plug, are attained.
I claiml The hereindescribed improvement iu fireextinguishers, consisting ofthe plug composed of the hard-metal ring A and the fusible part C, lling said ring, and the plug secured in the water-way by means of said hard-metal ring,
substantially as described.
