VTo ALL WHOM 1T MAY ooNoEsN: i

Be it known that I, JQHNSOUTHER, of the city of Boston, county of Suffolk, and State of Massachusetts', have invented a new and useful improvement, a machine, or a combination of machinery, for the purpose of more promptly giving n. fire-alarm, and extinguishing a lire. I do hereby declare that the folloiving description, specification, and accompanying drawings, is a true description of the construction and operation vof the same.

The object of my invention is, when a. building or vessel is on fire, to use the fire as the agent to give the alarm by a steamor gas-whistle, and also put out the fire byA steam, gas, Aor water, making it self-operating.

Drawing A, Figure 1, is a side elevation. l

Letter A, on drawing, represents a. steam or gas-pipe broken oft', which pipe leads to or from the steamboiler; B s a. steam-whistle ;V C is a. cock o r valve; D is aline or any combustible attachment leading across a room'or vessel, and secured there, sc asto raise the weight E olf the lever F, by passing over pulley G.

When `the fire comes in contact with `this attachment tosever it, it drops weight E snfll lever F, and opens valve C, and lets steam in the room, or'gas under pressure, coming in Contact of whistle, giving an alarm, and putting out the re lby the steam or acid gas. Water may be let on the re by the same motion.

H H is a gasgor steam-pipe brokeniofi, which pipe leads across the room or vessel, for the purpose ofletting on steam in different places in the building or vessel, by the heat of .the re melting a metallic fusible plug, I, which melts at a low degree of heat, and, when melted, lets steam through the apartment it covers; also by igniting a combustible fuse in opening of pipe marked J, and by the expansion of the pipe by the heat of the fire, thereby forcing valve-stem K against block L, opening the ,valve inwardly, letting out steam, all for the purpose abovenamed. i

1L A selioperating lire-alarm and extinguisher, consisting ofthe pipes A and H, vfhistle B, valve C, lever F, and weight E, o'r their equivalents, all constructed and arranged to operate substantially as herein described.

2. The pipes A and H, fusible plugs I and J, anll valve-stem K, constructed and arranged to operate substantially as herein described and for the purpose set forth.
