HENRY s. PARMELEE, or New HAVEN, oossuc'ricu'r.

FIRE-EXTINGUISHER,

Be it known that I, HENRY S. PARMELEE', of New Haven, in the county of New Haven and State of Connecticut, have invented "a new Iniproveinentin FireqEx-linguishers'; and I do hereby declare that the following, when taken in connection-with the accompanying drawing and the letters of relerence marked thereon,

to be a full, clear, and exact description of the same, and which drawing constitutes part of this speciflcatiomand represents a sectional view of the apparatus.

- This invention relates to adevice for attachment to distributing-pipes in buildings for ex-;

tinguishing tires, the construction being such that the heat which may be generated in the apartment will automatically open the valve .and allow the discharge of water.

The invention consists, first, in a shield or cover by which theffusible inaterialis protected from a flow of water,'that theheat may other extinguishin jets.

the more" readily act thereon; second, iua device, in connection with the distributingqiipes,

fwhereby the full flow of water willbeanto- I matically let on so soon as one or more valves are open, and, in connection with the last named device, an alarm to be automatically sounded. 4 Y Y A is the main pipe, bywhich the water or diflerent points. a this pipe is avalve, B, by which the flow of wsteris cut Ofi'flhe valve-stem being held out in a closed position through a lever, D, as more daily hereinafter described.

E is the sprinkler, which consists of 'a hollow chamber numerouslyperforated, sov that pressure will beforced therefrom in numerous F is a valve standing below the chamber to the valve-stem, extends up, ,and over this a cap, H, is arranged, bearing upon the said spindle. Around the valve-chamber is a spiral s ring, I, the' springbeing attached to the cap by connecting devices L. These connecting devices are of a material which will fuse at a comparatively low temperature-say st160 or 200ofhenta 1 Through the capis an adiustlng-screw, N, which bears upon the spindle, so that by turnflnidis conducted to the I Application for reissue filed May 23, 1880.-

valve. The strength of this spring should be the water, or whatever the fluid may be.

The sprinklers E are arranged in different parts of the apartment whenever it may be desirable to discharge the water, and the water supplied thereto under pressure. If at any time a fire occurs in the, apartment, so soon as the heat has become so great as to fuse the connecting devices L on any one of the distribnters the pressure above the valve will he removed, and the water will then force the valve u'p, pass into the sprinklers E, and be thrown therefrom in jets.

In order that the jets from one sprinkler may not fall upon the connecting devices 11, and thus prevent the subsequent fusing ofanother.

There is liable to be more or less drip from the sprinklers by leakage from the valves. To prevent this from running down ordropping, a cup, d, is arrangedbeneaththe sprinkler E, into which the drip will pass,.and then may be wiped out, 0;, if a small quantity, it will evaporate.

In order to prevent the cold water, with which the valve F is always in contact, from communicating its low degree to the cap H, and thereby prevent as early :1. fusion of the connecting devices L as there would otherwise be, I place between the valve-stem and the cap a. non-conducting material, a.

The valve B is employed to cut 011' the principal communication between the pipe A and the distributers; and in order that the valve watergwhenever a fire occurs, I attach the valvelever D to the rod P of the piston R by means of a wire, 11. When the piston drops, a spring, '8, will draw the lever D forward and open the valve. The piston R is held up to secure the valve, and its action made automatic, in the following manner: From the supply-pipe below the valve B a tube, '1, of less area than one of the sprinklersyleuds to a littlegreater than the maximum pressure of sprinkler entering the connecting devices of;
