To all whom it may concern:

Be it known that I, HENRY S. PARMELEE, of the city and connty of New Haven, and

State Connecticut, have' invented a new and useful Improvement .in 'Fire- Extinguisherm i and I do hereby declare the'following, when taken in connection with the accompanying drawing and .the letters of reference 'marked thereon, to be a full, clear, and exact descrip tion of the same, aud 'which' said drawing con stitutes part of this speciticali'on, .and represents a s'ectional side View; i e

This invention consists in the combinetion, with a distributer of water under pressure (or .other fire-extinguishing agent) and a hard-metai cap, which is able to copfine the extinguishing agent and is secred solder fusible at a low the efl'ect of a fire in the room where the extingnisher is placed, will release 'the cap, and the extinguishing agent will he permitted to discharge through the distributer.

It futher consists in constructing the distributer with a recess or neck between itand its base, and with the distributer perforated, o as to scatter the water in a spray over a large area in directions upward, downward 4 4 7 and lateral; and it further consists n constructing the valve which actuates the alarm with a cylindrical projection below the seat, which nearly fills the opening through the seat, and so as not to allow a full flow of wa ter until the cylindrical projection has passed above the valve-seat, whereby an increased movement is given to the valve to act upon the alarm, as more fully hereinafter described.

In the drawing, A is the pipe or tube forming one of the branches extending from the water-supply main, to which the perforated distribnter is attached. Over the distributer the cap C (usually made of brass) is loosely fitted, and is Secured thereon by a metal or material fusible at a low degree-say one 120 but so as to make a tight joint and prevent the escape of-water, gas, or whatever may be contained in the pipe. To allow the water to be distributed in all directions in a fine spray I 'contract the distributer so as to form the neck n between the distributer and the base b, where the cap is secured, and I place a numto the distributer by temperature, which,

well as on the uppe' curved surface. i

On examinng the drawing it will. be ob'- served that the cap 0 nearly fitsvthe base b of .the '(listributer, and that a broadsurface is 'ber of'holes on the lower side ot' thehead, as I presented, on which the ;fnsihle naterialis placed to solder the cap to the distributer; hence the watercan only reach ,the thin upper edge of the ,fusible material 'with 'which 'the soldered jointis n'ade until the cap isreleased and has' passed beyond orentirely from the' distributer. v Therefore' the quantity of water which can reach 'the fu sible material 'is so small as no't'to nateriallyafl'ectgiits fusibility; ;So soon as this cap. shall. have become heated'to the previousIy-determid degree the material which secures it" in place will fuse, thus 'freeing the cap from its connection, and the pressure'wilhin thepipes will force the cap ofl' the dist'ibuter and thereby allow the water to flow freely through the said distributcr. This com pletes the first part' of my invention.

D is the valve arranged within the chauber E to fit' upon the seat F, in substantially the usual nanner, with the spindle G runniigout through the stuffing imanner, upon the under side of the valve isa cylind-ical projection, L, which nearly fills the opening through the valve-seat.

box; also, in the usual N is the inlet-through which the water or v whatever it may he i's to flow to the distributer; and in order to hold the valve at rest upon its seatthat is, to balance the valve-a slight opening, a, is made through the yalve, which will allow the water to flow through and fill the ehamber E on the back side of the valve hence so long as the distributer is closed the valve must also remain closed, but so soon as the cap is thrown' off the pressure upon the 'back ofthe valve will be removed and the valve will open to allow the free flow of the water.

To sound the alarm (here reprcsented as a 'steam-whistle actuated through the val ve-stem P) a. c'onside'rable 'motion ot'- the valve-spindle G is necessary, more than would uaturallybe given by the opening of the valve. By the addition of the cyliuder L of the valve the passage cannot be fully open until this part L of hence there must be given to the valve en adu `I 1o Iot :the distributer, to be loosened or removed'by heat,`as such, I am aware, .is not new, as

diti'oual movement, aoeording-to the leigth'of the part L,-ad this is 'sficient to give-the required movement to the larm. This completes the second port of my iuventou, and this is applieahle to other 'purposes than for ai fireextingu'sher, where it is desirable to sound an alarm. 4
