STATIONARY FIRE-EXTINGUISHER SYSTEM.

Specification of Letters llatent.`

Patented Uct. 7, 119113.

Application filed June 15, 1910. Serial No. 567,050.

T0 all whom I? may concern Be it known that I, ROBERTL. COONEY, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Stationary Fire-Extinguisher Systems, of which the following is a specification.

The present invention .is an improvement in stationary iire extinguisher systems and it involves certain novel features of my construction,arrangement and operation, conof reference designate which I am the originator and which, forming the bases of co-pending applications, Serial `Numbers .540,661 and 530,470, need only be described in a general way. In the eX- ample illustrated, the system includes a sta- 'tionarv chemical mixing tank, as 1, containing an acid bottle, as 2, and a distributing pipe, as 3, which leads from the tank and as 4, which projects there-- into. The tank is partially filled with an alkaline solution and the bottle 2 is mounted for inverting movement, being piyoted off center upon a'bracket 5.

With the mode of operation described in the applications aforesaid it is essential to provide for the maintenance of the pressures at equal degrees and for this purpose the pressures are normally in communication through a by-pass pipe, ras 6, which may .have a capillary bore or which may be, as shown, provided with a diaphragm 7,

having an aperture of pin-hole diameter.

The extension 4 and the pipe 3 are constructed to afford an enlarged chamber, as 8, which is preferably located above the solution level and which ineloses a ball, as 9. The lat-ter is, in' e'ect, a valve, and normally closes ,the mouth of the extension 4 which communicates with the chamber 8.

-.The ball 9.l is weighted to some exten-t for a purpose which will presently appear and is prevented from closing against the end `of posed guide Jinsufficient to ,the ball through the intermediary of the' the pipe 3, in communication with the ch amber 8, by a perforated web, asl 10, which bridges said chamber.

At one side of the chamber 8, a float chamber, as 11, is provided. The upperend of the chamber 11 is open and in communication with the tank. The lower end of the chamber 11 is provided with anI opening, as 12, having its wall formed as a valve seat and in communication with a passage, as 13,

afforded by a connection which extends downwardly from the chamber 8 to the chamber 11. W'ithin the chamber 11 is a float, as 14 having at its'lower end a valve boss-15, which, in the operation of the sys-l tem, closes against the wall. of the opening 12. The float 14 surrounds an axially dis.-

stem, 4as 14a and is held in a normal position by a body of liquid,- as16, which partially fills the chambers 8 and 11 and which is shiftable consequent to the .pneumatic impulse aforesaid but which is naturally at rest in its normal position. This body of lliquid is the equivalent of a mechanical element end is to be -so considered. The movement of the fioat 14 is consequentto the shifting of the body of liquid -16 and the operation of the system is direct-ly consequentY to the movement of the float. An advantageous means for eilectuating this result consists' of a lever 17, which is pivotedbetween its ends onI a bracket 18 and which has one end pivotally associated with the loat and its other end in latching engagement with a lug, as 19, which is provided at one side of the acid bottle.

From the foregoing description it will be readily apparent that when the body of liquid 16- is shifted so that its level in the chamber 8 is lowered, the float 14 will descend and in such movement will rock the lever 17 and release the acid bottle 2. The latter thereupon `inverts and discharges its contents intothe body of solution... The developed high pressure forces the solution from the tank and of course produces the displacement of the ball 9 and also acts on t-he doat to cause the valve boss 15 to seal the opening 12,v in order that there may be no appreciable escape of pressure therethrough in advance of the out-going column of liquid. The organization is of such nature that the operation may' be produced with an impulse of exceedingly light character and produce the displacement of instantly,

pulse but,

intervening body of solution. The -organi- 1zation is furthermore of such nature that it Having Jfully described my invention, I

claim? 1. A stationary dry-pipe iire extinguisher system comprising a tank, a distributing pipe communicating therewith, the tankcontaining a bodyv of liquid which is shiftable by a pneumatic impulse, a mechanical element which is movable to provide for the supplying of a fire extinguisher agent to the distributing pipe, a float supported by the body of liquid and operatively movable consequent to the 'shifting of the latter and a latch normally engaging the mechanical element and operatively connected to theA iloat whereby the descent of the, latter causes the disen agement of the latch.
