FIRE-EXTINGUISHING APPARATUS.

Specification of Letters Patent.

Patented April 24, 1906.

Original application ledApril 20, 1892, Serial 110.429,825. Divided and this application filed September 4, 1901. Serial No. '74,335-

To all whom it may concern:

Beit known that I, CHARLES E. BUELL, of North Plainield, Somerset county, State of New Jersey, have invented Improvements in Fire-Extinguishing Apparatus, of which the following is a speclication, the same being a division of my application for {ire-extinguishers filed April 20, 1892, Serial No. 429,825.

My invention consists, primarily, in the combination, with a system of automatic sprinklers, of a main valve apparatus closing the Waterway between the main supply pipe and the distributin -pipes, thermally-actuated devices norma ly sealing the distributing-pipes, an alarm apparatus held normally out of effective action by a valvular mechanism that is adapted to be moved by the variation of pressure in the pipes of the system due to the opening of a sprinkler and when so moved to bring said alarm apparatus into effective action, substantially as hereinafter described.

My invention further `consists in the com bination, with the pipes of a sprinkler system, of a means for admitting water thereto from a main supply, a pressure-controlled apparatus having connection to an alarm apparatus and adapted to admit water to said alarm apparatus when a sprinkler opens and the pressurein the system varies, substantially as hereinafter described.

` My invention further consists in the combination, with the pipes of a sprinkler system, of a water-motor having connection to said pipes through a pressure-actuated apparatus that in its normal operation admits Water to said motor when the pressure in the system is varied by the opening of a sprinkler and an electric generator in operative relation to said motor, the whole arranged and operating substantially as hereinafter described.

In the accompanying drawing the figure represents a sprinkler system having the main riser P, connecting between the main supply-pipe M and the tank T and comprising a double bend constituting a Siphon by means of which the water from the tank T can be held by air-pressure from entering into and illin the riser P until a sprinkler melts open an allows the air-pressure to esing gage G, having connection to the riser P and by its index-hand to operate an electric circuit in which is included the electric bell G and battery B when the pressure in riser P falls below a predetermined point. There is also shown a water-motor W M attached to the alternating-current electric generator D and provided with a bell b and hammer h for sounding a local alarm when the motor is in motion and for generatin(y currents for charging the' circuit composed of Wires W W to sound a distant alarm when the motor is given motion by the entrance of water thereto through the pipe P2, which has connection to the system through the pressure-actuated valve V and the attached combined piston and valve V in the cylinder A.

A check-valve C V is shown located in the branch of the main supply which leads to the steam-pump (not shown) to prevent the escape of the air-pressure in the system.

The operation of the apparatus is as follows: When a sprinkler S S opens, the Water in tank T flows to iill riser P and through pipe P3 to beneath-the combined piston and valve V, which by its large area for pressure raises valve V, admitting water from main M to supply the system and also admitting water to pipe P2 for iving motion to motor W M. A valve R is s iown at the inlet of the large pipe ofthe Siphon in tank T to prevent overflow of the tank when the water from main M is admitted to the system. There are also shown the feed-pipe and overfiowpipe for regulating the flow of water to and sure of water from the pipes leading' from the roo local supply to the distributing-pipes, as this is disclosed and claimed in my main application above referred to.

What I claim is'- 1. The combination with a system of automatic sprinklers, of a main-valve mechanism, means for automatically operating the said valve mechanism by variatlons of pressure in the pipes ofthe system, a motor havino connection to said system through the ave mechanism, an electric generator connected to the said motor and circuit connections joined to said generator.

2. The combination with a sprinkler system of a mechanism for giving fire-alarms when a sprinkler opens by heat that comprises a motor operated by water admitted thereto. automatically bya lowering of pressure in the pipes of the system, a generator of electricity driven by said motor, and having connections to an alarm apparatus, and an alarm ap aratus having connection to the pipes of t e system through a pressure-indieating device that is independent of `the said motor.

3. The combination with an incased valve normally excluding Water from the pipes of a sprinkler system, of a tank located above said valve and having a siphon connection thereto and to the system of sprinklers, means for maintaining air-pressure normally in the system that is adapted to prevent water from the tank acting to raise said valve until the pressure in the system is destroyed by the o ening of a sprinkler, a water-motor provide with connections to an alarm apparatus, and pipe connections from said watermotor to the interior of the casing of said valve.

4. In a lire-extinguishing system the combination with a valve mechanism for normally excluding the Water from the system, of a main supplyipe, a main riser-pipe, and a valve closing t e waterway between the said pi es, connections from the main riser to a supp y of gaseous pressure, and a connection .-om --tnelsaidwalve mechanism to a combined Water-motor and electric generator, the whole arranged and operating substantially as described.

.5. An alarm for automatic sprinklers comprising a dry-pipe-valve mechanism with pipe connections from the said. mechanism at a point from which the water is normally excluded to a water-motor, an electric generator adapted to be operated by said motor, Wire connections to a remote point, and a local alarm that is adapted to be made operative by the said motor.

6. The combination with a s stem oi sprinklers, of a tank located a )ove the sprinklers, means for maintaining gaseous pressure to normally hold the water from entering i'rom the said tank into the said pipes, an auxiliary su ply of water that is normally turned ofi an a valve for controlling the same that is adapted to be operated by the pressure from the tank to turn on the auxiliary water-supply when a sprinkler opens, a water-motor having connection to the system and adapted to receive water therefrom when the water from the tank operates the valve controlling the auxiliary sup ly, and an electric generator in operative reiation to said motor for transmitting alarm-signals to denote the movement ot said valve.

7. In a pressure-utilizing system the combination of a dry-pipe valve for normally closing the waterway between the main supply and the pipes of the system, thermallyactuated devices sealing the distributingpipes of the system, a'pressure-controlled alarm apparatus connected to the system and mechanism for operating the main valve and normally excluding water from said alarm apparatus and adapted to admit Water to said apparatus when a sprinkler opens.
