FIRE-EXTINGUISHING APPARATUS.

SPECIFICATION forming part of Letters Application filed August '13, 1896- To all whom it may concern.-

Be it known that I, CHARLES E. BUELL, of North Plainfield, Somerset county, State of New Jersey, have invented Improvements in Fire-Extinguishing Apparatus, of which the following is a specification.

In the accompanying drawings, Figures 1,

tails thereof for carrying out my invention.

Referring to Fig. 1, there is shown the easing H, in which there is a main valve V, normally closing the inlet of the supply-main M,

portion thereof.

The main-riser of the sprinkler system B is shown as entering to within the casing H below the inlet of main M.

I The supply-main M is provided with a controlling-valve S V and a pipe 19, connecting thesupply-main M with the casing H, that enters the supply-main M at a point between the said valve S V and the source of watersupply, and by this location of the entrance of pipe 19 into the main M admitting of the introduction of water into the casing H when the valve S V is closed.

The riser R isprovided with a controlling valve R V, a drip d, a branch pipe 19 with sprinkler S attached, a gage Gfor indicating the pressures in the system and for operating an alarm-circuit by the connections to w, and there is also an air-pump connected to riser R for producing air-pressure in the system. A flap-valve a o is shown in riser R for alarm purposes, to be hereinafter more fully described.

The valve R V is a necessary part of the apparatus, and without which the resetting of the valve V would be difficult, as it admits of closing the riser R from the casing H during the resetting of the valve V. Above the casing H there is shown a tank T, having a float-valve f i), normally closing the outlet of the pipe 19, which pipe is a vent for the casing H. There is also shown a siphon E, connecting the tank T with the riser R, the said siphon being provided with a checkvalve 0 'u for preventing backflow from the riser to tank T when water is admitted to the riser R and system. The drip dis located at a point in the system where it will allow the water therein to be drawn off for resetting the valve and for repairs.

Patent NO. 582,896, dated May 18, 1897.

Serial No. 602,620. (No model.)

The valve 1) is provided with guides r r, passing through the partition or web 6 e, and there are shown the dogs 1- r for interlocking with the ratchet-teeth on guides r 1' to prevent the valve V from again closing the inlet of pipe M after it has been raised until it has been released by the hand of a person entered through the hand-hole h, which is normally closed. The valve V, when raised to the position shown in dotted lines, can be made to close the inlet of the pipe 19, the said pipe also being provided with a way-cock w c for controlling the flow of water therethrough. The guides r r, with the catch 0, are illustrated in enlarged View. In the enlarged View a spring is shown to cause the dog to catch in the teeth of the guide r.

The apparatus being arranged, as shown, with the valve V closing the inlet of main M and water holding valve V to close said inlet, and with the tank T filled so as to close the outlet of vent-pipe p, the valves S V and R V being open and a pressure of air in the sprinkler system holding the water from risin g in siphon E, the system is adapted to automatically turn on a water-supply to be discharged at the sprinklers when any one of such sprinklers becomes open by the heat of an incipient fire and to exclude the water from the pipes of the system until such opening of the sprinkler occurs. The pressure of air from the air-pump being confined in the riser R and pipes of the system until a sprinkler opens acts to hold the water in tank T from rising in the siphon E, and the outlet of pipe 1) is held closed by the float-valve ft, thereby confining the entrapped water in the casing H, which by its pressure on the enlarged surface of the valve V prevents the flow of water from the inlet of the supply-main M, holding the waterway between main M and riser R closed until the air-pressure in the system is destroyed by the opening of a sprinkler, as described.

To reset the apparatus after it has been operated by the opening of a sprinkler, it is necessary to close the valve S V and drip the water out of the system and to close the waycock to c in pipe 19. After replacing the sprinkler that opened with a new sprinkler, the valve R V is closed, the air pumped into the riser R and system, the valve V replaced to close the inlet of main M, water introduced through pipe 1) to fill the casingH and through pipe 1) to fill tank T and cause float-valve ft to close the outlet of pipe 9). \Vhen this is done, the valves S V and R V are opened to give a free waterway from the supply-main M to the system of pipes and-are thus left open.

There are advantages in being able to change a dry-pipe system into a wet system during the summer months, as the water requires an appreciable time to enter a system of pipes in which air is held under pressure until a sprinkler opens, and by having the water standing in the pipes this valuable time is saved and water is delivered at once upon a fire by the opening of a sprinkler. This can be accomplished by leaving the valves S V and R V open and closing the waycocks w c and w c and check-valve c t.

The valve V is preferably a flexible metal plate, which will conform to the inlet of main M when forced down by the pressure of the entrapped water in easing ll. Being unattached and free to move, the valve V has advantages in its use over those valves that are attached to diaphragnis or fit closely in a cylinder and is not liable to be impeded in its movements and to fail to properly operate, as are those valves which are attached to a diaphragm or which fit a cylinder.

In Fig. 2 there is shown a casing ll with the inlet of the supply-main Mon a level with the web or partition 0 e of said casing and the valve V pressed to close the opening in the partition and to close the inlet of main M by water that is entrapped in the casing II through pipe p. There is shown a hood 71 (I, attached to and moving with the valve V, which is of advantage in directing the water which enters from main M to the outlet of riser R. The hood h (Z carries the elastic guides '7' 0', that are adapted to spring outward and engage with the ledge in the casing 11 and prevent an accidental resetting of the valve V. A hand-hole may be provided for resetting the valve V, as shown in Fig. 1 and described.

The vent of easing ll. through pipe 1) is shown as being controlled by a diaphragm p (l, which is forced outward by air-pressure in riser R, thus holding the outlet of pipe j) closed until the air-pressure in the system is destroyed by the opening of a sprinkler S. It will be observed that the pipe 1) in this form of the valve apparatus enters the supply-main M between the valve S V and. the source of water-supply, and that it is provided with a way-cock w c, as in Fig. 1, and it is due to state that this location of the entrance of pipe 1) into the main M is an cssentialfeature of this apparatus.

The valves for controlling the pipes 23 and 1) allow of the use of this apparatus, like the one shown in Fig. 1 and described, in a wet system or a dry-pipe system, and the alarm apparatus shown in Fig. 1 and described can be used with the apparatus shown in this figure.

In Fig. 1 the valve (l tis shown enlarged and consists of a pivoted or hinged valve in the main-riser and is provided with connectionsj, that normally rest in contact with the springs, which is insulated on block i. Electric connections are attached to s and j, and by separating the parts .9 and an electric circuit is interrupted and an alarm given by any desired and well-known apparatus for indicating and sounding alarms. It is obvious that the motion derived by the piecej, so attached to the valve a t as to move with it, can be made to start a wound-up train or otherwise operate an alarm that is not electrical.

The advantage of an alarm operated by a valve that is raised only by water llowing into a system and cannot move when changes take place outside of the system is great. The ordinary alarm apparatus for use with sprinklers, and which depends for its operation on a lowering of pressure in the pipes when the sprinkler opens, it used with a wet system and attached to the ever-fluctuating pressure of a city water-supply, has been found to be wholly unreliable.

lly the connections fixed to the valve (t w the lowering of: pressure in the city supply will not disturb the alarm, and by the employmcnt of the valve r! 1: the use of the gage G with electrical connections is made more effective for denoting when a sprinkler has opened, and by employing two independent meansforproducinga signal when a sprinkler opens the certainty of obtaining alarms is enhanced. It is obvious that the connections for the valve (1. r can be made within the riser It and wires enter the said pipe, or the said connections can be upon the eXterior,as shown in Fig 1.
