FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 253,720, dated February 14, 1882.

I Application filed December5,188i. (No model.)

To all whom it may concern:

Be it known that 1, ISIDOR KITSEE, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Fire-Extinguishers, of which the following is a specification.

My invention relates tothat class of fire-extinguishers that are brought into operation automatically during an incipient fire by melting of fusible connections.

The object of my invention is to cause water to be led through pipes located in various parts of a building, and to be ejected through noz zles or perforations on said pipes, when a governing-valve that arrests the flow from the main water-supply is opened; and my invention consists in the peculiar construction and operation of improved devices that control and actuate the several operative parts.

Referring to the drawings that accompany this specification, in which similar letters of reference indicate like parts 011 each figure, Figure 1 represents an ordinary water-supply pipe with my improved device attached. Fig. 2 represents a piece of pipe with branch pipe attached. Fig. 3 represents a transverse section of a house supplied with my improved fire-extinguisher. Fig. 4 represents part of a vided with a disk or cap, 0.

transverse section of a house supplied with my improved device, showing the manner of controlling the fiow of water on each story by means of se'para te valves on each conduitpipe.

a is an ordinary water-pipe. In Fig. I it is shown as provided with perforations b; but in lieu of or in combination with the perforations it may have open eduction ends, as shown at b, Fig. 2, which should be screw-threaded to admit of coupling hose or nozzles thereto. This pipe is .led through the several rooms of a building in any required direction.

0 is a cylinder, in which is a piston-rod pro- When this piston-rod is held downward within the cylinder, as shown in Fig.1, it closes a valve of any suitable construction which controls the passage of water from the main supply.

61 is a spiral spring coiled around the cylinder 0 and pressing upward against the disk 0.

g is a-fusible wire or cord which is passed through staples or over pegs 9, through the various floors of a building, and finally through an eye or staple, 9 on the conduit-pipe near the cylinder 0, and at this point the fusible wire or cord 9 is connected with a fusible trussbrace, E, which holds down the cap 0 and retains thespring (Z retracted, asplainly shown in Fig. 1.

When the temperature rises to a given degree in any part of the building through which the fusible connection 9 passes the said oonf nection is ruptured and the tension of the brace E on the cap 0 is withdrawmreleasing the springd and opening the valve. The water immediately flows from the supply through the conduit-pipes a and is ejected from the perforations b or eduction ends b.

Fig. 3 represents the manner in which the conduit-pipes b and fusible connections 9 are arranged within the chambers O O O O of a building. The supply in this illustration is represented as being drawn from an ordinary water-main; but it may be secured from a reservoir' or cistern where a system of water-service is not established.

The valve, and its operative parts are shown in the drawings as located in the basement of a building; but one or more of said devices can be placed in any desired location.

It is manifest that when the brace E is ruptured the water fed from the main supply would flow through all the pipes and be discharged from all the eduction-openings, while it is desirable, in order to secure the best results, that it should only be ejected in the story of the building where there is a fire. In order to secure this object I control the discharge on each floor by a separate valve held closed by a fusible brace, E, and to this end a vertical standpipe, A, is located the full height of the building, having lateral branches a. on each story. These lateral branches have each a separate and independent valve kept closed by a fusible brace, E. When the fusiblewire g is melted it will cause the main valve that shuts oft the water-feed to open, and the water will at once tlow through the stand-pipe A, but will only pass into the lateral pipes to that have had their respective valves opened by melting of the brace E that controls them.

Having now fully described my invention, what I claim is- 1. In an automatic fire-extinguisher, the watical stand-pipe A, having lateral perforated fer-conduit pipe a, provided with perforations branches (4, each provided with a valve closed b, in combination with a valve-closing fusible with a fusible brace, E, in combination with brace, E, and branch fusible wires 9, substanfusible wires g and fusible valve-closing brace 5 tially as described. E, substantially as described.
