' Application filed July 25,1893- Seria1No. ,399. on model.)

To all whom it mag concern:

Be it known that I, HOMER D. KRAMER, a

- citizen of the United States, residing at Pittsburg, in the county of Allegheny, State of. Pennsylvania, have invented certain new and useful Improvements in Fire-Extinguishing Apparatus; and I do declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled! in the art to which it appertains to make and use the same. p

The'invention relates to that. class of ap-,;

I paratus in which a fire extinguishing gas is,-.

stored in. readiness for use in the extinguish, ment of fires.

The present invention has ject the application to buildings or vesselsof' a system of pipes so arranged in. connection with storage tanks charged with liquefied carbonic acid gas, that the gas generated from such storage is, by directedaction, carried to and projected into the section of such building wherefire may be discovered. By means of thecarbonic acid gas in its liquefied condition, and by means of the apparatus, hereinafter fully set forth, it is my purpose to proentering the building apartments I have pro;

vided an,escapement pipe which is so connected with the plant as to carry ofl' into open air any gas which may leak from the storage chambers, and through the valve which establishes communication with the distributing system, thus rendering the escapement of gas into the said distributing system, and thence into the building, impossible.

Again other objects of theinvention have been to'provide the, apartment containing the,

2 plant, with an eduction flue or passage through which, any escaping gas will be drawn, and the apartment ventilated; to profor its main obif vide means 'for furnishing the plant with an auxiliary supply of extinguisher gas from an adjoining plant or portable gas apparatus; to provide a novelconstruction of nozzle combining the functions of an alarm and projecting nozzle; to provide means for determining the amount of liquefied gas in the storage tanks and the pressure of gas in the {:distributing chamber when the plant is in operation.

Furthermore, an important object of the .invention has been to provide means to prevent; the freezing of the liquefied gas, which,

owing to its rapid liberation, causes a very low and rapid reduction in its temperature.

To these ends the invention consists in the novel construction and arrangement of parts, all as hereinafter fully described and specifically defined inrthe claimsu Theinvention is clearly illustrated in the accompanying drawings,:in which- Figure 1, ,is a top or plan view of the fire extinguishing plant or apparatus. Fig. 2, is

a vertical sectional view of a portion of the apparatus disclosing the outlet of the escape pipe, and the gage for determining the quan tity of liquid within the tanks. .Fig. 3, is a view in side elevation. Fig. 4, is aview in end elevation, and in which is shown the con 'nection leading to the outside of the building for the purposes above mentioned. Fig. 5,

is a longitudinal sectional view taken through the combined nozzle andralarm, and also an end view thereof. Fig. 6, is a detail view of one of the valve operating lovers.

The operating portion of the plant is placed preferably within a room located beneath the pavement which is readily accessible from without. and within, and may be provided with a fire proof door opening into. the cellar, and .when the location and surroundings would admit the plant W0l11d;b6 best placed in a special roonrinthe center of cellar.

The base of the apparatus consists of a shallow tank ;1 in which are placed, in a horizontal position, the series of storage tanks 2, whichrest on the-supporting racks 3. There ,arepreferablytwo rows or series. of storage tanks for holding theliquefied gas, and these I are connected to a central chamber 4,- which, from the fact that it aggregates the supply of gas contained in the tanks, is preferably des- I ing a two-way valve, operates to control the passage to the distributing chamber 9 and the escape pipelO. When the valve 8 is turned so as to cut ofi? communication with the distributing chamber, communication is then established between the section of pipe located between the two valves and the escape pipe 10, so that in the event of gas escaping through valve 7 it will be conducted 0E into the outer air, as will be more fully described.

The distributing chamber 9 with which the aggregating chamber communicates is arranged in an upright position or approximately so, and to it connect the series of small pipes 11 on both sides thereof and at various heights throughout its length. Each pipe is.provided with a valve 12 near its con- 1 nection with the distributing chamber, which is operated in unison with the remaining valves 12 and from one point, but may be operated separately when it is desired to direct the gas only into certain apartments and not throughout the entire system.

The entire system of pipes 11 is operated by means of reciprocating bars 13 which are provided with projections 14 which engage the levers 15 by which valves 12 are operated. The bars 13 are movably' supported in the frames 16, and their inner edges are provided with teeth 17 which engage the pinion wheel 18, and in the turning of the pinion one of the rack-bars is caused to move up while the other is carried down. The engagement of the pins or projections 14 with the levers 15 in the movement of the bars 13 causes the said levers to be moved and to open and close their respective valves. The levers 15 are hinged or pivotally connected with the valves 12, as shown in Fig. 6, so. that any one of them may be thrown out of engagement with the pins, but the hinge movement not being in the direction of the swing of the lever in operating the valve, the same remains rigid when in said engagement. The pinion 18 for operating the rack-bars is mounted on ashaft supported by the distributing chamber at about its central point, and is provided with a cross arm or lever 19 for turning the same.

Upon the bars 13 opposite each pin it is the purpose to designate each valve so that in the operation of the plant any apartment or number of apartments may be cut 0E from the flow of extinguisher gas.

water supply pipe.

To the upper end of the distributing chamber are connected pipes 20 which are designed to extend to any desired point, as shown by Fig. 4:, wherein the outlet21 is in the outer face of the building so that gas may be liberated at this point for application through a hose, should fire become exterior; and'further to allow the distributing chamber to be connected with a portable apparatus for augmenting the gas supply. The other pipes 20 are for connection with adjoining plants for furnishing or receiving an additional supply of extinguisher.

As before stated the invention is designed especially for the use of liquefied carbonic acid gas, and as it is of the greatest importance that the condition of the plant should be known by simply a quick inspection at any time, I have provided the distributing chamber with a pressure gage 22, and one of the storage tanks is provided with a tubegage 23 in which the height of the liquid in said tank is shown, and as the storage tanks I connect with the aggregating chamber comgmunication is thereby established between all the tanks, and owing to the condition of the gas and its natural tendency to equalize throughout the entire systemof tanks, an inspection of one tank is an inspection of all.

It will be understood that the communication of the several tanks with the aggregating chamber, is normally open, and by this means there is communication between all the tanks, and hence the gage-tube 23 can be inspected at any time to ascertain the aggregate condition of the tanks.

The tank 1 in which is located the holders of theli'quefied gas, is filled with water or any suitable compound, which will form a surrounding body to the gas tanks to yield heat thereto, or take up the cold produced by the rapid liberation of the gas when the plant is in operation, thus preventing the liquid from freezing.

It is the purpose to supply the water of the tank with a quantity of salt to make a heavy solution of brine, the object of which is to produce a surrounding medium which will not freeze except at a very low degree of temperature. The depth of the solution need not be such as to cover the gas tanks at all times,'but can be increased when it is desired to operate the plant by opening the The tank is provided with a supply pipe 24, a drain pipe 25 and an overflow pipe 26, the last two of which pipes connect with a common drain pipe 27 controlled by valves 28.

On one side of tank 1 is provided a chamber 29 having glass faces through which can be seen the glass tube gage 23 located therein. The chamber 29 preferably does not communicate with the tank 1 and is filled with alcohol or a liquid compound, but may communicate with the tank 1 and be filled with its liquid, if so desired, and the pipe 10 hav- IIO ing its outlet in said chamber 29 and submerged in the body of liquid therein, any leakage of gas from the plant can be readily detected. Thatpart of pipe which extends into the chamber 29 is provided with an upward return bend 30 which carries the pipe above the liquid level and prevents the liquid from entering the entire length of the pipe. From the chamber 29 extends a pipe 31 which terminates at the entrance of the pipe or flue 32 connected with the of the building, which not only causes the ventilation of the entire space in which the plant is located, but carries away any escaping gas directly from the said chamber 29.

The outlets of the distributing pipes 11 are provided with the nozzle shown in Fig. 5 which is so formed as to combine the functions of an alarm and a nozzle. The alarm feature is constructed after the manner of a horn and is provided with a vibrating key 35, or other equivalent means for producing an alarm by the pressure of the gas. Over the end of the outlet is provided a perforated hood 36 of substantially conical form, which receives the gas and deflects it in all directions and particularly toward the Wall through which extends the distributing pipe, thus distributing the gas to such points as would most require it. It has also been found desirable to provide the aggregating chamber 4 with a connection whereby to renew the supply of gas without disturbing the tank connections which would be necessary if the tanks were re-shipped to be again charged. Therefore the connection 33 is provided at one end of the aggregating chamber, which extends through the inclos'lng tank 1, and is provided with a valve 34 in that portion extending within the tank.

On discovery of fire valve Sis operated so as to open way to distributing chamber 9 and to close leakage pipe 10 in the same operation.

Then valve 7 is opened which establishes communication between the aggregating chamher 4 and the distributing chamber admitting gas to the same at a stated pressure, as indicated by gage 22, sufficient to sound an alarm at outlets. The valves of the distributing pipes being closed and their levers engaged, the operation of the pinion wheel 18 opens all the valves and sounds the alarm, principally by the pressure of the gas on theair naturally contained in the pipes. The hinged levers attached to pipes to be further supplied with extinguisher are thrown out of action and the remaining valves are closed by a reverse movement of pinion wheel 18. It will therefore be seen that by the above described construction and arrangement that I have provided astationary, direct acting nonautomatic fire-extinguishing apparatus that is easily and readily operated to a certainty, and one which is always accessible and capable of furnishing an amount of extinguisher adequate for the protection of large chimney structures, as the entire supply can be directed to one outlet pipe, or any number of them, and be augmented by further supply from surrounding plants or portable apparatus.
