AU'EGBJIA'IIC SPBINKLER SYSTEM.

Application filed November 25; 1513..

' Specification of Letters Patent.

Fntented ami o, isle.

Serial No. 662,347.

To all whom it may concern:

lie it known that l. 'lYiniUs J. ST \Nl-HE- rice. citizen of the United States, residing at mago, in the county of Cool; and State of l inois, have invented certain new and t h ll 0. e ul Improvements in i'liuton'iatic Sprinkle S ansjot' which the following a specification.

This invention relates to certain iprovements in automatic sprinHer-systems and the particular improvements which constitute the subject matter upon which I claim a patent. relate to the means for dischargting, the water'into a room where the system is installed and to the operation of a, snitable alarm device connected with such discharge and operated by the flow of water through the discharge device.

More specifically, in invent-ion relates to a discharge nozzle having eittensiole or telescopic functions. the means for supp0rti'ng said nozzle when in inoperative position, and 21V rotatable alarm operating device tion.

Some of the objects attained by the said improi einents are certainty in the operation of the sgrinlzler when the conditions which call for its use are pres nt; the concealing of the apparatus until it. is needed in oporation, and the thorough distribution of the system of w ster discharged from the nozzle through a editable sprinkler head.

in the accompanying drawings. l have ntion of in}! inv tion and improvements in the followin views:--

Figure 1 shows partly in .I'E l nozzle in oi ierative pos tion and l'filll'lun when erected in the ceiling of an o notion of t room; Fig. 2 is a cross matic alarm operating device with its odjacent' pipe sect ons; Fin. 3 a longitudinal section of a portion the t lcscoping; in n hers of the nozzle and Fig. is a perspe tive View of a cap or closure which serves to conceal the nozzle when not in use and which is automation j opened w en water is flowing through the noznle Referring to the details of he drawin represents generally" a castnictal which connected. thereto and con1niuni-- eating therewith pipe extensions 5*, If", which are placed. respectively at' the upper lower OD1ODS of the casing serve as conductors for *ater to and from the casing. This casing is supplied with a cover 5" on one side which is i'einovahly connected themwith by screws Arranged transverseh. "f the casing" having suitable hearings in the rear wall and cover thereof is a spindle 8 on which is'rotatably mounted a wheel '9,

to the periphery of which are pivotaily mounted a series of curved blades 9 the pivoted ends of which are formed with shoulders 9 which limit the outward movement the blades as clearly indicated in Fitz.

gainst the wheel in the opposite direction.

The spindle 8 projects tln'oughthc casingcover 5 and has mounted thereon a curved oawl 1.0 which rotates with the spindle. At

one side of and near the lower portion'of 2. while permitting the blades to fold a the casing is a stud screw 1 on which is pivotslly mounted .a two-arm lever 11, one arm of which 11 in the path of rotation otthe pawl. 10, and the other arm 11 of which is supplied witha hammer 11 at its extremity which is so placed asto be brought into intermittent contact with a bell l2 se cm to a pipe Y which extends fromthe branch 5' of the casing The upper end of the pipe 7 is screwed "ring; and twisted blades 16, 7. so arranged to eliect the rotation of this member as the water discharged through the coupling 1%: impinges thereon.

The device above described is preferably iii-ranged snd'suitably supported between the joists Q3 and the ceiling and floor which form the usual construction in buildings oi the class to which my invention is applicw lole.

A l and 25 representrespectively the lath and plaster attached to the ioists 23 in the usual manner. "he lath and plaster have been cut away, in part to provide a suitable opening for an annular socket plate 18' which set into the opening and supported hv the lathe. tnz'ewith a collar 18 on. the upper face of This late has connected I which are a series of beveled lugs 19 formed with the overhanging-flanges which serve to engage the lower flan e of the socket plate 18 and thus removab y attach the col-v lar 19 to said plate. Connected with the collar 19, by a huge 20, is a cover 21 which is provided with a spring latch 22 so formed and arranged as to engage the collar 19 and holdthe cover in closed osition until the latter is subjected to sufficient pressure from above to overcome the tension of said latch.-

From the construction above described,

assuming that the nozzle is housed between the joists 23 and above the ceiling connected with said joists, water through the casing wi force the blades 9 outwardly and thereby rotate the spindle I 8 with its pawl whichwill produce an intermittent movement in the leverll and a.

consequent pounding of the hammer 11 against the bell 12*. Pressure of the water flowing through the pipe connection 5 and impingin on the shoulders atthe upper ends-of t e pipes 13, 13*, and the members 16, 17, will cause said pipes to move downwardly their full limit, thus bringing'the' discharge end .of the nozzle to a pos tion Within the room where the water will be distributed most efi'ectively by the rapidly rotating members 16,17. The same water pressure, it will be understood, will be sufiicient to force the cover 21' to its open position as shown, thus permitting the extensionof the sprinkler head proper to its full operative position. In order to facilitate the free rotative movement of the collar 14 with its yoke 15, I provide ball bearings 26 arranged as shown in- Fig. 3.

i I have not shown nor describedany means for automatically permitting the water to 1 flow through the nozzle described because same forms no part of this invention, which 1.

' 4. In a sprinkler system, an extensible sectional-nozzle arranged above the ceiling of a room, a sprinkler head mounted on said nozzle, means for supporting said nozzle withln the ceillng, saldmeans adapted to release the nozzle when subjected to, the pressure of water flowing from the nozzle. 5. In-a sprinkler system, an extensible sectional nozzle arranged above the ceiling of a room, a sprinkler head on said nozzle, a collar set in the ceiling-and a cover connected with said collar and adaptedv to concoal the nozzle from view and to release'it flowing through the nozzle.

In ajsprinkler system, a nozzle formed in sections telescopically arranged, a sprinwhen subjected to the pressure of water kler-head rotatably mounted on the discharge wall, said means adapted to release and unend oi said nozzle, means for supporting and concealing said nozzle within a hollow cover said nozzle when water flows through the latter.

.In testimony whereof I aflix my signature in the presence of two witnesses.
