' Suitably supported above'the window and;

door openings areypipes S through which water is supplied to the sprinklers either from a reservoir (notshown) upon theroof of the house, or, through any other means, such as direct connection through; automatic valVBS' with the water system.

town or municipal plant, or rainswater; caught from the roof, and, when desired,thej

necessary, au ticor ifioat valves anaemployed to regulate the depth oft-he water therein. i

Figures 2, 4 and 5, the win mediate the ends of the jambs 22, the purpose of Which will presently appear.

A header 25 closes the upper ends of the compartments 20 and the chamber 23 and is provided with openings 26 and 27 which establish communcation between these compartments and chamber withan upper coinpartment or chamber 28 formed above the window frame proper and provided with a header 28. The outer face 29 of this window frame is providedwith an opening 30, the purpose of which will presently appear, while the inner face is formed by the sheet 31 of perforated celluloid or other fusible material, the pipe 15 connected with the sprinkler system being extended into the chamber 28 from above the latter and carrying the globular sprinkler head 16. A fusible plug 17 between the end of the pipe 15 and the sprinkler head normally prevents the passage of water from said pipe to the sprinkler head.

In' the interior door construction, the frame 13 is provided, as shownin Figures 3, 6 and 7, with a header 33 which, with the subheader 32, provides a chamber 34. Openings 35, formed in the door jambs between the header 33 and sub-header 32 are directed toward the wall or partition in which the frame 13' is supported. The front and rear of the chamber 34 are closed by perforated sheets of celluloid or other fusible material. A sprinkler head16', connected by a pipe 15 to the pipe S, is mounted in the chamber 34:.

' In the case of a doorway in an outer wall of 35 the building, only the inner side of the chamber 34 is closed bya perforated fusible sheet and the other side of the chamber is closed by a plate, such as the plate 29, shown in Figure 8, having an opening 30. In freezing weatherthe sprinkler heads 16 and 16 may be isolated from the water supply pipe'S by a valve (not shown). V

Where so desired, a sprinkler 16 may be mounted centrally of the room and within the support 38 which, in turn, supports the sheet metal member 39 constituting the upper supporting fixture of an electric chandelier 40, or

the like, the same being provided with perfo ration 11 through whi'chwater will be projected from the automatic sprinkler 16' when the plug 17 is fused by excessive heat.

' Although one" form of sprinkler head'is here shown, it will be apparent that any type of automatic heat released sprinkler head may be employed without departing from the spirit of the present invention.

' In operation, the reservoir (not shown) supplies water to the various sprinklers throughout the entire system, and should draperies, or the like, become ignited, the heat therefrom at any of the windows will cause the celluloid sheet31 to fuse, and such heat will' also fuse the plug 17 so that water will be projected into the chamber 28 and through 66 the various openings therein downwardly or partitions of the building may each have a concrete base and all the walls may be constructed of a fire-resisting material, in which event, the only inflammable materials employed would be those in the. door and window frames. Thus fire adjacent the doors or windows will ignite the ignitible sheets 36 and 37 and fuse the plug 17 so that water may flow through the sprinklers;

I claim 1. In a building having door and window openings in its walls and door openings in its partitions, frames in said door and window openings each having a'chamber at its upper portion, a sprinkler head of the heat responsive type in each of said chambers, means for supplying a fire-extinguishing agent to said sprinkler heads, and panels closing the sides of said chambers, one of the panels of each of said chambers being formed of inflammable material and being so positioned relatively to said sprinkler heads that their burning will release said heads.

2. Aframe for an opening in a wall or partition of a building having a hollow portion behind each of its jambs and a chamber above its head communicating with said hollow ortions, aisprin'kler head in said chamber aving an inlet for connection to a fire-extinguishing-agent supply means, a fusible lug in said inlet, and a perforated anel of inflammable material closing saidc amberand so positioned relatively to said sprinkler head that its burning will fuse said plug.

3. A frame for an opening in a wall or partition of a building comprising a head, a pair ofjambs, and a sub head between said j ambs below said head, said jambs, head and subhead forming a chamber and said jambs having openings therethrough between said head andsub-head, means closing said chamber at one of its sides, a panel of inflammable material closing the other side of said chamber, and a'sprinkler head of the heat responsive type in said chamber, said sprinkler head having means for connection to a fire extinguishing agent supply means and being releasable by the burning of said inflammable panel. l

4. A frame for an opening in a wall of a 12!! building comprising a plurality of hollow pedestals and a chamber above said pedestals, said chamber having passageways in its bottom wall communicating with the interiors of said pedestals and also having passageways in 136 its end Walls, panels closing the sides of said chamber, one of which panels is formed of inflammable material, and a sprinkler head of the heat responsive type in said chamber, said sprinkler head being releasable by the burning of said inflammable panel.

In testimony whereof I have hereunto set my hand.

JOHN P. THURELL.
