ooo ooo 542--- ooo- .ozao-l Lkj UNITED IMPROVEMENT IN FIREPROOF SHUTTERS.
. Specification forming part of Letters Patent No. 142,563, dated Sept-amber 9, 1873; application lcd July 15, 1873. l
This invention has for its object to so eon struct iron doors and outside shutters in a eellular forni as to combine lightness and economy of cost with efficiency to resist the transmission of external heat, and to afford a ventilation for the room closed by them; and it consists in a t'ranie of channel-iron having secured to it an outer and inner covering of sheet-iron divided into cells by vertical channel-bars, which, as well as the coveringplates, are perforated, which perforations are on varying planes, to prevent the passage of llame.
Figure l shows a double-Win ged shutter, the outer plate of each halt' being partially broken away to show the internal construction. Fig. 2 is a cross-section at a: as.
In the drawing, A represents the frame of the shutter, made of channel-iron, as affording great stiffness with ainininiunl of weight and cost. The frame is divided by vertical channelbars A', riveted at top and bottom. B isthe inner covering of sheet-metal plates, and B is an outer covering of the saine material, both riveted to the main traine.
a are sets ot' apertures in the frame A, bars A', and coveringplates, no two sets being on the saine horizontal plane, so as to preclude the passage of iaine, While they serve not only to ventilate the building during the night and days when it is closed, but when the outer plates are heated from an adjacent coniagration a strong draft of air is established between the plates, keeping the inner one cool, and thus preventing dainage to the interior of the protected building or its contents. For this purpose the bottoni bars of the frames are perforated, as shown in Fig. 1, and for the purpose of allowing water to dow oli' which may accumulate therein.
What I clainl as my invention, and desire to secure by Letters Patent, is-
l. A double-walled iron shutter divided into cells by vertical channel-bars, substantially as herein described and shown. l
2. In a cellular double-walled shutter, constructed substantially as herein described, the pertbrations a in the bottom bar, the vertical channel-bars, and the covering-plates, when arranged in dii'erent horizontal planes, substantially as described.
