ATENT l EEICEo IMPROVEMENT IN FIRE-PROOF SHUTTERS.
Specification forming part of Letters Patent No. 140,839, dated July 15, 1873; application led June 21, 1873.
To all whom it may concern: p
Be it known that I, ISAAC S. METTLEE, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Fire-Shield for Doors and Windows, of which the following is a specication: i
The object of this invention is to protect buildings from fire; and it consists in a metallic shield or protector for Covering the windows and doors of a building constructed substantially as hereinafter described.
In the accompanying drawing, Figure 1 is a front outsideview ci' the shield. Fig. 2 is a side view. Fig. 3 is avertical section taken on the line :v no of Fig. l. Fig. 4is a modification.
Similar letters of reference indicate correspondin g parts.
This shield consists of a frame, A, of sheet orthin metal, which is placed in contact with the wall of the building. Back of this'frame, and sunken in the wall, or received in the window or door opening on each side is a weight-tube, B. Attached to each side of the frame (outside) is a perforated casing, C, connected together at the top by the cornice D and the frieze-plate E. F represents sliding sections which form the front of the shield.
These sections are formed of an inner and an outer sheet or plate of metal secured together at top and bottom by plates g g, a proper distance from each other, with or without an intervenin g sheet or plate of corrugated metal, h. I represents the openings in the Side casings C, and the sections F are arranged in relation to these openings, so that there will be unobstructed openings or channels through the corrugations or section from one side of the window to the other to allow a free circulation ofair. The corrugated plate h strengthens the sections and renders them stiff and serviceable. These sections (of which there may be more or less in number) are confined in grooves on the inner sides of the casings C, each section having grooves of its own. Across the top of the shield, beneath the cap of the cornice, is a shaft having a pulley, J,
`near each end, over which are cords or chains K,
one end of which cords or chains is attached to the lower section and the other end to the weight L, as seen in Fig. 3. m is an inwardly-projecting flange, which extends from each section into the groove of the adjacent section, so that when the lower sectionis raised its top Strikes the iiange of the next above and raises that, and so on, each section being raised by the section below, so that all may be securely packed beneath the cornice and back of the frieze-plate E. The weights L are intended to balance the sections in that position. In the modication, Fig. 4., the sections are raised by separate cords, but the result is substantially the same. The sections may be formed in the manner described, and be hinged together and be raised and lowered by means of ahexagonal cylinder placed beneath the cornice; but I prefer the arrangement shown.
At night, or whenever there is danger from fire from the burning of adjacent buildings, the shield is drawn down, thus forming a perfeet lire-protector to the window, or door.
This shield is not intended as a safe-guard against burglars, but it may be fastened down to the sill, so as to serve for that purpose, if desired. Y
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A door or window shield or protector with openings I, by means of which a free circulation of air, laterally, is secured through the protector, substantially as shown and described. l
2. A window or door protector constructed of sections formed of two or more sheets or plates of metal which are arranged to be raised and lowered vertically for the purpose described.
3. A window or door protector consisting of two or more sections having horizontal open# ing for the passage of air, whether such sections have a corrugated plate intervening or
