DOOR.
SPECIFICATION forming part of Letters Patent No. 443,541, dated December 30, 1890.
Application tiled March 4, 1890. Serial No. 342,670. (No model.)
To @ZZ whom, it may concern.-
Be it known that I, CHARLES E. RICHARD- SON, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, haveinvented a certain new and useful Improvement in Doors, of which the following is a full, clear, and exact description.
The object of this invention is to provide a double paneled sheet-metal fire-proof door forA dwelling-houses and the like buildings, which is of simple, economical, and durable construction.
The invention consists of an interior door composed of a frame or core of wood or equivalent material, an outer covering or casing comprising two like or similar sections of sheet metal entirely concealing the wooden frame or core, and means for securing said metal sections to the wooden frame or core, substantially as hereinafter more particularly set forth and claimed.
In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure l is an elevation. ,'Fig. 2 is a vertical section taken in the plane of line m, Fig. l. Fig. 3 is an elevation of the wooden frame or core. Fig. et is a detail showing the preferred manner in which the metal sections are secured to the fra-me or core. Fig. 5 is an edge view of the finished door, and Fig. 6 is an edge view of the wooden frame or core.
A door constructed in accordance with my invention consists of a wooden frame or core, which, as herein shown, is composed of the uprights a a, end pieces b b, and a central cross-piece c, all of which are suitably jointed, (see Fig. 3,) and upon this frame or core is secured the exterior covering or casing, which consists of two like or similar sections CZ d, of sheet metal, preferably steel, said sections being stamped, rolled, or pressed into any desired design and configuration of paneling d. After these metal sections d are thus stamped, rolled, or pressed into the desired shape the edges thereof are bent at right angles to form flanges e, which serve to conceal the edges of the wooden frame, and also aid in securing the metal sections to the frame or core. One of these met-al sections d is placed upon each side of the frame or core, and the flanges e of said sections are fitted over and upon the sides and ends of the frame and are fastened thereto by means of screws or nails.
In Fig. et of the drawings I have shown the preferred form of fastening for securing the metal sections upon the frame or core, which is as follows: The uprights a a and end pieces b b of the wooden frame or core are provided on their outer faces with grooves f, into which the Iianges e of the metal sections are forced or bent, as at g, and in these grooves and upon the anges thus bent or forced therein I secure metal strips h, which are provided at suitable intervals with holes or openings to receive screws t' or other fastening devices, and these metal strips h are of such size and shape as to fit snugly into the grooves f and be flush with the edges of the door.
The door thus constructed may be painted or otherwise iinished, so as to have the appearance of an ordinary Wooden door.
I have herein shown the metal sections d as constructed of a single piece of sheet metal 5 but I wish to be understood as not limiting my invent-ion to this exact construction, as each section may be constructed of as many smaller sections as may be desired.
The wooden frame or core not only serves to stiften and strengthen the door, but also serves to prevent it from warping v--a difficulty heretofore experienced in doors made entirely of sheet metal.
I am aware that it is not new to make a door of an interior core of wood and an outer covering or casing of sheet metal, entirely concealing the wooden frame or core.
That I claim is l. A reproof door for dwellings and the like, composed of an interior wooden frame or core, two like or similar sections of sheet metal stamped, rolled, or pressed to represent paneling and provided with edge iianges, said metal sections being placed upon opposite sides of said wooden frame or core With their iianges litting over and upon the edges thereof, and a metal strip 7L and screws t' for securing said iianges in place, substantially as described.
2. A lire-proof door for dwellings and the like, composed of a wooden frame or core provided with grooves f in its edges, two like or similar sections of sheet metal placed upon IOO opposite sides of said core or freine, and han in g flanges e, which are adapted to be bent or forced into the said grooves, and fastening devices for said flanges, Substanielly as dcscribed.
3. A Fire-proof door fer dwellings and the like, composed of ai wooden frame or core provided with grooves j" in its edges, two like or Similar sections of Sheet metal placed upon opposite sides of said core or frame, and having ilanges e, which are adapted Lo be bent or forced into the seid grooves, metal strips placed in said grooves :1nd upon the flanges to Secure the saine in pince, and suitable fastening,r devices for Suid strips, substan tinlly 15 CHAR ILES E.
