UNITED STATES PATENT OFFICE.
LUKE N. STEELE, OF GHICAGO,ILLINOIS.
IMPROVEMENT IN METALLIC SHUTTERS.
Specification forming part ofLetters Patent No. 157,463, dated December 8, 1874; application filed September 17, 1874.
To all whom it may concern:
Be it known that I, LUKE N. STEELE, of Chicago, Oook county, Illinois, have invented a new and useful Improvement in Fire-Proof Shutters, of which the following is a full de scription, reference being had to the accompanying drawings. I
Figure l is a front elevation Fig. 2, a horizontal section; Fig. 3,.a detail. y
The object of my invention is to provide an improved fire-proof shutter for use upon the outside of buildings, and to provide a protec; tion for the window-casing other than that furnished by the shutter. It consists in the use of a double shutter, ventilated in a peculiar manner, and in combining with an iron shutter metal coverings for the casings.
In the drawings, A represents one of my shutters. It is made double, the two parts a b being secured together at the sides, but not across the top and bottom. The outer piece is provided with a number of very narrow longitudinal openings, 0. The most convenient way to make this part b is to make it of sheet metal, cutting in it a series of longitudinal slits. Then the lower edge of each piece dmay be bent outward a little, and the upper edge may be bent inward a little, giving to the shutter the appearance of the blind in common use having movable slats. (See Fig. 3.) Theinside portion of the shutter, a, can also be made of sheet metal, so shaped at the sides that it can be riveted to the outer part, b. 1- place these two portions a little distance from each other-about three inches-leaving an air-space between them. 0 represents a window-sill. 13 represents a covering for the easings of the window or other opening. It is made of sheet metal, and is formed and fitted so as to cover and protect the casing to which its inner edge is secured. The outer edge, 0, extends a little outside of the casing, and is to be bolted to the brick or stone walls of the building. The shutter is to be suitably hinged either to the part B or to the walls of the building.
The outer portion of the shutter, with the circulation of air between the two parts, will keep the inner portion from becoming very hot, and the casings, which are located where the shutter is not double, will be protected by the covering B.
The parts may be made of castiron instead of sheet metal, and will then be less liable to be warped by heat.
What I claim as new is as follows:
1. The shutter consisting of the two parts a I) the outer portion havinga series of longitudinal openings, 0, all constructed substantially as and for the purposes set forth.
2. The shutter A, formed of two parts, a b, and having openings 0, in combination with covering B, with outer edge 6 extending outside of the casing, all as and for the purpose specified.
LUKE N. STEELE.
