WINDOW AN DDOORAWNING OR SHADE.

SPECIFICATION forming part o f Letters Patent. No. 315,250, dated April '7, 1885.

Application filed July 17, 1ss4. No model.)

To aZZ whom, it may concern;

Be it known that I, GEORGE W. CooK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented anew and useful Improve ment in Window and Door Awnings, of which the following, in connection with the accompanying drawings, is a specification.

The nature of this invention consists inan adjustable folding metallic window or door shade.

The object of the invention is, first, the great durability of such a construction over that of the present canvas awnings; second, the better protection from the suns rays, as the light and heat cannot penetrate the material used in the construction third, it is not liable to take fire from flying sparks or from the burning of an adjacent or opposite building, but on the contrarycan be used as a protection in these latter cases, while the canvas awnings increase thedanger to the buildings to which they are attached; fourth,it is not necessary to remove this shade in the fall, it

can remain a permanent fixture and be used to protect the window from rain, hall, and snow; fifth, as it will not retain or hold water, it does not require any attention during the time of or after a rain; sixth, in addition to its usefulness it can be made very ornamental to buildingswhere inside blinds are used.

Figure l is a perspective View of the entire device as attached to a building and lowered to the full extent; Fig. 2, a front view with the several sections, A, elevated or closed up; Fig. 3, a view from the rear, showing cords, pulleys, and points of attachment with sections A lowered; Fig. 4, sectional view through the center, one-half of the sections elevated, remainder shown in dotted lines; Fig. 5, detail view of one of the sections A; Fig. 6, section on line 6 6 of Fig. 5; Fig. 7, section on line 7 7 of Fig. 4:.

Like letters of reference indicate like parts.

I construct the series of leaves, consisting of the top and sides, A A and A, (shown in Figs. 1 and 5,) out of tin, sheet-iron, or any other metallic substance, commencing with the leaf A and decreasing the size of each leaf in succession, so that they will fold one inside of the other, and in order to strengthen andhold the metal plates in position Ifold in each edge of the several leaves a wire or iron rod, as

shown at a in Figs. 4 and 6. This rod is so folded and inclosed in the edges of each leaf 5,5

or plate as to form a projection the thickness of the 'rod alternately on the two sides and top of each leaf, (shown in Figs. 4 and 4,) so that when the leaves are open or extended, as in Fig. 1, these projections lap each other at the top, and form a lock against a separation of the leaves when the awning is in use. The outer leaf, A, is permanetly attached to the window or door casing, or to the main building, as herein represented, by means of bolts or screws passing through the flange B. This section of the leaves serves as a receptacle for the balance when they are drawn up to their full extent, as in Fig. 2. The leaves are all attached together and hinged by means of the bolts a passing through them; and as the weight of all of the leaves, except A, rests upon the two bolts, I attach the brackets C to the window-casing or other suitable points, by which one end of the bolt is supported, the other end having a bearing upon the fixed section A.

As the device will require painting, in order to prevent the flat surface of the leaves from rubbing against each other, and thereby disfigure the sides, I place the washers a between each leaf at the bottom or tapered ends, and upon the sides, at or near the top of eachsection, I place the bars a which in raising and lowering the sections have a friction-bearing against the side projections, a, of. the next leaf.

In order to raise each section or leaf in turn, commencing at the bottom or lower section, I place the flange a on each-of the two lower corners of this section. (Better shown in Fig.

2.) This flange proj ects sufficient to receive the edges and weight of all the other adjustable sections. Upon the inside of the lower section I place the slugs a a, to which I attach one end of each of the cords D D, and passing the cords over the pulleys d d, which are placed at the top and back corners of the shade or upon the window-casings, as shown in Figs. 3 and 4, I hereby have the means for operating the device. As the metal used for the foundation of this construction will of necessity require to be light, and may require strengthening or stiffening (in addition to the rods a) in the construction of the larger sizes, I would recommend a lining of thin board on the insides of the sides and top of each leaf or section.

In the construction of the shade I do not confine myself to any particular number of the folding leaves, nor to the shape of that part of the leaf forming the top, as they will of necessity be shaped at the top to conform with the top of the windows and doors, many of which are oval and half-round.

What I'claim, and desire to secureby Letters Patent, is-
