SPECIFICATION forming part of Letter Patent No. 595,266, dated December 7, 1897.
Application filed September 27, 1897. Serial No. 653,253. (No model.)
To all whom it may concern:
    Be it known that I, LEWIS H. JORDAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Protected Prism-Light Canopies, of which the following is a specification.
    My invention relates to canopies, and has for its object to provide a canopy with a protecting-screen attached thereto, of which the following is a description, reference being had to the accompanying drawings, wherein—
    Figure 1 is a side view of the canopy with the protecting-screen attached. Fig. 2 shows the canopy and screen folded.
    Like parts are indicated by the same letters in both figures.
    I have shown my invention in connection with prism-light canopies adapted when associated with a window or other aperture entering an apartment to increase the illumination of such apartment. These canopies when in use project at an angle from the window or other aperture, and it is often desirable to have them provided with screens to prevent them from being injured by falling bodies. As illustrated in the drawings, the canopy A is provided on each side with the long braces B and short braces C, both sets of braces being pivotally connected to the canopy and to the window-frame or other part associated with the aperture in connection with which the canopy is used.
    The screen D is connected with the canopy at one end by the pivoted pieces D' and at the other end by the projecting parts D² on
the braces B. These projecting parts are provided with the hooks or angular pieces D4, which are pivoted to the screen. It will be seen that by this construction the screen is folded up against the canopy when the canopy is folded and takes a position some distance from the canopy when the canopy is in use, as shown in Fig. 1.
    I claim—
    1. A folding canopy comprising a canopy proper, two short supporting-arms pivotally connected at the sides of the canopy near one end thereof, two longer supporting-arms pivotally connected to the sides of the canopy between the ends and the middle of said canopy, all of said arms being pivotally connected to a fixed part, said longer arms provided with projecting parts, a screen pivotally connected to said projecting parts, and links at the lower end to movably support the screen, the whole so arranged that the screen and canopy may be folded so as to be out of the way.
    2. The combination of an adjustable prism-plate and a screen mounted thereover, arms connecting the two together movably with reference to each other, and supports for the plate whereby it is held at different angles of inclination, the supports and the arms related in such manner that as the prism-plate moves toward a perpendicular position the screen moves toward the plate and as the plate is moved to an inclined position the screen is moved away from the plate.
