display-room, whether accomplished by a reflecting or refracting medium.

What I claim as my invention is—

1. A show-window comprising two sections, a vertical plain-glass section and above it a vertical prismatic-glass section, and having a display-room arranged therein, said display-room having a roof of the kind described, whereby rays of light entering the upper section of said show-window will be reflected downwardly to join with the horizontal rays from the lower section upon the display in the show-window, as described.

2. In a show-window, a display-room extending part way only to the top of the window, having a roof of the kind described, whereby rays of light passing in through the top of the window will be received upon said roof and deflected downward to join with the horizontal rays coming from the lower part of said window, as described.

3. in a show-window, the display-room above described, having a transparent ceiling and a series of independent pivoted mirrors suitably supported above said ceiling, said ceiling being below the top of the window, whereby rays of light passing through the upper part of the window and above said ceiling will be deflected downward upon the display of the display-room, as described.

4. A show-window comprising a prismatic-glass section and a plain-glass section, a display-room approximating in height the height of said plain-glass section, a transparent ceiling to said display-room, and a series of independent deflecting-mirrors located above said transparent ceiling and in line with rays of light passing inward through said prismatic section, as set forth.

5. The show-window above described having a prismatic section above and a plain-glass section below, a display-room approximating in height the height of said plain-glass section, a transparent ceiling to said display-room, a series of independently-adjustable deflecting-mirrors located above said transparent ceiling and adapted to deflect rays of light received from said prismatic section downward upon said display in said display-chamber, as set forth.

6. A display-room ceiling comprising a

frame within which is set a transparent plate of glass or the like, in combination with a series of independently-adjustable mirrors situated above said plate, and means whereby each mirror is independently adjusted.

7. In a show-room illuminator, a series of mirrors adapted to be adjusted about a longitudinal axis, and means whereby they are so adjusted, said means comprising a clamp mechanism located at each end of each mirror and mounted on an axis parallel with the length of each mirror, and means whereby said clamp is held in place, as described.

8. A deflecting-frame and means whereby said frame is supported to adjust the line of its front and rear edges comprising sleeves attached to extensible socket devices situated on the corners of said frame and adapted to slide vertically on rods, and means whereby the said sleeves may be clamped to the said rods, as set forth.

9. A deflecting-frame, a series of independently-adjustable axial mirrors, and means whereby the height of each mirror may be independently adjusted, as described.

10. A deflecting-frame having a plurality of sleeves hinged thereto on opposite edges, in combination with a plurality of supporting-rods each adapted to slide through one of said sleeves, and means such as a set-screw for clamping each sleeve to its rod whereby the angle at which said frame will lie to the horizontal may be determined by the distance of the rods on one side of the frame from those on the other side, as described.

11. In a show-window comprising two sections, a lower vertical plain-glass section and above it a vertical prismatic-glass section, a show-room as described, in combination with a reflector adapted to be raised and lowered, whereby light entering the upper section of said show-window will be reflected adjustably downward to join with light coming through the lower section of said window.

In testimony whereof I hereunto set my name this 28th day of April, 1903.
