Improvements in Windows.
I, WILLIAM STORRS MACHARG, of No. 1410 Marquette Building, Chicago, County
of Cook, State of Illinois, United States of America, Gentleman, do hereby declare
the nature of my invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
My invention relates to improvements in windows and has for its object to pro-
vide a controllable window for reflecting or refracting or diffusing the light. My
invention is illustrated in the accompanying drawings wherein
Figure 1 shows a face view of a window embodying my invention;
Figure 2 is a section through the same;
Figure 3 is a section on line 3-3 Figure 1.

Figure 4 is an enlarged view in part section, showing the manner of connecting
the window sash with the frame;
Figure 5 is a section through a modified form of window embodying my
invention.
Like letters refer to like parts throughout the several figures.
A
I have illustrated my invention in connection with windows wherein prismatic
glass is used to diffuse or distribute the light throughout the room, or so as to
direct it toward the part of the room away from the opening through which the
light passes. It is of course evident that I may use either reflecting or refracting
glass, or a glass which both reflects and refracts the light if desired. In the draw-
ings, I have simply endeavoured to show one form of my device so that its applica-
tion may be easily understood, but of course I do not wish to be understood as
limiting myself in any manner to this construction. My device is particularly
applicable to windows which are set in a considerable distance from the outer edge
of the wall, but, of course, it may be applied to any description of window.
illustrated in the drawings, a window sash A is movably suspended from a fixed
point in any desirable manner, as by the hinges A', so that it may be moved to an
angular position. The prismatic or other glass is connected with this frame. I-
prefer to connect the glass with this frame so that it may be moved therealong as
shown in Figures 1 and 2. The glass which may be of any description, and which
is shown in the drawings as consisting of the series of prismatic lenses A, is
placed in the frame or sash B. Said frame or sash is pivotally connected with the
sliding blocks B in any desired manner as by means of the pivot pins 1 These
sliding blocks B are free to move up and down in guides B in the frame or sash B.
The frame or sash proper is of such size that it may be rotated about its pivots so
that its angular position may be varied. A second block C may also be used so
as to fasten the sash or frame B in position, thereby preventing its rotation. In
this event, the block C is provided with the notch or cut away portion C and the
frame or sash B is provided with the movable arm controlled by the thumb
piece C, the frame or sash being locked in position by moving the piece C³ into
the notch CL I prefer to provide the sash or frame B with weights D, said weights
being connected to the sliding blocks B. I provide the window sash A with some
suitable device by which it may be held in any desired angular position. As shown
in the drawings, this device consists of the strap or piece A1. The window sash A
may be completely filled with glass, if desired as shown in Figure 5, in which
event the light will be completely and easily controlled by changing the position

the ordinary window sashes D¹ D. The frame or sash B is preferably provided
with a holding device, as for example the frictional contact of the pivot pins, by
which it may be held in any desired position at an angle with the window sash A.
The use and operation of my invention are as follows:
When a window is deeply set in the wall as shown in Figure 2, the light coming
from an angle from the sky, will only strike a small portion of the lower part of
the window and hence if such window is filled with prismatic glass or the like, the
larger part or at least a part of this glass will not be utilized. By making the pris-
matic or other glass movable as by connecting it with the window sash A, it can be
moved out at an angle so as to be brought in the path of these oblique rays of light.
When the prismatic or other glass is placed in the frame or sash B so that it is
movable with relation to the window sash A, the light can be thrown to any part
of the room, as for example, upon a desk or table by moving the same or sashi B,
any desired adjustment being easily and quickly made. It will be seen that this
frame has two movements, one along the window sash A and the other at an angle
to said window sash. The window sash A can be moved back within the window
frame at night so as to allow the shutters to be closed, when it is used in connection
with windows having such shutters. It will also be seen that the glass can ba
adjusted so as to receive the light at the best possible angle to obtain the maximum
results and that the point of application of light can be varied at will.
pivoting of the frame or sash B to the window sash A allows the frame B to be
rotated about its pivotal connection so that it can be easily and quickly cleaned.
The
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
A controllable window for reflecting or refracting or diffusing the light, sub-
stantially as herein set forth.
