Mounting Hexagonal Prism Lights for Windows.
I, JOIN MEIGGS EWEN, of No. 1129 The Rookery, Chicago, County of Cook,
State of Illinois, United States of America, Mechanical Engineer, 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:
1
My invention relates to improvements in mounting tile sections, particularly
Frismatic tile and prismatic lights.
I have illustrated it in connection with prism lights of the hexagonal form; but
I do not wish to be limited to the particular details here shown, as they may be
considerably modified without departing from the spirit of my invention. My
invention is simply illustrated by the particular devices shown.
Figure 1 is a plan view of a portion of the surrounding frame and the warps.
Figure 2 is a view of the same with some hexagonal sections of prism lights
inserted in position, with some ties; and
Figure 3 is a complete prism plate.
Figure 4 is a plan view, and
Figure 5 is an elevation of the ties.
Figure 6 is a cross-section on the line 6-6 of Fig. 1.
Like parts are indicated by the same letter in all the figures.
A A are the elements of a preferably steel binding-frame for the complete plate.
In this case the prism light sections are brought against this steel frame, there
being no intervening warps, ties or other ribbon-like parts, as I have heretofore
used in many instances. These frame pieces A A are secured at the corners and
may be soldered together. B B are the warps secured or soldered to the lower
frame strip, and they may be straight, as indicated in Figure 1, being adapted to
he formed into the zigzag shape required for the hexagons, or in some instances
they may be in the zigzag shape which they finally assume, as indicated in Figure 3.
In any event, they must be properly separated at points where they are secured
to the frame. Assuming that they are straight strips or ribbons, the tile
sections C C are placed in position, the strips being bent over so as to form a sort
of binding for the same, and the sections D D are then placed in position, where-
upon the warps B B assume the shape indicated in Figure 2. The ties E E.may
now be dropped in position, the keys F F receiving between them the warps and
the adjacent corners of the tile sections or prism lights. The small side sections G
having previously been put in place, the outer warps are brought against the side
frame pieces or strips, and here they should be soldered or secured to such frame strips.
This process is now continued, the sections H H being inserted so that when the latter
is finished as indicated in Figure 3, a complete prism plate is formed in which
there is a net with a surrounding binding-frame and prism lights secured in such
net and binding-frame. Each light or section of a light has a complete metallic
binding, and is held at its corners by keys which engage its opposite sides, except
an occasional outer section, where if necessary the prism light section can be
easily secured in any desired manner. Of course this net can be of any desired

page_text: strength, the warps and ties being of any desired thickness, and the frame like-
wise may be of any desired thickness. The net strips and the surrounding frame
are preferably of the same thickness, measured in lines perpendicular to the plane
of the completed plate, and this thickness coincides preferably with the thickness
of the body portion of the prism lights, so that the finished product will furnish
one continuous smooth surface on the plane side.
The product may now be treated in any desired manner to make it wind or
water-tight, as for example, it may be subjected to the electro-glazing process if
necessary to protect it in the uses to which it is to be put. If the frame is made of
steel, it should be copper-plated if intended to be exposed to the electrolytic bath.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A plate composed of a series of sections, a surrounding frame, a series of zigzag
strips extending across the frame in one direction and separated from each other
by intervening sections, and a series of short transverse strips between the sections
and connecting the zigzag strips at their points of nearest approach, the whole
securely tightened together.
Dated this 13th day of July 1897.
