Having thus described my invention, I claim as
new and desire to secure by Letters Patent— 1. Prism-plates provided with flat marginal surfaces in their prism-faces, and grooves in said prism-faces between the flat marginal surfaces and adjacent prisms, and a channel-plate the side members of which enter grooves in adjacent prism-plates, said channel-plate being adapted to be cemented to the prism-plates, as set forth. 2. As an improved article of manufacture, a prism-plate having a flat marginal surface at its prism-face, and grooves in said prism-face at opposite sides and located between the flat marginal surfaces and adjacent prisms, said plate being also provided with flanges upon its smooth face at opposite edges, which flanges are at right angles to the groove and incline from their outer edges downward to meet the plain smooth face of the panel, as described. 3. The combination with prism-plates having a flat marginal surface at their prism-faces, and grooves in said prism-faces |
adjacent to the flat marginal surfaces, the said plates being also
provided with tapering edges and with flanges upon their smooth faces at
opposite edges, inclining from said edges downward to the smooth faces
of the plates, which flanges are at right angles to the said grooves,
of inverted-T beams, the webs of which
extend upward between the flanged edges of opposing prism-plates, a
packing within the spaces between the edges of the prism-plates and
the webs of the beams, extending to the tops of said webs and to an
engagement with said flanges, a channel-plate, the side members of which
enter the grooves in adjacent prism-plates, and packing in the spaces
between the grooved edges of the prism-plates, which packing extends to
the channel-plates, as set forth. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
