I WILLIAM HARRINTON SCRYMGOUR of 50 Lincoln's Inn Fields in the County
of Middlesex Architect do hereby declare the nature of this 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 has for its object to so construct floorings roofs or the like that
they are adapted for lighting purposes. I make at intervals in the floor roof
or the like openings preferably of a conical tapered figure with the larger end
downwards or presented towards the place to be lighted and in at or on the upper
parts or smaller ends of these openings I fix a glass or lens the upper side of which
forms part of the surface of the floor when the Invention is used for a floor. The
openings and the frames or linings may be tubular or of any suitable form as
described or as rendered necessary by the ornamentation or structure with which
they are used I find a convenient and economical mode is to support at intervals
frames or linings corresponding to the openings and then to pour concrete between
them and then put the glasses or lenses in the upper ends of the said frames or
linings but I do not limit myself to this mode of construction.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 shews in plan and section a floor or roof arranged according to my
Invention a are frames or linings which may be round or square or of any suitable
cross section so that they constitute passages through the floor or roof b. On or at
the tops of these linings are placed lenses or glasses c through which and the open-
ings formed by the frames or linings a the light passes from above or from below
or from side to side as the case may be. The floor or roof here shewn is made of
concrete. Figures 2 and 24 shew one made of wood the linings a being made so
that they rest on the rafters d. The linings a are shewn as being made some
angular and some round. In figures 1 and 2 the glasses are shewn as being plain.
In Figure 3 I have shewn them in the form of lenses and the linings are utilized
to support the ornament of the ceiling. Figure 4 shews a mode of construction
without special linings or frames a the centering used temporarily whilst the
concrete or other material of the floor or roof is setting being provided with,
or supporting, core pieces which on being withdrawn when the concrete or the
like is set leave the openings through which the light passes. Figure 5 shews
a cylindrical instead of a conical opening and lining with a bottom glass h fitted to
be removed and fixed with a spring ring h³.
Figure 6 shews a modified forin with glass at top and bottom and with V shaped
recesses which receive cement or concrete and may be made so as to fit in with each
other or into a brick or terra-cotta arch.

page_text: Figure 7 shews the frame or lining made of wood and Figure 8 shews a floor in
the course of construction before the centering is removed in this case one of the
linings is shewn as level with the upper surface of the floor or roof and the glass
fitted into a rebate therein. The other of the linings shews an ornamented bell
shaped lining with the glass resting on the top. Figure 9 shews a convenient
mode of applying the centering and supporting it from above by means of screwed
rods e and nuts e provided with pieces e³ which take into the linings a and pass
through the beams ff' above and below, the lower ones supporting the centering
and the upper ones being carried by the rafters joists or beams g. The linings
here shewn are made with chanelled flanges so that they fit together and form
a continuous under surface. One of the said linings is shewn separately drawn to
a smaller scale in Figure 94 to make this clear. Figure 9B represents a part in plan
drawn to the same scale as Figure 9 the intersections of the ribs being filled with
bosses one of which is shewn at X in Figure 9. Figure 10 shews a lining for a
roof with a curved glass covering at the top and with openings a² beneath it for
ventilation. Figure 11 shews the same with a lower glass h. Figure 12 shews the
linings taking the form of a series made in one piece some of the glasses being at
top and others entirely filling the joist openings Y such as may be used to support
the linings. Figure 13 shews the lining and the glass formed in one. It will from
the foregoing description be readily understood how the invention may be applied
generally to such structures as it is or may be applicable to.
Having now described and particularly ascertained the 1e of my said
Invention and in what manner the same is to be performed I do that what
I claim is
First. Flooring with openings therethrough and with lenses or glasses forming
a level surface to the flooring above and constituting a means of lighting a place
beneath the flooring substantially as herein before described.
Second. In floorings roofs and other structures openings or passages formed by
linings frames or supports of a tubular or conical or other form longitudinally and
of any suitable cross section with which are combined glasses or lenses substantially
as and for the purpose herein before described.
Third. The several arrangements or combinations of parts constituting the
several constructions of floors roofs or other structures for the purposes herein-
before described and illustrated by the several figures of the accompanying
drawings.
