PROVISIONAL SPECIFICATION.
Improvements in Lenses and Holding Frames of Lenses Employed
as Floor Lights, Skylights, Deck, and other like Lights.
We, ROBERT WILSON, and SIDNEY GOODMAN, both of 24 Harrison Street, Gray's
Inn Road, London, W.C., Engineers, JAMES SHEPPARD of Trayshill, Hornsey Lane,
London, N., Surveyor, and FREDERICK DASHWOOD, of Lindisfarne Walton-on-
Thames, Surveyor, do hereby declare the nature of this invention to be as follows :—
This invention consists of an improvement in glass lenses employed for transmitting
light, together and in combination with a holding frame designed to prevent water of
condensed moisture dripping from surface of the lense or lenses.
The lenses are constructed in various forms, dependant upon the nature of the
requirements for reflecting or transmitting light, but in all cases the formation of the
underside of the glass is concave, which causes the water to run to the outer edges
of the lenses, and where the lenses are required to be prismatic or reflecting, the
prisms are made concave on the lower edge, so that the water must run to, and off
at the sides of the lenses.
The holding frames for the lenses are divided into squares or other figures, corre-
sponding to the outline of the lenses, and provided with rebate or ledges to receive
and hold the lenses, and below or communicating with the outline of the lense or
lenses, is a trough or gutter projecting inwards a little beyond the rebate of the
frame carrying the lenses, so as to receive and carry off the water of condensation.

Improvements in Lenses and Holding Frames of Lenses Employed
as Floor Lights, Skylights, Deck, and other like Lights.
We, ROBERT WILSON, and SIDNEY GOODMAN, both of 24 Harrison Street, Gray's
Inn Road, London, W.C., Engineers, JAMES SHEPPARD of "Trayshill," Hornsey
Lane, London, N., Surveyor, and FREDERIOK DASHWOOD, of Walton-on-Thames,
Surveyor, 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 :-
This invention consists of an improvement in glass lenses employed for transmitting
light, together and in combination with a holding frame designed to prevent water
of condensation dripping from the surface of the lense or lenses, or from the carrying
frame, and the invention consists in making the lenses of such shape that the water
of condensation runs off same, to and is collected in, a trough or channel formed in
the frame.
Such being the nature and object of our said invention, the following is a complete
description of same, reference being had to the accompanying drawing, which is an
oblique view, partly in section, of a series of lenses in their carrying frame.

page_text: According to this invention, the lenses 1. 1 are constructed in various forms
dependant upon the nature of the requirements for reflecting or transmitting light,
but in all cases the formation of the underside of the glass is concave as shewn,
which causes the water to run to the outer edges of the lenses, and where the lenses
are required to be prismatic or reflecting, the prisms are made concave on the lower
edge, so that the water must run to, and off at the sides of the lenses.
The holding frames 2. 2 for the lenses 1. 1 are divided into squares or other
figures corresponding to the size and outline of the lenses 1. 1., and provided with
rebates or ledges 3. 3 to receive and hold the lenses 1. 1, and below or communicating
with the outline of the lense or lenses 1. 1, and in the frame 2 is a trough or
gutter 4 projecting inwards a little beyond the rebates 3 of the frame 2 carrying
the lenses 1. 1, so as to receive and carry off the water of condensation.
This combination of lense and frame gives a horizontal light which prevents the
moisture formed by condensation, falling on anything which happens to be below.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
(1) A concave lense combined with a carrying frame in which is a trough or
gutter for collecting the water of condensation as horein described and substantially
as illustrated by the annexed drawing.
(2) A carrying frame for prismatic or other deck and pavement lights, having a
ledge or rebate and below and projecting beyond same a trough or gutter, all in
combination as and for the purpose herein described and substantially as illustrated
by the annexed drawing.
