COMPLETE SPECIFICATION.
Improvements in Window Casements.
1, EDWARD INGRESS BELL, of 19, Queen Anne's Gate, Westminster, 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 :-
This invention relates to improvements in window casements and has for its
object to provide. in such casements, and more particularly in that type of case-
ment known as the "Croydon casement," a means of carrying off the condensed
This said "Croydon casement"
water from the inside of the glass of the window.
generally consists of a flat bar of metal and the frame is formed by adjusting
and screwing to the stone or woodwork four slips (one on each side, one at top
and one at bottom) which project beyond the face of the rebates, and thus form
a perfect throating all round.
To effect the object of this invention in casements of the aforesaid type I have
formed inside upon the top of the bottom rails of the casement "and close to the
glass, a groove or channel for collecting the condensed water from the glass.
Leading from the grooves or channel aforesaid and suitably formed in the bottom
rail I have provided drip conduits or apertures through which the water as it
collects will flow to the outside of the casement.
And in order that this my invention may be fully understood and readily carried
into effect I will now proceed to describe same with reference to the accompanying
drawings and to the letters and figures of reference marked thereon, that is to say:
Figure 1 represents in sectional side elevation the lower portion of a "Croydon
casement fitted with condensed water collecting channel or groove and drip
conduit and as hung to stone, terra cotta or bricks. Figure 2 is a plan of the same
also in section.
"
Figure 3 is a similar view to Figure 1, but in which the casement is hung to
wood frames.
Figure 4 is a sectional plan of the casement and fittings shewn in side elevation
in Figure 3.

Figure 5 illustrates another form of groove or channel and drip conduit as applied
to a Croydon casement
be fixed to either wood or stone.
which may
Figure 6 shews a construction of casement and bottom rail with channel and
conduit alternative to that shewn in Figure 1.
In all the figures similar letters of reference relate to like parts.
Referring particularly to Figures 1 and 2, a is the groove formed in the bottom
rail 6 of the casement for the purpose of collecting any moisture draining from the
inside of the glass c. Apertures d either circular, or as in the case of Figure 5
semicircular, are drilled at suitable intervals in the groove or sloping surface a and
extend downwards through the bottom rail and serve as conduits for the condensed
water to flow to the outside of the casement.
In these figures, e represents the lead band in which the glass is fitted, and the
oil cement used; whilst in Figure 1, g is the sill or transome as the case may be
and in Figures 2 and 4, h is the jamb or mullion.
In windows with mullions and transomes, it frequently happens that some of the
5 lights are fixed. It is as necessary to provide for condensation in these cases as in
the lights which have casements which open. This is easily accomplished by
screwing the double chamfered bottom bar on to the rebated sill or transome, even
if the lights are built into rebated frames.
In Figures 3 and 4 (respectively side elevation and plan of a "Croydon casement."
Das hinged to wood frames and fitted with the drip groove and conduits in accordance

with this invention), a represents a groove of a different shape to that shewn in
Figure 1. b. c. d. e.f.g and h represent respectively similar parts to those they
indicate in Figures 1 and 2, but in Figure 4, i shews a gun metal hinge upon which
the casement is hung. Figures 5 and 6 represent yet other forms of drip groove
and conduits as applied to casements and it will be readily understood that a
variety of styles or shapes of groove or channel may be employed without departing
from this invention.
In order to facilitate the flow of water collected in the drip groove through the
drip conduits, the bottom of the groove may be formed between the drip apertures
slightly slanting, so that any water therein contained will naturally How to the
drip aperture and thereby be directed to the outside of the window.
Having thus particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim, is:
In casements of the "Croydon " type, the construction of the bottom bar or rail
of either an upper or lower casement with groove or channel on the upper side or
surface thereof, and drilled at suitable intervals with apertures leading from the
groove or channel aforesaid to the outside of the casement for the purpose of
collecting or receiving the water of condensation formed upon the inside of the
glass and conducting or delivering same from the inside to the outside substantially
as hereinbefore set forth and shewn in the accompanying drawings.
Dated this 24th day of March 1893.
