I, RICHARD JAMES TRELEAVEN, of 2, Holborn, London, E.C., Confectioner, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to improvements in combination sliding and hinged
window-sashes and in accordance therewith, I fashion the ordinary sliding window-
sashes preferably of somewhat broader form than usual, and provide inner or
central sashes, which are hinged to the said sliding sashes.
These inner or central sashes, to which the window panes are fixed in the
ordinary manner, close in to the sliding sashes, when shut, so as to be flush upon
one side.
The back (or that side which is exposed to the weather) of each sliding sash,
is provided with a flange or beading around the opening which receives the hinged
sash aforesaid, against which beading or flange a bevelled beading provided upon
the inner edges of the back of the hinged sash frame abuts when the latter
is closed.
By this means, a tight joint is formed between the sliding and hinged sashes,
which will prevent the entrance of external air or moisture, the bevelled shape
of the beading causing rain and the like to run off the window on to the sill
without finding an entrance into the compartment or the like provided with these
combination window-sashes.
The hinged sashes may be so arranged as to open inwardly or outwardly,
whichever is found desirable or convenient, and the hinges aforesaid may be
situated at the sides or any other convenient parts of the sashes.
Dated this 24th day of January 1899.
I, RICHARD JAMES TRELEAVEN, of 21, Holborn, London-E.C.,. Confectioner, do
hereby declare the nature of this invention and in what manner the same is to be
o performed, to be particularly described and ascertained in and by the following
statement:.
This invention relates to improvements in combination sliding and hinged
window-sashes, and is designed with the object of providing a window which,
while capable of being opened in the usual sliding manner for general purposes,
CD 077

page_text: can be readily opened inwardly or outwardly, whichever is desirable or con-
venient, so as to enable both sides of the glazed parts to be readily accessible for
cleaning and analogous purposes.
Further objects and advantages of the invention will be fully understood from
the following description and claims when taken in conjunction with the accom-
panying sheet of illustrative drawings, wherein :-
Fig. 1, is a perspective view of a window in accordance with my invention,
and
Fig. 2, a vertical sectional view of the lower sash.
In the said drawings, wherein similar letters of reference indicate corresponding
parts wherever occurring throughout the several views, a indicates a window
frame of ordinary construction, in which are hung (by means of sash-lines, pulleys
and weights in the usual manner) sliding sashes band c.
To the sliding sash b an inner sash dis hinged at d¹, such sash being adapted to
open inwardly on said hinges.
The sliding. sash b is provided with a rearward flange or beading b¹ around
the opening in which fits the hinged sash d, such flange or beading abutting
against the outer rim of the rear side of the hinged sash when the latter is in its
closed position: A beading d² is provided around the glazed opening in the
sash d, upon the rear side of such sash, the outer edges of which beading fit snugly
over the edges of the flange or beading upon the sliding sash b.
As will be seen, when the hinged sash d is shut to, such sash will close into the
sliding sash so as to be flush therewith upon the inner side.
The flange or beading and the beading d³ are so bevelled as to cause rain and
the like to run off same onto the window sill, without finding an entrance into the
room, for instance, provided with one of my combination window sashes.
The other sliding sash c may be provided with a similar hinged sash to that
before described, or (as shewn) such sliding sash may have two hinged sashes e f
hinged to the sides of the frame a at d¹ and adapted to meet together in the centre
in the manner of ordinary French casements.
The openings g of the window so constructed are glazed in the usual manner.
Although I have described and shewn the hinged sashes as opening inwardly,
such sashes may be so arranged as to open outwardly if found desirable or
convenient, while the hinges instead of being at the sides, may be either at the
top or bottom.
Furthermore, without departing from the spirit of my invention, I may hang
the inner sashes on central or other suitably situated pivots in lieu of hinges if
found desirable, in order that such sashes may be turned upon their pivots so as
to be half in and half out of the room or the like provided with my combination
windows.
Where the peculiar situation of the window renders it necessary, I may secure
the inner glazed sash to the outer or sliding sash, by means of removable studs
or their equivalent, so that such inner sash can be bodily removed from the outer
sash when desired, for cleaning or other purposes.
If found desirable or convenient, I may also dispense with the upper and lower
rails of the outer sash, and retain only the side rails to which the inner sash is
pivoted or otherwise fastened.
Having now 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
1. The improvements in combination sliding and hinged or pivoted window-
sashes, consisting in an inner sash hinged or pivoted to the ordinary sliding sash
and fitting snugly within said sliding sash, said hinged or pivoted sash having an
independent hinged or pivotal movement as well as a vertical movement with the
said sliding sashes, substantially as described and illustrated.
2. In improvements in combination sliding and hinged windows-sashes, the

page_text: combination of the inner sashes d, e, f, hinged to the sliding sashes and having
bevelled beadings d upon one side around the glazed openings, with sliding
sashes b and c within which snugly fit the said hinged sashes, said sliding sashes
having a bevelled flange or beading 61 around the central opening upon one side,
against the edges of which the opposing outer edges of the said beading d² abut
when the said hinged sashes are closed in the sliding sashes, all arranged, com-
bined and operating, substantially as hereinbefore described, and as illustrated by
the drawings.
