PROVISIONAL STOLPICATION.
Improvements in and connected with Window Sashes and
the like.
WILLIAM CHARLES BRETT Mechanical Engineer 45 High Street Homerton.
I do hereby declare the nature of this invention to be as follows:-
:-
Window sashes of ordinary construction as usually fitted are made to slide
up and down in grooves, and are incapable of being reversed for cleaning or
repairing.
My invention has for its object the effective and inexpensive conversion of such
sashes into what are commonly known as reversible or revolving sashes, and also
the construction throughout of reversible sashes.
I swing the sash or sashes upon hinges or studs working upon each side of the
sash and upon runners which slide freely in the groove between the beads of
window frame.
The sash cord is affixed to the runner, which is preferably of same length as the
side of window sash. The sash swings from the runner by connecting hinges or
studs at about the centre of gravity. In these runners I cut a longitudinal plough
groove or rabbet and in the sash I cut a corresponding groove. A strip of wood
or metal is inserted in these grooves, forming a firm connection between sash and
runner when in position. The strip may be flat, or cylindrical in section, in which
latter case it is split down its length and turned by means of a key at top or
bottom. When the split is at right angles to the window, the sash is locked from
revolving on its axis. When using a flat strip I fit a small lever or projection to
the strip for bringing it entirely within the sash and free of the runner, allowing
sash to revolve upon the aforesaid stud or hinge.
By cutting the slot in sash, from which the lever projects, in a sloping direction
or by an arrangement of pins and lever I obtain an automatic action of the stud, so
that immediately upon the sash being brought into an upright position (parallel
with the runner in frame) the strip falls into the groove in runner by its own
weight, securing the sash from turning.
When open the sashes will swing entirely round between the frame or runners
on each side, but when closed by the strip a completely weather proof joint is
made.
COMPLETE SPECIFICATION.
Improvements in and connected with Window Sashes and
the like.
I, WILLIAM CHARLES BRETT, of 45 High Street, Homerton, London, E., Gas
and Hot Water Engineer, do hereby declare the nature of my said 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 relates to sliding sashes and swing windows; and its object is to
fit sliding sashes with improved appliances, whereby such sashes may be converted
into swing windows, when required, and reinstated as ordinary sliding sashes; my
invention being also applicable to permanent swing windows.
And in order that my said invention may be particularly described and ascertained,

page_text: Teference is hereby made to the accompanying drawings, in when simmar ngures
of reference, indicate corresponding parts.
Fig. 1 is an elevation of an ordinary pair of sliding sashes fitted with my
improvements.
Fig. 2 is an elevation, partly in section, of a portion of one of the sashes.
Fig. 3 is a section on the line 1-2, showing the draught excluder in its closed
position.
Fig. 4 is a similar section, showing the same draught excluder in its open
position.
Figs. 5 and 6 illustrate, in sectional elevation, a modification of my invention ;
Fig. 5 showing the sash and runner fixed, and Fig. 6 showing the same arranged
for swinging on its pivot.
Fig. 7 is a top view of Fig. 5, and Fig. 8 is a section on the line 3-4 of
Fig. 6.
is the meeting bar of the lower sash. 6 is the bottom bar of the same. 7 is
the left hand stile. 8 is a runner to which the cord 9 is attached.
The stile 7 is pivoted to the runner 8 by means of two metallic plates 10, 11;
the plate 10 being recessed in and fixed to the stile 7, and the plate 11 being
recessed in and fixed to the runner 8. 12 is a pivot riveted to and uniting the
plates 10 and 11.
The pivot 12 is placed at or near the centre of gravity of the sash. 13 is a
draught excluder, consisting of a strip or tongue of metal or other suitable material,
working in grooves formed in the stile 7 and runner 8, as shown in section in
Figs. 3 and 4. 14 and 15 are two diagonal slots formed in the tongue 13, working
on pins fixed in the stile of the sash. 16 is a small knob fixed to the tongue 13,
and projecting through a diagonal slot in the stile. Both sides of the sashes are
similarly fitted.
When it is desired to revolve one of the sashes upon its pivots 12, the strips 13
on each side are raised by means of the knobs 16. The sash is then free and
capable of being placed in any position, diagonally or horizontally. When the
sash is returned to a vertical position, the strips 13 fall back of their own weight
into the position shown in Fig. 3.
Figs. 5, 6, 7 and 8, illustrate another method of mounting the sash. Two
segmental rods (or two semi-cylindrical portions of a tube) 17, 18, are riveted
together so as to rotate upon the rivet 12. A semi-cylindrical groove is made in
the stile 7, and a similar groove in the runner 8, to receive the rods 17, 18. When
inserted in the grooves, a plate 19 is screwed to the top and bottom of the sash
frame, on each side, as shown; and similar plates 20 are screwed to the runner 8,
as shown; whereby the two portions of the rod are firmly held in position.
The segmental rods 17 and 18 may be otherwise fitted to the stile 7 and
runner 8. A space 21 is provided between the upper plates 19, 20, for the insertion
of a key, whereby the rods 17, 18, may be turned in their sockets. When the rods
are in the position shown in Figs. 6 and 8, the diametrical faces of the segmental
rods 17, 18, are in line with the meeting faces of the stiles 7 and runners 8, in
which position the sash may be swung upon the pivots 12, while the runners 8
remain in their grooves.
When the rods 17, 18, are turned round by the key
90 degrees, as shown in Figs. 5 and 7, the styles and runners are thereby locked in
parallel lines, and the sash resumes its ordinary character of a sliding sash. The
rods also act as draught excluders, when so turned.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in and connected with window sashes and the like, sub-
stantially as hereinbefore described and illustrated by the drawings.
と
2. In convertible window sashes as aforesaid, the combination therewith of pairs

page_text: of segmental rods or semi-cylindrical tubes, united together by riveted pivots,
inserted in semicircular grooves in the stiles and runners, and capable of rotating
upon their longitudinal and transverse centres, substantially as and for the purposes
hereinbefore described and illustrated by the drawings.
