Improvements in Windows with Combined Sliding and
Hinged Sashes.
I, SAMUEL KIRK, of No. 24, Ridley Villas, in the City and County of
Newcastle upon Tyne, Slater, 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 and connected with window sashes
and frames, the improvements consisting in an arrangement of compound sliding
and hinged sashes whereby the danger of cleaning outsides of ordinary sliding sash
windows is removed and the following advantages are secured:
1st. The hinged sash when closed against the sliding sash forms an ordinary
sliding sash. suspended by cords and sash weights in the window frame and presents
the same external and internal appearance.
2nd. By a novel form of "rebated" grooved and tongued joint the hinged sash
closes against the sliding sash perfectly weather and draught tight.
3rd. When the hinged sash is opened or removed entirely, for cleaning repairing
or other purposes, the sliding sash is secured from sliding violently upward, by the
action of the sash weights falling, by means of a lock of novel construction which
also secures the hinged sash when closed to the sliding sash.
4th. By the introduction vertically between the sliding sashes of a T shaped
"bead" lining piece, preferably of some hard wood, an efficient grooved guide is
formed for the sliding sashes on their inner sides and the sliding sashés can be
recorded by the removal of only one portion of this T shaped partition bead.
2
5th. By the formation in the head of the window frame of a cavity, above the
top of the upper sliding sash, into which cavity the lower sash can be pushed up,
the upper sash being pulled down, the hinged portion opens clear of the lower
sash, and to its full extent, and this cavity I propose to utilise for ventilating
the room.
::,
6th. Either hinged sash can be removed entirely by taking out the hinge bolt the
sliding sash being left locked in the frame thus leaving a clear opening for passing
in or out pieces of furniture &c.
DESCRIPTION OF DRAWINGS.
Ii
On the accompanying three sheets of drawings I illustrate my invention as it
may be carried into practical application as to its principal features though I do
not confine myself to minor details of construction.
On Sheet 1, Fig. 1, represents a sectional plan of a window sash and frame with
the hinged sash closed. Fig. 2 a partial section with the hinged sash partly open,
Fig. 2 a section of the sliding sash style shewing the double mortice lock, and
Fig. 3 an elevation of the double mortice lock for locking both the sashes.
On Sheet 2 three sectional views of a complete window are shewn to a smaller
scale; Fig. 4 shewing both the upper and lower sliding and hinged sashes closed
and forming an ordinary sliding sash window; Fig. 5 the upper sashes closed and
the hinged lower sash open into the room for cleaning and Fig. 6 the lower closed
sash pushed up into the cavity so as to clear the upper sash, which has been pulled
down, and allow its hinged sash to be entirely opened into the room for cleaning.
In all three figures the ventilating appliance is shewn. Fig. 7 is a section of the
"sill" of the window frame having an inner weather bead in front of the sashes
which close behind it.
On Sheet 3. Fig. 8: is an internal view of a' window fitted with sashes according

page_text: The same letters apply to corresponding parts on all the figures where such parts
are shown.
A A are the, outside linings of the window frame, B B the styles in which are
the sash cord pullies. C.CCC are the sash weights hung in the box cases of the
frames. DD are the staff beads forming, with the outside linings A A, grooved
guides for the sliding sashes E E' to work in. FF are T shaped vertical bead
pieces inserted into the styles B B separating the sliding sashes E E' and forming
grooved guides for them. G Gare the swinging sash frames hinged to the sliding
sashes at H H. In one side of the sliding sashes E E' is formed the "rebated
groove and tongue into which a similar groove and tongue in the hinged
sashes G Genters when closed and makes a perfectly water and draught tight
joint as shewn by Fig. 1 (Sheet 1). When closed the hinged sashes G Gare
locked to the sliding sashes by the bolt of a double acting mortice lock J. let into
the sliding sash, being shot into a socket in the hinged sash which cannot then be
opened without the key. This lock is shewn by Fig. 3 and as will be seen the
bolt has a double action so that, before the hinged sash can be opened, it must be
shot into a socket in the style B see Fig. 2 (Sheet 1) and thus the sash
prevented from being violently raised by the sash weights falling.
is
The cavity formed in the head of the window frame previously named is shewn
on Figs. 4, 5 and 6 (Sheet 2) and serves the double purpose of. allowing the lower
sash to slide sufficiently high, so as to allow the hinged portion of the upper sash
when pulled down for cleaning to open clear, see Fig. 6, in which the two sashes
are in that position.
The cavity may be adapted to serve as a ventilator by forming the front of
va "louvred or perforated board a the back board b being also louvred or
perforated. A hinged flap c is provided, that is also perforated, and which' when
the sashes are in their normal positions occupies the position shewn in Fig. 4, but
which when the lower sash is pushed up and the upper sash pulled down is turned
back by the top of the lower sash entering the cavity as shewn on Fig. 6 but
without the flow of air being stopped.
· 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 :-
1st. In combined sliding and hinged sash windows the construction of a cavity
in the window frame above the head of the upper sash into which the lower sash
can be pushed up so as to allow the hinged portion of the upper sash when pulled
-down to open clear of the bottom of the lower sash through a complete quarter of
a circle substantially as described and shewn.
2nd. In combination with sliding and hinged sash windows the "rebated" grooved
and tongued joint between the hinged and the sliding sash constructed and operating.
substantially as described and shewn.
3rd. In combination with sliding and hinged sash windows the double acting
mortice lock fitted in the sliding sash constructed and operating substantially as
-described and shewn.
4th. In combination with the cavity formed in head of the window frame. the
application of a ventilating appliance to such cavity constructed and operating
.substantially as described and shewn.
5th. The improvements in windows, with combined sliding and hinged sashes;
consisting of the various parts hereinbefore set forth constructed and operating in
-combination as described and shewn.
