I, WALKER STEAD, of Northallerton, Civil Engineer, and County Surveyor for
the North Riding of Yorkshire do hereby declare the nature of my invention for
IMPROVEMENTS IN THE CONSTRUCTION AND HANGING OF VERTICAL SLIDING SASHES
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The invention is for improvements in the construction and hanging of vertical
sliding sashes for windows &c., whereby such sashes may be turned on
an axis
downwards into the room, for the purposes of cleaning the glass, painting,
glazing, ventilation &c., without displacing the position of the sashcords, and to
enable each sash to be readily withdrawn from the frame when required.
The Drawing accompanying this Specification shews the general features of the
invention.
Fig. 1. is a sectional plan of one side of a window frame and sashes, shewing a
rebated formation of the frame and sashes to admit of the sashes turning down clear
of the cords.
Fig. 2. is an elevation of the lower portion of a window frame and its bottom
sash shewing the method of suspending the sash at S. S. and the turning socket T. S.
for the top sash.
The horizontal dotted lines L. L. shew the position of the bottom sash when turned
down for cleaning &c.
Figs. 3. 4 & 5, are full size details of the sash suspender S. S. and the turning
socket T. S. for a window having the sashes two inches thick.
The sash suspender S. S. consists of a metal baseplate carrying an axle A terminating
in a key K as shewn at Fig. 4. The baseplate is screwed or otherwise fastened to the
sash -upon the axle A is fixed a stirrup with corrugated arms C. C. (Figs. 3 & 4) to
grip the sash cord E.
One end of the sash cord is fastened to the weight in the usual way, but the other end
is threaded through a tapering tube D, then placed between the arms or clutches C. C.

firmly to grip the sash cord.
The usual side sashbeads B may be removable, or hinged as shewn at H to turn
aside, for the withdrawal of the sashes.
When the sashes are in the frame the key on the suspender axle, slides vertically in
a groove in the frame and descends when required into the turning socket where the
key can turn freely round, and the sash can be drawn down into the room for
cleaning &c. without displacing the sashcords.
Either sash may be withdrawn from the frame by pulling the key through the
horizontal groove of the turning socket.
The lower portion of the parting strip P to be cut away to allow of the turning
down of top sash.
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 hanging of a vertical sliding sash upon an axle.
2. The method of fastening the sash-cord to the axle by a stirrup clutch, and
tightening the grip by a tapering tube.
3. A sash key sliding in a vertical groove in the frame, descending into, and
revolving within, a turning socket secured to the frame; thereby enabling the sash to
be turned down into the room for cleaning &c.
4. A rebated formation of the frames for vertical sliding sashes &c., to admit
of the sashes being turned down out of the frame without displacing the
sashcords.
