IMPROVEMENTS IN SLIDING WINDOW SASHES
Year: 1885

page_text: I, WILLIAM YOULTEN of No 37 Claremont Square, Pentonville N. Architect, do
hereby declare the nature of my invention for IMPROVEMENTS IN SLIDING WINDOW
SASHES to be as follows:-
First, a means by simply turning a knob, of simultaneously opening sliding
window sashes either inwards or outwards, as casements or by means of either
vertical or horizontal centre pivots, thus enabling the admission and exit of air so.
completely to be governed, as to practically prevent the dangerous draughts
inseparable from the ordinary sliding sash system of ventilation. Second,-By
inwardly opening either top or bottom sash at the usual level of the bottom one,
to enable the outside of the window to be cleaned within the room.
These improvements are effected in the following manner:-Inside each of a
pair of ordinary lifting sashes, is hinged or hung on centre or vertical pivots, an
additional sash, thus making the outer sash a casement, sliding frame. Draughts
and wet are excluded by rebated joints and water guard throats. By turning a
knob attached to each casement, the casement becomes detached from the "sliding-
frame" and can be either opened together or singly. If it is desired to clean the
outside of the top sash within the room at the proper level of the lower one, the
sliding frames are so arranged as to make this practicable, by merely reversing
the positions of the sashes, i.e. by raising the lower sash, and lowering the
top one.
"
The outside beads, parting-slips, and inside beads serving as runners for the
sashes in an ordinary frame, can be lengthened to the desired extent to obviate
unsightly heaviness in elevation.
Of course the method of fixing the inner sash within the "sliding frame," would
be varied to suit special requirements, either by hanging as previously described or
otherwise, or by temporarily fixing by means of dowels, tongues, &c.

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:-
$
The improvements claimed are as follows:-By combining the ordinary sash
with that of an inwards opening casement outside window cleaning and painting
can be far more conveniently performed and window gardening much more easily
and effectively carried on than by using the ordinary sliding sash.
These improvements are obtained in the following manner: Inside each of a
pair of ordinary lifting sashes is hinged, hung on centres or secured in any manner
an additional frame (of iron or wood) thus making the outer sash a casement
sliding frame. Either the top or the bottom window can be opened inwards (or
outwards) at the level of the lower.one or if desired can easily be arranged to open
at either or both levels. Draughts and wet are easily prevented by an air tight
hook joint and water guard throat. By turning a knob attached to each casement
(or releasing any other desirable fastening) the casement opens door fashion.
The outside linings parting-slips and inside beads serving as runners for the
ordinary sashes need not necessarily be altered but if desired can have their pro-
jections beyond the face of the pulley stile increased to obviate any unsightly
heaviness in the appearance of the stiles.
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. To abolish the risks attending outside sash cleaning.
2. To effect the benefit by inserting one frame to swing or be temporarily secured
within another.
3. To manufacture such frames either in wood or metal.
