Improvements in the Construction of Window Sashes to Facilitate
Cleaning and other purposes.
I, FREDERICK DE JERSEY CLERE of the City of Wellington, in the Colony of
New Zealand, Architect, 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 a novel manner of suspending window sashes and in
fitting them in their frames so that they can be raised and lowered with facility, and
are pivoted in such a manner that when lowered they can be partially turned so as
to facilitate cleaning painting or other purposes.
In order that my invention may be understood by one skilled in the art to which
it appertains, I will proceed to describe the same, and for that purpose shall refer to
the accompanying sheets of drawings on which similar letters refer to similar parts
in all the figures.
Fig. 1. is a front elevation of the upper part of an ordinary window as designed
for my improved method of construction.
Fig. 2. is a transverse section of the same through the line A. B,
Fig. 3. is a front elevation of the lower part of an ordinary window as designed
for my improved method of construction.
Fig. 4. is a transverse section of the same through the line C. D.
Fig. 5. is a vertical section of the whole window frame and sashes with the lower
sash partly turned.
Fig. 6. is a similar section with the lower sash raised and the upper sash lowered
and partly turned.
Fig. 7. is a side elevation of one form of the slide block to which the sash cord is
attached.
Fig. 8. is a front elevation of the same.
Fig. 9. is an end view of the same.
Fig. 10. is a front elevation of one form of the pivots on which the sash swings.
Fig. 11. is a side view of the same.
Fig. 12. is a front elevation of one form of the hanging block.
Fig. 13. is a side view of the same.
Fig. 14. is a front elevation of another form of hanging pivot and hanger attached
to the sash.
Fig. 15. is a side view of the same.
a, is the sash frame of an ordinary window.
b. b. are the pulley styles having the usual pulleys b', b. These pulley styles
have grooves or rebates, formed in them to receive the sliding blocks which
carry and guide the sashes, and are fitted with hinged beads *, for a purpose
to be hereinafter described.
c. is the lower window sash.
d. is the upper window sash.
c is the sash cord of the sash c.
d' is the sash cord of the sash d.
shews the position of the pivots on which the sash c. turns.
d shews the position of the pivots on which the sash d. turns.
e, e, in Figures 7, 8, 12 and 13 are two forms of sliding blocks which are fitted to
the pivots and so that the sashes may turn within them, and which also can
slide up or down in the grooves or rebates b² and b³.

page_text: purpose and for easy removal. In Figures 12 and 13 these cords are shewn let into
a hole in the block, and retained by the screw e³, and by these means the cords can
easily be regulated in length.
fin Figures 10 and 11 is a plate let into the side of the sash and fastened by
screws, and fitted with a projecting pivot on which the sash turns when
the said plates are fixed in position at c and d in Figures 5 and 6. The
points are made conical in order to steady and retain the sash in its place,
and they fit into recesses or bearings f³, so formed that they can be easily
removed.
g. is another form of plate fixed to the sash in the same manner as f, or any suitable
manner, but having a pivot g' formed on it so that the sash may be hung to the cord
by wires g³, which are themselves attached to the sash cord or ribbon; by which
means the sliding block may be dispensed with and the pin g' work in the grooves b² b*
without a guide block.
It will be seen from this description of the several parts, and by reference to
the drawings that I form in the pulley styles of an ordinary window sash,
grooves in which blocks and pivots of a novel form slide upwards or down-
wards, and carry the upper and lower sashes on suitable trunnions, that the upper
portion of the ordinary parting bead is of the usual form, but its lower part and
the lower part of the staff beads are hinged so as to leave when opened outwards a
clear space at the lower part of the frame in which either sash may swing on pivots
placed at or near the centre, so as to leave sufficient movement to clean, or paint
either side of the window, without removing it from its place, that the upper sash
can be brought down into this clear space and that either sash may be swung within
the same as desired. That the pivots are so formed that the sashes can be easily
removed, the sash cords adjusted in length, and the whole arrangement is simple
and inexpensive, and moreover existing sashes of the usual form which are hung
with cords within the sides of the sash frame, can by simply being cut away on
the part opposed to the cord be hung and actuated in the same manner and altered
at a very small expense.
It will be evident that the hinged parting beads may be recessed in the pulley
styles, and bolted or otherwise fastened instead of being hinged.
I wish it to be understood, that I am aware sashes have been so hung that they
can be cleaned on both sides from within.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the зane is to be performed, I declare that what I
claim is :-
1st. The combination of a window frame and sash, having hinged or movable
parting and staff beads, with grooved recess or recesses 62, with divided sliding
blocks such as shewn in Figures 7 and 8, placed at or near the centre of the sash,
substantially as and for the purposes herein described and illustrated in the accoin-
panying drawings.
2nd. The combination of a window frame and sash, having hinged or movable
parting and staff beads with grooved recess or recesses, such as 3, with sliding
block as shewn in Figures 12 and 13, and pivots such as placed at or near
the centre of the sash as and for the purposes herein before described and
illustrated.
3rd. The combination of a window frame and sash having hinged or movable
parting and staff beads, with grooved recess or recesses such as with pivot such
as g', and wire g³, substantially as and for the purposes hereinbefore described and
illustrated.
