Improvements in Window Sashes, and in Apparatus for Hanging
the same.
I, CHARLES JOSEPH COOZE, of Carterton, in the Provincial District of
Wellington, in the Colony of New Zealand, Carriage Trimmer, 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 objects of my invention are to provide a ready means of hanging window
sashes so that they may slide easily and truly in opening and shutting, and be tilted
or turned completely over so as to be readily cleaned on both sides, or repaired
with facility; also to provide a convenient method of inspecting the pulleys and
cords; moreover by my improved method of hanging, window sashes already fixed
can be readily fitted with my apparatus at a small expense.
My invention is illustrated in the accompanying drawings on which,-
Figure 1 is a front view of a window as arranged with my improvements.
Figure 2 is a vertical section of the same taken through the line A-B.
Figure 3 is a transverse section through the line C-Ď.
Figure 4 is a vertical section through the line E-F shewing how the sash cord
pulleys are arranged for hanging the sashes.
Figure 5 is a plan of the same.
Figure 6 is an enlarged view shewing the slide and sash pivoted together and the
tongue closing the aperture between sash and slide.
Figure 7 is a transverse section of the same through the line G-H.
(a) is the window frame which is of the ordinary form with front frame (b) back
frame (c) and styles (d), the said styles being divided into the usual trenches by
the beads (e) & (/) and the parting beads (9). The beads (e) & (f) have (by
preference) bevelled edges (e¹) & (ƒ¹).
In the trenches of the frame by the ordinary method of hanging sashes, the
window sashes themselves slide, but by my invention I arrange slides (/) to slide in
the said trenches which (by preference) project slightly towards the sash, and are
made to fit to and be guided by the vees (f'), the slides and vees being so
proportioned that they can easily be placed in position or removed therefrom.
The slides (h) I prefer to extend the whole length of the window sashes and to
be pivoted to the same by a pin (¹) placed at or about the center of the said
slide and sash measured vertically. The slides on which the sash turns project
slightly within the frame and beyond the beads as hereinbefore described in
order to allow of the sashes turning with perfect freedom and without touching
the frame.
It will be evident that by swinging one of the sashes, say at right angles to the
window frame, the other can be completely swung round its center and vice versa so
that both the sashes can be reversed and what was before the inside of the said
window may be made the outside thus giving great facility for cleaning both sides
of the glass and repairing the same.
It is necessary for the proper working of the sashes that they should be capable
of being fixed firmly to the slides (h) in ordinary work and that the small spaces
between the window frame and the slide () should be closed to keep out any draft
that might arise, and these objects I carry out in the following manner,-
I prefer to form the slides (h) of thin metal of a section shewn at (2) in

page_text: Figure 7 and I mould or roll them so as to form a groove (i) and strengthen the
said metal slides by a block (1), which also receives the sash and slide suspending
cords (k) & (k), a block (1) which carries the pivot pin (h¹), and also a strengthening
block (m). I also prefer to protect the edges of the sashes with metal plates (o)
(see Fig. 7) screwed or otherwise fastened to the edge of the said window sash and
fitted with a groove (o¹) corresponding with, but being somewhat deeper than the
groove (i) in the slide (h). Within these grooves (i) & (o¹) I fit loosely tongues (p)
which are rather shorter than the side of the sash to enable them to be raised or
lowered without projecting beyond the upper and lower edges of the same.
These tongues when in their normal position are fixed so as to be partly
within the groove (i) and partly in the groove (o¹), and are held in position
by slots or guides (p¹) formed diagonally in the said tongues in such a
manner that if the tongues are lifted they will slide on the pins (p') into
the groove (o¹) so as to free the sash and allow it to swing or turn on
the pin (¹), but on placing the sash again in its normal position the
tongues (p) will fall into the position shewn in Figure 6 effectively preventing
the window sash from turning and also preventing any draft taking place between
the sash and the slide. (J) is a nut which is screwed on to a pin () which is itself
fastened firmly on to the tongue (p), and on applying the fingers underneath these
nuts which are placed on either side of the sash frame, the tongues (p) will be
lifted entirely into the grooves (o¹) and the sash freed ready for turning. On
Ecrewing up the nuts (J) the tongues are fastened in their respective grooves and
the whole made firm to prevent rattling. It will be seen therefore that by lifting
the nuts (J) upwards the sash can be lifted and freed ready for turning by one
operation.
In all arrangements of swinging sashes it is necessary for the proper working of
the same that they should be so hung as to maintain a horizontal position under all
circumstances and for this purpose I prefer to hang my sashes with cords running
over pulleys placed above the top piece (r) but firmly attached to the same and so
that by removing a slip (s) the whole of the pulleys can be at once inspected and I
so arrange the pulleys and weights that one weight counterbalances both sides of
one sash and another weight balances similarly the other sash, for instance, in
Figure 4 the cords 1 & 2 are attached to one weight and are led over the
pulleys 3 & 4 to either side of one sash whilst the weight attached to the
cords 5 & 6 passing over the pulleys 7 & 8 balance tbhe other sash.
I have hereinbefore described a tongue (p) and its guides which I consider most
suitable and convenient to hold the sash firm to the slides and stop the draft space,
but it will be evident that such tongue may be fitted in many ways so as to work
in and out of the groove and parallel with the same, also that instead of grooving
the sash the tongues could be attached to the outside of the sash and slide into
grooves formed on the outside edge of the slides, the slides being made wider for
the purpose; indeed this part of my invention admits of many variations and
applications and is equally suitable where a similar operation is desirable viz., in
French windows, panels, or ventilators.
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 combination of a window sash having pivots (¹) with hanging slides (h)
sliding in trenches formed in the window frame by beads (e) (f) & (g) as and for
the purposes substantially as described herein and illustrated.
2. The combination of a window sash hanging on pivots (/¹) attached to
hanging slides (h) and fitted with tongues (p) working into the said hanging slides
as and for the purposes substantially as described herein and illustrated.
3. The metallic slides (4) carrying sash cord (k) and pivot pin (¹) as and for
the purposes substantially as described herein and illustrated.

page_text: 4. In a window such as described herein the two cords of each sash actuated by
one weight and two guide pulleys having an inspection slip (s) as and for the
purposes substantially as described herein and illustrated.
5. The improved window frame and sash apparatus substantially as described
herein and illustrated.
