PROVISIONAL SPECIFICATION.
Improvements in and connected with Window Sashes.
I, JAMES NICOL, of 22 Byars Road, Hillhead, Glasgow, Joiner, do hereby
declare the nature of this invention to be as follows:-
This invention relates to window sashes, and it has for its object to so construct
them that they can be easily opened inwards, and the windows readily cleaned
from the inside.
In carrying out my invention, the sides or "stiles" of the sash are divided
vertically into two parts. One part of each "stile," which I may term the sliding
part, is capable of sliding up and down in the sash frame, whilst the other part is
jointed to the top and bottom rails. These parts, together with the rails, form the
frame proper for holding the glass of the window. The frame is hinged, at one
side, to, say, the right hand sliding "stile," and, at the other side, it is locked,
pinned or screwed, to, say, the left hand sliding "stile."
The sliding parts of the "stiles" have grooves in them to enable them to be
easily guided by the "beads" in their vertical movements.
When the parts of the window sash are locked together, it has exactly the same
appearance as an ordinary window sash.
The parts of the "stiles" are so made or cut as to prevent water gaining access
to the interior.
When it is desired to clean the window, all that is necessary is to unlock the
"stile" at one side, and then pull the window inwards, so that it turns on the hinge
or hinges at the other side. In this manner, the window is made to open and close
like an ordinary door.
To prevent the sliding part of the left hand "stile" from being pulled up by the
weights, when the window is being cleaned, a spring, hinged, or other catch is
provided.
Suitable catches may be provided for connecting the sash proper to the sliding
part of the left-hand "stile," when shut.
The upper and lower window sashes are both constructed in the same manner.
The cords may be secured to the sashes in any suitable manner, but, preferably,
by means of counter-sunk plates.

COMPLETE SPECIFICATION.
Improvements in and connected with Window Sashes.
of
I, JAMES NICOL, formerly of 22 Byres Road, Hillhead, and now
15 Vinicombe Street, Hillhead, Glasgow, Joiner, 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 window sashes and it has for its object to so construct

page_text: them that they can be easily opened inwards and the windows readily released
from the inside.
c
And in order that my said invention may be properly understood I have
hereunto appended an explanatory sheet of drawings, whereon :-
Fig. 1 is a front view of the window.
Fig. 2 is a section on the line - Fig. 1.
Fig. 3 is a vertical section showing the half stiles at the left hand side of the
window Fig. 1.
Figs. 4 to 10 are details.
Referring to the drawings whereon the same reference letters wherever repeated
indicate similar parts.
a, b are the two window sashes. c, c¹, the stiles of the sash b and d, d¹ those of
the sash a. The stiles c, c, d, d¹, are divided vertically into two parts 1, 2;
3, 4, 5, 6 7, 8. e is the window frame. f, g, h, are the inner, outer, and parting
beads.
The parts 1 and 4 of the stiles c, c', of the lower sash b are capable of sliding
up and down in the sash frame whilst the part 3 is hinged at i, i, to the part 4
and the part 2 is jointed, in the manner hereinafter set forth, to the part 1. The
half stiles or parts 5 and 8 of the upper sash a are likewise capable of sliding in
the sash frame, whilst the part 7 is hinged to the part 8 and the part 6 jointed to
the part 5.
The divided stiles together with the top and bottom rails form the frames proper
for holding the glass of the window.
•
As will be seen in Fig. 2 the sliding half stiles or parts 1 and 4 and 5 and 8
are cut, on both sides, with vertical grooves; in order that they may be guided
in their vertical movements by the beads f, g, h. The half stiles 1, 4, 5, 8,
are each cut, as shown in Fig. 2, so as to leave a rib or projecting strip k on the
outside in order that water may be prevented from gaining access to the interior of
the room.
When the window is closed the parts 5 and 6 and 1 and 2 are locked together by
means of screwed pins l. These pins, as shown in the enlarged view at Fig. 4, are
made with a hinged head or end which normally hangs down out of the way.
The pins enter holes made in the half stiles 1 and 5.
The half stiles or parts 2 and 6 have catches m on them, (see enlarged views at
Figs. 5 and 6). These catches are made out of pieces of metal which are bent or
folded into the hook shape shown. The hooked part m¹ of each catch enters a
corresponding hole n cut in the sliding half stile. Each hole n is protected by a
metal guard n' (see Figs. 9 and 10).
To prevent the sliding parts of the stiles c, d, being pulled up by the weights,
when the window is being cleaned, a hinged catch is provided. This catch, which
is shown to an enlarged scale at Figs. 7 and 8 consists of a flap o which is hinged
to a plate p secured to the window frame e. When it is desired to lock the half
stile to the frame the flap is pushed into the recess 9 cut in the stile. When the
flap is folded down against the plate p the stile can slide freely up and down in the
frame.
The upper and lower window sashes are both constructed in the same manner.
The cords s may be secured to the sashes in any suitable manner, but, preferably,
by means of counter-sunk plates.
When it is desired to clean the window, all that is necessary is to pull up the
lower sash b until it clears the sill and then unlock the half stile 2 by withdrawing
the screwed pin l. The sash can now be pulled inwards as it turns freely on its
hinges, in the same manner as a door (see Fig. 2). Before unlocking the half
stile 2 the other half stile 1 should be locked to the frame by inserting the hinged
flaps o into the recesses q. The upper sash a can now be pulled down into the
position shown at Fig. 3, and unlocked in the same manner.
Both sashes can now
be easily and readily cleaned.

page_text: 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 :-
The general arrangement or combination of parts of the improved window sash,
substantially as hereinbefore described and shown on the drawings annexed.
