PROVISIONAL SPECIFICATION.
A Novel Arrangement of Window Frames or Sashes and the
Fasteners therefor.
HUGH MCKIBBIN of 15 Percy Street Belfast Ireland Mechanic do hereby declare
the nature of this invention to be as follows:-
This invention of a novel arrangement of window frames or sashes and the
fasteners therefor consists in hinging the lower portion of the sash on its lower edge
and hanging the upper portion of the sash on cords and pullies in the ordinary manner
with slides, both the lower and upper part of the sash being in the same plane when
closed thus the lower or swinging portion of the sash forms a key or fastener for the
upper part when closed.
The lower or hinged portion of the sash is fastened when closed or is held open by
a notched quadrant which is swung upon a centre or pivot projecting from the inside
face of the lower portion of the sash. This notched quadrant passes through a plate
fastened to the stile or casing and when the window is closed the quadrant hangs
down within the stile which is trenched to receive it. Attached to the plate is a locking
lever that can be turned into or out of the notches in the quadrant and so secure or
liberate it. By turning the locking lever into one or other of the notches in the
quadrant the lower portion of the window is held secure in any required position.
There is a snug on one side of the end of the quadrant to prevent it from coming
out through the plate but when it is required to remove the lower part of the sash
the quadrant is simply lifted up and the snug on the side of the end of the quadrant
passes through a recess formed in the plate.
By this arrangement of window frame and fastener increased facilities for
ventilation are obtained with perfect security and at the same time both sides of the
window are more easy of access for cleaning or other purposes for both sides of the
lower part of the sash are accessible from the inside when it is open and when it is
removed the upper part of the sash can be brought down into the space vacated by
the lower part of the sash and so be easily brought inside for cleaning or other
purposes.
COMPLETE SPECIFICATION.
A Novel Arrangement of Window Frames-or-Sashes and the
Fasteners therefor.
HUGH MCKIBBIN of 15 Percy Street Belfast Ireland Mechanic 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 of a novel arrangement of window frames or sashes and the fasteners
therefor is illustrated in the sheet of drawings herewith the same letters and figures
of reference being employed to indicate the same or like parts..
Fig. 1 is an inside view of a window closed.
Fig. 2 is a section of the same.
Fig. 4 is an inside view of an open window.
Fig. 3 is a section of the same.
Fig. 5. 6 and 7 are detached views of parts on a larger scale than Fig. 1. 2. 3
and 4.
This invention consists in hinging the lower portion (a) of the sash on its lower
edge and hanging the upper portion (a¹) of the sash on cords and pullies in the

page_text: ordinary manner with slides both the lower (a) and upper part (a) of the sash being
in the same plane when closed as shewn in Fig. 1 and 2. Thus the lower or
swinging portion (a) of the sash forms a key or fastener for the upper part (a)
when closed.
The lower or hinged portion (a) of the sash is fastened when closed or is held open
by a notched quadrant (c) which is swung upon a centre or pivot (c) projecting
from the inside face of the lower portion (a) of the sash. This notched quadrant (c)
passes through a plate (d) fastened to the stile or casing (e) and when the window
is closed the quadrant (c) hangs down within the stile (e) which is trenched to receive
it as shewn in dotted lines in Fig. 2 and 3.
Attached to the plate (d) is a locking lever (d') that can be turned into or out of
the notches (c) in the quadrant (c) and so secure or liberate it.
By turning the locking lever (d) into one or other of the notches (c) in the
quadrant (c) the lower portion (a) of the window is held secure in any required
position.
There is a snug (c³) on one side of the end of the quadrant (c) to prevent it from
coming out through the plate (d) but when it is required to remove the lower part (a)
of the sash the quadrant (c) is simply lifted up and the snug (c³) on the side of the
end of the quadrant (c) passes through a recess (d2) formed in the plate (d).
The lower portion (a) of the sash is swung or hinged on its lower edge on hinges (f)
described in letters patent No. 7341. 20 May 1887 by means of which the lower
portion (a) of the sash can be easily removed when required.
By this arrangement of window frame and fastener increased facilities for venti-
lation are obtained with perfect security and at the same time both sides of the
window are more easy of access for cleaning or other purposes for both sides of the
lower part of the sash are accessible from the inside. When it is open and when it
is removed the upper part of the sash can be brought down into the space vacated by
the lower part of the sash and so be easily brought inside for cleaning or other
purposes, without removing any slips or guides from the casing.
.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 1
claim is
The arrangement of window frames or sashes and the fasteners therefor herein
described and illustrated in which the upper and lower portion of the sash are in one
plane when closed and in which the notched quadrant or fastener is hidden within the
framing when the window is closed.
