An Improved Ventilating Sash Fastener.
1, SIDNEY GAMBLE, of 6 Chapel Row, Saint Clare Street Penzance, Builders
Clerk, 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 refers to fasteners for hung sashes and for like purposes, and is
designed to supply a fastening which while securely locking the sash in the closed
position, will also fasten it when partly open, so that air can be admitted to a room
without the window being unfastened.
I will now describe the invention with reference to the accompanying drawings
in which
Fig. 1. shows a side elevation of one form of sash fastener where a slotted standard
with moveable arm and fixed rack are employed.
Fig. 2. shows a plan view of same.
Fig. 3. shows a side elevation of a second form of fastener, in which the pivotted
arm is attached to a pivotted dwarf standard and a rack or catch with holes instead
of teeth are employed.
Fig. 4. shows a plan view of Fig. 3.
In all the figures the window is shewn slightly open.
Referring to Figs. 1. and 2. a, is a toothed rack, fixed on the wooden centre bar
of the lower sash.
It has circular depressions a² inside the teeth to receive the transverse stud d¹ of
the arm d.
b is a slotted standard placed on the centre bar of the upper sash and furnished
with a combined hinged and pivot joint c.
bis the slot in standard b.
d is a moveable connecting arm working between the two parts of the fastener,
one end sliding in the slot b' of standard b, and permanently attached thereto,
and the other furnished with a small stud d' for the purpose of engaging with the
teeth of rack a.
This stud can be locked into the teeth of rack a. by a split pin a¹ attached to a
small chain a thus preventing the fastener from being opened from outside
the sash.
Referring to Figs. 3, and 4, e is a standard pierced with holes e¹ which may be
used instead of the rack a in Figs. 1 and 2.
fis a hinged and pivotted dwarf standard with hole to receive the base of the
arm d, Figs. 1 and 2.
It will be understood from the drawings that the connecting arm d, turns to right
or left, and can thus be placed out of the way of the sash when disengaged from
the standard d or e.
When it is desired to close the sash the stud d' of the arm d is fixed in the
topmost recess a or in the uppermost hole e¹ and is locked by the pin a' or by some
other well known device.
When the sash is preferred partly open, the stud d' can be engaged with either
of the lower recesses or holes.
The arm d can be made of any preferred section and may have a thumb-bit, as
shewn by d² or an open ring for the finger attached to the fore end of same.

page_text: My improved sash-fastener will be found to answer all the requirements of
ventilation and safety, and to confer a valuable boon on sleepers in hot weather,
when the circulation of air is, so necessary to health.
By elongating the catch standard, the sash will open further than shewn in
drawings.
For large and heavy sashes two of the fasteners can be employed. One will
be sufficient for ordinary windows.
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;
In a ventilating sashfastener a vertical standard preferably hinged and pivotted,
and either slotted or otherwise perforated to receive the rear end of an adjustable
pivotted connecting arm the fore-end of which engages by means of a stud with
recesses or holes on a second and rigid standard, in such a way as to secure the
window when closed or when partly open, as herein described and set forth.
