Improvements in the Construction of Fastenings for Windows.
I, WILLIAM KELLY LEE, of 91c, Cardiff Road, Aberdare, Window Blind Maker,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of window fasteners,
and its object is to provide a simple form of fastener which will draw the sashes
tightly together, and which will not be liable to opening from the outside.
In carrying out my nvention I propose to fix on the meeting rail of the upper
sash a small plate having a ledge or extension at the front and two small lugs
between which a pivoted locking arm is carried. This locking arm is formed
with a longitudinal slot, and is provided at its end with a knob or handle, the
lower end of which is furnished with an arm which can be turned round into any
desired position. On the other meeting rail a bent or recessed plate is screwed
carrying a curved stop or plate projecting vertically from the surface. On push-
ing down the locking arm this curved plate projects into the slot, and as the arm
is pushed down bears against the end of the slot and draws the sashes tightly
together. When the arm is properly pushed down the knob is turned causing the
arm attached to it to be turned under the plate on the second meeting rail, thus
preventing the locking arm being pushed back. The extension or ledge on the
first plate prevents the locking arm being pushed too far back so as to strike
against the window, and a small spring is furnished at the pivoted part which
turns the locking arm into either closed or open position.

Improvements in the Construction of Fastenings for Windows.
I, WILLIAM KELLY LEE, of 91c, Cardiff Road, Aberdare, Window Blind Maker,
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 new or improved construction of fastenings for
windows and in accordance therewith in a simple manner, I provide means of
construction suitable for the above mentioned purpose whereby a window can be
fastened and securely locked by the following means: and in order that I may
be fully understood I will describe same with reference to the accompanying
drawings, by which Fig. 1 represents side view of my new or improved fastener
CD Q77

page_text: when locked, Fig. 2 is a side view with fastener unlocked and F. 3 represents
the front view of fastener when locked. Figs. 1, 2, 3, is the fastener having a
slotted stem or arm A, which, when drawn over tooth B tightens the sashes
together the knob C then on being turned, turns foot D under plate E thereby
locking fastener. To unlock turn knob C back foot D then turns from under
plate E when arm A can be raised to a vertical position and kept in that position
by spring G which is fixed in plate F and under stem A the same being kept in
position by pin H being passed through shoulders I, attached to plate F, plate E,
is raised in the centre to enable foot Ď to pass under for locking, plate F is fixed
by screws J to the outer sash and plate E is fixed to inner sash by similar means.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
The new or improved construction of fastenings for windows whereby the sashes
are drawn together by means of knob C being pulled down over tooth B & turn-
ing foot D under plate E thereby locking all substantially as hereinbefore described
and shewn on the drawings.
