Complete Specification Left. 10th Mar.. 1898—Accepted 16th Apr. 1898
I, GEORGIANA FRANCES LEWIN, of 7, Higher Eaton Place, Exeter, Gentlewoman,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a sash fastener which provides a simple means for
securing the sashes without danger of opening from the outside.
In carrying out my invention I employ a box or case fitted to the meeting rail
of the upper sash, pivoted close to one end, and fixed to a plate. The pivoted end
is rounded and turns on a plate which is screwed to the meeting rail on which the
case is fitted. The other end of the case is open and through this end projects a
plate which is employed for locking, purposes. This plate is secured inside the
case but is adapted to slide a short distance, a slot being employed through which
a pin fixed on the case passes. The plate is provided with a small projection or
finger piece by which it can be operated. The end of this plate carries a hinged
extension which is adapted to be turned vertically.
The front of the meeting rail of the lower sash is provided with a small button
or hinged catch, and the extension above described is provided with a slot through
which this button can pass. To lock the sashes the case is turned round so as to
project over the other meeting rail and the hinged part is turned down. The
extension of the plate is then pushed down and the button caused to project through
the slot. On turning round the button the fastening is secured. The window
cannot be opened until the case has been turned back." The plate is formed with
a curved recess at each side against which springs inside the case bear, so that the
plate is held in position, but at the same time is allowed to be moved by hand.

I, GEORGIANA FRANCES LEWIN, of 7, Higher-Eaton Place, Exeter, Gentlewoman,
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 sash fastener which provides a simple means for
securing the sashes without danger of opening from the outside.
In carrying out my invention I employ a box or case fitted to the meeting rail
of the upper sash, pivoted close to one end, and fixed to a plate. The pivoted end
is rounded and turns on a plate which is screwed to the meeting rail on which the

The other end of the case is open and through this end projects a
plate which is employed for locking purposes. This plate is secured inside the
case but is adapted to slide a short distance a slot being employed through which
a pin fixed on the case passes. The plate is provided with a small projection or
finger piece by which it can be operated. The end of this plate carries a hinged
extension which is adapted to be turned vertically.
The front of the meeting rail of the lower sash is provided with a small button
or hinged catch, and the extension above described is provided with a slot through
which this button can pass. To lock the sashes the case is turned round so as to
project over the other meeting rail and the hinged part is turned down. The
extension of the plate is then pushed down and the button caused to project through
the slot. On turning round the button the fastening is secured. The window
cannot be opened until the case has been turned back. The plate is formed with
a curved recess at each side against which springs inside the case bear, so that the
plate is held in position, but at the same tinie is allowed to be moved by hand.
Referring to the accompanying sheet of illustrative drawings.
Fig. 1 is a vertical section showing a fastener constructed according to this
invention and Fig. 2 is a plan thereof.
at c.
A box or case a is fitted on the meeting rail b of the upper sash and is pivoted
The pivoted end is rounded and turns on the plate which is screwed to the
meeting rail b. The other end of the box or case a is open and through this projects a
sliding plate e which is arranged therein. A slot is formed in this plate e in
which fits a pin f so as to regulate the extent of motion and an operating knob g
is provided to facilitate its manipulation. A plate is hinged to the end of the
sliding plate e and is provided with a slot into which a small button or catch i
upon the meeting rail 1 of the lower sash engages when in the fastening position.
In order to lock the sashes, the box or case a is turned round so as to project
over the other meeting rail and the sliding plate e is drawn out. The hinged plate h
is then turned down and fitted over the button i to secure it in position.
Recesses are formed in the sliding plate e as shown with which engage springs k
fitted within the case a so that the plate is held in position, but at the same time is
allowed to be moved by hand.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) An improved sash fastener consisting of a box or case pivoted at one end on
the meeting rail of the upper sash, a sliding plate arranged within said box or case
and provided with a hinged plate or extension and a button or catch upon the
meeting rail of the lower sash with which the hinged plate or extension engages
when the parts are in the fastening position substantially as described.
(2) An improved sash fastener consisting of the box or case a pivoted at c upon
the meeting rail of the upper sash, a sliding plate e having recesses with which the
springs k engage, a hinged plate or extension h, and a button or catch i upon the
meeting rail of the lower sash with which the said hinged plate or extension h
engages when the parts are in the fastening position substantially as described with
reference to the accompanying drawings.
