Complete Specification Left, 29th Apr., 1896-Accepted, 30th May, 1896
I, RALPH NAIM ALLISON of 5, St. Julians Road, Kilburn, Traveller, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of sash fasteners, and
has for its object to provide a simple and inexpensive device which will render such
fasteners less liable to being opened from the outside.
In carrying out my invention, I employ for preference a fastener similar in style
to that commonly used in which a pivoted bar is fitted on one meeting rail, the bar
being moved over the other meeting rail in securing the window.
Instead of forming the said bar in one piece with a handle at the extremity,
I furnish it with a hinged extension to which the handle is fitted. This extension is
adapted when the fastener is in locking position to drop over the face of the inner
meeting rail. By this means any attempt to open the fastener without raising the
extension from the inside will only result in pressing the edge of the extension
against the face of the meeting rail, thus forming a stop which prevents any motion
of the locking bar.
In order to render the fastener more secure, a groove may be cut in the face of
the meeting rail in which the extension will drop, or a small plate may be secured
furnished with a projecting face or stop against which the extension will bear. The
extension may also be slotted so as to engage with a pin fitted to the meeting rail
or any other form of stop may be employed.
According to a modified form of fastener the locking bar may be cut or notched
and the securing piece dropped into the notch or recess, or the bar may be
perforated and a pin employed, which when the fastener is secured will drop
automatically into the hole, locking the fastener effectually.

I RALPH NAIM ALLISON of 5 St. Julians Road, Kilburn, Traveller, 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 improvements in the construction of sash fasteners, and
has for its object to provide a simple and inexpensive device which will render such
fasteners less liable to being opened from the outside.
In carrying out my invention, I employ for preference a fastener similar in style
to that commonly used, in which a pivoted bar is fitted on one meeting rail, the bar
being moved over the other meeting rail in securing the window.
Instead of forming the said bar in one piece with a handle at the extremity,
I furnish it with a hinged extension. This extension is adapted when the fasteuer is

any attempt to open the fastener without raising the extension from the inside will
only result in pressing the edge of the extension against the face of the meeting
rail, thus forming a stop which prevents any motion of the locking bar.
In order to render the fastener more secure a groove may be cut in the face of
the meeting rail in which the extension will drop, or a small plate may be secured
furnished with a projecting face or stop against which the extension will bear. The
extension may also be slotted so as to engage with a pin fitted to the meeting rail,
or any other form of stop may be employed.
According to a modified form of fastener the locking bar may be cut or notched
and the securing piece dropped into the notch or recess, or the base may be per-
forated and a pin employed which when the fastener is secured will drop automatically
into the hole, locking the fastener effectually.
In order that the invention may be more clearly understood reference is had
to the accompanying sheet of drawings in which Fig. 1 is a front view, Fig. 2 a
side elevation, Fig. 3 a plan of the fastener constructed according to my invention,
and Fig. 4 shows a modified arrangement.
Referring to Figs. 1, 2 and 3 the meeting rail A of the upper sash is provided
with the usual plate B screwed to it and carrying a pivoted locking arm C furnished
with a spring in the usual manner.
On the extremity of this locking arm a small plate or extension is hinged adapted,
when the arm is turned into locking position, to drop in front of the meeting rail A'.
This meeting rail is provided with the plate D carrying the hook or catch d beneath
which the locking arm is turned.
In the arrangement shown in the drawings, the plate D is furnished with the
extension d' at the front forming a shoulder which prevents the locking arm being
moved back owing to the extension c dropping behind the shoulder. Any other
suitable form of stop may be employed.
In the arrangement shown in Fig. 4, instead of employing a small extension on
the end of the locking arm, the latter is perforated, and a pin E employed adapted
to drop into the perforation when the locking arm or bar is turned into operative
position.
The pin can be easily raised when it is required to open the window, but the
locking bar cannot be operated from the outside.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
(1) A new or improved sash fastener having an extension on the end of the
locking arm or bar adapted to drop in front of the meeting rail, and a stop
preventing the arm being moved back substantially as and for the purposes
specified.
(2) An improved sash fastener having a hinged extension on the end of the
locking arm, and a stop on the front meeting rail substantially as described and
shown in Figs. 1, 2, and 3 of the accompanying drawings.
(3) An improved sash fastener having a perforation or recess in the locking
arm, and a pin or locking piece adapted to drop into the recess substantially as
described and shown in Fig. 4.
