of this invention to be as follows :-

receives the catch bar or sash fastener, on the inner sash; and also in combination,
and is carried out in the following manner.

A recess is cut in the plate above referred to, of sufficient length and width to
receive an angle piece, & to allow it when pivotted at its junction to move backwards
& forwards, for the purpose hereinafter described.
At a convenient part of the said plate, at the end of same, at the back of the recess, a
small bolt is provided working in a barrel, containing a spring!

The working is as follows When the window is required to be fastened, the catch
bar is pulled over until it comes in contact with the aforesaid angle piece, the said angle
piece being in this position ; on pressing this catch still forward against the said
angle piece, this said angle piece presses against the aforesaid bolt, which is 'forced
back, and enables the angle piece to turn over thus & when it has come to this
position the pressure against tlie bolt is conséquently released and it shoots forward
again in its normal position, and locks the catch bar, which cannot be released

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:-
My invention consists in constructing a window sash fastener which shall give
greater security to windows than those fasteners now in use. This invention is
substantially contained in the arrangement of the plate which receives the catch bar
or sash fastener, on the inner sash; and also in combination, and is carried out in the
following manner.
A recess is cut in the plate above referred to, of sufficient length and width to
receive an angle piece, and to allow it when pivotted at its junction to move backwards
and forwards, for the purpose hereinafter described.
At a convenient part of the said plate, at the end of same, at the back of the recess,
a small bolt is provided working in a barrel containing a spring.
The working is as follows. When the window is required to be fastened, the catch
bar is pulled over until it comes in contact with the aforesaid angle piece, the said
angle piece being in this position L, on pressing this catch still forward against the said
angle piece, this said angle piece presses against the aforesaid bolt, which is forced
back and enables the angle piece to turn over thus and when it has come to this
position the pressure against the bolt is consequently released and it shoots forward
again in its normal position, and locks the catch bar, which cannot be released until
the said bolt is pulled back. It will thus be understood that the window can only be
opened from the inside.
One end of the said angle piece, nearest to the bolt may be bevelled; a portion of
the catch bar may also be bevelled.
In order to enable the invention to be fully understood, I will proceed to describe
the same by reference to the accompanying drawings.

Fig. 2. shows complete window fastener with catch bar unlocked.
Fig. 3. shows end view of catch bar locked.
