Improvements in Fastenings for Window Sashes or the like.

I GEORGE ALANSON MASON of 109 Farringdon Road in the County of Middlesex
Electrical Engineer do hereby declare the nature of this Invention to be as follows:-
This Invention relates to fastenings for window sashes or the like designed to be
fixed to the meeting bars or parts to be secured together and it has for its object to
provide a fastening the parts of which automatically engage when the sashes or the
like are closed and can readily be released from the inside (but not from the outside)
to open the sashes or the like. I will describe the Invention as applied to a window
sash from which its application to like purposes to which it is or may be applicable
will be readily understood. One of the meeting bars of the sash is provided with a
part which by means of a spring or its equivalent tends always to its closed and
fastened position in which position there is engaged with it a part on the other bar of
the sash so as to fasten the parts of the sash together the shutting of the window
causing the automatic engagement of the parts. I prefer to make the one part of the
fastening of a standard or standards with a cross piece there between or a projection
therefrom and the other part of an upright behind which the said cross piece or
projection passes when the sashes are closed. Behind this upright is a lever pressed
forward by a spring or the like so as to bear on the upper part of the said upright
and so secure the aforesaid cross piece or projection and prevent the sashes from being
raised until the lever is pressed back. The meeting faces of the upright and cross
piece or projection or one of them is or are inclined or bevelled to cause a wedging
action so as to draw the sashes together and make a tight closure.

Improvements in Fastenings for Window Sashes or the like.
I GEORGE ALANSON MASON of 109 Farringdon Road in the County of Middlesex
do hereby declare the nature of this Invention (which Invention has been communi-
cated to me by George Francis Shaw of Dedham in the County of Norfolk and
State of Massachusetts in the United States of America) 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 fastenings for window sashes or the like designed to be
fixed to the meeting bars or parts to be secured together and it has for its object to
provide a fastening the parts of which automatically engage when the sashes or the
like are closed and can readily be released from the inside but not from the outside
to open the sashes or the like. I will describe the invention with reference to the
accompanying drawing which represents it as applied to a window sash from which
its application to like purposes to which it is or may be applicable will be readily
understood. Figures 1, 2 and 3 represent respectively in front elevation side elevation
and plan the improved fastening with the window in its closed position and Figure 4
is a transverse section of the same. Figure 5 is a perspective view of one part of the
said fastening detached and Figure 6 is a similar view of the other part of the said
fastening. One of the meeting bars A B of the sash are respectively provided with
the parts CD of the fastening one of which parts viz. D is provided with a Lever F
acted upon by a spring E or its equivalent which tends always to force it into its
closed and fastened position in which position it is engaged with the part C on the
other bar A of the sash and thus securely fastens the two parts A B of the sash
together the shutting of the window causing the automatic engagement of the
parts C&D. The part C of the fastening as shewn consists of a standard or
standards c c connected by a cross piece c² there between or it may be a projection
therefrom and the other part D consists of an upright behind which the said cross
piece or projection passes when the sashes A B are closed. Behind this upright is
the lever F pressed forward by the spring E or the like so as to bear on the upper
part of the said upright d and so secure the aforesaid cross piece c² or projection and
prevent the sashes from being raised until the lever is pressed back. The meeting
faces of the upright d and the cross piece c² or projection or one of them is or are
inclined or bevelled to cause a wedging action so as to draw the sashes together and
make a tight closure in the act of closing the sashes.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed I declare that what I claim is
:
First In fastenings for window sashes or the like―The combination of the bar
or projection ³ on one of the closing bars of the sash and the lever F carried by the

page_text: other closing bar of the sash and arranged to engage with the projection c² automatically
when closing the window substantially as hereinbefore described and illustrated by the
accompanying drawings.
Second-In fastenings for window sashes or the like, the inclined projections c²
and d for drawing the two parts of the sash into close contact when closing the
window in combination with the lever F or its equivalent acted upon by a spring or
the like for securing the window in its closed position substantially as hereinbefore
described and illustrated by the accompanying drawings.
Third A sash fastener consisting of a part which by means of a spring in its
equivalent tends always to return to its closed and fastened position in which position
it engages with or against the other part of the fastener so as to fasten the two parts
of the sash together substantially in the manner herein before described and illustrated
by the accompanying drawings.
