'I,'CHARLES JOHN BROOKE, of 66, Lancaster Avenue, Manchester, in the County
of Lancaster, Indigo Merchant, do hereby declare the nature of this invention to
be as follows:-
.1
This invention relates to fasteners for window sashes: the objects of: my invention
are to afford increased security against burglary by preventing the fastener being
feloneously opened from the outside of the window, and to close more effectually
the upper and lower sashes by drawing them together for the exclusion of draught
and to prevent rattling in windy weather. The accompanying drawing to which
I hereinafter refer represents a plan view of a window sash fastener, according to
this my invention.
'I construct a sash fastener by connecting a metallic hoop or bow as 'b: that is
formed to swivel on a base as a which is permanently attached to the 'bottom
frame c of the outer sash: Ifit on the top framed of the.inner sash a correspond-
ing base as a that is formed with a vertical projection e placed in a position
that will permit the aforesaid hoop b to be passed over, and lie down on the outside
of the projection c. I form the loop b with a screwed. boss f: through which .to
pass a set screw or thumb screw asg. When both the sashes. of.a window are
closed the aforesaid hoop. or bow b.is placed down over the projection.e.and.the
thumb or set screwg. is screwed up tightly against the projection.e. By these
means-the-two-window-sashes are drawn close together. thereby excluding draught
and preventing rattling in windy weather, and the window cannot be feloneously
opened from the outside by the insertion of a knife or other' tool.

Improvements in Fasteners for Window Sashes.
I, CHARLES JOHN BROOKE, of 66, Lancaster Avenue, Manchester, in the County
of Lancaster, Indigo Merchant, 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 fasteners for window sashes; the objects of my invention
are to afford increased security against burglary by preventing the fastener being

page_text: feloniously opened from the outside of the window, and to close more effectually
the upper and lower sashes by drawing them together for the exclusion of draught
and to prevent rattling in windy weather. I attain these objects by the means
hereinafter described, reference being made to the accompanying sheet of drawings
in which Fig. 1 is front view of part of a window sash with my improved fastener
applied. Fig. 2 is vertical section of window sash showing end view of said
fastener; in these views the fastener is represented as being open and the sash
unsecured. Fig. 3 is a plan and Fig. 4 an end view representing said fastener closed
and the window sash thereby secured; Fig. 5 is a modification of the same inven-
tion; corresponding letters in each view refer to corresponding parts.
I construct a sash fastener by connecting a metallic hoop or bow as c that is
fitted so as to swivel on a vertical projection b formed on a base as d which is
permanently attached to the bottom frame a of the outer sash: I fit on the top
frame a' of the inner sash a base as d' that is formed with a corresponding vertical
projection e placed in a position that will permit the aforesaid hoop c to be passed
over and lie down on the outside of the projection e as in Fig. 4: I form the
hoop o with a screwed boss of through which to pass a set screw or thumb screw
as g. When both sashes of a window are closed as shown on the drawing, the
aforesaid hoop or bow c is placed down over the projection e and the thumb or
set screw is screwed up tightly against the projection c. By these means
the two window sashes are drawn close together thereby excluding draught and
preventing rattling in windy weather, and the window cannot be feloniously
opened from the outside by the insertion of a knife or other tool. In the modifica
tion shown in Fig. 5 the bow c is extended so that the boss f may fall in front
of the top bar a and the screw g to set up against the front of said frame.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1st. A fastener for a window sash constructed with a hoop or bow that is
connected to the bottom frame of the top window sash and formed to swivel so
that said hoop or bow may pass over and lie down on a projection attached to
the top frame of the lower window sash or at the front of said top frame, and may
be affixed thereto by a thumb or set screw and draw the two frames together
substantially as and for the purpose herein before described.
2nd. A window sash fastener constructed with a swivel hoop or bow as c, a set
screw as g and fixed projections as e and b substantially.as and for the purpose
herein before described,
