Improvements in Sash Fasteners.
1, DAVID WALLER the younger, of No. 81 Church Street Croydon in the
County of Surrey, Builder and Decorator, do hereby declare the nature of this
invention to be as follows:-
My invention has reference to fasteners for the sashes of windows and the like,
whether they be sliding, hinged or pivotted.
The fastener consists of a screw, bolt or other fastening which is mounted in a
nut or barrel screwed or otherwise fixed to one of the sashes or other part, and of
a support, having one, two or more holes or recesses, which is fixed to the other
sash or corresponding part in such manner that if for instance the sashes are
intended to be secured in the closed position, the end of the screw is made to take
into the lower hole or recess in the support on the other sash thus securely locking
the two sashes together. If it be desired to leave the window slightly open the
screw or bolt is released from the said lower hole or recess the upper sash is
lowered or the lower sash is raised and the end of the screw is made to enter a
recess higher up in the support and so on. The tendency of the fastening when
in action is to cause the two sashes to be as wide apart as the beading and outside
lining of the sash frame will allow. If the fastening be at an inconvenient height
from the floor the screw or bolt may be provided with a pulley. and an endless cord
or the like so as to permit of screwing and unscrewing the screw in order to make
it take into the desired recess in the support and to be removed therefrom as
required. The fastening may conveniently be used in connection with the false
rails which are used to fill up the space between the lower sash and the sill of the
sash frame whereby the desired ventilation is obtained between the two sashes
while security against the window being opened from the outside is ensured. In
any case the fastening cannot be tampered with from the outside whether the
window be open or closed and the sashes are prevented from rattling.

I, DAVID WALLER the younger of No. 81 Church Street, Croydon, in the
County of Surrey Builder and Decorator 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:-
My invention has reference to fasteners for the sashes of windows and
the like.
Fig. 1 of the accompanying drawing is a side view of a sash fastener constructed
according to this invention and adapted to ordinary sliding window sashes,
Fig. 2 is a front view, Fig. 3 a sectional side view and Fig. 4 a plan.

page_text: The fastener consists of a screw C which is mounted in a, nut B or barrel
screwed or otherwise fixed to the inner sash D (or other part), and of a support
bracket or standard A having one or more holes or recesses, in this case three
recesses A¹, this support or bracket being fixed to the other sash E or corre-
sponding part in such manner that if for instance the sashes are intended to be
secured in the closed position, the end of the screw C is made to take into the
lowest recess A' in the bracket A on the other sash E thus securely locking the
two sashes D and E together and keeping them from rattling. Instead of a
screw C, a bolt with a projecting lug may be used which works in a socket
provided with a bayonet joint groove and fixed on the sash D.
If it be desired to leave the window slightly open, for the sake of ventilation,
the screw C is released from the said lower recess or hole A' and the upper sash E
may then be lowered, or the lower sash D raised so far that the end of the
screw C is made to enter a recess A¹ higher up in the bracket. Instead of the
recesses A¹ I may have a vertical groove in the bracket A, but that would not
afford much security against the sashes being moved and the window opened
surreptitiously from without. The tendency of the fastening when in action is to
cause the two sashes to be as widely apart as the clearance at the beading and
outside lining of the sash frame will allow.
If the fastener be at an inconvenient height from the floor the screw or bolt C
may be provided with a pulley and an endless cord or the like so as to permit of
screwing and unscrewing the screw in order to make it take into the desired
recess A in the bracket A and to be removed therefrom as required.
The bracket A may be made to hinge to one side upon its base part, as shown
in the front view Fig. 5 and side view Fig. 6 when the upper part can fold down
laterally in the direction of the arrow or the upper part of the bracket may as
shown in the front view Fig. 7 and side view Fig. 8 be hinged to the lower part
of same and fold down in the direction of the arrow towards the inside of
the room.
The fastener may conveniently be used in connection with the false rails which
are used to fill up or cover the space between the lower sash and the sill of the
sash frame, whereby the desired ventilation is obtained without unpleasant draught
while security against the window being opened from the outside is secured. Ia
any case the fastener cannot be tampered with from the outside, whether the
window is closed or somewhat open, and the sashes are prevented from rattling.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A sash fastener consisting of a standard or bracket fixed to the upper sash,
and a screw or bolt applied to a nut or barrel on the lower sash in such manner
that the said screw or bolt can be brought to bear against the bracket thus
tending to force the two sashes apart and keep them from rattling whether closed
or partly open substantially as set forth.
2. The safety sash fastener as described with reference to the drawings.
