PROVISIONAL SPECIFICATION.
Improved Window-sash Fastener..
GEORGE SPENCER 87 Market Street Hyde Cheshire Watchmaker do hereby
declare the nature of this invention to be as follows:-
:-
A window-sash fastener which also allows the window to be open a short distance.
and still be secure from being opened from the outside. This window-sash fastener
consists of two parts, one part to be attached to the upper sash and the other to
the lower sash. The part attached to the upper sash is a piece of metal five inches
long in. wide and has a slot down the centre 3 in. long by wide, this metal
plate is screwed to one of the uprights of the sash.
The other parts consists of a small metal bolt with a stop fitted in it to prevent
the bolt being pushed back from outside of window.
The stop is a piece of metal 1 inch long by deep by thick with a projection
on the top, it has also a slot through, and when in its place a pin is fitted through
this slot. When the bolt is pushed out and the stop is put down the bolt cannot
be pushed back.
To allow the bolt to be pushed back the stop would have to be lifted up and
while so held it must be turned over then the bolt can be moved back.
The bolt part is screwed on the top of lower sash at the corner so that when the
bolt is pushed out it will come immediately under the plate screwed on upper sash,
and when the sash is open a little the bolt can be pushed in the slot and the stop-
put down the window is then secure.
