PROVISIONAL SPECIFICATION.
Improvements in Sash Fasteners.
I GEORGE ALEXANDER BREBBER, of Barron Villa, East Coates, Cambuslang,
near Glasgow, Trader in Africa, S.W. do hereby declare the nature of this inven-
tion to be as follows:-
My invention has for its object to provide safe means of locking window sashes,
while at the same time preventing the latter from rattling.
In carrying my invention into practice, I form a circular perforation through
the meeting rails of the lower and upper sashes, in which passes a screw, furnished
outside with a square head, whereby it may be opened or closed, by means of a
removable key. A rectangular bolt is countersunk in the meeting rail of the lower
sash, and is centrally perforated to allow for the passage of the screw aforesaid,
the end of which enters, when the sashes are locked, the perforation of the meeting
rail of the lower sash.
The latter rail is further provided with two openings, one on each side of the
above perforation, to receive the ends of the rectangular bolt aforesaid, against the
back of which bear the inner ends of two springs, fixed at their outer extremities
to the rear end of the recess in which the bolt is sunk.
The screw is devoid of thread on its central part which is moved to and fro, for
locking or unlocking purposes in the central opening of the bolt, whose ends are
bevilled.

Improvements in Sash Fasteners.
I GEORGE ALEXANDER BREBBER, of Barron Villa, East Coates, Cambuslang,
near Glasgow Trader in Africa, S. W. 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 for its object to provide safe means of locking window sashes
while at the same time preventing the latter from rattling.
In carrying my invention into practice, I form a circular perforation through the
meeting rails of the lower and upper sashes, in which passes a screw furnished
outside with a square head whereby it may be opened or closed by means of a
removable key.
A rectangular bolt is countersunk in the meeting rail of the lower sash and is
centrally perforated to allow for the passage of the screw aforesaid, the end of
which enters when the sashes are locked, the perforation of the meeting rail of the
upper sash. The latter rail is further provided with two openings, one on each
side of the above perforation, to receive the ends of the rectangular bolt aforesaid
against the back of which bear the inner ends of two springs fixed at their outer
extremities to the rear end of the recess in which the bolt is sunk.
The screw is devoid of thread on its central part which is moved to and fro for
locking or unlocking purposes, in the central opening of the bolt, whose ends are
bevilled.
The accompanying drawing shows a plan of the meeting rails of the upper and
lower sashes furnished with my improved fastening means.

page_text: S. is the meeting rail of the lower sash and S¹ that of the upper sash. According
to my invention I form a rectangular recess in the top of the rail S¹ in which is
placed a metal lining R. I further form in the front edge of the upper sash S¹³,
three central recesses preferably of circular shape lined with the bushes n. m. P.
which are terminated with flanges d, the bush m being tapped as shown.
rings countersunk in the rear edge of the front sash S'. A recess is similarly
formed in the centre of the front edge of the lower sash S¹, and is lined with a
tapped bush l.
e e are
Against the front wall of the recess R are screwed the ends of the springs a
bearing at their ends against the rectangular bolt b, which is perforated centrally
to allow the smooth part of the rod r to move through the same. This rod is
screw-threaded at both ends and taken into the tapped bushes m, l, being furnished
in front with a square end c whereby it may be turned in either direction for the
purpose of locking or unlocking the sashes S. S¹. g. g are two raised parts against
which the bolt b abuts when shot in position. R' is a cover plate removed for the
purpose of showing the mechanism. By turning with a key the square end c of
the screw-rod r, the same can be withdrawn from the tapped bush m removing
with it the two arms of the bolt 6 from the corresponding bushes n. p. and
depressing the springs a, so that the sashes are now opened as shown in the
drawings. A reverse turn of the key will bring the rear screw threaded end of
the rod into the tapped bush m and the bolt arms into the bushes n. p when the
two sashes are securely locked together.
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 :-
The improved sash fastener, arranged, constructed, and operating, substantially
as herein described and shown.
