Improvements in Sash Fasteners for Windows.
I, JOHN WALSH, of 36, Stanhill Lane, Oswaldtwistle, in the County of Lancaster,
Sawyer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved form of window sash fastener, the object
being to construct a fastener which will securely fasten the two window frames
tightly together, thus preventing draughts of air and shaking or rattling, and also
preventing the insertion of knives or other instruments for the purpose of opening
the window from the outside.
According to this invention, I screw a bracket having two sides on the top frame
of the lower window, this bracket carries an eccentric and lever or handle work-
ing on a pin between the sides of the bracket. The eccentric is fitted with a strap
or ring having a curved or hooked shaped projecting piece, which passes under
a guide between the two sides of the bracket and engages with a loop shaped
bracket screwed on the lower frame of the top window.
The action is as follows:-To unfasten the window the before mentioned lever
or handle on the eccentric is pulled, and this causes the eccentric block to travel
round the top side of the pin and draw the hook or curved projecting piece out
of the loop. To fasten the window the lever or handle is pressed in the opposite
direction, and this causes the eccentric block to first travel in a downward direction
towards the loop and the curved projecting piece is inserted into the loop shaped
bracket. A further depression of the lever causes the eccentric block to travel
still in a downward direction away from the looped bracket and this causes the
under side of the hooked projecting piece to be pressed against the bottom of the
bracket and drawn up an incline thereon, thus raising the point of the hook or
looped projecting piece and causing it to engage with the top of the loop shaped
bracket, and so to draw and hold the two window frames tightly together.

Improvements in Sash Fasteners for Windows.
I, JOHN WALSH, of 36, Stanhill Lane, Oswaldtwistle, in the County of Lancaster,
Sawyer, 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 an improved form of window sash fastener, the object
being to construct a fastener, which will securely fasten the two window frames

page_text: tightly together, thus preventing draughts of air and shaking or rattling, and also
preventing the insertion of knives or other instruments for the purpose of opening
the window from the outside.
Such being the nature and object of my said invention, the following is a com-
plete description of same, reference being had to the annexed drawings, in
which: :-
Fig. 1 is a sectional side elevation of the improved sash fastener closed or lock-
ing the window sashes.
Fig. 2 is a side elevation of the improved sash fastener open.
Fig. 3 is a plan view of Fig. 2.
According to this invention, I screw a bracket 1, having two lugs or sides 2, 2,
on the top frame 3 of the lower window, this bracket 1 carries an eccentric 5 and
lever or handle 6 working on the pin 4 between the sides or lugs 2-2 of the
bracket 1. The eccentric 5 is fitted with a strap or ring 7 having a curved or
hooked shaped projecting piece 8 which passes under a guide 9 between the two
sides or lugs 2-2 of the bracket 1 and engages with a loop shaped bracket 10
screwed on the lower frame 11 of the top window.
The action is as follows:-To unfasten the window, the before mentioned lever
or handle 6 on the eccentric 5 is pulled, and this causes the eccentric block 5' to
travel round the top side of the pin 4 and draw the hook or curved projecting
piece 8 out of the loop 10. To fasten the window, the lever or handle 6 is pressed
in the opposite direction, and this causes the eccentric block 5 to first. travel in a
downward direction towards the loop 10 and the curved projecting piece 8 is
inserted into the loop shaped bracket 10. A further depression of the lever causes
the eccentric block 5 to travel still in a downward direction away from the looped
bracket 10, and this causes the under side of the hooked projecting piece 8 to be
pressed against the bottom of the bracket 1 and drawn up an incline thereon, thus
raising the point of the hook or looped projecting piece 8 and causing it to engage
with the top of the loop shaped bracket 10, and so to draw and hold the two
window frames 3 and 11 tightly together.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1
(1) The general construction, arrangement, and combination of parts con-
stituting the improved sash fastener, as and for the purpose herein described and
substantially as illustrated by the annexed drawings.
(2) A sash fastener wherein the hook or curved projection 8 is mounted on and
operated by an eccentric forming part of which is a handle or lever 6, all in com-
bination as and for the purpose herein described and substantially as illustrated
by the annexed drawings.
