PROVISIONAL SPECIFICATION.
Improvements in Sash Fasteners.
I, JOSEPH GORDON of Layfield Street, Burnley, in the County of Lancaster,
Locksmith, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a cheap and simple sash fastner,
which cannot be picked by the introduction of implements between the window
sashes, and which in addition to this essential feature will possess more advantages
than other fastners in common use.
In constructing my improved fastner, I fix to the lower window sash a casing
running transversely of the sash, and provided with a longitudinal slit. Through
this slit protrudes a knob, fixed at one end of a bar, provided with a catch at its
other end, and sliding on a pin, and which, in order to steady it, preferably passes
through a longitudinal slot formed in the bar. A blade spring is attached to the
upper end of the casing, and bears upon the sliding bar, in such a manner as to
depress the sliding bar at its knob end, so that when the bar is shot forward, the
catch at the other extremity of the bar will engage with a loop or staple, fixed to
the upper window sash.
To unfasten the window, it is simply requisite to raise the knob, when the catch
will be withdrawn from the loop or staple, and the bar is then slid backwards.
In order to still further add to the security of the fastner, and to prevent any
possibility of the window rattling, an adjusting screw or nut may screw into a hole
formed in the outer extremity of the sliding bar, which, when tightened, will draw
the catch firmly against the loop or staple, and so bind the sashes together.

COMPLETE SPECIFICATION.
Improvements in Sash Fasteners.
I, JOSEPH GORDON of Layfield Street, Burnley, in the County of Lancaster,
Locksmith, 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 :-
The object of this invention is to provide a cheap and simple sash fastener, which
cannot be picked by the introduction of implements between the window sashes,
and which in addition to this essential feature will possess more advantages than
other fasteners in common use.
In constructing my improved fastener, I fix to the lower window sash a casing
running transversely of the sash, and provided with a longitudinal slit. Through
this slit protrudes a knob, fixed at one end of a bar, provided with a catch at its
other end, and sliding on a pin, and which, in order to steady it, preferably passes
through a longitudinal slit formed in the bar. A blade spring is attached to the
upper end of the casing, and bears upon the sliding bar, in such a manner as to
depress the sliding bar at its knob end, so that when the bar is shot forward, the
catch at the other extremity of the bar will engage with a loop or staple, fixed to
the upper window sash.
To unfasten the window it is simply requisite to raise the knob, when the catch
will be withdrawn from the loop or staple, and the bar is then slid backwards.

page_text: In order to still further add to the security of the fastener, and to prevent any
possibility of the window rattling, an adjusting screw or nut may screw into a hole
formed in the outer extremity of the sliding bar, which, when tightened, will draw
the catch firmly against the loop or staple, and so bind the sashes together.
In the accompanying drawings,
Fig. 1 is a detached view of a window sash, with my improved sash fastener
applied.
A is a metal casing fixed to the lower window sash B, and provided with a
longitudinal slot C, in which slides the knob D of the sliding bar E. The latter
is preferably provided with a side slot F, and is acted upon by the spring G at its
knob end, in such a manner that when the sliding bolt or bar E is slid forward on
the stationary pin F1, it will be depressed at its knob end, whilst its other snecked
or catch end H will rise and engage with the upper portion of the loop or staple I
fixed to the upper window sash J, thereby firmly fastening the two sashes
together.
When it is desired to unfasten the window, all that is requisite is to raise the
knob D, when the catch H will be withdrawn from the loop or staple I, and the
sliding bar is free to be moved backwards, thus unfastening the window.
In Fig. 2, the sash fastener is represented as having a screw K and thumb nut L,
so that when the bar E is slid forward, and its catch end H engages with the
loop or staple I on the upper window sash, the thumb nut L may be tightened, and
thereby still further add to the security of the fastener.
Fig. 3 represents a modification of my invention, in which view the catch or
snecked end H of the sliding bar is shewn as being formed at the side whilst both
the pin F and slot F are vertical. In this arrangement instead of having the
additional locking device shewn in the preceding figure, the fastener may be con-
veniently locked by forming the recess M at the far extremity of the longitudinal
slot C of the metal casing A, so that when the bar is shot forward and the catch
or snecked end H engages with the loop or staple I, the shank of the knob D
will fall into the recess M by the pressure of the spring G, and thus securely
fasten the sashes. In some cases, the spring may be dispensed with, and the knob,
when the bar is shot forward, may be turned down into a recess at the side of the
casing A.
Fig. 4 represents another modified form of my invention, wherein I employ two
sliding bars P, which cross each other, and are secured at their junction by the
stud or pin F, which slides in the longitudinal slot C. The bars are each
provided with catches H at one end and knobs D at the other respectively. The
catches H, expanding by the pressure of the V shaped spring G, engage with the
loop or staple I when the slide bar is shot. To unfasten the window the catch or
snecked ends H are closed by pressing the knobs D after the manner of a pair of
scissors, and bringing the bar back to its former position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
⚫ claim is :-
1. The construction and arrangement of a sash fastener, substantially as
described and illustrated in Fig. 1.
2. Sliding bar E carrying catch H and acted upon by spring G, as to raise the
said catch H when the bar is shot forward on the pin F1 working in slot F,
substantially as described, and illustrated for the purpose set forth.
3. Screw K and thumb nut L for locking the sashes after the bar has been shot
forward, substantially as described, and illustrated in Fig. 2.
3. The construction and arrangement of sash fastener provided with catch H
at the side and recess M in the casing A for simultaneously fastening and locking
the window sashes, substantially as described and illustrated in Fig. 3.
4. My improved arrangement of sash fastener, substantially as described, and
illustrated in Fig. 4.

described and illustrated in all the figures.
