Improvements in Sash Fasteners.
I, WILLIAM FLETCHER of 14, Northcote Terrace, Kirkewhite Street, Notting-
ham Machine Fitter, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improveed fastening for window sashes.
In the inner sash meeting rail is let a metal box carrying a key. The handle
of the key projects into the room and the other end of the key is furnished with
a bevelled ward and is capable of being placed into counter-sunk eye or recess
formed for it in a plate screwed to the inner face of the outer sash. A spring is
placed inside the key-box tending to push the key towards the outer sash. When
the key is drawn back so that the ward comes inside the box it is turned round
a little and the key is then retained in such a position that the sashes may be
freely moved. When the window is to be fastened the key is passed into the
countersunk hole in the plate fixed to the top sash meeting rail; the action of
the spring carries the key into this hole when the latter it turned rightly. After
the ward has passed through the hole in the outer sash the key is turned slightly
and this action draws the sashes together. For additional security in exceptional
cases a small hole is provided in the top of the plate on the outer sash which
admits of a detachable pin being passed down in front of the portion of the hole
through which the key ward passes, so that the key cannot be withdrawn until
this said pin is removed. This improved fastener may be formed of brass, iron
or other suitable metal.
I, WILLIAM FLETCHER of 14, Northcote Terrace, Kirkewhite Street, Notting-
ham, Machine Fitter, 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 key is drawn back so that the ward comes inside the box it is turned round

freely moved. When the window is to be fastened the key is passed into the
counter-sunk hole in the plate fixed to the top sash meeting rail; the action of
the spring carries the key into this hole when the latter is turned rightly. After
the ward has passed through the hole in the outer sash the key is turned slightly

admits of a detachable pin being passed down in front of the portion of the hole
through which the key ward passes, so that the key cannot be withdrawn until
this said pin is removed.
In order. that. the invention may be more clearly understood, reference is had to
the accompanying sheet of. drawings in which Fig 1 is a section of my improved
fastener, and Figs 2 and 3 show elevation and plan respectively of the plate on
the upper sash.
The box or case A is fitted to the meeting-rail B of the lower sash and is pro-
vided with the bolt or key C passing through a perforation in the side a of the
case. This bolt is formed with the head C by which the fastener is operated
and around this bolt the spiral spring D is fitted which tends to push the bolt
through another opening in the back a¹ of the case.
To prevent the bolt being pulled back too far, and also to secure the spring,
the stop c¹ is provided.
The perforation in the back a¹ of the case is adapted to receive the end of the
bolt and also to allow the ward c² to pass through so as to engage with a plate of
metal fitted to the upper sash meeting-rail F. which is also provided with a
similarly shaped perforation e.
As shown in Fig 2 the edges of the hole e in the plate E are bevelled so as to
cause the ward. ² to bear against the latter and draw the sashes together to
prevent rattling and in order to prevent any accidental unlocking of the fastener
1 provide a small pin G fitting into a perforation el in the thickness of the plate E
which prevents the ward from turning into the unlocking position.
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) Improvements in sash fasteners consisting in having a case fitted to the
meeting-rail of the lower sash and provided with a bolt having a knob at one
end and a ward at the other which engages with a plate on the meeting-rail
substantially as described and shown and for the purposes specified.
(2) In sash fasteners the combination with the bolt C, spring D, stop c¹ and
ward of the plate E bevelled hole and the pin e¹ substantially as described
and for the purposes specified.
