COMPLETE SPECIFICATION.
An Improved Sash Fastener.
JOHN FORTUNE PEEBLES 8 Hope Street Lane Edinburgh Cabinet Maker
and Upholsterer 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 consists of an improved sash fastener.
This Specification is accompanied by drawings with letters of reference
corresponding to the several parts.
Figure I is a perspective view of my improved sash fastener with socket complete
to be screwed on top rail of lower sash.
Figure II is a perspective view of my improved sash fastener with socket
complete to be sunk through the top rail of lower sash.
Figure III is a side view of Figure I.
Figure IV is a side view of Figure II in their respective positions.
In accordance with my invention I employ a metal box having a bolt and spiral
spring inside one end of box being open for the action of the bolt. The bottom of
the box projects at the sides having a lid or cover to correspond, this projecting
portion being for screw nail purposes. A portion of the bolt is level with the sides
of the box the remainder being reduced to a suitable thickness the point of this
reduced portion projects through the end of the box a portion being taken out for
that purpose, this projecting portion is formed into a hinge with a corresponding
projection on back of lever bar, Fig. III letter D. Between the thick portion of
the bolt and inside of end of box on the reduced portion of the bolt 1 employ a
spiral spring which presses the bolt into the socket. There is a pin through the
thick portion of the bolt with corresponding slotholes in sides of box as shown
Fig. III letter A which determines the distance the bolt passes into the socket the
LD
,,

page_text: distance between the pin of the hinge and the point of lever bar being sufficient
to withdraw the bolt from the socket. This improved sash fastener is made to be
screwed on top rail of lower sash and to project a sufficient distance over the lower
rail of upper sash to prevent the insertion of any instrument to push back the bolt.
The socket which is screwed on lower rail of upper sash is solid except the space
for the bolt.
My improved sash fastener to be sunk through the top rail of lower sash with
socket sunk into lower rail of upper sash is exactly the same in all material parts
as already described the end of box at lever bar and front plate of socket project at
sides for screw nail purposes Fig. II letters E there being no lid or cover to the
box, I employ a metal plate having a space for end of box which is sunk into t
outer edge of lower sash as shown Fig. IV letter B to resist the upward pressure of
the bolt when the windows are being closed, this metal plate and the plate of the
socket are sunk not to the level of the sash rails but perpendicular as shown
Fig. IV letter C which prevents the insertion of any instrument to push back the
bolt there is a pin of sufficient length fixed into the checked end of the bolt and
passes through the spiral spring to keep it in position Fig. I letter F.
Having now particularly described the nature of my invention and in what
manner the same is to be performed, I declare that what I claim is
The method of withdrawing the bolt from the socket by means of the lever har
