I, JOSEPH WHARFE 21 Wandle Road Merton Road South Wimbledon
Engineer 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 a fastener for windows and the same is carried out as
follows.
I provide a pivoted or jointed bolt which slides in a socket carried on a base plate
or support which is secured to the lower sash by screws or the like. The locking
end of the bolt engages in an aperture or hole in a small plate, which is secured to
the upper sash. When the bolt is in its locked position, the two parts are in a
straight line and the pivot or joint is a certain distance in the socket.
A small pin or catch piece is attached to the socket and drops into a small hole
or recess in the bolt and so locks it in position. A small angle piece or stop is
attached to the frame of the window and engages on the handle part of the bolt
and so prevents the lower sash from being raised.
When the bolt is in its unlocked position the handle part can be turned from
engaging with the angle or stop piece into a position about at right angles with the
part of the bolt in the socket.
In order that my invention may be fully understood I now refer to the annexed
drawings in which :-
Figure 1. is a sectional plan view of my invention.

the amount of novement of the bolt being controlled by a pin d attached to same
& which slides in a groove or slot in the socket c. The socket piece c is secured
to the lower sash frame e by means of screws f g is a small plate which is secured
to the upper sash by means of screws or the like and into which the end i of the
bolt engages when it is in its locked' position. ¿¡ is a small angle piece or stop which
is secured to the frame of the window and engages on the part a when the bolt is
in its locked position. I is a movable pin or catch piece which drops into a hole or
recess formed in the bolt and locks it in position. When the bolt has been with-
drawn from-engaging in the plate g the part a may be turned into the position
shown by the dotted lines in Figure 2 m being a knob or handle attached to the
part a.
A sufficient number of plates g may be employed so that the top sash / may be
lowered the required distance, and owing to the bottom sash being secured the two
sashes are secured together in the desired position.
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 :-
1. The combination and arrangement of the various parts substantially as.
described and illustrated.
2. In fastenings for windows, a locking bolt consisting of two parts hinged or
pivoted together & working in a socket attached to one sash one end engaging in-
a perforation or hole in a plate attached to the other sash, the other end having a
handle or knob, a catch piece or pin on said socket for engaging in a recess or hole
in said bolt, when in its locked position, said bolt being controlled by a pin attached
thereto & working in a slot or groove in said socket, a stop piece or catch secured
to the frame of the window and engaging on the handle end of the bolt when same
is in its locked position substantially as described & illustrated.
