CHARLOTTE RUSSOм, 32, Cooper Street, Meanwood Road, Leeds, do hereby
declare the nature of this invention to be as follows:
The object of this invention is to obtain a reliable automatic lockfast window-
fastener. To obtain this I employ the frame and mechinism of an ordinary.
window latch or fastener, one portion of which is fixed on the front sash, and the
other portion on the back sash. The latch being opened and closed in the usual
manner. With this exception that the knob is loose in a socket on the end of the
latch, the knob is held down by a spring on the spindle of the knob, when the
window is fastened the end of the spindle drops into an opening in the bed plate,
and thereby the latch is held fast. On opening the latch the knob is raised and
pushed back in the usual manner, in so doing this action turns, the knob and
spindle round, there being a notch on the top of the socket, and a pin on the top
of the spindle knob, thereby suspending the action of the spring and keeping the
spindle end from being in contact with the bed plate, while the fastener is open.
On closing the fastener the reverse action brings the spindle end into position
again dropping into the opening in bed plate.

CHARLOTTE RUSSOм, 32, Cooper Street, now 18, Rowland Road, Dewsbury Road,
Leeds, 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 the method of and means employed of producing a
reliable automatic lockfast window fastener. To obtain this I employ an ordinary
window latch or fastener. And as in the ordinary way the back part is fixed to
the outside sash, and the front part fixed to the inside sash of the window in
the ordinary way except that I employ a loose knob, and form a socket on the
end of the latch lever. Inside this socket is a space for a spring, which acts
upon the spindle on the collar part, between the top of socket and collar upon
the spindle.
The object of this invention is to obtain a reliable window fastener. To obtain
this I employ the frame and mechinism of an ordinary window latch or fastener.

The latch being opened and closed in the usual manner. With this exception
that the knob is loose in a socket Fig. 2 on the end of the latch. The knob is
held down by a spring C, on the spindle D. When the window is fastened the
end of the spindle drop into an opening E in bedplate, and thereby the latch
is held fast. On opening the latch the knob is raised and puslied back in the
usual manner in so doing this action turns the knob and spindle round, there
being a notch on the top of the socket, thereby suspending the action of the
spring and keeping the spindle end from being in contact with the bed plate,
while the fastener is open. On closing the fastener the reverse action brings
the spindle end into position again, dropping into the opening in bed plate,
thereby fastening the arm.
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:-
The method of fixing the latch lever or arm into or upon the bed plate, as
illustrated by annexed drawing.
