JOHN HENRY EDWARDS, 6, Glenparke Road, Forest Gate, E, Commercial
Traveller, do hereby declare the nature of this invention to be as follows:-
In making this window fastener I affix to the upper sash a metal device or case
with open front upright sides and grooved back. In this device I pivot or other-
wise secure a metal bar with a projection or lip at its lower end turned toward
the lower sash.
There is also a lip on the lower end of bar at the back and turned toward the
back of device.
I also provide a heavy piece of metal the required shape to work easily up and
down in the grooved back of fastener which acts as a stop or wedge on the bar
when released by the lip.
On the edge of lower or inner sash I affix a metal device with a projection or
lip pivotted or otherwise secured and overhanging the upper sash far enough to
strike the lip on bar.
Having described the construction and position of this fastener, it will be
readily seen that, when the window is being closed, the lip on the lower sash
comes in contact with the lip on bar, it forces the lip down turning the bar
inward and over the device on lower sash;
At the same time the lip on back of the bar releases the metal stop or wedge in
the grooved back of fastener, which then drops down behind the bar thus keeping
it firm and secure.
To open the window it is only necessary to raise the metal stop again, and the bar
to a perpendicular position which is retained by the stop resting on the the back
lip of bar.

I, JOHN HENRY EDWARDS, 6, Glenparke Road, Forest Gate, Commercial
Traveller, 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;-
In making this window fastener I affix to the upper sash a metal device or case
with open front, upright sides, and grooved back. In this device I pivot or other-
wise secure a metal bar with a projection or lip at its lower end turned toward
.

page_text: the lower sash; there is also a lip on the lower end of bar at the back, and turned
toward back of device. I also provide a heavy piece of metal the required shape
to work easily up and down in the grooved back of the fastener, which acts as a
stop or wedge on the bar when released by the lip. On the edge of lower or inner
sash I fix a metal device with a projection or lip pivoted or otherwise secured, and
overhanging the upper sash far enough to strike the lip on bar.
Having described the construction, and position of this fastener it will be
readily seen that when the window is being closed. the lip on the lower sash
comes in contact with the lip on bar, it forces the lip down turning the bar inward,
and over the device on lower sash at the same time the lip on back of the bar
releases the metal stop or wedge in the grooved back of fastener which then drops
down behind the bar thus keeping it firm and secure.
To open the window it is only necessary to raise the metal stop again, and the bar
to a perpendicular position which is retained by the stop resting on the back lip
of bar.
For purposes of illustration I will now refer to the annexed drawings in
which:-
Figure is a sectional elevation shewing my fastener in its open position.
Figure 2, side elevation shewing same when closed or locked.
Figure 3, side elevation shewing bolt in course of opening or locking.
The bolt or tumbler a is pivoted at to the casing c, and is shaped as shewn
having beaks or projection d & e. The plate f is secured to the sash g, and the
projection or beak upon same when coming into contact with the projection d
on the bolt or tumbler a causes the same to turn upon the pivot band to assume
the position shewn in Figure 2 thus locking the sashes. The weight slides in
the casing and it will be seen that when in the position shewn in Figure 2 the
bolt or tumbler a cannot be raised to its perpendicular position until the weight
has been raised. The action of turning the bolt or tumbler into its locking position
will raise the weight until the beak e passes from under it, when the weight will
fall into position so as to lock the bolt or tumbler a.
Although I have described my invention as applied to window fasteners, it
will be understood that there are other uses to which the fastener can be put.
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. In window fasteners of the class herein described, the combined construction
and arrangement of the various parts substantially as described, and illustrated
herein, and for the purpose set forth.
2. In window fasteners, a pivoted bolt or tumbler carried in a suitable casing,
and being secured in its locking position by means of a sliding weight said bolt
or tumbler having a projection upon which a beak or lip upon a plate fixed to
one of the sashes engages for the purpose of bringing the bolt or tumbler into its
locking position; and another projection upon said bolt or tumbler for the purpose
of raising the locking weight when required, substantially as described, and illus-
trated herein, and for the purpose set forth.
