PROVISIONAL SPECIFICATION.
A New or Improved Window Fastener.
I, ALBERT ERNEST ROSE, of No. 357, Mare Street, Hackney, in the County
of Middlesex, Warehouseman, do hereby declare the nature of this invention to be
as follows:-
This invention relates to a new or improved window fastener and has for its
object to obtain a simple and inexpensive device which can be arranged either to
secure the window in its closed position, or to prevent its being opened beyond a
given distance.
For this purpose, I form a fastening stop which may be somewhat of the shape
of a triangle, and I mount this stop upon, with capability of turning around, a
vertical pin or axis, carried by an angular fitting, which is shaped to fit the stiles of
the sash.
In attaching the device to a window, the angular fitting is fixed to one of the
stiles of the upper sash, by means of screws, in position either to fasten the window
in its closed position or to prevent its being opened beyond a given distance.
In order to lock or fasten the sash, the stop is turned upon its axis so as to
overhang the top or meeting rail of the lower sash.
When it is desired to open the window, the stop is turned upon its axis so as to
be out of alignment with the meeting rail of the lower sash when the sashes will be
free to be moved.
Dated this 2nd day of October 1890.

COMPLETE SPECIFICATION.
A New or Improved Window Fastener.
I, ALBERT ERNEST ROSE, of No. 357, Mare Street, Hackney, in the County
of Middlesex, Warehouseman, 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 said invention relates to a new or improved window fastener, and has for its
object to obtain a simple and inexpensive device which can be arranged either to
secure the window in its closed position, or to prevent its being opened beyond a
given distance.
For this purpose, I form a fastening stop which may be somewhat of the shape
of a triangle, and I mount this stop upon, with capability of turning around, a
vertical pin or axis carried by an angular fitting, which is shaped to fit the stiles of
the sash.
In attaching the device to a window, the angular fitting is fixed to one of the
stiles of the upper sash, by means of screws, in position, either to fasten the window
in its closed position, or to prevent its being opened beyond a given distance.
In order to lock or fasten the sash, the stop is turned upon its axis so as to
overhang the top or meeting rail of the lower sash.
I will now proceed to refer to the accompanying drawings from which the nature
of my said invention will be more clearly understood. The same letters of reference
indicate like parts in the several figures.
Figure 1, is a perspective view of a fastener constructed in accordance with this

page_text: invention, in which a is the fastening stop, is the vertical pin or axis and c is the
angular fitting.
Figure 2, is a front elevation of portions of the upper and lower sashes d, and e,
of a window showing the fastener attached in such a position to the stile d' of the
upper sash d, that, when it is turned so as to overhang the meeting rail e², of the
lower sash, it will allow the window to be opened to a limited extent. The position
of the fastener, when fixed for retaining the window in a closed position, is indicated
by dotted lines.
Figure 3, is a top view of Figure 2, the fastening stop a, is shown turned so as to
overhang the meeting rail e, of the lower sash e, so as to prevent the opening of
the window or to limit the extent to which the same can be opened. The reverse
position of the said stop is shown in dotted lines; 2 is the meeting rail of the
upper sash d, and e', is the stile of the lower sash e.
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 :-
The new or improved window fastener consisting of a hinged or pivotted stop,
such as a, provided with means for attachment to the stile of the upper sash of the
window, substantially as and for the purposes hereinbefore described and illustrated
in the accompanying drawings.
Dated this 2nd day of July 1891.
