PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Sashes and other Articles.
I, JOHN TIMOTHY BROWN of 47 Mount Pleasant, Reading, in the County of
Berks., Whitesmith, do hereby declare the nature of this invention to be as
follows:-
This invention consists in adding to the ordinary sash or casement fastener a
small fixed lock and key, so that it can be securely fastened whether used in a
horizontal or vertical position.
The lock has a bevelled spring bolt or catch, and the moving arm of the fastener
has a suitable hole to receive the bolt of the lock. The arm of the fastener is also
bevelled so as to lift the catch and pass readily under it when the fastener is
closed. The bolt therefore locks itself automatically, and holds the fastener
securely until the key is turned, when the spring bolt being raised the fastener is
released.
My self locking fastener is applicable as an outside lock for a variety of purposes
such as glass doors, cupboard doors, drawers, and boxes, and avoids the necessity
of cutting away the wood, and thereby weakening the structure.

COMPLETE SPECIFICATION.
Improvements in Fastenings for Sashes and other Articles.
I, JOHN TIMOTHY BROWN of 47 Mount Pleasant, Reading, in the County of
Berks., Whitesmith, 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 is designed to supply a safe automatically locking fastener for
window sashes in country houses and other exposed situations. It is also applicable
to casements and sashes which open horizontally on hinges, as well as to those
hung on cords and opening vertically, and is suitable as an outside fastener for
drawers, boxes, glass-cases, cupboards and showcases, and especially those which
have narrow stiles, which it is undesirable to weaken by inserting mortise or inside
locks in the usual way.
I will now proceed to describe the invention with reference to the accompanying
drawings in which Fig. shews a front elevation and Fig. 2 a plan of one of my

that the invention consists in adding to the ordinary sash or casement fastener a
small fixed lock and key 1, so that it can be securely fastened whether used in a
horizontal or vertical position.
Fig. 3 shows a plan of another form of my fastener specially adapted for vertical

which I add to secure the arm a, and it is furnished with a bevelled spring bolt or
catch m under the horn c. In order to engage automatically with the spring bolt m,
the arm a has a bevelled projection e, in which is the opening. When the arm a
is closed, or placed in the position shewn in Fig. 1, the end of the projection e lifts

page_text: the bolt m until the end of the spring bolt is resting in the opening as shewn in
Fig. 4.
The arm a cannot then be drawn back until the bolt mis raised out off by
means of the key of the lock. It will thus be seen that the arm a cannot be opened
by inserting a blade between d and d, nor by cutting a hole in the glass, as is the
case with the ordinary fastener. The lock is firmly attached to the plate d, or is
made solid therewith.
In order to prevent my fastener from being taken off the sash by withdrawing
the screws, some of the screw holes are placed under the locking arm, so that the
arm must be unlocked before they can be removed.
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 1
claim is :
The method of combining a lock with an ordinary sash or casement fastener, as
herein described and set forth.
