Improvements in Locks..
We, JOHN PATON and HAMILTON CURRIE, both of 285, New City Road, in the
County of the City of Glasgow, North Britain, Cabinet Makers, 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 has special reference to what are known as pedestal, cabinet,
wardrobe, chest of drawers, and analogous locks.
Hitherto it has been the practice to recess the wood work wherein it is intended
to place the lock and insert a bolt plate in the opposite part of the framework. The
object of the present invention is to obviate this troublesome and protracted form of
fitting, and produce a lock and stop device which can be fitted in position expe-
ditiously and without an incision being made in the cabinet work.
In order that our invention may be properly understood and readily carried into
effect we have hereunto appended one sheet of drawings of which
Figure 1 is a transverse section of, a drawer partially open and fore edge, to which
our improvements are employed.
Figure 2 is a similar view, showing the drawer closed.
Figure 3 is a blank cut from a sheet of brass, which is to constitute the case or
framework of the lock.
Figure 4 is a similar view of the case or framework illustrating a more advanced
stage of the operation
Figure 5 is an end view of the lock case or framework in a state of completion
and
Figure 6 is a front view and side elevation respectively of the stop device all
hereafter more fully referred to.
The lock A shown in Figures 1 and 2 is of the ordinary slip bolt type (the internal
arrangement of which forms no part of our present invention) is screwed to the inner
batten or stile B of the drawer by screws or screw nails. It will be seen that the
top of the lock is not flush with the edge of the drawer; from Figure 2 it will be
better understood why this is so.
The drawer when shut comes against the pro-
jecting face of the stop C which prevents it from being further pushed into its
receptacle. Stops formed of wood have usually been employed, which are placed
at the rear end of the drawer; by our improved stop device these are entirely
superseded. The drawer when in this position (as seen in Figure 2) is free to be
locked, which operation as there shown having been performed, the stop C coming
between the out shot bolt a and the stile of the drawer B, the case or frame of the
lock is made entirely of one piece of metal D preferably of brass as is represented
by the blank shown in Figure 3. The blank is then shaped by a tool or mandril
until it assumes the form represented in Figure 4. Screw holes, bolt and key holes
are shown as having been punched, and the flap or plate d remains only to be bent
over to form the sole plate of the lock casing as seen in Figure 5.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is:
The improvements in locks, substantially as and for the purposes hereinbefore
described and illustrated on the accompanying sheet of drawings.
Dated this 24th day of February 1898.
