Improved Automatic Fastener for Cupboard Doors and the like.
I, JOHN BURN, of 7, Cedar Road, Carr Croft, Armley, Leeds, in the County of
York, Mechanic, do hereby declare the nature of this invention to be as follows:
My fastener consists of the ordinary knob and spindle, the end of the spindle
terminating in a catch or hook. The spindle is pivotted to a plate or bracket which
is secured to the outside of the cupboard door. On the underside of the shelf is
fixed a projection or catch bevelled on its underside towards the door. The hook
or catch end of the spindle is bevelled on its top end side. The spindle passes
through a recess in the door tapered or widening at its underside.
The knob end of the spindle being the heaviest, holds the spindle end up in
position to engage with the projection on the underside of the shelf, so that on
closing the door it automatically slides over the incline of the projection and locks
on the face of the same.
To disengage it, the knob only requires lifting or pushing upwards. A plate
may also be fixed inside the cupboard door to regulate the position of the projection
and amount of drop or movement of the spindle.

Improved Automatic Fastener for Cupboard Doors and the like.
I, JOHN BURN, of 7, Cedar Road, Carr Croft, Armley, Leeds, in the County of
York, Mechanic, 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:
The object of my invention is to construct a simple and efficient automatic
fastener for cupboard or the like doors.
DESCRIPTION OF DRAWINGS.
Fig. 2 is a plan, in part section, of my improvements applied to the ordinary
folding cupboard doors.
Fig. 1 is a sectional elevation of Fig. 2, the section being taken through the outer
door at the fastener.

page_text: Fig. 3 is a plan of my improvements applied to a single door, or to folding doors
where there are no shelves.
My fastener consists of the ordinary knob or handle A with spindle or lever B,
the said spindle or lever terminating in an inclined catch or hook C. The spindle
or lever B is pivotted at D to a plate or bracket E which is screwed or otherwise
secured to the outside of the cupboard door F. A projection or catch G, inclined or
bevelled on its underside towards the door, is fixed preferably on the underside of
the shelf H (see Figs. 1 and 2). The spindle or lever B passes through a tapered
recess J in the door, the recess being wider towards the inside of the door. The
knob end of the spindle being the heavier, the hook end C of the spindle is held up
in position to engage with the projection or catch G on the underside of the shelf,
so that on the door being closed the hook C automatically slides over the incline of
the said projection or catch G, and locks on the face of same. To disengage the
hook the knob only requires lifting or pushing upwards.
The spindle or lever B passes through a slotted plate K fixed inside the door to
regulate the position of the hook or catch C and the amount of drop or movement
of the said spindle or lever in the recess.
In the case of folding doors the inner door L may be secured by any ordinary
fastener M (see Fig. 2).
In the case of a single door (see Fig. 3), or folding doors where there are no
shelves, the projection or catch G may be fixed to the stile N as shown in the
drawing.
The said projection or catch may also be made with a double incline so as to be
reversible.
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. An automatic fastener for cupboard doors and the like, consisting of a pivotted
spindle or lever with a hook or catch end which automatically engages with a
suitable fixed projection within the cupboard and is released therefrom by raising
a knob or handle as described.
2. The combination of the knob or handle A, pivotted spindle or lever B,
hook C, pivot bracket E, inclined projection or catch G, and adjusting plate K,
as shown and described.
