PROVISIONAL SPECIFICATION.
An Improved Cupboard-turn or Door-fastener.
I, WILLIAM DOUSLIN of Blenheim, Marlborough in the Colony of New Zealand,
Architect, do hereby declare the nature of this invention to be as follows:-
In place of the ordinary latch having a square socket hole and held upon the
spindle of cupboard turn by means of a nut, which frequently works loose and
becomes unserviceable, I employ a latch mounted upon a spindle of nearly square
section upon the corners of which spindle a scrow thread is formed and this spindle is
fixed into a kob of brass, glass, or other suitable material.
Through the spindle is formed a longitudinal slot, which receives a set-screw
secured to and passing quite through both sides of the boss of the latch, when
screwed up to its required position, according to the thickness of the door. This
set-screw fixed as described prevents the latch from turning or shaking loose upon
the spindle.
Dated this Twenty-sixth day of June 1889.

COMPLETE SPECIFICATION.
An Improved Cupboard-turn or Door-fastener.
I WILLIAM DOUSLIN of Blenheim, Marlborough in the Colony of New Zealand,
Architect, 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 invention relates to an improved form of spindle for cupboard turns or door
fasteners, and also to an improved device for securing the tongue or latch to the
spindle thereof.
In order to enable my invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings, in which,
Figure 1 represents a sectional plan of a portion of a cupboard door with my
improved fastener fitted thereto.
Figure 2 represents an elevation of the tongue or latch, and Figure 3 the knob
with slotted spindle.
Similar letters refer to similar parts in all the figures.
The knob is represented at A into which is firmly fixed the spindle B, in which is
formed the long slot E.
The spindle is passed through a hole made to receive it in the door H, and upon
the projecting portion of the spindle B is screwed the boss D of the tongue C.
When this boss has been adjusted so as to touch the door but to allow the knob to
turn easily, the screw F is then passed through both sides of the boss D and at the
same time through the slot E of the spindle B, whereby the boss and tongue are
prevented from slackening or unscrewing.
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 I
claim is,
In cupboard turns or door fasteners, a slotted spindle through the slot of which
passes a screw fixed into both sides of the boss of the tongue or latch, the boss

page_text: being screwed upon the spindle and prevented by means of the screw from slackening
or unscrewing, these various parts being formed and operating substantially in the
manner described and represented in.the accompanying drawings.
