IMPROVEMENTS IN CUPBOARD TURN OR FASTENER
Year: 1884

page_text: J, EDWIN HENRY BAXTER, Manufacturer, of 58 Auckland Road Sparkbrook,
Birmingham, Warwickshire, do hereby declare the nature of said Invention for
"IMPROVEMENTS IN CUPBOARD TURN OR FASTENER" to be as follows:-
Heretoforo in Cupboard "Turns" or Fasteners, it has been usual to employ a
square spindle threaded at the edges to receive a screwed tongue provided with a
small set screw to lock it on the spindle at the required distance from the end.
Owing to the frequent turning of the spindle for opening the door to which it is
applied, the small set screw in the tongue is liable to work loose and allow the
tongue to unscrew from the spindle and become disconnected and inoperative as a
fastener.
Now my invention has for object to prevent the tongue from turning or becoming
loose on the spindle after being set or adjusted and this I effect by means illustrated
in the accompanying sheet of drawings where
Fig 1 is a longitudinal sectional clevation Fig 2 an end view-Figs 3 side and
end views of coupling and Figs. 4 shew the tongue in two views at right angles to
one another.
The knob A is provided with a square spindle B and tongue C as usual, but the
tongue C has a boss with a square hole through it to receive the spindle. The
outside of said boss is formed with the same number of threads per inch as the
square spindle. A screw coupling D is used with threads to correspond with those
on the tongue and spindle so as to secure and lock the tongue in the required
position on the spindle. By this arrangement the tongue will not be disconnected
from the spindle by any movement of the knob A used for opening or closing the
door to which it is applied.

page_text: I, EDWIN HENRY BAXTER, Manufacturer of 58 Auckland Road, Sparkbrook,
Birmingham, Warwickshire, do hereby declare the nature of my invention for
"IMPROVEMENTS IN CUPBOARD TURN OR FASTENER" and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement:—
Heretofore in cupboard turns or fasteners it has been usual to employ a square
spindle threaded at the edges to receive a screwed tongue provided with a small
set screw to lock it on the spindle at the required distance from the end. Owing
to the frequent turning of the spindle for opening the door to which it is applied
the small set screw in the tongue is liable to work loose and allow the tongue to
unscrew from the spindle and become disconnected and inoperative as a fastener.
Now my invention has for object to prevent the tongue from turning or
becoming loose on the spindle after being set or adjusted and this I effect by
means illustrated in the accompanying sheet of drawings where Fig 1 is n
longitudinal elevation, Fig. 2 a similar view partly in section, Fig 3 an end
view, Figs. 4 longitudinal section and end view of coupling, and Figs 5 shew the
tongue in two views at right angles to one another. The knob A is provided with
a square spindle B and tongue C as usual, but the tongue C has a boss C¹ with a
square hole through it to receive the spindle. The outside of the boss is formed
-with-the same number of threads per inch as the square spindle. A screw
coupling D is used with threads to correspond with those on the tongue and
spindle so as to secure and lock the tongue in the required position on the spindle.
By-this-arrangement the tongue will not be disconnected from the spindle by
any movement of the knob A-used-for-opening or closing the door-to which it is
applied.
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. In a fastener of the kind hereinabove referred to the use of a coupling having
holes of two diameters one formed with threads to correspond with threads on the
spindle and the other formed with threads to correspond with threads on a boss of
the tongue, substantially as described and illustrated for the purposes specified.
2. The improved cupboard turn or fastener shewn in and described with reference
to the accompanying sheet of drawings.
Dated this 10th day of October 1884.
