Improvements in Cupboard-turns or Fasteners.
I, BENJAMIN HOBBS, of 30 Hart Street, Henley-on-Thames, Builder, etc., 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 relates to improvements in cupboard-turns or fasteners and has
for its object to prevent the tongue from working loose and becoming detached
from its spindle or not acting when the handle or knob is turned.
In such fasteners as hitherto constructed it often happens that the handle may
be turned without operating the tongue so as to lock or unlock the door thus
causing the tongue to be loosened so that it becomes detached from the spindle and
the set screw is lost.
Now according to my invention 1 obviate these imperfections for which purpose
I form the tongue with a circular boss provided with a screw-threaded hole through
its centre and I form a screw-thread upon the outer end of the spindle, carrying
the handle or knob. The tongue can thus be screwed on to the spindle in order to
attach it, by which means also the position of the tongue may be adjusted according
to the thickness of the door. In order to cause the tongue to turn with the spindle
and prevent its becoming unscrewed the boss is provided with a set screw which is
screwed tightly against a groove formed on one side of the spindle four of such
grooves being preferably cut along opposite sides of the screw thread, or a
wedge may be used instead of the screw which is forced into a slot in the
boss and bears against one of four flat sides cut through the screw-threads of
the spindle.
Referring to the accompanying sheet of drawings
Fig. 1 is a plan, partly in section, of my improved fastener attached to a cupboard
door, and
Figs. 2 and 3 are cross sections of different portions of the spindle.
Figs. 4 and 5 are views showing the tongue attached by means of a wedge
or key.
is the tongue and a' its circular boss formed with a screw-threaded hole
through its centre. 6 is the knob or handle whose spindle is formed with a screw-
threaded portion 1, 62 are four grooves or recesses, shown in Fig. 3 cut in the
threads for receiving the end of the set screw a screwed into the boss a¹
for preventing the tongue from turning on the said screwed portion of the
spindle.
The spindle is carried and works in a sleeve c formed in one with the rose or
flange c, which latter is provided with spikes 3 let into the woodwork of the
door d to prevent the sleeve from turning. This sleeve is forined with a slot e
with which engages with head of a screw el screwed to the spindle, for the purpose
of preventing the handle and tongue being turned more than one quarter of a
revolution as shown in Fig. 2 ƒ is a bearing plate or washer provided with the
spikes for preventing its being turned, and g is a plate screwed to the
door and against which the tongue catches so as to prevent wearing of
the woodwork.
The tongue is screwed to the end of the spindle until in proper position for
working and the screw el is screwed into its bars for fixing it to the spindle as

page_text: aforesaid. Instead of using the set screw e¹ I may use a wedge or key h Figs. 4
and 5 for screwing the tongue in position the boss at being formed with a square
slot for receiving the same and the screwed end of the spindle being provided with
four plane surfaces & against which the wedge or key bears.
Having now particularly described and ascertained the nature of my said inven-
tion, I declare that what I claim is,--
+
(1.) In cupboard-turns or fasteners forming the tongue with a boss provided with
a screw-threaded hole engaging. with a screw-threaded portion of the spindle, the
parts being locked together by means of a set screw or a wedge substantially as
described and for the purposes specified.
(2.) In cupboard turns or fasteners the combination of the tongue a and screwed
boss a set screw a knob or handle b, screwed spindle o¹ formed with grooves b³,
sleeve c, rose c¹ spikes ², slot e, screw e¹, plate f, spikes and plate g, substantially
as described and for the purposes specified.
(3.) The improved cupboard-turn or fastener substantially as described with
reference to Figs. 1, 2, and 3, and to Figs. 4 and 5 of the accompanying
drawings.
