Specification Accepted, 4th Oct., 1887.
I, EDWARD VERNON BAILEY of Great Hampton Row Birmingham in the County of
Warwick, Manufacturer, 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 for its object principally, to simplify the construction, and to
render more efficient and convenient when in use, cupboard turns, employed in the
fastening of doors, and windows.
Instead of making the turn in a single piece, I make it in two parts, jointed at their
outer ends, and with the inner ends, square gapped, and screwed respectively; that is,
the turn itself, is composed of two parts or arus, jointed at their inner ends, so as to
turn outwardly in the same plane, and with the inner end of the one part, provided
with a screwed hole, and the inner end of the other part, provided with a side, gapped
and square hole.
On affixing the turn upon a spindle, the screwed hole as aforesaid, takes upon the
screw thereof, and after adjustment, the other part is turned with its gapped end,
engaging upon the top and bottom sides of the spindle, which on a screw nut being
brought up to position, firmly locks and fixes the turn.
Or the segmental turn may be made without a joint, and locked by a turned end of
the one, engaging with a gap in the other.
I will now proceed to describe with reference to the accompanying drawing, the
manner in which the same is to be performed.
Figure 1 represents in front elevation, a cupboard turn, made according to my
invention. Figure 2 shows the same partly in vertical section. Figure 3 is an end
view upon the dotted lines A B, figure 1, thus exhibiting the outer segmental part of
the turn, embracing the square of the spindle. Figuro shows a front elevation of
the turn upon the spindle, on adjustment, and before the gapped part, of the other part
has been made to embrace the spindle, for locking. Figure 5 exhibits an end elevation
of the turn upon the spindle, before being affixed, as aforesaid.
The same letters of reference indicate corresponding parts in figures 1 to 5 of the
drawing.
a is the nob, b is a screwed spindle, and c, d is a segmental turn, jointed at e, at their
outer ends, so as to be capable of turning outwardly, in the same plane, and upon the
joint e as a centre. The part c, has a screwed hole c², near its inner end, while the
part d, has a side and square gapped hole d², near its inner end; and when the two

page_text: parts of the turn c, d, are in position, the gap of the one comes in front of, and opposite
the screwed hole in the other.
To affix the turn upon its spindle, in an adjusted position, screw or rotate the part c
upon its spindle, and when adjusted, close the segmental parts, by making the part d
become coincident with the part e, and with the square gapped part d² thereof,
embracing or partially surrounding the said spindle, which theroby locks and secures
the turn thereof, in an adjusted position.
The displacement of the turn, is prevented by the screwing up of the nut f, so as to
make its inner face take a firm abutment over the gap of the part d.
If necessary, the part surrounding the gap, may be slightly sunken, wherein a
collar on the front of the nut takes its bearing.
Figure 6 represents a modification, in which displacement of the turn after
adjustment is prevented, by a small screw passing through, or connected with the
outer and gapped part. b is the spindle, c is the inner part with screwed hole c².
d is the outer part, jointed to c at e; and e², is a gapped part, while f is a small
screw which passes through a pressed out part d³. The point of which said screw,
engages within a groove in the spindle.
Figure 7 represents another form of any invention, in which connection is made, by
a turned end on the one part, engaging with a gapped end, on the other part.
Figure 8 represents the parts of the turn separately.
b is a screwed spindle, c is a segmental half of the turn, with a screwed hole c², at
its upper end, and a gapped part 3 at its lower end. d is the other segmental half of
the turn, with rectangular hole d², at its upper end, and returned end or foot d³, at its
other end; and which said foot part d³, fits into a corresponding gapped part c³, of the
other part.
In adjusting the turn, screw part e into position upon its spindle, then pass or thread
the part d, upon the back of it, and with the foot d³ resting within the gap c³, which
locks the two parts together, and prevents their rotation or displacement, and which
parts are kept in their adjusted position, by a screw nut, screwing upon the end of
the spindle, and taking its bearing against the part d.
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.
First. Making the turn, or the securing arm of a cupboard turn, in two parts, or
in two segments c, d, connected together and jointed at e, at their lower ends, while
their respective upper ends, are pierced with a screw hole c², and a rectangular gapped
hole and which said turn is or are kept in position, by a screw nut f; (or by a
small screw as in modification figure 6). The turn is constructed, arranged, adjusted
and locked, substantially as described and set forth in figures 1, 2, 3, 4, 5 and 6 of the
drawing.
Secondly. Making the turn, or the securing arm of cupboard turns, in two parts, or
in two segments, whose upper ends are respectively provided with a screwed hole c²,
and a rectangular pierced hole d², while the parts are locked together by a foot or
lug d on the one, taking into a like gapped part e in the lower part of the other;
and which parts are kept in their locked and adjusted position by a nut f, as described
and set forth in figures 7 and 8.
