page_text: County of Stafford China Manufacturer, do hereby declare the nature of this invention
to be as follows:-
I will now describe my invention :-
Fig. 1 Represents a plan of the tongue.
Fig. 2 Represents section in clevation through (fh Fig. 1).
Fig. 3 Represents a screw with head, without nut.
Fig. 4 Represents a screw with nut at each end.
Fig. 5 Represents my improved cupboard turn in position attached to the door, the
door being in section.
Instead of the square spindle or shank, which I will in future call spindle,' at
present used in cupboard turns and turnbuckles I make the spindle (J Fig. 5) out of
round, angular or oval drawn iron, steel, brass, or any other metal, wire. I prefer
round wire and have only sketched round, but the said spindle may be turned, forged,
cast or stamped instead of being drawn. I fix this said spindle (J Fig. 5) to the
knob (K Fig. 5) either by the method known in the trade as leading in,' or by
rivetting, pressing, screwing, soldering, or laying in, to the mount (1 M Fig. 5). I
nake the tongue (N. O Fig. 5) in form as shown (Figs. 1 & 2) as this is the most
used; but its form may vary so long as it has 'cam' action; but one of the special
features in my improved tongue is that it has two jaws as shown (a & b Fig. 1 &
Fig. 2) through one of which I make a plain hole, in position (C Fig. 1 & S Fig. 2).
This said hole being of such a size as to allow the screwed part of screw (Fig. 3) to
pass freely through. I also make a hole ( Fig. 1) in line with the said hole (C Fig. 1)
but this hole (C) I tap to fit the screwed part of screw (Fig. 3).
The beforementioned jaws are inade solid with the body of the said tongue but
between the said two jaws I make or leave a gap which is quite open from the out-
side at (f Fig. 1) to ( Fig. 1), the inside of hole (e Fig. 1) & (tu Fig. 2) which said
hole (e) & (tu) I make to correspond with the size and form of the said
spindle (J Fig. 5).
Now to attach my improved cupboard turn to the door I push the said spindle
through a hole in the door as usual. I then pass the said tongue onto the said
spindle in position as shown (NO Fig. 5), after which I push the screw as Fig. 3
through the said hole (C Fig. 1), and then screw it into or through the said
hole ( Fig. 1). At the same time I use sufficient force in turning the said screw as
to enable the said screw to draw the said jaws together; which action causes the
tongue to grip the spindle as shown (Fig. 5). For the purpose of drawing the jaws
together I could use a longer screw with a nut, as those (X Y Fig. 4) at one end and
the head at the other end as Fig. 3. In which case I could dispense with the tapping
of hole ( Fig. 1) or I could, for the same purpose use a screw with a nut at each end
as shown (Fig. 4). The size of the said tongue would vary according to the require-
nents of the door, also the strength would vary for the same reason.

page_text: I can make this said tongue either by casting, stamping, by the aid of the press or
machine.
I can apply this improvement to cupboard turns or turnbuckles made of brass or
any other metal, china, glass, wood, bone or any other material.

RICHARD THOMAS GROCOTT.
I, RICHARD THOMAS GROCOTT of Whitehall Works Longport Stoke-on-Trent in the
County of Stafford, China 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 relates to a cupboard turn or turnbuckle and it has for its object
more particularly an improved tongue which when secured to the spindle of the
turnbuckle will remain firmly in position and not become loose as is the case with
those now in use.
Referring to the drawings accompanying my Provisional Specification―
Figure 1 represents a plan of the tongue;
Figure 2 a sectional elevation through fh Figure 1;
Figure 3 represents a set screw;
Figure 4 a bolt with nut at each end and
Figure 5 my improved cupboard turn in position in the door, the door being in
section.
Instead of the usual square spindle or shank (hereinafter called spindle) at present in
use, I form the spindle J, Figure 5, round, angular or oval in cross section and of any
suitable metal such as iron steel or brass but I prefer such spindle of round cross
section. I fix the said spindle J to the knob K either by the method known in the
trade as leading in" or by rivetting, pressing, screwing, soldering, or in any other
suitable way to the mount L, M, Figure 5, and I form the tongue NO, Figure 5 as
shown in Figures 1 and 2, as this is the most used but it may take other forms as
long as it has "cam" action the special feature of the invention however being that
the tongue has two jaws a b, Figure 1.
One of the jaws is provided with a plain hole c, Figure 1, and 8, Figure 2, which is
of such a size as to allow the screwed part of the set screw shown in Figure 3 to
pass freely through but the hole in the other jaw is screw threaded to receive
the screwed portion of the said set screw. These jaws are solid with the body of the
tongue but a space or gap is left between them for tightening up purposes. The
hole e, Figure 1, corresponds with the size and form of the spindle J.
Now to attach my improved cupboard turn to the door I push the said spindle
through a hole in the door as usual. I then pass the said tongue on to the said spindle in
position as shown (N O Figure 5), after which I push the screw as (Figure 3) through
the said hole (C Figure 1) and then screw it into or through the said hole (d Figure 1).
At the same time I use sufficient force in turning the said screw to enable the said
screw to draw the said jaws together; which action causes the tongue to grip the
spindle as shown (Figure 5). For the purpose of drawing the jaws together, I could
use a longer screw with a nut, as shown ( y Figure 4) at one end and a head at the
other end as Figure 3. In which case I could dispense with the tapping of hole (d
Figure 1) or I could, for the same perpose use a screw with a nut at each end as
shown (Figure 4). The size of the said tongue would vary according to the
requirements of the door, also the strength would vary for the same reason. I can

page_text: make this said tongue cither by casting, stamping, by the aid of the press or
machine.
I can apply this improvement to cupboard turns or turnbuckles made of brass or
any other metal, china, glass, wood, bone or any other material.
In combination with this improved tongue I may also provide stops or projections
to limit the travel thereof.
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. The improvement in cupboard turns or turnbuckles, which consists in forming
the tongues thereof substantially as herein described and shown on the accompanying
drawing whereby such tongues are held more firmly on the spindle and are less liable
to become loose than those hitherto constructed.
2. In a cupboard turn or turnbuckle, the combination with a spindle of round,
angular, or oval cross section, of a tongue having a hole corresponding in size and
form with such spindle and flanges or jaws ab which jaws, when the tongue is in
position on the spindle, are drawn together by means of bolts or set screws thereby
causing the tongue to firmly grip the spindle and to be retained in such position
substantially as hereindescribed and illustrated on the accompanying drawings.
