page_text: I SAMUEL BOTT of 4 Bloomsbury Street Birmingham, in the county of Warwick
Manufacturer do hereby declare the nature of this invention to be as follows:
--
This invention relates to fastenings for cupboard doors and such other fastenings
used for similar purposes, and has for its object their construction in such a
manner that the tongue, or catch, having an internally screwed hole to suit screw
thread upon the angles of the spindle, shall be prevented from unscrewing and thus
becoming loose by a second piece or locking key, fitting upon the angular shape
of the said spindle; and such locking key being connected to the tongue in such a
manner that it cannot be lost therefrom either when in, or not in use.
I may carry out this my said invention in several modifications of form, for
instance: I make the spindle of square or any other angular shaped metal,
generally the former, and form upon such angles a screw thread.
Next, I provide the tongue, having a screwed hole to suit the spindle. At the
end or along its sides, the metal of this tongue may be formed of an hinged shape,
and a corresponding binge shaped piece attached thereto which I will call the
locking key. In this locking key, a slot or opening would be cut, to suit the angles
of the spindle, so that when it was turned over (on its hinge) on to the spindle, it
would lie against the tongue, the said hole or opening engaging with the angles of
the spindle so that it (the key) cannot rotate, and by reason of it being attached
to the tongue, also prevents that from rotation upon the screw.
If desired this hinge locking key may be secured by forming a catch upon the
tongue so that when it is turned over against the said tongue it may engage there-
with. This hinge action may be either in a vertical or, in an horizontal plane.
Instead of this hinge action being formed in the ordinary forms of an hinge, I may
form the key in such a manner, that the hinge part may consist of a spring, say for
instance I take a piece of metal and secure one end to the tongue, at a suitable
distance from the spindle, (and, if wire, form one or two spiral coils where thus
secured) and then carry it forward to the spindle, there forming it in such a manner
as to engage with the angles of the said spindle in order to lock it. In this or
similarly constructed cases, the locking key would be held to the spindle by the
spring hinge action.
Instead of this locking key being connected to the tongue in an hinged fashion,
it may be formed to slide upon the surface of the tongue, the slot or opening in it,
engaging as before with the spindle, and in a similar manner, suitable slides being
formed either upon the tongue, or, upon the locking key, for either of them respec-
tively to slide in, and so formed that they cannot become separated.

page_text: I, SAMUEL BOTT of 4 Bloomsbury Street Birmingham, in the county of Warwick
Manufacturer do hereby declare the nature of this my invention for IMPROVEMENTS
IN CUPBOARD TURNS, AND OTHER SIMILAR FASTENINGS 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 fastenings for cupboard doors, and such other fastenings
used for similar purposes, and has for its object their construction in such a manner
that the tongue (in the case of cupboard turns) or its equivalent, a catch, (in other
cases) having an internally screwed hole to suit screw thread upon the angles of
the spindle shall be prevented from unscrewing and thus coming loose, by a second
piece or locking key, fitting upon the angular shape of the said spindle; and such
locking key being connected to the tongue in such a manner that it cannot be lost
therefrom either when in, or not in use.
I may carry out this my said invention in several modifications of form, as I will
proceed to describe:-I make the spindle of square or any other angular shaped
metal, generally the former, and form upon such angles a screw thread. Next
I provide the tongue (or its equivalent) having a screwed hole to suit the spindle.
At the end, or along, its, sides, the metal of this tongue may be formed into a hinge
shape, and a corresponding hinge. shaped piece attached thereto which I will call
the locking key.
In this locking. key, a slot or opening would be cut, to suit the angles of the
spindle, so that when it, was turned over, or passed on to the spindle, it would lie
against the tongue or catch, the said hole or opening engaging with the angles of
the spindle, so that it, (the locking key) cannot rotate, and by reason of it being
attached to the tongue, also prevents that from rotation upon the screw.
If desired this hinge locking key may be secured by forming a catch upon the
tongue so that when it is turned over against the said tongue it may engage there
with. This hinge action may be either in a vertical, or, in an horizontal plane.
Instead of this hinge action being formed in the ordinary form of an hinge, I may
form the key in such a manner, that the, hinge part may consist of a spring, as for
instance, I may take a piece of metal and secure one end to the tongue at a suitable
distance from the spindle, (and if wire, form one or two spiral coils where thus
secured) and then carry it forward to the spindle, there forming it in such a manner
as to engage with the angles of the said spindle in order to lock it. In this or
similarly constructed cases the locking, key would be held to, the spindle by the
spring hinge action, and be forcibly held therefrom during adjustment. Instead of this
locking key being connected to the tongue in an hinged fashion, it may be formed
to slide upon. the surface of the tongue, its slet or opening engaging as before with
the spindle and in a similar manner, suitable slides being formed either upon the
tongue, or upon the locking key, for either of them respectively to slide in, and so
formed that they cannot. become separated..

page_text: I will now proceed to describe this my invention more particularly by the
assistance of the accompanying sheet of drawings whereon are figures and letters of
reference, like letters referring throughout, to the same parts.
Fig. 1 shews this my invention as applied to a cupboard turn or fastening. Fig. 2.
is a front elevation of the tongue and locking key. Fig. 3 is a sectional elevation
of Fig. 1. a, is the spindle which is provided with a screw thread upon its corners
or angles.: b, is the tongue through which a hole c is pierced to receive an internal
screw thread. I may make any of the parts either of cast or wrought metal; but
when making the tongue of wrought metal, I may pierce the hole wherein to form
the screw thread somewhat smaller than the actual size required, and then push
through a tool of the required size, (or, these two operations may be accomplished
by the same tool), thus increasing the depth of the hole to that of the thickness of
the metal out of which the tongue is made; by these means giving a corresponding
greater depth of screw thread in the said hole, than if merely tapped through the
real thickness of the metal of the tongue.
At d, I form an hinge part to receive the corresponding hinge part formed at e
upon the locking key f. At g, I form an angular shaped slot of such a shape and
size to fit the spindle a. It will now be seen that when the tongue is being
adjusted along the spindle the locking key is turned over away from the spindle,
thereby allowing the said tongue freedom to be screwed along into position, but
when so adjusted, the locking key is then turned over on to the spindle, the flat
sides of the slot in the former engaging with those of the latter, preventing further
rotation, that is, screwing or unscrewing.
Fig. 4 shews this my invention applied to the securing of a knob, with the pro-
jecting part of the tongue removed; Fig. 5 being a front elevation of the locking
key f, and catch h. Fig. 6, shews the locking key f and the catch h open or
extended. In this case it will be seen, as before intimated, that the long part of
the arm or tongue b is removed, that being unnecessary when this my invention is
used merely to secure the knob or handle i in position.
Figs. 7, 8, & 9 shew one modification of detail how the hinge part may be
formed; Fig. 9 shewing the shape of the tongue part when cut from sheet or strip
metal, before the ears are turned up to form the said hinge part.
Figs. 10 & 11 shew one method, how provision may be made where necessary to.
prevent any liability of the locking key f becoming disengaged (when in use) from
the spindle a. At l, a portion of the metal of the locking key is made to project
therefrom, so that when in action (as shewn) it shall bind upon the surface of the .
tongue or catch, thus requiring considerable force to disengage it therefrom..
Instead of securing the locking key thus, I may in some instances use a catch or
spring similarly as shewn at m in Figs. 12 & 13.
Figs. 14, 15, & 16 also illustrate a further method of securing the locking key in
its working position. The metal of the tongue at either one or both sides may be
turned up at p, so that when the locking key is turned over on to the spindle,.it
shall pass down inside the piece p, which may be made a little springy, so that
when the locking key is passed down it shall pass a little underneath the said
piece p, just sufficient to hold it there firmly.
Again. Instead of forming and attaching the said locking key in the manner
already described, I may if desired make it of a spring wise forin similarly as
shewn in Figs. 17 & 18, such spring being made of sheet metal or wire, and suitably
attached to the tongue by rivetting or otherwise.
In this or similarly constructed cases the locking key would be held to the
spindle by the spring hinge action, and be forcibly withheld therefrom during
adjustment.
Fig. 19 shews how the arrangement may be made having an horizontal hinge
action.
A further modification of attaching the locking key is shewn in Figs. 20, 21,
& 99 In this case the looking key fia made to slide unon the tongue h the metal

page_text: of the tongue.at.n & o, or at any other suitable position being raised so as to
prevent the removal of the locking key therefrom.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed I declare that what
I claim is:
The locking or securing of cupboard turn tongues to their spindles; and the
locking or securing of knob or handle spindles to doors, drawer fronts, or other
places, by means of a locking key, in the manner hereinsetforth and shewn upon
the drawings.
