Improvements in the Construction and Securing of Bedstead and
other Knobs.
I, JOHN CAULTON, Potter, Garden Terrace, Alfred Street Ripley, Derby, do
hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a ready and effective means of
securing bedstead and other knobs, so that they cannot be easily unscrewed and
knocked off accidentally.
I will first describe my invention as applied to a bedstead knob; these are now
generally simply screwed on to a threaded spindle or the like at each corner of
the bed and so are constantly getting unscrewed accidentaliy and tumble off.
In carrying out my invention I provide a hollow knob in two parts which are
screwed together the inner or larger part is passed over the threaded spindle on
the bedstead and a nut is screwed on to the spindle from the inside of the larger
part of the knob until the latter is tightly screwed home, the smaller or outer
part of the knob is now screwed on or into the larger part, the method by which
the said knob is secured being thus not visible from the outside. The nuts may
be of any ordinary or special shape and provided with suitable spanners or keys.
In the case of a knob fixed to an outer door a spindle would be provided to
pass through the door but terminating on the outer side in a plain projecting
rivet end, the nut being fixed from the inside of the door so that it cannot be
taken off from the outside.
Any suitable washers, either plain or of a non-revolving nature such as a
D shape, may be used according to the different positions or purposes in or for
which the knobs may be required. My invention may be applied to ordinary door
furniture by providing a fixed back bearing for the face of the inner or larger
part of the knob to butt up to when being fixed.
It will be evident that the two parts of my improved knob may be made of any
suitable substance such as earthenware, china, metal or the like.

Improvements in the Construction and Securing of Bedstead and
other Knobs.
I; JOHN CAULTON of Garden Terrace, Alfred Street, Ripley in the County of
Derby, Potter, 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 :-
The object of my invention is to provide a ready and effective means of securing

page_text: off accidentally.
In describing my invention reference will be had to the figures upon the
accompanying sheet of drawings.
Figure 1 is a vertical section through a bedstead knob fixed according to my
invention.
Figure 2 is a plan shewing the nut and washer used in fixing the knob illustrated
on Figure 1.
Figure 3 is a drawing of the end of the key or spanner used for operating the
nut illustrated on Figures 1 and 2, as will be hereinafter explained.
Figure 4 is a section through a door knob fixed according to my invention.
I will first describe my invention as applied to a bedstead knob; these are now
generally simply screwed on to a threaded spindle or the like at each corner of
the bed and so are constantly getting unscrewed accidentally, and tumble off.
In carrying out my invention I provide a hollow knob in two parts A and B which
are screwed together, the inner or larger part A is passed over the threaded spindle C
on the bedstead and a nut D is screwed on to the spindle from the inside of the larger
part of the knob until the latter is tightly screwed home, the smaller or outer part of
the knob B is now screwed on or into the larger part; the method by which the said
knob is secured being thus not visible from the outside. The nuts and washers may
be of any ordinary or special shape and provided with suitable spanners or keys. For
instance upon Figure 1 and 2 a non-revolving D-shaped washer E is shewn whose
flat side engages the flat side of the threaded spindle C the nut D being also of a
special form carrying lugs or projections D1 D2 at the sides which fit into the slots F
in the end of the spanner or key illustrated upon Figure 3.
In the case of a knob fixed to an outer door a spindle would be provided to pass
through the door but terminating on the outer side in a plain projecting rivet end,
upon which the knob would first be fixed the nut being fixed from the inside of the
door and thus firmly securing the whole together so that the knob cannot be taken off
from the outside.
My invention may be applied to ordinary door furniture as illustrated upon Figure 4
by providing a fixed back hearing such as the nut G for the face of the inner or larger
part H of the knob to butt up to when being fixed, the spindle K projecting into the
said inner part H and the whole being secured by means of the nut L after which the
outer part I of the knob is screwed on as already described. The two nuts G and L
will be found in practical use to firmly lock the whole together.
It will be evident that the two parts of my improved knob may be made of any
suitable substance such as earthenware, china, metal or the like and that the said
ordinary or special nuts or washers may be of any required standard sizes and
interchangeable.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in the construction and securing of bedstead, door and other
knobs consisting of forming each of the said knobs in two parts, one screwing
into the other, the inner part of the said knob being secured in position on the
spindle by means of nuts and washers or ordinary or special form operated by
means of ordinary or special keys or spanners, and the outer part of the knob
being then screwed on to or into the inner part substantially as described and
illustrated.
