PROVISIONAL SPECIFICATION.
Improved Means for Fixing or Screwing the Knobs of Iron and
other Bedsteads and the like.
We, JAMES SETON PRENTICE, Engineer, of 192 Hope Street, WILLIAM
RENISON, Manufacturer of 12 Belmont Crescent, and JOHN RENISON, Ship
Broker of 157 West George Street, all of Glasgow in the County of Lanark,
North Britain, do hereby declare the nature of this invention to be
follows:-
as
This invention relates to improved means for fixing or screwing the knobs of
iron, brass and other bedsteads; and the like, such as the knobs of ornamental
railings for example. In the carrying out of our invention as applicable to the
fixing of the knobs of iron bedsteads for example, we provide a screwed hole
through the top of the brass or other knob, and we provide a screwed cap to fit
into and through the said top of the knob. The said cap has an elongated stem
which is internally screwed. The spindle to receive the knob is formed square, but
with its upper extremity screwed. The arrangement is such that when the knob is
fitted on to the spindle (the neck of the knob having a square aperture to
correspond with the spindle) the elongated cap is passed through the top of the
knob and by giving a few turns to it, its internal screw is engaged with the screw
at the top of the spindle which projects through the neck of the knob to a certain
distance within the knob; and by continuing to turn the cap the external screw at
the top thereof engages with the internal screw at the top of the knob. By this
ineans the knob is not only forced tight upon the spindle but it is bound or locked
by the said internally and externally screwed parts of the cap respectively. The
cap may be fixed on either by a spanner or by a screw-driver according to the
desired formation of the head of the cap.
As a modification of our said invention or in cases where the knob is of glass
china wood and the like and an internal screw cannot be properly formed in the
head of the knob, we provide the brass or other metal neck of such a knob as an
internal extension piece screwed externally and we alter the cap so that instead of
the external screw we provide the end of the cap with an internal screwed sleeve,
so that when the cap is passed through the head of the knob it first takes on to the
screwed spindle and then on to the external screw of the internal extension piece of
the knob.

Improved Means for Fixing or Screwing the Knobs of Iron and

We, JAMES SETON PRENTICE, Engineer, of 192 Hope Street, WILLIAM
RENISON, Manufacturer of 12 Belmont Crescent, and JOHN RENISON, Ship
Broker of 157 West George Street, all of Glasgow in the County of Lanark,
North Britain, 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 improved means for fixing or screwing the knobs of
iron, brass and other bedsteads to their spindles, and has for its object to prevent

page_text: the knobs wearing loose. The invention is applicable to the fixing of all similar
ornamental knobs and the like.
As shown in section Figure 1 the hollow brass or other metal knob is formed
with a square hole to receive the square spindle A of the bedstead. The top of the
spindle is screwed to receive the internally screwed cap B which cap is locked to
the top of the knob by the screw b; the cap, in this example, being formed square
so as to screw up with a spanner.
When the knob is of china for example, as shown in Figure 2, the bottom of the
knob may be provided with a brass or other metal socket piece C formed with a
square hole to receive the square spindle A and the knob is clamped up tight upon
the spindle by means of the elongated nut D which is screwed on to the spindle at E
and also screwed on to the socket at F. In this example the nut is shown as
operated by a screw-driver.
Figure 3 is another modification of another shape of knob and in which the nut
is flush with the top of the knob.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In bedstead knobs and the like the improved means for securing the knobs to
their spindles substantially as herein before described and shown in the accompanying
drawing.
2. In the fixing of bedstead knobs and the like to their spindles, the locking
arrangement effected by the screwing of the cap both to the spindle and to the
knob, by means of which the spindle and knob become one fixed body substantially
as and for the purpose hereinbefore described and shown in the accompanying
drawings.
