PROVISIONAL SPECIFICATION.
An Improvement in connecting the Terminal Ornaments of Metallic
Bedsteads and other Articles of Metallic Furniture to the Pillars
of the same, which Improvement is also applicable to other like
purposes.
We, VINCENT EDWIN JAMES, of No. 66 Beach Road, Sparkhill, Yardley, in the
County of Worcester, Manager of Works, and JOHN JONES, of No. 3 Brunswick
Road, Balsall Heath, Birmingham, in the County of Warwick, Foreman of Works,
do hereby declare the nature of this Invention to be as follows:―
We will describe our invention as applied to the connecting of the terminal
ornament of a metallic bedstead to the top of the pillar of the same.
This connection is ordinarily effected by means of a screw at the top of the
pillar taking into a screw nut in the base of the ornament.
It frequently happens that an inperfection in the thread of the screw occasions
some difficulty in making the thread of the screw nut engage properly with the
said screw and the ornament when screwed home may not seat itself closely on the
top of the pillar. In other cases the defective screw thread fails to properly bind
or connect the ornament to the pillar and the ornament is consequently liable to
be accidentally detached.
In attaching the ornament according to our invention we dispense with the
ordinary screw nut in the base of the ornament and substitute therefor an inverted
cup of the kind hereinafter described made of sheet steel or other elastic metal or
alloy. The said cup has a central opening of a size suitable to engage in the groove
of the screw of the bedstead pillar and three or other number of radial slits or
notches are made in the cup which slits or notches pass into the central opening
described. The said slits or notches permit of the central opening in the cup being
slightly expanded and contracted. The said inverted elastic cup is connected to
the base of the ornament by burnishing or otherwise.
In attaching the ornament its base containing the elastic cup is placed on the
end of the screw of the pillar and the said ornament turned exactly as if it con-
tained an ordinary screw nut. By the screwing motion of the ornament the edge
of the central opening in the elastic cup engages with the thread of the screw and
the continued turning of the ornament screws it home. When the base of the
ornament seats itself on the to of the pillar the further turning of the ornament
causes the thread of the screw to draw downwards the central part of the elastic
cup thereby somewhat flattening the said part and contracting the central opening
so as to make it bind tightly in the groove of the screw. The ornament can thus
be made to bind very tightly on the top of the pillar and it is scarcely possible for
the ornament to become detached accidentally.
Terminal ornaments of curtain rods cornice poles and the ornaments of fenders

with respect to the terminal ornament of the pillar of a metallic bedstead.

An Improvement in connecting the Terminal Ornaments of Metallic
Bedsteads and other Articles of Metallic Furniture to the Pillars
of the same, which Improvement is also applicable to other like
purposes.
We, VINCENT EDWIN JAMES, of No. 66 Beach Road, Sparkhill, Yardley, in the
County of Worcester, Manager of Works, and JoHN JONES, of No. 3 Brunswick
Road, Balsall Heath, Birmingham, in the County of Warwick, Foreman of Works,
do hereby declare the nature of our invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
We will describe our invention as applied to the connecting of the terminal
ornament of a metallic bedstead to the top of the pillar of the same.
This connection is ordinarily effected by means of a screw at the top of the
pillar taking into a screw nut in the base of the ornament.
It frequently happens that an imperfection in the thread of the screw occasions
some difficulty in making the thread of the screw nut engage properly with the
said screw and the ornament when screwed home may not seat itself closely on thre
top of the pillar. In other cases the defective screw thread fails to properly. bind
or connect the ornament to the pillar and the ornament is consequently liable to
accidental detachment.
In attaching the ornament according to our invention we dispense with the
ordinary screw nut in the base of the ornament and substitute therefor an inverted
cup of the kind hereinafter described made of sheet steel or other elastic metal or
alloy. The said cup has a central opening of a size suitable to engage in the groove
of the screw of the bedstead pillar and two, three or other number of radial slits or
notches are made in the cup, which slits or notches pass into the central opening
described. The said slits or notches permit of the central opening in the cup being
slightly expanded and contracted. The said inverted elastic cup is connected to
the base of the ornament by burnishing or otherwise.
In attaching the ornament, its base containing the elastic cup is placed on the
end of the screw of the pillar and the said ornament turned exactly as if it con-
tained an ordinary screw nut. By the screwing motion of the ornament the edge
of the central opening in the elastic cup engages with the thread of the screw and
the continued turning of the ornament screws it home. When the base of the
ornament seats itself on the top of the pillar the further turning of the ornament
causes the thread of the screw to draw downwards the central part of the elastic
cup thereby somewhat flattening the said part and contracting the central opening
so as to make it bind tightly in the groove of the screw. The ornament can thus
be made to bind very tightly on the top of the pillar and it is scarcely possible for
the ornament to become detached accidentally.
Figure 1 of the accompanying Drawing represents in elevation a portion of the
corner pillar of a metallic bedstead with a terminal knob or ornament attached
thereto according to our invention, the said terminal knob being in section.

page_text: Figure 2 is a plan of underside of the said knob.
Figures 3 and 4 represent in plan and section respectively the inverted cup
which replaces in the terminal knob the ordinary tapped lead or other plug or nut
in the base of the knob.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
The said inverted oup is made by a stamping and piercing operation preferably
from thin sheet steel the cup a having a central opening 6 and radial slits c, c, c, c.
The edges of the parts of the cup a between the slits are raised to such height that
they approximately follow the spiral curve of the screw thread with which they are
to engage. The said inverted cup Figures 3 and 4 is fixed and retained in position
at the base of the knob d by the spinning of the neck of the knob d upon the
edge of the said cup a (see the section Figure 1) and the said cup is prevented from
turning in the said base of the knob by punching or raising teats or projections d³,
d, in the flange of the knob and in the flange or base of the cup or by
other means.
When a knob of the kind represented in Figures 1 and 2 is screwed in the
ordinary way onto the end screw e of the pillar the said knob d readily engages
with the said screw e and on the base of the knob, by the screwing action, seating
itself on the top of the pillar; the further screwing of the knob causes the slight
drawing downwards of the elastic parts of the cup a and the consequent contraction
of the hole b in the same on the screw. It will thus be understood that the knob
is very securely held in place and that the accidental detachment of the same is
practically impossible.
Our invention has the further advantage that the knobs are capable of accommo-
dating themselves to screws of different sizes.
We wish it to be understood that the said inverted cup may be made in one piece
with the knob.
Terminal ornaments of curtain rods, cornice poles and the ornaments of fenders
and other metallic articles may be connected in the manner herein before described
and illustrated with respect to the terminal ornament of the pillar of a metallic
bedstead.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that we
claim as our invention:-
The improvement hereinbefore described and illustrated in the accompanying
Drawing in the connecting of the terminal ornaments of metallic bedsteads and
other articles of metallic furniture to the pillars of the same, which improvement
is also applicable to other like purposes, the said improvement consisting in pro-
viding the base of the knob, ornament or the like with an inverted cup having a
central hole and a series of preferably radial slits the edge of the hole engaging
with the screw thread of the screw on the attachment of the knob or ornament to
the bedstead pillar or the like substantially as hereinbefore described and illustrated.
