Improvements in Connecting the Terminal Ornaments of Tubular
Cornice Poles and Picture Rods, which Improvements are also
Applicable to the Connecting of Terminal Ornaments to the
Pillars of Metallic Bedsteads and other Tubular Articles.
I, WILLIAM HENRY TONKS, Managing Director of Tonks Limited, of Moseley
Street, Birmingham, in the County of Warwick, Manufacturers do hereby declare
the nature of this invention to be as follows :-
My invention has for its object to effect a ready and firm connection of terminal
ornaments to tubular cornice poles and picture rods the pillars of metallic bedsteads
and other tubular articles; and consists of the construction and arrangements of
parts hereinafter described for that purpose.
I will describe my invention in connection with a cornice pole.
In the neck of the ornament and projecting from it a screw pin is fixed preferably
in the casting process by which the ornament is formed. A circular screw nut is
fitted on the said screw the edge of the said nut being inclined or conical, the end
of smaller diameter being turned towards the body of the ornament.
A binding piece consisting of a cruciform piece of sheet metal, the arms of which
are turned nearly at right angles to the central part is placed upon the screw pin
the said screw pin passing through a hole in the central part of the binding piece.
The inner ends of the arms of the binding piece are of such a diameter that when
the said binding piece is introduced into the end of the cornice pole it fits with
Bufficient tightness to prevent it from turning therein excepting by the application
of considerable force. After the binding piece has been forced home in the end of
the cornice pole the ornament is turned in the direction proper for driving home a
screw when the conical screw box is drawn on the screw and the binding piece
expanded so that the ends of its arms bear against the inside of the cornice pole
and fix the ornament in its place. The ornament may be fixed with any required
degree of tightness by drawing the conical screw box to a greater or less distance
on the screw. By turning the ornament in a direction contrary to that hereinbefore
indicated, its hold on the cornice pole is relaxed and it may be removed.
The binding piece, which is expanded within the cornice pole, may consist of a
hollow cone or split tube instead of a series of arms bent from sheet metal; and
the screw nut may be made to force back, on the rotation of the ornament, a split
tube or ring. In this modification a cone is used at the base of the neck of the
ornament and the split tube or ring by being forced upon the said cone on the
advance of the screw nut, is expanded and made to bear against the inside of
the cornice pole and fix the ornament.
The application of my improvements to the connecting of terminal ornaments to
picture rods and to the pillars of metallic bedsteads and to the ends of other tubular
articles differs in no essential respect from its application to the connecting of
terminal ornaments to cornice poles as hereinbefore described.

Improvements in Connecting the Terminal Ornaments of Tubular
Cornice Poles and Picture Rods, which Improvements are also
Applicable to the Connecting of Terminal Ornaments to the
Pillars of Metallic Bedsteads and other Tubular Articles.
I WILLIAM HENRY TONKS, Managing Director of Tonks Limited, of Moseley
Street, Birmingham in the County of Warwick, Manufacturers, do hereby
declare the nature of my invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
My invention has for its object to effect a ready and firm connection of terminal
ornaments to tubular cornice poles and picture rods, the pillars of metallic bedsteads
and other tubular articles; and consists of the construction and arrangements of
parts hereinafter described for that purpose.
I will describe my invention in connection with a cornice pole.
In the neck of the ornament and projecting from it a screw pin is fixed preferably
in the casting process by which the ornament is formed. A circular screw nut is
fitted on the said screw, the edge of the said nut being inclined or conical, the end
of smaller diameter being turned towards the body of the ornament.
A binding piece consisting of a cruciform piece of sheet metal, the arms of
which are turned nearly at right angles to the central part is placed upon the
screw pin, the said screw pin passing through a hole in the central part of the
binding piece. The inner ends of the arms of the binding piece are of such a
diameter that when the said binding piece is introduced into the end of the cornice
pole it fits with sufficient tightness to prevent it from turning therein excepting by
the application of considerable force. After the binding piece has been forced
home in the end of the cornice pole the ornament is turned in the direction proper
for driving home a screw when the conical screw box is drawn on the screw and
the binding piece expanded so that the ends of its arms bear against the inside of
the cornice pole and fix the ornament in its place. The ornament may be fixed
with any degree of tightness by drawing the conical screw box to a greater or less
distance on the screw. By turning the ornament in a direction contrary to that
herein before indicated, its hold on the cornice pole is relaxed and it may be
removed.
The binding piece which is expanded within the cornice pole, may consist of a
hollow cone or split tube instead of a series of arms bent from sheet metal; and
the screw nut may be made to force back, on the rotation of the ornament, a split
tube or ring. In this modification a cone is used at the base of the neck of the
ornament and the split tube or ring by being forced upon the said cone on the
advance of the screw nut, is expanded and made to bear against the inside of
the cornice pole and fix the ornament.
The application of my improvements to the connecting of terminal ornaments
to picture rods and to the pillars of metallic bedsteads and to the ends of other
tubular articles differs in no essential respect from its application to the connecting
of terminal ornaments to cornice poles as hereinbefore described.
I will now proceed to describe with reference to the accompanying drawing the
manner in which my invention is to be performed.
Figures 1 and 2 represent in side elevation, partly in longitudinal section, one of
the arrangements of my invention for connecting the terminal ornament to the
tubular cornice pole or picture rod, Figure 1 representing the binding piece in its
relaxed or normal position and Figure 2 representing the same in its expanded and
binding position against the inside of the pole or rod for fixing the ornament in its
place:

page_text: Figure 3 represents the combined binding piece and conical screw box apart
from the ornament and Figure 4 represents the screw box separately:
Figure 5 represents the cruciform sheet metal blank from which the binding
piece is made and
Figure 6 represents the partly made binding piece before the screw box is
applied to it.
The same letters of reference indicate the same parts in Figures 1, 2, 3, 4, 5
and 6.
b
a is the terminal ornament and 6 is the projecting screw pin of the same; c is
the screw nut fitted on the screw pin b, the edge of the said nut being conical or
inclined, the end of smaller diameter being turned towards the body of the
ornament a; d is the binding piece through a hole in the centre of which the screw
pin 6 passes. The binding piece d is made by bending the arms of the cruciform
blank Figure 5 at right angles to the perforated central part as represented in
Figure 6. After the blank has been thus fashioned, the conical screw nut c is
placed within the arms of the binding piece, and the inner ends of the said arms
are bent at right angles so as to prevent the said screw box from being separated
from the binding piece.
The inner ends of the arms of the binding piece d are of such a diameter that
when the said binding piece is introduced into the end of the cornice pole or
picture rod e it fits with sufficient tightness to prevent it from turning except by
the application of considerable force. After the binding piece d has been forced
home in the end of the pole or rod e and the collar a² of the ornament made to bear
against the said pole or rod as represented in Figure 1, the ornament a is turned
in the direction proper for driving home a screw. The conical screw box c is
thereby drawn on the screw pin 6 and the binding piece d expanded so that the
ends of its arms are forcibly pressed against the inside of the cornice pole or picture
rod as represented in Figure 2 and fix the ornament in its place. By turning the
ornament a in a direction contrary to that indicated the screw box e retires on the
screw pin band the pressure of the arms of the binding piece d on the inside of
the pole or rod is relaxed as represented in Figure 1 and the ornament may be
removed.
Figure 7 represents in side elevation, partly in section, and Figure 8 in cross
section, the arrangement of my invention in which the binding piece consists of a
split or divided tubular screw nut working upon the projecting screw of the
ornament: Figure 9 represents the same after the binding screw nut has been
expanded so as to fix the ornament in its place. In this arrangement the screw
pin of the ornament a is made conical and works in a screw box at the front of
the split or divided tubular binding piece f. The split or divided tubular binding
pieceffits tightly in the end of the pole or rod e. By turning the ornament u,
after the binding piece has been forced into the end of the pole or rod e, as
represented in Figures 7 and 8, the said binding piece advances on the screw pin
towards the wide end of the said screw pin. The slit or divided binding piece is
thereby expanded and made to bear forcibly against the inside of the pole or rod e
and fix the ornament in its place as represented in Figure 9.
Figures 10 and 11 represent the arrangement of my invention in which a cone is
used for expanding the binding piece, Figure 10 representing the binding piece in
its normal or unexpanded position and Figure 11 representing the same after it has
been expanded for fixing the ornament.
In this arrangement, a divided ring 9, is used in place of a divided tubular
binding piece, the said ring a being situated on the cone at the base of the
ornament a, a tubular screw nut i on the screw pin b being used for forcing back
the split ring 9 on the cone h and expanding it. That is to say, after the ornament a
carrying the screw pin b, cone h divided ring 9 and screw nut i, has been placed
in the end of the pole or rod e, the ornament a is rotated so as to cause the tubular
screw box i to advance on the screw pin b. The front edge of the said screw
box i is thereby made to force the divided ring 9 upon the cone h, expanding

page_text: it and causing it to bear forcibly against the inside of the pole or rode and fix
the ornament in its place as represented in Figure 11.
I apply my invention to the connecting of terminal ornaments to the pillars of
metallic bedsteads and to the ends of other tubular articles substantially in the
manner herein before described and illustrated with respect to the terminal
ornaments of cornice poles and picture rods.
-
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that
my invention of
