An Improvement or Improvements in Connecting Terminal
Ornaments to the Ends of Metallic Tubular Curtain Rods
and Cornice Poles, and to the Pillars of Metallic Bedsteads,
2 and to Metallic Tubes for other purposes.
We, EVERED AND COMPY. LIMITED, of Barnet Works, Birmingham in the
County of Warwick, Manufacturers and GEORGE CLARKE, Works Manager at
Barnet Works Birmingham, aforesaid do hereby declare the nature of this invention
to be as follows:
The object of the said invention is to connect in a simple and efficient manner
the terminal ornaments of metallic tubular curtain rods and cornice poles and the
pillars of metallic bedsteads and other metallic tubular articles to the ends of the
said articles as hereinafter described.
We will describe the said invention in connection with a curtain rod.
To the shoulder of the ornament we attach an elastic nearly tubular piece formed
in the following manner. We cut from thin sheet steel or other elastic metal or
alloy a disc having about three times the diameter of the interior of the end of the
curtain rod, the said disc having a series of radial slits made in its marginal portion
The said arms
so as to form the said marginal portion into a series of radial arms.
are bent nearly at right angles to the central portion and the free ends of the said -
arms are made slightly convex externally. There is thus formed a spring having
the general figure of a tube closed at one end and slightly bulbous at its open end and
having slits parallel with its axis. The extreme end of the slitted tube is slightly
less in diameter than the interior of the end of the curtain rod. The compound
spring thus made is connected by its central part by a screw or otherwise to the
shoulder of the ornament and in order to attach the ornament to the end of the
curtain rod it is only necessary to present the open end of the spring to the open
end of the curtain rod and to press the ornament in the direction of the line of the
axis of the tube. The bulbous end of the spring is compressed as the spring enters
the tube and by its elasticity holds the ornament when pressed home with great
firmness. For additional security the end of the tube may be slightly contracted.
In this case the spring when the ornament is pushed home expands and offers greater
resistance to the removal of the ornament than when the end of the tube is not
contracted.
The application of the said invention to the connecting of the terminal ornaments
to the ends of metallic tubular cornice poles, the pillars of metallic bedsteads and
metallic tubes for other purposes differs in no essential respect from its application
to the connecting. of the terminal ornaments to the ends of a metallic tubular
curtain rod as hereinbefore described.

An Improvement or Improvements in Connecting Terminal
Ornaments to the Ends of Metallic Tubular Curtain Rods
and Cornice Poles, and to the Pillars of Metallic Bedsteads,
and to Metallic Tubes for other purposes.
We EVERED AND COMPY., LIMITED of Barnet Works Birmingham, in the
County of Warwick Manufacturers, and GEORGE CLARKE Works Manager at
Barnet Works, Birmingham aforesaid, 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 :-
The object of the said invention is to connect in a simple and efficient manner
the terminal ornaments of metallic tubular curtain rods and cornice poles and the
pillars of metallic bedsteads and other metallic tubular articles to the ends of the
said articles as hereinafter described.
We will describe the said invention in connection with a curtain rod.
To the shoulder of the ornament we attach an elastic nearly tubular piece formed
in the following manner. We cut from thin sheet steel or other elastic metal or
alloy a disc having about three times the diameter of the interior of the end of the
curtain rod, the said disc having a series of radial slits made in its marginal portion
so as to form the said marginal portion into a series of radial arms. The said arms
are bent nearly at right angles to the central portion and the free ends of the said
arms are made slightly convex externally. There is thus formed a spring having
the general figure of a tube closed at one end and slightly bulbous at its open end
and having slits parallel with its axis. The extreme end of the slitted cup like
spring is slightly less in diameter than the interior of the end of the curtain rod.
The central part of this compound spring is connected by a screw or otherwise to
the shoulder of the ornament and in order to attach the ornament to the end of the
curtain rod it is only necessary to present the open end of the spring to the open
end of the curtain rod and to press the ornament in the direction of the line of the
axis of the tube. The bulbous end of the spring is compressed as the spring enters
the tube and by its elasticity holds the ornament when pressed home with great
firmness. For additional security the end of the tube may be slightly contracted.
In this case the spring when the ornament is pushed home expands and offers
greater resistance to the removal of the ornament than when the end of the tube is
not contracted.
Figure 1 of the accompanying drawing represents, partly in elevation and partly
in section a portion of a metallic tubular curtain rod and terminal ornament, the
said terminal ornament being connected to the end of the said tubular rod according
to the said invention;
Figure 2 represents the same before the terminal ornament is connected to the
said tubular rod, and Figure 3 is a cross section taken on the line a, a Figure 2:
Figures 4, 5, 6, 7 and 8 represent the various stages of manufacture by which
the spring connection hereinafter described of the terminal ornament is produced.
The same letters of reference indicate the same parts in the several figures of the
drawing.
a is the metallic tubular rod and b the terminal ornament of the said rod. The
said terminal ornament 6 is connected to the said tubular rod a by the spring
connection c, the said spring connection consisting of a slitted cup like spring made
in the manner hereinafter described, the free or open end of which is slightly
bulbous. The said spring connection c is secured to the terminal ornament b
preferably by the screw d, but other methods of securing the said cup like spring c
to the terminal ornament 6 may be employed. The extreme end of the cup like
.spring c is slightly less in diameter than the internal diameter of the tubular rod a,

page_text: but the largest diameter, or the diameter of the bulbous part of the said slitted
tube c, is greater than the internal diameter of the said tubular rod a.
The terminal ornament 6 with its cup like spring c is applied to the tubular rod a
by introducing the said spring c into the open end of the said rod a and pressing
the terminal ornament b so as to force the said spring c into the said tubular rod a.
The bulbous end of the spring c is thereby compressed as it enters the end of the
tubular rod a and by the elasticity of the arms of the said spring c the terminal
ornament 6 when pressed home is held with great firmness.
The cup like spring c of the terminal ornament 6 is made in the following
manner.
A disc of thin sheet tempered steel or other hard and ductile metal or alloy,
represented in plan and edge view in Figure 4, is taken and by cutting away from
the marginal part of the said disc a series of radial portions a series of radial arms c²
is formed as represented in plan and edge view in Figure 5. The said arms e² are
by a pressing operation bent so as to form with the central portion an angle of about
one hundred and twenty degrees as represented in elevation, section and plan in
Figure 6. By a further pressing operation the said arms c are brought to nearly
a right angle with the central part as represented in elevation section and plan in
Figure 7 and a hole c³ is pierced in the said central part for the screw d to pass
through when connecting the spring c to the terminal ornament b as hereinbefore
described. The free ends of the arms c² are made slightly convex as represented in
elevation and plan in Figure 8 thereby giving to the open or slitted end of the cup
like spring c the slightly bulbous figure hereinbefore referred to.
The application of the said invention to the connecting of the terminal ornaments
to the ends of metallic tubular cornice poles, the pillars of metallic bedsteads and
metallic tubes for other purposes differs in no essential respect from its application
to the connecting of the terminal ornaments to the ends of a metallic tubular curtain
rod as hereinbefore described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that we
claim as the said invention of "An improvement or improvements in connecting
terminal ornaments to the ends of metallic tubular curtain rods and cornice poles
and to the pillars of metallic bedsteads and to metallic tubes for other
purposes
""
Providing the end of the terminal ornament to be connected to the tubular rod
with a slitted cup like spring made from a disc of thin sheet tempered steel or other
hard and ductile metal or alloy as hereinbefore described, the said spring having a
slightly bulbous figure at its free or open end which when the said spring is forced
into the open end of the tubular rod is compressed thereby firmly securing the
terminal ornament to the said tubular rod substantially as hereinbefore described
and illustrated in the accompanying drawing.
