Improvements in Means for Securing Loose or Fitted Terminals or
Ends to Picture, Curtain, Cornice, Stair, and other analogous
Rods and Tubular Articles.
I, GEORGE THOMAS PIGGOTT of the Firm of Williams Brothers and Company,
of River Street, in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in means for securing loose or fitted
terminals or ends to hollow rods or poles and tubular articles, such for example as
picture, rods, curtain rods, desk rods, stair rods, cornice poles, portiere rods,
bedstead mounts and the like, and has for its object, a simple, efficient, and cheaply-
produced means of attachment.
In carrying out my invention in connection with any ordinary rod, the en ord
terminal has upon its inner side, a centrally disposed screw pin or shank, which
takes axially through a diagonally split or divided plug or stopped, with the axial
hole in the outer section being plain and having slight lateral play upon the pin,
and the hole in the inner section being screwed, so that when the terminal is rotated
for affixing, the wormed end of its stem or stalk screws into and travels up the after
section of the plug, and as the foot of the terminal impinges against the outer end
of the outer section, the relative length of the plug is diminished, and the inclined
plane of the outer section is made to slide up the opposed inclined plane of the inner
or after section, (which has a back traverse upon the shank or pin) and the said
outer plug is made to be displaced relatively and become excentric and to forcibly
impinge itself against the inside bore of the tube, hence the locking or jambing of
the terminal or end within the bore of a rod.
Thus, the screwing home of the terminal or end pulls the inner section of the
plug towards the foot or collar of the said end, and so forces its inclined plane
upon that of the outer section, which is laterally displaced and becomes excentric
to the axis of the terminal hence the gripping of the opposite inner walls of a tube
by the respective sections of the plug.
Instead of employing two sections, a plug may be made up of three or more
scctions, which may be made of cast or sheet metal.
The application of my invention to bedstend and like mounts and terminals
differs in no essential respect from its application to the securing of terminals or
ends to picture and like rods, as herein described.

Ends to Picture, Curtain, Cornice, Stair, and other analogous

I. GEORGE THOMAS PIGGOTT, of the Firm of Williams Brothers and Company,
of River Street, in the City of Birmingham, Manufacturer, 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 improvements in means for securing loose or fitted
terminals or ends to hollow rods or poles and tubular articles, such for example as
picture rods, curtain rods, desk rods, stair rods, cornice poles, portiere rods,
bedstead mounts and the like, and has for its object, a simple, efficient, and
cheaply-produced means of attachment.
In carrying out my invention in connection with any ordinary rod, the end or
terminal has upon its inner side, a centrally disposed screw pin or shank, which
takes axially through a diagonally split or divided plug or stopper, with the axial
hole in the outer section being plain and having slight lateral play upon the pin,
and the hole in the inner section being screwed, so that when the terminal is rotated
for affixing, the wormed end of its stem or stalk screws into and travels up the after.
section of the plug, and as the foot of the terminal impinges against the outer end of
the outer section, the relative length of the plug is diminished, and the inclined plane
of the outer section is made to slide up the opposed inclined plane of the inner or after
section, (which has a back traverse upon the shank or pin) and the said outer plug is
made to be displaced relatively and become excentric and to forcibly impinge itself
against the inside bore of the tube, hence the locking or jambing of the terminal or
end within the bore of a rod.
Thus, the screwing home of the terminal or end pulls the inner section of the plug
towards the foot or collar of the said end, and so forces its inclined plane upon that
of the outer section, which is laterally displaced and becomes excentric to the axis
of the terminal, hence the gripping of the opposite inner walls of a tube by the
respective sections of the plug.
Figure 1 of the accompanying drawing represents a horizontal section of the
means of connection between a curtain rod and its terminal constructed according
to this form of my invention.
Figure 2 is a transverse vertical section of Figure 1 upon the dotted liner—t,
and Figure 3 is a like section upon the dotted line A Figure 1.
In Figures 1, 2 and 3, a is the terminal or end ornament, having upon its inner
face a', a central and screwed stalk or pin a, taking axially through the diagonally
split or divided sections 1, 2 of the plug b, located within the interior of the end c¹,
of the rod c, and forming the connection between it and the terminal.
The axial hole 63 in the outer section 1, of the plug or connection is plain, and
is sufficiently large as to admit of the said section having a slight lateral play upon
the stalk, but the hole, in the inner section 2, is wormed throughout its length
to correspond with the screw thread upon the said stalk, so that after the connection
means has been inserted within the end of a rod and the stalk of the terminal passed
through the plain hole 63 of the incline-plane-faced section 6, and the rotation of
the said stalk a* into the screwed hole of the inner section ", the said section is
slightly drawn towards the terminal inclined face , of the outer section is made
to travel up the like and opposed inclined face, of the inner section, and so that
both sections are made forcibly to impinge against the inside of the tube, hence a
jambing connection of the terminal with the rod.

page_text: The gripping faces 67, 68, of the sections are serrated or toothed to ensure a better
grip or bite.
Instead of one of the sections being wormed, both of them may have plane holes
and the screwed stalk of the terminal may pass through them and take into a
non-rotating screw nut.
Figure 4 represents a longitudinal section of such a connection.
Figure 5 is a transverse vertical section of Figure 4 upon the dotted line B.
Figure 6 is a section of the outer section of the plug connection.
Figure 7 is an underside plan, Figure 8 is a section and Figure 9 an end view of
the inner section, which is gapped at the back to receive the non-rotating nut
represented in Figures 10 and 11 respectively in section and end view.
In Figures 5 to 11, a is the terminal, c the rod, and 61, 62, the sections of the
connection b, the axial holes 63, 4 through which are plain and sufficiently large
in bore to have slight play upon the screwed shank a², of the terminal, which passes
directly through them and whose screwed end a³, takes into the non-rotating nut d,
located within the cross sinking 6, formed to receive it at the back of the inner
section 6, of the plug.
By rotating the terminal and its stem, the screwed end worms itself into the nut,
whereby the inclined sectional parts of the connection are forced asunder laterally,
by the reciprocal sliding of the incline planes of the sections upon one another,
whereby the roughened or serrated faces 67, 68, are made to forcibly impinge against
the inside of the rod, hence the connection.
Figure 12 represents my invention applied as a connection between two lengths
of tubing.
a is a coupling, having a double stalk a², which pass through connections b,
located within the ends c', of hollow rods c, which connections have a like action
and are marked with the same letters of reference as in Figures 4 to 11.
Instead of employing two sections, a plug or connection may be made up of three
or more wedge-faced sections, which may be made of cast or sheet metal.
The application of my invention to bedstead and like mounts and terminals differs
in no essential respect from its application to the securing of terminals or ends to
picture and like rods, as herein described.
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 :-
First. A connection for the knobs or terminal ends of curtain rods and the like,
consisting of a sectional plug, with the sections having opposed inclined planes,
and with a screwed stem of the terminal passing through a plain hole in the one
section and a screwed hole in the other, substantially as described and set forth in
Figures 1, 2 and 3.
Secondly. A connection for the knobs or terminal ends of curtain rods and the
like, consisting of a sectional plug, with the sections having opposed inclined planes
and with a screwed stem of the terminal passing through plain clearance holes
formed through both sections and taking into a non-rotating screw nut, or into a
nut located within a sinking formed within the inner section, substantially as
described and set forth in Figures 4 to 11.
