Improvements in Tubular Rod End Fastenings.
I, JOHN HOWARD CARTLAND, of Constitution Hill, in the City of Birmingham,
Brassfounder, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improvements in fastenings for securing the ends or
terminals of tubular rods, such for instance as for picture rods, cornice poles, or
other similar fittings, and may be applied for the junction of one tube to another
or for securing the usual terminal fitting.
My invention admits of variation in shape without departing from its nature.
The present or commoner method of these attachments is by providing a central
projecting screw in the terminal, or in the part to be attached, which takes into a
wooden plug which has been driven tightly into the tube to which it is to be
attached. Now one of the objects of this my invention is to provide a fastening
which may be readily applied to such existing terminal screws, and so to remove
the wooden plug. Or it may of course be made and supplied upon such screws or
equivalent studs or pegs, and removable therefrom or rigidly secured thereto.
I take a strip of steel (or other suitable material) and bend and shape it so that
a portion of it may clip and firmly hold the central screw or stud, while the
remainder is formed into a springy expanding band, which will bind itself against
the interior of the tube. Thus the width of the strip forms the depth or length of
the fastening inside the tube. The precise manner of this shaping or bending may
vary, inasmuch as that the end of the said strip may be made to clip the pin or
screw, or the central part of such strip may be made to do so.
In some cases, I may cut slits in the strip and push outwards such slitted portions,
so as to present a more or less jagged surface thereon, to increase the holding effect
with the tube. If desired this fastening may be more securely attached to the
central pin, by using a screw nut at the end of the screw, or by rivetting &c.

I, JOHN HOWARD CARTLAND, of Constitution Hill, in the City of Birmingham,
Brassfounder, 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 fastenings for securing the ends or
terminals of tubular rods, such for instance as for picture rods, cornice poles, or
other similar fittings, and may be applied for the junction of one tube to another
or for securing the usual terminal fitting.
My invention admits of variation in shape without departing from its nature.
The present or commoner method of these attachments is by providing a central

page_text: projecting screw in the terminal or in the part to be attached, which takes into a
wooden plug which has been driven tightly into the tube to which it is to be
attached. Now one of the objects of this my invention is to provide a fastening
which may be readily applied to such existing terminal screws, and so to remove
the wooden plug. Or it may of course be made and supplied upon such screws or
equivalent studs or pegs, and removable therefrom or rigidly secured thereto.
In order to more clearly explain this my invention I have appended hereunto an
illustrative sheet of drawings upon which are figures and numbers of reference,
similar numbers referring throughout to the same thing or part.
Fig. I is a side view of this my invention as applied to a terminal.
Fig. 2 is a cross sectional view of the fastening upon line A-B.
Fig. 3 shows the application of this my invention to a cornice pole or other
similar fitting.
Fig. 4 is a side view of a modified shape of the fastening, and Fig. 5 is a cross
sectional view of this modified shape on line C―D.
I take a strip of steel (or other suitable material) and bend and shape it so that
the portion 7 of it, may clip and firmly hold the central screw or stud 8, while the
outer part 9 is formed into a springy expanding band, which will bind itself against
the interior of the tube to which it is to be attached such as 10. Thus the
width 11-12 of the strip forms the depth or length of the fastening inside the said
tube. The precise manner of this shaping or bending may vary, inasmuch as shown
in Figs. 4 & 5 the end 13 of the said strip may be made to clip the pin or
screw 8, or the central part of such strip may be made to do so, as shown in
Figs. 1, 2 & 3.
In some cases, I may cut slits in the strip, and push outwards such slitted portions,
so as to present a more or less jagged surface thereon, to increase the holding effect
with the tube. If desired this fastening may be, more securely attached to the
central pin, by using a screw nut 14 see Fig. 3 at the end of the screw, or by
rivetting &c.
By reason of the screw thread upon the pin 8, and the tight binding of the
part 7 and 13 thereon, and by indenting the metal as seen at 15, or by turning
down a small portion of the edge of the metal as seen at 16, into the thread of
the screw, the nut 14 is rarely needed.
By these means a very simple fastening is made which is yieldable for entrance
into any suitable tube, and affords a good holding surface contact longitudinally,
and partly if not entirely circumferentially with such tube, and at the same time
permits of ready application to the usual method of manufacturing terminals &c.
with an ordinary central screw.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The fastening for tubular terminals and the like, constructed and operating
substantially as herein described and illustrated in Figs. 1, 2 & 3 or such
modification as shown and described in Figs. 4 & 5.
