Improvements in the Manufacture of Metal Tubes for use as Cornice
Poles, Curtain Rods, and for other purposes.
I, TOM HOLLAND LAWTON, of 772, Coventry Road, Birmingham, in the County
of Warwick, Brass Founder, 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 the manufacture of metal tubes of circular or other
form in cross section for use as cornice poles, curtain rods, and also for other
purposes. It consists of forming the tube for the pole or rod as the case may be in
two longitudinal sections; one section being of finished brass or other suitable
ornamental metal, and the other section of a baser metal such as zinc or iron, or
of inferior or unfinished brass. A pole or rod thus constructed when in position
with the ornamental section outward will have the same appearance and durability
as an ordinary metal pole or rod at present in use, but the cost of production is
considerably less.
My invention will be easily understood upon reference to the accompanying
drawings, in which,―
Figure 1, is a transverse section of a tubular pole with the two parts jointed
together.
Figure 2, shews sections of the two parts of the pole before they are jointed
together.
Figures 3, 4, 5 and 6, shew tubes of various forms in cross section constructed
according to this invention.
In carrying out my invention I form two channel shaped sections (A) and (B);
the section (A) being preferably of brass and the section (B) of zinc or other
inferior metal. For poles or rods (Figures 1 and 2) the section (A) is made a
little larger than the section (B) in order that the tube when complete may consist
more of the ornamental or finished part than the unfinished or inferior part, as a
greater portion of the circumference of a pole is seen, when in position, than is
obscured. The two sections are fastened together by means of overlap joints.
These joints are formed by turning in the longitudinal edge portions of section (A)
and turning up those of section (B) or vice versa.
The two sections are now placed together to form a tube; a steel mandril or
other suitable tool is then inserted therein, and the whole is drawn through a die
to force the joining edges tightly together.
The transverse section of the pole or rod may be formed of any suitable shape
or pattern as shewn by way of example in Figures 3, 4, 5 and 6.
With the addition of an internal iron stiffening tube or bar, tubes constructed
according to this invention can be used for fender rails and stair rods; in this
case the inferior section of the tube will be placed in the obscure position.
Ornamental ends may be secured to the pole or rod when necessary in the usual
and well known manner.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
Firstly. The construction of metal tubes in two longitudinal sections (A)
and (B), jointed together, substantially as and for the purposes herein set forth.
Secondly. The construction of metal tubes of circular or other form in cross
section substantially in the manner and for the purposes as herein set forth and
as illustrated.
