A New Method of Forming Ornamental Terminals on Hollow Stair
Rods.
We, THOMAS ROBERT WRIGHT, GEORGE JONES, SAMUEL ROBINSON, and SAMUEL
DUNN, trading as T. R. Wright and Co., of Leach Street, Birmingham, in the
County of Warwick, Stair Rod Manufacturers, do hereby declare the nature of
this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
-
Our invention has for its object a new method of forming ornamental terminals
on hollow stair rods of brass and other such material and refers particularly to
the method of forming ornamental terminals on either seamless drawn tubes or
those having soldered joints whereby such terminals are formed in one with the
tube in such a manner as to strengthen the terminal and at the same time cheapen
the cost of production in comparison with those having separate ends which
require to be attached to the tubes by soldering.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto one sheet of drawings upon which we
have fully illustrated the nature of our said improvements.
Figure 1 is a view of a short length of seamless drawn or soldered tube from
which the rods are formed.
Figure 2 is a section through the tools when in position for operating upon the
tube to form the terminal.
Figure 3 is a similar section to Figure 2 but shewing the tools in course oi
operation.
Figure 4 is a view of the back of one end of a rod after being pressed by the
tools.
Figure 5 is a side elevation of Figure 4.
Figure 6 is a similar view to Figure 4 but shewing the terminal after being
cut to the required shape or configuration.
Figure 7 is a side elevation of Figure 6.
Figure 8 is an end elevation of Figure 6.
Figure 9 is an end elevation similar to Figure 8 but shewing the terminal
formed upon a modified section of tube.
Figures 10 11 and 12 are also end elevations showing further modifications in
the section of the tube.
In carrying out our invention into effect we take the solid drawn or soldered
brass or other tube A which has been previously cut to the required length for
the stair rod and subject the end after annealing to the pressure of the specially
shaped tool B which presses the sides of the tube inwards as shewn at Figure 3
until it takes the formation shewn by Figures 4 and 5 in which the centre metal
of the tube is pressed into the ridge a which forms a strengthening flange to
the flattened end of the rod. The end after being thus pressed is placed between
suitable cutting tools by which it is cut to the required shape such as shewn in
Figure 6. Each end of the rod is similarly treated and our improvement is

page_text: equally applicable to solid drawn or soldered tubes of other sections as for
example in the case of Figure 9 where the face of the tube is convex instead
of flat or Figure 10 in which the face is shown angular or Figure 11 in which
the face is shown concave and Figure 12 where bevelled edges at are provided to
the face and many other sections which entail only slight alterations in the
shape of the tools.
We may find it convenient after pressing the terminal to slightly solder the
extreme end of the ridge and face together and in some cases where the ter-
minal end buckles in the cutting process we may again press it between the
tools B and B for the purpose of straightening it.
The shape to which the terminal is cut may be varied to any extent and in
some cases we may prefer to form two strengthening ridges a slight distance
apart instead of the central ridge a¹.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is: : -
1st. Forming ornamental terminals on stair rods of solid drawn or soldered
tubing of triangular or similar sections by pressing and cutting the ends of
the tube substantially as and for the purpose herein set forth and illustrated.
Dated this 19th day of September 1899.
