PROVISIONAL SPECIFICATION.
Improvements in Ornamenting Brass or other Metallic Tubing.
We, JOSEPH WALKER and EDGAR FRANK ATKINS, both of Regent Place,
in the City of Birmingham, Brassfounders, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to a method of ornamenting brass or other metallic tubing
and its object is to produce a handsome tube without pattern but having the sides
of the said tubing so contorted as to produce a decorative and massive effect.
In carrying our invention into effect as applied to square brass tubing we may
bend the tube in two directions as to produce a wavy or sinuous outline whichever
way the tube may be turned. This effect we produce by stamping the tube
between dies of the desired configuration first stamping in one direction and then at
or near right angles to it. Or we may pass the tube through rolls with suitable
projections and depressions to bend the tube; two pairs of rolls may be used acting
at right angles to each other, the axis of one pair at a sufficient distance from the
axis of the other pair. Round tube may be treated in the same way as we have
described for square tube.
In ornamentation of the kind hereinbefore described the tube practically
preserves its original section at any part, that is, the tube is waved without
changing the section. In another effective style of ornamentation produced by
similar means we force in opposing sides of a square tube and thus force out the
opposing sides at right angles to it, and this we arrange alternately so that any
particular face of the square consists of a series of hollows and projections but the
tube is not waved in outline. It preserves its general straight outline with
reticulations or alternate hollows and projections. This pattern may be produced
either by rolls or by stamping or pressing, the rolls if two pairs be used being
arranged in succeeding planes.
When the configuration is stamped we prefer to set the square tube in the dies
diamond wise and then our dies can be shaped to produce the effect on the four
sides simultaneously. We can also roll this section diamond wise by suitable rolls.
The same devices may be applied to round tubing.

Improvements in Ornamenting Brass or other Metallic Tubing.
We, JOSEPH WALKER and EDGAR FRANK ATKINS, both of Regent Place,

invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention relates to a method of ornamenting brass or other metallic tubing
and its object is to produce a handsome tube without pattern but having the sides
of the said tubing so contorted as to produce a decorative and massive effect.
Referring to the accompanying sheet of drawings—
Figure 1 shows in elevation a tube so contorted or bent.
Figure 2 is a corresponding transverse section.
Figures 3 and 4 illustrate in elevation a tube ornamented in a like manner.
Figures 5 and 6 are transverse sections corresponding to Figures 3 and 4.

page_text: Figures 7 and 8 are elevations similar to Figures 3 and 4 and
Figures 9 and 10 are transverse sections corresponding to Figures 7 and 8.
In carrying our invention into effect as applied to square brass tubing we may
bend the tube in two directions so as to produce a wavy or sinuous outline which-
ever way the tube may be turned. This effect we produce by stamping the tube
between the dies of the desired configuration first stamping in one direction and
then at or near right angles to it. Or we may pass the tube through rolls with
suitable projections and depressions to bend the tube; two pairs of rolls may be
used acting at right angles to each other, the axis of one pair at a sufficient distance
from the axis of the other pair. Round tube may be treated in the same way as
we have described for square tube.
A square tube so treated is shown at Figure 1 and here it is to be observed the
depression A on one side has on the other side the bent out side B and the
depressed or concave side D) is likewise opposed by the convex side C. The tube
is similarly bent at right angles to the position shown in Figure 1, so that which-
ever way it be turned the same configuration as that shown in Figure 1 will be
presented.
In ornamentation of the kind hereinbefore described the tube practically
preserves its original section at any part, that is, the tube is waved without
changing the section. At all points of the tube therefore the cross section is as
shown at Figure 2.
In another effective style of ornamentation produced by similar means we force
in opposing sides of a square tube and thus force out the opposing sides at right
angles to it, and this we arrange alternately so that any particular face of the
square consists of a series of hollows and projections but the tube is not waved in
outline. It preserves its general straight outline with reticulations or alternate
hollows and projections. This pattern may be produced either by rolls or by
stamping or pressing, the rolls if two pairs be used being arranged in succeeding
planes.
Tubes so treated are illustrated in elevation at Figures 3, 4, 7 and 8. The
elevations Figures 3 and 4 are at right angles to each other so also are Figures 7
and 8. At the lines ab Figures 3 and 7 the opposing sides are shown forced in
thus forcing out the sides at right angles as shown at c d Figures 4 and 8. The
transverse sections a Figures 5 and 9 correspond to the positions a b Figures 3
and 7, while the similar sections c d correspond to c d Figures 4 and 8.
When round tube is treated the effect shown at Figures 3 and 4 is produced;
but when square tube is treated that shown in Figures 7 and 8 appears.
When the configuration is stamped we prefer to set the square tube in the dies
diamond wise and then our dies can be shaped to produce the effect on the four
sides simultaneously. We can also roll this section diamond wise by suitable rolls.
The same devices may be applied to round tubing.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. Ornamenting brass or other tubing by forcing in one side and forcing out the
opposing side or bending as hereinbefore described with reference to Figures 1
and 2 of the drawings.
2. Ornamenting brass or other tubing by forcing in opposing sides, thus also
forcing out opposing sides as herein before described with reference to Figures 3,
4, 5, 6, 7, 8, 9 and 10 of the drawings.
