Improvements in Metal Tubes.
ROBERT OSMAN STYLES of 96 Sandringham Road Dalston in the County of
Middlesex Gentleman and FRANCIS WHEELER-BROWN of 56 Rectory Road Stoke
Newington in the same County Surgeon do hereby declare the nature of this inven-
tion to be as follows
This Invention relates to improvements in metal tubes; it has for its object the
improved construction and strengthening of ordinary hollow metal pipes or tubes
now in use as for instance in the construction of velocipedes, carriages, roof ties
or for any other purpose where strength and lightness may be required.
In carrying out this invention we insert longitudinally, in any pipes or tubes of
ordinary construction, triangular, cross, or star shaped metal rods of the same length
as the tubes to be dealt with and of an outside form and diameter to exactly fit
the interior circumference or bore of such ordinary pipes or tubes or (alternatively)
we insert in ordinary pipes or tubes bundles or groups of three or more smaller
tubes of similar length arranged side by side and of such aggregate diameter as will
enable the bundle or group of small tubes to be firmly fixed to the inner circumference
or bore of the ordinary or outer pipe or tube.
The metal rods employed by us are shaped in such a manner as to divide the
interior of the outer or ordinary tubes encasing them into three, four or more
separate longitudinal cells throughout their entire length.
The bundles or groups of small tubes are arranged in the interior of the outer
or ordinary tubes encasing them in such a manner as to divide the interior of
such outer tubes into seven, ten or more separate longitudinal cells throughout their
entire length.
The shaped rods or the groups of small tubes are solidly fixed in the interior of
the outer or ordinary tubes and to each other by heat or other usual means, or.
(alternatively) tubes may be drawn in one piece with either of the arrangements of
longitudinal cells herein described by any of the usual means now employed for
drawing solid steel or other tubes.

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. In metal tubes such as described the insertion and fixing of triangular, cross or
star shaped metal rods longitudinally substantially as described.
2. In metal tubes such as described the insertion and fixing of bundles or groups of
smaller tubes longitudinally substantially as described.
3. The drawing in one piece of solid metal tubes formed with longitudinal sections
throughout their length substantially as described.
