PROVISIONAL SPECIFICATION.
Improvements in and relating to the Manufacture of Tubes for Use
in the Construction of Cycles and other suitable purposes.
We WILLIAM AMES and WALTER STOKES trading as Ames & Stokes of
Hanley Works Hanley Street Birmingham in the County of Warwick,
Manufacturers, do hereby declare the nature of this invention to be as
follows:-
This invention refers to means whereby we are able to produce tubes such as
are known as of a D section for use in the construction of the frames of cycles,
though we can apply similar means for turning out tubes of any other section as
may be required.
For our purpose we arrange a pair of rolls suitably supported upon a bed which
work above and below each other by suitable motive power the lower roll has a
semi-circular groove in same when D section tubes are to be made, the upper roll
being a plain one, a mandril of the same section as the tube to be shaped comes
between the rolls a certain distance carried by a back centre which has a hand-
wheel at its rear to regulate the action. The operation is performed thus, we take
a round tube and place it upon the end of the mandril between the rolls and it is
drawn over the said maudril by the action of the rolls, thus giving to the tube the
required section, the tube as it passes through the rolls is checked by a gauge upon
the mandril when the required length has been shaped, the hand wheel of the back
centre is then turned and the action of the rolls reversed and the tube is turned off
from the machine.
According to the section of tube to be made so accordingly will the roll or rolls
be formed likewise the mandril.
By these means we are able to make tubes of a D or other section without the
necessity of loading the same with lead or sand before shaping as hitherto,
moreover we can turn them out very much quicker, and with a saving of cost and
labour.

Improvements in and relating to the Manufacture of Tubes for Use
in the Construction of Cycles and other suitable purposes.
We WILLIAM AMES and WALTER STOKES trading as Ames & Stokes,

Manufacturers, 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

page_text: by the following statement reference being had to the draivings accompanying this
specification and to the figures and letters shewn thereon:-
Our invention refers to means consisting of suitably arranged rolls, and guide
wheels, and a mandrel, in connection with machinery of any suitable description
whereby we are able to produce tubes, such as are known as of a D section, for
use in the construction of the frames, and other parts of cycles, and for other
suitable purposes, we can apply similar means for turning out tubes of any other
section as may be required by employing suitable rolls.

with our
For our purpose we arrange a pair of rolls A. B. suitably, supported by
bearings C. of a machine D, upon the bed D', said rolls work above and below
each other as shewn, driven by suitable motive power, pulley banding. E, and
suitably adapted pulley wheels E E2, and gear wheels E3 E, the lower roll B, is
formed with a semi-circular groove B' around its circumference, when the D section
tubes are to be made, the upper roll A being a plain one, projecting between the
rolls is a mandrel F, of suitable section supported horizontally by a back centre G,
and holder G¹, screw threaded so that the said back centre G, and holder G¹, can
be adjustably connected along the bed D¹, by screw pin H taking into holes H',
in said bed according to the length of tubing being rolled.
A guide wheel I, is situated and carried by upright I, in front of the rolls A. B.
as also guide wheels at J, J, behind said rolls suitably supported by J², as shewn
in dotted lines Figure 1 and elevational view Figure 4.
The operation is performed as follows. We take a round tube of the required
diameter, and pass it over the guide wheel I, and upon the projecting end of the
mandrel F, between the rolls A. B. said tube is drawn over the said mandrel, by
the action of the rolls, thus giving to the tube the required D section, the tube as
it passes through the rolls is checked, according to the length, by a gauge or
stop K, upon the mandrel F, when the required length has been shaped the action
of the rolls is then reversed by any well known, or other suitable means, and the
tube is drawn back, and turned off from the mandrel of the section shewn at
Figure 5.
According to the section of tube to be made, the roll or rolls, will be formed to
correspond, the mandrel may be preferably of a square section, or diamond shaped,
or half round.
By these means we are able to produce tubes of a D or other section, without
the necessity of loading the same with lead, or sand, before shaping, as hitherto
has been the practice, moreover, we can turn them out very much quicker and
with an obvious saving of labour and cost.
Having now particularly described and ascertained the nature and object of our
said invention and in what manner the same is to be performed we declare that
what we claim is :-
Firstly. In the manufacture of tubes of a D or other section, the employment
of suitably arranged and constructed rolls, guide wheels in connection therewith, a
mandrel suitably supported by back centre, or other means, and located horizontally
between said rolls, and said guide wheels, all in combination, and operating as and
for the purpose herein described and illustrated.
Secondly. In the manufacture of tubes for cycle construction and other
purposes, the formation and arrangement of rolls, the guide wheels, the mandre!
having a gauge or stop thereon, the adjustable back centre or support, the
adjustable screw, and screw pin in connection therewith, adjustably secured in slot

page_text: holes in the bed of the machine, all in combination with gear wheels, and pulley
wheels, and banding, and operating as and for the purpose substantially as herein.
described and illustrated.
Thirdly. In combination with suitable machinery, our improved arrangements.
for the manufacture of cycle tubes and other tubes as described.
