PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Metal Tubes, Sleeves, and
the like.
I JOHN KEMP STARLEY of The Meteor Works Coventry in the County of
Warwick, Velocipede Manufacturer do hereby declare the nature of this invention
to be as follows:-
My invention relates to the method of preparing the edges of the flat plates or
strips used in the manufacture of metallic tubes, sleeves or the like (and particularly
such as are used in the construction of velocipedes or light road vehicles) previously
to such edges being turned up for the purpose of securing them together by brazing,
soldering, welding or other process.
After the plates or strips have been cut, rolled, stamped or otherwise formed of
the desired shape and thickness according to the nature of the work for which they
are required I further prepare them for brazing, soldering, welding or other process
as follows.
Along or around one longitudinal or external edge of the plate or strip I cut,
roll; stamp or form indents or teeth which may be dovetailed S shaped, scalloped
or of like suitable character and on the opposite edge of the said plate or strip I
form corresponding teeth or indents of a like character but so situated and in such
manner that the projections on one edge will take into the recesses or indents on
the opposite edge and vice versa so that the two edges may be locked or keyed
together when the same meet or nearly so on the plate or strip being turned up for
the purpose of brazing, soldering or the like and so forming the tube or other
device.
Where more than one diameter is required say to form a junction or socket joint
or to connect another tube or sleeve I may form the same in two parts to each of
which my method may be applied.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Metal Tubes, Sleeves, and
the like.
I JOHN KEMP STARLEY of The Meteor Works, Coventry in the County of
Warwick, Velocipede Manufacturer, 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 :-
My invention relates to the method of preparing the edges of the flat plates or
strips used in the manufacture of metallic tubes, sleeves and the like and particularly
to the manufacture of tubes, sleeves and like parts used in the construction of
velocipedes or light road vehicles.
After the plates or strips have been cut or formed of the desired length, width,
thickness, or general form according to the nature of the work for which they are
required and before such plates or strips have been turned up
i further prepare
them at their edges for soldering brazing or welding as follows or if such plates or
strips be rolled they may be prepared in first instance by or during such rolling
and in order to more fully explain my method of preparation I have attached to
this Specification a sheet of drawings to which I shall refer.

page_text: Along one longitudinal or external edge of the plate or strip I cut, stamp or form
indents or teeth either dovetailed as shown by Figures 1 and 2 or scalloped or
S shaped as shown by Figure 3 or of like suitable character and on the opposite
edge I cut, stamp or form corresponding teeth or indents in such a manner that
when the plate or strip (Figure 2) is turned up in the process of manufacturing the
tube or the like, the projecting portions or teeth on one edge will take into the
receding or indented parts of the opposite edge and vice versa so that the two edges
may be locked or
keyed together, as shown by Figures 1 and 3 daring the process
of brazing or welding and thus a much greater proportion of the metal will be
affected by the brazing, soldering or like operation than if a straight or similar
joint be made.
When tubes or sleeves of more than one diameter are required I may stamp or
form such of two or more parts as shown by Figures 4 and 5 so that by such
means the socket ends of a larger diameter may be formed or junctions of one tube
or part to another effected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In preparing blanks or strips for the manufacture of metallic tubes, sleeves or
the like, indenting, serrating or escalloping the edges thereof oppositely so as to
form a lock or key when such edges are brought together previous to the brazing,
soldering or welding, substantially as hereinbefore described and as illustrated by
the accompanying drawings.
