PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Fluted Rollers for
Spinning Machines.
I CHARLES MARTINOT of the Town of Bitschwiller-Thann, Upper Alsatia, Germany,
Engineer, do hereby declare the nature of my said invention to be as follows :-
:-
My invention relates to improvements in the manufacture of fluted rollers for
spinning machines, by rolling or drawing metal bars.
Metallic fluted or milled rollers are employed in roving machines for cotton, silk,
flax or other textile matter for transporting the material to be slubbed or roved.
These rollers have hitherto been milled or fluted in planing or milling machines, by
means of cutters, files, milling wheels etc., after having been previously turned and
prepared for the purpose. This is a very difficult and expensive operation, but all
inconvenience and excessive expense is avoided by employing metallic or other
fluted drawing rollers or draw plates.
on the roller
The gorges, journals and other necessary parts are turned into or
after it has been drawn or fluted. The grooving or fluting may also be produced by
passing the metallic bars through suitable drawing plates.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Fluted Rollers for
Spinning Machines.
I, CHARLES MARTINOT, of the Town of Bitschwiller-Thann, Upper Alsatia,
Germany, Engineer, do hereby declare the nature of my said 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 improvements in the manufacture of fluted rollers for
spinning machines, by rolling or drawing metal bars. Metallic fluted or milled rollers
are employed in roving machines for cotton, silk, flax or other textile matter for
transporting the material to be slubbed or roven.
These rollers have hitherto been milled or fluted in planing or milling machines,
by means of cutters, files, milling wheels etc., after having been previously turned and
prepared for the purpose. This is a very difficult and expensive operation but all
inconvenience and excessive expense is avoided by employing metallic or other fluted
drawing rollers or draw plates.
The gorges, journals, and other necessary parts are turned into or on the roller after
it has been drawn and fluted. The fluting or grooving can also be produced by
passing the metallic bars through suitable drawing plates.
In the accompanying drawing, Figures 1, 1 represent a roller not yet fluted in
the ordinary manner.
Figures 2, 2 represent the same roller fluted in a machine for planing, counter-
sinking or milling the grooves or flutes
Figures 3, 3ª represent a bar or roller fluted in its entire length.
Figures 4, 4 represent a roller of like form to that shown in Figures 2, 2*, but
made from the bar or roller as represented in Figures 3, 30, without having passed
through a planing, countersinking or milling machine.

page_text: 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 :-
t
The manufacture of hardened or unhardened fluted rollers for spinning machines
and machines for treating textile matter from bars or shafts drawn with grooves
or fluting of any desired diameter and form of groove or flute and any required
length or mode of capacity, substantially as specified and shown.
