Year: 1878

page_text: LETTERS PATENT to Edmund Schmidt, of the Firm of G. W. Schmidt, in
Chemnitz, in the German Empire, for the Invention of "AN IMPROVED
MANUFACTURE OF DRIVING BELTS OF COTTON FIBRE."
:
PROVISIONAL SPECIFICATION left by the said Edmund Schmidt at the
Office of the Commissioners of Patents on the 30th July 1878.
EDMUND SCHMIDT, of the Firm G. W. Schmidt, in Chemnitz, in the German'
Empire. "AN IMPROVED MANUFACTURE OF DRIVING BELTS OF COTTON FIBRE."
According to my present Invention I manufacture driving belts of cotton fibre by
employing for that purpose either twisted, braided, or plaited threads or yarns, which
are woven into a twill fabric of the width of the required belt.
For making the twisted threads or yarns, single or double yarns or threads are
formed into twisted strands, of which two or more are again spun into a strong
twine. .
For making the braided or plaited threads or yarns, single yarns or threads or
doubled yarns are braided or plaited into threads of any desired strength. In all
cases, whether the belts be made entirely of twisted yains or threads, or cutirely of
braided or plaited yarns or threads, or whether the warp be made of the one
description of thread and the shoot of the other description, the said threads are
woven into a twill of that description in which the warp threads appear on the
surface on both sides, while the shoot is as much covered in as possible.
The twill should be of such a nature as to contain the greatest possible number
of warp and shoot threads in a given surface.
With belts that are made entirely of twisted threads, or of which the warp alone
is made of such threads, the one half of the warp must be spun right-handed, and
the other half left-handed, in order that there may be no tendency in the belt to
twist.

"
According to the present Invention we manufacture driving belts of cotton fibre,
by employing for that purpose either twisted, braided, or plaited threads or yarns,
which are woven into a twill fabric of the width of the required belt.
For making the twisted threads or yarns, single or doubled yarns or threads are
formed into twisted strands, of which two or more are again spun into a strong

For making the braided or plaited threads or yarns, single yarns or threads or
double yarns are braided or plaited into threads of any desired strength. In all
cases, whether the belts be made entirely of twisted yarns or threads, or entirely of
braided or plaited yarns or threads, or whether the warp be made of the one
description of thread, and the shoot of the other description, the said threads are
woven into a twill of that description, in which the warp threads appear on the
surface on both sides, while the shoot is as much covered in as possible.
The twill should be of such a nature as to contain the greatest possible number
of warp and shoot threads in a given surface.
With belts that are made entirely of twisted threads, or of which the warp alone
is made of such threads, the one half of the warp must be spun right-handed, and
the other half left-handed, in order that there may be no tendency in the belt to twist ;
the above-described driving belts may either be used in their natural state, or they
may be previously heated or impregnated with any suitable substance.
Having thus described the nature of the said Invention, and in what manner the
same is to be performed, we claim, the manufacture of driving belts of cotton,
twisted, braided, or plaited yarns, woven into twill, substantially as herciu
described.
In witness whereof, we, the said Clara Selma Schmidt and Johannes Heinrich
Reitz, have hereunto set our hands and seals, this Twenty-third day of
January, in the year of our Lord One thousand eight hundred and seventy-
