IMPROVEMENTS IN COILER CANS FOR SPINNING MACHINERY
Year: 1880

page_text: LETTERS PATENT to Gerard Wenzeslaus von Nawrocki, of the Firm of
J. Brandt and G. W. v. Nawrocki, of 124, Leipziger Strasse, Berlin, Germany,
Patent Agent, for an Invention of "IMPROVEMENTS IN COILER CANS FOR
SPINNING MACHINERY." A communication from abroad by August Naumann,
of St. Petersburg, Russia.
PROVISIONAL SPECIFICATION left by the said Gerard Wenzeslaus von
Nawrocki at the Office of the Commissioners of Patents on the 22nd March
1880.
GERARD WENZESLAUS VON NAWROCKI, of the Firm of J. Brandt and G. W. v.
Nawrocki, of 124, Leipziger Strasse, Berlin, Germany, Patent Agent. "LMPROVE-
MENTS IN COILER CANS FOR SPINNING MACHINERY." A communication from
abroad by August Naumann, of St. Petersburg, Russia.
This Invention has for its object to remedy certain defects common to the coiler
cans used for spinning mills, and hitherto made of tin plates. It consists in
constructing the coiler can of a pasteboard cylinder with a wooden bottom, and
having at the top an inside ring, and at the bottom an outside ring of hoop iron
for giving the necessary firmness to the can.
The manufacture of the pasteboard cylinder is extremely simple. Loose paste-
board, coated on one side with any suitable strong sticking substance, is wound
round a metal calender and subjected to the heavy pressure of a roller until its
substance is brought to the required thickness of the cylinder, when it is taken off,
dried, and coated with repeated coats of chrome glue. If desired the cylinder may
be covered with linen or jute for rendering it more durable. These coiler cans have
the following advantages over those mado of tin plates:-They are much lighter,
more durable, and cheaper, moreover they do not damage the spinning, as is the
case with even the best tinned coiler cans, which often rust and produce a rough
surface with loss of fluff and irregular working.

Nawrocki, of 124, Leipziger Strasse, Berlin, Germany, Patent Agents. IMPROVE-
MENTS IN COILER CANS FOR SPINNING MACHINERY." A communication from
abroad by August Naumann, of St. Petersburg, Russia.
This Invention has for its object to remedy certain defects common to the coiler
cans used for spinning mills, which cans have been hitherto made of tin plates.
- It. consists, as shown by Figs. 1 and 2 on the accompanying Drawing, in
constructing the coiler can of a pasteboard cylinder a with a wooden bottom b,
and having at the top an inside ring c, and at the bottom an outside ring d of
hoop iron for giving the necessary firmness to the can.
Loose
The manufacture of the pasteboard cylinder a is extremely simple.
pasteboard, coated on one end with any suitable strong sticking substance, is
wound round a metal calender and subjected to the heavy pressure of a roller until
its substance is brought to the required thickness of the cylinder, when it is takon
off, dried, and coated with repeated coats of chrome glue. If desired the cylinder a
may be covered with linen or jute for rendering it more durable.
These coiler cans have the following advantages over those made of tin plates:―
They are much lighter, more durable, and cheaper, moreover they do not damage
the spinning, as is the case with even the best tinned coiler cans, which often rust
and produce a rough surface with loss of fluff and irregular working.
Having now described the nature of the said Invention, and the manner in
which the same is or may be used or carried into effect, I would observe in
conclusion that what is novel and original, and therefore claimed as the Invention
secured to me by the hereinbefore in part recited Letters Patent is,―
In spinning machinery the construction and use of pasteboard coiler cans,
substantially as and for the purpose hereinbefore described and illustrated by the
accompanying Drawing.
In witness whereof, I, the said Gerard Wenzeslaus Nawrocki, have hereunto
set my hand and seal, this Tenth day of September, in the year of our
Lord One thousand eight hundred and eighty.
