IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUB- STANCES
Year: 1878

page_text: LETTERS PATENT to Alexander Frerichs, of Hamer Hall, New Mills, Rochdale,
in the County of Lancaster, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUB-
STANCES."
Sealed the 12th July 1878, and dated the 26th January 1878.
PROVISIONAL SPECIFICATION left by the said Alexander Frerichs at the
Office of the Commissioners of Patents on the 26th January 1878.
ALEXANDER FRERICHS, of Hamer Hall, New Mills, Rochdale, in the County of
Lancaster. "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING COTTON
AND OTHER FIBROUS SUBSTANCES."
My Invention consists in certain improvements in parts of throstles and doublers,
the object of which is to enable them to do more work. The bolster that supports
the spindle is fixed in the rail in the usual way, and the top of it is carried above
the rail and up inside the bobbin, but not to the top of it, so that the bobbin at the
top touches the spindle. On the outside of the bolster is a loose tube (which may
be carried up to the top of the bolster or not, as required); the bottom end of the
bobbin goes on to this tube. In some cases I form a flange or projection on this
tube, and above this flange or projection is a plate or washer, on which the cloth
rests that carries the bobbin. This plate being above the flange or projection,
prevents the tube being lifted off the bolster by the bobbin.

ALEXANDER FRERICHS, of Hamer Hall, New Mills, Rochdale, in the County of
Lancaster. "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING COTTON
AND OTHER FIBROUS SUBSTANCES."
My Invention consists in certain improvements in parts of throstles and doublers,
the object of which is to enable them to do more work, and consists as follows:-
The bolster that supports the spindle is fixed in the rail in usual way, and the
top of it is carried above the rail and up inside the bobbin, but not to the top of it,
so that the bobbin at the top touches the spindle. On the outside of the bolster is
a loose tube (which may be carried up to the top of the bolster or not, as required);
the bottom end of the bobbin on to which the yarn or thread is wound goes on to
this tube, and is thus kept from touching the bolster.
And in order that my Invention may be fully understood and readily carried into
operation, I will now proceed to describe the accompanying Drawing.
Figure 1 illustrates how my Invention may be performed, and is shewn partly in
section.
a is the bolster, which is fastened in the rail b by the nut c.
This bolster passes
up inside the bobbin d, but not to the top of it, so that the bobbin touches the
spindle e at the top end. g is a loose tube without flange or projection, which turns.
round on the outside of the bolster a, and on to this tube the bottom end of the
bobbin passes, and is thus kept from rubbing on the outside of the bolster a.
The bobbin rests on the washer cloth in the usual way.
Figure 2 is an elevation of the loose tube g; and Figure 3, a plan of the
same.
Having now described my Invention, and shown how the same may be carried
into effect, I wish it to be understood that I do not claim as my Invention the
bolsters a or loose tubes with flanges or projections, as I find they have been used
before, but I claim as my Invention the loose tube g as shown and described.
In witness whereof, I, the said Alexander Frerichs, have hereunto set my
hand and seal, this Twenty-fourth day of July, in the year of our Lord
One thousand eight hundred and seventy-eight.
