Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN THE PREPARATION OF WOOL AND
SIMILAR FIBRES FOR SPINNING, AND IN APPARATUS THEREFOR. -A com-
munication from abroad by Frederick Thomas Chase and. John
Henry Platt, both of Dudley, Massachusetts, United States of
America.
COMPLETE SPECIFICATION filed by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 1st April 1872, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.

use of steam in the stripper or by any other efficient means. The teeth
have only sufficient bend or pitch to carry the fibres after they are
delivered to them, and the strippers have a slower speed or motion than
is commonly used, their motion being only sufficient to comb and take
the wool from the workers. The evener-bar serves also to prevent the
stock from being taken by the strippers from the workers in patches or
a more or less uneven sheet, as it happens to be on the worker, without
straightening its fibres as it is taken by the strippers on the "cards
now in common use. The heat applied in this way to the stock through
the heated teeth of the first opening roll and strippers, or through the
teeth of all the rolls which take the stock from a properly arranged
holding mechanism like that composed of the feed roll and its shell, or
the combination of the worker with the evener-bar or surface, softens
the wool and relaxes and straightens the natural curl of the fibre,
enabling the teeth to comb and lay the fibres straight and parallel with
each other before the ends pass the "hold" or retention of the holding
mechanism.

applied thereto and the parts connected with the same, some portions of
the card not necessary to its explanation being omitted for the sake of
clearness.
Figure 2 shews the arrangement of the evener-bar with the worker
and its stripper on a larger scale, the broken lines showing the path or
track usually followed by the wool when it is taken by the stripper.
without the use of the bar.
A is the frame supporting (in the usual manner) the main cylinder B,
tumbler C, workers D, and strippers E; F. is the feed roll, which is
preferably small; G is its shell, placed below it somewhat in the manner
formerly used, but carried well up between the feed roll F and tumbler C
to make a hold as near as possible to the surface of the tumbler. Between'
the workers and strippers is placed the evener-bar H (a cross section of
which is shown at Z detached and drawn to a still larger scale)
extending across or the whole length of the workers. It is attached
to a standard I at each end, these standards being adjustable on the
supporters L, which are made with a hole at one end to slip on the shaft

In witness whereof, I, the said William Robert Lake, have
hereunto set my hand and seal, this First day of April, in the
