Improvements in Cotton-gins.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
:-
This invention relates to that class of cotton-gins known as "roller-gins," in
which a revolving beater, sometimes called a clearer or stripper, is used, and it
consists in the combination with the other essential parts of the gin of the beater
constructed as hereinafter described and illustrated in the accompanying drawings, in
which
Figure 1 is a view in perspective of my improved beater.
Figure 2 is a cross section of the same.
Figure 3 is a longitudinal section of one end of the same.
Figure 4 is a central vertical section of a portion of a cotton-gin with my beater in
position.
Similar letters of reference indicate like parts in the several figures of the
drawings.
A represents the frame, B the table, the drawing-roller, D the upper doffer,
E the lower doffer, and I the pressure-bar, all constructed substantially as heretofore.
JJ' are fingers and a finger bar constructed as described in United States Letters
Patent numbered 418,908 dated January 7th 1890.
K is the roll constituting the body of the beater, provided at its opposite ends
with the integral shafts K¹ by means of which it is rotated.
LL are four, more or less, parallel straight radial wings made preferably of
hardened steel of substantially the dove-tailed shape shown, secured in the body of
the beater by being slid into corresponding longitudinal dove-tailed grooves. The
wings are prevented from longitudinal movement by the collars P which are pinned
to the shaft of the beater as shown next the opposite ends of said wings. As will
readily be seen, these wings are removable, and interchangeable, so that when one
wears out or breaks it can be quickly replaced by another.
It has also the advantage over a spiral or corrugated beater that the feed is
uniform for the length of the roller, while a spiral beater has a tendency to convey
the seed cotton to one end of the roller; moreover the direct motion had by the
straight beater-wings tends to prevent kinking, curling, or twisting of the fibre.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
In a roller cotton-gin, the combination with the drawing-roller, of the winged beater
or stripper described consisting essentially of the main portion or roll K and the
straight longitudinal wings L held removably in longitudinal grooves in the roll, and
prevented from longitudinal movement by the collars P substantially as described.
Dated this 23rd day of September 1890.
