Cotton or other Fibrous Material.
I WILLIAM SEWARD ARCHER of 129 East 76th Street, New York, United States
of America, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to that class of machine described in the Specification of
former Letters Patent dated 23rd June 1885, No. 7650, and is designed to provide
various improvements the nature of which is hereinafter set forth.
According to my present improvements I furnish the platform or grate over which
the cotton or other stock passes in its passage from the picker to the cylinders, with
teeth similar to those in the toothed boards and inclined in the same direction, thus
ensuring a further separating and cleaning action at this point.
I also arrange the part comprising the horizontal ledge and trough below the feed
roller (viz. the part which I term the shell feed) in such manner that it can be
adjusted nearer to or farther from the picker roller in order that adjustment may be
readily made to suit the special kind of stock upon which the machine may be required
to operate.
Another feature of iny present invention consists in providing adjustable stops at
the rear end of each of the toothed boards situated beneath the picker roller, such stops
being capable of adjustment in a vertical direction according to the kind of stock
being treated.
A further improvement consists in making the picker-roller entirely of metal
instead of partly of metal and partly of wood. I drill or otherwise make the required
number of holes in the roller completely through the same and the teeth are inserted
therein and bolted or otherwise secured on the inner surface of the roller.
In some cases I may make the toothed boards beneath the picker roller in the form
of a grate or grill in order that the dirt and other impurities from the stock will have
a free and unimpeded exit.
My machine is applicable for the opening and cleaning of all kinds of cotton as well
as cotton waste and may take the place of a breaker card, making a most perfect
cotton lap.
Machines made according to my inventions effectually clean the stock but do not
injure the staple.

1, WILLIAM SEWARD ARCHER of 129 East 76th Street New York, United States
of America, Manufacturer do hereby declare the nature of the said invention and in what
manner the same is to be performed to be particularly described and ascertained in and
by the following statement :-
My Invention relates to that class of machine described in the Specification of
former Letters Patent dated 23rd June 1885, No. 7650, and is designed to provide
various improvements the nature of which is hereinafter set forth.
In the accompanying drawing I have shown how my said Invention can be
conveniently and advantageously carried into practice.
Figure 1 is a longitudinal vertical central section of part of a separating machine
showing my improvements applied thereto.
Figure 2 is a portion of Figure 1. drawn to an enlarged scale.
Figure 3 is a plan also drawn to an enlarged scale of the platform or grate herein-
after described the teeth being removed.
Like letters indicate corresponding parts throughout the drawing.
A is the picker roller, B are the cylinders, C is the feed apron, D are the feed
rollers.
a is the platform or grate over which the cotton or other stock passes in its passage
from the picker roller A to the cylinder or cylinders B. The said platform or grate a
is furnished with teeth b similar to the teeth c in the toothed boards c¹ situated
beneath the picker roller A and inclined in the same direction that is to say, in the
direction in which the stock or material travels, thus ensuring a further separating
and cleaning action of the stock or material at this point.
The parts comprising the horizontal ledge d and trough e below the feed roller D
are moreover provided with an extension e arranged to slide in grooves e² in a
bracket e or with other suitable means of adjustment so that the said trough e can
be adjusted nearer to or farther from the picker roller A. By this arrangement adjust-
ment may be readily made to suit the special kind of stock or material upon which the
machine may be required to operate.
Another important feature of my present invention consists in providing the said
toothed boards e with adjustable stops f. The adjustable stops are preferably placed
at the front and rear end of each of the toothed boards c'. The said adjustable stops
are capable of suitable adjustment in a vertical direction according to the kind of
stock or material being treated.
The platform or grate a is moreover in some instances also provided with adjustable
stops f.
In a slight modification I construct the picker-roller entirely of metal instead of
partly of metal and partly of wood. I drill or otherwise make the required number
of holes in the said roller completely through the same and insert the teeth therein
and bolt or otherwise secure the said teeth on the inner surface of the said roller.

page_text: In some cases moreover I may make the toothed boards beneath the picker roller
in the form of a grate or grill, the teeth of which are preferably inclined in the
direction in which the stock or material travels. The dirt and other impurities from
the stock will thus have a free and unimpeded exit.
I sometimes moreover place the adjustable stops hereinbefore described at the rear
end only of the toothed board, or of the platform, or grate, or I place the said
adjustable stops only at the front of the said toothed board or platform or grate. By
employing these adjustable stops any chance of back currents of air or refuse re-
entering the machine is obviated.
My machine is applicable for the opening and cleaning of all kinds of cotton, as
well as cotton waste and may take the place of a breaker card, making a most perfect
cotton lap.
Machines made according to my invention effectually clean the stock but do not
injure the staple.
Although I have herein before more particularly described my said invention as
applied to an opening or separating machine having a trough or shell feed it is obvious
that I can apply my improvements to a machine having feed rollers or pedals, or
any other suitable description of feed motion.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is,
First. In an opening or separating machine or the like, having an adjustable
trough, or shell feed, or other suitable feed motion, the employment of toothed
boards and a toothed platform, or grate, having adjustable stops, at the rear, or front
of the same, the teeth pointing in the direction in which the stock or material travels,
substantially as and for the purposes set forth.
Second. The toothed boards having adjustable stops, and teeth pointing in the
direction in which the stock or material travels, substantially as and for the purpose
set forth.
Third. The platform or grate provided with teeth pointing in the direction in which
the stock or material travels and with or without adjustable stops, all substantially as,
and for the purposes, set forth.
Fourth. The improved apparatus substantially as described with reference to the
accompanying drawing.
