sides and then passes between the feed roll H and evener plates K, K,
when by the combined operation of the parts connected therewith the
speed of the feed rolls E, F, is such as to deliver to the beater a regular
and even quantity of cotton. It has been found by experience when
the cotton is fed directly to the beater from the evener plates that so
great a weight upon the feed roll is necessary to keep the cotton from
being drawn in faster than is desired as to destroy the sensitiveness of
the evener, and to render it useless for the purpose intended.
By the use of this Invention only so much weight upon the feed roll
is necessary as to pass the cotton over the evener plates, the feed rolls
through which the cotton then passes performing the work of presenting
the same to the beater and holding it while operated upon by said
beater.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN MACHINERY FOR OPENING, CLEANING, SCUTCHING, AND LAPPING COTTON AND,

page_text: OTHER FIBROUS MATERIALS," and have petitioned Her Majesty to grant
unto me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made solemn Declaration that it has
been communicated to me from abroad by William E. Whitehead, of
Miles Platting, in the County of Lancaster, now residing in Massa-
chusetts, United States of America, and Abel T. Atherton, of Lowell,
Massachusetts, United States of America, Machine Makers.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawings forming
a part of the Specification:-
This Invention consists first in the employment of a cylinder in an
opener or similar machine, constructed either of rings or equivalent
contrivances, having attached to their periphery one or more angle
plates, and one or more toothed plates, or with the said periphery
covered exclusively with angle plates, these plates being constructed
in such a manner as to impart to the cylinder great strength and
effectiveness in opening and cleaning cotton.
11+
The said Invention further consists in the application of motion to
the longitudinal grid bars, by which a greater means is presented for
the escape of the dirt and other refuse removed from the cotton by the
action of the machine.
The said Invention further consists in the employment of adjustable
bushings, wherein the shafts revolve in combination with the plate
boxes which support the same.
The said Invention further consists in the employment of an adjust-
able swinging stripping roll in connection with another stripping roll,
by means of which all danger of breaking the driving apparatus is
avoided.
The said Invention further consists in the manner of attaching the
sheet iron, covering to the cylinder.
The said Invention further consists in the process of evening the
cotton before it passes through the feed rolls or other arrangement
intended to hold the cotton while being acted upon by the beater; the
object of this part of the said Invention being to relieve the feed roll

page_text: Figure 8 is a section on the line "A, B," Figure 1. .

page_text: His a cylinder composed wholly of a series of flat angle plates, or
with one or more toothed plates in combination with one or more flat
angle plates attached to two or more rings or equivalent contrivances.
These plates are strongly attached to the rings by occupying recesses
upon the periphery of said rings; I, I, I, are a series of movable 5
longitudinal grid bars, supported at each end, and moved by means
of the rack operating by the cam or other mechanism connected
therewith; K is one of two links, each connected at one end to the
shaft of the cylinder X, and at the other end to the shaft of the
adjustable swinging stripping roll M; L is a slot in which the. 1
adjustable swinging stripping roll moves; M³ is another stripping roll,
which operates in connection with M%; N is a plain angle plate,
constructed with strong braces, and shewing upon its edges the slots
for the reception of the sheet-iron plates for covering the open spaces
in the cylinder H; O is a toothed angle plate; R is a spring operating 1
in connection with the movable bar rack G to return the bars to their
places or proper position after they have been moved by the cam P;
S, S, are sheet-iron plates, which cover the space on the outside of the
cylinder between the angle plates, and which are inserted in the slots
shewn in the edges of the angle plates; T is a bushing resting upon
the rib V in the plate box U, and held in its place by a set screw W,
entering by its point into a countersunk hole in the top of the bushing.
The rib is made by boring and counterboring the plate box U.
Cylinders have been made before, having flat blades attached to their
surfaces, but owing to the impossibility of firmly securing the same
they have been abandoned. By having the grid bars movable 'dirt
or other refuse matter lodging upon the bars is shaken through the
spaces between the same, so that all danger in consequence of the dirt
collecting and filling up the said spaces and passing with the cotton
to the lap is avoided. The adjustable bushing adapts itself to any
uneveness of the floor surface, and is easily removed when worn
out.
any
When the stripping rolls are both stationary, in case a large body
of cotton passes between the same, the gear wheels driving the rolls
are broken, while during the use of one stripping roll the upper one,
by being hung from the top cage shaft by means of the links, adjusts
itself to any uneveness of the lap, and all danger of breaking the gear

page_text: It has been found by experience that when the sheet-iron covering
attached to the cylinder is fastened to the rings by means of screws:
the drilling and tapping of the rings necessary to admit the said screws
renders the rings weak and more liable to break, while the edges of the.
sheet iron are liable to become raised from the rings and by coming in.
contact with the cotton are in consequence torn from the cylinder,
often causing disastrous results.

page_text: speed of the feed rolls E, F, is such as to deliver to the beater a regular
and even quantity of cotton. It has been found by experience when
the cotton is fed directly to the beater from the evener plates that so
great a weight upon the feed roll is necessary to keep the cotton from
being drawn in faster than is desired, as to destroy the sensitiveness of
the evener, and to render it useless for the purpose intended.
By the use of this Invention only so much weight upon the feed roll
is necessary as to pass the cotton over the evener plates, the feed rolls
through which the cotton then passes performing the work of presenting
the same to the beater, and holding it while operated upon by said
beater.
י
By the use of one grooved and fluted feed roll in combination with
one fluted feed roll the cotton passing between the same is held more
firmly and with considerably less weight than when either two plain
fluted rolls or one plain fluted roll and stationary plate are used, thus
saving a great amount of friction and diminishing the wear upon the
bearings of the feed rolls and amount of power required to operate the
machine.
Apron sides as heretofore constructed have been made of several
parts, the horns or projections as here represented being fastened to
the base of the side by means of screws. It is very difficult as well as
expensive to fit these parts together, while the slightest roughness in
the parts with which the cotton in passing to the evener comes in
contact produces a tearing of the lap. By the use of this Invention
these defects are entirely removed, as there being but one piece to the
entire apron side no roughness or obstacle is presented to interfere with
the free passage of the cotton. Apron sides have been constructed of
one piece, having two horns or projections upon cach for each lap in
use; but as a lap is frequently of great weight, and has to be raised by
the hands to a considerable height when being put upon the apron, a
the height of the extra horn or projection on which the lap has to be
raised produces an objection and inconvenience to its use, which is
entirely removed by this Invention.
Figure 16 is a general section of a machine embodying another part
of this Invention.

page_text: Figure 19 is a section through a portion of a cage cylinder and end
of frame, showing the air chamber; and Figure 20, a section shewing
whippers attached to off-set arms, herein-after described.
A is the frame of the machine; B is the opening cylinder, containing
one or more plain reels or spiders in combination with one or more off-
set reels or spiders, or composed entirely of either plain or offset reels or
spiders; C, C, are the feed rolls; D, D, are two cage cylinders, composed
of two or more rings covered with wire cloth or perforated metal; E is
a draft fan; F is an opening at the rear end of the machine for the
delivery of the cotton; G is an air chamber through which the current
of air produced by the action of the opening cylinder and the dust
from the cotton escape; H is a drop door, forming in connection with
the sides N, the "air cut off," and sand chamber; I, I, are the whippers
swinging on the rods K; L is a trunk through which the cotton passes
to the cage cylinders; M, M, are openings at the ends of the cage
cylinders to permit the escape of the air and dust into the air
chamber G.
The advantage to be gained by the use of a cylinder composed of
reels or spiders and whippers is that when a hard portion of cotton
comes through the feed rolls instead of "cutting it off" in the same
manner as a beater, the whipper rebounds after simply giving a blow
upon the cotton, which softens it, without injury to the staple, and the
following whipper loosens it from the feed rolls.
It is necessary in order to collect the cotton upon the cage cylinders
and make it leave the same in the form of a sheet or lap to have a
device in one or both wire cage cylinders called a "cut off," to prevent:
the drawing in of any air into the cage cylinders from the side nearest
to the beater, causing the cotton to adhere to the surface of the cage
cylinders, wind around the same, and produce a breakage of said
cylinders. This "cut off" of the air has heretofore been produced by
means of a semicircular or other form of sheet metal pan or pans, hung
in the cage cylinders; but there are many objections to this form of
cut off which are remedied by this Invention.
Having thus fully described the said Invention, as communicated to
me by my foreign correspondents, and the manner of performing the
same, I wish it understood that I claim,
