IMPROVED COTTON OUST. 
EMERYS' PATENT. 
Plate V, No. 2. 
§ A. The Cotton Gin is one of the most important among modern inventions and any 
improvements in it, or its operations, are, as they should be, eagerly sought for by the cot- 
ton producer. The enormous amount of cotton, and its great value, which is annually made 
in this country, causes even the smaller improvement in its manipulation to command a ready 
adoption; and the numerous inventions 
and patents granted therefor since the in- 
troduction of Whitney's Saw Cotton Gin, 
go far to attest the great necessities 
and inducements for improvements. It 
is believed by the proprietors, who are 
familiar with previous efforts and pat- 
ents, that their own improvements are 
among the most valuable since Whit- 
ley's time, and that they are chiefly in 
a different direction from that of nearly 
all other inventors, and which has been 
heretofore overlooked. 
§ b. One of the best points in the im- 
provement is its adaptability to all saw 
gins now in use, as well as those being 
manufactured by the proprietors, while 
it is both simply and cheaply applied. 
§ c. The improvement consists 
-fEBGIISON-' 
chiefly of a cylindrical shaft of wood or other light material, so suspended within the hop- 
per, upon its journals at both ends, as to occupy the hollow center within the cotton roll, which 
is produced by the centrifugal force of the revolving mass within the hopper. 
This shaft is thickly studded throughout its surface with radially projecting pointed pins 
which become imbedded in the cotton, causing the shaft to revolve in unison with the roll by 
the force and motion which the cotton roll receives from the action of the saws upon it. 
§ d. Its purposes and objects are to produce a uniform motion of the roll throughout its 
whole length and circumference, and to support the seed cotton and prevent that portion 
which is presented to the action of the saws from being compressed upon the saws by the 
weight of the cotton roll ; also to avoid the consequent cutting and napping of the lint 
which would be caused thereby. 
Its use produces a constant revolution of the roll positively relative to that of the saws, and 
preserves its cylindrical form, irrespective of the different and varying velocities of the saws, 
or the centrifugal force of the revolving mass in the hopper. 
§ e. This shaft, with its pins, pre- 
vents all choking, clogging, bridging 
and breaking of the cotton roll from 
careless feeding or matted condition of 
the seed cotton, as the positive and 
forcible motion produced by the action 
of the saws upon that portion of the 
seed cotton roll lying between the saws 
and the shaft and communicated 
through it and its pins to the whole 
roll, is sufficient to overcome all such 
irregularities, and admits of the gin 
being worked up to the maximum pow- 
er applied, be it more or less, without 
danoer of stopping the operation of the 
oin or injuring the qualify of the lint. 
It also enables the gin to be worked 
with almost any power, and at any ve- 
| locity, and at the same time produces a 
J uniform quality of lint; and increases 
H the capacity for work in like propor- 
tion. 
The proprietors also manufacture 
their attachment for the gin, which en- 
ables the whole to be operated upon the 
field, if desired, and without any lint 
room or gin house being required, also 
delivering it at one and the same operation in 
Plate V, No. 2. 
for cleansing the lint from all dust and st 
fit condition for baling and the market.
