page_text: I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this invention, (a communication to me
from abroad by Abraham Gould Jennings of No. 313, Clinton Avenue, Brooklyn,
Kings County, New York, United States of America, Manufacturer) and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
The object of this invention is to separate the fibres from the seed of cotton in
such a manner that the fibres will not be broken and torn, as is ordinarily the case
in ginning cotton, but will be left at their full length thereby increasing the valuable
qualities of the cotton as ginned.
The Invention consists in providing means for forcing the cotton by air pressure
from the carrier to the receiving or ginning roller.
Reference is to be had to the accompanying drawing forming part of this specifi-
cation, in which figure 1 is a sectional view of the improved cotton gin, taken on
the line cc figure 2; figure 2, is an end view of the same; figure 3 is a sectional
view of the cotton carrier, blower grating, and roller; and figure 4 is a sectional
view, shewing a modification of the grating. Similar letters of reference indicate liko
parts in all the figures.
A in the accompanying drawing, represents the frame of the improved cotton gin.
B is the cotton carrier, suitably mounted on rollers D D. The carrier B is perforated,
being preferably made of wire cloth, and has secured to it, teeth, cards or pins b by
which to hold the cotton. Journaled in the frame A, are the ginning rollers E which
carry the teeth or pins e. Between the carrier B and the rollers E, is a grating d
of bars, the openings in the grating being sufficiently narrow to prevent cotton seed
passing through. F is an air blower, whose discharge spout f terminates on the
inner side of the carrier B opposite a roller E. The blower F receives the air from
any suitably arranged mechanism. G is a hopper or incline upon which the cotton to
be ginned may be placed. H are doffers suitably arranged for removing the ginned
cotton from the rollers E.
In the modification shewn in figure 4, the grating d opposite each roller E is
horizontal, instead of vertical.

page_text: This cotton gin operates as follows;-The cotton to be ginned is fed to the carrier B
in any suitable manner, but preferably from the incline G. It is then carried along
on said carrier till it is opposite the air spout where it is blown against and partly
through the grating d. This grating does not allow the seed to pass. But the fibres
projected between the grate bars d are caught by the teeth e on the roller E and
drawn outward from between the grating, leaving the seed free, which then drop
down and are caught in any suitable receiver. The cotton fibres are removed from the
roller E by means of doffer H, in the usual manner.
The gin may be provided with any desired number of rollers E and spouts f, two
such spouts and rollers being shewn in the drawing.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1. A cotton gin, provided with an air spout for forcing the cotton from the carrier
into reach of a receiving roller, as specified.
2. In a cotton gin, the grating d and blower F in combination with the carrier B
and means substantially as described for drawing the fibres of the cotton through the
grating, as set forth.
3. In a cotton gin, the blower F combined with the grating d, carrier B, and
roller E, substantially as described.
4. In a cotton gin, the combination of a porous carrier with an air spout on one
side and a grating on the other side, for forcing the fibre into or through said grating,
as set forth.
