This invention comprises an elastic or spring plate and a bar provided with a
series of screws over such plate, in combination with a rotary cylinder and beater;
and with a curved plate or seed arrester, extending and provided with a bearing
shoulder, to rest against such spring plate.
Also the combination of a toothed chute, rotary cylinder, rotary and spiral
winged beater, toothed guard, seed arrester, and a spring plate with its series of
supporting screws and a supporting bar, and having mechanism for separating the
said beater and cylinder.
Also the combination of a rotary cylinder, rotary and spiral winged beater,
toothed guard, seed arrester and a spring plate with its series of supporting screws
and a supporting bar, and mechanism for operating the said beater and cylinder
Also the combination of a rotary cylinder, a spiral and corrugated winged and
rotary beater, a toothed guard and seed arrester and a spring plate with its series of
supporting screws and thin bars and mechanism for operating said beater and
cylinder.
The machine acts as follows:
On the chute being supplied with cotton having seeds in it, and the driving
shaft being put in revolution, so as to cause the cylinder and the rotary beater to
revolve the cotton will be drawn upward between the cylinder and the seed
arrester, and by such will be stripped from the seeds, while they will be stopped
by the seed arrester.
The beater revolving in the meantime will aid in separating the seeds from the
cotton, and will drive them downward, so as to cause them to be discharged between
the teeth of the chute.

page_text: As the cotton passes between the cylinder and the seed arrester, the latter will
give way and allow it to be advanced by the cylinder, from which it may be
removed by a doffer, or other suitable device.
The seed arrester by means of its elastic supporting plate, will be pressed down
upon the cotton and not only will be prevented from moving forward with the
cylinder, but be enabled to accomodate itself to the mass of cotton passing between
it and the cylinder. Any tendency of the cotton to pass upward over and upon
the upper surface of the seed arrester, will be checked by the beater while revolving,
which not only serves to prevent such passage of the cotton but to aid in separating
it from the seeds and to discharge them as herein before mentioned.
By means of the series of supporting screws the pressure of the elastic plate on
the seed arrester may be increased or diminished as circumstances may require
The guard serves to intercept any cotton that may be thrown upward by the
beater, and to cause such cotton to be carried by the beater over and down upon
the said arrester, and into or upon the mass that may be in the act of being drawn
forward between the cylinder and the seed arrester.

HERBERT JOHN HADDAN, of Kensington, Middlesex,
"IMPROVEMENTS
COTTON GINS," a communication to me from abroad by Daniel Simeon Chapin,.
of Massachusetts, United States of America
In the accompanying drawings Fig. 1 is a top view. Fig 2 a side elevation, and
Fig 3 a longitudinal section of a gin provided with this invention the nature of
which I have defined or attempted to define in the claim or claims hereinafter
presented. Fig. 4 is a top view, and Fig. 5 an end view of the concave plate or
seed arrester, to be explained. Fig. 6 is a top view, and Fig. 7 an end view of the
plate spring or elastic supporter of the seed arrester.
In such drawings A denotes the frame for supporting the main operative parts-
of the gin, there being within such frame, an inclined chute B, having a series of
teeth a, projecting from it, at its inner edge, and terminating near to the periphery
of a leather covered cylinder C. This cylinder arranged within the frame in
manner as represented, has its journals supported in suitable bearings, and fixed
to one of them a gear b, that engages with a pinion c carried by a driving shaft d.
The shaft d, supported in suitable boxes e, e, is provided with another gear f,
that engages with a pinion g fixed on the shaft or one of the journals of a rotary
beater D, which is arranged in rear of the cylinder and above its axis, such being
as represented.
This beater has one or more spiral wings h each of the said wings, being not
only arranged spirally on the shaft i, but having a corrugated or serpentine or
waved shaped outer edge, as represented, which is to be part of the circumference
of a cylinder whose radius, is equal to the distance of the said edge from the axis
of the beater shaft. This beater is to run close to the seed arrester and the
periphery of the cylinder C.
Extending over the beater in the manner as represented, is a guard E, consisting
of a series of curved wires or teeth k, projecting from a horizontal bar F, arranged
in the frame in manner as shown. In the said bar is a series of screws G, each of
which screws into and through the bar and against a plate spring or elastic plate H,
which at its front edge rests on the frame A, and against studs 1, 1, extending up
therefrom. At its lower edge or part, the plate H rests on the concave plate or
seed arrester I, which in turn rests. on the upper part of the periphery of the.
cylinder C. This seed arrester is constructed with or has a shoulder m, to rest
against the rear edge of the elastic plate H.
On the chute being supplied with cotton having seeds in it, and the driving
shaft d, being put in revolution, so as to cause the cylinder C, and the rotary
beater D to be revolved in directions as indicated by the arrows n and o, marked
on them in Fig. 3-the cotton will be drawn upward between the cylinder and the
seed arrester, and by such will be stripped from the seeds, while they will be
stopped by the seed arrester. The beater revolving in the meantime will aid in
separating the seeds from the cotton, and will drive them downward, so as to cause
them to be discharged between the teeth of the chute.
As the cotton passes between the cylinder and the seed arrester, the latter will
give way and allow it to be advanced by the cylinder, from which it may be
removed by a doffer, or other suitable device.
The seed arrester by means of its elastic supporting plate, will be pressed down
upon the cotton and not only will be prevented from moving forward with the

page_text: cylinder, but be enabled to accommodate itself to the mass of cotton passing
between it and the cylinder. Any tendency of the cotton to pass upward over
and upon the upper surface of the seed arrester, will be checked by the beater
while revolving which not only serves to prevent such passage of the cotton
but to aid in separating it from the seeds-and to discharge them as hereinbefore
mentioned.
A beater made with one or more straight wings, will not operate to the advantage
that one will having a spiral wing or wings, and especially when each spiral wing
of it is waved or serpentine transversely at its edge as represented, and such edge
constitutes part of the periphery of a cylinder, as explained-and therefore the
spiral wing beater, or one having each wing spiral and corrugated as represented,
constitutes in connection with the rotary cylinder and the seed arrester and its
elastic support plate-important features of the invention.
By means of the series of screws G, in the bar F, the pressure of the elastic
plate on the seed arrester may be increased or diminished, as circumstances may
require.
The guard E serves to intercept any cotton that may be thrown upward by the
beater, and to cause such cotton to be carried by the beater over and down upon
the said arrester-and into or upon the mass that may be in the act of being drawn
forward between the cylinder and the seed arrester.
In practice, a gin constructed as herein before described, has been found to operate
very successfully.
I claim:
1. The elastic or spring plate and the bar and its series of screws over such
plate, arranged as represented in the frame-in combination with the rotary
cylinder and beater and with the curved plate or seed arrester extending and
provided with the bearing shoulder, to rest against such spring plate-all being to
operate essentially as explained.
2. The combination of the toothed chute-rotary cylinder, rotary and spiral
winged beater, toothed guard, seed arrester, and the spring plate with its series of
supporting screws and the bar-all arranged and adapted and having mechanism
for operating the said beater and cylinder substantially as set forth.
3. The combination of the rotary cylinder, rotary and spiral winged beater,
toothed guard, seed arrester and the spring plate with its series of supporting
screws and the bar; all arranged and adapted and having mechanism for operating
the said beater and cylinder, substantially as represented.
4. The combination of the rotary cylinder, the spiral and corrugated winged and
rotary beater, the toothed guard, seed arrester and the spring plate with its series
of supporting screws and their bar, all arranged and adapted, and having mechanism
for operating said beater and cylinder, substantially as represented.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this 6th day of March A.D. 1884.
IT T HADDAN
