Improvements in Cotton-gins.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to that class of cotton-gins known as roller gins, and consists
in the application thereto of a "whipper" the use and construction of which are
hereinafter described with reference to the accompanying drawing in which
Figure 1 is a central vertical section of the operative parts of a roller cotton-gin
embodying the present invention.
Figure 2 is a side elevation in detail of a portion of the gin.
Figure 3 is a perspective view showing portions of the drawing roller and the
whipper "in position.
Similar letters of reference indicate corresponding parts in the several views.
A represents the frame, B is the table from which the seed cotton is fed into the
machine, C is the drawing roller, D is the beater or stripper driven by the wheel D',
E is the upper doffer for throwing back the unginned cotton, F is the lower doffer for
taking down the ginned cotton to the board H, and I is the pressure bar adjusted by
the screw mechanism J, none of the said parts being new in this invention, and the
operation of them being well known in the art to which this device appertains.
Ji Ji are fingers and a finger-bar constructed as described in British Letters Patent
numbered 293 and dated January 7, 1890.
On the shaft C' of the drawing roller C is fixed a crank K to which is pivotally
secured a rod or pitman L whose opposite end is pivotally secured to the crank N
whose hub N' is rigidly secured on the oscillating shaft O having bearings in the
journal box O. From this shaft O extends a series of rods P preferably metallic, the
whole constituting what I term a whipper.
R is a horizontal bar preferably of angle shape as shown, bolted to the table B.
Bars or wires S extend from the bar R to a similar bar R¹ parallel with the bar R
and lying next and on the fingers. J', the whole forming a grate. The rods P lie, as
shown in Figure 3, between the stationary bars or wires S. It will readily be seen
that the rotation of the roller shaft C³ causes the shaft or wipper frame O to oscillate
and the rods P to swing backward and forward rapidly between the bars S of the
grate. As the cotton is dropped onto the grate, therefore, the whipper striking it
bats the seeds out that have already been stripped of their lint. In other words it
removes the seeds that have been stripped of their lint, having been ginned and
thrown back by the beater.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent i declare that what I claim is :-
First. In a roller cotton-gin the combination of the oscillating shaft O and rods P
constituting the whipper, and frame, as R R¹, and bars S constituting the grate,
constructed to onerate anhstantially as cat forth

page_text: Second. In combination, the roller C and roller-shaft C¹, crank K, pitman L,
orank N, oscillating shaft O provided with the rods P and stationary frame R R¹ and
bars S, all constructed and arranged substantially as described.
Dated this 2nd day of September 1890.
