UNITED STATES PATENT OFFICE,
WILLIAM KOEUL, OF HUNTSVILLE, TEXAS.
IMPROVEMENT IN COTTON-GINS.
Specification forming part of Letters Patent No. 164,44, dated June 22, 1875; application filed
March 13, 1875.To all whom it may concir:
Be it known that I, WILLIA3 KOEnIL, of
Huntsville; in the county of Walker and State
of Texas, have invented a new and valuable
Improvement in lovable Brushes for Cotton-
Gins; and I do hereby declare that the follow-
ing is a full, clear, and exact description of
the construction and operation of the same,
reference being had to the annexed drawings
making a part of this specification, and to
the letters and figures of reference marked
thereon.
Figure 1 of the drawing is a representation
of a sectional view of my device, and Fig. 2 is
a plan view of the same.
This invention has relation to improvements
in cotton-gin brushes.
The object of the invention is to devise a
means for moving the brushes nearer the
saws, when, from constant use, they have been
so shortened as to be incapable of performing
their function of stripping the said saws, and
to render them equally effective when thus ap-
proxinated as when first put into operation.
To this end, the nature of the invention
consists in movable journal bearings for the
brush-drum, which bearings are provided, as
to their under surfaces,with transverse grooves,
forming saw-teeth, adapted to be received into
correspondingly-shaped teeth in the gin-frame,
whereby the brush-drum is adapted to be
moved toward the saw-drum, bringing the
brushes of the former in contact with the teeth
of the latter.
In the annexed drawings, A designates a
beam of the cotton-gin fame; B, the journal-
bearing of the saw-drum, and C that of the
brush-drum, in connection with which I pro-
pose to illustrate my improvements. The up-
per surface of beam A is provided with a rack-
bar, a, the teeth of which present the appear-
ance of those of a saw; and this rack-bar may
be either a component part of the said beam
or a separate and distinct mechanism rigidly
secured thereto. In this latter ease I prefer
that it should be recessed into the beam, so
that the apexes of the teeth shall be in the
same horizontal plane with the upper surface
of the beam; and in either case it may be of
metal. The under side or surface of the jour-
nal-bearing C of the brush-cylinder has flanges
c, through which are cut slots d in the length
thereof, and the under side of these flanugesare corrugated or ridged, as shown, which
ridges, designated by the letter e in the
drawings, are of corresponding form with the
teeth of the rack-bar a, so that when the said
journal-bearing is put in position upon beam
A, the depressions of the one shall fit snugly
over the elevations of the other, shown in
Fig. 1. D represents bolts passing from be-
low upward through beam A into slots d of
the journal-bearing C, upon the upper screw-
threaded ends of which are applied nuts f.
Journal-bearing C is clamped in position on
its supporting-beam by settingup unutsf forci-
bly against flanges c.
When the brushes have been so worn by
the saws as to be no longer capable of perform-
ing their function of stripping the latter, I re-
move the nuts, and thrust the movable bear-
ing C one tooth nearer the saw-drum, there-
by replacing thein in contact with the saws,
and restoring their effectiveness in a degree
quite equal to that which they originally, pos-
sessed.
By this means the brushes are rendered
operative until they are completely worn out,
tihus securing a greater amount of service
therefrom, and postponing the time when
they will require to be renewed by the manu-
facturer.
In practice, I propose to make the teeth of
rack-bar a and those of the movable journal-
bearings C three-sixteenths (-%) of an inch
apart; but if I so elect I may increase or lessen
their interval.
I am aware that cotton-gin brushes have
heretofore been adjusted with regard to the
fixed saw-shaft, and I therefore lay no claim,
broadly, to such invention.
What I claim as new, and desire to secure
by Letters Patent, is-
The brush-drum, jonrnal-bearing C, adjusta-
ble in relation to the fixed saw-shaft bearing
B by means of the serrations a e, slotted
flanges c, bolts I), and nuts f as and for the
purpose specified.
In testimony that I claim the above I have
hereunto subscribed my name in the presence
of two witnesses.
WILLIAM KOEHIL.
