IMPROVEMENT IN CQTTON-GINS.

Specification forming part of Letters Patent No. 8,803, dated March 16, 1852.

T0 all whom it may concern.- 7

Be it known that I, THOMAS J. LAWs,of \Vashington, in the county of Hempstead and State of Arkansas, have invented a new and I combination of an additional brush-wheel, D,

with the saws B and the strippingbrnsh O of the ordinarily-constructed cottongin in such a manner as to cause the said additional brushwheel to remove the motes from the cotton while it is upon the teeth of the saws by acting against the front sides of the said sawtecth just before the cotton is stripped therefrom,

My improvement is applicable to all kinds of saw-gins, and therefore a particular representation and description of these well-known machines is not deemed necessary.

The accompanying drawing is a vertical section through a cotton-gin, showing its opcrating parts and their positions in a suitable supporting-frame.

A is the breast or roller box, in which the cotton is placed to be ginned and cleaned; B, one of the saws; I,'one of the ribs, and O the ordinary brush for stripping the cotton from the saws. Above the brush 0 a'mote-box, G, is formed by the partitions J K; and above the partition J is located the additional cleaning-brush wheel D in such a position as to The shaft of the brush -wheel D is banded or otherwise connected to the saw-shaft in such a manner as to cause the shaft of said brush-wheel to rotate in the same direction as the saw-shaft, which causes the brush to act against the front sides of the teeth of the series of ginning saws, and consequently enables it to act upon and remove the motes from the cotton as it is drawn through the ribs by the saw-teeth with out removing the cotton, which is carried forward upon the saw-teeth and stripped therefrom by the brush-wheel B' in the usual manner. The motes removed from the cotton by the brush-wheel D are discharged into the rhote-chamber G. I

In order to render the brush-wheel D efficient for extracting the motes and removing them to the mote-boX G, I apply to its periphery a series of radial projections or Wings, a v a, in which the radiating brush-bristles are secured, which wings produce, when rotated, a strong current of air in the direction of the motion of the brush. By. this arrangement the motes are not'only more readily extracted from the cotton, but are entirely removed into the mote-box G, thereby obviating the great defect of the common cylindrical mote-brush,

which does not throw off the motes separated from the cotton, and consequently soon clogs up and becomes useless.

I do not claim the use of a mote-brush, D,

in combination with gin-saws and the ordinary stripping-brush, as I am aware that a cylindrical mote-brush revolving in the same direction with mine has been used before; but

What I do claim as new, and desire to securpby Letters Patent, is-

Making the mote-brush(revolving in the direction described) with wings, so as to act by a current of air as well as by contact with the cotton.on the teeth of the saws, substantially as herein set forth, in combination with the saws and grate.

The above specification of my improvement in cotton-gins signed this 24th day of May, 1851.
