IMPROVEMENT IN C OTTONGINS.1

Specification forming part of Letters Patent No. 26,68 l dated .Ianunrylh lGO.

I the ginning cylinder and brush. Fig. 2 is an end view, with the door remov'ed.

Our improvement consists in surrounding a portion of the grinning-cylinder with smooth metallic bands or ribs, so placed as to be concentric, or nearly so, with their outer surface, and just above the line of the points ofthe gin-roller. These bands or ribs are shown at A A A A, Src. They are placed about onehalf inch apart, (more or less,) and are from -onethirty second to onesixteenth of an inch (more or less) in thickness and aboutoneeighth of an inch (more or less) in width. They are placed over that portion of the ginning-cylinder upon which the cotton is placed, and where the principal portion of the ginning is done, and are concentric, or nearly so, with the circumference. `The under side of these bands are immediately upon the extremity of the teeth of the cylinder, or might be placed beneath the surface of the cylinder in concentric groves, provided the upper surface projects, as stated, beyond the extremity of the teeth 0f the cylinder.

In the drawings, B represents the ginningroller; c, the brush. The bands are fastened at D by a staple or any other mode to the inclined board E, and at the other end, F, by a screw and nut, or in any other convenient manner.

The operation of this machine is as follows: The cotton to be ginned is thrown inthrough the opening G, and falls and in part rests upon and is supported by thesmooth metallicbands A A A A A, Src. These `bands supporti the material in part thrown in, and as gin-teeth u revolve the friction createdby part of the Ina- H terial resting on these `bands and a part car-` ried forward by the gin-teeth causes a ginning operation along the whole length of the rib.

rlhe ribs also prevent fthe trash from being acted upon by the gin-teeth. The seeds fall` through the opening H, while the ,cottonis carried up, and the nal 'ginning is done at K against eithera movable revolving doctor, or in any other convenient manner. The advantage of the bands is thatthe ginning is effected` more expeditiously and in a `superior manner by reason of the `operationfbeing performed l over a large' portion `of the; cylinder, instead.`

of exclusively at the point K, and the trash is not taken up and mixed with the staple.`

Thesize and relative position of themetallic bands might be varied without affecting the operation of the machine.

Having thus described ourimprovement,` what we claim as our invention, and desire to secure by Letters Patent, is-

The arrangement of `stationary metallic Y bands AA A A A, Src., arranged concentric with and around either the whole 0r a part of the circumference of the gin-cylinderand just above the end of the gin-teeth, in the manner and for the purpose herein specified.;`
