To all whom it may concern:

Be it known that I, JAMES L. MoGINN, J r., a citizen of the United States, residing at Columbus, in the county of Muscogee and State of Georgia, have invented new and useful Improvements in Cotton-Grins, of which the following is a specification.

This invention relates to cotton gins and particularly to the application of an improved form of mote board or plate.

The primary object of the invention is to provide a strong and durable form of mote board or plate having a simple and cheap construction and which may be adjustably applied to the bottom edge of the lint fine to reinforce and strengthen the latter and keep it straight or in proper alinement with relation to the gin saws, the mote board or plate being readily adjustable toward or from the gin saws.

Vith this and other objects and advantages in view, the invention consists in the construction and arrangement of the several parts which will be more fully hereinafter specified.

In the drawing: Figure 1 is a section through a portion of a gin showing the improved mote board or plate applied thereto, the latter being also shown in cross section. Fig. 2 is a detail perspective view of the improved mote board or plate.

The mote board embodying the features of the invention is shown applied to a' gin provided with an air trunk or conduit in operative association with blast fans, not shown, and having an air delivery outlet or spout adjacent to the saws to liberate the lint cotton from the latter and drive it into the lint flue, but it will be understood that the mote board may be used with a gin embodying a brush cylinder cooperating with the gin saws in a manner which will be read ily understood by those skilled in the art.

In the drawing the numeral 1 designates the air trunk or conduit, 2 the outlet, 3 the gin saws, and 4 the lint flue, the latter being supported in operative relation to the gin saws as shown as well as to the extremity of the outlet 2 and whereby the lint cotton may be blown from the saws downwardly into the lint flue. The bottom of the lint flue has the extremity thereof adjacent to the saws slotted as at 5 for obvious reasons, and the edge wall or bottom edge 6 of this flue has the improved mote board or plate 7 adjustably fitted thereover.

The mote board or plate 7 is constructed of suitable sheet metal and doubled upon itself as at 8 about midway of its width to form a seat or recess 9 for the reception of the bottom edge 6 of the lint flue 4, the bent portion 8 terminating in a right-angular flange 10 which is strengthened by rebending the metal to increase the thickness of the same, and therethrough near opposite ends screw-threaded openings 11 are formed. The mote board or plate as a whole is given a transverse curvature corresponding to the contour of the bottom portion or wall of the lint flue over which it is fitted to follow out as nearly as practicable the curve of the said bottom portion or wall of the lint flue to avoid obstruction of the movement of the lint cotton over the mote board into the flue. The one edge 12 of the mote board,'which bears against the inner surface of the lower portion or wall of the lint flue is formed as a downwardly curved lip so as to set up a snug engagement thereof with the said wall of the lint flue, the mote board having suliicient inherent resiliency to maintain a close engagement of the edge or lip 12 with the lower portion or wall of the lint flue when the board is applied over the edge 6.

The lint flue has a depending rib or flange 13 adjacent to the edge 6 to codperate with the flange or rib 10 of the mote board 7 and through the two flanges l0 and 1-3 and engaging the openings 11 adjusting bolts 14: are inserted and of such length as to admit of a considerable movement of the mote board to and from the saws 3. The adjusting bolts 14 are provided with suitable nuts for holding and setting the bolts and mote board in adjusted position, said nuts being applied as at 1.5, see Fig. 1.

In applying the mote board it is inserted in the slot 5 and the edge 6 at the bottom of the flue 4 is caused to enter the seat or recess 9, the doubled or bent edge of the mote board being nearest to the saws and maintaining a straight edge in relation to the latter. As above indicated, the mote board may be adjusted toward and from the saws through the medium of the bolts 14, and when the edge 6 is covered by the part of the mote board engaging the same it is obvious that said edge is reinforced or strengthened and bending or buckling thereof will be prevented. The mote board not only serves the important function of a device of this character, but also renders the portion of the lint flue which it engages stronger and more durable with material advantages in the economical operation of the gin.

It will be observed that the upper portion of the mote board or plate rests closely against the bottom of the flue 4 and the lip 12 at the lower side edge of the mote plate, or at the side edge opposite that nearest the saw closely bearing against the upper surface of the part of the bottom of the flue 4 over which it extends prevents the aggrega tion of dust or particles of cotton between the bottom of the lint flue and the part of the mote board or plate extending over said bottom. Furthermore, by disposing the flange or rib 10 at the under side of the mote board or plate and bending it at an angle to constitute a terminal parallel with the flange or rib 13 of the bottom of the lint flue t a convenient and practical adjusting cooperation of the two flanges or ribs 10 and 13 will ensue, and as hereinbefore noted the adjusting bolts 14 will be long enough to permit quite an extensive adjustment of the mote board or plate and the adjustment of the said mote board or plate may be effected without separating the adjusting bolts from the flanges or ribs 10 and 13 and in view of which operation the mote board or plate will be caused to slide over the bottom of the lint flue in opposite directions in accordance with the right or left rotation of the adjusting bolts. The improved mote board is also of such construction that it can be readily applied to the lint flues of gins now in use at a minimum expense and to accommodate various applications, changes in the proportions and dimensions may be adopted with- R out modifying the essential features of construction constituting the invention.

What is claimed is:

The combination with gin saws having means cooperating therewith for disengaging lint cotton therefrom, of a lint flue in operative association with the saws and having a depending rib and a mote board doubled upon itself to form a seat to receive the lower edge of the lint flue, the doubledover portion of the board terminating in a depending rib which adjustably cooperates with the rib of the lint flue, the mote board also having a lip at its lower edge within the lint flue which snugly engages the latter, and adjusting means engaging the two ribs and operative to move the mote board on the lower edge of the lint flue.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
