This invention relates to a mote removing or like means for cotton gins, to be built as an attachment or initially into the cotton gin for the purpose of removing motes and other trash in 5' addition to the usual or any other mote removing means, during the process of ginning lint cotton.

It is particularly aimed to provide a relatively simple construction designed to catch the motes and other trash, as discharged by centrifugal force from the saws and particularly having a trough to receive the motes and other trash, which is removable from the trough in any suitable manner as by means of a conveyor, by air blast, suction or the like.

The more specific objects and advantages will become apparent from aconsideration of the description 'following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a fragmentary elevation of a huller brush cotton gin, embodying my improvements;

Figure 2 is a longitudinal sectional view through the parts of Figure 1;

Figure 3 is a detached view showing the supplemental means constituting the present invention, and

Figure 4 is a detail perspective view trough device.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, l generally designates fragmentarily, a huller brush gin of which the roll box is suggested at I l, preferably having a displaceable closure member l2 arranged to swing to open position on a pivot means fastened to the frame I4 of the gin. Within the box, are the usual cotton ribs l5 and huller ribs IS. A spiked roller ll co-acts with the latter ribs, in the usual manner.

The horizontal series of saws are shown at l8 having usual saw teeth I9, and which saws are or the movable in the direction of the arrow as shown.

fastenings 25 passed through openings 26, of an attaching flange 21 of the plate, to a transverse member 28 of the frame It. Such plate at its lower end is formed into a trough 29 of any desired configuration, for instance V-shaped as shown. On the other hand, it may have a flat 5 bottom or may have a rounded bottom as preferred. Such trough extends into the space between the saws l8 and brush 2ll,'relatively close to them, so that the motes and other trash thrown by the saws by their centrifugal action 10 during rotation, will be caught in the trough 29. The device is illustrated as applied to a brush type gin, where the application is made to an air blast type the trough is located between the saws and the air blast nozzlfi. This modification being 15 obvious and deemed unnecessary to be illustrated. This trough or catching means, is employed in addition to the usual or any other mote or trash catching means which may be built into or form a part of the gin. At the particular location of the trough, I find that much more of the motes and trash are removed, often in a suflicient quantity to cause the cotton to be graded at least a grade and oftentimes much more than a grade higher, consequently bringing a higher price on the market.

The motes and other trash caught by the trough 29 may be removed therefrom in any suitable way. In some types of gin, the same may be removed by suction, in others it may be removed 30 by air blast, but as shown, I prefer to use a conveyor device generally represented at 30. This conveyor device may have an endless belt 3i trained over pulleys 32 and 33 rigid on shafts 34 and 35. Shaft 34 is journaled in a suitable 35 bracket 36 which is fastened to a stationary part of the gin, for instance a part of the frame I4. On the shaft 34, a beveled gear wheel 31 is keyed and enmeshed therewith is a beveled gear wheel 38, keyed to a shaft 39 suitably journaled in the w bracket 36. On the shaft 39, is a pulley 40. The pulley 40 is adaptedto be driven in any suitable manner so as to operate the conveyor 30 and for instance by an endless belt 4|, =.trained over the pulley 40 and over a pulley 42, which is keyed to or fast on the shaft 22, which is the driving shaft of the saws Ill.

The shaft 35, is journaled in abearing 43 slidably mounted in a slot 44 of the bracket 45 which is fastened to a rigid part, for instance the frame m I Ill according to the adjustment desired. It will be noted that at intervals, flights or drags 48 extend outwardly from the belt 3|. Y

As a result of the construction described, the saws IS, in operation, will discharge motes and other trash by centrifugal force which will be caught by the trough 29, the same being in part deflected into the same by a deflector plate 49 opposed to the plate 24, and fastened at 49' to a member 50 of the aforesaid frame 14. The motes and trash thus caught in the trough 29 will be removed due to the fact that the conveyor 30 is positively driven from the saw operating shaft 22, through the medium of the pulley 42, belt 4|, pulley Ml, shaft 39, beveled gears 38 and 37, and pulley 32, the flights 48 or drags, causing the motes and other trash to be pushed out or positively moved out of the trough 29 and discharged at any suitable location and into any suitable means.

Various changes may be resorted to provided they fall within the spirit and scope of the invention. s

I claim as my invention:

1. In combination with saw means for engagement with linting cotton or the like, a trough disposed relatively close thereto to catch motes and other trash discharged therefrom by centrifugal force, means operable to remove the material caught by the trough, said trough forming part of a plate, said plate extending materially about the trough and being fastened at its upper edge, and a deflector plate above the trough in opposed relation to said plate.

2. In combination with saw means for engagement with linting cotton or the like, a trough disposed relatively close thereto to catch motes and other trash discharged therefrom by centrifugal force, comprising a. conveyor having flights operable in the trough, means to drive the conveyor from the saw means, comprising pulleys over which the conveyor is trained, a gear member rigid with one of the pulleys, gear means enmeshed with the gear member, a shaft to drive the gear means, and means to drive the shaft from the saw means.

3. In combination with saw means for engagement with linting cotton or the like, a trough disposed relatively close thereto to catch motes and other trash discharged therefrom by centrifugal force, comprising a conveyor having flights operable in the trough, means to drive the conveyor from the saw means, comprising pulleys over which the conveyor is trained, a gear member rigid with one of the pulleys, gear means enmeshed with the gear member, a shaft to drive the gear means, means to drive the shaft from the saw means, comprising an endless belt, a pulley on the shaft, and means adjustably mounting one of the first mentioned pulleys.

4. In combination with saw means for engagement with linting cotton or the like, a trough disposed relatively close thereto to catch motes and other trash discharged therefrom by centrifugal force, means operable to remove the material caught by the trough, said means having flights operable in the trough, and a deflector plate disposed between the trough and saw means covering the second mentioned means above those flights operating in the trough.
