To all wwm t may concern:

Be it known that we, WILLIAM H. MOR- TON and MORRIS ROBINSON, citizens of the United States, and residents of Newark, in the county of EsseX and State of New Jersey, have invented certain new and useful Improvements in Cotton-Gins, of which the following is a specification.

rllhe objects of this invention are to provide an improved cotton gin in which the seeds of the cotton will be thoroughly cleaned and the full strength of the fiber of the cotton retained; to prevent cutting or wedging the seed; to adjust the knife with respect to the ginning roll; to positively and effectively remove the cotton from the ginning roll; to concentrate the discharge of the cotton by the lint iue; to support the feeding hopper and ginning roll independent of each other; to provide an improved grid; to secure simplicity of construction andoperation, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views;

Figure 1 is a side elevation of a cotton gin of our improved construction with part of the feeder broken away;

Fig. 2 is an end elevation looking from the left of Fig. 1;

Fig. 3 is a central transverse section as on line A-A of Fig. l;

Fig. 4 is a longitudinal vert-ical section through the ginning roll showing a portion of one end of the cotton gin;

Fig. 5 is a detail view of the blade supporting plate and cotton blower pipes, and

Fig. 6 is a detail face view of a blade and j a wedge for adjusting the same.

In the specific embodiment of the invention illustrated in said drawings, the reference numeral 1 indicates a base or bed of suflicient length and breadth for the purpose having housings 2, 3 at its opposite ends in substantially parallel relation, said housings being preferably as wide as the base. Between the housings, and supported by the base, are standards 4, 4, shown adjacent the `.time fitting freely enough housings and of substantially the same height, and upon the same is a feeder 5 of any suitable or well known construction providing means 6 for blooming and feeding the cotton to ginning rolls 7 next described.

Extending between the housings 2,3, and supported in suitable bearings 8 therein, is a pair of separated parallel shafts 9 both in the same horizontal plane, said shafts extending through thestandards 4, 4. Fast upon these shafts are wheels l0, 10 supporting upon their rims cylinders 11, 11 preferably made up of longitudinal slats l2; Each cylinder, furthermore, is coveredwith felt 13 or other material to which the cotton will adhere. Preferably also, each cylinder is proportioned in length to just fit between the standards with suiicient eXactness to `prevent cotton from entering between its lends and the standards.

lThe end wheels l0 carrying each of the cylinders extend partly out of the same, see Fig. 4, and the standards are circularly recessed as at 14 to receive and lit around the wheels close enough to prevent vibration thereof but at the same to not materially affect rotation of the roll.

are separable upon a horizontal plane vthrough the shafts so the upper portions 15- kof the standards may be removed for replicity ofv studs projecting radially from its surface adapted to coact with the ginning roll to feed the cotton and carry any excess amounts back to be refed. These picker rolls are supported in bearings 20 in the housings and are driven by gears 2l in mesh with gears 22 on the ginning rolls,

The standards preferably at the opposite end of the gin from the above described gears for driving the ginning rolls.

Aln1ife23 is'.` provided for each o-f the ginning rolls, arranged longitudinally there- Vof with its sharpened edge adjacent the ginning Vv,roll toward the picker roll. The cotton adhering to the felt covering of the ginning roll passes between the same and the knife, the space therebetween being too l small to yadmit the seed. A suitablefbraeket 24 is provided for supporting each knife, the same being here shown as having a longitudinal portion terminated y by transverse flanges 25 adapted .to be secured to vthe housings. The knife lies flatwise'of the longi- Y the led-ge, force the knife toward the ginning vmit adjusting the blade.

tudin-al .portionl of the bracket and at the Vouter edge thereof the bracket provides a longitudinal ledge 26 substantially as thick as the knife. Overlying the ledge and a portion of the knife is a clamping plate 27 ,bolted er otherwise secured to the bracket,

v.the knife being slotted, asat 28 (see Fig.

roll when desired. By screwing the bolts down fast, theknife .will then be securely .held .in adjusted position. It will be understood that'lthe wedges are thin enough to be readily accommodated between the clamping plate 27 f and the longitudinal portion ofthe bracket, so as to be always in position tobe moved.r q Preferably means are provided for tilting the bracket, for use more especially in as- Y sembling the machine whereby the slight variations bound to exist incastings may be overcome to bring the knife to itsV proper relation with respect toitheginning roll. For -this purpose, the flanges 25 of the bracket may be bolted at one corner, for instance, to the housings, and are provided i vwith arcuate slots, the center fof curvature of which is at said bolt, through which a secondbolt may pass.' yThis permits the bracket to be swung te obtain the exact necv essary distance between tlieknife and roll,

after which the bolts yare screwed tight and the bracket clamped', fast thereby. ,c

Supportedby the clamping plate y27 yis a seed ,grid 30 comprising a, plurality of horizontal bars or wires 31 secured by upright supports 32 arran 'ed at suitable distances te prevent the wires from becoming bent. VArs shown, the end supports 32 may be secured to the standards and the vintermediete' Supportsmay' beblted .te the. dampplate 27. Ovrlyiiigthe upper 'f the supports 32 is a connecting strip 38 which will prevent the intermediate supports from becoming dislodged.

lBelow the ginning rolls is a lint flue 34 sloping downwardly toward the middle of the gin and providing a restricted passage 35 from which the cleaned fibers may be obtained. Within this lint flue and closely adjacent the ginning rolls are air passages 36 having lateral openings from which air may escape in jets directed toward the ginning roll for removing the cotton therefrom. As shown in the drawings, two air passages are provided for each roll, one adjacent and just below lthe knife and the other at the opposite side of the roll, but obviously more c or less of these air passages may be ein ployed as may be found desirable or necessary.

I have shown the jets of air adapted to issue through holes or perforations in the passages which are directed downwardly toward the periphery of the roll, so that the jets of the pair of air passages for either roll will be directed toward each other and thus against theroll in opposite directions with respect to its direction of turning. The effect of this is to very completely and thoroughly remove the fibers of cotton from the roll, because while the first jets of air beyond the knife strike these fibers from one diiection, the jets of air from the other or succeeding air passage strike said fibers from the other or opposite direction. Preferably the air passage below the knife is formed in theedge of the bracket v24k adjacent the periphery of the roll, and at one end of the gin all the air passages are connected by a header 37 which in turn is supplied with .compressed air by a pipe 38.

In operation, the cotton is passed through the feeder 5, and passes downward to the ginning rolls 7. It may be hei'e noted that the feeder is divided by a partition 40 which extends down as far as the ginning rolls so that the cotton will be distributed evenly to said rolls. The felt or other covering 18 of each ginning roll causes the fiber of the cotton to adhere thereto and passing the picker ioll 19 the fiber is drawn past the knife 3, separating it from the seeds which remain upon the grid 30 and are carried back by the picker roll if all the cotton is not removed. In this way all the cotton becomes ultimately cleaned off `of the seeds which will consequently have a greater commercial value in themselves and the entire value of the cotton also retained. The air jets remove the cotton from the ginning rolls within the lint flue after which it is discharged tl'ierefrom. Preferably intermediate standards 39 are provided between the ends of the knife which will support the same from the base and prevent any bowing of the knife under rapid operation of the gin. This positively prevents any seeds from wedging between the ginning roll and its knife.

Obviously various modifications and changes may be made in the manufacture of our improved cotton gin, and we do not wish to be understood as restricting ourselves eX- j,

cept as required by the following claims when construed in the light of the prior art.

Having thus described the invention, what we claim is,

l. The combination with a roll to which cotton will adhere and means for feeding cotton thereto, of a plurality of air passages parallel to the roll adjacent its periphery at a distance apart less than a semi-circumference, said air passages being all lower than the middle of the roll, and having outlets directed obliquely downward toward the roll in opposite directions with respect to the rotation thereof whereby the cotton will be blown off of the roll and will drop free therefrom, and means for rotating said roll.

2. lThe combination with a roll to which cotton will adhere and means for feeding cotton thereto, of a plurality of air passages parallel to the roll adjacent its periphery at a distance apart less than a semi-circumference, said air passages being all lower than the middle of the roll and having outlets directed toward the roll, the outlets of one air passage being inclined toward the other air passage whereby cotton will be blown 01T of the roll the same jets also carrying the cotton along to discharge it, and means for rotating said roll.

3. The combination with a roll to which cotton will adhere and means for feeding cotton thereto, of a plurality of air passages lower than the middle of the roll one of said air passages being at the side of the roll where its periphery is moving downward and the other at the side of the roll where its periphery is moving upward, both said air passages having downwardly directed outlets adapted to direct jets of air obliquely downward against the roll in opposite directions with respect to the rotation thereof whereby cotton will be blown oill of the roll and will drop free therefrom the same air jets which remove the cotton from the roll also carrying the cotton along to discharge it, and means for rotating said roll.

el.. In a machine of the character described, the combination with a ginning roll to which cotton will adhere and means forfeeding cotton thereto, of a knife adjacent the said roll adapted to remove the seeds from the cotton and permit the seeded cotton to pass between itself and the roll, a pivoted bracket supporting said knife, the line of pivoting of said bracket being parallel to and offset from the plane of the knife, whereby swinging the bracket will obtain maximum variation of the angle of the blade with respect to the roll and minimum movement of the knife edge radially of the roll, and means for clamping said bracket in adjusted position.

5. In a machine of the character described, the combination with a ginning roll, means for feeding cotton to said ginning roll, a knife for said ginning roll, a bracket carrying said knife and having at its ends transverse anges, pivotal bolts extending through the upper ends of said anges, and clamping bolts extending through arcuate slots in the lower ends of said flanges, whereby swinging the bracket will obtain maximum variation of the angle of the blade with respect to the roll and minimum movement of the knife edge radially of the roll.

6. In a machine of the character described, the combination with opposite housings, of a ginning roll rotatably supported thereby, means for feeding cotton to said ginning roll, a knife for removing the seeds from the cotton, a bracket extending between said housings and supported at its ends thereby carrying said knife, and means intermediate the ends of said bracket for supporting the same and preventing the bracket and knife from bowing in operation.

7. In a machine of the character described, the combination with a ginning roll and means for supplying cotton thereto, of a knife for removing the seeds from the cotton, a bracket supporting said knife having a ledge extending longitudinally of the knife at its back, wedges between said ledge and the knife back for moving said knife in its plane whereby the knife may be slid toward the roll to adjusted position, and means for clamping the knife to the bracket when so adjusted.

8. In a machine of the character described, the combination with a ginning roll and means for supplying cotton thereto, of a knife for removing the seeds from the cotton, a bracket supporting said knife having a ledge extending longitudinally of the knife at its back, said ledge being inclined rearwardly outward at its ends, wedges between said knife back and inclined ends of the ledge whereby the knife may be slid toward the roll to adjusted position, and means for clamping the knife to the bracket when so adjusted.

9. In a machine of the character described, the combination with a ginning roll and means for supplying cotton thereto, of a knife for removing the seeds from the cotton, a bracket receiving said knife flatwise upon itself and having a ledge extending longitudinally of the knife at its back, a wedge between said ledge and the knife back for moving said knife in its 4plane toward the ginning roll, and means for holding both llt knife and Wedges latwise on the bracket Y and clamping them when adjusted.

' passage extending longitudinally of the roll,

another air passage at the opposite side of the roll, said air passages adapted to d1s Copies of this patent may be obtained for .five cents each, by addressing the Commissioner of latents, Washington, D. C.

charge jets toward each other obliquely 10 against the periphery of the roll, one in the direction of turning of the roll and one in a direction opposite to that in Which the roll turns, and means at the end of the roll for supplying compressed air to said air pasl5 sages.
