UNITED ST TE JAMES C. GARNER, OF HOUSTON, TEXAS.

Application filed March 17, 1919. Serial No. 283,203.

To all whom it may concern:

Be it known that JAMES C. GARNER, a citizen ot' the United States, residing at Houston, in the county of Harris and State of Texas, has invented certain new and useful Improvements in a Gin, of which the following is a specification.

This invention relates to new and useful improvements in a gin, and has more particular relation to a ,gin for cotton and other similar fibrous material.

One object of the invention is to provide a machine of the character described, which has been specially designed for the purpose of separating lint cotton from the cotton seed and also for separating the bolls, stems, leaves, motes and other foreign matter from the lint, and for collecting said lint and foreign matter separately, and discharging them separately from the gin.

Another object of the invention resides in the provision of an improved form of roll box, wherein the seed cotton is collected and held within the range of the Saws, to be operated upon by saidsaws for the purpose of stripping the lint from the seed.

A further feature of the invention resides in the provision of means for cleaning the lint, after it hasbeen separated from the seed, from the gin saws, said separating means including an air blast nozzle, through which an air blast is discharged against the saws, and a suction nozzle through which an air suction is created to collect the lint from the saws and deliver it into a lint flue through which it is delivered to the con denser.

A still further feature of the invention resides in the provision of an improved form of air inlet pipe and blast nozzle, said pipe being so mounted in the casing, that it may be revolved on its own axis so as to carry the nozzle away from the saws, to permit access to the saws and nozzle for the purpose of inspecting and cleaning the same.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of whichis given in this specification and illustrated in the acompanying drawings, wherein:

Figure 1, is a front elevation of the gin shown partially in section, taken on the line 1-1 of. Figure 3.

Figu 2, is a r r'el ve ion th of; hown partially in section, taken on the line 22 of Figure 3.

Figure is a transverse sectional view taken on the line 3-3 of Figure 1.

Figure 4, is an enlarged fragmentary sectional view taken on the line 3-3 of Figure 1, and showing a fragmentary view of the saw, and the air blast nozzle in its relation thereto, and

Figure is an end view, shown partially in section.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numerals 1, indicate the end plates of the casing which are provided to support the operative mechanism of the gin. Pivoted between said plates in the upper part of the casing in front, is a frame, consisting of the

ends

2, 2, suitably secured together, as hereinafter explained, and having its front side formed of the breast 2, which is hinged to the frame so as to be readily opened and closed, and at the rear of the gin, there is the shutter, 3, said shutter being hinged between the

end plates

1, 1, so as to be readily opened to permit access to the interior parts, from the rear. The numeral 4, refers to a transverse shaft which is rotatably mounted in suitable bearings 5, which are carried by the ends of the casing, and fixed upon this shaft are the circular gin saws 6, which are spaced a uniform distance apart on said shaft by means of the annular spacers 7, interposed between the saws. These saws are suitably serrated, so as to engage with the lint and strip the same from the seed. Rotation is imparted to the shaft 4, and the saws through a suitable pulley 8,. which is fixed upon one end of said shaft.

Transversely disposed in front of the saws and beneath them is the picker roller 9, which is fixed upon the shaft 10, rotatably mounted

end bearings

10, 10, carried by the respective ends 2, Q, and said roller has spikes 11 projecting out from its periphery. Behind the picker roller there is arranged a plurality of huller ribs 1:2, whose lower ends are secured to the transverse bar 13, and whose upper ends are secured to the transverse bar 14, said bars serving to connect the

frame ends

2, 2. These huller ribs are arranged to alternate with the saws, and are spaced a sufficient distance apart to permit the lint and seeds to pass between them, but they arrest all bolls, stems, leaves,

1 seed cotton collects in and other foreign matter which may be in the cotton, and prevent the passage of this foreign matter into the roll box, hereinafter described. The seed cotton passes down behind the huller breast a-nd is engaged by the spikes of the picker roller and by them. carried into engagement with the saws, and the seed cotton is carried said saws through between the ribs 12 into the roll box, but the foreign matter is arrested by said ribs, and drops down onto the picker roller, and is by it, discharged down onto the seed board 15. However, the free ends of the spikes 1.1 are retracted, or bent back, so as to readilyrelease the cotton and not to carry any. part thereof around out of range of the saws, Spaced behind the huller ribs 12, are the stripper ribs 16, whose lower ends are secured to the transverse bar 17, and whose upper ends are secured to the transverse bar 13, said bars 17 and 18, being secured at their respective ends to the frame, ends2, 2, and securing said ends of said frame in fixed position relative to each other. These stripper ribs are arranged alternately with respect to the saw 6, and are closely spaced to prevent the passage of seed through between them, but they permit the passage of the lint cotton, motes, and other small particles. The upper ends of these ribs are extended, and arcuate in form, forming the back side of the roll box, which is smooth and free of lint-engaging projections, and the'opposite side of said roll box is formed by the rollbox-breast 19, which isarcuate in cross section, and whose upper edge is swung from the transverse rod 20, the lower ed e of this breast resting upon the bar 14.. The roll box breast 19, and the opposing ends of the stripper ribs 16, are oppositely curved, so as to form between them, a substantially cylindrical roll box, with-smooth interior walls, in which the a mass, and through which the saws 6, pass as they rotate, These saws pass through the cotton in said roll box, and engage with the lint thereof, and cause the mass of cotton in said box to rotate with a constant rotary movement, thereby coming constantly into contact with said saws which strip the lint from the seed, said lint passing through between the strip per ribs, but the seed being arrested thereby, and when freed, from the lint, gradually working from the roll and dropping onto the retaining board 31, and passing thence down between the ribs 12. and 16, onto the seed board 15. The retaining board 31, is secured to the transverse shaft 32, which is rotatably mounted in suitable bearings in the frame ends 2. 2, and the free edge of said board is slotted, forming fingers which are spaced a uniform distance apart, and which project between the respective saws 6. One end cf the shaft 32 has the handle 33, fixed thereon, through which the angle of said retaining board may be adjusted, so as to retain the seed the required length of time until all of the lint is stripped therefrom.' The seed board 15 is fixed to a centrally located shaft 21, whose respective ends have bearings in the

end plates

1, 1, of the casing. When the said board declines forwardly, as shown "in full lines in Figure 3, it will deflect the seed and, other foreign matter out toward the front of the gin, but it'may be turned in the position shown in dotted lines in Figure 3, and it will then deflect the seed and other foreign matter a.

and through which an air blastisdischarged downwardly against the saws to blow the lint cotton therefrom. 'This air blast has the effect of separating the lint into a loose mass. The pipe 23 is, mounted inbearings in the

end plates

1, 1, and is capable of partial rotation therein,so that said pipemay be rotated on its own axisin the direction shown by the arrow in Figure 1, thus withdrawing the nozzle 24 from the saws. Provision is thus made for gaining access to the saws and nozzle when it is desired to clean or inspect the same Supported by the end plates 1., 1, and arranged underneath the pipe 23, is a suction lint flue 25, formed with an elongated suction nozzle 26, which extends the full length of the saws, and which is. arranged underneath and in front ofthe-air blast nozzle 24. The rear wall of this nozzle is extended, forming the apron 2.6, which is arcuate in form, and which extends up around the saws, to the nozzle 24, forming a support for said last mentioned nozzle. The lint cotton freed from the saws by the blast issuing from the nozzle 24 is collected by the suction nozzle 26, and carried through it into the lint flue 25, and is carried thence to the condenser. This suction nozzle also collects all loosetibre blown out from the mass of lint by the air blast nozzle 24, and which would otherwise-pass out into the air and be wasted. I am awarethat an air blast has heretofore been used to clean the lint cotleaves said nozzle passinginbetweensaid saws and a part passlng outbeyond and missing. t e saws entirely thu m k ng: it

[iii

difiicult to recollect the lint and causing a considerable amount of the fibre to be blown out into the open air and wasted. I am also aware that a suction nozzle has been heretofore employed in ginning, for the purpose of cleaning the lint from the saws by suction, but when used alone with the form of suction gin, commonly employed, it must be so constructed to create a sufficiently strong current that it is liable to become clogged, and will also tend to compact the lint into dense lumps or masses, but the combination of an air blast nozzle with a suction nozzle has not heretofore been used for thus purpose, and this combination is particularly advantageous for the reason that the air blast will separate the lint into a loose uniform mass, and the suction nozzle will then draw the lint so formed into the lint flue and will collect the stray particles of fibre blown out by the blast nozzle. By means of this combination, the saws will be completely cleaned of lint, all of which is collected into the lint flue in a loose, clean and evenly formed mass, and in proper condition to be delivered to the condenser to be formed into a bat, preparatory to baling. Furthermore the suction through the lint flue delivers the lint so rapidly that it does not become con gested in said flue, and if the lint should become ignited, on account of friction of the saws, or from any other cause, as often ha.p pens, there will only be a small amount of lint in the lint fine to burn, and the fire may be therefore more quickly extinguished.

As heretofore stated, the ribs 16 are spaced apart a suliicient distance to permit motes and other small particles to pass between them. These particles are thrown, by centrifugal force of the saws, from the lint and pass out over the air pipe 23, and are caught in the long transverse hopper 27, arranged at the back side of the gin. This hopper has a delivery belt conveyer 28, which travels over the

idler rollers

29, 29, and is driven by a suitable driving roller 30. This conveyer receives the particles delivered by said hopper and carries them from the gin to any suitable receptacle provided for them.

The frame hereinbefore referred to is pivotedly mounted in the casing through the medium of the transverse rear bar 34. The ends 2, 2, of the frame, as Well as, the stripper ribs 16, are fixed to this bar 34, and it is pivoted at its respective ends to the

respective end plates

1, 1. Beneath the lower end of the frame, there is a transverse shaft 35, which has bearings in the

respective end plates

1, 1, and a manual lever 36, is fixed to one end of this shaft. Each end of the shaft is connected to the lower part of the frame on each side by means of toggle levers, as 37. \Vhen the manual lever 36, is p ll d d wnwa dly, it Will operate through said toggle levers to carry the lower end of the frame outwardly, thus completely freeing the saws. This is often necessary inasmuch as foreign objects often get into the roll box, and which must be removed, or when it is desired to stop the operation of the ginning in case of fire or for any other purpose. iVhen this frame is so swung out, the operation will cause a slack in the belt 37, through which the picker roll 11 is driven, and this stops the delivery of cotton by said roller.

TV hat I claim is:
