JOHN W GUYNE$, OFCAL'VERT, TEXAS.
LINT-CLEANING ATTACI-IIYIENT FOR COTTON GINS.
Application filed September 3, 1921. Serial No. 498,194.
To all whom it may concern:
Be it known that I, JOHN W. Gorrrns, a citizen of the United States, residing at Calvert, in the county of Robertson and State of Texas, have invented certain new'and use ful Improvements in a Lint-Cleaning Attachment for Cotton Grins, of which thefollowing is a specification.
This invention relates to new and useful improvements in a lint cleaning attachment for cotton gins.
Oneobject of the invention is to provide .an attachment of the character described which may be readily applied'to cotton gins and which has been specially designed for the purpose of freeing from the lint all motes andheavy particles of dirt and the like as well as the dust, broken lint and lighter particles of foreign matter.
Another object is to provide a lint cleaning attachment which will thoroughly cleanse the lint during the process of ginning, and thereby materially raise the grade of the cotton being ginned.
A further feature resides in the provision of a device of the'character described which is of simple construction, and which may be cheaply and easily manufactured, and readily applied to the gin.
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 which is given in this specification and 35 illustrated in the accompanying drawings,
wherein The figure is a longitudinal vertical sectional view of the attachment, as applied to a gin.
Referring more specifically to the drawings the numeral 1 designates the gin stand, which may be of any conventionalform. Mounted in this stand there is a transverse shaft 2 upon which the gin saws 3 are fixed, 45 the saws being spaced apart by the space blocks 4:, and worliing between the ribs 5.
Back of the saws there is the transversely arranged suction flue 6 through which suction is created by means of any suitable so means, preferably a suction'fan (not shown) The seed cotton is fed to the saws in the usual and well known manner common to gins now in general use.
The saws strip the lint from the seed while the seedare held by the ribs 5, and the lint is carried throughbetween said ribs while the seed are discharged, when freed from the lint, in the usual manner.
The motes and other heavy particles of foreign matter contained in the lint are thrown by centrifugal force of the saws'into a chute leading from the saws and entering the suction flue 6. This chute is formed of the top and bottom walls 7 and 8 and suitable side walls which enclose the same. This chute is gradually contracted from the saws toward the suction flueand its bottom wall 8 declines, as shown so that the motes and other foreign matter thrown into said chute will move down along it toward the contracted throat thereof. This throat is formed by means of the shutters 9and 10 which are hinged 'together and' the former of which is also'hinged to the suction flue 6.
The free edge of'the shutter 10 overlaps, and
lies upon the top wall 7 of the chute. -The ends of these shutters normally rest upon the corresponding side walls of the chute and said shutters may be elevated or low- :ered through the hand lever 11 which is pivoted to the flue 6 and connected to the shutter-9 through the link 12. In case the This current assists in ridding the lint of the motes etc. and in carrying them through the chute.
The current may be controlled by adjusting the section 13. vVhen this section is adjusted toward the saws the current will be made stronger and when adjusted from the saws the current will be weakened. This variation of the current will be necessary as the condition of the cotton varies. It will be noted that the chute is comparatively wide adjacent the saws so that the current will be distributed and will not be strong enough to pull the lint from the saws, but the throat of the chute, being contracted, will cause a strong current of air through said throat, which will readily carry allot the motes and dirt through the throat and into the flue 6. If it is desired to cut off the current entirely from the saws this may be done by opening the shutter 10. The motes and foreign matter will then be freed from the lint by the centrifugal force of the saws alone. The current through the chute may also be varied by partially opening the shutter 10. The position of this shutter may be readily controlled by any well known form of adjusting contrivance suitable for this purpose.
The numeral 15 designates an air blast pipe which has a branch 16 terminating in a wide blas't nozzle 17. This nozzle projects a wide blast of air tangentially against the saws and blows the lint from the saws into the gin flue 18. The inlet end of the flue 18 is arranged adjacent the saws underneath, the nozzle 17 and into which the nozzle projects its blast of air. The gin flue enters the upper side of the transverse lint flue 19 tangentially and discharges said lint in a loose and flufly mass into said flue 19. Since the air current enters said flue 19 tangentially it sweeps around the wall thereof as it moves toward the discharge end thereof and sweeps the lintaround said flue.
The lint flue is mounted in a vacuum box 20 which encloses the underside of said flue from end to end. The enclosed under side of the lint flue is perforated and as the lint is swept therearound all the fine par ticles of dirt, foreign matter and broken fiber are forced through the perforations of the lint flue into said vacuum box 20. The
bottom of this box is formed into a convey or chute 21 in which there is a rotatable 'spiralled conveyor, by which said foreign matter is discharged from the box.
It is contemplated that there will be a battery of gins arranged side by side in actual use. As a rule five or six gins will constitute a battery, and it is to be noted that the flue 6, the air blast pipe 15 the lint flue 19 will be common to all of the gins of the battery.
What I claim is 1. The combination with a gang of gin 1 saws, of a suction flue, a. chute having outward converging walls and leading from the saws and entering said flue and means controlling the end of said chute adjacent the saws to regulate the current of air pass 1 ing therethrough.
Y 2. The combination with a gang of gin saws, of a suction flue, a chute leading from said saws and entering said flue, one wall of said chute being formed with an opening, a hinged shutter controllin said opening, said shutter being arranged to admit air through, or exclude it from said opening, and a lint flue disposed to receive the lint, and convey it from the saws.
4. The combination with a gang of gin saws, of a suction flue, a chute leading from the saws and entering the flue, said chute having a contracted throat adjacent the flue, and means for varying the capacity of said throat.
5. The combination with a gang of gin saws, of a suction flue, a chute leading from the saws and entering the flue, one wall of said chute being formed of hinged shutters which form with the opposite wall a contracted throat, means for adjusting said shutters toward and from the opposite wall of the chute to varythe capacity of said throat, and a lint flue disposed to receive the lint and convey it from the saws.
6. The combination with a gang of gin saws, of a suction flue, a chute having outward converging walls and leading from the saws and entering said flue and means controlling the end of said chute adjacent the saws to regulate the current of air passing therethrough, a lint flue disposed to receive the lint from the saws and one side of which is toraminated and a vacuum box surrounding said foraminated side.
7. The combination with a gang of gin saws, of a suction flue, a chute leading from the saws and entering said flue, one wall of the chute having an adjustable section adjacent the saws, means for adjusting said section toward and from the saws, said chute being contracted adjacent the flue, a lint flue disposed to receive the cotton from the saws and'one side of which is foraminated, a vacuum box surrounding said foraminated side and means for creating air currents through said flues.
8. The combination with a gang of gin saws, of a suction flue, a chute leading from the saws and entering said flue, one wall of the chute having an adjustable section adjacent the saws, means for adjusting said section toward and from the saws, said chute being contracted adjacent the flue, a lint flue disposed to receive the lint from the saws, said lint flue having a foraminated side, a vacuum box surrounding said toram inated side and a conveyor in said box.
9. A lint cleaning attachment for cotton gins including the combination with a gang of gin saws, of a suction flue, and a blast flue, a chute leading from the saws and entering the suction flue and being comparatively wide adjacent the saws and contracted adjacent said flue, said blast lint flue having one side foraminated, a vacuum box surrounding said foraminated side, and a lint conveying pipe entering said blast flue tangentially and leading from said saws through which the lint is delivered by an 10 air blast from the saws to the blast flue.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN W. GUYNES. Witnesses E. V. HARDWAY, W. H. DUNLAY.
