ADJUSTABLE LIP FOR LINT DUCTS Filed March 24, 1934 C IIIII/L John A. St reun 3 m Emu gs/ 55M Patented Mar. 16, 1937 ADJUSTABLE LIP FOR LINT DUCTS John A. Streun, Sherman, Tex., assignor to Hardwicke-Etter Company, Sherman, Tex., a. corporation of Texas Application March 24, 1934, Serial No. 717,148
10 Claims.
My invention relates to an adjustable lip for the lint ducts employed on cotton gins.
The lint in the ordinary cotton gins is sometimes removed therefrom by a strong draft of air which engages the lint upon the gin saws and carries it through a lint duct from the machine. As-the cotton passes into the lint duct it may engage over the margin of the duct on the inner side thereof in such manner as to clog the operation of the gin. This is particularly the case where the cotton is apt to be stringy and have impurities therein. Where the cotton thus lodges over the lip duct it becomes necessary to introduce a rod or stick and remove the lint l5 from the lip and this usually must be performed during the operation of the gin. It is an exceedingly dangerous operation and is avoided as far as possible.
It is an object of my invention to provide a 29 lip for the lint duct which may be swung out of position adjacent the ginning saws so that the material may be removed easily and without danger to the operator.
It is a further object to provide means for 5 swinging the lip into position away from the saws in such manner that the lint tends to drop away from the lip and be more easily removed from the gin.
In the drawing herewith I have shown a central vertical section through a gin upon which my invention has been employed.
The gin illustrated in the drawing is intended to represent the usual gin employed in ginning operations. There is a frame 2, supported upon legs I, and having an outer housing 3 protecting the interior working parts. Mounted in the frame is a shaft 4, upon which the gin saws 5 are mounted, said shaft having hearings in the side portions of the frame and rotatable by the usual means in the counterclockwise direction indicated by the arrow.
The cotton is fed to the ginsaws through a gin breast 6 and is carried into contact with the gin saws by the picker roll 1. Below the picker roll is a hull conveyor 8, which carries from the gin breast the hulls from which the cotton lint has been removed.
The cotton is caught by the gin saws and carried between the huller ribs 9 and moved up into the roll box ID, from which it is gradually engaged by the saws and carried past the gin ribs I I, which serve to remove seeds from the lint and allows them to drop downwardly through the outlet I2.
5 The forward portion of the roll box is formed by a door l3 mounted to swing outwardly so as to give access to the roll box.
The cotton lint carried by the saws past the ginning ribs is moved downwardly past the air nozzle 14 into the suction tube l5 through which it is carried from the gin. The motes which are carried around with the lint by the gin saws are thrown off to the rear into the chamber l6 and dropped therefrom into the trough ll, from which they are carried out of the gin by the mote conveyor l8.
Upon the upper end of the nozzle is mounted a curved mote board i9, which is adapted to be swung to and from the gin saws so as to prevent the motes from being drawn back into the lint, so as to contaminate the same.
The lint duct l5 has on its forward side below the gin saws a lip indicated at 20, which has its upper edge rounded so that lint will not engage thereon further than can be avoided. This lip I mount upon a swinging plate 2|, which forms the forward portion of the lint duct at that point, said plate being hinged to swing at 22 upon the lower portion of the lint duct. At the ends of this plate 2| are reenforcing plates 23 forming part of the swinging lip.
Engaged with the side plates 23 are links 24, which are secured at their outer ends at 25 to the inner end of the arm 26 upon the lever 21. Said lever is pivoted at 28 in the frame of the gin so that when the lever arm 21 is swung upwardly into the dotted line position the link 24 will be operated to pull the swinging lip downwardly away from the gin saws into the position shown in dotted lines in the drawing. It will be obvious that in this position the material caught around the upper edge of the lip will tend to drop off and by the use of a rod or scraper all the material may be easily removed from the lip. Thus the operator is able to very effectively clean the lip without coming into the vicinity of the rotating saws. When the material has been removed the lever arm will swing back into its original position.
The use of this swinging lip makes it possible to perform what has previously been a very dangerous operation without danger to the operator and in a manner more effective than is possible with the usual construction. The operation is not only greatly expedited and made more effective but the usual danger to the operator is eliminated. The further advantages of the device will be obvious to those skilled in the art.
What is claimed is:
l. A cotton gin including in combination a set of gin saws, a lint duct leading from said saws, a lip at the entrance of said duct, a pivotal support for said lip, and means to adjust said lip to a position extending downwardly away from said saws where material on said lip may fall therefrom.
2. A cotton gin including in combination a set of gin saws, a lint duct leading from said saws, a lip adjustably mounted at the entrance of said duct, and means to swing said lip from operative position adjacent said saw to inoperative position with its upper end pointed downwardly away from said saw.
3. In a cotton gin a lint duct, a lip at the entrance of said duct, a pivot for said lip, a control mechanism to swing said lip on its pivot to a position with its upper end extending downwardly away from said duct to discharge materials depositing thereon.
4. In a cotton gin a lint duct, an upstanding lip pivotally mounted at the entrance to said duct to direct the lint into said duct, and means to tilt said lip on its mounting to swing it to a position with the upper end spaced downwardly away from said duct to facilitate the removal of the lint from said lip by gravity.
' 5. In a cotton gin having a movable upwardly extending lint duct lip, the combination with the lip of a control mechanism to reverse the position of said lip from its upwardly extending position to a downwardly inclined position so that material adhering to the lip may be removed without interrupting the operation of the gin.
6. In a cotton machine, a rotating saw, a lint duct adjacent said saw, an adjustable lip for said '7. A cotton gin comprising in combination a set of gin saws, a suction lint duct adjacent the lower edge of said saws through which the lint is adapted to be drawn from said saws, a lip be-' low said saws forming the entrance to said duct, a pivotal support for said lip, and means to tilt said lip on its support away from said saws so that the lint caught on said lip may be removed therefrom while the gin is in operation.
8. In a cotton gin including a gin saw cylinder and a lint duct adjacent thereto, the combination of a lip on the said duct below said saw cylinder, said lip being supported at its lower end and having its upper end projecting upwardly to a point spaced slightly from said cylinder, and means to move said lip to an inverted position with the said upper end projecting downwardly away from said saw.
9. In a cotton gin the combination of a set of gin saws, a lint duct leading from said saws, a lip at the entrance to said duct, and pivoted at its lower end, a link connected with said lip, a lever connected with said link, said link normally holding said lip in fixed operative position but adapted when said lever is moved downwardly to swing said lip into inoperative position, with said lip extending downwardly away from said saws whereby lint can be removed from said lip.
10. In a cotton gin including a gin saw cylinder and a lint duct adjacent thereto, the combination of a lip on said duct below said saw cylinder, a pivotal support for the lower end of said lip, a pivoted lever, a link pivoted to said lever and to said lip, said link and said lever forming a toggle joint acting normally to hold said lip rigidly in position adjacent said saw cylinder but adapted when said lever is swung on its pivot to move said lip downwardly away from said saws.
