COTTON-SEED LINTER.

Specification of Letters Patent.

Patented Mar. 14, 1916.-

Application filed December 16, 1914. Serial No. 877,544.

To all whom it may concern:

Be it known that I, HUGH E. SESSIONS, a citizen of the United States, residing at Columbia, Richland county, State of South Carolina, have invented certain new and useful Improvements in Cotton-Seed Linters, of which the following is a specification.

This invention has reference to cotton seed linters of the type disclosed in my prior Patents Nos. 962,722, June 28, 1910, and 1,077,435, November A, 1913, and has particular reference to that part of the mechanism where the lint is conveyed to the condenser.

The purpose of the invention is to prevent the clogging of the lint in the flue leading from the outlet of the linter to'the condenser and to evenly and properly distribute the material carried out through the flue on the surface of the condenser drum, whereby the product on the drum will be of practically uniform character from one end to the other, not only in thickness but in quality.

The novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings.

In the drawings, Figure 1 is a cross section of a linter having my invention therein, and Fig. 2 is a partial plan view showing the form of the flue leading to the condenser. As shown in the drawings, the linter is of the type shown in my patents above mentioned including the outer casing 10, the saw cylinder 11, the brush cylinder 14 and the mote-board 16. The rotation of the brush cylinder creates a current outwardly and upwardly at a considerable angle along the mote-board 16 and, as explained in my prior patents, this current carries the lint which has been separated from most of the motes and trash. The air current carrying the lint enters the flue leading from the outlet 17 to the condenser 30 and that flue, as ordinarily made, is about twenty-four inches long, but this length may, of course, vary. The outlet 17 extends practically the entire length of the linter and is therefore of substantially the same length as the brush cylinder. The end of the flue next to the linter is of sufficient width to fit over the outlet 17 and its bottom wall 9.6 is preferably level with the outlet leading from that point at a slight upward angle to the condenser.

' The top wall 27 leads from above the outlet and the Walls 26 and 27 are at an angle to each other flaring outwardly from the linter.

ing the end of the flue at the condenser of less width but of greater height than at the linter.v In linters as heretofore constructed there has been a tendency of the particlesof lint to fall to the inside bottom wall 26 of the flue and to collect there to such an extent that they would clog the flue and sometimes the lint would fall back into the linter down over the mote-board.

, According to my present invention I have so arranged the parts that the current of air and lint passing up over the mote-board will be partially deflected at the point where it leaves the linter and a portion of it will descend and strike the bottom inside wall I of the flue, thus preventing the collection of r the fine particles of lint at that point and picking up any particles which may rest there. In the present construction the condenser is placed at a somewhat higher level in reference to the linter than in my two prior patents above mentioned and the outvlet 17 is not made so large vertically. The

condenser may be raised three or four inches, but the invention is not limited to the exact amount and the outlet 17 is closed a corresponding amount. Air passing upward at an angle over the mote-board strikes the short board 29 at the upper edge of the 'outlet and because of the angle of travel of the air and the angle of this board, together with its relation to the lower wall 26 of the flue, a portion of the air will be deflected downwardly against the lower wall, as above indicated.

In the constructions heretofore used, the

form of the flue leading to the condenser has tended to cause cross currents because of the inclinations of the walls and the result of these currents has been to carry light particles of trash and motes to the center line of the perforated drum 31 of the condenser and the trash'would therefore be collected at that point and deposited on the drum, thus forming a streak down the center of the material wound on the drum, which was of much lower grade than the balance of the material on the drum. It had the appearance of a dirty streak which detracted very much fro'l th: value of the roll of material. I have discovered that by the use of my arrangement above described the deflection of a portion of the air down against the bottom wall will distribute the material evenly over the drum not only in thickness but in character and that there will not be any material collection of trash and motes at any particular point, as distinguished from any other point. In other words, he invention produces a product on the condenser of uniform quality throughout and thereby makes that product more valuable. The lint is of the same quality from one end of the condensing drum to the other.

Having thus described. the invention,

what is claimed and desiredto be secured by Letters Patent is:

1. In a device of the classdescribed, the combination with a cotton seed linter having an outlet for air carrying lint, of a condenser, a flue connecting said outlet with said condenser, and means at the entrance of said flue for causing a part of the air current entering said flue to strike against the inside bottom wall of said'flue thus preventing particles of lint from collecting on the bottom of the flue.

In a device of the class described, the combination with a cotton seed linter having an outlet for air carrying lint, of a condenser, a flue connecting said outlet with said condenser the parts being so arranged.

and proportioned as to cause a part of the air current entering said flue to move downward against the inside bottom wall of said flue thus presenting particles of lint from collecting on the bottom of the flue.

8. In a device of the class described, the combination with a cotton seed linter having an outlet for air carrying lint, of means for causing said air and lint to reach said outlet whentraveling upwardly at an angle, a condenser, a flue connecting said. outlet with said condenser, the bottom wall of said flue being more nearly horizontal than the line of travel of the entering air, and means at the entrance of said flue to deflect a portion of said air current down againstthe inside bottom wall of the fine to prevent the collection of lint at that point.

I. In a device of the class described, the combination with a' cotton seed. linter having a. narrow outlet for air carrying lint 8X? tending across said linter, of means for causing the air and lint to approach said outlet when traveling upward at a considerable angle, a condenser, a flue connecting said outlet with said condenser having side walls inwardly inclined toward each other and top and bottom walls outwardly inclined from each other, and means at the entrance of said. flue for deflecting a portion of said air down against the inside bottom wall of said flue to prevent the collection of lint at that point.

5. In a device of the class described, the combination with a cotton seed linter having a narrow outlet for air carrying lint extending across said linter, of means for causing the air and lint to approach said outlet when traveling upward at a considerable angle, a condenser, a flue connecting said outlet with said condenser having side walls inwardly inclined toward each other and top and bottom walls outwardly inclined from each other, and means at the entrance of said flue for so deflecting a portion of the entering air as to evenly and uniformly distribute the lint over the surface of the condenser druni forming a uniform-product.

In testimony whereof I al'fi): my signature in presence of two witnesses.
