CONDENSER FOR COTTON-GINS.

SPECIFICATION forming part of Letters Patent No. 462,404, dated November 3, 1891. Application filed March 12, 1891. Serial No. 384,746. (No model.)

To this endIcombine with ries with it in suspension the loose 'inned one or moreginsatrunk, into which the fiber is fiber or lint, which is deposited on tile surdischarged and through which it is carried by faces of the cylinders and by their revolution the air-blast produced by the gin-brushes to in the direction indicated bv the arrows 5 the condenser-cylinders.

The result of ately in advance of the cylindersfas shown the enlargement in this manner is to increase at a and in like manner curve the bottom the sectional area and diminish the velocity wall downward, as shown at a. The top and bottom walls terminate, as shown, substantially on a level with the axes of the respective cylinders, so that their surfaces are equally exposed to the advancing fiber. In practice I have found that this vertical enlargement of the mouth of the trunk by upward and downward curves is of great advantage in that it secures a uniformity of distribution and a freedom from clogging and other interruptions not attainable to the same extent by any other means of which I am aware.

I find it desirable to give the trunk opposite the end of each gin an increasing area longitudinally toward the condenser, or, in other words, from one side of thegin to the other, as shown in Fig. 2. This compensates for the increasing volume of air, maintains a uniform current, and insures the carrying forward of the fiber in a proper manner.

The best results as regards the continuity and regularity of the current and the uniformity of the distribution of the fibcr on the cylinders are attained when the trunk is made, as shown, of gradually-increasing depth from its beginning to a point beyond the last gin, and carried from the last gin upward to the condenser with a reverse curvature, as shown at b b. I also find it desirable to curve the fines or conductors throughwhich the gins deliver into the main trunk in the direction of the condenser, or, in other words, in the direction in which the fiber is to be conveyed, as plainly shown in Fig. 3. The existence of sudden constrictions 0r angular surfaces, which will produce reactionary currents and eddies and a consequentlodgment of the fiber, is to be particularly avoided.

Having thus described my invention, what I claim is 1. In combination with acotton-gin and a condenser having two pervio'us cylinders, one above the other, an intermediate trunk, through which the gin delivers the lint-cotton to the condenser, said trunk having its delivery end enlarged by an upward and'down ward curvature of its top and bottom walls, substantially as described, and as distinguished from an angular enlargement.

2. In combination with a cotton-gin and a condenser at a higher level, an intermediate trunk extending horizontally from the gin, then curved upward. and finally expanded vertically in curved lines at its delivery-end, substantially as and for the purposes described. V

3. In combination with a gin, a trunk for conducting the lint-cotton therefrom, pervious condensing-cylinders at the end of the trunk, and an inclosing case having openings for the delivery of the air from the interior of the cylinders at both ends, whereby the distribu tion of the fiber on the two ends of the cylinders is equalized.

4:. In combination with cotton-gins, a flue arranged to receive into its side the lint-carrying blasts from the gins, said flue having its portions opposite the gins tapered and widened vertically in the direction of its length, whereby the current in the fine is given a substantially constant velocity and adapted to maintain a uniform distribution of the moving fiber.

In testimony whereof I hereunto set my hand, this 6th day of March, 1891, in the presence of two attesting witnesses.
