Mr. S. E. Worrell, of Hanni-bal, Mo., has built and intro-duced a successful drying ma-chine, which is illustratedherewith. Fig. 3 is a per-spective view of the largestsize machine. No. 4, having acapacity for handling 10,000pounds of washed coffee perday of twenty-four hours, in which the drying cylinder is six feet in diameter byflfteen feet long. Two smaller sizes are made of acapacity of 5,000 and 3,500 pounds each per day. Therotating cylinder. A, as shown in the sectional 1 and 3, is made of steel plate, covered by a woodjacket to save heat and equalize the temperature, andhas at each end a heavy iron rim, supported and ro-tated by two chilled iron flanged rollers, carried onshort steel shafts, journaled in inclined selfoiling boxes. THE AEROPHILE. 1. Apparatus closed. 2. Apparatus open. bolted to iron bed plates resting on timber blocks andstone foundations. Motion is transmitted to the cylin-der through the taper drum pulley, spur gearing,sprocket wheels and chain belt, from a countershaftoverhead. To the inside of the cylinder are attached aseries of segmental pockets, I, as shown in Figs. 1 and3, of galvanized steel plate, the inner sides of which aregridironed with numerous traverse slots, i, for droppingthe washed coffee in the falling streams, J. In rotatingcylinder driers as heretofore constructed these streamshave extended longitudinally through the dryingchamber, which permits a portion of the hot air toescape without doing its duty—a waste which is savedin these machines. In operation a charge of 5,000 pounds of washedcoffee is introduced into the stationary drying cylinderfrom the floor above, by movable spouts, through the five upper doors,
