Abstract: 110,747. Taylor, C. Oct. 21, 1916, [Convention date]. Drying fabrics. - Fabrics in open form are dried in a casing in which a drying- medium, such as hot air, is circulated and which is provided w i t h a n endless travelling member furnished with rollers on which the fabric is hung in loops and conveyed through the casing, the rollers being rotated to move the fabrics vertically by their being provided with plain pinions running on fixed rails or spurpinions or worm-wheels in gear with endless travelling chains or a worm; a conveyer platform is provided for supporting the ends of the loops of fabric and conveying them through the casing. The apparatus is specially applicable for drying cotton, silk, or mixed cotton and silk fabrics passing directly from the dyeing-bowl and squeezing- rollers 38 of apparatus in which they have been dyed aniline black. The fabric m may pass round ordinary drying-cylinders 39 to the inlet 40 of a casing 1 which may be lined or covered with heat non-conducting material and have removable sections at the sides and top to permit access to the interior. Within the casing, the fabric passes to nip feeding-rollers 33 and is fed over one of a number of rollers 5 rotatably mounted on the links 7 of two parallel endless chains, which are moved in the direction of the arrow c by driven sprocketwheels 10, 11 and pass round idle wheels 20 at the bottom of the casing. The fabric passes freely over the roller 5 forming a loop until the movement of the chains brings the roller 5 against the rubber, felt, or other yielding surface of a roller 35, so that the fabric is nipped and the formation of a fresh loop on the other side of the roller 5 is commenced. The feed of the fabric is so regulated that an accumulation of material is formed at the foot of each loop, and this accumulation is supported by an endless conveyer-platform 22, which is moved in the direction of the arrows h at the same speed as the chains or at a lower speed, by driven rollers 23. The fabric leaves the casing at an outlet 41 and passes between deliveryrollers 42. Guide-walls 26, 27, which may be perforated, enclose the loops of fabric. Air at the desired temperature is forced by a blower 28 through pipes 30 and into pipes 31, which extend across the inside of the casing and are provided with slots &c. through which jets of air are delivered into contact with the fabric, the air leaving the casing by outlets 32 provided with dampers. In the apparatus shown, the ends of the rollers 5 are provided with friction rollers engaging fixed tracks so that the rollers 5 are rotated and cause a vertical movement of the fabric, but if it is desired that the rollers 5 should rotate at a greater speed than that caused by the motion of the chains carrying them, this may be effected by an independent chain and sprocket or worm and worm-wheel drive, the ends of the rollers 5 being supported by loose wheels thereon running on a fixed track: these loose wheels may have ball or roller bearings. The various parts are driven by bevel-wheel gearing &c. from a shaft driven by a belt &c. from a prime mover. The casing may be wide enough to accommodate two or more lengths of fabric side by side.
