Abstract: 19,508. Marr, A. N. Sept. 27. Drying yarns, fabrics, fibres, &c.-In apparatus for drying warps or hanks of yarn or other fibrous materials or fabrics, of the kind described in Specification No. 15,133, A.D. 1905, means are provided for carrying the material in festoons through the drying-chamber. Upper and lower rods T, 2 are carried on horizontal bands S, 1, having projections 31, 32, and passing round sprocket-wheels R, 1<a>, and these rods are supported at their ends on angle-iron races U, U<1>, 3. The material, either itself forming a length 30 or enclosed in a long net 30, passes in festoons over and under the interior rows of rods. The continuous renewal of these festoons is effected by vertical chains 12, 13, at the feed and delivery ends, furnished with projections 33, 34, whereby the rods are carried from one of the horizontal chains S, 1 to the other. First, the chains 12, 13 carry a pair of rods to the upper chains S, so that the final festoon is unfolded and an initial festoon is formed by a free rod passing under the fresh moist material. Next, the upper chain moves forward, dropping the final carrying and free rods into the chains 13, 12. The chains then carry these rods downwards to the lower horizontal chain, forming an initial and releasing a final festoon. Finally, the lower chain moves forward, delivering two rods to the chains 12, 13. This continuous cycle of movements of the chains is effected by means of a pinion C, Fig. 2, gearing with perimetric teeth on an oblong rack B, and driven through bevelgearing from a pulley A ; the rack moves on rollers 36. Beneath the rack B is a plate I having longitudinal side flanges so that, when the pin C engaging the ends of the rack moves it laterally, the plate I is also moved ,laterally in the channel J, and a pin M on the longest arm of a triple lever K, working in a slot M<1> in the channel J and passing through the plate I, is also moved laterally. One of the shorter arms K<1> of the lever is connected by a rod N to a lever O fitted with a pawl engaging a ratchet P on the shaft Q, on which are fixed the wheels R. The other arm K<2> is connected by a rod V, lever W, and rod X to a lever Y with its ratchet-wheel Z on the same shaft with a pair of the wheels 1<a>. Thus, when the pin C engages either end of the rack B, one row of rods is forwarded while the other remains at rest. When the rack moves longitudinally, the motion is transmitted by chains 4, 4<x>, which engage sprocket-wheels 5, 14 and are connected together adjustably. The wheel 5 is on the same shaft with the wheels R at the feed end and with a pair of wheels 7, which, by endless chains 10, actuate wheels 8 on shafts 9. On the shafts S<1>, 9 are sprocket-wheels carrying the vertical chains 12. The wheel 14 is on the same shaft as the wheels 16, 16<a> carrying the vertical chains 13. At the lower part of the feed end is a vertical chain driven from the shaft of its lower wheel through a wheel 27 and a wheel 26 co-axial with a pair of the wheels 1<a>. This chain has projections 24 and moves the rods 2 upwards past pivoted pawls 28, which afterwards fall into position for receiving and guiding rods carried down from the upper chain. The dried material may be delivered at either end and may be folded on brackets 42.
