The annexed engravings are views of a machine for expelling the water from cloth, wool, and other fabrics by centrifugal action. The inventor is N. E. Chaffee, who received a patent for the same in 1848, and we published an engraving of his machine as then constructed, in No. 10, Vol. 4, Scientific American. Those of our readers who have that volume will perceive that the present engraving presents features in the machine which have made it operate in a superior mannerr and have rendered it more valuable. Figure 1 is a perspective view, and figure 2 is a transverse vertical section of the revolving wheel, which contains the wool or wet goods. A ig a frame or arc in which the wheel isplaced, and on the sides of which are the bearings of the shaft; B is the wheel. It is made like a dash wheel employed in calico and bleach works, only its periphery is made of wire rods as represented. It is divided in the middle by a partition or floor diametrically extending over the shaft. This separates the wheel inside into two chambers. Dyed cloth either woolen or cotton, or any kind of wet goods are placed in these chambers, and the wheel set in motion like a dash wheel. The particles of moisture, owing to their fluid nature, are thrown out of the goods by centrifugal action, and in a very short period they are rendered quite dry. There are a number of metal rods, figure 2, which extend from side to side, across the machine, over the shaft; they are arranged in the form of a small arch. They keep the goods off the partition, and air is admitted under them from the outsides through the central openings, C C . Figure 2 shows the said rods and the central openings. This arrangement is new and greatly facilitates the operation of drying. The goods, amp;c, are put in and taken out by doors in the sides, which are held fast by spring latches. The emptying and filling of these chambers are performed in the same way as those of the dash wheel; C is a cover to prevent the water from being thrown about outside. The rest of the machinery is for driving the wheel by differential pulleys, to give a fest and slow motion as may be required; M is the pulley from which a belt runs over a pulley on the wheel shaft, and drives the wheel. The cone pulley, G, receives motion by a belt, F, from cone pulley, E, which is driven by a belt from a water wheel or steam engine.mdash; The handle, D, is put on merely to show how motion is communicated ; H, I are two pulleys, the top one driving the lower one, Which is placed on the end of a screw-shaft J, on which is a travelling shipper K, that guides and directs the belt, F, to vary the velocity of the wheel. It is best to commence with the slow motion when the wheel is heavily loaded and gradually increase the speed, the shipper, K, guides the belt F, from the large to the small end of the cone pulley, G, thus gradually increasing the speed from the minimum to the maximum. The shipper is guided on the rod, L. This is a very excellent machine, and the different parts are well arranged. The screw, J, moves the shipper, K, to one side or other according as the screw is moved. This is done by throwing either of the two small belts on the double pulleys, H I, in and out of gear, by drawing out and pushing in the pul-ly I, which slides on a feather.
