    Specification, A.D. 1859.—N° 2443. s Clark's Improvements in the Preparation and Application of Paths, §c. liquids employed, I will give a brief description of the one made use of in perfecting the apparatus, so that it may serve as a guide, and exemplify the practical nature of the Invention. It will be unnecessary to enter into any details as to the local or collective 5 peculiarities of the apparatus which comprise special arrangements of appa¬ ratus and the chambers or boxes, which must necessarily vary. In the apparatus herein-after described the subdivision of the water is effected by a current of air produced by a blower, pump, ventilator, or jet of steam. The air is heated, on its exit from the blowing apparatus, either by passing it 10 through a series of tubes placed in a furnace, or by causing it to circulate in a tube surrounded with hot water or steam, or in any suitable manner. It may also be exhausted in a heated space, which will be sufficient in certain cases. In the annexed Drawing, A represents a tube for conducting the forced current of heated air; B, air cylinder heated to a certain temperature, con- 15 taining the liquid to be used, about three quarts, which about half fills it; C, wheel, having small cups E, put in motion by any suitable means. These cups, in turning round, convey the water into a channel F, in front of a nozzle conveying a stream of air, which forces the water into the tube G, and effects its complete subdivision, when it escapes from the orifice II, and is distributed 20 in the bath box I. The size of orifice H should be in proportion to the quantity of liquid to be subdivided in a given time; in some cases it is about J of an inch in diameter. The dotted lines in the Drawing shows another form of bath box; the inclination given to the jet in the box may be varied, as desired. 25 Another method, which dispenses with the use of the cup wheel, consists in the employment of a wick of cotton which draws up into the reservoir the three quarts of water to be conducted into the tube almost drop by drop to the orifice of the nozzle of compressed air at its entrance to the box. In this manner the subdivision is effected in a very easy manner, which would be of 30 great service for certain descriptions of water or mixtures of liquids. When there are matters held in suspension in the water, it may be agitated by the force of a spring or weight. The wick above described may be replaced by two small capillary tubes, with orifices opposed the one to the other; the flow of water will be very slow, almost drop by drop, and may be regulated by 35 a level so as to furnish the exact quantity required. The liquid may be further supplied to the subdividing jet by means of a cock, which is regulated so as to supply any quantity at will; in all cases the reservoir containing the liquid for the bath should be arranged so as to be heated by a bath heater, or in any other manner. The cover of the box is supplied with points or pro<
