APPARATUS FOR COOLING, WARMING, MOISTENlNG, OR SATURATING AIR.

SPECIFICATION forming part of Letters Patent No. 406,216, dated July 2, 1889. Application filed December 4:, 1888, Serial No. 292,661. (No model.) Patented in England March 5 1886, No. 3,134.

To all whom it may concern:

Be it known that I, JAMES I'IOWOR'IH, ventilator-manufact-urer, a subject of the Queen of Great Britain, residing at Farnworth, in the county of Lancaster, England, have invented certain Improvements in Apparatus for Cooling, arming, Moistening, or saturating Air, (for which I have obtained a patent in Great Britain, No. 3,134, dated 5th day of March, 1886,) of which the following is a specification.

My invention relates to apparatus for cooling, warming, moistening, or saturating air which is supplied to mills, weaving-sheds, factories, churches, schools, halls, dwellings, and buildings of all descriptions; and it consists in an improved arrangement or construction of such apparatus, by means of which any desired degree of temperature and humidity of the air can be obtained.

In order that my invention may be more readily understood and carried into practical effect, I have hereunto appended a sheet of drawings marked with letters of reference, similar letters denoting similar parts in'the different figures.

Figure 1 is a top view of the apparatus; Fig. 2, a longitudinal section of the same along the line X WV on Fig. 4 Fig. 3, a similar section along line Y Z on Fig. 4; Fig. 4, an endyiew from the left side, partly in section, along the line U V 011 Fig. 2; Fig. 5, an end view from the right side of the apparatus; Fig. (3, a longitudinal section similar to Fig. 3, showing an arrangement, hereinafter described, for supplying theapparatus with the water condensed in the heating-pipe.

The apparatus consists of a chamber, oasing, or chest A, hereinafter called the chest, constructed of galvanized sheet-iron or other metal,which is generally of rectangular shape, as shown on the drawings, but maybe of any other shape suitable for the locality or position in which it is to be placed in the building and for the reception of the fittings hereinafter described. lower part by a mid-feather or dividing-plate Zinto two compartments, one of which, hereinafter called the dry compartment, has

an inlet at or near the bottom for the air to enter the chest, as shown at C on Fig. 4. In

This chest is divided in its this compartment a serpentine or coiled pipe I), or its equivalent, is placed, having an inletpipe a, with a regulating valve or tap a at the top, and an outlet-pipe g, with a regulatingtap g at the bottom. The second compartment, hereinafter called the Wet compartment, is partly filled with Water 70 through a supply-pipe d with tap cl and fitted with an overflow-pipe e for waste Water. A pipe 0 passes through the water, and is fitted with a regulating valve or tap c and an outlet-pipe f with tap f. A hood or deflecting-plate 1' is fixed above the coil bin the dry compartment and extends over the dividing-plate nearly to the bottom of the wet compartment.

WVhen warm and moist air is required, the coil 12 and pipe 0 are supplied with steam through the taps a and 0, respectively, and

the waste steam and Water formed by condensation from the coil 1) are let out through thetap g and pipe g and from the pipe 0 through the tap f and pipe f. The air enters the dry compartment ator near the bottom, as shown at O on Fig. 4 and indicated by the arrow, and becoming heated by contact with and radiation from the coil b ascends to the top, where it is deflected by the deflectingplate t and made to impinge upon the water It in the wet compartment. The Water being heated by the steam in pipe 0 evolves vapor and the air mixes or becomes saturated with the vapor from the Water. It then ascends to the top of the casing or chamber and passes into the room through the diffusing-grid h, hereinafter described. The apparatus is generally placed against the outer walls of the room or building and the inlet at the-bottom prolonged to or placed in communication with the outside, and any ordinary or known kind of dust-strainer may be placed in the inlet and the air caused to flow in the direction hereinbefore described, and indicated by the arrows on Fig. 4, through being heated in the chest; or it may be drawn through it by ventilators or exhausters placed at the opposite side of the room or in the ceiling or by chimney-draft, or may be forced through it by fans or blowers.

By regulating the supply of steam and Water the temperature and humidity of the air can be regulated to any desired degree.

If dry warm air is required, the wet compartment is left without water, while the coil 1) and pipe 0 are supplied with steam. If the air is to be cooled, the steam is shut off, and instead thereof cold water or other refrigeratingliquid may be circulated in the pipes and the cold air may be delivered dry or moist, according as the wet compartment is filled with water or left empty. No matter what the condition of the air may be before entering the chest, it may be purified and rendered suitable for inhalation. In dry weather it may be moistened to anydegrce of humidity. In cold weather it maybe heated to any temperature, and in hot weather cooled to any required degree.

The air enters the room from the apparatus through the diffusing-grid 72., which may be placed on the top of the casing or chamber; or the latter may be closed at the top and have a lateral outlet fitted with the diffusing-grid, as maybe required by the position of the apparatus in the room or building. The diffusing-grid consists of a frame made, by prefer ence, of wood with wooden bars of triangular or trapeze-shaped section, placed with the broadest side toward the inside of the casing or chamber and parallel to each other, so that the air can pass between them, and entering at a narrow space becomes diffused througha wider space and passes into the room without perceptible draft.

A further improvement of the apparatus when used for supplying warm moist air is shown on Fig. 6, and consists in an arrangement for taking the waste steam and water formed by condensation from the pipe which heats the water in the wet compartment back into this compartment. This is effected by carrying the pipe 0 upward as it leaves the water-compartment, and making it in the form of a siphon with its bent end extending down into the water-compartment into which it discharges. By means of the regulatingt-ap f on this siphon-pipe and the tap c on the pipe 0 the pressure can be so regulated that the waste steam and water formed by condensation in the heating-pipe, instead of being carried away into a drain or collectingtank, are returned into the wet compartment and emptied into the water 70. By this means the compartment is continually supplied with water in small quantities for the purpose of generating vapor for saturating the air in the l1ereinbefore described manner. By this siphon arrangei'nent a saving is effected in the quantity of water used, and the pipes for carrying away the water formed by condensation may be dispensed with.

I claim An apparatus for cooling, heating, or moistening air, consisting of a box divided by a dividing-plate into two compartments at its lower part, the dry compartment having an air-inlet at the bottom and containing a coil of pipe for steam or refrigerating-liquid, and at the top a hood or deflecting-plate extending over the dividing-plate to deflect the air into the wet compartment, which latter contains a steanrpipe and stop-cocks for the pipes, as and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
