METHOD 0F PRODUClNG A COOL ATMOSPHERE IN ROOMS AND APARTMENTS.

SPECIFICATION forming part of. Letters Patent No. 272,653, dated February 20, 1883.

Application filed October 24, 1881.

To all whom it may concern:

Be it known that I, HENRY D. COGSWELL, ot the city and county ot' San Francisco, inthe b'tate of California, havedevised and invented a' new and useful Method of and Apparatus for Cooling Atmosphere in Rooms and Apartments; and I do hereby declare that the following is a full, clear, and exact description ot' the same, reference being had to the accompanying drawings.

My'inveution relates to a means ot'prodncing and maintaining a low degree of temperature or cool condition ot' the atn'iosphere ot' rooms and apartments during seasons of heat. Itis more especially applicable to sick-rooms, wards of hospitals, tenements, and like situations to reduce the heat therein during hot weather.

I form a wall or partition ot' a number' of hollow panels made of uuglazed earthenware or pottery, the hollow spaces ot' which are connected together by suitable tubes or inlet and outlet apertures, and in causing a stream or body ot' water to pass through and circulate within these hollow panels by making connection with them of a water-supply pipe, whereby the immediate atmosphere wherein the wall or partition ot' panels is set up has its temperature reduced by the percolation of the water through the panels and its evaporation on the outside, while the circulation of the water through the series ot' panels also acts to take up and carry ott' heat from the air in contact with such surt'aces.

Referring to the accompanying drawings, Figure 1 shows the application ot' my invention to the sides ot' an apartment. Fig. 2 shows a horizontal section through the coolingsurfaces orpartitions as arranged around three sides ot'an apartment. Fig. 3 is adetail view, showing the manner of coupling two hollow panels together. Fig. 4 shows the application to the ward of a hospital or similar situation. Fig. 5 shows the manner of securing and holding the panels in line and position by means ot the horizontal pipe or bar ot' a supporting frame-work.

A may represent any room or place to be cooled.

B are the cooling-surfaces, which I apply and set up around the sides of the room, subst-antially in thefollowing manner: I first form hollow panels c c of porous earthenware or pot- (No model.)

tery of the desired height to which I propose to carry the surt'ace B, and ot' suitable thickness to give a hollow space or chamber, d, and to be sufficiently strong to resist breakage in handling and setting up. Into and lrom this hollow space 1,1 provide inlet and outlet openings ef in such position or relation tliat when ltwo panels are set together edge to edge the outlet of one panel shall coincide with the inlet of the next one, and communication is had between the two spam s l d. A simple construction of these panels is shown in Figs. 2 and 3 of the drawings, where several panels joined together are seen in horizontal section. A projecting nipple or short tube, c, is t'ormed around the aperlure'at oneI edge ot' the panel,

of a size and length to lit into and be received by a recess or socket around the aperturef in the adjacent edge ot' thenextpauel. Suitable packing, lz, can be placed iu this socket, and

when the two panels are set together a. close joint will be produced at the apertures that connect one space d with another. will then be formed with a. tube at one side or edge and a socket on the oppositeside, so that the panels may be employed in any required number and will be interchangeable. l prefer to place one ot' these apertures at the top and the other at the bottom of the panel, so that the circulation of the water through the hollow spaces d shall take place regularly from top to bottom of one andfrom bottom to top of the other, and so on throughout the series. These panels I set upright around one or more sides of the apartment or place to be cooled, or else in the form of a. partition, through the center thereof, or in a posit-ion at a distance lroin the wall so that both sides ofthe panels can be utilized for cooling-surfaces. At and along the bottom ot' this wall or partition I place a shallow trough 0r gutter, I, having connection with a wast-e pipe, J, for the purpose ot' catching the drippings from the outer surfaces of the panels and leading them away. Short legs or projections can be formed on the bottoni edge ofthe panels to raise them slightly above the surface ofthe trough and allow the water to run olii' from beneath them. The trough I should have a slight pitch or inclination toward the point of discharge. 'lo hold this partition or set of panels in the required upright position, I make use of small angle- Each panel IOO plates K, which I secure to the walls of the apartment so that the edge of the plate projects over the top of the panel; or when the panels are set out clear of a wall or othersurface where such fastening could not be employed I make the panel with a shallow groove, Z, along its top or upper edge, in which I lay a top rail or bar, M, having suitable upright supports or standards secured at intervals to the door, so as to form a light frame-work to keep the "panels in proper position. This rail M may form the water-supplypipe tolead water to the panels, as shown in Fig. 4, in'which case short tubes or nipples m will project from the pipe M into the hollowspaces d cl. At these points suitablestop valves or cocks, N, can be placed to regulate the supply of water to any number or set of panels. In this construction, when additional cooling effect or action might be desirable, the pipes M can be perforated or pierced atintervals with minute punctures an, so that a number of nejets or streams of water can be applied to the outside surface of the panels and allowed to ow down to the bottom, where any excess left after evaporation on the surface will be caught in the trough I. The last panel in any set or number set up to give an evaporatingand cooling` surfaceis connected with a waste-pipe, P, so that the water can circulate through the several hollow spaces d d with greater or less rapidity, according to .the size of the inlet and discharge openings caused to be taken up and absorbed bythe pores of this surface in suflcient quantity to pass through and evaporate on the outer side orisurface presented to the atmosphere to be cooled.

Having thus fully described my invention, what I claim, and desire to secure' by Letters Patent, is-

1. A cooling-wall for use in rooms, formed of hollow panels of earthenware constructed in separate pieces or parts and built together in a continuous wall, having inlet and outlet pipes connecting the several pieces, the whole. being mounted in a receiving-trough, I, and provided with a water supply and exit, substantially as set forth.

2. A wall, partition, or upright surface constructed of separately-formed hollow panels of 6c let-opening, c, adapted to fit in the openingf 7o of a companion brick, substantially as set forth.

et. In combination with the set or number of upright panels c, having spaces d d and inlet and outlet apertures ef, for connecting one space with another, as described, the water- -supply pipe M, having dlstributing tubes o1' nozzles N, and forming the means of supportving the said panels in line and position, substantially in the manner set forth..
