AIR CLWANSING AND COOLING DEVICE SPECIFICATION forming part of Letters Patent No. 626,388, dated J' une 6, 1899. Application filed November 5, 1897. Serial No. 657,528. (No model.)

To @ZZ whom it 71mg/ concern:

Be it known that I, JOSEPH MCGREERY, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio,

have invented certain new and useful Improvements in Air Cleansing and Cooling Devices; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in an air cleansing and cooling device; -and it consists in the construction hereinafter pointed out.

The special object of this invention is to construct a device in which not only is the water thoroughly commingled with the air and then the two separated, but also the device is kept from freezing when the temperature is low. V

In the drawings, Figure l represents an end view of the device, the outer part of the case being removed to show the interior construction. Fig'. 2 is a transverse vertical section through the case. Fig. 3 is a horizontal section taken through the bottoni ofthe case.

In the drawings the letter A represents an elongated case made preferably with an offset a and having its bottom a' preferably larger than the top portion a2. This case is provided with an air-inlet a3 at the top and an air-outlet d4 at the bottom. Near the top it has a water-inlet B and at the extreme bottom a water-outlet b. Attached to and depending from the nozzle b of the inlet B are two deiiectors O and C', one above the other and thelower the larger. Below these deflectors and extending transversely across the case A and spaced apart from one another are a number of staggered shallow pans D, which may or may not have at one side a lip CZ. These shallow pans D are placed in the upper part of the case A. Those of the pans D which are adjacent to that ,side of the offset a of the case which is the underneath side are secured by their adjacent edge to the side of such odset. The pans at the upper side of the offset are not so secured, but are spaced apart in the side of such offset. J ust below these pans and in the top of the bottom a are placed several transverse troughs E, such troughs being preferably made to hold more water than may be held in one of the pans D. These troughs E may be differentlyarranged. A little below the 1oWermost trough E and to each side a receptacle or trough F is located. An opening is left between the trough E and the receptacles F', as shown at G. J ust below the receptacles F and just above the outlet of* another receptacle II is placed to one side of the case A. An overflow-pipe K has branch pipes 7o,which comm unieate with the bottom of the troughs E E and receptacles F H. To the side of the case, away from the receptacle H and beyond its inner edge, is placed a trough I, from which depends a drain-pipe i, terminating near the bottom of the case. In the bottom ot' the case, extending from the under side of the receptacle H to the bottom of the case, and in front of the mouth of the outlet a4 are placed perpendicular separatonplates L, V- shaped in cross section and having their angles toward the outlet 0:1. At the extreme top of the case, above the water-inlet B, a steam-inlet M enters the case and has a downturned nozzle m.

Air and water enter the case at the top, the water falling by gravity and air under pressure in any of the well-known ways. As the water emerges from the nozzle b it is thrown,

about the case by the deflectors or spreaders. The water and air are th us com mingled at the top of the case. As they pass downwardly the water catches in the shallow pans D and runs over their edges. The offset ct and the side lips (Z of the pans D cause the Water to fall in spray toward the middle of the device. Both at the spreaders and in iowing over the edges of the pan the water is broken up into spray, so that the waterand air are thoroughly commingled as they pass down the case. By having the pans secured at their edges to the lunder side'of the offset water may not run down that side of the case, but is thrown toward the middle. It is unnecessary to secure the pans on the other side ofthe offset, as there is not any danger of the water striking that side of the case. When the water reaches the troughs E E and receptacles F, it passes off through the overflow-pipes 7c K. The air ICO 2 ceases passes down through the openings G, and any water which may pass down with the air is collected into the receptacle I-I or trough I. Should any Water fall to the bottom of the case, it will be caught by the separator-plates L.

It is obvious that a device like this will thoroughly commingle air and water, so that the former is effectually cleansed from all impurities.

At the same time the air and Water are both thoroughly separated, so that the air withut the water passes off through the outlet a When the temperature is low enough for freezing, steam may be admitted into the case through the inlet M. The steam passing down with the water and air effectually prevents any freezing in the case.

The case Ais made with an odset et, so that a device of less height may be used in a given space. In this class of devices, where baffleplates in the shape of alternating shelves are used, there is a sufficient length of passage, so that the air and water may be thoroughly commingled and also separated; but in some locations it is not feasible to use the device of such a construction, but a device of greater length and less width, such as a pipe, must be used. In such latter device in order to get the necessary flow a greater length of pipe is demanded than the space will sometimes allow. passage of the air and water, the offset a is made, this odset compensating for the shortening of the pipe in height. The length of pipe may remain the same, or in some instances if the offset be sufficiently marked the retardation of the water passing through the offset will compensate for diminution in the length of the pipe.

In order therefore to obtain the proper Having described the invention, what yI 4o claim is- 1. An air cleansing and cooling device, provided with the offset, a, having a water-inlet, an air-inlet, a Water-outlet and an air-outlet, a series of shallow pans secured in the upper part of the case and at the offset, those pans which are adjacent to the under side of the offset being secured thereto and the pans adjacent to the upper side of the offset ben ing spaced apart therefrom, and a series of 5o troughs, the pans and troughs being placed between the inlets and outlets and the troughs provided with overflow-pipes, as set forth.

2. An air cleansing and cooling device having Water and air inlets at the top and water and air outlets at the bottom, and between the inlets and outlets water pans and troughs, and below the troughs and'in front of the airoutlet a series of'perpendicular Veshaped separator-plates having'their angles toward the 6o air-outlet, as set forth.

3. An air cleansing and cooling device provided at its top with an air-inlet and a waterinlet, and at its bottom with an air-outlet and a water-outlet, and between the two with sev 65 eral shallow pans, several troughs provided with overflow-pipes, a water-receptacle provided with overiow pipes, a trough below such receptacle provided with drain-pi pes and perpendicular V-shaped separator-plates, as 7o set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH MOCREERY.
