APPARATUS FOR PURlFYlNG THE-WATER FROM CONDENSERS.

SPECIFICATION forming part of Letters Patent No. 255,086, dated March 14, 1882.

Application filed December 13, 1881. (No model.)

To all whom it may concern Be it known that I, JoHN B. REDMOND, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Apparatus for Purifying the Water from Condensers, of which the fol-' lowing is a specification, reference being had therein to the accompanying drawings.

The objectof my invention is to provide a water-purifier for steam-boilers, which shall be adapted to separate all grease or oil from the water, thereby preventing such matter from passing to and through the feed pump and thence to the boiler.

It is well known that the water from surfacecondensers contains oil, and that where such water is employed as feed-water for the boiler the oil also enters the boiler, and by coating theinterior of the boiler frequently is the cause of the burning of the boiler.

Inventions of this class are designed to separate the oil or grease from the water, and the presentinvention is so constructed as to effectually serve this purpose and at all times to afford ready access to the accumulation of separated oil-or grease in order to remove the same.

In the drawings hereto annexed, Figure 1 is 0 a perspective sectional view of the apparatus.

Fig. 2 is a plan'view of the apparatus.

The letter Aon the drawings designates the casing of the apparatus. It may be made of wood or very thin iron, and its longest dimension is in a horizontal direction. At one end is a compartment, B,into the top of which fits a detachable strainer-box, 0, having a flange by which it is supported. strainer-box project above the case. The hot- 0 tom of this strainer-box is perforated to allow the water to pass, and in practice some suitable packing material is employed-such as sh avings-which is placed in the box upon the perforated bottom,-and the water from the condenser-pipe or exhaustD has to filter through the packing material, the latter servin g mainly to break the force of the falling water.

Below the wall 6, which formsone side of the first compartment, is an opening,f, which The sides of'"the leadstotheadjoiningcompartment,Gt. Across the center of the bottom of this latter compartment is a dam, h, about one half or less than onehalf the height of the side walls of the case A. The water first enters compartment Gr through the opening f, then rises therein until it overflows the darn h, and thence passes from this compartment through the opening f below the wall e on the opposite side. In like manner the water passes through compartment G, which is also provided with a dam, h,

the same as before described. On the opposite side of the dam h is a perforated diaphragm or horizontal partition, t, which forms the topside of a filtering chamber, J, which is filled with some suitable filtering material, preferably charcoal in small lumps. It will be seen the dam h is higher than or extends above the surface of the horizontal perforated side of the filter-box. An opening, 70, below the wall e allows the water to pass from the filterbox to the receiver L, from whence the water, which upon its arrival here has been deprived of all grease, is pumped to the boiler.

The receiver for the purified water has an exit-pipe, m, which leads to the feedpump, and an adjustable draw-off or overflow pipe. This overflow consists of a goose-neck pipe, 11., one end of which is secured to and upon the outer side of the easin g, and should either pass through the wall of the casing or connect with .a suitable opening entering through the wall into the receiver-chamber L. The connection of the end of the goose-neck pipe to the side of the casing is such that it may have the positionshownin full lines in Fig. 1that is, perfectly upright-or may be turned down to the position indicated by broken lines, or may have any intermediate position. This overflow, by this arrangement of pivoting one end, is capable of any desired adjustment, and it will be 0 seen that by it the level or height of the waterline above the dams within the several compartments is regulated,and also by turning it entirely down it serves as a draw-off to empty the case.

The operation of the apparatus is as follows: The water containing the grease enters the compartment G. As the water must rise to flow the bottom, and as the grease will naturally float upon the surface of the water, it will be seen the efiect is to permit the water to pass from the compartment, after first allowing the grease to rise and float on the surface, and the grease is thereby retained in the compartment and accumulateson the surface of the water,

while the Water passes out below.

The accumulation of grease may bekeptfrom interfering with the operation of the apparatus by simply turning the pivoted goose-neck pipe a little, so as to raise the water-level in the case a little higher above the dams. As the perforated top 2' of the filter-box is below the edge of the dam h and below the water-level, the floating grease on the water surface, if any grease should find access to this last compartment, will not pass the perforations.

Thehorizontal position of the case, with the several compartments on the same level or plane, and with each compartment open or having a removable top, renders it easy to remove the accumulations of grease from the surface of the water at any time and without for a moment interfering with the operation of the apparatus.

Having described my invention, I claim and desire to secure by Letters Patentof the United States- 1. In an apparatus for separating grease from the water discharged from steam-engine condensers,a horizontal case divided by walls into compartments having the same level or plane, all the compartments connected by openings through the walls, and the said case provided at one end'with a pivoted dra w-ofi' or overflow pipe, 12, as shown and described.

2. .An apparatus for separating grease from the water discharged from steam-engine condenser-s, having at one end a detachable strainer-boX, G, at the opposite end and on the same level or plane a purified-water-receiving chamber, L, provided with a pivoted draw off or overflow pipe, a, and between the said ends one or more compartments provided with a dam across the center of its bottom and openings tor the passage of the water into and out of the compartment, as set forth.

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

JOHN B. REDMOND.
