SPECIFICATION forming part of Letters IPatent No. 423,653, dated March 18, 1890.

Application filed November 25, 1889- Serial No. 331,480' (No model.)

To all whom it may concern:

Be it known that I, MILTON ABRAMS, a citi-.

zen of the United States, residing at'Indianapolis, in the county of Marion and State of Indiana, have invented anew and useful Improvement in Feed-Tater Heaters and Puri fliers, of which the following is a specification.

My invention relates to an improvement in that class of devices for heating and purifying the Water supplied to steam-boilers in from the engine-cylinders by the exhauststeam from entering and commingling with the feed-water in the heater; and, second, to

more thoroughly and completely separate the magnesia and lime compounds and other 1111- purities from the feed-water, all as hereinafter. fully explained.

The accompanying drawings illustrate my invention.

Figure 1 represents a central vertical section of my device. Fig. 2 represents a plan at the line a, Fig. 1. Fig. 3 represents a section on the line b, Fig. 2, and below the line a, Fig. 1.

A is a cylindrical tank having a closed top, and formed, preferably, of boiler-iron. In the lower part of tank A is a horizontal annular partition B and a circular partition 0, which is riveted 'at the bottom to the tank and at the top to the inner edge of the annular partition B, thus forming a central well D. A portion of the annular space between the Walls of the tank and the circular partition 0 is separated from the rest by vertical partitions e and f, which rise above the horizontal partition B and join at the top, thus forming, with the front plate G, an inclosed chamber H. The exhaust-steam frointhe engine enters chamber H through the inlet-pipe I and passes out through the bent pipe J, so that it is discharged directly downward into the central well D. For the purpose of discharging from the exhaust-steam the oil and grease brought over from the engine and held in mechanical suspension the arrangement of the inlet-pipe I and discharge-pipe J is such that the central well and the Walls of the tank is divided by a series of vertical partitions land m into a series of communicating compartments a, the first of which communicates through an opening 0 in the partition C with the central well D. The arrangement of these 7 vertical partitions is such that there is a space over the top of the partitions Z, as seen indotted lines, Fig. 1, and a space under the partitions on, and they are arranged alternately so that Water passes from the top of the first compartment n and from the bottom of the next compartment, and so on to the lastcompartment from which the feed-Wat er is drawn through the pipe 19 for the supply of the boiler.

is an overflowi e arran ed in the last P P s of the compartments a. Each compartment is provided with a drain-pipe 7, closed by a suitable valve and a hand-hole s.

The upper part of the tank A is filled with a series of shallow panst and u, pans u having a central opening a. The pans are arranged alternately, so that the supply of water entering through thesupply-pipe W at the top of the tank overflows at the center of the first pan and at the edges of the next, and so on alternately until it falls onto the slightlyinclined annular partitionB and drains into the central Well D. y

Y is the escape-pipe, through which the uncondensed steam escapes.

'In operation water is pumped from the well or other source of supply through the supplypipe WV into the upper one of the series of pans, and from thence flows over the series of pans, as before explained, to the central well D. Exhaust-steam from the engine entering chamber II through pipe I is projected against the opposite wall of the chamber and 'drops in the chamber the grease and oil and a portion of the water carried therein, and

' thenpassing through bent pipe J is projected downward into the central well D, thus heating the water therein, and then passes upward, circulating around and between the pans t and u and heating the water contained in and overflowing. from the pans. A large portion of the steam is condensed and-flows downward with the feedwater, and the remainder passes off through the escape-pipe Y. The heated water from the wellD passes through the opening 0 to the first compartment n, and from thence over partitions Z and under partitions m successively until the last compartment is reached, from whence it is drawn out through the feed-water pipe 10. Those elementsin thewater-supply which ordinarily form the harder portions of the scale in the'boiler are deposited on the pans't and a, while the lighter magnesia and lime compounds contained therein, which in other heaters and purifiers is partially separated by passing the water through hay or other filtering material, is deposited as a sediment in the central well and the compartments n, in which the water stands comparatively still and under favorable conditions for the deposition'of chamber to the waterspace of the tank, all being arranged to co-operate substantially as specified, whereby the grease carried in suspension in the steam is precipitated before entering the water-space, as set forth.

2. In a feed-water heater, the combination of a water-tank, an inclosed chamber separated from the water-space thereof, a steam- ;supply pipe leading into said chamber from substances suspended in the steam are precipitated, substantially as set forth.

3. In a feed-water heater and purifier, the combination, with the water-tank, ot' the central well formed in the lower part of the tank, a series of compartments arranged around said well, one of which compartments coinmunicates with the well, and the compartments communicating with each other in succession at the top of one and at the bottom of the other, the steam-supply pipe arranged to enter the tank above the central well, thewater-supply pipe also arranged toenter the tank above said well, and the water-discharge pipe leading from the last compartment, all arranged to co-operate substantially as specified, whereby the water in the well is heated by the steam and is Withdrawn from the tank through a series of settling-compartments, substantially as specified.
