' resin-WATER HEATER AND FILTER.

, The Schedule referred to in these Letters Patent 'and making part oithe same tion thereof, reference being bad to the accompanying drawing making part of this specification, in which- Figure 1 is a perspective view of the improved. apparatus.

Figure 2 is a section through the center of the apparatus in a verticalplane,

Figure 3 is a top view, showing the-construction of the sectional shelves.

Similar letters ofi reference indicate corresponding parts in the several figures.

The object of my invention is to so construct and combine an outside filteringchamber with a feedwater heater and purifierQthat the heavierparticles of floating mud or-sedinient of very muddy water shall be trapped below the filtering material, and the water, thus partially deprived of its dirt and extraneous substances, shall be passed upward through the filter and dischargedat apoint above the filtering material.

' In the schedule annexed to my reissued Letters Patent numbered 3,6l8, is described a feed-waterheater and purifier having filtering material arrangedwithin its casing beneath'a series of shelves, over which the water flows before passing through said iii-- tering material. a

In the schedule annexed to my Letters Patent,

numbered 93,244, is described a feed-water heater and purifier having a filtering-chamber arranged within its case below the series of shelves therein, in

such manner that the water is filtered by n'sing through this chamber from beneath it. 7

Where water is very muddy a'large amount of sediment, will be deposited in the case of the heater, and, if not frequently removed,--will clog up the pores of thefiltering-rnaterial and impair or totallydestroy its usefulness.

To obtain access to the filtering-material,when arranged as abovestated, within the case of the appa-. .ratus, it is necessary; to remove all 'theishelves below "the man-hole door, which is inconvenient and involves labor and loss of time.

Another object, is to arrangewithin the case of a feed-waterheater aseries of shelves, composed of sections having spaces between'them,the spaces of one series being arrangedover the shelves of the next lower series, whereby the water is distributed in thin sheets over a large extent of "snrfacein a comparatively smallspace, as will be hereinafter explained.

Toenable others skilled in the art to understand eration.

my invention, I will describe its construction and op- In the accompanying drawing-- A represents the outer shell of the heating and depositing apparatus, which shell is preferably made cylindrical, although it may be made rectangular or of any other shape.

W'ithin the shell or-case A are arranged in horizontal planes, a number of shelves, 1b, which are support-ed collectively upon a'rin'g, mfarranged a short distance above the bottom of the said case, as shown in fig. 2. V v The shelves have flanges secured to them, which support them in properposition, and which also space them, as shown in figs. 2 and 3. i Fig. 3 shows one series of shelves arranged as they would appear within the heater case, with .narrow spaces between them, and

Fig. ,2 shows the relative arrangement of the spaces between the shelves or plates h of one series or plane of shelveswith respect to the adjacent series or plane of shelves. 1

It will be seen that the space between two shelves h h, of one series, is directly over the eenterof the shelf of the succeeding series below.

By this arrangement, .the water, which enters the case at 0, will flow over the shelves in a great number of divided sheets, and-be dashed into spray and heated by the steam entering at g g.

'llie shelves It can be removed from the case A through-manholes by removing the covers a a of these holes.

An overflow-cup and a' spreader, or a cup-alone, may be applied to the inner end of the water-inlet pipe 0, as described in Letters Patent previously granted to me.

Beneath the lower shelves of the series is a chamber, J, to the bottom of which a pipe, closed by a cock, may be applied, for drawing ofi any deposition the chest B also means for obtaining access to the filtering material.

The filtering material may be confined in a wire- ;gauze box, fitted into the chest B, as shown in fig. 2, or any other. arrangement of this material may be adopted.

purifier, of the outside filtering device B, constructed with a mud-trap below, and with avwater-discharging pipe above the filtering material, substentially in the manner and for the purpose descn'bed.

2. The construction shown and described of the shelves h h within the case A, for the purpose set orth.
