HEATER FOR WATER, 8&0.

SPECIFICATION forming part of Letters Patent No. 612,668, dated October 18, 1898.

Application filed March 1, 1897.

teammate. (NonmdeL) 1 1'0 0 46 whom it may concern.-

Be it known that I, ANTHONY J. LEwKo- WICZ, of Bayonne, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Heaters for Wato the heating of any fluid by the heat of any other circulating heating agent or medium.

I will first describe my invention in detail with reference to the accompanying drawings and will afterward point out its novelty in a claim. v t

Figure 1 represents a front elevation of a feed-water heater embodying my invention, having portions of the front pipes broken away to fully expose the heating-tubes and headers. Fig. 2 represents a transverse section in the line 2 2 of Fig. 1. Fig. 8 is in part a plan view and in part a horizontal section in the line 3 3 of Fig. 2. Fig. 4 represents a central longitudinal vertical section of part of the'lower header.

A and B designate, respectively, the upper and lower headers, which are hollow and constitute water-spaces, and a b the inner and outer tubes,whieh are arranged upright in one or more rows, two rows being represented, and are connected with the headers in any suitable lnanner, as by being expanded into holes therein in the manner common in multitubular structures. The outer tubes a are only long enough to just enter the headers; but the inner ones b are extended right through them, so that water introduced into the lower header by pipes c 0 may circulate upward in a thin film through the annular spaces between the outer and inner tubes and through the upper header and pass out from the latter through pipes at d, and the said film may be exposed, both outside through the outer tubes at and inside through the inner tubes 6, to any heating medium which may be caused to circulate around the outer tubes a and through the inner tubes 1).

The lower header may be of any length and width, according to the number of tubes in the rows and the number of rows, and of convenient depth. It consists of a single east ing or integral box, which may be without partitions, or may be divided transversely by partitions c, as shown in dotted outlines in Figs. 1 and 3, into any number of compartments, one for every two or more tubes, there being one such compartment for every four tubes, two of each row in the example represented. The upper header is sectional-that is to say, it consists of several sections or independent boxes ]3, arranged side by side without intercommunication, each receiving one or more of the tubes at b of each row. In the example represented each box or section takes in only two tubes-via, one of each row. The said boxes or sections are provided with flanges f, through which they are bolted together by bolts g, the holes provided in the said flanges for the said bolts being elongated, as shown at h in Fig. 2, or long enough in a vertical direction to provide for themovement of the boxes independently of each other in such manner as to permit the free longitudinal expansion and contraction of the tubes which enter each box independently of all the other tubes. Any displacement of the boxes relatively to each other produced by unequal expansion is prevented from becoming permanent by the integral structure of the lower box A, which holds the lower ends of the tubes to their normal position.

The lower header A has cast within it open passages 7s, (see Figs. 3 and 4,) the said passages running through it in the same direction as the tubes to provide for the free eirculation of the heating medium through said header and between the tubes a. The upper header has similar passages k, provided through it between its boxes or sections B by forming recesses in the sides of the said boxes, as shown in Fig. 3. The walls of said passages constitute heating-surfaces.

The inlet-pipes c c, of which there may be any suitable number, according to the length of the header A, are connected in angular form, as shown in Fig. 2, by means of sockets 'L', which project upward from a mud-drum O, and the upright pipes c are all connected with a common supply-pipe D, which is arranged horizontally and lengthwise of the rows of main heating-tubes a b and which receives the water through a pipe E from a feed-pump or other means of supply. The angular connection of the pipes c 0 provides for the expansion and contraction of the main heater-tubes a b, and the mud-drum 0, below the said angular connection, serves for the collection of impurities precipitated from the water.

The outlet-pipes d d, of which there is one for each box or section B of the upper header, are connected in angular form by means of elbows 61 thus providing for the expansion and contraction of the main heating-tubes a b. The pipes d are all connected with ahorizontal receiving-pipe F, which is arranged lengthwise of the rows of main heating-tubes a b and from which a pipe G leads to the steam-boiler or other apparatus to which the heated water is to be supplied.

The heater thus constructed may be arranged in the uptake of marine boilers above the tubes, or in the stack or in the flue, stack, or chimney of an ordinary stationary boiler, where the Waste gases of combustion may circulate around the headers and through the passages 70 therein, around and between the outer tubes at, through the inner tubes 1), and around the pipes D c c, drum 0, and pipes d d F. The said heater when applied to any steam-boiler will be connected up between the pump and the check-valve on the boiler, I

so that the heating of water to any degree of temperature will not affect the operation of the pump in any way.

The lower header A is represented as constructed (see Fig. 2) with a downwardly-projecting fiangej, surrounding its lower edge. This'flange may be of any suitable depth and flared outward in inverted-funnel shape, as shown at t in dotted outline in Fig. 3, to collect the gases and direct them into the inner main heating-tubes b.

What I claim as my invention is In a heater for water or other fluid, the combination of two hollow headers one of which is an integral box and the other of which is composed of a series of separate boxes, outer tubes forming communication between said headers, inner tubes running completely through both headers, and connections between said boxes whereby they are permitted to adapt themselves separately to unequal expansions of the tubes, substantially as herein described.
