UNTTED STATES PATENT OFFICE,

NEVELL P. ANDRUS, OF BROOKLYN, ASSIGNOR OF ONE-HALF TO ROBERT J. HAXBY, OF NEIV BRIGHTON, NEV YORK.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 410,529, dated September 3, 1889. Application filed June 19, 1889l Serial No. 314,881. (No model.)

To all whom it may concern:

Be lit known that I, NEWELL P. ANDRUs, a citizen of the United States, residing at Brooklyn, Kings county, State of New York, have invented a new and useful Improvementin \Vaterlleaters, of which the following is a specification, reference being' had to the accompanyin g drawings, forming a part thereof.

The object of my invention is to produce a water-heater of new construction wherein is secured increased heating-surface, a more general distribution of hot air around the water-chambers, and an improved system of water-circulation through the heater.

. \Vith these ends in view my invention consists in devices that are illustrated in the accompanying drawings, which will be hereinafter fully described and claimed.

In the drawings, Figure l is a .front elevation of the heater. Fig. 2 a vertical section of the same. Fig'. 3 is a plan of top of the fire-pot and seat of iirst section. Fig. et is a sectional plan taken on line .fr of Fig. l. Fig. 5 is an isometric sectional elevation of one circulating system. Fig. 6 is a part elevation showing position of ports, dac.; and Fig'. 7 is a part plan of one section, showing location of ports, tbc.

A represents a water-heater, in the lire-pot A of which is arranged a series of ports B, as shown. Each one of the ports B (ofthe series of ports arranged in the rim of the lire-pot A of the water-heater A) connects with awaterchamber C, (formed in the iirepot A above the grate and firebriek D, where combustion takes place,) and forms the basis of one of the circulating' systems of the heater, more particularly referred to and described hereinafter.

The heated water passing from the chamber C in the irepot A (up through the port B of its connections and system, as indicated by arrows) enters a water-chamber E, formed by walls F, above the door a and connecting-lip b, which chamber E is arranged in section l of the circulating system. In its upward tendency the heated water enters chamber E in section i2 of the circulating system through port B next above, which lastmentioned chamber and port are arranged at a suitable distance above and at the left-hand side of chamber E and port B of section l next below of the system, as shown in Fig. (i, and as are all the remaining chambers and ports of the system, hereinafter referred to, Fig. 5. The heated water enters chamber E2 of scction 3 of the system through port B2, and from thence the Water passes up throughport B3 and enters chamber Eithe uppermost one of the system in section 4 of the same. The water, having circulated through the several sections of the circulating system, as stated, passes a port B4, as indicated, and enters a water-receptacle E1 at the top of the heater for general distribution and to be returned to chamber C through return-pipes I to be reheated, ttc. The heat passes from the lirepot A of the heater upto and through flues R and S, which ilues are cast in sections and formed between the outsides of the walls F, which form the water-chambers E E E2 E3 of the water-circulatin g system hereinbefore de* scribed.

The fines el' the different sections are held in position in connect-ion with top T4 by bolts T', the said bolts connecting with lugs T2 in the re-pot A and lugs T on topTi, as shown.

The course of the hot air and gases from the hre-pot A', while the same are circulating through the fluesR S and spaces m under the bottom of chambers E E h2 of sections l 2 3 l of the water-circulating system, is indirect, and is obstructed by the arrangement of chambers, ports, and tlues, each one of which is above and out of a direct line with the other. This causes a deiiection of the heat in each section lo reach the port to enter the section next above, while the recesses,-

grooves, or niches t' in the bottom of the chambers retain a large proportion of the gases until the same are consumed, while the doors a of the sections are arranged to facilitate cleaning', dre.

One of the circulating' systems of the heater having been described herein, no further description is deemed necessary, as all the other circulating systems of theheater are identical with the one described above.

By my invention a large increase of heatingsurface With a more general distribution of heat around the chambers is secured, while the water-circulation is more perfect and com IDO plete in the heater than any of the circulating systems now in use.

Any practical number of circulating systems commensurate with the size of the heater may be employed therein.

What I claim is*- 1. In a Water-heater, the combination of a series of superposed chambers each provided with a series of irregular Waterpassages formed by their internal walls, said passages having separate inlets and outlets arranged equidistant around the chambers and having their respective consecutive Water-connections arranged spirally, and the heat-fines R and S, formed between the external Walls of said chambers and passing vertically through them, substantially as and for the purpose set forth.

NEIVELL P. ANDRUS.
