' WATER HEATER.

Application filed June 21,

My invention pertains to water-heaters in association with furnaces or boilers, and aims to provide a simple and efficient-structure which may or may not be used, as desired, and without in any way interfering with the usual and proper functions of such furnace or boiler.

A. further purpose of the invention is the production of a structure of this character wherein the water tubes for the heater may be cleaned with facility and dispatch, and without disturbing other material or substantial parts of the appliance. To enable those skilled in this art to have a full and complete understanding of this invention, both from structural and func- ,tional standpoints, in the accompanying drawings, forming a part of this specification and throughout the several views of which like reference characters have been employed to designate the same parts, a present desirable and preferred embodiment of the invention has been illustrated.

In these drawings,

Figure 1 isa front or side elevation of the improved structure with parts broken away to more clearly show the internal construction;

Figure 2 is an end elevation of the appliance with some members shown in section;

Figure 3 is an enlarged fragmentary view of a part of the appliance showing one of the detachable connectors for operably joining together the ends of adjacent pipes or tubes; and

Figure 4 is a vertical section on line H of Figure 3.

Referring to these drawings, it will be perceived that the boiler has an outer, sheetmetal shell 11 and a corresponding inner, sheet-metal wall 12 spaced inwardly away therefrom asuitable distance to provide side and end water-legs 13 and 14, and the top:

1926. Serial No. 117,445.

Similarly an upper baflie-wall 19 rests on the topmost row of such pipes or tubes extending fully to the right-hand vertical wall of the boiler, but having a corresponding gap or passage 21 at the left-hand portion ;of the structure, whereby the heated gases their interiors being in communication and hence providing for the proper and eflicient flow of the water therein, such wall 22 dividmg that-portion of the boiler into two chambers, one of which'is equipped with any approved form of liquid or gaseous fuel-burner 23, while the other is fitted with a grate 24: and suitable doors 25, 26 and 27, in the front or side wall associated therewith.

'fhlS grate may be used to burn fuel on. or it may be employed for the drying and mclneration of garbage or the like.

At one end the furnace or boiler is fitted wlth a connection 28 adapted to be joined .in the usual way with a stack or chimney for the discharge of the gases.

As will be-readily understood, the eflicient and satisfactory oil or gas burner 23 has the grate 24 adjacent to it and which may be used to support the garbage or' other refuse while it is being dried out by the heat generated at such contiguous ,or adjoining burner and on which it may be consumed after it has been sufficiently freed fronr moisture in this manner.

Such grate may, at times, if desired, be employed for the burning of coal, coke, wood or other fuel, to supplement or augment the heating-action of the adjacent fluid-burner, or as a substitute therefor if required.

If preferred, the liquid or gas fuelburner, may be of such capacity as to provide adequate heat under all circumstances, or it may be of'lesser size or power and supplemented in its'heating function under extreme or unusual conditions, as by weather of very low temperature, by the combustion of fuel on the nearby auxiliary grate, where- .by the heating surfaces of the appliance under such circumstances are subjected to the joint action of both heating means. Or,

'if wanted, as for instance, if it were temporarily impossible to secure fuel for the fluid burner, the grate may be used alone for sustaining the solid fuel undergoing combustion.

The two heating means are so located and the baffle-walls are so arranged that substan tially the entire heating surfaces of the ap pliance are subjected to the action of the L ends of these heat generated by each.

So far as this portion of the structure is concerned, it is aimed to provide a construction which is simple in character, which operates efficiently, and which needs little attention, which is unlikely to become injured or damaged in ordinary service, and which may "be manufacturedeconomically.

5 The water-heater associated. with this boiler or furnace comprises a plurality of horizontal water-pipes 3131, located in the water space or water jacket in the divisionwall 22, and extended through the waterspaces in the side legs of the boiler, and their metal walls, such pipes being expanded. in the usual way to fit their holes in the inner and outer casings in fluid-tight manner.

Hence the water in these pipes has no direct connection with that in the legs of the' 1furnace, or that in the cross divisionwal The water to be heated, as distinguished from that in the boiler, is admitted to these pipes through a suitable manifold 32, secured against the outer face of the boiler in liquid-tight manner, in any approved way, and the water is fed into such manifold through an admission or inlet pipe 33 preferably equipped with a control valve 34.

At the opposite end of the boiler, the other pipes are connected together in like paralle relation by a manifold 35,

and hence, -it will be seen that these pipes,

j three in number, in the present instance, are

connected together in multiple.

A series or horizontal ro.w' of water-pipes "36 extend through the water in the lower portion of the top space 15 of the boiler, and

through apertures in its sheet-metal endwalls, being expanded. or enlarged in the.

latter to form tight fits, as is customary.

These pipes are joined together inseries relation, rather than in parallel or multiple manner, and, to this end, the manifold 35 is connected by a pipe 37 to a connection 38 bolted against the outer face or wall of the boiler, with a suitably interposed gasket, in register with one end of the outermost pipe of the series, by means of stud bolts 39 b0 ted in the metal wall and accommodated in apertures of lugs 41 outstanding from the. connection, nuts being used on such studs,

by a hollow fitting 42 similar to that desig-' nated 38, but large enough to cover the ends of two adjoining pipes.

By means of such fittings which are held in place by similar studs and nuts with intervening gaskets, all of these upper pipes are joined together in series or serpentine relation, and the last pipe thereof is connected in similar manner to a discharge pipe 43 by means of which the hot Water is conveyed to the place where it is to be used.

Thus the water entering through the pipe 33 leaves by means of pipe 43, having been suitably heated during its traverse through the pipe connections in the lower and upper portions of the boiler and all of which are immersed in and surrounded by difierent portions of the main body of water in such boiler.

This piping arrangement for the hot water provides means for the quick distribu- One advantage of this construction resides in the fact, that, if such hot water-heater is not desired to be laced in service, thenthe pipes 31 and 36 forming parts thereof and originally installed in the boiler when manufactured, are not connected up for use and no harm results.

Furthermore, all of these hot water-heater pipes or tubes are readily accessible for.

cleaning by merely removing the exterior manifolds or connections which give easy access to the full lengths of all of the pipes,

vsuch members being readily removable and replaceable, as will be understood.

This invention is not limited and restricted to the precise and exact details of structure illustrated and described and may be incorporated in physical form in several different ways, allinvolving the principles of the in vention or stated otherwise, many mechanical changes ma be made in the structure set' forth without eparture' from the heart and essence of the invention, and without the sacrifice of any of its material benefits and advantages.

I claim: 1. The combination of a boiler having I outer walls and adapted to containa body of water, said boiler in its lower portion having two combustion chambers separated from one another-by a hollow wall ada ted to contain water, a lower pipe exten ed through the water of said hollow wall, upper pes extended through said first mentioned body of water and through the opposite walls of the boiler, means outside of said walls connecting said upper pipes together, means connectm said lower pipe to said upper pipes, an means to feed water to said lower 1,es1,5sa

pipe, whereby the water may be heated in flowing through said lower pipe and upper pipes.

2. The combination of a boiler having outer walls and adapted to contain a body of water, said boiler in its lower portion having two combustion chambers separated from one another by a hollow wall adapted to contain water, a plurality of lower pipes connected together in multiplerelation and extended through the water of said hollow wall, upper pipes extended through said first mentioned body of water and through the opposite walls of the boiler, means outside of said walls connecting said upper pipes together in series relation, means connecting said lower pipes to said upper pipes, and means to feed water to saidilower pipes, whereby the water may be heated in flowing through said lower and upper pipes.

In witness whereof I have hereunto set my hand.
