SBEGIFICATION formingpart of Letters Patent No. 674,671, dated May 21, 1901. Application filed February 18, 1901. serial No. 47,837. (No model.)

To all whom it may concern:

.Be it known that I, JOSEPH E. OooMBs, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Hot-Water and Steam Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a hot-water or steam heater in which the main portions of the heater are made integral and at one casting, the object of the invention being to provide a cheap, practically jointless, but effective apparatus.

The invention will now be described in connection with the drawings.

Figure 1 is a view in vertical central section of a hot-water heater having the features of myinvention. Fig. 2 is a view in horizontal section upon the dotted line 2 2 of Fig. 1 and in plan of parts below said line. Fig. 3 is a view in horizontal section upon the dotted line 3 3 of Fig. 1. Fig. 4 is a view in elevation of a portion of the upper part of the heater, a casing or shell forming the smoke passage or fine being removed. Fig. 5 is a view principally in elevation of the heater when arranged as a steam-heater, a portion of the casing being broken out to show the modification in construction. I

Referring to the drawings, A represents the main portion ofthe'heater. It has the firepot space a, combustion-chamber a, lines a a and a water-chamber B, in two sections, one of which, the section b, incloses the ashpit and combustion-chamber from the bottom to the top of the shell or casting which forms the heater, and the other of which, the section b, is contained in the upper part of the combustion chamber and is dome or bell shaped and connected at its side and at its top with the outer section. The two sections 1) b of the water-chamber are formed by the walls I) b b and b the walls 12 b forming the outer section b of the water-chamber and the casing of the fire-pot and combustionchamber and the walls 19 19 forming the interior section b of the water-chamber. The two sections 1) b are united by means of the top into the chamber of the dome.

passage b at the lower end of the section Z) and upon its back side, and the passage b at the upper end of the chamber and the connections between the walls b forming these passages are integral with the walls.

The interior chamber is so shaped and disposed in the combustion-chamber as to form an upward extension a of the combustionchamber, from which extend the lines a and the surrounding extension (1 of the combustion-chamber, into which the lines a open and from which extend through the outer chamber-Z) the flues a to a cylindrical chamber or fine C66. The walls of these flues a a are integral with the walls of the two sections of the water-chamber. The bell or dome b may have a connection or chamber 19 extending across the cavity or section of the combustion chamber it contains, the walls of which are integral with the inner wall of the dome.

The dome is represented as having a single connection 19 with the outer chamber 1). It may have two or more, if desired.

The flue or chamber a is formed by a circular shell 0 of a size to fit upon the top of the outer wall b The lower edge 0 of this shell rests upon a shoulder c on said outer wall 19 and the edge or section 0 about its upper opening 0 rests upon the ledge or surface 0 at the top of the wall b surrounding the collar 0 This collar incloses the outlet B of the water-chamber. The water inlet or inlets are at B The shell 0 also has the seat 0 for the flange d of the coupling D, which connects the heater with the service pipe or pipes. The coupling in the drawings is represented as forked to provide a connection with the two service-pipes. The coupling, shell, and heater are bolted or riveted together by the bolts or rivets cl, which pass through the flange of the coupling, the shell, and the seat of the heater around the outletopening, these fasteners serving to unite the three parts together. The shell 0 has a smokeescape port 0 and a clean -out opening 0 which is closed by a door 0 (See Fig. 2.)

It will be understood that the products of combustion pass from the lower part of the combustion-chamber both into its extension The chamber opens at its ends and r all a Within the bell or dome and also into its extension a about the bell or dome and that from the extension Within the bell they pass by the fines a to the top part of the outer extension a where they unite with the products of combustion passing by the outer section to the fines a opening into the passage or fine a common to them all.

This construction provides a large area of heating-surface to the products of combustion Which is entirely jointless, and provides for a quick unretarded circulation of the water and for its disposition in relatively thin volume to the heating-surfaces.

It will be seen that the structure has no joints in its main portion, the only joints in the organization being where the water-supply pipe and the outlet-pipe make connection with the shell.

In Fig. 5 the structure is modified to provide a steam-dome, and in lieu of the shell 0 there is then employed a shell which I have lettered E and which includes not only a flue the equivalent of the fine a, but a steamchamber c. This chamber is connected with the water-chamber Bin the same manner that the coupling D is connected with it, and it has at its upper end a seat 6 for the flange of a steam service-pipe 6 The chamber 6 is connected with the water-inlet by a circulating-passage e inthe connecting-pipe e. The shell also has a lateral extension 6 for providing supports for a Water-gage, and it is further provided with means for the attachment of a safety-valve and a damper-regulator. I

Having thus fully described my invention, 1 claim and desire to secure by-Letters Patent of the United States 1. A jointless steam or hot-water heater, 4o

integral walls disposed to form a water-chamber surrounding a tire-pot, and combustionchamber and also a water-chamber inclosed in the combustion-chamber and the connections between the two chambers, the combustion-chamber extending on the inner and outer sides of said inclosed waterrchamber, and smoke-fines extending through the inclosed chamber and the outer chamber.

2. The combination in a steam or hot-Water heater of the integral casting consisting of the outer Wall 17 the inner Wall b the walls b', b united to the inner wall by integral connections forming the passages b b the firepot, combustion-chamber, combustion-chamber extensions and their dues with the shell 0 surrounding the upper part of this outer wall 13 and forming a common connecting smoke fine or passage for the due a 3. The combination in a steam or hot-water heater of the wall 19 having the seat 0', flues a and a seat about the outlet B with the shell 0 having an opening 0 an edge 0 about the opening to bear on said seat 0 and a lower edge 0 to bear against the seat 0.

4. The combination in a heater of the character specified of a wall having the shoulder c, fines a? and a seat about its outlet with a shell G having a flange to rest upon said seat,

an edge to bear against said shoulder and a seat for a coupling with a coupling having a flange to bear on said seat, the coupling, shell and Wall being united by fastenings common to the three parts.
