'SPEGIFICATI QN forming part of Lettersfatent No; 633,897 dated September 26, 1899.

Application filed April 13, 1898.

To (LZZ 2 071.011? it may concern: Be it known that 1, WILLIAM H. PAGE, a citizen of the United States, residing at Norwich, New London county, Connecticut, have invented certain new and useful Improvements in Hot-Water Heaters, of which the following is'a full, clear, and exact description. 7 My invention relates to hot-water heaters, and particularly that class made up of a multiple of vertical sections, each of which is suitably'formed to provide water chambers and passages, all of said sections being so connected that free and rapid circulation of the water may be maintained. 7

My object is to improve the sections of this class of heaters and also to produce a duplex form of heater specially adapted for different temperatures. In. carrying this last-named feature of my invention into effect I provide in a single structure a heater'of small capacity for use in moderate weather, a somewhat larger heater for use in'colder' weather, and also a heater of. the combined capacity of the two already specified for use in extremely cold weather. These heaters differ in capacity, it being possible, as above stated, to operate the same independently or in unison, a great range of capacity for the complete device be-. ing thus made possible.

A further object of my invention is to provide a heater having not only the advantages above set forth, but also certain construction whereby the water is presented to thefire in a most advantageous manner, this last-named result being accomplished by means of the peculiar construction of the sections comprising the heater, all of which is hereinafterfully set forth in detail.

The elementary sections of which my heater is constructed are of three kindsviz., the end sections, of which one is placed at each end of the complete structure to formthe front of each of the minor heaters, the intermediate sections, several of which are placed between I said end sections,a11d also what I term the division-section, which forms a back common to the two minor heaters-and, as'its name implies, provides a division-wall between them.

To assist in the explanation of my invenvent-ion, I'have provided the accompanying drawings, illustrating the same, as follows:

- shown in Fig. 2 of the drawings.

serialliatwmll. (roman) e 1 Figure 1 is an elevation of my newly-invented heater, broken away in part to show in vertical section its interior construction. Fig. 2 is a horizontal view of said heater, taken on line 00 a; of Fig. 1, this view showing also, in dotted lines, the outlineof the ash-pit. Fig. 3 is a'horizontal sectional view of the central portion of my heater, taken on line y y of said Fig. 1. Fig. 4 shows in elevation one of the end sections of my heater. Fig. 5 is a similar view of the reverse side of the lower portion of said section. Fig. 6 shows in elevation oneof the intermediate sections. Fig. 7 is a sectional view of the lower portion of said intermediate section. Fig.8 is an edge view of'said end and intermediate sections, said view beingcommon to Figs. sand 6. Fig. 9 is an elevation of what I term the divisionsection. Figs. 10 and ll are edge views of said last-named section, taken from the opposite sides of Fig. 9. Fig. 12 is a sectional View of the lower portion of the division-section. Fig. 13 is a sectionalview of the upper portions of said end, intermediate, and division sections.

scribe the intermediate section of myheater, calling particular attention to Figs. 6, 7, and v 8, illustrating the same in detail. This section, as well as the end and division sections, is hollow, consisting of thin metallic walls, between which the water is confined while being heated. The upper portion 10 of the said intermediate section is of circular form, as shown in elevation in Fig. 6, and depending from opposite sides thereof are water- legs 11 and 12, that are shaped in cross-section as When the heater is assembled,-the water- legs 11 and 12 form the side walls of the fire-pot and combustion-chamber. Centrally located inthe portion 10 and extending through the same is a circular opening 13, and concentric therewith both' faces of the intermediate section are recessed to form circular depressions 14, leading from between legs 11 and 12 upward to. a point above the circular opening 13, at which point the circular wall l0',inclosin g said opening, is cut away or stopped off in the casting, as at 14:, providing communication between circular depressions 14 and the open- Referring now to thedrawingsJ will first deencircles the central opening 13.

ing 13. Crossing centrally the circular opening 13, preferably at right angles to each other and at angles of about forty-five degrees to the vertical center of the com plete heater are two Waterways 15, of approximately the same thickness as that portion of the section between the depressions 14.

The lower extremities of the legs 11 and 12 are connected by means of extensions 1112, leading downward and inward to and connecting with acircular chamber 16 in the line of the vertical center of the section. (See Figs. 0 and S.) The upper portion of each intermediate section has formed thereon a similar chamber 17, preferably of the same thickness as the section proper.

Located above chamber 16 is a boss 16, that is bored, as at 16*, to receive a bolt by means of which the several sections of the heater are tied together, as hereinafter explained, and crossing said intermediate section at a point below chamber 17 is a boss 17, that is similarly bored, as at 17, to receive a tie-bolt extending through the entire line of sections.

Formed on the extensions 11 12 of legs 11 and 12 are webs 18, the upper edges of which conform in outline to the shape of the gratesegments, in which webs bearings 18 are provided to receive the grate-bar journals.

Reference-number 19 denotes downwardlyextending plates formed on the confronting inner faces of the legs 11 and 12, which plates serve to guide the fuel to the grate, and thereby prevent its lodgment on the sides thereof. The end section of my heater which forms the front or outer sections of the said minor heaters is shown in detail in Figs. 4, 5, and 8. Said section in outline and general construction is the same as the intermediate section just described, and all points of correspondence are similarly lettered. In order that said section may serve as the front wall for the firepot, the portions thereof corresponding tothe legs 11 and 12 of the intermediate section are connected by a hollow wall 20, which latter also extends upward and The front face of wall 20 is preferably depressed, but to a less extent than the depressions 14 of the intermediate section; but the rear face of said wall is depressed considerably more than said depressions 14, thereby leaving the thickness of wall 20 approximately half that of the section as shown in Fig. 1. An opening 21 is provided in wall 20, through which the fire-pot may be reached, and in the opening 13, above referred to, the transverse waterways 15 may be omitted in order that free access may be had to the upper interior portion of the heater when necessary to clean the same.

The so-called division -section of my heateris illustrated in detail by Figs. 2, 3, 9, 10, 11, and 12 of the drawings, section in the main is like that of the intermediate and end sections already described, and allpointsof correspondence are similarly numbered. The said division-section is pref- The outline of this erably of somewhat greater thickness than the end and intermediate sections, and the portions 11 and 12, corresponding to the legs 11 and 12 of the intermediate section, are connected by walls 22, of plate form, whose opposite .faces are somewhat depressed. The circular opening 13 is provided in this section; but one side thereof is cutout, asat 23, through the portion 10 to the circumference thereof. Thewall 22 extends upward and partly encircles opening 13, thus forming on each face of the division-section a depression 14:, which enters the opening 23 at 23", at which point the encircling wall 10' of opening 13 is cutaway to allow communication between depression lat and said opening. The lower wall of the opening 23 is a continuation of the circular wall 10 of opening 13 and is denoted by reference-number 10.

Located in the circular opening 13 is an an gular deflector-plate whose faces are denoted by the reference-numbers 2 1 24'. (See Figs. 3 and 9 of the drawings.) The said faces 24 24 of the deflector-plate extend from the circumferential wall 10 of opening 13 to a point approximatelyin line with the vertical center of said opening, at which point said faces 24 24 meet, forming an acute angle, as shown in the Fig. 3.

Located on that edge of the division-section opposite opening 23 is a hot-water chamber 25, that is shaped in crosssection as shown in Fig. 3, and extendsfrom the lower portion of leg 12 upward to the chamber 17. Said water-chamber 25 conforms in outline to the ICO shape ofthe division-section, but has no water communication therewith.

The reference-number 26 denotes a boss formed on top of the chamber 17, which boss is bored and threaded to receive one of the outlet-pipes of my heater, as hereinafter fully described. The said division-section is provided with a lower portion 22, conforming in shape to the ash-pit of the heater, and the wall 22 extends downward into said lower portion to a point in line with or below the chambers 16 of the companion sections of the heater.

The wall 22 in said lower portion is provided with a boss 16", corresponding in shape to the chambers 16, and a bar 16 bridges the space between the walls 22 at the proper point to be bored to receive the bolt already referred to, by means of which the several sections are held together. Bosses 27 are provided on the opposite sides of the division-section to reoeive certain pipes, as hereinafter described. The lower part of the division section is formed merely as a thin web 28 to divide the ash-pits of the two minor heaters.

Reference numbers 29 denote cupped bosses formed on wall 22 to receive the rear ends of the grate-bars.

It is well understood by those conversant with the manufacture of this class of heaters that the various sections are usually cast in a single piece. This is true of the sections of the herein-described heater, and it will be understood from the foregoing description and from the drawings that the Water in each section, while having free course throughout that section,is,at the same time,not confined therein, but has communication with adjoining sections through the connecting- chambers 16 and 17.

In the process of assembling my heater a number of intermediate sections are placed on each side the division-section, the number of such sections on one side exceeding those on the other, and one of the front sections is then placed at each end of the structure, thus providing the two minor heaters of difierent capacity. The said end and intermediate sections rest upon ash-pits and 31, provided for the separate use of said minor heaters, and to tie the several sections togetherarod 33 is passed through the holes 16 near the bottom of eachsection of the complete structure, and a similar rod is passed through the holes l7 near the top of each of said sections. The opposite ends of the rods 33 are threaded to receive nuts 34, by means of which the several sections are forced into and retained in close contact with each other, it being of course understood that suitable packing may be employed between the sections to insure tight joints. The chambers 16 of each section are bored, as at 16, as shown in the drawings, Figs. 1, 4, 5, 6, 7, 9, and 12, to receive the shouldered ends of nipples 35, and the chambers 17 are similarly boredto receive nipples 36. Said nipples 35 and 36 are placed in position when assembling the heater and when the several sections are forced into close contact provide connections between the several sections thatpermit the water therein to pass freely from one section to the next adjoining one.

The reference-numbers 37 and 38 denote outlet-pipes leading from the chambers 17 at the opposite ends of the structure, and 39 denotes a similar pipe leading from the boss 26 of the division-section, the said pipes 37 38,

and 39 conveying water from the heater to radiators or for other uses. H

Inlet or return pipes for my heater are denoted by reference-numbers 40, which pipes enter the division-section at the bosses 27.

The grate-bars of my heater are denoted by reference-number 41. These bars have formed thereon the grate-segments 42 and are supported at various points by the bearings 18, formed in the Web 18 of each intermediate section. The upper edge of said webs conforms in outline to the shape of the gratesegments 42, as will be understood by reference to the dotted lines in Fig. 6, and at the points Where the bars :41 are engaged by the hearings in said webs the segment 42 is omitted and its place is filled by said web. (See Fig. 2.) The inner end of each gratebar engages and revolves in one of the cupped bosses 29, and the outer end passes through and is supported by a plate 43, secured to the front sections of the heater. The extreme outer ends of bars 41 are triangular, as shown, to receive the usual handle or wrench for rocking the same.

Reference-numbers 44and 45. denote, respectively, the fire-pot or feed-door and the door through whichthe interior of the upper portion of the furnace may be reached.

Number 46 denotes a collar that encircles the opening 23 of the division-section and is adapted to receive the smoke pipe 47, as shown in Fig. 3.

- It will now be seen,by reference particularly to Figs. 1 and 3 of the drawings, that when the several sections are clamped together, as described, the depressions 14 of all confronting sections will coincide and thus provide draftflues leading upward from the fire-pot around the Wall lOof the circular openings 13, and it will also be seen that the confronting depressions l4 will likewise register, thus permit.- ting a free passage of the products ofcombustion from the fire-pot to a point above opening 13 and thence downward into and throughsaid opening, as indicated by arrows in thedrawings. Said products of combustion travel through openings 13 until deflector-plates 24 24 are reached, which latter serve to turn the current of said products into the opening 23 and finally outward through the smoke-pipe 47. The depressions 14, confronting the opening 23 of the division-section, are stopped up by means of plates 48, as

shown in Fig. 3, and thus the direct passage from the firepot to said opening is prevented.

The'described current of the caloric products ofcombustion utilizes to the fullest extent snch products, and the construction of the various heater-sections presen ts the water to such products in the most advantageous manner. It will thus be seen by reference to the drawings that the products of combustion serve not only to heat the water when passing upward to the openings 13, but also when traveling through said openings influence the water within the-waterways 15, crossing said openings.- I

In Fig. l is shown a device by means of which the fire is automatically controlled. This is accomplished by a pipe 49, leading upward from the lower end of chamber 25 to a diaphragm in case 50, supported midway the length of the heater and near the upper portion thereof. Two levers 51 are supported in standards 52 on said diaphragm-case, and the longer ends thereof are connected by means of chains 51' to the ash-pit doors 30 31. The inner ends of said levers are secured to averticalrod 54, controlled by the diaphragm. As the temperature of the water in chamber 25 is varied by reason of the influence of the changed temperature of the water in the division-section, the diaphragm is correspondingly influenced to move the rod 54 to rock levers 5l,the movement of which latter causes the chains 51 to open or close the ash-pit tomatically.

It will now be understood that I provide practically three heatersin a simple structure-that is to say, I provide two heaters of different capacities that may be operated in dependently of each other, or they may be used together to providea heater of the capacity of the two minor heaters.

It will now be obvious that either of the two minor heaters could be manufactured and used as a complete structure and separate from its companion, in which case the rear section Would be substantially like the division-section here illustrated in Fig. 9, the only material difference being in the fact that the opening 13 would be circular, as in the front and intermediate sections, the smoke-pipe being then fitted to the rear of said opening.

Having thus described my invention, I claim- 1. In combination,inasingle structure,t-wo heaters of different capacities adapted for either independent or conjoint use, said structure embodying an interposed water-section that serves as the rear section of both of said heaters. I

2. Inasinglestructure,in combination.two heaters, set back to back, and an interposed rear water-section common to both of said heaters, said interposed section being formed with a smoke-exit and an angular deflectorplate 24 24:, substantially as and for the purpose specified.
