WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 784,964, dated March 14, 1905. Application filed September 28, 1904. Serial N0. 226,304.

To all whom, it nur/y concern:

Be it known that 1, lVILLIAM S. ROATH, of the city of Canton, county of Stark, and State of Ohio, have invented new and useful lmprovements in rater-Heaters, of which the following is a specification.

The invention relates to water-heaters made of a series of vertical sections assembled side by side; and the principal objects of the improvements are to arrange the waterways so as to present the maximum heating-surface with reference to the grate area; to carry the lire-gases without separation along the waterways and not across them in the first instance and then to accumulate the gases in a common superheating-chamber around the water-tubes above thc smoke-Hue to permit a complete combustion; to arrange the waterwaysfso the heated water will travel in one direction only from the several locations to the top of the heater to create a free and delinite circulation; to directly join the sections by nipples at the lowest and highest points, so water of different temperatures will iiow freely and equalize between the several sections, and to construct and arrange the parts so that all the heating-surfaces can be readily reached for cleaning. These objects and other minor ones are attained by the construction and arrangement illustrated in the accompanying drawings, in which Figure l is a side elevation of an intermediate section of the heater with the adjacent and adjoining parts thereof in section;- Fig. 2, a front elevation of a heater made of three intermediate and two side sections with parts broken away to show some details in' crosssection; Fig. 3, a vertical longitudinal -section of one of the intermediate sections; Fig. 4, a

section of the heater on line 4 4, Fig. 1; Fig.

, a section of the heater online 5 5, Fig. l; Fig. 6, a fragmentary side View showing an alternate way of connecting the smoke-pipe to the breeching; Fig. 7, a detached perspective view of the middle intermediate section, and Fig. S a similar view of one side section with parts broken away to show some details in section.

Similar numerals refer to similar parts throughout the drawings The intermediate sections l and l are each provided with an exterior waterway forming a rim for the section, which rims when abutted laterally constitute the back, top, and, above the {ire-box 2, the front of the heater. Each exterior way comprises the stemway 3, extending along the back of the fire-box, the back way 4, preferably extending' first rearward and then directly upward along' the back of the heater, the top way 5, inclining along the top of the heater from the rear way upward to about the middle, thence downward to the front thereof, and the front way 6, extending directly downward along the front of the heater to the top of the fire-box. ln the lower Aend of each stemway are provided the lateral apertures 7, and in the middle and highest part of each top way are provided the similar lateral apertures 8, in which apertures the nipples 9 are inserted when the sections are brought together, thus making two continuous lateral channels, one at the bottom and one at the top of the heater, by means of which channels the water can circulate freely from one section to another. One or more of the intermediate sections is provided with an inlet-aperture l() in the back wall of the stemway, preferably opposite the nipple-apertures, in which inlet-aperture is connected the inlet-pipe 1l for the return of the colder water from the heating system, (not shown,) and also with an outlet-aperture l2 in the top wall of the top way, at the highest part thereof, in which aperture is connected the outlet-pipe 13 for the iiow of heated water into the heating system.

The interior waterways comprise the

tubeways

14, 14, and 14b and the baiile-ways l5 and 16, which are inclined upward and forward and communicate from the back way to either thel front way or top way, as illustrated. The tubeways are formed less in diameter than the width of the exterior ways, so that when the sections are assembled there is quite an interval between the tubeways. The baliieways, however, are of the same width as the exterior ways, so that these ways abut side by side when thesections are assembled and constitute two laterally-continuous baffle-walls l5n and 16. The rear ends 15b of the lower IOO - plate for cleaning the same.

baffle-ways 15 are reduced to the width of the tubeways, so that the lire gases can pass around the rear ends of the baille-wall 151L and through the intervals thus formed, and the forward ends 16" of the upper ba'flie-ways 16, together with the considerable portion 6L of the front ways 6 above the lower balile-plate, are reduced to the width of the tubeways, so that the fire-gases can pass around the forward end of the baille-wall 16lL through the intervals thus formed. The doors 17 are hinged on the front of the heater and normally close the intervals in the Vfront wall; but when these doors are opened these intervals give access to all the heating-surfaces of the several tubes and baille-ways above the lower baffle- The heatingsurfaces below the lower bathe-plate can be readily reached from the lire-box. rlhe parts 11 of the back ways near and above the upper baffle-ways are reduced to the width of the tubeways, and the intervals between these reduced parts make an outlet for the smoke and other products ot' combustion. The breeching 18 is attached to the back of the heater, so as to cover all the slnoke intervals in the back, and by attaching the reducing-elbow 19, as shown in Figs. 1 and 5, the smoke-pipe 2O can be directed upward, or by attaching it as shown in Fig. 6 the smoke-pipe can be directed rearward.

Each side section 21 is formed with one half just like the adjoining intermediate section, and the several tu bes and baffle-ways are connected in their middle lines by the short partitions 22, from which partitions the outer walls 23 of the side sections and of the heater are spaced at an interval to form the side ways 211, which extend over the entire sides of the heater. The side sections and side ways are extended downward and 'forward to 'form the side walls of the lire-box, and it is preferred to connect the lower forward corner of these sections by the crossway 26, having con'nnunicating nipples, as at 27. The sections of the heaters are held together by the tie-rods 28 passed tln'ough the lugs 29 on the side sections, and the door 30 is hinged on the front of the heater to close the lireboX. The heater thus assembled is preferably set on a suitable base, as 31, which forms an ash-pit, and the bottom of the lire-box is provided with the usual grate-bars 32.

When the gases rise from the lire,they travel iii-st upward and backward along' and around the tubes 14, being so diverted by the baffleplate 15, thence upward around the reduced rear ends 15" of the baille-ways and forward along and around the tubeways 141, being so diverted by the baffle-plate 16, thence upward along and around the reduced parts 6 of the front ways and the reduced forward ends 16b of the baffle-ways 16 into the superheating chamber formed by the intervals around the tubeways 14h. The gases then travel backward along and around the tubeways 14Cb to the smoke intervals between the reduced parts 1-1 of the back ways and on through the breeching and smoke-pipe. As the lire-gases travel through the heater they are not separated at any point except as they surround the various tubeways, and as a result they are free to mingle and combine in the proper proportions for complete combustion. rlhis is specially true of that part ofthe heater above the smoke-apertures, wherein unburned gases are retained until proper proportions are present to cause complete combustion, and for this reason this chamber is well named a superheating chamber. Gases are thus utilized which would ordinarily pass out unburned through the smokepipe.

As the water is heated in the several interior ways it naturally iiows upward and forward to the 'front ways, thence upward in the Jfront ways and rearward in the forward part of the top ways to the highest parts thereof, from which it passes upward into the heating system through the outlet-pipes. The cooled water in the heating system naturally Hows downward and enters the heater through the inlet-pipes into the lower ends of the stemways, vfrom which it ascends, some of it through the back ways, and passes into the rear lower ends of the interior ways. The cooler water within the heater naturally flows downward to and through the back ways until water of equal temperature is reached, which is joined, and the upward Aforward flow through the inter ways is resumed.
