WATER-HEATER.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed December 19, 1914. Serial No. 878,179.

To all whom'it may concern:

Be it known that I, Gnoncn A. S ms, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Water-Heaters; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to improvements in water-heaters, and particularly to a type of water-heater adapted to utilize the exhaust gases from internal combustion engines.

The object of my invention is the construction of the heaterof substantially duplicate sections preferably cylindrical in form, the lowermost section being provided with a water inlet and the uppermost section with a water outlet, the sections of the heater being provided with peripheral flanges which engage each other and form the outside shell of the heater when super- 1 imposed upon each other, and centrally secured together by means ofscrew threaded sleeves whereby the expansion and contraction of the sections are uniform- The features of this invention are hereinafter fully set forth and explained and illustrated in the accompanying drawings, in which:

Figure 1, is a view of my improved water-heater partly in elevation and partly in section. Fig. 2 is an enlarged view in section of one of the duplicatesections of the heater. Fig. 3, is a transverse section'of the heater on the line w-m in Fig. 1, looking in the direction of the arrow.

In the construction of my improved water-heater thus illustrated, A, represents the base of the heater preferably supported on legs a. This base A, has formed therein a chamber A, and is provided with a pipe B, for conveying the exhaust gases of'the en-- vided at one side with a water inlet C and isprovided with a screw plug G which closesthe central opening C in the bottom of the section C, to prevent the passage of water into the chamber A. In this section then are alsovertical passages C by means whereof the gases'pass up through the sectionC, into an annular chamber 0?, between the section G, and the next superimposed section D. v

The intermediate sections D, between the lowermost section C, and the topmost section, are clearly illustrated in Fig. 2, and are each provided with a circumferential flange D, around its base, and a circumferential flange D around its top; the base flange D, fitting into the top flange D as clearly shown in Fig. 1, which flanges are preferably cemented to each other, the spaces between the sections forming the chambers (1. Leading vertically through each of these sections are tubes D for conveying the hot gases from one of the chambers d, to the next chamber d, above it.

To convey the water from one section to another, I, provide central internally screw threaded openings E,'in the bottom and top of each section, and connect these openings E, by means of externally screw threaded sleeves E The waterpasses up through the lower sleeve E, into the section D, under the central web D therein and then under said web tothe annular. passage D and back over the web D to the central sleeve E in the top of the section and then throughsaid sleeve into a like sleeve E, above it, as clearly shown by the arrows in Fig. 2, andso on up until it reaches and enters the topmost section F, from which it is discharged through the outlet pipe G, the top, central. opening F, in the top of the topmost section F, being closed by a screw plug Ft.

Upon the top' of the topmost section F,

there is a top plate H, provided with a downwardly extending circumferential flange h, which engages the circumferential flange f, on the top of the section F, where it is secured by means of cement. The top plate H, is preferably further secured to the section F, by means of bolts 72.. To the. central part of the plate H, there is secured a gas discharge pipe I, through which the gases passing up through the heater are discharged.

Inoperation the hot gases enter the heater -Fig. 2,11iiti1it reaches the to section F,

1 and water assages therein, superimposedthrough the pipe B, passing into the chamber A and thence upward through the tubes C into the chamber d, and thence through the tubes D successively from one chamber to another between the successive sections until it reaches the chamber at the top of the section F, from which they pass out through the gas discharge pipe Meanwhile the water to be heated enters the lowermost section'C, through the pipe C and from it into and through the intermedi ate sections 1), as indicated by arrows in from "which it is discharged throngh the pipe G.- The'important features" of this invention are cheapness and novelty of con- 1.. N, ,'.1 V 4,. struction, freedom from accident when in operation, and efficiency from the 1ar 'eheatingsurface towhich thewater is ex osed duringits passage through the heater.

Havingthus described my invention so as to enabl others to construct and utilize the same, what I claim as new anddesir'e to se cure Letters Patent is p 1. In a water-heater the combination of a series of inte ral sections having heating fluid passages therethrough and'therebetween upon each other, with the water passages therein, centrallyconnected, and flanges on said sections incl'osing the spaces between the same, substantially as set forth.

" 2. In a water-heater, the combination of a series, of integral sections superimposed upon each other, each having heating fluid 1 passages therethrough and therebetween,

and water passages therein central waterconnections betweensaid sections, over-lapa vmost section, a gas inlet communicati g with ping flanges on said sections inclosingf the spaces therebetween, a water; inlet in the lowermost section, a Water outlet in the top- 'thejgas passages in said sections, and a gas "water passages and centr l water inlet and i v I v v Copies of this patent maybe obtained mi outlet for discharging the hot gases from the topmost section,,substantially as set forth.

3. An integral water-heater sectionhaving' heating fluid passages therethrou'gh,

outlet openings, overhanging integral flanges on said sections one ofwhich is of less diameter than the other, substantially as set forth.

at. An integral water-heater section having heating fluid passages therethrough,

water passages and central water inlet and outlet openings therein, a horizontal web dividing said water passages so that the water flows from the inlet outward under said web, overhanging integral flanges on said sections, one of which is of less diam eter than the other, and inward to the outlet above said web, substantially as set forth.

The combination in a water-heater ofa series ofintegral sections fitting upon each other, each having lower and upper water passages communicating at the peripheries a series of integral circular sections. the peripheral walls of which, project beyond the flat sides of the body portion thereof and are adarggted to vtelescopically fit each other and formthe outer Wall of the heater, having lower and upper ater passages connecte ing at the peripheries of the sections, a central water inlet andan outlet atthe top and bottom of each section, and vertically heating' fluid passages through each section, water connections between the outlet of. one

section and the inlet ofthe next section, av

water inlet in the lower section and a water outlet in the top section, a base secured to the bottom section having a heating fluid so i inlet therein, and a plate secured to thetop section having a heating fluid outlet therein,

substantially as set forth I p I In testimony whereof I afiix my signature,

in presence of two witnesses. v
