HENRY STANTON, OF FLUSI-IING, OHIO.

HEATER OR BOiLER.

SPECIFICATION forming part of Letters Patent No. 509,495, dated November 28, 1893.

Application filed January 26, 1893- Serial No. 459,800. (No model.)

Be it known that I, HENRY STANTON, a citizen of the United States of America, residing at Flushing, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Heaters or Boilers, of which the followingis a specification, reference being had therein to the accompanying drawings.

This improvement relates to a boiler or water heater which maybe either used for raising steam for power of heat or simply as a water heater, and the invention consists in the peculiar arrangement, construction and combinations of parts hereinafter more particularly described and then definitely claimed.

In the accompanying drawings-Figure 1 represents a vertical longitudinal section. Fig. 2 is a vertical cross section through the line or :0 Fig. 1.

Referring now to the details of the drawings by letter--A represents the boiler, made preferably in two main sections B B which are united at top to a hollow casting O by pipes D D, Fig. 1, and at bottom to another hollow casting E by pipes F F, as shown in Fig. 1. To the top casting C is connected the outgoing pipe G and to the bottom casting the return or feed pipe G as the case may be. These sections are made of cast iron and of a thickness according to the pressure to be carried, and their opposite plates are to be connected by studs 11 cast integral with the section. The most of these studs, if not all, are provided with an extension h which projects down into the path of the products of combustion from the burning fuel on the rocking grate I.

I may make the bottom plate of the sections plain as shown in the upper section or waved or corrugated as shown in the lower section, in which case I make the studs of different lengths as indicated. I surround the boiler with the usual brick setting J in which I set appropriate soot doors K and provide the usual furnace and ash pit doors L L. At M is indicated the smoke flue, and at N is a bridge over which the products of combustion pass as they leave the furnace. By this construction, I produce a heater or boiler which will be found very rapid in heating water or raising steam, and economical of fuel, as the studs will absorb heat from the products of combustion and transfer it to the water very rapidly, and this is further assisted by the waved or corrugated bottom plate and by the heated products of combustion having to descend so low before they rise and pass out, as indicated by the short arrows. The long arrows indicate the course of the Water.

As will be seen by the short arrows, the products of combustion first pass over the bridge, then under the first section, and up between the two, then down over the top of the upper section to the flue.

Although I have shown the sections with different bottoms-one being straight while the other is corrugated-J prefer the one that is corrugated on the bottom, as that gives the most heating surface; and moreover, when the sections are arranged inclined over the path of the products of combustion, as shown, said products of combustion strike directly against said corrugations instead of gliding past the heating surface as they do when a straight surface is employed. I prefer'to leave the upper side of the section smooth, as bythis means it is more readily kept clean, for if the upper side -were corrugated, the ashes, cinders, &c., carried along with the products of combustion, would lodge in the corrugations; whereas when the section is made with a smooth upper surface, the ashes, 820., will slide downward off of it, when inclined as shown.

I am aware that it has been proposed to connect the opposite sides of boiler sections by means of wrought iron studs which project through one of the sides and into the path of the products of combustion, but I have found this to be objectionable as the wrought iron projections are more readily burned away and are thus destroyed and become useless. Moreover the large number of joints necessary with such a construction causes leakage, and the cast-iron studs employed by me constitute better conductors than wrought iron studs.

What I claim as new is-- 1. A boiler section having two opposite sides connected by studs whose ends project into the path of the products of combustion, said opposite sides and studs being cast integral, substantially as described.

2. A boiler section having one or more of combination withachimney set over the lower its sides corrugated, and the two sides conends of the sections, whereby the products of nected by studs cast integral with the sides, combustion are compelledto takea circuitous [5 and projecting from the corrugated surface, route, substantially as described.

5 substantially as described. In testimony whereof I affix my signature,

3. In a heater or boiler, two sections set diin presence of two Witnesses, this 23d day of agonally in a casing having an inclined top, January, 1893. one section having its upper end close to said r I w T casing and a space between the lower end I HENI STANlOk' 10 thereof and the casing, and the other section Witnesses:

having its lower end close to said casing and DANIEL H. WALKER, its upper end at a distance from the same, in W. W. COWEN.
