UNITED STATESL PATENT FFICE.
DOCTOR FRANKLIN MORGAN, OF CHICAGO, ILLINOIS.
BOILER FOR HOT WATER oR STEAM.
, SPECIFICATION forming part of Letters Patent No. 568,167, dated September 22, 189 6.
' Application filed January 15, 1896. Serial No. 575,664. (No model.)
T 0 all whom it may concern:
Be it known that I, DOCTOR FRANKLIN MORGAN, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Boilers for Heating Water or Generating Steam,
of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description.
The object of myinvention is to obtain a boiler for heating water or for generating can be readily removed and replaced by others.
Figure 1 of the drawings referred to is a front elevation of a boiler embodying my invention; Fig. 2, a vertical sectional view thereof on line 2 2 of Fig. 1, viewed in the direction indicated by the arrows; Figs. 3, at, and 5, respectively, horizontal views on lines 3 3, 4 4, and 5 5, respectively, of Fig. 2, viewed in the direction indicated by the arrows; Fig. 6, a perspective view of a division-plate forming one of the elements of the stove embodying my invention, by means of which downward currents of products of combustion are deflected and made to ascend.
is used to designate such part throughout the several figures of the drawings wherever the same appears.
A A is the outer shell or case of the boiler; a, the fuel-feeding door; a a, cleaning-doors, and a the ash-pit door. A Fig. 2, is a cylinder having flanges a a at the ends thereof. Cylinder A rests on the top A of part A of shell A A and is supported thereby, and the bottom A of part A of the shell A A rests upon and is supported by such cylinder A Water-in part A of shell A A extends through the cylinder A into the part A of such shell and around flues B B. B B are flues through which the products of combustion extend upward, as will be hereinafter fully described, and EB are fiues through which such products extend downward. C C are circulatingtubes connecting part A of shell A A with part A thereof.
D is a cylinder within partA of shell AA, having annular flange cl at the bottom thereof and closed at the bottom thereof and closed at the top by the top cl. CylinderD forms the inner wall of a water-leg of which annular flange cl is the bottom, and through which water-leg and annular flange cl the flues B B extend. A of shell A A.
E is the base of the shell A A, and e is an annular flange on the upper edge thereof.
F is a ring resting on and supported by the annular flange e, and G is a casting resting on and supported by ring F.
His the fire-pot of the boiler, having flange h at the upper end thereof, such flange resting on the upper edge of cylinder I, such cylinder resting on the casting G. Between the fire-pot H and the cylinder I there is the annular chamber 2', and h are apertures through the walls of the fire-pot H, through whichapertures airoextends from the annu lar chamber (or space) i into theproducts of combustion in the fire-pot as such products are about to leave such fire-pot. 7L2 7?? are grate-bars extending a short distance upward on the wall of the fire-pot I-I. The ordinary grate-bars h h extend across the bottom of the fire-pot.
J is a circular casting having ends K K integral there with or sec ured thereto, as pre- A letter of reference applied to a given part part A, cylinder A and wall a of the shell A A) downward to and into this chamber J.
J is an annular chamber around the lower end of the part A of shell A A in front of the ends K K of casting J. The bottom of such chamber J 2 is formed by the ring F, the top Annular flange d is secured to part ICO by the ring d, (or annular flange d to cylinder 1),) through which flange the fines B I3 extend, and by the casting G with ends K K and a portion of the part A of shell A A.
M is an annular space or chamber between the cylinders D and I, into which the products of combustion extend directly from the chamber or space N above the fire-pot II.
The operation of the boiler embodying my invention is: The products of combustion of the fuel in the fire-box I'I extend upward therefrom into the space or chamber N, such products receiving, as they pass by the apertures 72- h, additional and heated air coming through such apertures from the annular space 2'. From chamber N the products of combustion extend downward through the annular space M, combustion therein, as well as in chamber or space N, being obtained by the addition of the heated air through apertures h h. The product-s of combustion in the annular space M extend downward into the annular space J being prevented from passing into the chamber or space J by casting J and ends K K thereof. From chamber or space J 2 such products of combustion pass upward through the fines 1:3 into the chamber J and from thence downward through fines B into the chamber J, and from thence to the smoke-escape L and to the chimney. The shell or case A A having water therein to about the water-line, (indicated in Fig. 2 by dotted line W,) such water extends downward through cylinder A into the water-leg hereinbefore described and around the lines B B, and circulation of such water is secured, as the same is heated, through the circulatingtubes 0 C.
It will be observed that in a boiler constructed as hereinbefore described no water is in contact with the back of the fire-pot II, but, on the contrary, there is surrounding such fire-pot the annular space 2', between the firepot and cylinder I, into which space air is freely admitted from the ash-pit P, and also the space or annular chamber M, into which the heated products of combustion are delivered from space or chamber N. By this construction I am able to obtain very complete combustion of the fuel in the fire-pot, and by the admission of the additional and heated air through apertures 72. h to the products of combustion about leaving such firepot I obtain still further increase in combustion. I find that without the apertures h 7L, or even the annular space i, remarkably good results are obtained by me in this boiler, although I prefer to include both the space 2' and the apertures h h in a boiler completely embodying my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A fire-pot having double walls, an annular space between such walls, an additional annular space between the fire-pot and the wall surrounding it, means for admitting air to the annular space between the walls of the fire-pot and means for delivering such air to the gaseous products of combustion obtained in the fire-pot before the same enter the second annular space, to which they are delivered over the rim of the fire-pot; substantially as described.
2. A fire-pot having double walls, an annular space between such walls and an additional annular space around the fire-pot communicating therewith, flues communicating with the outer annular space, means for admitting air to the annular space between the walls of the fire-pot and means for delivering such air to the gaseous products of combustion obtained in the fire-pot before the same enter the flues; substantially as described.
3. A iire-pot surrounded by a water-leg, such fire-pot having an annular space between the walls of the fire-pot and the waterleg, to which space the products of combustion are delivered over the rim of the fire-pot, and down which such products pass before entering the tubes of the water-leg and having an additional annular space between it and the first-named annular space, means for supplying air to the last-named annular space and means for discharging air therefrom to the products of combustion leaving the firepot; substantially as described.
at. A fire-pot surrounded by a water-leg, such fire-pot having two annular spaces or chambers surrounding it, one of such annular spaces communicating with the ash-pit and the other thereof communicating with the fire-pot, to which last-named annular chamber or space the products of combustion are delivered over the rim of the fire-pot and, down which such products pass before entering the tubes of the waterleg; substantially as described.
5. A fire-pot surrounded by a water-leg, such fire-pot having two annular spaces or chambers surrounding it, one of such annular spaces communicating with the ash-pit and to the fire-pot through apertures near the top thereof and the other thereof communicating with the fire -pot, to which last-named annular chamber or space the products of combustion are delivered over the rim of the fire-pot and down which such products pass before entering the tubes of the water-leg; substantially as described.
6. A vertical boiler having a circular water-leg, flues extending through the boiler and water-leg, a second boiler above the firstnamed one, a chamber between the boilers with which chamber the tines communicate and a passageway for water between the boilers, in combination with a fire-pot having an annular space or chamber between it and the water-leg, and a partition extending partly around the fire-pot at the bottom of the annular space or chamber, whereby the products of combustion from the fire-pot extending therefrom and down the annular space will be deflected into some of the flues in the water-leg and extend upward therethrongh tween it and the water-leg, the inner space communicating with the ash-pit and with the fire-pot near the top of such fire-pot and the outer one having a partition at the bottom thereof extending partly around the boiler and communicating at its upper end with the fire-pot, whereby the products of combustion from the fire-pot extending therefrom into such outer annular space and down the same will have fresh and heated air delivered thereto as it leaves the fire-pot and after extending through such annular space will be deflected into and extend upward through some of the fines into the chamber between the boilers and from thence will extend downward through the remaining flues and to the chimney; substantially as described.
