C. R. KLIN E COMBINATION BOILER Filed Sept. 9. 1920 Patented July 241-, i923.

CHARLES It. KLINE, OF READING, PENNSYLVANIA.

COMBINATION BOILER.

Application filed September To all whom it may concern.

Be it known that 1, CHARLES R. KLrNn, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Combination Boilers, of which the following is a specification.

My invention relates more particularly to boilers adapted for heating residences or like purposes, my main object being to provide for the convenient and economical use of such boilers in accord with the greatly varying needs incident to variations in weather and other conditions.

The invention consists essentially in CO1 i bining with an ordinary firegrate boiler, 21 separately formed built-in section provided with a fluidfuel burner and conduits and forming a separate combustion chamber arranged in communication with the same passage-ways through which the solid-fuel products of combustion are discharged; so that said fluid-fuel sect-ion may be readily and effectively employed either alone to produce the relatively small amount of heat required for distribution in moderately cold or damp weather, or to supplement the solid fuel heat production when called for; as fully described in connection with the accompanying drawings and specifically pointed out in the claims.

The drawing illustrates the application of my invention to a known type of boiler, in a. simple manner adapted to make clear the essential features of the invention; Fig. 1 showing a sectional view of my fluid-fuel section in connection with the adjacent parts of a sectional boiler and with a partial front view of the latter; and Fig. 2 showing a sectional view on the line 2-2 of Fig. 1

The known type of boiler indicated made up of a series of connected water-coin taining sections 5, 5, 5, forming in combination with an ash-pit base portion provided with door fronts 7 and 8, a suitable solidfuel combustion chamber, with connnunicating passage-ways, as 9 and 10, through the connected water-containing sections for dis charging the products of combustion. specifically indicated, these sections form a so-called side-feed boiler having a relatively wide fuel and combustion chamber with two solid-fuel firin doors 11 and ash-pit doors 12; and my separately operative fluid-fuel section 20 is shown as located midway be- 9,1920. Serial No. 409,079.

tween these two firing doors, and arranged in communication with the sections 5, 5, on each side thereof.

My special section 20, as shown, is made to correspond in general form with the cooperating ordinary water containing sections 5. but provides in itself a combustion chamber 21 separated from the adjacent solid-fuel combustion chambers by spacedapart water walls 22; said chamber 21 being in communication above with the passageway 9, through which the products of combustion from chamber 21 are also discharged into thechimney-connected passage-way 10, and the water-containing space being in communication withtha't of the sections 5 as usual. The section 20 is carried upon integrally formed wall or partition plates 24;, 241-, as indicated, which form a separate chamber 25 on the level of the adjacent ashpit chambers 27, and below the water-wall bottom 26 of the combustion chamber 21. Through the front wall 28 of this lower chamber 25, which may be provided with a doored aperture 84, extends a conduit 30 for the fluid-fuel, liquid or gass, to be used in the combustion chamber 21; which conduit passes through the bottom 26 and is connected to a suitable burner 31 in the chamber 21; air passages 32 to the latter being also provided as indicated. A suitable opening is provided for access to the chamber 21, through the front wall thereof, to which a door may be insulatingly applied as shown in my Patent No. 1,319,096 issued Oct. 21, 1919.

In operating my improved boiler all the products of coml'mstion, whether from solid or fluid fuel employed, pass through the section passage-ways 9 and 10, to the chimney; but either the solid fuel or the fluid fuel may be used independently, or both may be used together, as weather or other conditions may make desirable; the fluid fuel being very conveniently, satisfactorily, and economically employed alone during the early and late months of the cold season 1' occasional damp weather, and serving to readily supplement the usual solid-fuel heat broduct-ion in extreme weather. The application of the invention involves comparatively inexpensive changes in constructions heretofore employed, and the showing specifically set forth may be readily modified to suit desired patterns and arrangements.

It will be understood that the coal heated I water holding sections 5 are connected to each other by the nipples 35, and that the gas heated water holding section 21 is connected to the contiguous coal heated sections 5 by the nipples 36, so that a free and unimpeded water circulation is permitted, the inlet and outlets for the sectional boiler being of the usual character and requiring no further description. The back flue 10 of the gas heated section 20 may be connected with the fiues' 9 in any suitable manner as by the flue 37, said flue 10 having a connection or exit to a chimney (not shown) as hereinbefore referred to.

What I claim is:

1. In a device of-the character stated, a plurality of water holding sections, provided with transveise flues and communicating water passages, and a grate for the reception of solid fuel, in combination with a water holding section adapted to be heated by gas, said latter section having a water connection to said other sections, and a flue in communication with said transverse fiues, a gas burner located in the lower portion of said gas heated section, upright water j acketed walls in said gas heated section located on each side of said gas burner, and a support for said gas burner having vertically connection to the other sections and an outlet flue in communication with said transverse flues, upright bottom walls upon which said gas heated section is supported forming a lower chamber, upright water 1' acketed walls for said gas heated section supportedupon said bottom walls and having a combustion chamber formed therebetween, a gas burner positioned in the lower portion of said combustion chamber between said water jacketed walls, and ports in proximity to said gas burner leading from said bottom chamher to said combustion chamber for conveying air into the latter from said bottom chamber.

In testimony whereof I affix my signature.

CHARLES R. KLINE.
