Application filed April 9,1903. SerialNo. 151.827.
To all whom zit may concern.-
Be it known that we,-JULrUs F; ADAMs and FRIEDERIGH O. ADAMs. citizens of the United States, residing at Allegheny,-in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to hot-air gas-burning furnaces; and one object thereof is to provide an efficient burner and combustionchamber of simple and improved construction..
A further object is to provide a novel arrangement of flue-tubes which, in connection with a fume-drum of novel construction into which the tubes discharge, provide for effect ive radiation of practically all heat from the products of combustion before they pass to the chimney connection.
The invention consists in the novel struc.
tural features and combination of parts, hereinafter fully described and claimed, and illustrated by the accompanying drawings, wherem- Figure 1 is a perspective view of our improved furnace, portions thereof being broken away to illustrate the interior construction. Fig. 2 is a vertical sectional view taken on line 2 2 of Fig. 3, portions of the furnace interior being shown in elevation. Fig. 3 is a sectional plan view on line 3 3 of Fig. 2, a por tion of the combustion-chamber being shown in section. Fig. 4 is a vertical sectional view of the fume-drum, taken on line 4 4 of Fig. 5; and Fig. 5 is a sectional plan view of the same, taken on line 5 5 of Fig. 4. Fig. 6 is a plan view of one of the burner-sections. Fig. 7 is a cross-section of the same.
Referring to the drawings, 2 designates the outer casing of the furnace, having coldair inlets 3 at its lower end and outlets 4 at its upper end, to which are connected the warm-air conductor-pipes. (Not shown.)
The heat generating and radiating portions of the furnace are entirely inclosed by jacket 2 and consist, primarily, of a continuous tubular combustion-chamber 5, preferably of square outline, which is supported on legs 6, and rising from this chamber are the upwardly-tapering fume-tubes 7, which at tubes.
their upper ends open into and support fumedrum 8.
Within each of thefour sides of co1nbustionchamber 5 is a separate tubular burnersection 9, to each of which leads a separatelycontrolled gas-supply pipe 10, each pipe being provided with a mixer 1 1 and all connecting with main supply-pipe 12.
Tubes 7 rise centrally over the burners, and arranged in the latter in line with said tubes are thimbles 13, and immediately beneath these thimbles openings 14 are formed in the bottom of combustion-chamber 5, whereby provision is made for direct upward flow of air through the burners into the The burners are preferably formed withflat tops with circular series of gas-emitting -jet-holes 15 surrounding thimbles 13, whereby a central draft is provided for the ignited gas, which burns upwardly directly into the tubes 7. Additional jet-holes 16 in the sides of the burners further assist in com pletely filling the combustion-chamber with ignited gas. The lower portion of each burner-section is preferably rounded for the purpose of effectively directing the gas to the top and side jet-holes, while, on the other hand, the combustion-chamber is formed with a rounded upper portion to direct the ignited gases to tubes 7. Said tubes are upwardly tapered for the purpose of providing large heat-radiating area. this form serve to appreciably hold in check the upwardly-flowing gases and products, thereby increasing their heat-radiating efficiency.
With the combustion-chamber, tubes 7, and drum 8, arranged as shown, a verylarge area of heat-radiating surface is had, all portions of which are readily. accessible to the air rising within jacket 2 to the circulatingpipes. With the burner-sections under separate control all or only one or more of them maybe lighted, dependent upon the demands, We preferably provide a on the furnace. pilot-burner 26 within the front of the combustion-chamber and connected by pipe 27 with main supply 12. This pilot-burner is conveniently accessible and visible through door 5, and by keeping the same constantly burning the burner-section 9 immediately adjacent the same may be lighted at any time, together with any'or all of the other burner-sections.
'le our invention has been designed with special reference to the requirements of an eflicient and economical hot-air furnace, it will be understood that the underlying principles may be embodied in other forms of heating apparatus.
We claim as our invention 1. Improved heating apparatus comprising a combustion chamber, a fume drum above the chamber, a plurality of relatively small upwardly-tapering fume-tubes rising from the said chamber and communicating with the drum, and gas-burning means within the chamber.
2. Improved heating apparatus comprising a combustion-chamber of tube-like form extending around'or inclosing a verticallyopen air-space, 'a fume drum above the combustion-chamber, the drum having an airpassage formed therethrough from top to bottom which is in line with the air-space around which the cbrnbustion-chamber extends, a plurality of upwardly-tapering fumetubes connecting the chamber and drum, and gas-burning means within said chamber.
In testimony whereof we affiX our signatures in presence of two witnesses.
