IMPROVEMENT LN BOILERS FOR HEATING PURPOSES.
The Schedule referred to in these Letters Patent and making part of the same. A
v To all whom it may concern.-
Be it known that 1, JAMES A. MAYNARD, of New tonville, in thccounty of Middlesex and State of Massachusetts, have invented certain Improvements in Boilers for Heating Buildings and for other purposes, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawing making part of this specification, in which-- Figure 1 is a perspective view of my improved boiler.
Figure 2 is a longitudinal vertical section through the center of the's'ame.
Figure 3 is a transverse section through the center of the same.
Figure 4 is a horizontal section on the line a: x of fig. 2. v My invention consists in connecting two portions of a boiler by means of a series of tubes, through which circulates hot water or steam,'these tubes serving as radiators for heating the air which passes in contact with their external surfaces; and my invention also consists in the combination with the above of a circulator or division-plate, which is placed partially around the furnace within the boiler and extends to within a short distance of its top and bottom, whereby the water is caused to circulate continuously through the boiler and'tubes in order that'it may become rapidly heated.
To enable'others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.
In the said di-awing- A is the boiler, within the portion a of which is placed the furnace B, the tides b of which communicate with the smoke-pipe O.
The portions 0 d e of the boiler are connected together and. to the portion a so as to form a rectangular opening, D", which is crossed by two series of tubes h i, the extremities of those it opening into the portions 0 0, while the extremities of those 1 open into the portions 0. d of the boiler.
These tubes are heated by the hot water and steam which circulate through them, and serve as radiators to heat the air which passes up through the rectangulfar opening 1) into contact with their exterior s uraces.
The interior or each portion a c d e of the boiler is provided with vertical tubes k, open at each end 5 6.
These tubes are heated by the hot water and steam withihthe boiler, and serve as,radiators for heating the air which passes up through them in contact with their inner surfaces.
The air, after being heated by passing up through the rectangular opening D andtnbes kyenters a chamber, not shown, surrounding the boiler, from which it is conveyed by suitable pipes to any part of the buildiing to be heated.
In order to facilitate and insure the desired circulation of the water within and through the boiler and tubes h i, aplate'or circulator, E, is made to extend partially around the furnace B from 7 to 8, see fig. 4, and to within a sho'rtdistance of the top and bottom of the boiler, leaving passages 9 and 10, by whichconst-ruction the cold water at the bottom of the pormay be used to generate steam for various purposes.
Claims.
1. A boiler composed of two or more portions, connected by the tubes h or i, which serve as radiators for heating the air passing incontact with their external surfaces, as and for the purpose described.
2. The circulator E, in combination with the furnaceB and a boiler provided with radiating-tubes h or 1 operating substantially as set forth.
3. The combination of the portipns a c d e with their radiating-tubes k, the radiating-tubes h t, furuace B, and circulator E, operating substantially in the manner and for the purpose described. I
Witness my hand this 20th day of December, A. D. 1870.
