SPECIFICATION forming part 0f Letters Patent N0. 437,040, dated September 23, 1890.
Application iiledune 19, 1890. Serial No. 355,973. (No model.)
To .cr/ZZ whom it may concern: y l
Beit known that I, vCLARK OTIs,',a citizen of the United States, residing at Farmer Village, in the county of Seneca and State of New York, have invented certain new and useful Improvements in Steam-Boilers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to certain improvements in steam-boilers for generating steam for domestic purposes; and it has for its objects to provide a boiler that may be cheaply constructed, easily repaired and cleaned,and in whicha thorough circulation of water may be effected and dry or superheated steam gen-` erated, as more fully hereinafter explained.
The abovementioned objects I attain by the means illustrated in the accompanying drawings, in whieh- Figure l represents a vertical sectional view of my improved boiler. Fig. 2 represents a horizontal sectional View of the boiler on the line @c of Fig. l, and Fig. 3 a detail perspective View of one of the cast frames.
Referring to the drawings, the letter A i11- dicates the internal walls of the boiler, constituting the tire-box and combustion-chamber thereof. These walls are composed of four rectangular steel plates, connected at their side edges by means of angle-irons B, extending vertically the full length of their adjoining edges on the inside of the chamber formed by said walls, the angle-irons being bolted to the plates and suitably calked to form tight joints at the adjoining edges of the plates, or any suitable packing may be interposed between the angle-irons and plates for the same purpose.
The letterD indicates four rectangular castings of somewhat less width and length than the plates before mentioned, having their edges truly planed or otherwise iinished and setting against the outer surfaces 'of the said plates.
' E indicates aseries of four metallic plates, preferably of steel, which are of the same shape and size as the plates constituting the inner walls of the boiler. These plates set against the outer edges of the castings before mentioned and are bolted to the inner wallplates of the boiler by means of bolts F, eX- tending along the outside edges of the castings and threaded at their outer ends for the reception of nuts, so that the plates E maybel detachably secured to their seats for the purpose of cleaning or repairing the boiler. Across the inside of the chamber formed by the inner walls of the boiler extend a series l of metallic tubes l'l, preferably of wroughtiron, crossing each other in alternating series at right angles and communicating with the chambers formed by the castings and the inner and outer plates of the boiler. These pipes commence just above the tire-chamber of the boiler and terminate below the top thereof, as shown, occupying the lower part of the combustion chamber of the boiler. Above the said pipes are arranged aseries of larger pipes I, which also connect with the chambers formed by the castings of the boiler and the plates thereof. These pipes occupy the upper part of the combustion-chamber, and are above the water-line of the Waterchambers, forming,virtually, superheaters, by means of which dry steam is produced.
The letter L indicates the crown of the boiler, from which extends a smoke-stack M, and N the tire-door leading into the fire-box in order to supply the same with fuel. The tire-box at its lower part is provided with the usual grate P and with an ash-pit RA The water-chambers, formed by the boiler plates and castings, are connected at their lower parts to a water-supply pipe S by means of branch pipesT, in order to provide for illing said chambers and, in connection with the pipes H, to provide for a thorough circulation of water through the chambers and the rapid generation of steam therein.
The letter U indicates two steam-eduction pipes, extending from the upper portions or steam-spaoe of two of the water-chambers, through which the steam may be carried off for use.
Between the faces of the castings and the boiler-plates suitable packing may be interposed to form water and steam tight joints, or the met l may be calked for the same pur pose.
IOC
As constructed, it will be seen that the boiler can be readily set up or taken apart, rendering it inexpensive and providing for easily repairing and cleaning it.
To prevent the radiation, of heat, and thus economize fue1,the boiler may be inclosed in a jacket A of thin sheet metal, as shown in Fig. 1.
It will be perceived that no rivets are employed in the construction of the boiler, thus reducing the labor of putting the parts together and providing for readily taking it apart, and that by the arrangement of the internal circulating and superheating fines an extensive heating-surface is obtained, rendering the boiler very economical in its operation.
Itis evident that this boiler' may be em ployed with equal advantage for heating and supplying hot water for heating dwellings, rbc.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1. The combination, in a steam-boiler, of the rectangular inner walls, angle-irons connecting the adjacent edges of theinner walls and extending approximately the full length thereof, the castings removably securedv against the faces of the inner walls, the outer walls removably bolted to the faceslot the castings, thereby forming water and steam spaces, and crossed tubes connecting the op posite Water -spaces, substantially as described.
, 2. In a steam-boiler, the combination of rectangular inner walls connected together at their adjacent edges, rectangular frames or castings setting against the said inner walls,
outer walls removably secured to the said inner walls and setting against the outer faces of the castings, the latter being removably clampedv between the'two walls, thereby forming four separate Water and steam spaces, and circulating-tubes connecting these water and steam spaces, as and for the purpose described.
3. The combination, iny a steam-boiler, of the circulatingpipcs, crossing each other and connecting the water-chambers of the boiler andthe supplylpipe, and' branch pipes connectin g the said supply-pipe and Water-chamber together, whereby a thorough circulation of Water is effected in the boiler, substantially as set forth.
In testimony whereof I aix my signature in presenceof two Witnesses.
