STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 611,083, dated September 20,1898.
Application filed March 26, 1898.
To all whom it may concern.-
Be it known that wefJonN STEEL DIXON SHANKs and ROBERT KELLY, J r., subjects of the Queen of Great Britain and Ireland, residing at Belfast, in the county of Antrim, Ireland, have invented certain'new and useful Improvements in Steam-Boilers and Steam- Condensers and We do hereby 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.
This invention relates to improvements in steam-boilers and steam-condensers, the object being, in water-tube boilers and other boilers, to provide'a means for producing great power in small space and to provide the maximum of strength with minimum of weight.
In water-tube, boilers we use a number of tubes of small diameter and any convenient length. There is an outer and an inner tube-that is, a small tube is placed inside one of larger diameter and the water of the boiler is contained in the annular spaces between them. These tubes may be plain and cylindrical; but to provide for greater heating-surface in the boiler we flute longitudinally, except a short distance at ends, either one or both the tubes.
We provide for the reception of the ends of the tubes vertical rectangular boxes or headers, and into holes in the faces of the boxes the larger and outer tubes are inserted and fixed by being expanded, and we prefer, as further security, to form grooves in the walls of holes into which the tubes can be forced by the expander-tool. The inner tubes extend to the outer walls of the vertical headers and are secured thereto in the followingmanner: Holes are bored in the outer walls of the headers of sufficient diameter to allow of the larger tubes being'freely passed through them. These holes are then tapped out to receive a plug of brass or other suitable material, the plug being of taper form and screwed to fit the thread in the hole of header. The plug is bored out and screwed to take screwed end of inside tube and can be further secured by a lock-nut5 but we preferably employ the following manner of Serial No. 675,217. N 11 1 0 securing the inner tube to the outer wall of header: The plug is bored out parallel and to a diameter larger than that of the'inner tube, the ends of which are turned on the outside to a taper and screwed on inside to take a hollow plug which is screwed on out side to fit the screwed hole of the tube. The neck of this plug under its head is turned taper. A ring, preferably of copper, is fitted into the plain hole of brass plug having its inner side of the shape of a double cone. The taper end of inner tube is let into taper of copper ring, and when the hollow plug is screwed up the copper ring is compressed between the inner tube and cone of plug and expanded against the holein brass .plug, the combination making a water and steam tight joint and permitting of easy removal for repairs or cleaning. We make the ends of all the tubes larger in diameter than the body of same for the purpose of easy removal.
The tubes and headers we make preferably of mild steel, and the headers may be two or more, as desired, and We use a cylinder or cylinders over them for collecting the steam.
The headers and tubes are incased in walls of fire-clay, supported by steel or iron plates, the fire being underneath the nest of tubes. The gases from it pass through the spaces be tween the outside tubes into a chamber, then through the inner tubes to the smoke-box and chimney.
The tubes we place preferably raised at one end; but they may be horizontal.
The outside tubes are fluted on the outside only, the inside being plain, the inner tube being fluted inside and out.
In Lancashire and Cornish boilers we flute the furnace and internal flues longitudinally and in short lengths up to a short distance from the cylindrical joints, the flutings being inside and outside of the plates, the shellplates being fluted in same manner, but on the outside only, the water side being plain. In cylindrical multitubular boilers we flute the plates of furnaces longitudinally and the small tubes also inside and out, and the lat ter we secure to the tube-plates by the same method as we use for the inner tube of the water-tube boiler, with the exception of the brass plug, the copper ring being pressed against the walls of holes in tube-plate direct. I11 steam-condensers we use the. same arrangement of fiuted tubes, one inside the other, and both joined and secured to rectangular boxes, as in the water-tube boiler, and both tubes being fluted inside and out, the exhaust-steam passing into the boxes or headers and the space between the outer and inner tubes, and the condensing water surrounding the outer tube and passing through the inner tube, and this combination being inclosed in a water-tight casing.
The accompanying drawings will serve to illustrate the foregoing statement, wl1erein- Figure 1 is a side elevation of a water-tube boiler, Where A A are headers; B B B, the tubes; 0, the steam receiver; 0, the furnace, and G the casing. Fig. 2 is an end elevation of same, where similar letters refer to the same parts as in Fig. 1. Fig. 3 shows section of outer and inner tube with fiutings. Fig. 4 is a longitudinal section of portion of header and outer and inner tube and manner of securing same to header, where A is header; B B, the tubes; D, the brass plug; D, the tapered hollow plug, and D the copper washer. Fig. 5 is an elevation of a steam- O0I1d6l1S6],Wh(-}I6 A A are the headers; B B B, the tubes; E, the outer casing, and F F the steam and water pipes. Fig. 6 is an end elevation of condenser, where similar letters refer to similar parts as in Fig. 5.
Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is
1. The combination, with a header-plate, of an external tubular plug secured in a hole in the said plate, a tube B having a conical end, an internal tubular plug having a con- .ical portion and screwed into the tube B, and
a metallic packing-ring fitting inside the said external plug and bearing against the conical portions of the said tube and internal plug, said conical portions being inclined in opposite directions,substantially as described and shown.
2. The combination, with a hollow header having two tube-plates, of an outer tubeB secured into one of the said plates, an external tubular plug secured inahole in the other said plate, which hole is large enough for the tube B to pass through, a tube i arranged inside the tube B and having a conical end, an internal tubular plug having a conical portion and screwed into the tube B, and a metallic packing-ring fitting inside the said external plug and bearing against the conical portions of the said tube and internal plug, substantially as described and shown.
In testimony whereof we affix our signatures in presence of two witnesses.
