SPECIFICATION forming part of Letters Patent No. 632,198, dated August 29, 1899.
Application filed September 2'7, 1898. Serial No. 692,023. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM PENMAN, boiler-maker, a subject of the Queen of Great Britain and Ireland, and a resident of Glasgow, Scotland, have invented certain new and useful Improvements in and Relating to Vater-Tube Boilers, of which the following is a specification.
This invention has reference to improvements in and relating to water-tube boilers and comprises a method of isolating the boiler in sections and an improved combination of parts, and in order that others skilled in the art to which my invention relates may under-' stand how same may be carried into practice I have hereunto appended explanatory drawings, in which- Figure 1 is a longitudinal section of a Water-tube boiler as fitted with my improvements, while Figs. 2 and 3 represent transverse sections of same as looking at the left and right hand ends, respectively.
Referring to the drawings, according to my improvements I use three drumsan upper steam-generating drum A and two parallel lower drums B O-with dished-out ends. The tubes X, connecting the lower drums B B and C 0, thus constituting separate water-tube sections, are preferably set at an angle and expanded into tube-plates, such as B, in chambers at their ends, and portable doors, such as B are fitted on both chambers for easy access of removing and renewing tubes.
The top and bottom drums are connected by a series of short preferably-curved tubes D expanded into these drums, and a number of which may be stay-tubes, or these drums may be joined together by riveted steel tubes, as desired. In the larger class of boilers the back end of lower drums B C may have a manhole-door, so as to get access through it to expand the tubes instead of requiring to remove the main door. The tubes may be put in from front of boiler, and in the event of any of the tubes giving way they can easily be replaced, or in the event of any section giving out the tubes in that section can be stopped by means of an inside-Valve arrangement, such as a lift-Valve E in a seat-chamber E covering all the top ends of tubes D in upper drum A and operated by a spindle E and hand-wheel E from outside of drum,
stiffening larger tubes F on each section and each fitted with a valve at F. With this arremoving the casing or the brickwork. The
need of skilled labor. A mud-drum G will ber of the sections B-O. The boiler can be transport.
rangement of the boiler would be similar:
I claim as my invention steam-drum, connections between the drum the drum to operate said valve, all arranged above the fire, substantially as described.
2. A water-tube boiler having a steamdrum, two or more sets of water-tubes constituting water-tube sections, chambers in J in the steam-drum adapted to close communication between the drum'and any set of watertubes desired, substantially as described.
3. A watertube boiler having a steamdrum adapted to close communication between the connecting-tubes and drum, a cirstantially as set forth.
