VERTICAL STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 708,729, dated September 9, 1902. Application filed August 19, 1901- Serial No. 7254A. (No model.)
To allwhom it may concern:
Be it known that I, WILLIAM PENMAN, a citizen of the United Kingdom of Great Britain and Ireland,residing at Springfield House, Springfield road, Glasgow, Scotland, have invented certain new and useful Improvements in Vertical Steam-Boilers, (for which application for patent has been made in Great Britain, No. 1,815, dated January 26, 1901,) of which the following is a specification.
This invention has for its object to provide a vertical steam-boiler of improved construction wherein great heating-surface and rapid and complete circulation are obtained by means of inclined cross-tubes connecting opposite sides of the annular water-space surrounding the furnace. l
The invention is illustrated by theaccolnpanying drawings, in which Figures 1 and 2 are vertical sections at right angles to each other of a vertical boiler constructed in accordance with my invention.
The improved boiler comprises an outer shell A and an inner shell B, united in the usual way at the base and at the domed top around a central chimney-outlet'O. The inner cylindrical shell B is pressed or dished at various points or has cut in it a number. of upper and lower openings D, around each of which is attached, by riveting, an inwardly dished or pressed plate E, having by preference an inclined fiat surface, the dished plates E at top and bottom being oppositely inclined and arranged in pairs diametrically opposite each other; Into orifices in the opposite dished plates E water-tubes F are expanded, the tubes F being preferably straight and entering the orifices at right angles to the dished plates, though they may be curved or bent, and these tubes F extendfrom the lower dished plates E on either side to the upper dished plates E on the opposite side of the boiler. Thetubes F, connecting the uppe-r and lower dished plates E, thus cross each other after the fashion of the letter X; but additional rows of tubes G may extend horizontally, or nearly so, across the boiler above the inclined rows F. The fire-grate H is fitpanding them into their orifices and for cutting them out.
Having now described the invention, what I claim, and desire to secure by Letters Patent, is
1. A- vertical steam-boiler comprising the usual outer shell, in combination with an inner shell formed with dished portions arranged in pairs opposite each other, one of each pair being in proximity to the fire-grate and the other to the furnace-crown,cross-rows of inclined tubesexpanded into these dished portions approximately at right angles to the dished surfaces, and additional rows of tubes extending horizontally across the boiler above said inclined rows of tubes and orifices in the outer shell ooveredby doors substantially as described.
2. The herein -described vertical steamboiler comprising in combination with an outer shell an inner cylindrical shell formed with dished portions diametrically opposite each other, cross-clusters of inclined tubes expanded into said dished portions, the outer shell having orifices opposite said dished portions closed by doors, substantially as and for the purpose set forth.
3. The herein-described vertical steamboiler comprising in combination with an outer shell an inner cylindrical shell formed with orifices diametrically opposite each other,'dished plates riveted to the inner shell WILLIAM PENMAN.
