LOGOMOTIVE BOILER.
. Patented Sept. 7, 1886.
UNITED STATES PATENT ()rrlcn.
VALTER DAVSON, OF SGRAN'ION, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO \VILLIAM F. HALLSTEAD, OF SAME PLACE.
LOCOMOTlVE-BOILER.
SPECIFICATION forming pan: of Letters Patent No. 348,831, dated September '7, 1886.
Application filed June 8, 1886. Serial No. 204,500. (No model.)
To all whom it may concern:
Be it known that I, TALTER Dawson, of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Locomotive or, other Boilers, of which the following is a specification, reference being had to the aceompanyin g drawings,and to the letters of reference marked thereon.
The object of my invention is to construct a boiler specially adapted to burn pulverized fuel, waste coal, culm, &c., although other fuel may be used to advantage, the invention consisting in the construction, combination, I 5 and arrangement of parts, as hereinafter claimed.
In the accompanying drawings, Figure 1 is a front View, partly in section, of a locomotive-boiler embodying my improvements. Fig. 2 is a longitudinal section of the same.
Similar letters of reference indicate similar parts in both figures.
A is the shell or waist of the boiler. represent tubes such as are ordinarily used in boilers of this class.
C is the fire-box, and D its tube-sheet. E represents a tubular grate connecting the front and rear water-spaces of the furnace.
F F represent the lower series of tubes. 0 Theinner or furnace ends of said series oftubes unite with the tube-sheet D, the said tubes having here the same diameter as have the tubes B-say two inches. The opposite end of each tube F, where it connects with the for- 5 ward tube-sheet, D, asiudeed the entire length of the tube, except at the point of its connection with the furnace tube-sheet, is enlarged to a diameter of, say, four inches. The object of this construction is threefold, first, to provide a space, as from a to a, for the fuel; sec 0 ondly, to produce a wide or enlarged space, b, through which an unobstructed and sufficient circulation of water may pass, and thus pro tect the boiler at a point exposed to a high degree of heat; and, thirdly, to bring the tube- 5 surface in as close proximity to the lower portion of the shell or waist of the boiler as is practicable, and thus effectually heat the wa t-er occupying said part of the shell.
In boilers as ordinarily constructed there is a large space at the bottom of the waist or shell, which contains water comparatively cold, because the tube-surface does not extend into it. Consequently no heat is imparted to a large bodyofwater. By myimprovementthis body of water is effectually heated, the steaming qualities ofthe boiler being improved, and its durability increased, owing to the production of a uniform temperature.
Having described my invention, I claim In a locomotive or other boiler, the combi' nation, with a shell, furnace-grate, and tube sheets D D, of a tube, (or series of tubes,)F, arranged throughout the greater part of its length in close proximity to the shell, and of reduced diameter or size where it connects with the tube-sheet D, substantially as set forth.
In testimony whereof I have hereunto set my hand and seal.
