DAVID RENSHAVV, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN SECTIONAL STEAMGENERATORIS.
Specification forming part of Letters Patent No. 143,843, dated October 21, 1873; application filed February 4, 1873.
A To all whom it may concern:
Be it known that I, DAVID ItENsHAW, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Generators; and I do hereby declare with a reverberatory furnace, said furnace be-` ing made of brick or other similar substance possessing `great capacity for the retention and return of heat, or of hollow cast-metal sections, designed not only to reverberate heat upon internal generators, but to contain water and generate steam. rihis invention consists mainly in the peculiar construction of the internal generators, consisting each of a continuous curved pipe, having, if desired, inner arches, and in the combination of said generators with a reverberatory furnace and a steam-drum connected therewith, as hereinafter fully described.
Referring to the drawing, A shows a reverberatory furnace, constructed as described, surmounted by a steam-drum, B. C is the grate, which is equal in area to the base of Vthe furnace, and c c are iiues extending from the front to the rear of thefurnace. The doors are shown at D. E is a pipe or tubular water chamber running longitudinally through the furnace, having supports in the front and rear walls thereof. The pipe E has iianged projections e, forming connections with the sections F, which have similar projections j' and f1, the latter connnunicating,as seen,
. with the drum B. The sections F consist of the outer continuous pipes F1 and the inner arched pipes F2, the inner and outer pipes being all cast at once and in a single piece.. In order to facilitate the removal of the cores in casting, and to provide for easy accessto the inside of the generators, they are formed with. open projections at f3, said projections being formed with suitable caps. For the purpose of obtaining a downwardcirculation in the outer pipe, and an upward circulation in the inner pipes, the former are made of greater diametrical dimensions than the latter, thus holding a greater amount of water to a proportionately less amount of iire surface, and thereby producing the result desired. b b are gage-cocks on the steam-drum. A feedpipe is provided at d, and a blowoff pipe is seen at d.
A steam-generator thus constructed possesses many important advantages. The castings are easily made, and, as the sections are all cast in one piece, economy is secured. The outer portions of the sections holding larger water bodies than the inner portions, the desired upward and downward circulation is secured. Due provision is also made for the equalization of the contraction and expansion of the metal, as it is obvious that, as both the inner and outer parts of the sections from point to point of their connections are arches of about the same length, the expansion and contraction will be nearly equal in both.
What I claim as my invention is l. The internal section E, formed of a conA tinuous curved pipe with inner arches F2, as described, said arches being of less diametrical dimensions than the pipe E, so as to produce circulation, as specified.
2. In a reverberatory furnace, the combination of the sections F, formed of a continuous curved pipe, made with the inner arches F2, the tubular waterchamber E, and steamydrum B, substantially as shown.
In testimony that I claim the foregoing I have hereunto set my hand this 22d day of January, 1873.
DAVID RENSIIAV.
