RANGE BOILER Filed June 24, 1942 2 Sheets-Sheet 2 /IIIIIIIIIIIIIIIIIIIIIIII-III,
[nveno-r- MM Mm Patented Jan. 2, 1945 UKJLLI bl] UNITED STATES PATENT OFFICE 3 Claims.
My invention relates to range boilers, and its principal object is to provide a, boiler which embodies a new and improved circulating principle, whereby it is capable of producing hot water more quickly and in larger quantities than is possible with boilers of ordinary construction having the same general dimensions.
A further object of my said invention is to provide means for rapidly and effectively cleaning out the coil and other parts of the boiler. This is considered of great importance at the present time, when coils and other parts ordinarily made of copper or brass must be replaced by iron or steel which are much more liable to corrosion and scaling, so that more frequent cleaning of the parts is necessary.
Another object is to provide a simpler and less expensive supporting means forthe boiler, whereby it is more easily installed and at the same time the floor space adjacent the boiler is more accessible for cleaning purposes.
With these and other objects in view, I will now describe a preferred embodiment of my invention with reference to the accompanying drawings, in which Figure l is a, diagrammatic elevational view of the range boiler showing the location of the principal parts.
Figure 2 is a fragmentary vertical section of the boiler drawn to an enlarged scale showing the complete details, certain parts being shown in elevation for the sake of clearness.
Figure 3 is a fragmentary horizontal section taken on line 33 of Figure 2, and
Figure 4 is a fragmentary vertical section I taken on line 4-4 of Figure 2 illustrating the rearrangement of certain parts in order to facilitate cleaning of the coil and adjacent passages.
Like characters designate corresponding parts throughout the several views.
In the drawings, I is the main casing having a cover II secured thereto by welding and a bottom I2 also welded to the main casing. The casing I extends below the bottom as shown at IA to form a heater chamber, and this chamber is provided with a removable closure I3 as shown. In the cover II is an opening connected by a union with the hot water pipe I4 and another union to which is connected a cold water pipe I5, the pipe I5 having a downwardly extending portion I5A of conventional construction reaching to within a short distance of the bottom I2 as shown. In the center of the bottom I2 is welded a socket I2I which is internally threaded to receive the upper end of the coil assembly to be hereinafter described, and extending upwards from this socket is a pipe I22 which reaches within a short distance of the cover II. The pipe I22 has two or more openings I23 communicating with the main chamber of the heater.
The heater assembly consists of a coil 2 of metal tubing arranged in spiral form having a central tubular member 3, the upper end of which screws into the socket I2I while the lower end extends downwardly through the lower cover I3 and has a solid end 3I adjacent to which is a drain valve 40, normally closed. Intermediate the drain valve 40 and the coil 2 is arranged a partition 32 by which the tubular member is divided into two separate passages 33. 34, and the outer terminal 2| of the coil is connected by welding or otherwise with the passage 33. Above the coil 2 the tubular member 3 is again divided by a partition 35 into two passages 36 and 31, and the inner terminal 22 of the coil 2 is connected by welding or otherwise to the passage 36, while the passage 31 merely forms a continuation of the passage 34 below it. Within the passage 36 and forming a continuation thereof is a relatively small pipe 38 which extends upwardly within the larger pipe I22 near to or level with the top thereof. Within the heater chamber and below the coil 2 is a gas burner 4 spaced vertically from the coil and having the usual openings 4| in its upper surface, and to the bottom of this burner is connected a mixing tube 42 having a conical bottom 43 into which projects the gas jet 44, the latter being fed from the gas pipe 45 through the usual shut-off cook 46, the complete burner following the conventional construction and having its main portion extending more or less around the underside of the coil. It will be observed that the tubular member 42 is secured within an opening in the cover I3, while the cover itself is secured upon the tubular member 3 as by set screws I3l. An opening I8 in the casing having a, swing ng cover I1 facilitates the lighting of the burner, while on the opposite side of the casing is a flue opening I8 provided with a laterally projecting socket I9 adapted to receive the usual flue pipe carrying away burned gases from the heater chamber. In the lower part of the tubular member 3 and in opposed relation to the drain valve 40 is a threaded opening 39 and into this opening is screwed a plug 5 having a hexagonal portion 5| for manipulation by a wrench, and outwardly of this is a. threaded portion 52 and a solid cylindrical portion 53 for a purpose to be hereinafter explained.
In order to support. the heater in a simple manner, there is provided a circular base 6 into which is welded a central pipe 6| which extends downwardly to the floor line as shown in Figure 2, and at its upper end receives the solid portion 3| of the tubular member 3, the whole forming a simple and inexpensive pedestal which takes the place of the usual support having three or four legs and renders much easier the cleaning of the floor which surrounds the heater.
In operation, the boiler being filled with cold water through the pipes l5 and ISA and the burner lighted, the water flows downwardly through the passage 31 into the passage 34 and then around the partition 32 as indicated by the arrow .1: in Figure 2, whence it continues onwards through the passage 33 into the outer portion 2| of the coil. The water thus being heated flows upwardly through the passage 36 and the pipe 38 to the upper portion of the boiler. It will be noted that the pipe 38 is, to some extent, isolated from the main body of the cold water by the pipe I22 so that the heated water reaches the upper portion of the boiler with very little lose of heat, by which arrangement hot Water is almost immediately available for discharge through the pipe I4. In the meantime, the small amount of water contained in the pipe I22 becomes heated from contact with the smaller pipe 38 and then, by continued circulation, the whole body of water within the boiler comes to the required maximum temperature. The advantage of the preliminary discharge of hot water through the pipe 38 is read ily seen since it provides a small quantity of hot water for immediate use, and it is found that the entire body of water becomes heated in a much shorter time than is possible with boilers of ordinary construction.
It has been pointed out in the preamble of this specification that, due to the great demand for copper for war purposes, it is necessary to construct the coil 2 from steel or iron tubing which is much more subject to corrosion and scaling than is the case with copper. In order to facilitate the cleaning out of the coil and the adjacent portions of the heater assembly, the plug 5 is removed from the position in which it is shown in Figure 2 and is reversed, as shown in Figure 4, so that its cylindrical portion 53 projects into the passage 34, thereby closing it. The water supply is then turned on so that the pressure from the water main is applied to the body of water within the boiler, which is thus forced downwards through the coil and through the passage 33 to the open drain valve 40 as indicated by the arrow y in Figure 4, which results in quick and thorough cleaning of the coil.
It will be observed from the foregoing description and by reference to the drawings that I have provided a range boiler in which the production of hot water is much more rapid than is the case with existing boilers, and also a method of quickly and easily cleaning out the coil and adjacent parts, as well as an improved supporting means for the boiler as a whole. It will be readily understood by those skilled in the art to which my invention pertains that various changes in detail may be made to suit any particular or peculiar requirement without departing from the spirit of the invention as defined in the appended claims.
Having thus described my said invention, what I claim and desire to secure by Letters Patent of the United States is:
