: This invention relates to an improvedboiler 'designed'and intended to generate steam or heat water fordomestic or commercial use, or for any other purposes wherein it is found to be applicable.
The invention contemplates among its important objects and advantages to provide. a boiler of the character described, which embodies a novel highly eificient and-compact coil assembly operable for quickly heating water, which includes a preheating mechanism for heating the water prior to its entry into the coil assembly,
which will expedite steam generating or water heating operations on a minimum fuel consumption, which is simple in its construction and arrangement, durable and highly efficient in its use, attractive in appearance, compact, and comparatively economical in its manufacture, installation, operation, and maintenance.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the novel construction, combination, and arrangement of parts herein specifically described and illustrated in the accompanying drawing, but it is to be understood that the latter is merely illustrative of an embodiment of the invention, and that the actual needs of practice and manufacture mayrequire certain mechanical variations from the embodiment shown. It is, therefore, not intended to limit the invention to the disclosure thereof "herein illustrated, but rather to define such limitations in the scopeof the claims hereunto appended.
In the drawings wherein like numerals of reference designate corresponding parts throughout the several views:
Figure 1 is a vertical cross sectional view of a boiler constructed in accordance with the invention.
Figure 2 is a top plan view of the water preheating barrel and of the associated burner.
Figure 3 is a similar view of the coil assembly.
Figure 4 is a side elevational view of the coil assembly.
Figure 5 is a transverse cross sectional view of the coil support.
Referring in detail to the drawings l denotes an insulated boiler casing, which may be of any suitable construction and contour. The lower portion of the interior of the boiler casing procompartment 2 is a gas burner 4 of any suitable construction, which joins with the source of the fuel supply in'the usual manner.
A water preheating barrel 5, having a diameter somewhat lessthan the diameter of the furnace compartment 2, is mounted and suitably sup ported in the latter. The preheating barrel comprises a tubular base ring 6, which surrounds the burner '4 and is connected with the cold water supply pipe 1.
Four similar upright conduits 8 are mounted on the base ring 6. The conduits 8 are arranged and spaced in diametrically opposed pairs, and
have their lower ends communicably joined with the base ring.
A plurality of horizontally extending, bowed tube sections 9 is connected with each adjacent pair of conduits B. The tube .sections are disposed parallel in slightly spaced relation to each other, and communicate with respective conduits 8.
A coil assembly [0, which is the most important feature of the invention, is mounted in the coil compartment 3 of the boilercasing I, and may be supported on the top of the preheating barrel 5, as shown, or may be secured in position in any other suitable manner. The coil assembly is spaced from the top of the coil compartment to provide a draft chamber, with which latter a suitable flue l I is joined for the obvious purpose of dissipating the products of combustion during the operation of the boiler.
The coil assembly In includes a coil supporting spool 12, which latter consists of the tubular joined top arms l3, and the similar bottom arms I4. The top arms l3 are four innumber and are joined together at their inner ends to form a cross. The toparms l3 extend radially horizontal with each of said arms 13 being disposed at right angles with respect to the adjacent top arms l3. The said arms have closed outer ends, and
the joined inner ends thereof are interco-mmuni-- eating. The bottom arms [4 are identical in arrangement to said top arms l3, and extend parallel relatively to the latter.
Five vertically disposed tubes, respectively indicated at 15 and I6, are communicably joined with respective top and bottom arms 13 and I4, and serve to hold the latter in the properly spaced relation to each other. The center tube [5 connects with the centers of the joined inner ends of said arms l3 and I4, and each of the tubes I6 is positioned adjacent and parallel to said center tube l5, and connects with a different top arm [3 and with the corresponding bottom arm I4.
The upper end of each of the upright conduits 8, of the preheating barrel 5, is communicably joined with the underside of the free end of respective bottom arms 14, whereby the coil assembly I is supported on top of the preheating barrel, and of course, is in communication with the latter.
The coil assembly I0 comprises sixteen separate spiral coils, which are arranged in four series of coils, respectively indicated at I], 18, I9, and 20, and with each of the latter consisting of four separate'sets of coils, respectively indicated at 2|, 22, 23, and 24. Each coil series I1, IS, IS, and 20, varies in diameter with respect to the coils of other series, but the diameters of the coils of a set of coils 2|, 22, 23, and 24 in any one series are uniform relatively to each other.
The coil series l1, l8, I9, and 20 all, surround the tubes I5 and I6, and are arranged concentrically in spaced relation to each other. series I! is disposed outwardly in the coil group,
The coil and the coil series 18 is disposed inwardly of and next to the former. The coil series I9 is positioned inwardly-of the coil series "Land the inher coil series 20 is disposed inward y of the coil series IS.
The upper terminus of each tubular coil of each coil set 2|, 22, 23, and 24 is connected with a different upper arm l3, and the lower end thereof connects with the different respective corresponding lower arms I4. Each coil of each coil set has three full convolutions, and all of the coils in any coilset are spirally parallel to each other, giving each of the coil sets the general appearance of being a single coil of continuous length. The purpose of employing four separate coils in each coil set is to give the coils a greater pitch to thereby accelerate the flow of :water or steam therethrough in either direction, whereby the efficiency of the coil assembly is greatly enhanced.
The spirals in the coil sets in the coil series I! and 19 extend from top to bottom in the counterclockwise direction, while the spirals in the coil sets of the coil series 18 and 20 extend in the clockwise direction' This alternation of the coil direction greatly facilitates the assembly of the coil assembly by affording greater clearances, and further allows the ready .and convenient removal or replacement of any single coil of the structure without disturbing any others of the embodied coils.
An outlet conduit 25-c0nnects with the top center of the joined inner ends of the upper arms 13 of the coil assembly 1.0 for conveying or distributing the heated fluid from the boiler to the various places of consumption-for the purposes required and employed.
A water level gauge 26 is positioned for visible observation at the outer side of the boiler casing I, and connects with the free outer end of an upper arm 13 of the coil assembly Ill and with the outer end of the corresponding lower arm I4. The
boiler is provided with a pressure gauge 2! and a safety valve 28, which connect with an upper arm l3 and are preferably positioned on the top of the boiler casing I.
If the improved boiler is used for generating steam, a conduit 29 'is provided. to connect with the free outer end of one of the upper arms I3 of the coil assembly 10 and with the base ring 6 of the preheating barrel 5. The conduit 29 carries connections 30 for joining a suitable water level control therewith for regulating the water level in the boiler.
In the operation of the improved boiler the water will be preheated in its travel through the preheating barrel 5 by means of otherwise wasted heatfrom the burner 4, as said barrel 5 surrounds the latter and is confined within the furnace compartment 2.
The preheated water from the preheating barrel 5 passes from the latter through the upright conduits 8 into the coil assembly In, wherein it is quickly heated to the desired temperature. Extensive experiments have shown that steam is generated in a few minutes and maintained at constant pressure during continuous use.
The present invention provides a most compact and efiicient device of its kind, which may be economically and successfullyemployed for the purposes and in the manner herein set forth.
