WATER-HEATER.
Specification of Letters Patent.
Patented Aug. 10, 1915.
Application filed December as, 1914. Serial in. 879,417.
To all whom it may concern:
Be it known that I, ARTHUR L. GAssnTT, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Water-Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
This invention relates to that class of water heaters which comprise double wall casings and between the walls whereof water is adapted to be circulated in a comparatively thin body and subjected to the influence of a heating device, such as a gas burner, that is arranged to discharge its heat, or products of combustion, into the casing.
My invention has for its object the-provision of a water heater of the above nature that is extremely eiiicient; that can be readily cleaned; that may be very easily assembled and dis-assembled; that may be manufactured in various sizes and capacities by means of the same equipment; wherein the heating device or burner is supported in such manner as to insure the proper location thereof, with respect to the casing, and
facilitate its removal therefrom; and wherein provision is made for the liberation of undue internal pressure resulting from an explosion of accumulated gas within the casing, thereby relieving the casing of the shock or strain which would otherwise be caused by such an explosion.
The foregoing objects, and others which will become apparent as this description proceeds, are attained in a water heater constructed in accordance with the accompany ing drawings, wherein Figure 1 is a perspective view of the water heater; Fig. 2 is a central vertical section thereof; Fig. 3 is a perspective of the burner casing; Fig. l is a similar view of one of the drum sections; and Fig. 5 isa sectional detail on line 55 of Fig. 2.
The water heater is supported upon a pedestal comprising a foot or base 1 from which rises a post 2, which post may consist of a tube, and the upper end of the post is threaded for the reception of the boss 8 of an elbow 4. A water supply pipe 5 is threaded into the lateral branch of this elbow, and the lower end of what I willterm the ingress pipe 6 is threaded in the vertically disposed branch thereof. Applied to the threaded, upper end of the ingress pipe is the lowest of a series of drum sections, the same being designated 7.
V Thedrum section just referred to comprises a cylindrical wall, to which the reference numeral 7 is applied, and the upper edge' of such wall is ground, or otherwise treated, to produce a frusto conical extension 8, while the opposite or lower edge of said wall is provided with a tapered seat 9, of the same inclination as the frusto conical portion 8. A conduit 10 extends diametrically across the drum section and opens through its cylindrical wall and a boss 11 depends from the central portion of the conduit 10 and is internally threaded for the reception of the threaded upper end of the ingress pipe, as above described.
Superimposed upon the lower drum section 7 area number of what I will refer to hereinafter as intermediate drum sections 15, each comprising a cylindrical wall, to
which the numeral 15 is applied, and a diametrically disposed conduit 16, similar to the conduit 10 of the section 7, the same opening at each end through the wall 15. Projecting at substantially right angles from the outer surface of the wall 15, and in substantially the plane of the conduit 16, is a baffle 17 the same being shown clearly in Fig. 4 wherein it will be seen that the baffie is interrupted at the point where the conduit 16 opens through the wall of the drum section. The upper edge of each of the intermediate sections is formed with a frusto conlcal extension 18, while its lower edge is provided with a similarly shaped seat 19;
F ittinguponthe conical extension 18 of the top lntermediate section, is the tapered seat 20 of the vertical wall 21 of the uppermost drum section of the series. A conduit 22 extends diametrlcally across its section and opens at its end through the wall 21, and rising from the conduit is a boss 23 that is the base ring having a frusto-conical extension 33 arranged to be received by the tapered seat 9 of said drum section.
It will thus be seen that a drum is formed by assembling the various sections as above described, and binding them firmly together by means of the tie rods 26, the interfitting edges of the adjacent parts providing watertight joints, and, if found desirable, some sort of sealing material, such as white lead, may be used between the interfitting edges to insure such joints against leakage.
From Fig. 2 it will be observed that the base ring 31 (with its horizontal portion to which the reference numeral 31 is applied, its frusto conical extension 33, and its vertical flange 34 that is spaced from and substantially parallel with the extension 33) is of channel formation and is arranged to receive the lower edge of a shell or casing 35, preferably formed of sheet metal. A ring of packing material 36 is firmly compressed between the outer surface of the shell 35, adjacent its lower edge, and the opposed Wall of the vertical flange 34 of the base ring 31, by a gland ring 37, which is adapted to be drawn downward by cap screws 38 which pass freely through ears 39 that extend radially from the ring 37 and are threaded into similar cars 40 of the base ring. By this means a water-tight joint is formed between the lower end of the shell 35 and the base ring 31. Adjacent its opposite end, the shell 35 is provided with an internal shoulder 43, the same being preferably formed by pressing the material of the shell inward; and a ring of packing material 4-4 is wedged be tween said shoulder and the opposed wall of the upper drum section by means of a follower or gland ring 45 that is engaged and forced downward by a top or cap 46, said cap or tophaving a substantially horizontal portion 47 for cotiperation with the upper edge of said ring. This cap is also provided with a depending peripheral flange 48 which embraces the upper end of the shell 35, and within the boundary of its horizontal portion, the cap 46 is curved upward into a dome that terminates in a vertical collar 49.
Surmounting the cap 46 is a cupola 50, the lower edge of which fits over the collar 49 of the cap. To a lateral outlet extension 51 of the cupola is applied the end of a flue pipe 52, and substantially central of the cupola,
its upper wall is provided with an aperture 53, through which the egress pipe 24 passes. It will be observed, particularly from Fig. 1 that the horizontal portion 47 of the cap 46 cuts into the dome shaped portion thereof at points about its circumference, to provide recesses for the accommodation of nuts 55 that are applied to the upper ends of the tie rods 26, and by means of which the cap may be drawn down into firm contact with the gland ring 45 and cause said ring to wedge the packing material into engagement with the opposed walls of the shell and drum, thereby to form an effective water-tight joint.
The burner casing, shown in detail in Fig.
3, is suspended from and attached to the lugs 61 that depend from the under side of the base ring 31, by means of cotter pins 62, which pass through the alining apertures of the casing and said lugs. The casing comprises a cylindrical portion 63, from the lower edge of which is spaced and suspended a basin 64, by means of the strap 65, all of such parts being preferably formed of an integral casting. It will be observed from Figs. 2 and 3, that the apertures 66 in the basin 64 are surrounded by upwardly extending beads, as is also the notch 67 which extends inward from the periphery of the basin, to slightly beyond the center thereof. This notch makes it possible to apply the burner casing to the water heaterafter the same has been assembled, without having to disturb the inlet connection. Because of the presence of the aforesaid beads, any water which may accumulate within the basin 64 by reason of condensation, will be prevented from dripping through the apertures 66 or notch 67 thereof, and will be evaporated by the heat of the burner. It will be noted that a segment of the cylindrical portion 63 of the casing is hinged at 69, to the stationary portion thereof, to form a door 68, the same being provided with a spring latch 70 for cotiperation with a keeper 71 that extends from the side of the casing. Because of the nature of this latch, the door 68 may very easily be opened by excessive internal pressure such as might be caused by the explosion of gas within the casing.
A gas burner is shown at 75, (in Fig. 2) as located within the casing 60, and said burner is formed so as to straddle the ingress pipe 6 and be removable laterally therefrom; and depending from the burner is a boss 76 which receives the upper end of a tube 77 of a mixer 78. As shown in detail in Fig. 5, a wing 79 extends from each side of the boss 76, and these wings are arranged to be received by recesses 80 that open from the opposite sides of the notch 76 and are formed in depending bosses 81 of the basin 64. In this manner the burner is supported in an upright, horizontal position and in proper alinement with the drum of the heater. It will be mentioned that the wings 79 of the burner are tapered, and that the recesses which receive them are similarly shaped, to facilitate removal of the burner.
A gas valve 8:2 is supported by the bracket 83, from the post and has connection at its upper end with the mixer 78. The lower end of the valve is connected to the gas supply pipe 84.
When water is turned into the supply pipe 5, it rises through the ingress pipe into the conduit 10 and flows in both directions to the space between the shell 25 and the opposed wall of the drum. Rising within said space, it is distributed in a thin body throughout the casingand within the various conduits l6 and 22, from the upper of which it finds its way to the egress plpe 24. The products of combustion from the burner 7 5 rise within the drum and circulate about the conduits 10, 16 and 22, finally escaping through the cupola and flue pipe. The water in the heater, and especially that within the conduits of the drum, is quickly heated; and to cause it to take a rather tortuous course as it rises through the heater, adjacent drum sections are turned with their respective conduits at right angles to each other, and this arrangement places the openings in the baiiies 17, 90 apart about the circumference of the drum. Because of this the water rises from the open ends of the inlet conduit 10 until it is defiected by the first of the baffles 17 to the vicinity of the open ends of the conduit 16 of the lowest intermediate drum section. From here it rises to the elevation of the next baffle 17, where it is again deflected laterally to the region of ends of the conduit of the second intermediate section, and so on to the top of the heater. Also the products of combustion are caused to traverse a more or less tortuous course about the conduits of the drum.
When it is desired to clean the heater of sediment which shall have accumulated therein, such may be easily accomplished by simply removing the flue pipe from the cupola and the nuts 55 from the upper ends of the tie rods 26. Now by sliding the cupola and the cap 46, together with the gland ring 45 upward along the egress pipe, the shell 35 may be entirely removed from the drum, and the exterior of the drum thoroughly scrubbed and the conduits cleaned out.
While the very substantial construction of the heater would enable it to Withstand an explosion of a quantity of gas equal to the capacity of its combustion chamber, means are provided for liberating excessive internal pressure that might be caused by an explosion of such gas, by making a portion of the burner casing removable, as previ ously set forth. Upon the accumulation of gas within the casing, which might result from the burner being put out, and -a subsequent lighting thereof, the force of the explosion will open the doors 68, the catch of the door being of such nature, as hereinbefore described, as to allow of such action. Furthermore, if it is desired to remove the burner. for any reason, the door 68 may be opened and the burner elevated to withdraw its wing portions 79 from the recesses 80 when the burner may be lifted out of its casing and away from the ingress pipe 60, it being understood that the mixer 78 has a slip joint connection with the valve 80, according to usual practice.
I have hereinbefore made mention of the fact that the size or capacity of my heater may be increased without increasing the cost of its manufacture, for the reason that no extra equipment is necessary for making the heater in various sizes or capacities. Therefore, if a heater of greater capacity than that shown in the drawings should be desired, it may be obtained by inserting any number of the intermediate drum sections, increasing the length of the shell 85 to correspond to the increase in the length of the drum, and likewise lengthening the tie rods 26. The only additional cost in the production of larger heaters is, therefore, that of the additional material required, for the larger heater requires no more work in assembling.
While I have shown in the accompanying drawings a very practical embodiment of my invention, the construction shown therein is to be understood to be illustrative only, and not as defining the limits of my invention.
Having thus described my invention, what I claim is:
1. In a water heater, the combination of a shell, a drum comprising a series of superimposed sections fitted together to form a wall that is spaced from the shell, the section at one end of the series having an inlet and the one at the opposite end an outlet connection, sealing means between the ends of the drum and shell, and a heating device located in operative relation to the drum and shell.
