HATER-HEATER AND STEAM-GENERATOR.
Specification of Letters Patent.
Patented Dec. 26, 1911.
Application filed June 23, 1910.- Serial No. 568,580.
spiral course, in which the heat generated shall be utilized to the highest efliciency and which will enable access to the water passages for the perfect and easy removal of sediment, or other obstructions, therefrom; and to this end my invention consists in the apparatus constructed substantially as hereinafter specified and claimed.
In the drawings, Figure 1 is a vertical section of an apparatus embodying my invention; and Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.
In the embodimentof my invention shown in the drawings, the heat is supplied from a series of gas burners 10, each of which projects through an opening in the side of a casing 11, which is completely closed so as to have no communication with the external air, so that it is air-tight and all air is 6X- cluded except through the air-mixing burner. Thus, there is no u'ndue draft through the casing which results in heat being carried up through the chimney before it is fully utilized. lVithin the casing is a vertical series of heating members or units each composed of two disks, one 12, which has in its surface a tortuous passage or channel 13 of spiral form that is formed by a shallow groove that has a fiat bottom, the outer end of the spiral being in communication with a water inlet pipe 14: and the inner end of the spiral being in communication with a water outlet pipe 15. The other disk 16 is simply a Flat plate applied to the open side of the groove 13, so as to complete the four sides of the groove, and the two plates are detachably connected together, as by screws or bolts 17, so that the cover plate 16 can he removed whenever desired to give access to the groove 13 for the removal of sediment, etc- Obviously the construction is,,an inexpensive one, since only one disk need be provided with the spiral groove, the other being a simple plate with plane surfaces. Yet by reason of the flat form of the channel, a film of water of ride uate extent issubjected to heat at top and ottom and at both sides, so that the raising of the water to the desired temperature is quickly and, therefore, economically effected. There are no holes vertically through the. two combined plates 12 and 16 of a unit, and thus no heat is lost by passingdirectly through a unit from top to bottonnand the only vertical passage-way for the heat is between the circumference of each unit and the side of the water jacket.
The spiral groove instead of being of the form shown in Fig. 2, may be a regular spiral of ordinary form.
An important characteristic of my apparatus is the absence of such conditions within the casing 11 as result in back-draft, or the precipitation of moisture and the falling of drops of water on to the gas burners extinguishing the light, or impairing the efficiency of the burners.
hat I claim is- 1. In an apparatus of the class described, a water heating unit comprising abut-ting plates having inlet and outlet openings, and between which is a water passage of the form of a continuous spiral extending between said inlet and said outlet and consisting of a shallow channel whose walls are formed by the surfaces of the plates.
2. In an apparatus of the class described, a water heating unit comprising abutting plates having inlet and outlet openings, and between which is a water passage of the form of a continuous spiral extending between said inlet and said outlet, and consisting of a shallow groove formed wholly in g 1,012,6Lcu
the combination of an air-tight shell having an inlet for the water and an outlet for Water or steam, a series of heating units assembled in the shell in communication With the inlet and the outlet, and means to connect the units as a series to one another, a
series of gas burners for the respective unitssupported exterior to the shell and extending Within the same contiguous to the respective units. 1 In testimony that I claim the foregoing I have hereunto set my hand.
