Description
This invention relates to water heating units for boilers, furnaces and the like; and theobject of the invention is to provide a unit of this class comprising a casing composedof two substantially dish-shaped parts bolted or otherwise secured together to form a water circulating chamber therethrough, and further to the arrangement of an electric heating coil in the circulating chamber of said casing, the coil being in the form of 10 .a double spiral or formed from .a continuous coiled body with the ends of the coils extending outwardly through opposed sides ofsaid casing; a further object being to provide motor driven means for supplying electric energy to the heating coil of the unit so as to supply the proper voltage and amperage to the heating coil to render the same efficient in the heating of water or other fluid circulated therethrough; and with these and other objects in view, the invention consists 39 in a heater oi the class and for the purpose specie fied, which is simple in construction, efiicient in use, and which is constructed as hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:
4 Fig. 1 is a diagrammatic view illustrating one use of the water heater.
Fig. 2 is a transverse section of the heater shown in Fig. 1 with the heater coil shown in section and in elevation, the section being on the line 2-2 of Fig. 3.
Fig. 3 is a sectional view through the center of the casing showing the heater coil in elevation.
Fig. 4 is an enlarged detail view of the tubing from which the heater coil is formed; and, to Fig. 5 is a view similar to Fig. 2 showing a modification.
For the purpose of illustrating one .method of carrying my invention into eilect, I have indicated in Fig. l of the drawing at 5 a part of a fur- 45 nace, range or boiler, with which a pipe '6 is coupled to communicate with the lower portion of the water leg or jacket of the boiler; and 1 is a pipe communicating with the upper portionoi the water jacket.
50 At one side of the furnace or range 5 is a heater casing 8 consisting of two substantially dish- shaped parts 9 and 10, adjacent surfaces of which have outwardly extending flanges H and I2 respectively which are bolted or otherwise 55 secured together as indicated at l3 to form a circulating chamber l4 within and between the parts 9 and I0. Both parts 9 and I0 have beveled walls 911, 13a, adjacent the flanges which produce of the entire casing a substantially disc formation. 5
On the beveled surfaces 9a, a of each part 9 and H! are outwardly projecting bosses 9b, lflb, with which the pipes 1 and 6 respectively are coupled so that water from the boiler may be circulated from the pipe 6 upwardly through the 10 chamber I4 and out through the pipe 1 into the top of the boiler. Arranged within the chamber M is an electric heating coil l5 which may be constructed of any desired or suitable material, but which in the construction shown and as 15 viewed in Fig. 4 of the drawing consists of an outer tube iii of copper or similar material in which is an insulating tube or sheath l1 within which is a resistance wire or wire coil Ill. The tube I6 forming the heater unit I5 is spiralled at each side l5a, |5b in the manner indicated in Fig. 3 of the drawing so that one end at l9 of the heater tube l6 may pass through one side wall of the casing part 9 to the center or axis of the spiral Mia and extend outwardly in spiral fashion and then across by the member I50 to the spiral I5b and the end 20 thereof will extend outwardly through the side wall of the other casing part H]. In this connection, it will be seen upon a consideration of Fig. 5 of the drawing that the structure of the heater coil I5 can be slightly modified by simply spreading the separate coils to spread the unit over a greater area of the chamber M, and aside from this change, the structure of the device shown in Fig. 5 is similar to that shown in the other figures, and therefore, like references will indicate like parts.
Coupled with the resistance wire l8 of the heater unit where it extends through the ends I9 and 29 by any suitable source or" electrical connectors, are wires 2| and 22 respectively which are coupled with a generator 23 driven by a suitable motor 24. The motor 24 in the construction shown is an electric motor in circuit with a source of electric supply controlled by a switch 25 but preferably having a thermostatic controlling element 25 therein for maintaining desired temperature of the water in the upper portion of the boiler.
It will be understood at this time, however, that the use of the element 28 is not absolutely essential, and furthermore, the illustration of use of my invention diagrammatically in Fig. l of the drawing is simply suggestive of one method of carrying the invention into eifect, and other adaptations and uses of the heater may be made. In other words, the heater may be used as a heater for fluids, and in the use in connection with boilers, ranges and the like, the primary purpose of the heater is to function in the manner of what might be termed a superheater to more quickly raise the water in the top of the boiler to a desired temperature in a hot water heating or supply system or in a steam supply system.
My improved heater will be used primarily when it is required to quickly increase the temperature in the boiler and may be further utilized to maintain the desired temperature in the event of any sudden drop therein. It will therefore appear that the heater will have in most cases an intermittent use except in cases where a constant drain is made upon the heating unit or system employed, in which cases, my improved heater may operate constantly for an indefinite period of time. By employing the current supply herein described, it will be understood that the desired or required electric energy may be supplied to the heater at a relatively nominal cost, thus eliminating excessive drain on the current supply consumed in the operaton of the heater.
