ELECTRICAL HEATING DEVICE.
Application filed March 2, 1926. Serial No. 91,793.
The invention relates to electrical heating apparatus, and has for an object to provide a novel construction in means for applying and COIISGIVlIlg heat generated electrically.
It is a particular purpose to evolve means for efficiently heatlng stoves, furnaces, and for heating and vaporizing liquids- Specially, in the present embodiment of the invention, it is adapted to the vaporization of water, in such manner as to supply steam to a heating system, and it may be used as an auxiliary to an ordinary coal burning boiler and circulation system, or as the sole vaporizing unit for such a system.
It is a specific purpose in the present showing to evolve a readily constructed and easily assembled vaporizer or heater unit, adapted to be produced at low cost, and which may be easily installed, and maintained. It is an object toprovide novel features in the parts, adapted to increase the efficiency of the apparatus and facilitate assembly and repair.
It is an object to present a novel heat diffusing unit in such devices.
It is also a purpose to coordinate a heater unit of this kind with a boiler and heating system in a novel manner.
Additional objects, advantages and features of invention reside in the construction arrangement and combination of parts as will be understood from the following description and accompanying drawings,where- 1n-- Fig. 1 is a longitudinal sectional view of one embodiment of the invention,
Fig. 2 is a view of the left end of the diffuser unit removed,
Fig. 3 is a view of the water chamber from the open end,
Fig. 4; is a diagrammatic showing of the use of this device as an auxiliary in a steam heating system or hot water heating system.
Fig. 5 is a detail elevation of a coil assembly adapted to the uses indicated.
There is illustrated a cylindrical chamber body 10, adapted to be cast in metal, one end being closed by an integral head 11, while a removable head 12 is bolted snugly upon the opposite end, the wall 13 opening flush at the end and being suitably thickened to receive this plate and the bolts by which it is secured. This chamber is jacketed by an enclosure 14 of suitable material after approved methods for conserving heat within of the diffuser at its inner end. At the op the chamber 10. In the present instance the jacket is spaced from the chamber body so as to form a dead air space, and if desired a pipe 15 may be led off from the top of the jacketing to convey hot air therefrom for utilization as desired. The chamber 10 is fitted with a water gauge 16 of ordinary construction; a safety valve 17 is incorporated when the device is used independently of a steam boiler; mercury and pressure gages 18 and 19 are also installed, while a water supply connection and a drain cock are shown at the bottom of the chamber.
At the top of the chamber a steam outlet pipe 20 is shown, adapted to serve as the riser in a piping system for heating, and at the bottom a pipe 21 leads into the'chamber, to be used as the return of such a system.
The head 12 is centrally thickened and formed with an axial opening through which there is projected from within the chamber the tubular neck 24 of a bellowslike heat diffuser 25, preferably formed ofa metal or other material of high heat trans mission efliciency, nickel-chromium steel alloy being one that may be used, it being desirable that the material be also sufiiciently refractory to resist heat properly for the purposes contemplated. This diffuser is formed with a multiplicity of hollow disklike members 26 connected by reduced necks 27 formed integrally therewith, or otherwise, so as to form one hermetically sealed chamber throughout the series of members 26. The outer walls of the end members 26 are thickened to enable the ready support of the diffuser within the chamber 10 by coengageme-nt between the body of the chamber and these walls. On the head 11 of the chamber 10 there is formed a ledge 28 having an upper side adjacent the longitudinal axis of the chamber 10, while the adjacent wall of the difiuser is formed with a lug 29 adapted to rest'upon the ledge for support posite end the diffuser is secured by bolts 30 engaged through the head 12 and these serve also to secure centrally the adjacent end element of the jacket 14, a ring 31 being clamped thereagainst by the bolts.
The neck portions 27 have an interior diameter corresponding to that of the neck 24, whereby an electrical coil assembly may be introduced slidably from one end through the diffuser, as will be described. The inner 36 is led withsuitable bushing to the aldjacent end of the heater coil 33, while from the inner end of the coil 33 a wire 37 is led inward through the porcelain and through the tube 32 outward and through the outer end of the tube, as shown.
When the appliance is to be used as the sole heating element for a system, it may be mounted in any convenient location suitable for the purpose. 'When used as an auxiliary to a steam boiler, advantage may be taken of cooperation between my appliance and the regularboiler in maintaining the-water supply safely and efficiently within the proper limits: That is to say, the chamber 10 and assembled parts is preferably mounted at such height with respect to the regular boiler 40, that the normal water level in such boiler, as indicated by the dotted line in Fig. 4, will be closely adjacent the upper edges of the elements 26 of the difluser 25. The boiler 40 will serve as an automatic replenishing means for the appliance as water is vaporized, avoiding liability of excessive exhaustion ofthe water content. In case my apparatus is used as an independent heating source a reservoir corresponding to the boiler 40 in horizontal dimension may be employed after themanner'illustrated but the lower part of such reservoir need not of "arrangement indicated;
course extend as low as the boiler shown, and may be of less depth than the chamber 10 the large horizontal extentas compared to the chamber 10 being the principal element tobe embodied along with the relative In Figure 5, there is illustrated a modification of the mounting of the heater coil, adapted specially for use as an insertable element in difl'users such as here, shown, or'
in fireboxes of stoves and furnaces and heaters of various kinds. In' this instance, a cylindrical porcelain core 50 has mounted thereon a multiplicity of thin sheet metal discs 51of. ametal adapted to be heated readily to incandescence, these discs are andv the cap plate. Through the plate 34 a wire stamped from sheet metal with laterally turned outer edges 52 in a groove shape, adapted to permit the laying of a heater coil thereon for retention of one convolution on each disc. The central portion of the disc is also extruded laterally to form a hub flange 53 fitting snugly the porcelain core. The discs are spaced apart by small porcelain rings. The outer parts of the discs are coated with porcelain enamel or the like, or other insulation resistant to the heat which may be expected. This mounting provides for an intimate circulation of air or other fluid'or liquid within and around the heater coil so that a maximum of heating efficiency is gained when it is energized.
' The core may be constructed in various ways for mounting in the various situations where required for use.
I claim:
1. In a-device'of the character described, a liquid containing chamber, closed at one end and having an interior rest at its inner end,
a removable head secured on the opposite end, and a hollow diffuser secured to the removable head longitudinally slidable in the chamber and removable with the head, said diffuser having-a lug at its extremity adapted to engage said rest for support.
2. A heater unit comprising a core of nonconducting material, a multiplicity of thin sheet-metal discs in mutually insulated spaced relation mounted thereon, and a heater coil having respective convolutions each in the form of a helix having anan'nular axis and peripherally carried by a respective disc aforesaid in intimate heating relation thereto.
3. A heater unit comprising a core of nonconducting material, a multiplicity of thin sheet metal discs in mutually insulated spaced relation mounted thereon, and a heater coil having respective convolutions mounted in intimate relation torespective discs, each disc being formed with a peripheral coil-retaining groove.
, 4. The structure of claim 3 in which each disc is formed with-laterally turned edge portions shaped to form a peripheral groove.
5. The structure of claim 3 in which the discs are slidable on the core and small insulating washers interposed between the discs.
