ELECTRIC WATER HEATER.
Application filed December 8, 1926. Serial No. 153,259.
My invention relates to an electric water heating apparatus, and has for its object an y improved organization of parts by means of which water for domestic and similar purposes may be heated electrically at an appreciable distance, if so desired, from the point of storage or other supply of the water, and made available for drawing off as desired. In this construction the water tubes are made to function as the secondary circuit of a. transformer, while theI primary transformer is divided into a number of sections between which loops of thel water coil are interposed. I thus avoid the interferpass.-
IasGl,
Figure 2 is a. plan view, partly in sectionf taken along the line 2 2 of Figure 1 and looking in the direction of the arrows there shown.v l l A and B represent the frame sections of a support, between which are insulatedly located the several elements of the water heating construction. At Ck is shown a switch controlling the current from a suitable source of external power. D, E and F represent the high resistance wires connecting the switch with the binding posts G, H and I respectively, by means of which current is carried to the heating device. rkEach one of these binding posts forms the top of a resistance structure, in which respectively are spacedly positioned a pluralit of transformer primary elements 2, and G8, and H1, H2, and H3, and Ii, I2, and I3. Between these lie exposed portions of the several cores, as N, about which are Wound in horizontal series loops of the water-conducting pipes J, K, L, and M, the pipes J and K constituting the supply and return elements respectively of one series, while the pipes L and lM` function similarly as to the other series or water circuit, and all being connected with the tank 'or supplysource Z, positioned suitably above,
the electric heating device. `V`The supply and return portions of each pipe series J and K, and L and M, respectively are not appurtenant, as regards their coil portions, to any one of the vertically arranged resistance structures, but onthecontrary the intermediate portions of each, that is, the coils between the straight sections, as J and K, and L and M, respectively are formed into three series, horizontally aligned, each of which encircles a corresponding exposed port-ion of the core otreach of the resistance structures G, H and I; thus in Figure 2 the coil section R, S and T will be understood as appurtenant to anda part of the pipe circuit L and M, while if a similar section were taken through the corresponding` lower series of convolutions about the resistance Aelements G and H and I, they would form a similar connection kbetween the pipes J and K. Y
These series of tubes or pipes which I thus make to serve as secondary transformer elements may be used to effect the desired heating short-circuiting separately, each pair being connected by a plate or bridge of metal; in Figure 1 these are, for the sake of clearness, illustrated as at different heights, the plate P connecting the pipes J and K, while the plate Q functions similarly as to the pipes L and M. However, if desired one plate, as Q, might be connected with all four pipes, though in the preferred arrangement shown I am enabled to vary the degree of resultant heating by changes of one or both of the plates to a higher or lower position.
I thus make use of the tendency of the heated water to rise, and thus make way for the gravity-induced downward flow of the cold water through each of the inlet pipes Jand L. The coil sections, as R, S and T, not being positioned about the transformer primary in any case, and in fact spaced from them, and in case of their slight displacement actually insulated as well by their washers M, the heat of their water is com- Inunicated to the several transformer primaries.
Since to a degree the influence of the -water already `heated extends up into the inlet pipe of either series, thus tending to slacken the speed of the iiow through the coils and outletsections K and M of each series, it is sometimes advisable to eifect the Vinjection of a supplemental tlow of cold ill] water into either' or both of the coil series at a point relatively near Where the heating is going on most actively. 'llov accomplish this ll provide an auxiliary feed pipe V, which leads downwardly from the tank Q to connection with each of the pipe series, as at X and Y respectively. The inflow thus induced reaches the coil sections proper at the beginning of their point of actual heating, and thus may be used to accelerate the result desired, the possible How through the pipe V being controlled by a hand valve lV.
What li claim is:
l. An electric Water heating apparatus, having in combination with a plurality of spacedly positioned core elements, a plurality of spacedly arranged primary transformer elements appurtenant to each of said core elements, an energizing current Wire appurtenant to each of saidv cores and its 'group of primary transformer elements, a
wearer I adapted to serve as a secondary transformer element because of the contact of its coiled portions With said core elements, and a valve-controlled supplemental supply pipe connected with each of said Water coils adjacent that portion of each adjacent one of said core elements.
2. lin an electric Water heater, in combination with al plurality of Water coils having their cent-ral portions plurally looped, a plurality of core members spacedly arranged in parallel relation, a series of primary transformer members arranged in spaced relation about each of said core members, the central portion of each of said Water coils engaging about some portion of each one of said core members intermediate the location thereabout of said primary transformer members, electrical circuit Wires leading froman external source of power to each of said core melnbers, and an auxiliary Water supply pipe connected with each of said Wa-l ter coils adjacent their central core-engaging portions.
lin testimony whereof, l sign this specication.
