UNITED. STATESl CHARLES DARGENT, OF BROOKLYN, YORK. i
y WATER HEATER.
Application filed November 19, 1924. Serial No. 750,872.
To all whom t may concern: f Y
Be it known that I, CHARLEs DARGENT, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of. New York, have invented a new and Improved Water Heater, `of which the following is a full, clear, and exact description.
lThis invention relates to water heaters or generators to be used in connection with heating steam and hot water boilers and has for an'object to provide an improved construction which may bek readily applied to a boiler and which is of simple construction. Y f
Another object of the invention is to provide an improved generator or water heater whereinthe heating coil is positioned with its ends embedded in a surrounding casing so as to eliminate leaking by expansion and contraction.
In the accompanying drawing- Figure 1 is a longitudinal vertical sectional view through a heating boilerrwith an embodiment of the invention applied thereto, said embodiment being associated Y with a domestic boiler.
Figure 2 is a longitudinal vertical sectional view through a generator embodying the invention, the same being on an enlarged scale.
Heretofore, various forms of water heaters have been provided for heating boilers used in ordinary dwellings and other places. These water heaters usuallyV consist of some form of circulating pipes or fittings projecting into the lire box so that water passed therethrough will become heated without materially affecting the action'of the boiler. In the present invention, an improved structure of this general type has been provided which is arranged exteriorly ofthe boiler but which absorbs the heat units from. the boiler for heating a supply of'water.
In the accompanying drawing, 1 indicates l a heating boiler of any desired kind, said boiler being shown as provided with a water chamber 2. This construction is old and well known andforms no part of the present invention. Associated with the boiler 1 is a water heater 8 disclosing an embodiment of the invention, said heater being connected with a domestic boiler 4 whereby the heated water may be stored for use at any time. Suitable connecting pipes or nipples 5 and 6 are threaded into the casing of the stove 1 so that these pipesy will be in free communication with the water chamber 2. The pipes or nipples 5 and 6 are also threaded into bosses 7 and 8 projecting from the casing 9' of the heater 3 whereby water from the water chamber 2 may freely circulate through the casing 9. f This readily takes place as the pipe 6 is an appreciable distance below the pipe 5 whereby the hot water may enter the casing 9 through pipe 5 and pass out through pipe 6. Arranged in the casing 9 is a. heating coil 10 formed of copper or brass and connected with this heating coil are pipes 11 and 12 used to connect the coil to the top and bottom respectively of the boiler 4 from which water may be drawn off from time to time as desired. It will be i understood that suitable pipes extend from the upper partof boiler 4 to any desired place where the water is to be used and also the lower part of the boiler is connected with a source of water supply, as for instance, the ordinary water main of the city.
In order to eliminate packing and also to prevent leaking at the oints where the pipes 11 and 12 are connected, a special structure is 'provided in respect to the casingr9 and the coil' 10. The coil 10 at each end is provided with an outwardly extending portionv 13 and an upstanding flange 14. The ends of the coil 10 are formed in this manner and a coil is placed in thecore before the casing. 9 is east, which .casing is preferably of cast liron or steel. During the casting operation, a quant-ity of the iron or steel is caused to form the boss 15 and also the underlapping flange or section 16 whereby the portions 13 and 14 are iirinlyembedded in the cast iron. It will thus be seen that the copper or brass coil 10 has its ends embedded in the ends of the casing 9 and, consequently, there can be noA leakage between the respective parts. The openings in the bosses 15 l.are threaded and the threading is carried downyan appreciable distance into the coil 10 so that when the respective pipes 11 and 12 are screwed in place they will first pass through the threads on the cast iron and then inter-y lock with the threads on the coil 10. As the material of coil 10 is much softer than' thek iron or steel, there will be somewhatv of a yielding action which will distortv these threads as soon as the respective pipes 11 and 12 have been screwed down tight. This distortion of the soft threads of the coil 10V will produce a water-tight connection without the use of packing and maintain the tight connection as the parts Vary in teniperat-nre.
lhat I elaini is 1. A water heater, comprising a metallic casing formed with hollow internally threaded bosses at each end, a lead-in-pipe near one end of the easing, a lead-out-pipe near the opposite end of the casing, a heating coil mounted in the easing and formed with integral Flared ends, said easing being east around said flared ends whereby said ends are embedded in the casing, said flared ends being internally threaded and arranged in line with the threaded portions of the bosses *for receiving connecting pipes Whereby part oi" the threads of the connecting pipes will engage the threads of the bossesl and part will engage the threads in the ends of the coil.
2. A Water heater, comprising a eastmetal easing formed with a hollon7 internally threaded boss at each end, said bosses being adapted to have pipes screwed therein, and a second pair 01"' hollow internally threaded bosses presenting inlet and outlet openings lfor the easing, a heating eoil positioned in the easing having integral ared ends embedded in the end bosses, said end bosses being east around said flared ends.
3. A water heater, Comprising a ared end Coil7 and a easing surrounding sai'd coil, the `liared ends oitl said coil being embedded in the end Walls of said easing and terminating between the surfaces of said walls, said Walls haring openings therein eo1nmunieating with said coil.
4. A Water heater, comprising a coil open at both ends, and a easing surrounding said coil, the ends of said coil being embedded in the end Walls ot said easing and terminating between the surfaces of said Walls, said Walls having openings therein Communicating with said coil.
