WATER-HEATER.

Specification of Letters Patent.

Patented J an. '2', 1919.

Application filed October 10, 1917. Serial No. 195,844.

To all whom it may concern:

Be it known'that I, VIRGIL F. DECKERT, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in ater- Heaters, of which the following is a specification.

My invention relates to water heaters and has for its object to provide a novel form of water heater adapted to be positioned in the circulatory system of ordinary heating apparatus for heating buildings such as hot water heating plants or steam heating plants. It is a principal object of my invention to provide such a device which shall contain a multiplicity of passages through which the water to be heated may be caused to flow, said passage-ways being themselves exposed to an extended flow of the heating medium such as steam or hot water. It is also an object of my invention in this connection to provide such a device which may be conveniently fabricated of cast metal in tw pieces and assembled with only one simple annular joint thus insuring tightness and simplicity of packing.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my inventionin one form, Figure 1 is a sectional elevational view of my invention. Fig. 2 is a transverse sectional view on line 2-2 of Fig. 1. Fig. 3 is a transverse sectional view on line 33 of Fig. 1, and'Fig. 4 is a section on line 4-'l of Fig. 1.

As illustrated my water heater comprises an inner casting member 10 and an outer shell 11. The shell 11 is a cylinder having a closed end 12. and an open end surrounded by a flange 13 which flange engages a corresponding flange 14: formed in conjunction with the end wall 15 of the central member 10. Apacking-ring 16 extends between flanges 13 and 14 and by meansof bolts 17 the parts are held together in water tight relation. Eye members 18 upon the top of the cylindrical portion of the shell 11 are adapted to serve as hangersby which the shell 11 and the inclosed core or interior member 10 are suspended in a horizontal position from the ceilingwor from brackets extending from the wall. Inlet and outlet pipes 19 and 20 respectively admit and discharge the heating medium of the circulatory system to the interior of the shell where it is constrained to effectively flow around the parts of the interior member 10 as will hereinafter be pointed out.

Formed in conjunction with the end plate 15 and the connected flange 1% of the interior member 10 is a cylindrical casing 21 having an end 22 and a transverse partition 23 as shown in Figs. 2 and 3. Opening through the end 22 into the chamber formed within the cylindrical member 21 are a multiplicity of pipes 25 f elongated or oval cross section as clearly indicated in Fig. 3. As shown, there are eight of these pipes, four of which communicate with the chamber 26 formed on one side of the partition 23 and the other four communicate with the chamber 27 formed on the other side of the partition 23. An inlet pipe 28 and an outlet pipe 29 per: mit the water to be heated to enter and leave the interior member. Spreader plates 30 and 31 are positioned immediately above the opening from pipes 28 and 29 insuring that the water in circulating n either side of the partition 23 shall go through all of the members 25. ends are united and open into a ring 33 shown in Figs, 1 and 4 which provides a circular channel 34 in communication with the interior of each of the pipe members 25. All

of the pipe members therefore are in communication at one end, through the channel 3% formed in ring 33 and at the other end the pipe members communicate with the base member 15, but only half of said members with each of chambers 26 and 27 formed in said base member. It will thus be seen that several tubes 25 (in the example shown there being eight'in number) are not only formed s s to provide a perfect circulatory arrangement with the fluid to be heated, going one way through half the tubes and the other way through the other half of the tubes, but the tubes are rigidly held at both ends in their separated and spaced relation. The ring 33 is provided with a multiplicity ofpassage-ways closed by screw plugs 35 by which access may be had to the interior of the several pipes 25 for cleaning or other purposes. These passage-ways have a still more important function forit is by this means that the core member formed within the various tubes may be removed after casting. This is an These members at their other important feature of my invention and one which is essential for its eilicient practlce, that the core member consisting of tubes 25 and the connecting and holding bases at tudinal grooves 37 and 38 which receive.

flanges 39 nd 40 On diametrically opposite pipes 25 which are connected at thelr center with a web 41, thus forming a partition which divides the space within shell 11 into two equal portions. The web 41 terminates some distance before reaching the end of the shell, as indicated at 4.2 in F 'ig. 1. The steam or hot water pipe 19 admits hot water or steam into the interior of shell 11 and said hot Water or steam is constrained by partition -41 to fiow from one end of the chamber within the shell to the other end thereof where it passes through and around the ends of tubes 25 and over the end 42 of the partition 41 and back through the other half of the chamber'to the return or outlet pipe 20. During all this flow'the heating medium is in intimate contact .with the extended walls of the oval shaped pipes 25 wherein water is circulating through inlet from pipe 28 and outlet through pipe '29. The efl'ect of this is to heat pratically instantaneously the water within the tubes 25 and to keep this water heated while the same is being withdrawn.

The advantages of my invention will be apparent. It can be, and has been in practice, made entirely of. two castings, the in ner core casting 10 and the outer shell castmay be employed in the laundry, and a third heater in the bath room. Thus no long runs of pipe are required for delivering the hot -water with the consequent loss of heat through radiation. There is no necessity of a great tank which over-heats the'kitchen or place of storage during the period when water'is not used and which, durin times of hot fire in the furnace may rum 1e and boil and cause discomfort and frequently injury through explosion of the heating coil in the furnace There is absolutely no loss of heat efficiency when hot Water is not being withdrawn. The heating medium will simply flow past the water containing core member, which being heated to the same temperature as theheatin'g medium has no effect upon it excepting only during the periods when hot water is being withdrawn.
