Referring to the accompanying drawings by numerals! indicates a block which is a metal casting and maybe cast of different kinds of metal, as for instance, aluminum, iron, and the like. This block is arranged in a casing 2 which is identical with'that disclosed in my pending application above referred to. Arranged below the block i is a base 3, also identical with that shown in my prior pending application. The base 3 is provided with superheating chambers l having outlets 5. A tubular threaded member 6 pro-- vides communication between the passageway ,1 and a transverse superheating chamber 4' which distributes steam to the various chambers 4. The

I through the coil pipe 12," and I thence through ajtubular' fittingii into the inlet 'porti fl'ias shownjin Fig1f4. "As thecoil pipe 22 r is near the remainingparitfof the 'i'ro'nQWater .passi'ns'through this coilwillhecome'heated and 'rnay ev'en'nbe' converted into 'a low?qualityor grade of steam. Conseqjiently, hot water'or low grade steamis "dischargedinto'th'e inlet port 24.

- The inlet port 24 merges into a tubular passagethe block could be cast around tubes-or certain portions of the passageways could be drilled way 25 which extends around the edge of the side across the front; near the other side across the backand merges into a right-angled portion which, in turn, merges into an outlet port 21, I

as shown in Fig. 7. ,The passageway 25, as well as the , ports 24 and 21, are preferably formed by coring when the block I is cast, but if desired and the outer parts closed with plugs. Preferably, however, the passageways are cast and usually after the sand is removed the passageways are more or less rough. This provides an increased surface contacting with the steam for more'quickly heating the same. The steam from the passageway 25 is discharged through the port 21 into the first steam-heating chamber '28 where it is further heated and then passes through the construction Just described in'regardto base I, valve 'struc'turesl 0 into the second steam-heating steam in the superheating chamber 29 may quickly flow into the superheating chambers 4 and 4' and then be discharged through the outlet jets or passages 5.

It will be observed that the block I is cast in one piece and that all the chambers or passageways therein are formed in this casting so that as the electric heater 8 functions block I will be heated and, in turn, will provide the desired heat for the steam as it passes from one chamber to the other.- It will be noted that the steam accumulates in passageway? and the heating chamber 28 and is allowed in chamber 29 only intermittently unless valve I0 is held open. a

In Fig. '1 a slightly modified formor block I is" disclosed. This block is identical with block l'except for the passage which is provided with a slight offset 31 in the rear, passageway 32,and insteadvof the passageway 26 there is provided 'a second rear passageway 33, which merges into a side passageway 34 and a transverse passageway v 35. The outlet end of passageway 35 has anoutlet port similar to port 21 shown in Fig. 5 and thereby discharges into the chamber 28. This provides a greater or rather longer path for the flow of steam and, consequently, permits the'steamto absorb more of thehea't units before the stream is discharged into the heating chamber I claim: t i
