STEAM WATER HEATER.

Application led November 13, 1922. Serial No. 600,504.

To aZZ whom t may conce/m Be it known that I, CUTHBERT LAVINGTON DIXON, a subject of the King of Great Britain, and residing at the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented anew and useful Steam Water Heater, of which the following is the specification.

The invention relates to heating devices as described in the present specification and shown in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features pointed out broadly and speciiically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects ofthe invention are to econ omize in the consumption of fuel by directing the flow of water so that there is an effective distribution of the heat around and about the stream; to maintain a quantity of otherwise in which it may be used; to furnish satisfactory hot water heating systems in houses, commercial and public buildings and plants; to facilitate assembling of the parts in such devices and repairing and replacing of parts; to reduce the oost of maintenance in heating plants; and generally to provide in such devices a heating surface great in respect to the size of the plant and at the same time cheap to provide, efficient in use and of a durable nature.

In the drawings, Figure 1 is a longitudinal sectional view of a casing showing the tubes and header in section.

Figure 2 is al cross sectional View on the line 2 2 in Figure 1.

Figure 3 is a cross sectional view on the line in Figure l.

Figure 4 is a cross sectional view on the line 4-4 in Figure 1.

Like numerals of reference indicate corresponding partsv in the various figures.

Referring to the drawings the header indicated by the numeral 1 is formed with an outer end wall 2, a longitudinal outer wall 3, an inner end wall4 and an intermediate wall 5 and through the outer end wall 2 the water inlet 6 at the lower end and the water outlet 7 at the upper end lead to the inlet chamber 8 and from the outlet chamber 9.

The intermediate outer chambers 10 and titions 18 and 19 and from the outlet chamber 9 by the 'partition 20, the partitions 18, 19 and 20 extending' from the intermediate wall 5 to the inner wall 4.

Threaded orifices 21 are made through vthe inner wall 4 for the outer tubes and threaded orifices 22 are made through the intermediate wall 5 for the inner tubes.

The inner tubes in rows 23, 24, 25, 26, 27, 28 and 29 are open at both ends and screwed into the tube orifices 22 and are therefore in communication with the chambers 8, 9, 10V

and 11, there beingy two rows of tubesto each chamber except the outlet chamber 9, which has only the one row 29 emptying thereinto.

rlhe outer tubes in rows 30, 31,32, 33, 34, i

35 and 36 are closed at one end 37 either capped or welded and at their open ends they are screwed into the tube. orifices 21 and contain the major portion of the said inner tubes, the latter being of much smaller diameter and' terminating at one end short of the length of said outer tubes and at their other end projecting from the mouths of the outer tubes to the intermediate wall 5.

The shell 38 encloses both the inner and outer tubes and is rigidly secured to the header 1 and also contains the storage tank 39 which is of segmental shape in cross section and is rigidly secured by the flanges 40 and 41 and spaced from the shell and located immediately above the tubes, having the opening 42 leading to and from the outlet chamber 9, in order that the water may be free to flow in and out.

The steam inlet 43 leads intov the shell 38 and is connected in operation to a suitable steam plant and the steam outlet- 44 leads from the shell. The steam inlet and outlet are shown as through the upper side of the shell, but they may be placed, where the most efliciency is assured.

The condensation drain 45 is through the bottom of the shell 38.

ln the operation of this heating device the Water inlet is connected to a suitable Water supply and the outlet to the heating system or such other arrangements according to the conditions of use. rlhe Water entering at the inlet flows into chamber 8 and through the inner tubes 23 and 24 from said chamber to the ends of the corresponding outer tubes 30 and 31 returns along the said outer tubes 30 and 3l.

Emptying from the tubes 8O and 3l into the chamber l5, it flows into the tubes 32 and along said tubes to the closed ends and back by the tubes 25 to the chamber l0. F rom the chamber .l0 the Water flows through the tubes 26 to the end ot the tubes 33 and back through the latter to the chamber 16. The Water then flows along the tubes 3a and back throug'h the tubes 27 into the chamber l1 from Which it flows through the tubes 28 and back by the tubes 35 to the chamber 17 and thence along the tubes 36 and back through the tubes 29 to the outlet chamber S) Where it flows to the various parts of the circulating system alter filling the storage tank 39. The steam is distributed throughout the interior of the shell 38 flowing over and about the storage tank and around all the outer tubes. This may be reversed it desired and have the Water in the shell and the steam in the tubes.

It may be here mentioned that tubes 29 shown in one row are preferably twice the diameter of the other inner tubes in order to permit the flow of lan increased volume ot Water, though it may be arranged by having more tubes.

What I claim is:

l. A steam Water heater, comprising a header having inner and outer Water chambers, the lovver outer chamber forming an inlet compartment and the upper outer chamber torming an outlet compartment, inner and outer pipes communicating With said outer and inner chambers respectively to term a passage between said inlet and outlet Y compartments, a cylinder enclosing said pipes and a longitudinal hot Water chamber above said pipes and spaced from the cylinder Wall at the top and secured to the end wall thereotl and to said head and communieating With the outlet chamber in said head.

2, lnheating devices, a header having inner and outer end Walls, an intermediate Wall and partitions forming inlet, outlet and intermediate chambers, a storage tank communicating With said outlet chamber, a shell enclosing said storage tank and secured to said header and tubes connected to the. inner and intermediate. Walls and providing communication` between the inlet, intermediate and outlet chambers.

Signed at Montreal, Canada, this 30th day of October, 1922.
