HOT-WATER- HEATER.

Specification of Letters Patent.

Patented Mar. 8, 1921.

it Application filed December 1,1919. Serial No. 341,831.

To all who-m it "mag comma:

Be it known that I, CHARLES HACKETT \Vrnwnrman, a subject of the King of Great Britain, and residing in the town of Kingsville, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Hot-'Water Heaters, of which the following is a specification This invention relates to improvements in hot water heaters, and the objects of the invention are to provide a heater which can be advantageously utilized in households or with heating systems generally, and in which the temperature of the circulating water may be kept at any desired height, so that the heater will require very little attention after it has once been set in operation.

Further objects are to provide an insulating means so that the heat will not be radiated from the heater into the cellar, but will pass upward through the heating system of the house in which the heater is installed, and generally to adapt the heater to better perform the functions required of it.

Vith the above and other objects in view, the invention consists essentially of the improved construction, particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings:

Figure 1 is a vertical section of the improved heater.

Fi g. 2 is a transverse section of the heater through one of the electrical resistances.

Like characters of reference refer tolike parts in the several figures.

Referring to the drawings, A. represents .a heater comprising a water chamber consisting of a central tubehaving a plurality of annular chambers 11 connected thereto and equidistantly spaced. These chambers 11 are incased in a casing 12 formed of double 'walls between which an asbestos or a nonheat conducting material 13 is packed to prevent radiation from the heater.

The casing 12 is formed in two halves so that it may be readily taken apart, and these are held in position by bands 14 embracing the outer periphery of the casing. Between the equidistantly spaced annular chambers 11 resistance coils 15 are located which are connected to a fuse block 16 spaced below the heater and this fuse block is provided with a plurality of plugs 17 connected to the resistances.

In the embodiment illustrated it will be seen that each resistance 15 consists of coils of wire insulated from each other. The number of resistance coils 15 will depend on the capacity of the heat.

The casing 18 is mounted on suitable supports 18. The upper and lower ends of the central tube of the heating chamber 10 are flanged as shown at 19 and 20 and heads 21 and 22 are attached to thosefianges by bolts or the like.

The head 20 may be connected by pipes 23 with the radiators of a building, and the return from the said radiators takes place through the pipe 2% connected to the head 22. The assembly of the heater will be readily understood from the foregoing de scription.

hen the heater is in use, the plugs 17 will be connected to a suitable source of power and water will be delivered to the chamber 10. As the coils of the resistance 15 become hot, the heat will be transmitted through the walls of the heating chamber 10, and heat the water therein, which will circulatethrough the head 21 and pipes 23 to the radiator and return through the pipes 24 and head 22 into the water chamber, so that a proper circulation of hot water will take place.

When it is neccessary to inspect the resistance 1.5, the bands 14; can be removed, and the casing 12 which is in two sections may then. be removed from the waterchamher and thus expose the resistance 15.

It will thus be seen that the construction of the heater is of an extremely simple nature and there is nothing liable to get out of repair during the period inwhich the heater is in use, while a periodic inspection of the heater and heating resistance can be made without inconvenience.

As many changes could be made in the above construction and many apparently widely diiierent embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim in my invention is:

A heater of: the class described comprising a water chamber consisting of a central tube having a plurality of annular chainhers equidistantly spaced from each other, electrical heating resistances between adjacent annular chambers, a sectional casing surrounding the water chamber provided with hollow walls, a filling of non-conducting material in the hollow walls, bands holding the sections of the casing together, heads on the outer and lower ends of the central tube, 10 and a plu 'ality of fuse plugs located below the heater, and connected to the resistances. In witness whereof I have hereunto set my hand in the presence of two witnesses.
