HEATER.

Application filed November 19, 1923. Serial No. 675,707.

To all whom t may concern.'

Be it known4 that I, DoNovni inwnY HUNT, a citizen of the United States, resid ing at Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful Improvements in Heaters, of which the following isa specification.

This invention relates to heating apparatus for use in residences or other places and has for its object the provision oi' a novel device embodying gas burners for heating a blast of air which is conducted to the rooms or other places to be heated.

An important and more speciic object is the provision of a device of this character having a peculiar circulation whereby none of the heat will be wasted but all utilized to act upon the coils through which the Vair passes so as to eii'ect rapid and positive heating.

An additional object is the provision ot' a device of this character which will be simple and inexpensive in manutacture, highly eiiicient in use, durable in service and a general improvement in the art.

Nith the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a vertical section through a device constructed in accordance with my invention,

Figure 2 is an enlarged detail view through one of the burners, and

Figure 3 is a detail section illustrating a modification.

Referring more particularly to the drawings I have shown the device as comprising an upstanding preferably cylindrical casing or shell 10 mounted upon legs or other supports 11. lVithin thetop of this shell or casing is a hemispherical distributor l2 from which lead pipes 13 which extend to the various rooms or parts ot the building to be heated.

Vithin the top oit the casing 10 is a partition 12L which extends from the distributor 12 .to the wall of the casing 10 to define a chamber 12c which communicates with the interior of the casing 10 through openings 121.V

Located within this casing and suitably supported therein is a coil 14 including outer and inner pipe members 15 and 16 respectively, the latter of which connects at its lower end with the outlet 17 of a blower 18 driven in any suitable manner. The upper end of this inner pipe 16 discharges into the bottom of the distributor 12 as shown at 16a. The air inlet to the blower comprises a coil 19 which has its intake end 2O at the upper portion or. the casing and which is arranged between the convolutions of the coil 14, the lower end of this coil 19 leading into the blower casing as shown at 21.4

Extending vertically along'one side or' the casing, exteriorly thereof, is a distributing gas Ypipe 22 connected with asuitable 'feed pipe 23. Extending into the casing are burners 24 which are connected with the pipe 22 and which are equipped with the usual mixer 25.v rPhe burners 24 are located within the coil 14 between the outer and inner pipes 15 and 16 thereof. Y

Located near the bottom of the casing are bowl shaped deflectors 26 at which terminate the lower ends of heat return pipes 27 which are curved outwardly away from the upper end of the coil 14 and which communi cate with the space between the coil pipes 15 and 16.

1n the operation it will be seen that the blower lwill suck in air throughthe coil 19 and will discharge air through the pipe 16 ot the coil 14. `illhen the burners 24 are in operation it is quite obvious that heat is applied to the space between the pipes 15 and 16 and this will certainly operate to heat the current or blast oit' air passing through the pipe 16 which air is discharged into the distributor 12 from whence it is conducted through the pipes 13 to the rooms or other places to be heated. The heat ascending through the coil 14 is not wasted but passes through from the upper end of the coil 14 into and downwardly along thepipes 27. The heat issuing fromr the lower ends ot these pipes is deflected upwardly by striking against the deliectors 26 and this heat then circulates through and about all the coils, assisting in Vheating them. All products of combustion escape through a flue pipe or chimney 28 which communicates with the top of the casing.

In Figures 1 and 2 the members 14, 15, 16 and 24 are all illustrated as being circular in shape. lt is apparent that it is not necessary that these elements have this particular configuration and for example I have shown, in Figure 3, corresponding elements 14k if M39-, ind 24?* which :ire arranged operate in the suine manner but rectangular in cross section.

Vl.Vhile .l have shown and described the preferred embodiment of my invention it is of course to be understood that l reserve the right to ineke such changes in the forni, construction and arrangement oil parts as will not departroin the spirit of the invention or the scope oi' the subjoined ciairns.

Having thus described my invention 7. claim:
