This invention relates to hot air heaters and particularly to devices of this character which may be installed in a cabinet formed of insulating material and has for its object the production of a heater in which the air admitted thereto may be heated to high degree of temperature with a minimum expenditure of oil in the oil burner utilized therewith. v

This object is attained by the mechanism illustrated in the accompanying drawings.

For the purpose of illustrating t-he invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limit- 2U ed to the precise arrangement and organization of these instrumentalities as herein shown/and described except as required by the scope of the appended claims. Of the drawings: D Figure 1 represents a vertical section of a hot air heater embodying theprinciples of the present invention, the cutting plane being on line 1, 1, on Fig. 2. f

Figure 2 represents a horizontal section of same on

3, 3, on Fig. 1.

Figure 4-represents a vertical transverse section on line 4, 4, on Fig. 1, and Figure 5 represents a sectional detail showing how the hot air pipes are mounted in the partitions and the unions are connected thereto.

Similar characters indicate like parts throughout the several figures of the drawino's.

' 2Tn thedrawings, 10 is a cabinet, the side and top walls of which areformed of insulating material adapted to prevent the escape of heat therefrom.

TWithin the cabinet and parallel Vwithv the end walls thereof are metal partitions 11 extending from the bottom of the cabinet to the top wall thereof.

These partitions 11 are spaced from the end walls of the cabinet and form' compartments 12 entirely closed.

These compartments are filled with dead air which has no circulation.

Between the partitions 11 are a plurality of pipes 18, the ends of which extend through the partitions 11 and are connected in series by unions 14 within the compartments 12.

By means of these unions a continuous conduit is formed, the lower end of which communicates with a pipe 13 through which cold air is admitted to said conduit.

The upper end of the conduit has an elbow 16 connected thereto within a compartment 12 and from this elbow extends a pipe 17 through which the heated air passes upwardly to the registers in the various rooms of the house or apartment in which the cabinet is installed.

In the lower end of the cabinet 10 and beneath the pipes 13 are'oil burners 18, one or both of which may be used to heat the air passing through the

conduit

13, 14.

Access to the burners is obtained through the door 19 in the front wall of the cabinet 7 10 and on either side of the door 19 are open- 1ngs20 for the admission of air to the burn- GTS.

wall of the cabinet thereby forming a pas- 9 sage 23 communicating near its lower end with an exit pipe 24 leading to the chimney Hue.

This exit pipe 24 has a branch pipe 25 ex'- tending therefrom and communicating with the passage 23 near the top of the partition 22.

This branch pipe 25 is provided with a valve or damper 26 which may be closed when the heater is in operation and it is desired to have the products of combustion enter the pipe 24 at its lowest end.

The bafiie plate 21 is curved in such a manner that the products of combustion from the oil burner 18 will be deflected upwardly into contact with the various pipes 13 to be discharged at 27 into the upper end of the passage 23.

Each partition 11 is provided with an annular flange 28 surrounding the end of each pipe 13, and each pipe is provided near each end thereof with a stud 29 adapted to contact with the inner faces of the partitions 11 to prevent any end movement of said pipes relatively to said partitions 11.

All of the products of combustion from the oil burners 18 are confined within the chamber`frmed by the front wall ot the cabinet, the end partitions 11, and the back partition 22,180 that all of the pipes 13 disposed between the partitions 11 are subjected to these products of combustion.

AS a consequence the cold air first admitted to the lower pipes will be heated to some extent and as this air partially heated moves upwardly through the

conduit

13, 14, it will be subjected to more and more heat until it passes from the upper pipe 13 into the vertical pipe 17.

" At this time it will be intensely heated.

The products of combustion from the burner 18 will also heat the end partitions 11 and back partition 22, and this heat will radiate from these partitions into Contact with the pipes 13, thereby greatly assisting in the heating of the air passing through said pipes.

' By means of the construction herein shown which may be constructed at little cost, a great quantity of hot air may be provided Sufficient to heat Several rooms with a minimum expenditure of oil in the oil burners.

Itisbelieved that the operation and many advantages 0f the invention will be understood without further description.
