1 Claim.

same through the radiator and to provide air circulation means for forcing the air across the tubes of the radiator for heating the room.

A further object is to provide a device of this character adapted for enclosing in a suitable cabinet and providing a shield in the'cabinet between the blower and the burner to prevent interference of the burner by the blower and also to provide a stack for the burner within which the heating coil is positioned to increase the efiiciency of the heater and also having an elbow connected to the stack and extending from the cabinet for attaching to a suitable chimney flue.

A still further object is to provide an apparatus of this character of simple and practical construction, which is neat and attractive in appearance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a front elevational view,

Figure 2 is a vertical transverse sectional view,

Figure 3 is a vertical sectional view taken substantially on a line 3-3 of Figure 2,

Figure 4 is a horizontal sectional view taken substantially on a line 44 of Figure 3,

Figure 5 is a fragmentary rear elevational view,

Figure 6 is a sectional view through the stack showing the heating coil therein, and

Figure '7 is a similar view of a modified form of stack provided with a plurality of heating coils.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a cabinet preferably constructed of sheet metal and having an opening 6 in its front portion, a removable top 'I and legs 8 at each corner of the cabinet, supporting the walls of the cabinet in an elevated position above the floor. The bottom of the cabinet is open as shown to advantage in Figures 2 and 3 of the drawings, and the rear wall 9 is provided with a pair of hinged doors III.

Supported in the cabinet immediately behind the opening 6 is a radiator shell designated generally at I I, the radiator being of the automobile engine type and including the upper and lower tanks I2 and I3 connected by the usual vertical spaced tubes (not shown). The front and rear portions of the radiator may be covered with a screen or grille I4.

The upper tank I2 is provided with a hose connection I2 and the lower tank I3 is provided with a hose connection I5 with which hose I6 and I! are connected respectively thereto. The hose I6 and H are connected respectively to the upper and lower end of a vertically arranged heating coil I8 mounted in a pipe or stack I9; the stack being open at its upper and lower ends and has an elbow 20 attached to its upper end leading through the rear wall 9 of the cabinet for attaching to a chimney flue or the like (not shown). A damper 2 I, of the butterfly type, may be mount- I ed in the elbow.

A plurality of horizontal bars 22 are secured in the bottom portion of the cabinet on which is supported a pan 23 and a horizontal bar 24 extends above the pan on which is supported an oil burner 25 having a fuel tank 26 connected thereto by means of a feed pipe 21, the burner element 26 being positioned immediately below the open lower end of the stack I9. The stack is supported in position in the cabinet by means of a cross bar 28.

Immediately behind the radiator is a cross bar 29 on which is supported a fan motor 30 having the fan 3| attached thereto for blowing air through the radiator II.

The fan motor may be controlled by a conventional type of thermostat mounted at the desired position in the room.

Also supported on the cross bars 22 is a shield 32 positioned between the burner 25 and the fan to protect the burner from air circulated by the fan.

The radiator tank I2 is provided with a filler neck 33 and leading from the tank I2 is an overflow pipe 34 having its lower end terminating immediately above a drain bucket 35.

The legs 8 are provided with adjustable feet 36.

The coil I8 may be of a single type or may be in multiple units as shown at 31 in Figure 7, each coil being adapted for attaching to the upper and lower tanks of the radiator.

It is believed the details of constructions, advantages and manner of operation of the device will be readily understood from the foregoing= without further detailed explanation.

What I claim is:

In a room heater, a casing having an opening in the front thereof, a radiator mounted in the casing opposite the opening, a power driven blower mounted in the casing in the rear of the radiator to drive air through the radiator and the opening, a stack mounted vertically in the casing in the rear of the blower and including a damper controlled elbow portion at the upper end thereof and leading outwardly of the casing, a vertically disposed heating coil mounted in the stack to extend upwardly behind said blower, means connecting the upper and lower ends of said coil to the top and bottom of the radiator, a heating means in the casing directly under the lower end of the stack and coil, and a vertically arranged semi-cylindrical shaped shell mounted in the casing and receiving the lower portion of the stack and partly surrounding the heating means in front thereof to prevent the action of the blow- ELTON G. GIBSON.
