Application November 30, 1951, Serial No. 259,087

1 Claim. 1

My invention relates to improvements in combination space heaters or coolers for general household or office use.

The primary object of my invention is to provide a simply constructed, inexpensive device adapted for use either as a space heater or cooler and for convenient moving about from room to room.

Another object is to provide a device for the above purposes which is easy to service, can be operated at a low cost, and is not liable to get out of order.

Other and subordinate objects, within the purview of my invention, together with the precise nature of my improvements will be readily understood when the succeeding description and claim are read with reference to the drawing accompanying and forming part of this specification.

In said drawing:

Figure 1 is a view in plan of'my invention in the preferred embodiment thereof shown partly in section;

Figure 2 is a view in front elevation partly in section, and

Figure 3 is a view in side elevation partly in section.

Referring to the drawing by numerals, my invention, as illustrated, comprises a rectangular flat base I of any suitable material supporting at opposite sides thereof in parallel spaced apart relation a front heat exchanging radiator 2 and a rear water storage tank 3.

The radiator 2 comprises an upright rectangular, hollow frame, of hollow square form, including a horizontal top and bottom 4, 5 respectively, vertical sides 6, and a plurality of vertical water pipes I connecting the top and bottom 4, 5 between the sides 6 and suitably fixed at the ends thereof in said top and bottom 4, 5 in laterally spaced relation to establish communication between said top and bottom 4, 5 and provide an air space between adjacent pipes. An electric heating unit 8 of conventional form extends into the bottom 5 of the radiator 2 from one side 6 thereof and is adapted for connection by a lead cable 8 to the electric light circuit of a house or oflice building.

The water storage tank is also rectangular and is substantially the same size as the radiator 2, but of larger capacity, with a topfiller neck 9 closed by a cap II). A water return pipe II extends horizontally from the top 4 of the radiator 2 into the top of said tank 3 at corresponding sides of said radiator 2 and tank.

A fan I2 is mounted behind the radiator 2, in the space between said radiator and the tank 3 on a horizontal shaft I3 aligned with the horizontal center of the radiator 2 and journalled in a pair of uprights bearing brackets I4, I5, bolted, as at I6, to the base I.

A suitable electric motor I! on the base I vertically aligned with the shaft I3 is operatively connected to said shaft by a belt and pulley connection I8.

A suitable water circulating pump I9 is bolted on the base I, as at 20, between the radiator 2 and the tank 3 and at the opposite side of the base I from the water return pipe I i, and has its intake side connected to the bottom of the tank 3 by a pipe 2| and its output side connected to the bottom 5 of the radiator 2 by a pipe 22, said pipes 2I, 22 being connected to the tank 3 and radiator 2 at the sides thereof opposite the return pipe I I. The pipe 22 is connected to the radiator bottom 5 directly opposite the heating unit 8. The motor I! is adapted to be connected by a lead cable 23 to the light circuit before mentioned. The shaft 3I is operatively connected to the pump I9 by a belt and pulley connection 24.

In using the described invention as a space heater, the storage tank 3 is filled with Water which is drawn from the bottom of said tank 3 by the pump I9, through the pipe 2I and forced into the bottom of the radiator 2 at one side thereof to find its way through the bottom 5, sides 6, top '4 and water pipes I to the return pipe II and back into the top of the tank 3. The water is heated by the heating unit 8 and the fan I2 blows atmospheric air through the radiator frame and between the water pipes I which is thereby heated to be blown forwardly into a room or the like. When the invention is used as a cooler, the tank 3 is filled with ice and water and the heating unit 8 rendered idle, the ice water being circulated in the same manner as described with reference to heating but the cooled atmospheric air being blown through the frame of the radiator 2 and between the pipes I by the fan I2.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention, Without further explanation.

Manifestly, the invention, as described is susceptible of modification, without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

Having described my invention, what is claimed as new is:

In combination, a base, a heat exchange radiator rising from said base at one side thereof and having a top, bottom and sides, a water tank rising from said base at the opposite side thereof and spaced laterally from said radiator, a fan between said radiator and said tank mounted on said base for blowing air outwardly through said radiator, a pump on said base between said radiator and tank, a motor on said base operatively connected to said fan and pump, a heater in the bottom of the radiator at one side thereof, a water intake pipe extending from the bottom of the tank to the intake side of the pump, a water discharge pipe extending from the discharge side of the pump to the bottom of the radiator and same side as said heater and discharging directly opposite the heater, and a water return pipe extending from the top and opposite side of the radiator to the top of the tank.
