Claim 3
Dependent Claim
63 words
The apparatus of claim 1 wherein said fan is reversible and said front wall vent is positioned at the bottom of said front wall whereby air heated bY said radiator may be forced out of the top wall vent when the fan is rotating in one direction and out of the front wall vent when the fan is rotating in the opposite direction.
Claim 4
Dependent Claim
122 words
The apparatus of claim 2, together with means connecting said radiator to said reservoir for conducting the overflow of radiator fluid into said reservoir, means for deenergizing said fan and said heater when the fluid in the reservoir falls below a predetermined level, said deenergizing means including a float in said reservoir, a rod connected to said float, and a switch mounted on said housing, one end of said rod passing through aligned apertures in the housing and reservoir to said switch and actuating said switch when the fluid level in the reservoir falls below a predetermined level, and a warning lamp connected to said switch for visually indicating that the fluid level in said reservoir has fallen below a predetermined level.
