Abstract

A portable electric heating system. This device consists primarily of plug in units having heating elements controllable manually and automatically. The circuit consists of a multiple number of manual and motor operated switches with a battery power pack for supplying current to the plug in units.

Claims

1. An electric device for heating certain portions of the body of a wearer, comprising:

a. An electric current source including a plurality of electric cells;

b. means for connecting the electrical current source to at least one of the heating units positioned about the torso of the wearer;

c. means for connecting the electrical current source to at least one of the heating units positioned adjacent the sole of each foot of the wearer;

d. a plurality of switches and a motor operated by the electric current source for automatically operating the switches for energizing and de-energizing the said heating units at predetermined intervals;

e. means for disengaging said motor from the electrical current source and manually operated means for operating electrical switches for energizing and de-energizing said heating units. f. said foot heating elements having a plurality of heating units extending along the sole of the foot of the user and means for energizing the units individually or separately.
