If desired, suitable stops may be provided to positively force the damper to the closed or open position at the limits of rotation of knob I2. It will be apparent that as the knob is turned in one direction it will curl the bimetallic strip so as to make opening of the damper more difficult, that is require more heat to effect opening. By suitably calibrating the portion of jacket 8 in the vicinity of knob l2 a visual indication of whether the shaft or damper has been turned to the high or low position is given. Knob I2 is mounted exteriorly of jacket 8. One end of the bimetallic strip is connected to rod 1 and the other end to the lug H) which, in turn, is connected to the outer part of rotatable arm H, which arm is rigidly fixed to the shaft of knob I2. Within the top portion of the downflow air pipe 4 is mounted a damper 6 supported on rod or'shaft l, which rod is rotatably mounted Within the space between downtrated as being of spiral design, it being understood, however, that other designs of thermostats are equally suitable. At the top of downflow air pipe 4 is a cap 5 having a plurality of holes 5 which constitute the sole opening in the stove for admitting cold air. Referring more particularly to Figure 1, numeral l denotes an airtight wood burning stove supported on legs 2 and having the conventional smoke flue or draft outlet pipe 3 anddown'fiow air pipe 4.
