Heater without chimney nicely balanced by means of a counterpoise weight. On the other end of this arm there is a damper, suspended over the top of the heater, which opens and closes, thereby permitting the heat to enter the machine or to escape around the damper. Some thermostats regulate the size of the flame as well as the position of the damper. The position of the counter- poise weight is usually located at the factory, and seldom needs attention; but it should be so placed in point of balance that it will develop sufficient leverage to raise the damper which is hung at the other end, as soon as there is the slightest pull on the con- necting rod which leads to the thermostat. In other words, the damper or tin wafer over the heater should be a trifle heavier than the counterpoise weight, consequently lie fiat over the vent in the heater when the machine is cold. We are cautioned not to tam- per with the heat-regulating ap- pliance, which is good advice in a way, except that intelligent tampering, which amounts to ad- justing, is sometimes necessary. Occasionally the regulator arm is found bent out of line, if it is metal, or perhaps warped, if it is wood, in which case the alignment will have to be corrected, or the damper will not fall directly over the vent in the top of the. {Courtesy Buckeye Incubator Company) Fig. 158.—Complete gas heater for incubator or Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Roberts, Howard Armstrong, 1885-.
