ABSTRACT:
An adapter consists of a more or less cylindrical body having a rear outer portion and a front inner portion, projections (or other suitable coupling means) on the rear outer portion for effecting the coupling to an automatic adjusting device, and at least three different recessed configurations located at different depths within the body's front inner portion for mating respectively to at least the three most common types of residential thermostat knobs. The most recessed configuration receives the smallest such knob, which is of the "lever" type. The middle configuration is a circular ring of inwardly projecting teeth for engaging the intermediate size "serrated" type of knob. The least recessed configuration is of an internal bevelled shape for receiving the largest such knob, namely the "bevel" knob. These various recessed configurations are so located and dimensioned with respect to the body of the adaptor to allow each type of knob to reach and mate with its corresponding recessed configuration.
