ABSTRACT:
There is disclosed a slip clutch useful for the fixed adjustability of an indexed knob on a control shaft of a device such as thermostatically controlled gas valve for a water heater. The clutch comprises the assembly of a shaft with a reduced end portion to provide an annular distal shoulder, a ring received over the end and having a radial tab, a spring washer also received over the end of the shaft and resiliently biasing the ring against the annular shoulder and an outwardly flared end of the shaft to secure the assembly. The end of the shaft is hollow form and has internal wrench flats so that the shaft can be immobilized and the ring rotated about the shaft. The control knob is received over the ring and has a radial slot which receives the radial tab.
