Abstract
224,586. Portway, A. P. Aug. 10, 1923. Securing hand - wheels on shafts.-A handle for adjusting an instrument such as a variable electric condenser or resistance is attached to the movable member of the instrument by a cup-like sucker 1, Fig. 2, of rubber or other flexible, material having a boss 2 reinforced by a rigid thimble or ferrule 4 of metal, vulcanite or other material. The ferrule 4 is secured by an arm 5 provided at the opposite end with a knob 6, and is attached to the boss 2 by a cross-pin 7. The sucker may be removed from the instrument by compressing its lip so as to break the vacuum. In a modification, Fig. 8, the arm is not secured to the ferrule 4 but is passed through a hole in the boss 2 and rests in grooves 4b in the ferrule. In this form the arm 5 acts as a lever.
