Abstract

1307015 Shaft couplings C H ALLEN 16 March 1970 12495/70 Heading F2U [Also in Division F1] The coupling between a drive-shaft 19 and the rotor 12 of a rotary pump (see Division F1) comprises a link 22, bifurcated at one end 24 and connected to the shaft 19 and rotor 12 by means of a pair of parallel pivot pins 23, 25, thus permitting eccentric movement of the axis O-O of the rotor 12 at twice the rotational velocity of the rotor itself.
