Abstract: A Hookes universal joint has each limb (5, 6) of its yokes provided at its free end with a removable portion (15, 115) which, when it is removed, leaves an opening to facilitate fitting of the respective journal (11, 111) of the joint cross member into the bore (9, 109) in the yoke arm. The removable portion and main part of the yoke arm have inter-engaging dovetail formations either of frusto-conical form (18, 19) or straight configuration (118, 119).

The necessity of providing the yoke arm with bores for fixing bolts, which would weaken it, is thus avoided.
