Abstract
To improve the structure described in my earlier U.S. Pat. No. 3,954,264, d permit release of the hook (8) upon excessive force being applied by a cross-pin (21) on the hook if an inadvertent or carelessly thrown bowling ball applied a force (G) to the bowling pin wiper blade (35), the hook support arm (4, 5) is formed in two arm portions (4, 5) with a buckle joint (13) therebetween spring loaded to maintain a slightly out-of-line position of the support arm, but permitting buckling if a downward force on pin 21 (FIG. 1) pushes upwardly the camming roller (7) at the lower end of the lower arm portion (5) against a force in spring (32) and thus prevent damage to the suspension arm (1), the support arm (4, 5) and the other components of the mechanism.
