Abstract

367,190. Grab - buckets. NAAMLOOZE VENNOOTSCHAP HAVENBEDRIJF VLAARDINGEN-OOST, Vlaardingen, Holland. Feb. 27, 1931, No. 6215. Convention date, March 1, 1930. Addition to 349,571. [Class 78 (iv).] In the grab according to the parent Specification the opening rope m, instead of passing round one of the pulleys on the toggle joint k, divides, and its ends, after passing round pulleys on a member m<11> carried by the togglejoint are fixed at m<1> to the grab-head, the dimensions of the system being such that when the opening grab reaches the position shown in the Figure (when the hinge c is at the same height as the hinges f) the opening effect will be replaced by a resilient braking effect. At the same time stops x prevent the toggle levers from approaching any nearer to the grab head. The closing rope arrangement is that shown in Specification 362,205.
