Abstract

1,022,829. Guiding loading receptacles. ETABLISSEMENTS R.G.A. Feb. 17, 1964 [Feb. 22, 1963], No. 6481/64. Headings B8B and B8E. A device for engaging a bucket 3, Fig. 3, being lowered or raised by a crane and for automatically guiding the bucket under the discharge shoot 18 of a concrete mixer comprises a lever 6 pivoted on a horizontal axis 4 and carrying a dish-shaped recess 7 for engagement with a projection 17 on bucket supporting cable 16, the arrangement being such that the weight of the bucket 13 causes the lever 6 to tilt downwards and thereby move the bucket laterally towards and under the discharge shoot. The lever 6 has resilient guides 8 arranged in V-formation leading to an entry slot for the cable in the region of the recess 7. The arm 6 is normally held horizontally by a weight 12 attached to a rearward projection 10. A parallel linkage system 21, 23, 24 maintains the recess 7 horizontal as the arm 6 tilts. The movement of the arm may be associated with a switch controlling the discharge from the concrete mixer so that discharge is prevented unless. the arm is down.
