Abstract

1,211,462. Bucket excavators. SVENSKA HYMAS A.B. 27 Sept., 1968 [28 Sept., 1967; 17 May, 1968], No. 46036/68. Heading E1F. Digging teeth 3 in an excavating bucket 1 are subject to impact from leaf springs 8 which are driven to oscillate a free end thereof disposed adjacent the teeth. The springs are mounted at their centres and are operated by motor driven cranks 29, and the free ends of the springs engage in solts in hammers 16 supported by pivoted arms 14. The springs may be operated instead by piston and cylinder devices. The teeth have a pin-and-slot connection with the bucket. In a second embodiment, Fig. 3 (not shown), the teeth are spring-loaded, and the springs are driven by an eccentric. Hydraulic or pneumatic stop means may inhibit hammer movement when the teeth are out of contact with the Surface being worked. The springs are preferably operated at a speed just above the natural frequency of the spring-hammer combination.
