bucket sections as they approach each other should travel for a considerable distance in substantially horizontal lines under the matcrial in which the bucket is working. By connecting the front end of each bucket-section through the links c c or c c to the upper portions (1 b of the links which control the movements of the rear ends of the opposing bucket l attain the desired horizontal travel of the bottom of each scoop or bucket section. In order to close the bucket, power is applied tlnough the ropes M M to the upper ends of the lovers B B, drawing them toward each other and at the same time causing their lower ends to swing inwardly, the travel of the rear ends of the buckets being controlled by the lower end of the lever to which they are connected, the course of travel of their front ends being controlled by the movement of the upper portion of the other lever transniitted through one of the said pairs of connecting-links C C C C.
