Abstract: 23,994. Fowler, R. H., and Benstead, T. Oct. 30. Excavating.-In a travelling implement for displacing earth, comprising a scoop carried by a frame which is drawn over the ground by a hauling - engine, the scoop when full is raised to positions for carrying the earth and discharging the same by the tension of the hauling-rope. As shown in Figs. 1 and 2, the implement consists of a main frame a, which is mounted on rollers b, c and is drawn over the ground by a rope wound over a drum m locked by a spring catch p. The scoop e is suspended from the frame a by links x, and is pivoted to an underframe d also suspended from the frame a. This underframe may carry cultivating-tools f for loosening the earth. The drum m is keyed to a shaft l, which also carries two smaller drums n at the sides. Chains o extend from the smaller drums to the front of the scoop e, so that, when the shaft l is rotated, the chains will raise the scoop. Attached to the rear of the underframe d is a plate g forming the back of the scoop. In operation, the frame a is drawn over the ground until the scoop e is full, and the catch p is disengaged ; the tension on the hauling-rope then causes the drums m, n to rotate once, thereby raising the scoop to a midway position suitable for carrying the earth. The implement is then drawn to the place for discharging the earth, and the catch h is again released, whereby the scoop is raised to the position shown by the dotted lines in Fig. 1, and the contents are discharged. When the implement is required to turn round, a forked lever r is provided with guide-pulleys s for the ropes, which turn the implement on the rollers b as a pivot. The inclination of the scoop to the ground may be varied by turning a spindle, which operates a lever h bearing on a rearward extension e<2> of the scoop.
