Abstract

330,908. Denholm, T. D. March 18, 1929. Divided application. Scoop-arm machines.-In an excavating and loading machine of the back-digging type, the bucket e is pivoted at d to its arm b and one or more links g are adjustably connected to apertured brackets f on the bucket; the other ends of the links are pivoted to blocks pressed by shock-absorbing springs h. The arm b is connected by a chain l to a trolley i sliding on the boom a; the digging stroke is effected by moving the trolley by means of a rope r, while the return stroke is effected by means of a rope o.
