(under subclass 419) Apparatus wherein the mechanism which aids loading or load distribution consists of a front gate or short ramp which normally closes the front of the scoop to retain the load.

(1) Note. The "apron" aids loading or load distribution by performing a hoeing motion to engage the earth being excavated as the scoop moves along and then pulling it up

into the scoop. [figure] [caption]A - Bowl; B - Digging edge; C - Rear wheels; D - Tractor; E - Draft frame; F - Draft arms; G - Loading mechanism; H - Apron
