Abstract

267,210. Edmonds, E. H: Dec. 8, 1925. Trenches, making by ramming soil. - A machine for making drainage channels in land without ejecting soil therefrom comprises a wheeled frame, a rotatable drum having a knifeedged ridge extending around it, and means for lifting the drum by power derived from one of the travelling wheels. The drum a is mounted in pivoted levers c, which may be weighted. The ridge a<1> is V-shaped in section. The rear ends of the levers c are supported by a lifting drum or cord h connected to a winding-roller j adapted to be driven when required from one of the travelling wheels through chain gearing m, n, o and a spring-controlled clutch k. The drum is raised on engagement of the clutch k by means of a hand-lever q. The clutch is disengaged automatically by a rod l when the drum is raised far enough. The drum falls when a locking-pawl is disengaged from a ratchet-wheel s by means or a connecting-rod and a hand-lever p near the driver's seat.
