Abstract
891,857. Trench - excavating machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 15, 1960 [June 15, 1959], No. 20519/59. Class 68(1). Peripherally spaced around and loosely secured to or hinged between spaced apart discs 15 rigidly secured to a shaft 7 that can be driven at high speed are chains 16 or plates which, as the shaft is rotated, fly out under centrifugal action to act as flails to strike the ground at right angles to the direction of advance of the vehicle from which the frame 2, 3, 4 carrying the shaft 7 is supported. These flails are particularly suitable for excavating or cleaning drainage ditches.
