Abstract
306,260. Henriques, W. Q. Jan. 25, 1928. Scoop-arm machines.-In an excavator or dredger, comprising a bucket or shovel carried on one or more dipper arms, the bucket is supported on a member which is slidable on the arm or arms, resilient means being arranged between the bucket and arm or arms to take up shock. As shown, the bucket 38 is secured to a casting 9 which is slidable on guide plates 8 between spaced, metal-cased, wooden arms 1, 2; a casting 18, fixed between the arms, carries an anchor rod 21 which extends through a circular bore 24 in the casing 9. Rubber and metal discs 25, 26, are arranged alternately in the bore 24, and at opposite ends of this assembly are placed plates provided with tubular extensions 28, 33, which surround the rod 21 and extend through the end walls of the bore 24 so as normally to contact respectively with a shoulder 22 and nut 36 on the rod 21. In a modification, the slidable casting carrying the bucket has on each side of the dipper arm a cylinder containing a spring buffer device, the anchor rods of these buffers being secured by links to opposite ends of a pin which passes transversely through the dipper arm The Provisional Specification describes buffer devices employing coil-springs.
