Abstract
448,179. Cutter chains for mining. MINING ENGINEERING CO., Ltd., Meco Works, Worcester, and MOORE, M. S., Ivanhoe, Worcester Road, Malvern, Worcestershire. Oct. 23,1935, No. 31709. [Class 68 (i)] [See also Group XXV] In a mining machine cutter-chain, the side links 3 are pivoted on pins 2 projecting laterally from the pick boxes 1 and have inward extensions 4 adapted to bridge the gap between the links to keep out cuttings from the chain guide and also to engage the ends of the pick boxes to give a stiff-back chain. The extensions 4 may be connected together as by rivets or welding. The ends 6 of the extensions may be bevelled &c. to engage corresponding surfaces on the pick boxes to prevent sidewise rocking. The links 3 may have sharp corners 8, and the boxes 1 may have projections 9, to scrape the bottom and sides of the chain guide.
