Abstract

394,605. Making cutting-chains. ANDERSON, A. and ANDERSON, BOYES, & CO., Ltd., Flemington Electrical Works, Motherwell, Lanarkshire. Jan. 17, 1933, No. 1476. [Class 83 (ii).] A pick-carrying block for cutter chains comprises two side plates 1, 1a formed integral with members 2, 2a respectively, each of which members constitutes half of the bridge between the side plates. A notch 3, 3a is machined in each of the members 2, 2a, the notches forming the inner wall or walls of pick sockets of non-circular cross section. The members 2, 2a are welded together and the sockets completed by welding to the members 2, 2a a member 4, preferably V-shaped, which is accommodated in the notches and forms the outer walls of the sockets. Specifications 388,333, and 390,784, [Group XXI], are referred to.
