Abstract

983,169. Linkwork. DAVID ETCHELLS (MACHINERY) Ltd. July 25, 1963 [Aug. 22, 1962], No. 32182/62. Heading F2K. [Also in Division B3] An upsetting machine has a reciprocating tool slide 11, a stationary work-gripping jaw 12, and a movable work gripping jaw 14 mounted on a slide 15 actuated through toggle linkage 16, main link 27, auxiliary link 28 and rocking lever 25, the auxiliary link 28 being normally almost in line with the main link and prevented from passing through a dead centre position and the arrangement being such that upon obstruction of the moving jaw 14, the rocking lever 25 will cause the auxiliary link 28 to pivot about its connection with the main link, Fig. 3, without operating the toggle linkage 16. The slide 11 carries a heading tool 13 and is actuated by connecting rod 18 and crank 17 driven through belt 22 by motor 20. The connected rod 18 is also coupled by link 24 to the rocking lever 25 such as to provide closed and open dwells for the gripping jaw. Auxiliary link 28 is normally held with its rocking lever pivot against an abutment 29 on the main link, Fig. 2 (not shown), and is also connected to the main link by a fluid cylinder and piston device 30, 31. Thus any obstruction of the moving jaw 14 causes the auxiliary link to pivot away from the abutment 29, Fig. 3, without operating the toggle 16. If the machine is stopped with the jaw 14 not in its fully raised position, the cylinder and piston device 30, 31 is operated to move the jaw into this position and also prevent its operation by the rocking lever. The latter may alternatively be actuated by a rotary cam on the crank-shaft.
