Abstract

700,422. Angular bending. CHAMBERLAIN, A. G. Jan. 22,1952 [July 19, 1951], No. 17179/51. Class 83 (4) In a reciprocating bender abutment rolls 2 are removably carried on arms 3 positioned in use by abutments 25. and foldable when not in use against a jack cylinder 8. The arms 3 and the abutments are mounted on a bender 4 of the jack. Liquid is pumped from a reservoir 9 by a pump 27 with operating lever 17 pivoted on a lever 38 to move the ram 7 with attached former head 24. The ram is withdrawn by spring or hand means.
