Abstract

681,293. Angular bending. ASH, R. FREER-. March 14, 1951 [March 14, 1950], No. 6311/50. Class 83 (iv). In a reciprocating bender with abutments q, a former n is mounted on a Z-shaped member h moved by a ram m of a fluid cylinder k in order to reduce the length of the machine. The member h has a leg h<SP>1</SP> projecting through a slot g in a table d to which the former n is secured. Guide members j locate the member hand support the cylinder k. A hand lever r actuates a pump.
