Abstract

699,419. Pistons. GRANDORI, C. Jan. 8. 1951 [Jan. 23, 1950], No. 512/51. Class 122(i) [Also in Groups XXVIII and XXIX] In a concrete pump (see Group XXVIII), the piston comprises a disc 8 connected by a longitudinal member 11 to a disc 10 and packing 8<SP>1</SP>, 11<SP>1</SP> partly surrounds the discs 8, 10 and continues along the edges of the longitudinal member. The piston has a further longitudinal member 9<SP>1</SP> that is guided between longitudinal ribs 34 on the cylinder.
