Abstract

1,214,842. Reciprocating concrete pumps. WINGET Ltd. Sept.11, 1968 [Oct.11, 1967], No.46416/67. Heading F1A. A reciprocating concrete pump comprises two piston/cylinder assemblies 12, 14 a concrete storage hopper 1 having an outlet 2, 3 communicating through a flexible hose 2A, 3A and a slide valve 6A with one of the piston/cylinder assemblies whilst the other assembly is connected through the valve with a delivery line 15 and vice versa, the hose being connected with the slide member 6 of the slide valve so as to move therewith. The hose 2A, 3A is made from rubber or synthetic rubber and the valve member 6 is operated by an air or hydraulically operated cylinder (6B) Fig. 3 (not shown). The valve member 6 slides in the valve body 10 and in one operative position the piston 16 on its suction stroke draws cement via opening 9 and hose 2A from outlet 2 into cylinder 12 and simultaneously piston 17 discharges concrete via opening 8 to the delivery line 15. Hose 3A is then blanked off. In the other operative position, as shown in broken outline, concrete is discharged from cylinder 12 and simultaneously piston 17 draws concrete from outlet 3; In another embodiment, Fig. 4 (not shown) there are only two flexible hoses (2B) and (3B) and a single delivery line 15. Alternatively Fig. 5 (not shown) comprises a single outlet 18 from the hopper and two delivery lines 23, 24 and Fig. 6 (not shown) shows another embodiment which is similar to the latter but has only two flexible hoses.
