Abstract

1448574 Moulding concrete beams W ROTH [trading as MAX ROTH KG] 28 Aug 1973 [28 Aug 1972] 40419/73 Heading B5A Apparatus for moulding concrete beams of the kinds shown in Figs. 1 and 2, comprises a slidable mould or former 1, Figs. 3 and 4, which moves along a base on which the beam is moulded, a feed hopper 2, a series of transversely spaced partitions 3, pressure plates 7 and impeller means for feeding the concrete from the hopper into the mould cavity defined by the base, the partitions 3 and plates 7. A vibrator 9 imparts vibrations to the partitions 3 and plates 7 through a mounting plate 10. The leading end of each partition is pointed and may be inclined. The impeller comprises a piston 12 which moves parallel to the base. In another example the piston has an inclined reciprocating path. In another example the impeller comprises a pivotal hopper closure member. Both reciprocal and pivotal members may be used. In another example, Fig, 5, the impeller comprises reciprocating hopper closure members 14, 15 and a piston 12 which in another embodiment is omitted. The impeller may comprise two rotary propellers or a screw in the hopper outlet. In another example, Fig. 14, the feed-impeller comprises a four-armed rotor with shovel members 30. In this example two sets of vibrating plates 7, 7<SP>1</SP> are provided. If desired, a second hopper may be located between the vibrating plates.
