Abstract
1,222,767. Filling moulds. W. SCHNEIDER, and K. SCHNEIDER. 13 Nov., 1969 [21 Nov., 1968; 22 May, 1969; 7 June, 1969], No. 55517/69. Heading B5A. Concrete elements are formed in a mould 10 divided into a plurality of separate compartments which fit flush into an opening in a table top 12 from a predetermined quantity of concrete mix. To fill the mould, concrete is swept across the open top of the mould on to the table beyond the mould, while at the same time the mix is displaced sideways at right angles to the direction of sweep and the remainder of the mix is then swept back with simultaneous reversal of the horizontal sideways displacement. The table 12 carries two rails 14 on which the filling box 30 runs. Concrete is supplied from hopper 24 to the filling box 30 and some passes through a grid of metal strips 40, 41. As the filling box moves across the moulds, deflecting plates 42, 44 and metal tabs 43, 45 force some of the concrete sideways to fill the moulds evenly, the deflecting tabs and angles acting to deflect the concrete sideways in the the opposite direction as the box returns to its starting position. The mould supporting table 16 may be vibrated by vibrators 18, and the filling box may be subjected to small amplitude oscillations along the direction of rails 14 when it is over the mould and nearer to the side remote from the feed hopper. The concrete may be compacted by rams 20 equipped with vibrators and the ends of the rams may comprise plates 120 with a central tapered hole formed by downward extensions 150, through which excess concrete is forced.
