supported by flanged rollers 14 (Figs. 2, 3, 7 and 8).
Lifting and supporting bars 35 (links of I-section), located
in the spaces between the conveyor members, are carried by
blocks 37, cross beams 38, and rods 39. The lifting and
supporting bars function to raise and support a load above the
conveyor bars until the return movement of the conveyor bars
is completed, when the load is again deposited on the conveyor
bars.
The Abraham patent teaches a conveyor transfer system
used in a foundry (Figs. 1, 2, and 12). Molds are movable
between a first path 14 and a second path 16 via shuttle
conveyor 20. Horizonal beams 240, 242, outboard of support
members 204, 206 (Fig. 12), are supported on rollers 254, 256
and are horizontally movable, while support members 204, 206
are mounted for vertical movement. Molds are transferred to
and from the shuttle conveyor.
The Foster ‘686 patent addresses a reciprocating floor
conveyor with groups of independent floor members 1, 2, 3 that
