of a pendulum. Comb members or jaws 41 may be
attached to the frame 4d in any suitable manner such as
by bolts and nuts or screws as shown at 46.
A cam member 47 is suspended through the frame 46
by means of a shaft 48.
After the cavity is ñlled with aggregate the electromagnet
54 -is deenergized, thereby demagnetizing the faces of the
lingers 56 to »release plates 21 from said lingers.

The plate holder is then removed `from the' mold cavity
and the brick `co-molded as described above.
In certain instances it may `be desirable to provide
shielding means 57 between the table surface 38 and the
handle means of the plate holder in order to minimize
dissipation of electromagnetic forces generated by the
electromagnet 54 and placed upon _the plate holder 53.

the cam 47 and lever 51 respectively. Said levers 51 are
attached at their distal ends to the shaft 43 by means of
the boss 49 as shown in FIGURE 14.

be held in position on fingers 56 by utilizing a vacuum
