Another object of my invention is to provide a means for, and method of, disposing metal plates within the interior of a brick prior to compression of the brick. ‘ A still further object of my invention is to provide FIG. l5; FIG. 17 is a section taken along line l7-~1i7 of FlG. 15; and FIG. 18 is a section taken along line 1S-~-13 of FIG. 15. Referring now -to the drawings, FIG. l _shows a per spective view of a co-molded brick 2d having plates 2l therein. The plates 21 may be solid, perforated or ex a means for, and method of, disposing metal plates within the interior of a brick prior to molding of said brick and without distortion of said metal plates. Another object of my invention is to provide a means panded metal. Other advantages brought about by my invention will become apparent from the following specific description thereof in connection with the accompanying drawings jaws 31 have benerally U-shaped slots 29 for the recep tion of plates 21. Said U-shaped slots form vertically in which: FIG. 1 is a perspective view showing co-moldcd brick with outline in phantom; FIG. 2 is a side elevation of plate holder fixture with 35 for reception of metal plates across their face. Lips 35 may be provided at the terminal portion of said fingers and said U-shaped slots in order to more effectively hold FIG. 2 is a side elevation of my plate holder fixture which is generally designated as 22. in this view the fixture is shown with plates in the holder, said holder for, and method of, placing metal spacer plates within being within a brick mold cavity 23 prior to the intro the interior of a brick prior to molding of the brick and duction of aggregate into the cavity.

A filler box 25 is shown in dot While bricks have been made with metal `spacer plates and dash outline in FlGS. 2 and 3; said box being the therein, no economical and expeditious method has heremeans for placing a measured amount of aggregate in tofore been known whereby such spacer plates may be the brick mold cavity 23. easily and efficiently placed within the interior of a 1orick Referring more particularly to FlG. l1, my plate holder mold cavity prior to the introduction of brick aggregate comprises a frame 26 to which is rigidly attached handle into the mold cavity. In the usual method of introduc members 27. A first plate holding comb 28 is rigidly ing metal spacer plates within the interior of a brick, attached to the handle members 27 and to the frame it has been customary to force the plates into the aggre 26. Said comb is provided with generally U-shaped gate after the mold cavity has been filled with brick slots 29' for the reception of plates 2ï. The first plate aggregate.
