Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
A combination die and pallet assembly upon which mortarless interlocking cementitious blocks are cast and subsequently transported, said combination die and pallet assembly comprising: (a) a die and pallet plate having top and bottom planar surfaces, said die and pallet plate formed of solid heavy gage metal having a thickness dimension of at least one-quarter inch and having a plurality of apertures formed therethrough with those apertures arranged in a predetermined array; and (b) a backing plate of planar configuration in contiguous engagement with the bottom planar surface of said die and pallet plate during block casting operations and separable therefrom for subsequent block transport.
