Abstract: Brick forms on stackable pallets are delivered in succession by a conveyor belt beneath the outlet of a clay hopper equipped with an internal vibrator and a clay feed auger. A pivoted flapper blade trips over each brick form divider wall and assures that the clay is forced first into the forward part of each mold cavity. Water is supplied to the front face of the flapper blade. Immediately beyond the hopper outlet, a diaper assembly having a mechanical vibrator engages each moving form to vibrate the clay and promote random clay crystal orientation. A strike blade on the diaper assembly removes excess clay and water from the top of each moving form. Water is also supplied constantly to the strike blade.
