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.
Claims10
A brick molding apparatus comprising a horizontal conveyor, nesting pallets and brick forms traveling on said conveyor, a clay hopper positioned above said conveyor and having a bottom clay outlet at an elevation to deliver clay from the hopper directly into brick mold cavities of said brick forms, vibration means extending into the hopper to vibrate clay therein, clay feed means within the hopper to feed vibrating clay through said bottom clay outlet, a flapper blade pivoted to the bottom of the hopper adjacent said outlet and adapted to enter said mold cavities of the moving brick forms on the conveyor in succession and forcing the clay from said outlet into the forward part of each mold cavity before allowing the clay to fill the rear part of such cavity, said flapper blade adapted to ride over divider walls separating said mold cavities, and a vibrator means near the downstream end of the hopper for contacting each moving form in succession and imparting vibration thereto and including a strike blade element for removing excess clay from the top of each form.
