摘要：
A PACKER HEAD CONCRETE PIPE MACHINE FOR MAKING A CYLINDRICAL PIPE IN AN UPRIGHT MOLD. CONCRETE IS MOVED FROM A HOPPER BY A CONVEYOR INTO A FEEDING DEVICE POSITIONED ADJACENT THE TOP OF THE MOLD. A ROTATABLE PACKER HEAD IS CARRIED UPWARDLY WITH A VERTICALLY MOVABLE CARRIAGE TO PACK THE CONCRETE AGAINST THE CYLINDRICAL MOLD TO FORM A CYLINDRICAL PIPE. THE FEEDING DEVICE HAS A CONESHAPED FUNNEL MOUNTED IN THE TOP TABLE FOR DIRECTING THE CONCRETE INTO THE TOP OF THE MOLD. A RING CARRYING A PAIR OF SCRAPER BLADES MOVES AROUND THE CONE-SHAPED FUNNEL ON OPERATION OF A FLUID MOTOR TO PUSH THE CONCRETE INTO THE MOLD.
