ABSTRACT:
Apparatus for suppressing noise generated by a concrete or the like block making machine having a vibratable open bottom mold against the bottom of which the pallet is clamped to close the mold and provide a support for the molded block. The pallet support and the mold are sandwiched between yieldable, compressible, opposed force applying members which clamp the pallet to the mold and maintain the mold in a state of suspension during its vibration. The clamping of the pallet to the mold and the suspension of the mold greatly minimize noise generated by vibration of the mold.
