ABSTRACT:
A hammer is provided which is useful in solid waste, e.g. metal, shredding operations. The hammer includes a shank member adapted to be connected to a supporting shaft, and a replaceable tip member which is subject to wear substantially along its leading and lower portions. The shank end and the tip are slidably interconnected along a common face, e.g., by a tongue and groove interrelationship. Cooperating keyway pocket and hooked key interconnecting means are provided on the shank and on the tip, with a significant portion of the keyway pocket/hooked key interengagement being in the shank. A slot passes through the shank and the tip adjacent the trailing edge thereof. A wedge is inserted into the slot. Finally, means are provided for retaining the wedge in the slot. In this way a tip member is provided which is very easily replaced when worn.
