ABSTRACT:
A hand or mechanically powered tamper tool which has a removeable, replaceable, tool head assembly. The tool head assembly is a separable component from the upper section of the tamper tool which consists of the mounting plate and its attached tamper handle. The tool head assembly has a rubber or similarly resilient material pad bonded to the underside of a backing plate. Connection elements, such as bolts, are permanently secured between the pad and the backing plate. The bolts extend through and are upstanding from the backing plate. The bolts are configured to then extend through openings in the tamper mounting plate, where nuts are used to secure the tool head assembly to the mounting plate. The tool head assembly is thus removeable from the mounting plate and its handle or supporting element and allows for the simple and ready replacement of a used and worn tool head assembly with a new tool head assembly.
