Abstract
Apparatus for joining a tooth to an interlocked adaptor of a construction tool having a keyway passing through the interlocked tooth and adaptor. An L-shaped elongated key is inserted into the keyway so that the two sides of the key form a channel with the keyway which is filled with an elastic filler material. The key also has recessed areas which form recesses with the keyway which are also filled with the elastic filler material. One end of the key contains a plug to prevent the filler material from passing out of the channel.

Apparatus for joining a tooth to an adaptor that is mounted upon a construction tool that includes:
- a tooth that is interlocked with an adaptor so that a section of the tooth overlays the adaptor in an interlocking zone,
- a keyway passing through the tooth and the adaptor in the interlocking zone, an elongated key that complements the shape of said keyway that is insertable within said keyway,
- said key being curvilinear along its length and having an L-shaped cross section,
- the thickness of the key increasing from one end to the opposite end thereof,
- said key further including recessed areas for receiving therein an elastic filler material when said key is fully inserted within said keyway and wherein said one end of said key containing a plug means for closing against the inner wall of the keyway to prevent said elastic filler material from passing between said one end of said keyway and the inner wall of the keyway.
