Abstract: Implements, such as landscape rakes, having chains with removably connected bars with teeth connected thereto are normally easier to service. The disclosed apparatus and method is an implement, such as a rake, that comprises a housing having a first-side portion and a second-side portion, a shaft rotatably supported by the housing, the shaft having a first end and a second end, a first member operatively connected to the shaft, and at least one bar removably connected to the first member.

Abstract: A melting method and a melting crucible assembly involve positioning a disposable (non-reusable), self-supporting refractory liner body in a refractory host crucible and melting a metallic charge in the liner residing in the host crucible. The melted metallic charge is poured from the refractory liner body, and the used refractory liner body is removed from the host crucible for discarding and replaced with a clean, new (unused) refractory liner body in the host crucible for melting the next metallic charge therein.
