IMPROVED THROWING BLADE CONNECTION ASSEMBLY FOR ABRASIVE THROWING WHEEL

摘要

An abrasive throwing wheel assembly includes a runnerhead which includes radially extending dovetail shaped channels. In one embodiment, the channels each have a slot. A throwing blade includes a throwing portion and a dovetail shaped base portion removably received within a channel. In one embodiment, the base portion includes a slanted surface at a same angle as the slot relative to the axis of the channel when inserted within the channel. A U-shaped locking pin received in the slot prevents radially outward movement of the throwing blade. In another embodiment, the channels include an L-shaped slot in a surface thereof and the base portion of the throwing blade includes a slanted surface and a locking face, the locking face is perpendicular to the surface and parallel to a longitudinal axis defined by the throwing portion. An L-shaped locking pin received in the slot secures the base portion in the channel.
