Throwing blade connection assembly for abrasive throwing wheel
First Claim
1. An abrasive throwing wheel assembly, comprising:
- a housing;
a runnerhead disposed within the housing and arranged to be rotatably driven by a drive shaft about a center rotational axis, wherein the runnerhead comprises a plurality of radially extending dovetail shaped channels arranged on a face of the runnerhead, each channel including a slot extending at an angle relative to a radially extending longitudinal axis of the channel;
a throwing blade including a throwing portion and a dovetail shaped base portion configured to be removably received within one of the plurality of dovetail shaped channels, wherein the base portion includes a slanted surface configured to extend at a same angle as the slot relative to the radially extending longitudinal axis of the channel when inserted within the channel; and
a U-shaped locking pin sized and configured to be removably received in the slot to secure the base portion of the throwing blade within the channel, wherein when the base portion of the throwing blade is received within the channel of the runnerhead and the locking pin is received in the slot, the locking pin contacts the slanted surface to prevent radially outward movement of the throwing blade.

Abstract
An abrasive throwing wheel assembly includes a runnerhead disposed within a housing and arranged to be rotatably driven about a center rotational axis. The runnerhead includes a plurality of radially extending dovetail shaped channels. In one embodiment, the channels each have a slot extending at an angle relative to a radially extending longitudinal axis of the channel. A throwing blade includes a throwing portion and a dovetail shaped base portion configured to be removably received within one of the plurality of dovetail shaped channels. In one embodiment, the base portion includes a slanted surface configured to extend at a same angle as the slot relative to the radially extending longitudinal axis of the channel when inserted within the channel. A U-shaped locking pin is configured to be received in the slot to prevent radially outward movement of the throwing blade. In another embodiment, the runnerhead channels include an L-shaped slot in a back surface thereof and the base portion of the throwing blade includes a slanted surface and a locking face, the locking face being arranged perpendicular to the slanted surface and substantially parallel to a radially extending longitudinal axis defined by the throwing portion. A substantially L-shaped locking pin is configured to be received in the slot to secure the base portion of the throwing blade within the channel.
