Throwing blade connection assembly for abrasive throwing wheel

A throwing blade for an abrasive throwing wheel assembly having a housing and a runnerhead disposed within the housing, the runnerhead arranged to be rotatably driven by a drive shaft about a center rotational axis and including 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, the throwing blade comprising:

• a substantially planar throwing portion;
• and
• a dovetail shaped base portion configured to be removably received within one of the plurality of dovetail shaped channels of the runnerhead, 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 wherein the slanted surface is configured to engage a U-shaped locking pin removably received in the slot whereby the base portion of the throwing blade is secured within the channel.

A throwing blade for an abrasive throwing wheel assembly having a runnerhead disposed within a housing and arranged to be rotatably driven by a drive shaft about a center rotational axis, the runnerhead including a plurality of radially extending dovetail shaped channels arranged on a face of the runnerhead, each channel including an L-shaped slot in a back surface thereof including a first portion extending radially and a second portion extending perpendicular to the first portion, the throwing blade comprising:

• a throwing portion;
• and
• a dovetail shaped base portion configured to be removably received within one of the plurality of dovetail shaped channels of the runnerhead, wherein the base portion 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, and wherein the slanted surface is configured to engage an angled surface of a substantially L-shaped locking pin when the base portion is received in the channel and a leg of the L-shaped locking pin is removably received in the second portion of the slot to secure the base portion of the throwing blade within the channel.
