Abstract:  
This relates to a portable abrasive throwing wheel device or abrasive blasting device which is utilized for blasing castings and the like to effect the cleaning thereof. The portable device is of such a construction whereby its total weight is on the order of 100 pounds and is so suspended wherein it has very little thrust reaction on an operator so that it may be readily manipulated. Further, the principal thrust of the device is carried by the suspension for the device and otherwise is directed towards the operator so that it may be realily counteracted. The protable device includes a fixed motor and a fixed abrasive supply with a throwing wheel carried by the motor and only a housing protion being movable. The housing is rotatable about the axis of the motor and serves to permit the discharge opening of the device to be tilted to the desired angle for directing the abrasive blast where desired. Several abrasive supply systems are provided as are several mountings for the portable device.
