Abstract
Apparatus for treating workpieces with gravity accelerated shot in which the workpieces are impacted by the impingement of the shot. The apparatus includes unique means for handling the shot to cause it to freely fall and impinge uniformly on the workpieces. This unique means includes the provision for two chambers arranged back-to-back, one containing an elevator assembly which elevates the shot upwardly to the top of the other impact chamber which includes a bucket assembly for catching the shot. The uniformity of the shot stream is created by providing a perforated plate or screen and controlling the depth of the shot above the screen.
