Abstract: A centrifugal blasting wheel includes a pair of front and back wheel plates interconnected in spaced parallel relationship. Each wheel plate has a central opening defined by an annular surface of constant diameter. These plates are provided with respective cross-wise aligned grooves in their inner faces extending radially in equally circumferentially spaced relationship from the inner annular surfaces of the plates to the outer annular surfaces thereof and opening into each of the annular surfaces. A blade is removably mounted between each pair of aligned grooves. Each blade has a body generally in the form of a parallelepiped with an inner and an outer end and side flanges to define a blade of I-shape in transverse cross-section. Each blade has at least one retaining lug extending laterally from one of the side flanges and being substantially closer to the inner end of the blade body than the outer end thereof.

Abstract: A bladed centrifugal blasting wheel formed of a pair of spaced parallel wheel plates having a central opening through which blades are inserted into grooves extending radially from the central opening through the adjacent surfaces of the wheel plates, improvements including means for locking the blades between the wheel plates, impeller and control cage means for feeding particulate material onto the ends of the blades with centering means forming a part of the impeller for locating the elements in the central opening, resilient means adapted to be engaged by the blades upon insertion for holding the inserted blades during assembly, indicator means for showing the position of the control cage and means for providing air curtain to prevent accumulation of stray or rebound abrasive in the hub seal area during rotation of the bladed wheel.

Abstract: A guard housing and liner for bladed throwing wheels, in which the guard housing is in the form of a trapezoidal section dimensioned to enclose the bladed wheel and a cover which fits onto the upper end of the trapezoidal section for pivotal movement between open and closed position and for removal from said trapezoidal section, and a liner formed of a plurality of interfitting sections lining the interior walls of the guard housing.

Abstract: A centrifugal casting machine comprising a support means having a housing pivotally mounted thereon about a horizontal axis to permit the housing to be tilted relative to the support means. A mold member is rotatably mounted within the housing and has a drive shaft connected thereto extending through the rearward side of the housing for connection to a power means such as an electric motor. The power shaft is provided with a bore extending therethrough to permit argon gas or the like to be furnished to the interior of the mold member to reduce the oxidation or the like to be furnished to the interior of the mold member to reduce the oxidation of the aluminum casting material. The casting material support stand is positioned forwardly of the housing and has a casting material hopper selectively vertically mounted thereon for supplying the casting material to the interior of the housing and mold member.

Abstract: In order to clean work pieces such as castings a work piece is loaded into a cage and continuously rotated while being continuously advanced past a means for propelling particulate cleaning means at the work piece.
