US Patent:

45612200, Dec 31, 1985

Filed:

Dec 13, 1984

Appl. No.:

6/681512

Inventors:

James H. Carpenter - Hagerstown MD
Ronald L. Mullins - Hagerstown MD
Ronald L. Smith - Hagerstown MD

Assignee:

Kennecott Corporation - New York NY

International Classification:

B24C 504

US Classification:

51427

Abstract:

This relates to a portable abrasive throwing wheel device or abrasive blasting device which is utilized for blasting 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 readily counteracted. The portable device includes a fixed motor and a fixed abrasive supply with a throwing wheel carried by the motor and only a housing portion 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.

Kennecott Corporation - Cleveland OH

International Classification:

B24C 506

US Classification:

51434

Abstract:

A throwing wheel assembly for providing an even discharge of impact blast material along the face of a vane is disclosed herein. An impeller positioned in a non-parallel relationship to the outer impeller casing is also provided in a spatial relationship which aids in providing an even flow of impact blast material to the vanes. A deflector plate is provided for directing stray blast material onto the vanes.
