US Patent:

42493501, Feb 10, 1981

Filed:

Jan 15, 1979

Appl. No.:

6/003689

Inventors:

James R. Goff - Oklahoma City OK

International Classification:

B24C 506

US Classification:

51434

Abstract:

A combination comprising a blade block for mounting on an abrasive throwing wheel and a blade for mounting on the blade block is provided. The blade has a front surface and a rear surface, a first opening on the rear surface and a second opening on the rear surface spaced from the first opening. The blade block is provided with projecting means, such as a lug, adapted for insertion in the first opening on the rear of the blade. An abutment means contacts the rear of the blade. An opening in the blade block is provided, and the opening is intermediate the projecting means and the abutment means on the blade block. The blade is held in position on the blade block by locking means, such as a deformable, resilient wire, adapted for insertion in the second opening on the rear of the blade and for insertion in the opening in the blade block. The assembly comprised of the blade block, throwing blade and locking means is particularly useful in a rotatable, centrifugal, abrasive throwing device of the type frequently used for throwing sand, metal shot and other particulate material onto a surface to be cleaned.

Filed:

Apr 21, 1975

Appl. No.:

5/569727

Inventors:

James R. Goff - Oklahoma City OK

International Classification:

B24C 306

US Classification:

51 9M

Abstract:

An improved abrasive throwing machine comprises an enclosure having means therein for projecting abrasive particles at an inclined angle relative to a surface to be treated. The improvement comprises rotatable means within the enclosure capable of propelling spent abrasive particles that rebound from the surface, and returning such particles to the projecting means. The rotatable means is typically a brush of substantially circular cross-section. The apparatus is especially well suited for cleaning substantially flat, horizontal surfaces, such as the tops of storage tanks, decks of naval vessels, roadways and aisleways.

Appl. No.:

6/046740

Inventors:

James R. Goff - Oklahoma City OK

International Classification:

B24C 506

US Classification:

51434

Abstract:

A blast wheel for a rotatable centrifugal abrasive blasting device comprises a wheel having a front surface and a rear surface. A plurality of radially extending abrasive throwing blades are substantially equally spaced around the circumference of the front surface of the wheel. A vaned impeller is also on the front surface of the wheel. A ring is rigidly secured to the rear surface of the wheel. The blast wheel is a one-piece casting formed of dissimilar materials, such that the wheel, blades and impeller are formed of an abrasion-resistant material having relatively poor machinability. The ring is formed of a material having good machinability. The blast wheel is useful for projecting an abrasive, such as metal shot, against a surface to be treated.
