Abstract: A coupling apparatus and method is disclosed for coupling a first hose for enabling the flow of a fluid therethrough, comprising a first coupling member having a first coupling internal bore extending between an inner end and an outer end. First coupling threads are defined in the first coupling member proximate the inner end whereas first coupling linking threads are defined by the first coupling internal bore of the first coupling member proximate the outer end. A second coupling member has second coupling threads defined therein. A first attachment member has first attachment linking threads with means for affixing the first hose attachment member to the first hose. The first attachment linking threads are engagable with the first coupling linking threads for securing the first hose to the first coupling means. The first coupling threads are engagable with the second coupling threads for interconnecting the first coupling member and the second coupling member for coupling the first hose thereto.

Abstract: An abrasive cleaning apparatus configured for use in combination with a mobile chassis comprising a base means including attachment means to fasten the abrasive cleaning apparatus to the mobile chassis, an adjustable nozzle support means to operatively support a plurality of nozzle means thereon and interconnecting boom means coupled between the base means and adjustable nozzle support means. The interconnecting boom means includes a first and second boom element arranged in telescoping relation relative to each other to permit linear adjustment of the adjustable nozzle support means relative to the base means and mobile chassis. The adjustable nozzle support means includes a first and second positioning means to permit movement of the plurality of nozzle means in a first and second plane respectively.
