Expandable air hose

An apparatus for operating a pneumatic tool, comprising:

• an air compressor;
• an expandable air hose having a collapsed state and an expanded state;
• said air hose having a proximal end and a distal end;
• said proximal end of said air hose connected to said air compressor for receipt of compressed air;
• belt plies and metal cords that run longitudinally along said expandable hose;
• said distal end of said expandable air hose connected to a pneumatic tool for supplying compressed air thereto;
• said expandable air hose being in said collapsed state when said air compressor is not engaged and having said expanded state when said air compressor is engaged to pressurize said expandable hose and cause operation of said pneumatic tool.

A process for providing compressed air from a compressor to a work tool comprising steps of:

• providing an expandable air hose in a collapsed state;
• said expandable hose having radial plies comprising polyester cords running perpendicular to the length of said expandable hose;
• connecting an end portion of said expandable air hose to an air compressor;
• connecting the other end of said expandable air hose to a pneumatic tool;
• engaging said air compressor so as to force compressed air into said expandable air hose in a collapsed state thus causing said expandable air hose to expand into an expanded state, said compressed air engaging said pneumatic tool to cause motion therein;
• disengaging said air compressor from said expandable hose;
• permitting compressed air to escape from said expandable air hose;
• causing said expandable hose to collapse and resume said collapsed state.
