SPRAYER WITH INTERCHANGEABLE POWER SOURCES

Title:

SPRAYER WITH INTERCHANGEABLE POWER SOURCES

Document Type and Number:

WIPO Patent Application WO2003059522

Kind Code:

A3

Abstract:

There are several components on the convertible gas/electric sprayer (12) that facilitate the easy electric motor/gas engine conversion and positioning of the pulley (18) to the drive belt (20) for loading and unloading. The pulley for the gas engine and the pulley for the electric motor have two features that help guide the drive belt (20) onto the pulley (18). The lead in angle (18A) on the front of the pulley (18) helps the belt (20) over the front of the pulley(18). The backstop lip (18C) on the rear of the pulleys prevents the belt (20) from overshooting the V-groove(18D). The fingers (22A) on the upper portion of the bracket hold the belt on the upper drive pulley during conversion and shape the belt to accept the drive pulley, and the rib (22B) on the bracket holds the belt in position to accept the pulley during loading.
