Abstract

See full text

A combined extendable pole and counterbalance system for washing the windows of a building includes an elongated pole including a handle portion adjacent the lower end thereof and a window cleaning utensil adjacent the upper end. The handle portion is adapted to be grasped by a workman while standing on the ground. An elongated flexible line is suspended from the roof or some other an upper part of the building above the windows to be washed. The line extends downwardly toward the ground and is connected to the pole. A spring driven drum biases the line upwardly thereby lifting part of the weight of the pole. The line is preferably connected to the pole adjacent the handle portion thereof but passes around and is guided by a pulley located adjacent the upper end of the pole so as to stabilize the upper end of the pole to prevent it from falling from side to side.
