DEFINITION

Classification: 15/250.27

(under subclass 250.001) Cleaning attachments comprising two or more surface contacting members mounted on the free ends of separate arms, the other ends of the arms being pivotally mounted on individual spaced axes to permit the free ends to swing back and forth across the areas to be cleaned, and means common to all the arms for simultaneously swinging the arms.

(1) Note. The means for swinging the arms back and forth must be more than a mere mounting which permits the movement and must include linkage, gearing, motor or other common drive means.
