Automatic surface-treating apparatus
First Claim
1. Automatic surface-treating apparatus of the type supported by and traversing a horizontal surface unattended, comprising:
- a frame;
mobility members on the frame rotatable about axes extending in a first horizontal direction;
means on the frame fo treating the surface as the apparatus traverses the surface;
side-step members on the frame rotatable about horizontal axes transverse to the first direction and a given distance above the surface, each side-step member having;
a first sector with a far periphery spaced from its axis by more than the given distance, anda second sector with a near periphery spaced from its axis by less than the given distance;
whereby rotation of the side-step members will lift and move the apparatus laterally a predetermined distance.

Abstract
Improved automatic surface-treating apparatus of the type supported by and traversing a horizontal surface unattended. The apparatus includes mobility members for movement in a principal direction and side-step members having rotational axes a given distance above the surface. Each side-step member has a first sector with a far periphery spaced from its axis by more than the given distance, and a second sector with a near periphery spaced from its axis by less than the given distance. This arrangement allows a single rotation of the side-step members to accurately lift and move the apparatus laterally through a predetermined distance, to a new surface-treatment path.
