Abstract
A suction nozzle is provided with a linearly movable, stepped cam which adjusts the height of the suction nozzle by acting against a pivoted wheel carriage. The stepped cam is relatively fixedly positioned by an indexing means including a deflectable arm which is manually deformed to release the fixed indexing and then manipulated in a sideward direction to move the position of the stepped linear cam means.
