ABSTRACT:
A device for stringing tennis rackets and the like, and for tightening sagging strings, which, in the preferred embodiment comprises three rows of rollers clamped around two adjacent strings inside the racket frame. Each row of rollers is attached to the end of a lever. The levers are rockingly linked together so that the strings can be gripped and released between the rollers as desired. The rollers are mechanically coupled to each other by way of a series of intermeshing spur gears. A crank, attached to the gears, drives the rollers and allows adjacent rollers to rotate in opposite directions. Thus, two strings in gripping engagement with the three rows of rollers are pulled in opposite directions as the crank is turned.
