Abstract

An improved shoe for a casement window hinge is disclosed. The hinge has a base with a front end and a rear end and two sides. The base has a ridge on the rear end for securing the base to a track and a tongue extending from one of the sides. The tongue has a plurality of teeth extending from a side of the tongue. A gear wheel is adapted to be rotatably secured to a track. The gear wheel has a plurality of teeth about its circumference which mesh with the teeth on the gear wheel. The rotation of the gear wheel causes the base of the hinge to move longitudinally in relation to the track.
