ABSTRACT:
The side faces of a reciprocable drawer carry U-shaped rails whose flanges are outwardly adjacent to the flanges of complementary U-shaped rails which are adjustably secured to a stationary member of the piece of furniture in which the drawer is installed. The front ends of the rails are accessible when the drawer is moved to a partly or fully open position, and the front ends of the rails on the stationary member can be moved up or down by eccentric worm wheels which are mounted between the flanges of the complementary rails and engage the respective upper flanges. The worm wheels can be rotated by worms which are mounted in the complementary rails and mesh with the respective worm wheels. When a worm is rotated, the corresponding eccentrically mounted worm wheel effects an upward or downward movement of the front end of the corresponding complementary rail, and such rail causes the front end of the associated rail on the drawer to share its movement. The worm wheels are secured to the stationary member by screws whose shanks extend through elongated vertical slots of the corresponding complementary rails. Cages with rolling elements are interposed between the flanges of the rails on the drawer and the neighboring flanges of the rails on the stationary member.
