Abstract
Abstract A plastic storage drawer or tray for data cards of documents provided with a positionable compressor or follower made of molded plastic elements. The drawer or tray supports a longitudinal guide track or channel, the compressor having integral track-engaging flanges and a releasable locking shoe for holding the compressor in adjusted position against the cards. The plastic compressor assembly encloses a pivoted locking lever carrying the locking shoe, and a spring normally urging the shoe against the longitudinal guide track. The locking shoe is shaped to permit the compressor or follower to be positioned without restraint toward the stack of cards in the tray. The guide track may comprise a metallic strip attached to one side wall of the drawer or tray. The bottom of the drawer is provided with reentrant shaped feet which cooperate with raised ledges on the top of the drawer to permit a series of drawers to be securely stacked one on the other vertically.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
226 words
In a molded plastic file drawer having bottom and side walls for filing data carrying media, the combination comprising: an elongate guide track member secured to the inner side of one of said walls between the top and bottom thereof and extending lengthwise of said drawer, and a compressor member slidably mounted on said guide track member; said guide track member being so shaped in cross-section as to form a pair of spaced longitudinally extending tracks and a channel between said tracks; said compressor member comprising: a flat wall portion extending substantially across the width of said file drawer to compress the media therein when the compressor member is adjusted toward one end of the drawer, a locking assembly for releasably retaining said compressor member in a fixed position along said guide track member to enable re-positioning the compressor member in the drawer, said locking assembly comprising first means extending into said channel adapted to yieldingly and frictionally engage said guide track member and second means for releasably retaining said first means in engagement with said guide track member, and a slide plate extending normal to the flat wall portion of the compressor member and having means slidably mounted to said spaced tracks for maintaining said wall portion in position as the compressor member is adjusted in the drawer by movement along said guide track member.

Claim 4
Dependent Claim
35 words
The file drawer and compressor member according to claim 2, in which said second means comprises a spring normally biasing said pivoted lever so as to press said shoe outwardly against said guide track member.
Claim 5
Dependent Claim
31 words
A file drawer and compressor member according to claim 1, in which said compressor member including said flat wall portion and slide plate comprises molded plastic elements enclosing said locking assembly.
Claim 6
Dependent Claim
34 words
