Abstract
Abstract The structure of the present invention comprises an index file in the form of a shiftable table longitudinally operable upon a support base. The table is shiftable upon antifriction means, and may be releasably locked in position. Means is provided for sectionalizing the index cards or data folders carried by the table to maximize accessibility and minimize operator fatigue.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
An index file comprising a support base, a table shiftably mounted on said base, index file support means carried by the table, base rail means carried by the base, complementary table rail means carried by the table, the base rail means and table rail means having identical cross-sectional shapes, antifriction ball means interposed between said base and table rail means, and a vertically extending brake lever depending from said support base and having a lower foot operative portion, said brake lever releasably locking the table in various positions of adjustment relative to the base.
Claim 2
Dependent Claim
94 words
An index file comprising a support base, a table shiftably mounted on said base, index file support means carried by the table, base rail means carried by the base, complementary table rail means carried by the table, the base rail means and table rail means having identical cross-sectional shapes, antifriction ball means interposed between said base and table rail means, and a vertically extending brake lever depending from said support base and having a lower foot operative portion, said brake lever releasably locking the table in various positions of adjustment relative to the base.
Claim 3
Dependent Claim
24 words
An index file as set forth in claim 1, whereby said base and table rail means are interlocked together by said antifriction ball means.
Claim 4
Dependent Claim
32 words
An index file as set forth in claim 1, wherein said base and table rail means comprises a plurality of pairs of complementary rail members laterally separable to various positions of adjustment.
Claim 5
Dependent Claim
25 words
An index file as set forth in claim 1, wherein divider means is provided for sectionalizing the index file support means carried by the table.
Claim 6
Dependent Claim
32 words
An index file as set forth in claim 4, wherein said divider means comprises a channel longitudinally disposed on the top of the table, and shiftable divider members carried by the channel.
Claim 7
Dependent Claim
40 words
An index file as set forth in claim 5, wherein said divider members have a first position wherein said members may be shifted longitudinally of the channel, and a second position wherein said members are releasably locked to the channel.
Claim 8
Dependent Claim
93 words
An index file comprising a support base, rail means of a predetermined cross-sectional shape affixed to the support base, a table, rail means affixed to the table having a cross-sectional shape identical with the base rail cross-sectional shape and including a relatively depressed elongated outer channel formation, antifriction ball means interposed between said base rail and table rail, a vertically depending foot operated brake lever and brake pad means affixed to the brake lever for engaging the table rail depressed channel formation to releasably lock the table in various positions of lateral adjustment.
Claim 9
Dependent Claim
93 words
