While I have illustrated and described the pre

recess being larger than the thickness of said rib

to permit freedom of movement of said rib

scope of the appended claims.
Having thus described my invention, what I
claim as new and desire to protect by Letters Pat
ent is:
1. In combination, a drawer comprising side
walls having parallel grooves formed in each of
the opposed ~faces of such walls, a follower
mounted in said drawer and comprising sections
a predetermined distance relative to said cap por
tion.
5. A follower for a ?le drawer, which drawer
comprises sidewalls, front and end walls, and a
bottom wall, with each of the sidewalls provided
with spaced parallel longitudinally extending
grooves on its inner face thereof, comprising sec
tions adapted to have vertical movement with re
spect to each other and provided with lateral

and camming means carried by one of said sec

and means for moving said sections in said op

2. In combination, a drawer comprising side
walls having parallel grooves formed in each of
the oposed faces of such walls, a follower mounted
in said drawer and comprising sections adapted
to have vertical movement in opposite directions
with respect to each other and having horizontal
slidable connection with respect to each other
and including lateral projections engaging said
- lower in a position with said drawer, said fol
lower being supported by said projections and
said side walls with its lower edge portion slightly
spaced above the bottom Wall of said drawer to
avoid pressure being applied on said bottom wall
* when said camming means is manipulated to bear
said projections against said adjacent walls of
said grooves.
