In this drawing is ers of the type to which this invention relates, in their standard construction comprise, in addi tion to front, side, and end walls, a bottom wall; 10 illustrated a ?le drawer In of a standard con‘ and it is upon this bottom wall that the follow struction,. ‘except as hereinafter noted. This ers which I am familiar bear with excessive force drawer l0 includes side walls II and front and in orderlto clampingly ?x the follower in card back walls l2 and I3, respectively, the back wall supporting position. Such followers bear‘ upon l3 having the usual hand opening M formed the side walls as well asthe bottom wall. In 15 therein. This drawer further includes a bottom such cases, by actual experience I have found wall I5. In this drawer is adapted to be mount that due to the excessive pressure exerted upon ed ?le matter |6 which may take various forms the clamping parts of the follower in order to but which is shown, in the present instance, as in hold the follower in place, the side walls some the form of cards. These cards are retained in times buckle and invariably where the bottom 20 a stacked position within the drawer ID by the wall is made of a relatively thin, single, dr veneer follower IT. This follower |'| comprises a cap portion I8 and a base portion Hi. The cap por strip or sheet of wood, it, being weaker than the side walls, will buckle outwardly. This buckling tion l8 comprises a card-engaging wall 20. Se cured to one face of this wall 20 is a pressure of the side and/or bottom walls‘results in a dis turbed mounting of the cards or other ?le mat 25 block 2| having a portion cut therefrom to pro ter in the drawer.

As a consequence, the life grooves 25 formed in the opposed faces 26 of the of the ?le drawer is greatly shortened and the ‘ ‘ 7 drawer itself rendered inefficient for its purpose. 30 side walls I I.

This erence to the accompanying drawing showing projection 35 engages in the recess 22. The base the preferred form of construction, and in which: Fig. 1 is a perspective view of a ?le drawer 45 block 36 is slidably connected to the card-engag ing wall 2|] by means of a lateral projection 31 showing my improved follower associated there which engages in a recess 38, the recess 38 being with; wider than the thickness of the projection 31, Fig. 2 is a fragmentary sectional detail view of the ?le drawer showing an end view of the fol 50 whereby the block 36 may have the proper down ward movement relative to the wall 20. This ar lower embodying my invention; rangement unites the follower into a complete Fig. 3 is a fragmentary cross sectional detail unitary structure whereby the same may be ex view of the ?le drawer showing my follower as peditiously mounted and removed from its po sociated therewith; Fig. 4 is a fragmentary sectional detail View of 55 sition in the file drawer. The opposite end portions of the base block 2,407,055 3 36 have laterally extending lugs 39 which en grooves and adapted to bear on adjacent walls of gage in grooves 40 formed in the opposed faces said grooves when moved in said opposite ver of the side walls II. a position with the base block 36 slightly spaced tical directions, and means for moving said sec tions in said opposite vertical directions. 3. In combination, a drawer comprising side walls having parallel grooves formed in each of as at 4| above the top surface of the bottom IS, the opposed faces of such walls, a follower mount The grooves 25 and 40 are so spaced with re spect to each other as to support the follower in ed in said drawer and comprising sections the arrangement being such that when the lever adapted to have vertical movement in opposite 29 is manipulated to bear the cap l8 and base block 36 away from each other, no part of the 10 directions with respect to each other and having horizontal slidable connection with respect to follower will engage the bottom wall.

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 adapted to have vertical movement in opposite 40 projections slidably engageable in said grooves, and camming means carried by one of said sec directions with respect to each other and includ tions and adapted to engage the other of said ing lateral projections engaging said grooves and sections to bear said projections against ad adapted to bear on adjacent walls of said grooves jacent walls of said grooves to clamp said fol when moved in said opposite vertical directions, and means for moving said sections in said op posite vertical directions. 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.
