[Class 146 (i)] In a filing-tray for vertical filing systems, and which is provided with a follower plate at one or both ends of the tray movable into an inclined position in which the upper part is outside the open end of the tray, the follower plate is so connected to the inside of a structure slidably carried by the tray that it is capable of both pivotal and rectilinear movement on the structure, and the latter is capable of being projected beyond the open end of the tray, means being provided to restrain the lower end of the follower plate, so that, when the structure is projected, the plate takes up a position in which its lower end lies within the tray and its upper end is supported by the structure outside the end of the tray. The open-ended tray comprises sides 1, folded over at 1<1>, and a bottom 2 with strengthening grooves 2<111>, and grooves 2<1> in which flanged rails 3 are secured by rivets. Shoe-pieces 4 of L- shaped upright supports 6 for the follower plates slide in the rails 3, and one of each pair is provided with a projection 14, adapted to engage with any of a series of depressions in the rail 3 to position the follower plates. The uprights 6 are joined by plates 10 with bent-out handles 10<1>, and by cross-bars 7, which engage with elongated stirrups 8 on the follower plates 9. The plates 9 are held off the bottom of the drawer by projections 9<1> and are engaged by stops 11 in the projected position of the supports. Stops 12 engage shoulders on one of the shoes 40 prevent the complete withdrawal of the follower. One of each pair of shoes 4 is shorter than the other, and the short and long shoes of the two followers are arranged in the same rail. A longitudinal card-engaging rod may be mounted on uprights between the grooves 2<1>, and the bottom of the tray may be provided with longitudinal notched member to engage the lower edges of frames for visible indexes.
