o o j zolaims. (o1. 12sisi` This invention'relates toiling trays for ledger cardspvisible index panels andthe like having tilting end walls, and particularly to the endlwall structure and the means for` holding the end wall in upright and inclined positions. o

The invention comprehendspthe provisionv of a filing tray with a tilting end wall having a re taining member slidable` on the ,end Wall, provided with a lateral projection, the projection and tray being formed with `shoulders arranged to cooperate to support the end wall in both upright and inclined positions, :'the retaining member being normally operated to rhold. the `shoulders in engaged relation 4while a suitable handle is provided to operate the retaining memv ber to disengage the shoulders so the end wall may be moved from one position to the other.A

The invention further comprehends the j orovi-r sion .of 'a filing `tray having a ,hinged end wall constructed of a pair of spaced sheet metal sections slidably` mounting a retaining strip between the sections lformed with a lateral projection provided with shoulders to engage ashoulder on the tray, and normally heldin one position to cause said shoulders to engage and retain the end Wall in either upright `or inclined position, while a handle member is provided for operating the retainer strip to disengage the shoulders through manual operation of the handle in order to pro` vide'for movement of the' end wall from one positionto the other. v

The invention providesan end wall structure madeof sheet metal hinged to the end of a tray having inner and outer sections secured together f vtion so the shoulders may be disengaged to pro- Vide for movement-fof the end Wall from the upright to the inclined position. l o

The inventionalso comprehends several specific -features involved inthe construction of the end wall and theassernbly of the retainer mein-` ber therein, to provide an end wallv structure that is simple in construction and assembly as herefA inafter pointed out indetail in the specication and claims. o v.

Shouldersj are supported in the space between the return bends 4 and sidewalls 3 at the ends of tion so that a description of one will suffice for both/1.` i

lilaohv end'wall is constructed with an outer sheet metal section@ andan inner sheet metal .section Hi. Section 9 is provided at theplower end with a plurality of hinge knuckles H that intert between hinge knuckles l' to receive a hinge pintle forlhingedly mounting end wall 8 on the tray.' `At the upper end outer section 9 is formed to provide a cylindrical portion l2 reinforced by `:40

`rod I3, the centralportion of the sheet metal be-V torn, and i8 at the top, that are spot welded or otherwisejrigidiy secured tothe ,inner face of onteni extension 20 located under cylindrical portion I2 in the manner illustrated in Fig. 1

The side edges of inner' section I II are provided with lateral flanges 2| slidably intertting inside of side flanges I5 on outer section 9 and channel members 22 extend between lateral flanges I6 of inner section I0, one being located along each side of inner sectionv Il! adjacent to flanges 2'I. These channel members are suitably spot welded or otherwise rigidly Vsecured to inner section IIl and have approximately the lower one third portion of the length of the edges cut away as indicated at 23 to provide guideways between` the channels and the inner lface of outer section` 9 for receiving a retaining member 24.

Retaining member 24 is `formed from a strip of sheet metal having lateral end projections 25 extending through slots formedv at the side edges of end wall 8 between the sides of inner section III and flanges I5 of outer section 9. These end projections 25 extend along the inside faces of side walls 3 of the tray under return bend portionsl 4. The upper edges of projections 25 are formed with a pair of projections 2B and 21, respectively, providing shoulders on each projection for cooperating with shoulders 5 on the tray side wall for supporting and retaining end wall 8 in either vertical or inclined positions on the tray. Projections 26 cooperate to retain end. wall 8 in vertical position and projections 21 retain the end wall in inclined position. Projections 21 are longer than'projections 26 and have angular end portions 28 adapted to engage over angle portions 29 of the l'shoulders 5 for holdingretaining member 24 in engaged relation with shoulders 5 and normally preventing said retaining member from being manually operated to disengage shoulders 21 from shoulders 5.

The upper edge of projections 26 is formed to provide cam portions 30 adapted to engage the under faces of projections 5, so that when end wall 8 is manually operated to move it from the,

inclined position to the upright position, cam portions 30 on projections 2S will move retaining member 24downwardly in order to automatically position retaining member 24 so the shoulders on projections 26 may engage with shoulders 5 and latch end wall 8 in upright position.

Retaining member 24 is formed with a lateral flange 3I on the lower edge Awhich seats on spring 32 supported on lateral flange I6 at the lower end of inner section I0, operating retaining member 24 to normally hold projections 26 and 21 in position to engage shoulders 5. Astrip 33 mounted in the central portion of retaining member 24 extends laterally thereto and upwardly between outer and inner sections 9 and I Il. The upper end of strip 33 is doubled upon itself as indicated at 34 to provide a handle extending through a slot in the central portion of 4flange I6 at the upper end of inner section I0. Handle 34 projects into hand opening I4 in the manner illustrated in Fig. 3 so as to be readily engageable for manual operation to depress the handle for moving retaining member 24 downwardly to disengage shoulders 26 from shoulders 5 and thereby provide for movement of end wall 8 from the upright to the inclined position.

This construction provides a very simple tilting end wall structure for filing vtrays including a retainer member slidable vin the endwall and arranged to engage the sidewalls ofthe tray to form extensions thereof when the end wall ris moved into the inclined position beyond the end of the tray, and at the same time, provide a means for supporting the end wall in both upright and inclined positions. This construction reduces the number of parts to a minimum so as to obtain an economical and yet eiicient structure. While the inner and outer sections 3 and I0 are welded together as above described thereby providing a permanent assembly of the parts, it will be understood that they may be detachably secured together,v if desired, so that access can be had to the retaining member and spring 32 for replacement thereof if desired.

The invention claimed is:

1.' A iiling tray, comprising a body having bottom and side walls, an end wall for movement between upright and tilted positions having an outer sheet metal section hinged at the bottom to said body, an inner sheet metal section having lateral end flanges terminating in offset end extensions secured to the inner face of said outer section and mounting said inner section in spaced parallel relation, a channel strip at each side of said inner section having the center portion thereof secured to the side margin of said inner section,` said channel strips extending to the ends of said inner section and having the edges engaging the inner' face of said outer section, said channel strips having a portion of the edges removed to' provide a gui-deway between said strips and outer section, a retainer strip extending across said end wall slidable in said guideway, said retainer strip having laterally projecting ends at the side edges of said end wall overlapping said side walls in contiguous parallel relation and spaced above said bottom wall, cooperating shoulders formed on said laterally projecting ends and said side walls for supporting said end wall in upright and inclined positions, a lateral flange formed on said retainer strip, a spring between said last-named ange and a latveral end flange on said inner section normally operative to slide said retainer strip in one direction for retaining said shoulders in engagement and a handle formed of a strip of sheet metal having one end secured to said retainer strip and the opposite end projecting laterally therefrom between said wall sections to the upper ends thereof for manual engagement for moving said retainer strip in the opposite direction to disengage said shoulders, said laterally projecting ends forming side wall extensions for said tray to close the opening between said end wall and the ends of said side walls` in the tilted position of said end wall,

2. A filing tray comprising a body having a bottom and side walls extending upwardly therefrom, an end wall for movement between upright and tilted positions at one end of said tray, said end .wall having inner and outer spaced wall sections,`said sections having laterally eX- tending edge anges connecting said sections in assembled relation, a hinge at the bottom of one section connecting it to the end of said tray bottom, a retainer strip having the central portion extending between said wall sections and slidable in said end wall above said bottom, and havin g laterally extending end projections formed with shoulders to engage shoulders mounted on the side walls of said tray and operable to support said end wall in'upright and tilted positions, resilient means engaging between the bottom edge ilange on said wall sections and the bottom edge of the central portion of said retainer strip for normally retaining said shoulders in engagement, and a strip attached at one end to the central portion of said retanerstrip, projecting laterally therefrom andvextending outwardly through a slot'in the edge flange at the upper part of said end Wall and forming a handle l for manual engagement to slide said retainer f strip downwardly in said end Wall against the Wall extensions beyond the ends of said side Walls for closing the end of said tray when said end wall is in tilted position.
