The invention relates generally to filingcabinets and more particularlyto cabinets which are equipped with drawers of the typein which the front is pivoted so that it will drop to provide convenient access to one end ,of aV stach of sheets or papers `in the draw-' V'Iheobjects of the invention aretol provide: ka tiling cabinet drawer of this typeV in which the bottom, sides and back are in-r` tegrally formed of sheet inetal'and in which f the runners for supporting the drawer in the cabinet y are integrally formed with the drawerV sides; a drawer of this type in which the runners are formed at the upper margins of the drawer-sides; a'drawer ofthis type"` f in which the dropy front is provided with means-for holding'it closed and supporting until it has been withdrawn the desired eX- tent before releasing the front; a drawer of in which provision is made for stiffening the drawer-sides; a drawerof this type in which provision'is madefor preventing inwaii'd flexing of the front portions of the drawer sides" when the drop front is closed; and an-v improved i'iling cabinet for drawers of said GI'S.
type yin which grooves areV formed 'in sheet metal plates Vfor the runners on the draw- The'invention consistsin the lseveral novel features hereinafter set forth and more particularly A,defined .sion hereof. Y In the drawing Fig. 1 is a-plan of a filing cabinet drawer' embodying theinvention.
Fig. "2 is a ,side elevation. "Fig: 3 is a longitudinal section of ra cabinet, showing the ini-` proved drawer mounted therein. Fig; 4 is fra lsection on line 4-4 of Fig. 1 upon an enlarged scale. I F ig; 5 is a vsection on liiie'v' offFig.-1 on anenlarged scale. Fig. 6 is a ysection on line 6-6 of Fig. 2. Fig. 7 is a section on line 77,-7'of Fig. l
The invention .is exemplified in al drawer comprising a bottom 6, back 7: and sides l i v8, all of whichV are formedof, a ysingle blank of -slieetinetah suitably 'cut and bent, lapped joints being formed between bythe claiiii at the conclu-'` the back 4and sides, l'so the back Aof the drawer will be,` substantially rigid. A front 9 is secured to'braclrets l0 which are pivoted by pivots vv11 adjacent the lower inargin ofthe outerfaces of the drawer sides S, to periiiit'the front'to be lowered or dropped "f into position indicated `by dotted llines in y when the drawer is withdrawn lfrom Fin. 3
theliciibinet. Pivots 11 pass through the drawer sides and-lugs 12 which are secured y to thei drawer sides `by rivets 13. In dropn g vfront Y drawers which are formed of sheet metal, the sides are not rigidly cross con- `nected at the front and, consequently, there is considerable flexibility to them. This ileX- ibilityresults, not konly from the circumstancethat the sides are lateralaround their lower corners, but also thewerticall leixibility of the/bottom. To reduce undesirable flex ibility,l the bottoin 6 is formed with 7 transverse corrugations 14 which terminate o vsubstantially atthe corners betweenlthesides and the bottoin `and by stiifening the bottom,
r"thesecorrugations serve to lessen the transverse yflexibility of the sides. The corrugay tions are formed by indenting the sheet metal bottoindownwardly and it is' important that th ey extend `r,transversely of-the bottoniA in order to perform their desired function. In order to secure the front portions of the sides .l
- against inward movement, more particularly Ato prevent them4 yfrom warping inwardly while' they are iii the cabinet, tongues l5,
which may be struck upfiointhe inetal forining brackets 10, aiepi'ovidedto' i'eceivefthe Ifrontedges of the drawer sides 8, so that the wall 19, extending longitudinally of the draw# 1 er. These runners are adapted to slide in grooves 2O in'a cabinet 21 which may be adapted to hold any desired number of drawers. The grooves 2O are formed in sheet metal inyner side walls 22which are suitably secured in outer metal Walls 23. A characteristic of this cabinet is that thek walls22 are bent to form the grooves 20. i
To cause the drop front to be supported by the bottoms of grooves 20, thebrackets l0 are formed with an out-turned flange 24,
which, when thedrawer is pulled out away from the cabinet, will be released to permit the front to swing downwardly to give access to the papers in the drawer.V The lower wall 19 terminates adjacent therearo-iiange 24 and the top wall 17 of each runner is extended, v
as at 25, over the iange 24.
The invention exemplifies a filing cabinet"Y i il in which a drawer with a drop front is formedA y of sheet metal with runners integrally formed y thereon in which provision is made for avoid- Y ing undesirable'flexibility of the, sides; in I. f Ywhich the sides are locked at their front'ends f against inward movement, while the. drop front is closed, and in which the runners are formed at thefupperimargins of the drawers,
Y and in which the brackets of the drop lfront are provided with means Yheld in the'cabinetf to keep the drop front closed',iand in whichthe tiling cabinet is provided with grooved sheet metal'walls for the runners on the drawv y l fmay bemodified within the scopeof theap-l pended claim, without departing from the l The invention is not to be understood as I i restricted to the details set forth, since these spirit and scope of the invention. Y f
Y Having thus described the inventiom what p `I claim as new and desire to secure by/'Letters Patent, is: 1 f
' A liling cabinet drawer comprising -abottom-,back and sides,runners projecting outi A wardly from the upper -marginsof-said sides and adapted to slide in groovesin the cabinet, f
- said `runners comprising' upperv and' lowerA walls, the front endsjof'the upper'walls eX- tending 'beyond the lower walls, a dropV front pivoted tothe sides, and flanges on theffront adapted'to underlie said extendedl front vends of t-he upper walls and form continuations of the lower walls to supportz the drop front,
when the Vdrawer is in the cabinet.y c
