PANY, F MUSKEGON, MICHIGAN, A CORPORATION lOF MICHIGAN METAL DESK CONSTRUCTION Application filed March 2,

This invention relates to improvements in metallic desk construction, and more particularly to an improved mounting for the drawers of .such desks, whereby smooth and easy sliding movement ofthe drawers'may be maintained, and periodic lubrication may `be resorted yto without danger of soiling the person or clothing by contact with the drawer whenopen. l

The object of theinvention is to provide a type of track member which will permit of lubricating the tracks and yet protect and conceal them in such manner as to prevent the lubricated surfaces from being` exposed when 16 the drawer is opened.

The features embodying the invention are not necessarily limited to metal drawers or to metallic furniture, although particularly suited thereto. f f

Referring to the accompanying drawing: r

Figure 1 is a view in side elevation of one of the drawers of a desk with portions of the track members broken away. l

Figure 2 isa view'in cross section through the drawer and supporting walls as taken on line 2 2 of Figure l.

Figure 3 is an enlarged view in elevation of a section of a .stationary track member.

Figure 4 is a ,View in cross section through the stationary track member as taken on line 4-4 of Figure 3.

Figure `5 lis a view in side elevation of the sliding track member n the drawer, and

Figure v6 is a cross-sectional view of the track member taken on line 6-6 of Figure 5.

Asis the common practice in desk construction, a drawer 1 is mounted within a drawer compartment represented by

vertical side walls

2, 2, as for instance of a pedestal.v In ythis disclosure both the drawer and the

walls

2, 2 are of sheet metal, the former comprising an open receptacle with vertical side walls la, la and a front wall 16, having a suitable handle or vpull 1c. for endwise sliding movement to and from closed position in the desk on pairs

vof track members

3 and 4 on opposite sides, one member 3 of each pair being stationary and ixed to the walls 2, and the other 4 being mounted 59 on and sliding with the drawer.

The drawer is mounted iaai. serial No. Maase.

sheet metal stamped or pressed to the crosssectional shape shown in Figure 4, namely, a

vertical web 3a which bears atwise against the side wall 2, and preferably spot-welded thereto as atl/w, a, narrow web 3b along the upper edge of the vertical web and bent inwardly at right angles theretoy and an inverted U-shaped rail 3c along the edge of the narrow web 3b. Near the forward end of each fixed track member an elongated hump 3d is pressed upwardly from the rail portion 3c and forms the contact surface for the track 4member on-the drawer as shown in Figure, 3. The track members 4 on the drawer are likewise formed from strips of sheet metal stamped into the sectional contour r shape shown in Figure 6, namely, each consisting of a vertical web 4a which is spot-welded to the side wall 1a of the drawer as at lw, a web 4b bent. at right angles along the lower edge of the vertical web and a short downwardly depending flange 4c along the outer edge of the web 4b. Near the rear end of these track elo in Figure 1, that is, the hump 3d at the forward end of the stationary track member 3 supporting the track member 4 on the drawer while the hump 4d at the rear end of the drawer track member 4 bears upon fixed track member. And finally the depending {iange 4c of the drawer track member extends outwalrdly beyond and downwardly along the side of the invert U-shaped rail of the fixed track member, so that when thedrawers are withdrawn, the track surfaces which may have a film of oil thereon are completely covered and thus protect the hands or clothing from heini soiled by contact with the lubricated trac surfaces or other surfaces that "2 I f y 1,873,933

might be coated with lubricant spreading from the track surfaces, when the drawers are pulled out into open position. Ordinarily a few drops ofvoil applied to the track sur- 5 faces are suicient lubrication for a long period, but should-they be oiled ,too frequently there would be the possibility ofl anv excess forming on surfaces whichleft exposed would create an uncleanly condition. I

Having set forth a preferredl embodiment of' my invention, I claim:

1. In a drawer construction for fdesks,the combination with a ydrawer compartment of pairs of horizontal track members for slidably supporting a drawer, each pair consisting of a xed track member on a vertical wall of said compartment and a movable track member on the side of said drawer,`and having overlapping transverse track iian'gesy 2Q spacedapart vertically by the provision of A fe-le'vatedportions at opposite ends of said.

I track flanges, one of each ,pair of track members having an outwardly disposed depend- 1., ing web enclosing said track surfaces.` 2. In a drawer ,construction for metal desks,the combination with a drawer comartment of `pairs of horizontal track memers for slida ly supporting a drawerv thereon, each pair consisting of a fixed track mem- -ber having a vertical web adapted to fasten flatwise against the vertical wall of said compartment and an inverted U-shaped rail projecting toward said drawer, a movable track member fixed to the side of said drawer and 'having a transverse track iange overlying and having sliding contact with said rail, and

a depending w'eb along its outermost edge exf tending over and concealing the rail of said xed track member. 'l

4 3. In a v drawer construction forl metal desks, the combination witha drawer compartment of pairs of horizontal sheet metal track members for `slidably supporting said drawer, each pair consisting of a fixed track member having avertical web adapted to be welded to the vertical wall of )said compartment, an inverted U-shaped rail projecting inwardly along its upper edge provided with a raised hump in the upwardly facin track surface near one end thereof, a movab e track member on the side of said drawer having a y vertical web welded to the drawer, a transverse flange overlying said rail and ha' ing a depressed hump adjacent the opposite end .of said track `flange, and a web along its outer edge extending downwardly'beyond' the rail of said fixed track member whereby said tracks slide on said humps at oppositely disposed ends and said track surfaces are concealed by said depending web of said mov- ,able track member.
