Nov. 10, 1953 W. H. BOWDEN DRAINBOARD File d Oct. 5, 1949 INVENTOR. MLL/AM f7. BOWDEN Patented Nov. 10, 1953 DRAINBOARD William H. Bowden,

This invention relates to an improved porcelain-coated drainboard for use in a porcelaincoated sink provided with a plurality of sumps, the drainboard being slidable from a position over one of the sumps to a position over another sump. The drainboard slides on gliders which project from its sides and ends and serve as bumpers which prevent the edges of the drainboard from contacting the sink.
The drainboard and sink are both formed of enameled sheet metal. If the drainboard were permitted to bang the sink repeatedly, in being shifted from a position at one end of the sink to a position at the other end, the enamel on one or the other or both would eventually chip. By locating the bumper-gliders at the corners of the drainboard and positioning them so that they project from the ends as well as the sides of the drainboard, this is prevented.
The bumper-gliders are made of a resin-like plastic which is softer than the porcelain, such as Lucite (methacrylate resin), Micarta (phenolformaldehyde resin), etc. Other natural or synthetic resins may be used which are hard enough to resist abrasion and slide easily over the surface of the sink without marking it, but not hard enough to damage it. Alternatively, resin-impregnated fabric, etc. may be used. The gliders are designed to last for the life of the sink but may be easily replaced if they become excessively worn.
The invention will be further described in connection with the drawing, in which- Fig. 1 is a plan view of a sink and drainboard;
Fig. 2 is a view on the line 22 of Fig. 1, with a portion shown in section;
Fig. 3 is an enlarged fragmentary section of the sink taken on the line 33 of Fig. 1;
Fig. 4 is an enlarged plan View of the upper left-hand corner of the drainboard and the adjacent, portion of the sink; and
Fig. 5 is a sectional View through a corner of the drainboard taken on the line 5-5 of Fig. 4.
The preferred sink is provided with two sumps I and 2. Around the rim of each sump is a ledge 3 and rising from the outer edge of this ledge is a substantially vertical wall 4. As best shown in Fig. 3, the wall 4 is joined to the ledge 3 by a radius portion 5. The flange 6 extends outwardly from thi wall along the front and at both ends of the sink. Along the back of the sink where wall :3 is somewhat lower than alon the front and the two sides, there is a flat tray 1 the surface of which is just below the surface of flange 6. Suitable holes 9 are provided through this tray portion to receive plumbing fixtures and the like. Sump I is provided with a suitable drain hole I I and sump 2 is provided with an opening I2 for attachment to a garbage disposal unit.
The drainboard I5 which is of sufficient size to cover either sump is formed with grooves I! which provide drainage. It fits just inside the wall 4 which extends around the sumps. The edges of the drainboard are bent downwardly to form flanges I 9 along the four sides of the board, except that at each corner a portion of the drainboard is bent downwardly at about thirty-five degrees to form the attaching flanges 20. Excess metal is cut away from each edge of each flange 2i] and the nearest edge of the adjoining flange I9.
Bumper-gliders 23 which support the drainboard are attached to the underside of the flanges 29. They are molded with a bushing 26 through the center, and each is fastened to its flange 20 by a screw 2'! which passes through the flange and is threaded into a hole in the bushing. The angle of the corner 28 is the same as the angle between the flange 20 and the top of the drainboard. The glider fits snugly into this angle and is thereby held rigidly and prevented from turning.
Although the gliders 23 may be any shape, they are shown as being generally rectangular. One glider is fastened at each corner of the drainboard so that one edge 29 projects outwardly from one side 30 of the drainboard and the other edge 32 projects outwardly from the adjoining end 33 of the drainboard. All projecting edges are rounded. As the drainboard is slid along the ledges, the edge 29 of each glider slides in the radius 5 at the base of the front and rear walls 4 and this centers the drainboard laterally over the sumps. The gliders space the sides 30 of the drainboard from the front and back portions of the wall 4, and when the drainboard is slid against either end of the sink the edges 32 of the gliders at that end of the drainboard keep the drainboard from striking the wall 4 at that end of the sink. Thus the gliders, projecting beyond the four edges of the drainboard, serve as bumpers which prevent any portion of the drainboard from coming into contact with wall 4 which surrounds the sumps.
Preferably, the ledge of the sink will be continuou from one end of the sink to the other and will be suitably inclined toward the sumps to facilitate drainage. The drainboard may be used with a sink provided with any number of sumps in line with one another so long as there is a surface along the front and back rims of the sumps for the gliders to slide along. Ordinarily a sink will have only two sumps. The gliders 23 may be of any shape so long as they also serve as bumpers.
What I claim is:
1. A rectangular porcelain-coated sheet-metal drainboard adapted to be slidably mounted on a sink, having at each corner a bumper-glider on which it is adapted to slide, one corner of the bumper-glider extending beyond the adjacent side of the drainboard and another corner of the bumper-glider extending beyond the adjacent end of the drainboard.
2. A rectangular porcelain-coated sheet-metal drainboard adapted to be slidablyv mounted on a porcelain-coated sink, at each corner of the drainboard and attached to its under surface a bumper-glider of resin softer than the. porcelain, one edge of each bumper-glider extending beyond the adjacent end of the drainboard and another edge extending beyond the adjacent side of the drainboard.
3. A rectangular porcelain-coated sheet-metal drainboard adapted to be slidably mounted on a sink, the metal at each corner being bent down at an angle less than ninety degrees and having fastened to its under surface a bumper-glider opposite out-side corners of which extend beyond the side and end of the drainboard to which it is fastened.
4. A rectangular porcelain-coated sheet-metal drainboard adapted to be slidably mounted on a porcelain-coated sink, the metal at each corner being cut away a very short distance and the remainder bent down at an angle less than ninety degrees and havin fastened to its under surface a bumper-glider which is of resin which is softer than the porcelain of the sink but hard enough so that it will not mark said porcelain when slid over it, one edge of each bumper-glider extending beyond the adjacent end of the drainboard and another edge extending beyond the adjacent side of the drainboard.
