Application filed December 1c, 1926. Serial no; 153,820.

My invention consists of an improvement in drain boards fors nks and 51111118.! conv structions. It has in view to provide a sheet metal board of. stro light construction, having a slightly inclined bottom, a rear upwardly extending splash board portion, and a relatively shallower front and end .walls provided with rounded rims.

The boardis particularly designed for attachment to and connection with a sheet, -metal sink construction forming the sub ect matter of a companion application filed herewith, Serial No. 153,819.

To such end, the board is formed of a mainsheet metal blank having an upwardly bent splash board portion, a bottom portion at ,right angles thereto, and an upwardly bent front of less depth with a rounded edge-- portion,-in one integral piece. Also, an upwardly extending end portion is weldedto and merged into such portions, and varifi s other featuresof construction and advantage, as more fully hereinafter described.

- In the dra 7 showing one preferred embodiment of t fiehnventiona Fig. 1 is a perspective view of my improved splash board, as applied to a sink;

Fig.12 is a .view of the same in front elepvation;'

Fig. 3 is a longitudinal section o'nthe line ,III-AIII of Fig. 1;

Fig. 4 is a cross section on the'line IV- IV of Fig. 1;

Fig. 5 is a partial longitudinal section similar to Fig. 3, showi a modifiedconstruction of scouring-1e ge, used 'with a 7 double unit sink.

ly at the top by a square top flat section 7,.

and then downwardly parallel with the .front sheet ofr'ear wall 2, and is provided with similar end flanges 8, for finish at the outer end' andconnection at the inner end, respectively, as. hereinafter described.

Such back portion to any sufiicient height, and is preferably of the'same height as that of the splash wall 6 of a sink, as like that of the companion application above noted.

The front wall 4: extends upwardly, integral with the bottom 3, and is rounded outwardly, as at 9, providing afinishing 'rim. Bottom 3 slopes upwardly, more or less, sufficient to provide drainage into the sink cavity and rim-9 preferably slopes to a slightly greater degree in the'same direction,'as shown in Fig. 2. The end portion of the drain board is closed by an end wall 10 extending inwardly between the end of the front wall 4 and the inner end portion of the splash wall 2. Said end is of a separate piece of sheet metal, having an upper rim 11 matching into the corner'of rim 9 by a miter joint 12.

The lower edge of the end wall is rounded,

"as at 13, into the plane of the bottom 3, and

is electrically welded thereto on the line a,

thus providing a flush continuous surface on the inside. The inner end of the end wall is likewise welded to the lower end portion of the splash wall 2, as at 14, the end wall being preferably cut out for interfitting connection therewith.

By such construction, it will be seen that the end wall formsa practically continuous extension of the bottom interruption, and is, in e ect, integral therelate, with out any with, due to its welded connection and any supplemental smoothing or finishing to remove roughness or obstruction.

At its inner end, bottom 3 is turned down over-the inner edge portion of the adjacent rim 6 of the sink B, and is secured thereto by a plurality of screws orbolts 15 prefer- -a ly having'tightening nuts on the inner side. The splash board member 2 is simie larly connected to theend portion of the splash wall 6 of the sink by bolts 16 fixedly connecting and supporting the back wall of the sink and providing, in effect, a continuous extension of the main sink splash wall on the same general level therewith, .clear out to the end of the drain board. The

Y splash wall 6' of 'the sink is provided with an endmostweb or flange 24 and splash wall 2 is similarly provided with a web or fla 25.

' ill: joint 17 between the 'said't-wo elements is substantially tight under the tension of the bolts, preventing the entrance of any water, and the sheet metal of the back 2 of the drain boardis extended across the joint and outwardly a slight distance by means of the suitably shaped tongue extension 18, as 'in Fig. 1, immediately inthe rear of the downwardly turned terminal lip of the bottom 3.

' supporting leg or legs of the sink at its inner lower portion, and with the outer end of the drain board by flange and bolt connection, as at 21.. In this manner, the drain board is rigidly supported, in addition to its connection with the back wall of the sink,

so that it is, in effect, a relatively stable portion "of it.

-Where two or more sink units are associated, as in Fig. 5, the sinks B are preferably spaced more or less apart from each other, and are connected by a scouring ledge 22, which fits over and around the usual rims b and is secured by bolts or screws 16 in the same general manner as is the inner edge of the drain board, Fig. 1.

The scouring ledge thus provides a covering bridge between the adjacent sinks, and also extends upwardly by a back 23 to the same general height as the sink bracket 6 at each side,- being connected therewith by flange and bolt connections 16, as already described.

The scouring ledge and its back are atso provided with overlapping lips .18, similar to that of the drain board, and as thus connected and mounted, the securing ledge serves to provide a convenient and useful supporting floor between the sinks which are located somewhat apart from each other. The endmost sink, at one or both sides, is preferably provided with a drain board, constructed, mounted and connected in the same general manner as already described.

It will be understood, also, of course, that with either single or plural sinks, the drain board may extend to one or both sides, i. e., to the right or tothe left of a single sink unit, or of the endmost portion of one or both sinks, where a plurality are associated.

The construction, utility and advantage of the invention will be readily understood and appreciatedby all those familiar with the manufacture and use of similar culinary elements.' The manner of construction of the drain board provides continuous smooth surfaces, with rounded corners, and avoidance of any sharp corners or pockets tendingto collect foreign matter, or to interfere with cleansing of the surfaces.

Any pro ect ons or rou welded seam a may be ground oif or other- .wise removed, so as to render the interior surface smooth,-after which'it may be covghness along the ered with any suitable coating material, as

an enamel finish, or tincoating, or hot galvanized treatment. Due to the close ]01IltS and continuity of surfaces, by reason of the joint connection with the sink itself, such' boards, a continuous blank forming a dou ble-sided square top back, and a one piece bottom and front wall with the inner end of the bottom turned down for attachment to a sink rim, and an outer end wall having an inwardly curved lower edge welded to and flushing with the bottom and welded to the back and front wall respectively.

2: In the construction of sheet metal drain boards, a continuous blank forming a double sided square top back, and a one piece bot-v tom and front wall with the inner end of the bottom turned down for attachment to a sink rim, and an outer end wall having an inwardly curved lower edge welded directly to and forming a flush extension of the bottom, bent upwardly and provided with an outwardly turned rim, and welded to the back and front wall respectively.

3. In the construction of sheet metal drain boards, a continuous blank forming a back having outwardly turned top and end flanges, the end flange being adapted for connection with a similar end'flange, the blank being bent forwardly to form a longi-tudinally sloping bottom inclined upward- 1y towards the outer end of the back and bent upwardly at the front to form a shallow sloping front wall having a front rounded rim, an outer end wall having an inwardly curved lower edge welded to the bottom, back and said front'wall and its rim, an inner downwardly turned edge forming an attaching overlap connecting terminal for the bottom opposite the end wall, and a tongue extension of the back above said overlap terminal.

4. A sheet metal drain board formed of a continuous blank having an upwardly extending back provided with a rearwardly extending connecting flange for attachment. to

wardly extending front wall having an outwardly turned rim sloping doWvnwardl y from its outer end towards said termina and havingha projecting concave end for fitting over t e rounded rim of a sink.

5. The combination with a sink having a rounded upper rim and a rear splash wall extension of sheet metal, provided with a flanged end of a drain board formed of sheet metal avin a rear splash wall extension provided wit a flanged end, bolts conrim of the sin 6. The combination with a having a accepts.

vtowards the roun ed-rim 0 rounded front upper rim and a rear splash wall' extension of sheet metal provided with a flanged .end, of a'drain board formed of sheet metal havin a rear splash wall extension provided wit a flanged end, bolts connecting said flanged ends, an integral forwardly extending inclined bottom in front of the splash wall havin a front wall rounded at the to and S10 mg downwardly the sink, a similar end wall having continuous welded connection with the splash wall, bottom and front wall; a downwardly turned delivery end for the bottom lapping over and secured to the rim'of the sink, and a downwardly turned extension" of the rounded top front wall of the drain board fitting upon the rounded rim of the sink.- Y

In testimony whereof I hereunto aflix my signature. a
