By virtue of this construction it is possible to locate the vspout outlet directly above the drain hole 35 without requiring the use of a spout of excessive length or overhang from the splash-back to the 15 fluid receiving bowl.

The latter comprises in drainboard portion 32a of the embodiment of the ?nished sink a back ledge or shelf 2i and a Fig. i and is provided with beads such as 58, 53. continuous rim 22, 23; 2t merging smoothly into The narrow ledge 52b has a width preferablyv the shelf and all forming a co-planar horizontal equal] to that of the ledge 52c and ledge 52d. Referring to the embodiment illustrated in Fig. -35 surfacasurroundingthe main and sub-basins. In the bottom of said main basin 30 there vis formed . 5, the structure herein shown is a left hand sub a second basin or ?uidreceiving bowl 3!, which I basin sink di?‘eri'ng from the structure of Fig. 3 term the sub-basin. It is an important feature by the arrangement of the sub-basin Si in the of my invention, that the bottom of the main basin bottom 82 of the main basin 89. As can be. clear- ' 30 extends around all four sides of said sub-bean , ly seen in Fig. 5, the sub-basin 6| is arranged ’ 3|, the corresponding parts of said bottom being indicated by the characters 32a, 32b, 32c and 32:1. The ‘back edge of the. horizontal portion 20 merges seamlessly’ into an upright or vertically 45 extending splash-back indicated generally by the numeral so. The face 4! of said splashiback .09 may be suitably embossed,‘ such for example as in dicated by the panel embossing 62. A desired number of suitable faucet and spout holes-l3, 48, 50 is provided in the splash-back. At its top and ends the splash-board Ml is provided with rear wardly extending ?anges such as 46, 45. and M, which ?anges are in turn provided with narrow wall ?anges 41, 48 and 49, respectively (see Fig. 17). The ledge 2! which extends between the 40 at the left hand side of said bottom 52, the nar row ledge 82a corresponding to the ledge 52?; of the structure shown in Fig. 3 while the sloping portion 62b is provided with beads such as 83, 83 similar to the portion 32b of the structure of Fig. 1. Horizontal ledges 82c and 82d formed as a 45 Part of the bottom 62 of the main basin 80 are located along the front and the back walls of said sub-min 6i. As in the previous embodiments the main basin extends at all four sides of the sub-basin.‘ It will be clear “in view of the foregoing, that my novel sink - many advantageous fea tures not found in previous structures. Pro vision of the wide back ledge or shelf which is a ' ' main basin 30 and the splash-back 40 is made of ' continuation of the top horizontal surfaces of the such width as to permit its use as a shelf for such surrounding rim provides a conveniently located articles as. glasses and the like.' The continuous _ ‘?at horizontal surface upon which articles, such rim portions 22, 28 ‘and 24 which extend around the front and sides of the main basin 3!! are pref erably made somewhat narrower than the shelf ill. The horizontal rim portions 22, 23, 24 are turned'downwardly to provide a continuous seam less depending apron, the respective portions whereof being designated by the numerals 25, 2B and 21. The lower edges of said apron are-pro vided with a substantially horizontal, continuous inwardly extending ?ange such as indicated at 20. ~ The bottom 32 of the main basin 30 is prefer 70 ably made slightly sloping toward the sub-basin 3|, and it-is provided with a number of suitably disposed drain grooves or beads such as It, 33. In the structure shown in Fig. 1 the sub-basin 3! ~ is located substantially in the middle of the hot tom 32, and said beads 33, 33 are arranged in as glasses and the like, may be safely and conven iently placed without interfering with the use of ' the basin and drainboards. 0 Figs. '7 to 10, inclusive, illustrate preferred steps in the method of forming the sinks in accordance with the invention from a single sheet metal blank. In fabricating the double drainboard sink 66 of Fig. 1 a single sheet metal blank ‘I0 is placed ‘ in a suitable press and the central portion is preliminarily drawn to provide the sub-basin 3|, as illustrated in Fig. '7, this being accomplished by a suitably shaped dies. In a succeeding'oper ation the blank is operated upon in suitable dies to form simultaneously the main basin 30 and the drain beads 88in the bottom 32 thereof, as illustrated in Fig. 8. In the same or succeeding operationsthe sub- ti may be re-struck 1b I 2,127,559 and completed as to shape and depth, as well as ‘embossed for the drain hole 35 asindicated-at 35a, and its bottom made sloping toward said embossed portion, as illustrated in Fig. 9. Fig. 10 there is shown a blank for the right sub basin sink after similar operations have been V In accordance with the next preferred step in the method, the blank is preferably rough trimmed around its edges 1 I, and a suitable shape facilitating further forming operations is given to the corners ‘I2, ‘I2 thereof. ‘- Fig. 11), thus simultaneously forming the shelf 2| and the face 4| of the back panel or-splash ,_ by a corresponding narrow ledge and shoulder. This construction‘ prevents, to a considerable ex tent‘, splashing of water from the ?uid bowl over . the ?at, rim. ' The back shelf and rim merge smoothly into one another and seamlessly into ' the splash-back thus providing a smooth seam less surface, free of welds, which may be enamel 10 coated satisfactorily in production so/a's to be free from unsightly blemishes. ' In the following operation the metal in rear of the upright back wall of the sub-basin 3| is formed or bent up along the line ‘It, ‘It (see board 40 (see Fig. 12). continuous narrow ledge and upright shoulder“ forming part‘ of the primary basin and is also separated from the ?at top back ledge or shelf _ In performed thereon. 3 > For forming the top, and end ?anges 44,45 and I claim: 1.
