10 Claims.

The invention relates to sinks, wash basins and the like formed from sheet or plate metal and preferably covered by a protective coating, such as an enamel coating. More particularly, the invention relates to such products in which a fluid receiving bowl, together in some cases with one or more drain boards, terminates in a rolled rim and a comparatively high splash-back lying in a plane substantially at right angles to the plane of the top of the rolled rim, and are all formed in and from a single piece or blank of sheet or plate metal.

Enamel coated cast metal sinks and the like have been made, but the same, particularly in large sizes, are very heavy and require two or three men to handle the same in installing such sinks; and frequently the larger sizes require legs to prevent sagging or to prevent undue strain upon the wall where they are installed.

Sheet metal enamel coated sinks have heretofore been made in which the bowl portion and a high splash-back therefor are either bolted or welded together. However, the appearance of such sinks is objectionable either because of the exposure of bolt heads, or because of the difficulty of making a satisfactorily welded joint without having the same more or less noticeable after being enameled.

Sheet metal sinks have also been made in which the bowl is surrounded by a rolled rim and is provided with a high upstanding splash-back, all formed from a single sheet of metal. However, such sinks have always been provided with notches or openings at the place where the ends of the rolled rim meetthe splash-back, in order that the splash-back could be moved to an upright position by a bending operation, after which the cut edges of the slits or notches at the ends of the rolled rim, are welded together where the rolled rim meets the splash-back.

Such notching, slitting and welding operations are not only expensive, but the welded joint, in having a curved and recessed contour where the rolled rim ends and the spash-back meet, are always more or less noticeable and are difiicult to cover with a satisfactory enamel coating having the same properties as the enamel coating on the remainder of the sink.

Moreover, when extremely long sinks are made, as when they are provided with a drain board at one or both sides of the fluid receiving bowl, or when large fluid receiving bowls are provided, the plane of the upright splash-back has always been located substantially continuous with the plane of the rear fluid receiving bowl wall; and it is difiicult to maintain a truly plane surface for the splash-back when subjecting the sink to heat for enameling the same, since the unequal strains imposed upon the splash-back during the forming operations may cause a slight warpage or 5 Weaving of the splash-back when the same is heated in the enamellingfurnace.

Accordingly, it is-an object of the present invention to' provide an improved construction for sinks, wash basins and the like, which overcomes the difiiculties which have resulted in prior sink construction.

Furthermore, it is an object of the present invention to provide a sink and the like, in which a fluid receiving bowl, together in some cases with one or more drain boards, terminates in a rolled rim and in a; comparatively high splashback, and are all formed in and from a single piece or blank of sheet or plate metal without performing any notching and/or subsequent o welding operations at the place where the rolled rim ends merge with the splash-back.

It is likewise an object of the present invention to provide a stiffening ledge at the top rear edge of the bowl of such a sink formed from a single 25 piece or blank of sheet or plate metal, which stiifens the splash-back, and enables the splashback to be maintained in proper position without warping, weaving and the like when the sink is subjected to heat for carrying out an enamelling operation.

A further object of the present invention is to provide, in such sink constructions, a fluid receiving bowl having straight side walls, that is with the bottom thereof just as large as the top, to provide a maximum capacity for the fluid receiving bowl.

It is likewise an object of the present invention to provide sinks of such improved character, which may be readily coated with a preferably 40 acid resisting enamel coating of the highest quality, so that the resulting coating is absolutely uniform in appearance and characteristics throughout, and which enamel coating is not weakened at any of the working surfaces of the sink due to 45 previous operations in forming the sink prior to being enameled.

Amd finally, it is an object of the present invention to provide sinks incorporating the above described desiderata, which are very light in weight by being formed from sheet or plate metal, which are formed from a single blank of metal, and which are inexpensive to manufacture and have a pleasing and attractive appearance.

These and other objects may be obtained by the constructions, arrangements, combinations, elements and formations, hereinafter described in detail and claimed, preferred embodiments of which are shown in the accompanying drawing, which may be stated in general terms as including in a sheet metal'sink having a fluid receiving bowl preferably with substantially upright side walls, and in some cases having one or more adjacent drain boards, the bowl and drain boards terminating in a rolled rim and in an upright splash-back, all formed integrally from a single sheet of metal; a preferably laterally continuous stiffening ledge preferably substantially S-shaped in cross section formed between and merging into the bowl and splash-back to provide an offset thereat, and in case drain boards are provided adjacent to the fluid receiving bowl, a portion of said ledge extending between and merging into the drain boards and splash-back; the rolled rim being preferably continuous and surrounding the front and sides of said bowl and .drain boards if used, the ends-of the rolled rim terminating at and merging into said splash-back, the places of merger between the ends of the rolled rim being seamless, and the line of intersection between the ledge and splash-back lying in the plane of the upper portion of the rolled rim.

' Referring to Figs. 1 and 5 to 9, inclusive, the

improved sink shown therein may include a fluid receiving bowl l0, having a bottom wall ll provided with a drain opening 12, and having substantially upright or vertical walls, preferably substantially rectangular in cross section and ineluding a front wall l3, a rear wall 14 and side walls IS, with preferably rounded corner walls l6 therebetween. I

A drain board I! preferably provided with a multiplicity of parallel grooves 18 set closely together, is preferably located adjacent to the fluid receiving bowl III, and the drain board I! preferably slopes slightly downward toward the bowl l0 as best shown in Fig. 8.

The bowl Ill and drain board I! preferably terminate in a preferably continuous rolled or preferably lying in an upright plane.

For the purposes of the present invention, the fluid receiving bowl III, the drain board l1, the rolled\pim l9 and the splash-back 20 are all formed integrally from a single sheet of metal; and may be preferably made in accordance with the method set forth in my copending application entitled Process of making sinks, wash basins and the like, filed December 7, 1932, Serial No. 646,207, matured as Patent No. 1,916,910, dated July 4,

The outer portion of the rolled rim l9 may be preferably integrally extended downward to form a long skirt 2| surrounding the fluid receiving bowl in and drain board 11, as best shown in Figs. 1 and 6; or the rolled rim l9 may terminate in a short skirt 2|a, as shown in Fig. 3.

The ends or end portions 22 of the rolled ri l9 terminate at and merge into the splashback at 23; and a stiffening preferably continuous, ledge, generally indicated at 24, is formed between and merges into the rear bowl wall I4, the drain board l1 and the splash-back 20." The present invention involves particularly the improved construction of the sink at the places 23 and of the ledge 24.

The provision of the stiflening ledge 24, which is preferably parallel with the rear bowl wall 14, offsets the plane of the bowl wall I4 from the plane of the splash-back 20 and thereby provides an offset at the place where the ledge 24 merges'into the bowl and splash-back; and the ledge 24 is preferably substantially S-shaped in cross section, and slopes generally rearwardly upwardly from the bowl to the splash-back, as best shown in Fig. 9, and may comprise'a curved portion 24a merging into the bowl wall l4, and a flattened portion 24b, which merges into or intersects with the splash-back along a line 25, which line extends between the places 23 and lies in the plane of the upper portion of the rolled rim, as best shown in Figs. 6 to 9, inclusive.

As stated, the splash-back projects upwards from the rear of the fluid receiving bowl l0 and since the intersection of the same with the ledge portion 24b is the line 25, which line also passes through the places 23, the splash-back 20 may be originally formed horizontal in a one-piece sheet blank along with the bowl I0 and rolled rim l9,

. and may thereafter be bent to the upright position shown, along the line 25, without having to notch the sheet blank around the places 23. The

places 23, where the ends of the rolled rim l9 passes through the line 25, so that a fluid dropping to the drain boardwill flow along the same into the fluid receiving bowl in the usual manner.

The location of the ledge 24 and its substantially s-shape, together with the offsetting of the splash-back 20 from the rear wall l4 of the bowl l0 materially stiflens the sink and the splash-back 20 so that the correct location of the splash-back may be maintained in a vertical planewithout warping or weaving out of true when the sink is subjected to heating in an enamel furnace for providing a preferably acid resisting vitreous enamel coating thereon.

LikewiseJihe fact that the places 2: where the ends of the rolled rim ll merge with the splashback 20 are seamless and need not be welded, enables the improved sinks to be inexpensively made and enables a uniform enamel coating to be provided on the sink especially at the places 23.

Thus, the-present'improvements provide a very light weight sink formed from a single blank of metal which is inexpensive to manufacture, has

,a pleasing and attractive appearance, and is very strong in use.

The construction'shown in Fig. 2, is identical in all respects with that shown in Fig. 1, excepting only that a left-hand drain board Ha is provided, similar in all respects to the right-hand drain board l1; and the splash back 20b'extends in back of the fluid receiving bowl and both drain boards I? and Fla.

The construction shown in Fig. 3, is similar to or identical with the construction shown in Fig. 1 in all respects excepting only that the rolled rim i9 terminates in a short skirt 2 la.

The construction shown in Fig. 4, is the same as that shown in Fig.3, excepting only that the drain board is omitted and the splash-back 20a is shortened by the omission, of the drain board.

In the constructions shown in Figs. 2, 3 and 4 the ledge formation and the seamless merger of the roll ends with the splash back is the same as that shown in the remaining figures of the drawing.

In the foregoing description, certain terms have been utilized for brevity, clearness and understanding; but no unnecessary limitations are to be implied therefrom or from the use of such words in the claims; and such terms are intended to be broadly construed, as follows:---

The word sink used herein and in the claims is intended to include sinks, wash basins, wash bowls and the like; the word sheet metal" is intended to include sheet and plate metal of the desired or necessary gauge; the words rolled rim are not intended to imply arcuately shaped rims since the rims may have any desired shape and may terminate with either shallow or deep lar characteristics to enamel coatings, and the words enamel coated are likewise intended to include materials such as stainless steel and the like, which may have characteristics in use for the purposes of the present invention the same or similar to enamel coated sheet metal.
