1 The present invention relates to a sink structure and to a sink bowl and drainboard assembly designed for economical sink production and to facilitate the installation of the sink and to obtain important advantages and economies incident to the special design and structural features including a special fastening therefor.
Important of the advantages incident to the present improvements are the permissible making of the sink or bowl as a single piece of Monel metal or stainless steel in a single deep drawing operation while retaining its formed contour, greater facility in the installation of the bowl in the sink and drainboard assembly incident to the mode of assembly thus permitting a 1 home owner to make his own installation without the requirement of a highly skilled artisan, added facility in the securing of the sink bowl in its assembled relation by the employment of improved fastening means of special design to permit of convenient positioning andtightening to obtain a rigid and durable assembly of pleasing and unbroken unitary appearance.
In the manufacture of one-piece sink bowls of stainless steels or alloys such as Monel metal as heretofore practiced in the production of deep drawn bowls of generally rectangular type it has been found necessary to employ a multiple step drawing operation with intermediate annealing so as to avoid unbalanced stress deformation or buckling of the side walls in the finished product. The method as commonly employed, which consists of a first draw, then annealing followed by a final draw not only involves multiple operations in the forming of the bowl but further, incident to the annealing, requires cleaning to remove the oxide prior to the final draw and additional polishing work to remove the oxide film to obtain a satisfactory finished product.
In accordance with an important feature of the present invention the bowl is made of a special formation or design which permits of its being produced as a finished product in a single or one draw operation. To this end, the bowl of substantially rectangular form, has each of its side walls slightly arcuate in contour thereby to be of a form to resist deformation as a result of unbalanced stresses set up in the drawing operation. Inconsequence of this arching and associated enlarged radius corners, the bowl may successfully be produced with substantial economics in a single drawing operation. As will be apparent very substantial economies are efiected, particularly as related to the elimination of the heretofore required step of annealing with the resultant necessity of cleaning and polishing. Moreover, the arching or curving of the side walls in arresting deformation from the pressed contour, in addition to permitting single draw production, offers a further and permanent advantage in added resistance to deformation of the bowl in handling and shipping. I
Further features of the present invention include the forming of the sink or bowl with a marginal, horizontal flange on its upper edge adapted to bear upon the upper surface of a drainboard or sink deck thereby to provide an integral marginal molding and further operating as a clamping means in cooperation with a simplified and adjustable fastener or securing device. The latter comprises bearing plates welded to the outer side wall surfaces of the bowl and formed with relatively shallow sockets for the reception .of detachable bracket members providing bearing support for clamping bolts positioned to engage the under surface of the sink deck and extended downwardly and formed for easy manipulation in the. securing of the bowl. The bearing plates and brackets are of special formation to permit of their being economically stamped from sheet metal.
An object of the invention is to produce a unitary sink bowl structure adapted to facilitate its installation without the requirement of a separable molding to effect a satisfactory joining with a supporting deck surface.
Another object of the invention is to provide a single piece sink bowl of substantially rectangular form which is adapted for economical production by a single deep drawing operation and which will retain its form when so produced from commercial stainless alloys such as Monel metal or stainless steel. 7
A further object of the invention is to provide a unitary sink bowl of substantially rectangular type wherein the side and end walls are of outwardly arched formation in a horizontal plane and are joined by a rounded corner formation of relatively enlarged radius thereby to permit of production by a single deep drawing operation and further better to resist deformation from its die shaped contour.
The invention further contemplates a sink bowl and drainboard or supporting deck assembly comprising a unitary sink bowl formed with an integral marginal and horizontal flange at its upper edge adapted to overlie the marginal deck surface when positioned in the usual deck.
cut-out and provided with bearing plates secured to the outer wall surfaces of the bowlwand adapted to pass through the deck opening. It further contemplates the employment therewith of special brackets for detachably engaging the bearing plates and the provision of clamping bolts carried by the brackets in position to engage the under surface of the supporting deck for clamping or securing of the assembly.
Other objects and advantages will become apparent from the following description taken in conjunction with the accompanying drawings inwhich:

Generally speaking the present invention contemplates the provision of a sink or bowl of single piece construction formed by drawing or pressing sheet metal of relatively light gauge and which may desirably be a corrosion-resistant alloy such as the alloy known under the trade-mark of Monel or other suitable corrosion-resistant metal alloy such as a nickel-chromium-iron alloy. It further contemplates an improved structural design and arrangement wherein the unitary sink bowl is formed with a horizontally extending upper marginal flange adapted in the assembly to provide an integral molding finish and to further function, in cooperation with a special clamping bolt arrangement, for rigid clamping of the sink to a supporting deck and within an opening cut therethrough. Moreover, in accordance with an important feature of the invention the unitary sink bowl is of substantially rectangular form having a specially modified side and end wall and corner structure designed to permit of substantial economies in the production of the bowl by a single deep drawing operation.
A preferred embodiment of the features of the invention is shown in the drawings wherein like reference numerals are applied to the corresponding parts in the several views. As shown therein the sink bowl, generally indicated by A, is assembled with a drain board or deck member I which may be of wood as customarily made having a linoleum covering 2 and is provided with a cutout opening 3 for the reception and positioning of the sink bowl to be assembled therewith.
In carrying the invention into practice it is preferred to make the sink bowl as a single piece of metal such as by drawing or pressing a sheet of corrosion-resistant alloy metal of a relative y 4 light gauge to form the sink or bowl of generally rectangular configuration. As best shown in Figs. 1 to 3 the sink bowl has substantially vertical side and end walls 6 and l united by curved lower corner portions 8 to the bottom wall 9 provided with the usual downwardly flanged drain opening Ill. The bowl is further formed at its upper edge with an outwardly projecting, marginal horizontal flange I l integral with the side and end walls and which may desirably be of a thickness of about /1000 of an inch. The flange II as shown, is of a width or outward extension from the side and end walls to provide for a substantial projection outwardly from the walls so as to provide a continuous molding of pleasing appearance. This flange II is designed for overlying engagement with the upper surface of the deck 2 at the frame of the opening to provide support for the bowl and to cooperate in the clamping of the bowl in a rigid installation. The provision of a flange of substantial width or projection from the body of the bowl permits of a wide tolerance in the formation of the deck opening without impairing the security and appearance of the final assembly.
As best shown in Figs. 1 to 3 the unitary sink bowl of my invention is, as viewed from above, of substantially rectangular formation but modified in the formation of the end and side walls 6 and I to have a convex curvature or slight arch-' ing in the horizontal plane and wherein the connecting corner portions l2 have a curvature of generous radius. As a result of this special design and contour an important production advantage is attained in that it permits of the production of a substantially rectangular type of bowl in a single deep drawing operation. The special contour of the end and side walls associated with the enlarged radius junction portion 12 permits of the economical single draw production of the unitary bowl. The side walls so formed are self-sustaining with relation to the formed contour and are of a character to resist deformation as a result of unbalanced internal stressing or surface stressing of the metal.- The contour of the bowl having side walls of arcuate formation enables the single draw productidii as will be understood by eliminating the necessity of relieving of unbalanced stresses incident to the deep drawing operation such as by annealing.
As an example embodiment of the improved bowl, as illustrated in Figs. 1 to 3, the bowl of approximately sixteen inches by eighteen inches was pressed to form from sheet Monel alloy of .037" thickness and having a bowl depth of seven inches. The rounded bowl corners 8 were formed of 2" radius while the vertical corner junctions of the side and end walls were formed of 3" radius. The outward curvature or arching of the side and end walls was to a degree of about one-half inch maximum deflection from normal or straight wall contour.
As best shown in Figs. 5 to 10 inclusive and in further accordance with the invention, there is provided a simple and effective means for securing or clamping of the bowl element to the drain or deck board so as to afford a firmly secured assembly of pleasing appearance and to facilitate the assembly operation that it may readily be performed by relatively unskilled labor. For this: purpose I have provided a clamping means for the securing of the bowl the supporting parts of which may be economically stamped and formed. of sheet metal and which will in the assembly permit of the bowl being passed through the deck.
opening so that its upper flange will overlie and bear upon the deck surface as illustrated in Figs. and 6.
The securing means is composed of sheet metal bearing plates I4 secured as by welding to the side and end walls of the bowl member as shown in Fig. 5. The bearing plates are formed as shown in Fig. 7 with integral outwardly depressed lower flanges I5 providing a socket and upper opposed integral flanges I-6 having inturned portions mutually providing a guideway socket hearing. These flanges are as shown of slight outward projection from the plates I4 so as to permit of the bowl with the plates secured thereto passing through the cut-out opening of the deck for assembling as shown in Fig. 1. In cooperation with each of the bearing plates 14, there is employed a separable or demountable bracket member, as best shown in Fig. 6, formed from sheet metal to have slidable interlocking engagement with the bearing plate I4 and to provide bearing support for a manually adjustable clamping bolt. To this end the bracket is formed of a flat 'metal body or rear wall portion I8 formed at its lower end with a depending lug or shoulder I5 of a size to be received within the socket formed by the lower plate flange I 5 and is formed adjacent its upper end with similar, opposite extensions or bearing lugs 2020 adapted to be slida'bly fitted within the socket formed by the plate flanges I6. For the purpose of retaining and providing bearings for the securing bolt, the bracket at its upper portion is formed with an outwardly bent and apertured ear 2| and to provide a lower bearing is formed with opposite and parallel side wall portions 22 turned outwardly perpendicular to the body portion and having upwardly turned horizontal lower bearing flanges 23 formed mutually to provide an aperture 24 for the reception of the clamping bolt 25. The clamping bolt 25, as best shown in Figs. 6 and 7, is received freely within .the upper and lower apertures of the bracket, is threaded for a substantial distance of its length and has threaded thereon a nut 26 positioned between the bracket walls 22 and to bear upon the inturned flanges 23. The upper end of the bolt passes through the aperture of ear 2I and its upper extremity is formed with a conical bearing enlargement 2! for engagement with the under surface of the supporting deck. As a result, when the bolt is tightened, a downward clamping pressure will be applied to the bracket, by the nut 26, for the ri id clamping of the bowl into position in cooperation with the overlying bowl flange I I. 'For added convenience the bolt 25 is extended below the bowl and has welded to its lower end portion a channel section hand grip lever member 28 for manipulation of the bolt in the tightening operation.
As will be understood from the structure of the tightening device as described, and as will be understood by reference to the dotted lines in Fig. 2, upon loosening of the securing bolt the supporting bracket I8 may be lifted sufficiently to effect withdrawal of the lugs 20 and I9 from securing position within the sockets of the hearing plate thus permitting detachment of the bracket I B and bolt 25 assembly.
The simplicity and facility of installing the sink bowl and drainboard assembly will be best understood by reference to Figs. 5 to 7. As a preliminary operation the drainboard or deck is provided with the cut-out opening of proper size and form for positioning of the how]. This may readily be accomplished by the employment of a combined instruction sheet and pattern for outlining the required opening of a comparable size and contour to that of the bowl. After cutting out the opening, the bowl having the attached bearing plates I4, is lowered through the opening until its marginal flange II bears upon the upper surface of the deck portion framing the opening. The separable or demountable brackets having the bolts 25 assembled therewith are adjusted to the permissible retraction of the bolts and then inserted from below to the upper dotted line position as shown in Fig. 2 and then lowered within the sockets I 5 and I6 of the bearing plates. Upon subsequent tightening up of the bolts by means of the hand levers 28 engagement is effected with the underside of the deck, incident to the inclined positioning of the bolts. Final tightening will effect rigid securing of the bowl with downward pressure of the nuts 26 on the bracket flanges 23, simultaneously securing the brackets in retained or interlocked relation to the bearing plates. As will be noted the side walls 22 of the bracket operate to retain the nuts 28 from rotation. As a further advantageous feature of the securing device assembly, the arrangement provides that the flanges 23 shall have a rest bearing upon the upper surface of the socket offset flange I5 thereby to resist the stresses by metal on edge for added strength.
In the disclosed structure the relative thinness of the light gauge metal from which the bowl is formed provides a flange II adapted to produce a molding joint between the bowl and drainboard which is substantially flush with the surface of the latter and as will be understood if a fully flush construction is desired it may be obtained by suitably countersinking the composition deck material at the marginal edge of the opening for a depth corresponding to the thickness of the flange.
It is to be observed that the present invention provides a unitary type of sink bowl designed to simplify its installation without the requirement of highly skilled labor. It, moreover, provides a structural design of unitary sink bowl of substantially rectangular type wherein the side walls are of special formation to permit of the economical production of the bowl by a single deep drawing operation. It is thus of a character to retainits pressed form without danger of buckling or deformation of the wall incident to the stressing of the metal and to thereby eliminate the necessity of annealing and the costly operations incident thereto. The invention structure further provides simplified and effective means operative in conjunction with the bowl flange for rigid clamping of the sink bowl in its assembled position.
Although the present invention has been described in conjunction with preferred embodimerits, it is to be understood that modifications and variations may be resorted to without departing from the spirit and scope of the invention as those skilled in the art will readily understand.
Such modifications and variations are considered one straight edge 30 to adapt it for a twin-bowl assembly as illustrated.
