Brey, Pittsburgh, Pa., assigner to Tracy Manufacturing Company, a corporation of Pennsylvania Application August 2, 1934, serial 10,138,087 15 claims. (c1. 41s7i This invention relates t'o a sink structure for installation in kitchens, pantries, lavatories, and generally similar localities.

A primary, and general, object`of my invention is to provide'a sink structure 'in which the drain board, and splash board, if one be included, are made of composite material comprising a rigid base material such as metal, and a covering of suitable non-metallic material such as linoleum, rubber, cork composition, fiber, micarta, or the like, with all edges and joints firmly and neatly bound.

A specific object of myinvention is tov provide at the region iny which the sink basin is attached to the drain board, or tableportion, of the sink structure a compact and relatively heavy 'binding which is'arranged to embrace and hold to each other at their edges the metallic base and non-metallic covering of the drain board or table, and which is arranged cooperatively with clamps to engage and seal the edge of the basin.

Another object of the invention is to provide binding which bridges over` the joint line between the non-metallic covering of the splash board and the non-metallic covering of the drain board, or table, of the sink, and which firmly interengages these coverings.

Another object of the invention is to provide simple but efficient means for rmly engaging and protecting theedge of the drain board, or table, of the sink structure.

v'A still further object of the invention is to provide a sink structure having binding for the locations and purposes indicated which isattractive in appearance, contributing in detail and in general effect to the production of a sink of particularly pleasing appearance.'

In the accompanying drawings Fig. I is a top plan view of a vsink embodying my improved structural features.

Fig. II is a bottom plan view of the sink, showing the attachment of the sink basin to the drain board, or table portion, of the sink.

Fig. III is a cross-sectional View on an enlarged scale, taken on Athe plane III- III of Fig. II, showing in detail the structure for attaching the sink basin, with an edge binding, -to the drain board, or table portion, of the sink, and showing the means for binding the joint between the covering elements of the splash board and the drain board, or table portionof the sink.

Figs. IIIa and IIIb are fragmentary cross-sectional views, on the scale'y of Fig. III, illustrating modifications in means for sealing` the joint between the sink basin and the edging, or binding, element at the edge of the drain board surrounding the basin.

Fig. me is a cross-sectional view illustrating on a materially enlarged scale the attachment of the basin to the drain board, and the common 5 y means for sealing the joint between the basin and drain board and for binding the edge of the drain board surrounding the basin.

Fig'. IV is a cross-sectional view taken on the line IV-IV of Fig. I,V but on a larger scale than 10 that of Fig. I, illustrating particularly the binding at the outeredge of the drain board, or table portion, of the sink.

Figs. IVa and IVb are fragmentary cross-sectional views illustrating modiflcations in the edge l5 binding shown in Fig. IV.

In Figs. I and II of the. drawings, reference numeral I designates the drain board of the sink, and reference numeral 2 designates. the sink basin. In these figures of the drawings, reference numeral 3 designates the splash board of the sink.. The splashboard 3 comprises a sheet metal base 3a, and a covering, or facing, 3b; and the drain boardl comprises a sheet metal base la and a covering lb. l

It will be seen in Fig. III of the drawings that the metal base 3a. of the splash board is pro-l vided with a fiange 3c, which extends at right angles to, and parallel to, the plane of the base, and that it is fastened by rivets 3d with metallic base la of the drain board, which in this region embraces a wooden Stringer 4. A head strip 5 is mounted to crownv the splash board. This head strip of suitable, lightl gauge metal has a depending foot 5a fastened by rivets 6 to the por- 35 tion of fiange 3c of the base which parallels the body of the base, and a depending flange 5b, which depends over the upper edge of the nonmetallic covering 3b, and seats in a rabbeted region therein. This head strip, or crown, 5 is 40 sprung into engagement, desirably by a slight difference in angularity between its foot 5a and flange 3c of the base. It may, however, be riveted in position, as shown, because the covering 3b of the splashv board is not subjected to wear or 45 injury, and it is therefore unnecessary that it be readily replaceable. The means employed for binding the side edges of the splash board will be hereinafter described.

It .will be noted that the non-metallic covering 3b on the splash board and the resilient covering lb, onv the drain board are so mounted on their respective bases that they are not in actual contact with each other at their adjacent edges. The interval 60 between the'edges of these covervthe bolt.

nintermediate region lc of the strip 1, a bolt 8 is threaded to the strip. 'I'his bolt 8 lies in the interval 80 between the covering elements Ib and 3b, and projectsthrough an opening 8 in the base 3a of the splash board. 'Ihe bolt 8 also extends through a ferrule III, against whichy bears a nut II-on the rearward, also threaded, terminal of Reversel threads being provided at the opposite en'ds of bolt 8, strip 'I `is drawn into firm engagement with the rabbeted seats of the covering elements 'by tightening action of nut II, and the edges of the cover elements are clamped closely to the respective bases by the pressure of the lImmediately c :ooperativeA means are provided fQr-engag'ingthe basin 2 yto the drain board 3, to be suspended' therefrom, to bind the edge of the drain board to surround the basin, and'to seal the margin of the basin. As shown in Fig. III, such means comprise U-shaped brackets. I2, each havfing one leg thereof adapted to bear against the under surface of the metal base Ia of the drain board, andits other leg adapted to bear against the under surface of a flange 2a, which'extends angularly upward from the body of the basin.

An edging strip, or-bar, I3 is arranged to bear against-the upper surface of basin ange 2a, in

In order to seal the `ioint between the basin 2 and the edging bar, the edging bar is provided in its under face with'aI gutter I5c,'which provides forward and rearward edges for contact with the basin ange, and which provides a seat for packing. As shown in Figs. III and IV of the drawings, a tube I1. of rubber, or

V`other yielding materials of which lead is a desircompressible material, rather'than as tubular in form.

the basin flange 2a is identical with that of Fig. ma. The edging bar 20v is,however, provided with two gutters, each of which receives abody 2I of packing.

The edge of the drain board may be formed in the various .ways-.shown in Figs. IV, IVa, and lIVb of the drawings. Referring particularly lto Fig. IV, it will be noted that the outer edgeof drain board covering Ib is rabbeted at 22 in a manner similar to that employed at thef edge of the drain board surrounding the basin 2. In this The edging'strip L23 is of relatively light gauge resilient meta-i, and has asecond leg 23h arranged to embrace afoot 24a, which extends perpendicular to a'skirt 24 on the drain board base Ia, andv winch lies along the under face of a wooden stringer 25. -In order thatedging strip 23 may be locked -resiliently in its edge binding position, there should be a diiference in anguiarity between thenangef- 24a of skirt 24 and foot 23h of edging strip 23. In the drawingsthis is shown as provided by 'aslight upward extension of foot 23h-to form an iacute angle with the vertical portion of the strip, whereas flange 24a is perpendicular tol thebdy ofskirt 24.. 'I'he leg 23a of edging strip 23 is bowed upwardly and a "woodenstrip 28, which is approximately hemispherical in cross-section, is 'fitted I into the underlying concavity of leg 23a, and is lightly cemented thereto. It` issuiiicient lthat seat 22A engages a leg 23a of an edging strip 23.

the strip 28 of-wood,`or other suitable material or composition, be lightly attached to edging strip 23a, as it is necessary merely that it be held thereto in mounting the strip on the edge of the drain board. Y

As mounted at the edge ofthe drain board, the iiat under face of "the .filler strip- 26 lies on vthe upper surface of the covering in the rabbeted` edge region 22'of,the,covering. As the iiat'face As shown 'in Fig. IV, the foot 23h of the edgy ing strip'is held against slippage fromits engagement with vflange 24a by a driving screw. which extends "through the foot and flange and enters the Stringer 25. This 'engagement is light, and does not force i'oot 28h into a position parallel with ilange 24a. The resilientl clinching ef- 20 In the modification of Fig. IIIb, the form of `It will be noticed that bolt 29.

fect of the edging strip is thus unaffected by this additional attachment.

The modification illustrated in Fig. IVa of the drawings shows a structure in which a stringer, such as the wooden stringer 25, is not used. In this modification there is an additional change in the resilient engagement of the edging strip with the drain board.

As shown, the skirt 21 depending from the edge of the metal base la of the board has a flange 21a which extends downwardly to a slight degree to form an obtuse angle with the body of the skirt. The edging strip 28 is identical in all respects to the edging strip of Fig. IV, save that the foot 28a extends perpendicularly to the body of the strip. The slight downward inclination of skirt fiange 21a thus gives the difference in angularity for clinching the edging strip resiliently to the drain board.

A bolt 29, carrying a nut 39, engages foot 28a of the edging strip with flange 21a of the skirt 21. also, does not force foot 28h into a position parallel to flange 21a, but that this engagement is sufficiently light to permit the resilient clinching of the edging strip to the drain board. 1

The structures shown in Figs. VIV and IVaare those preferred in binding the outer edges of the drain board.l It is to be understood that the features illustrated in both are interchangeable That is, the manner of obtaining difference in angularity between the edging strip foot and the skirt flange may be used when a wooden Stringer is employed, and conversely.

A simpler form of edge binding, which may be used at the outer edge of the drain board, and which is preferred as edging for the vertical side edges of the splash board, is shown in Fig. IVb of the drawings. The edging strip 3|, shown in this figure of the drawings. has a foot 3lb resiliently embracing ange 32a of a skirt 32, and attached-positively thereto by a bolt 33. l The upper lcg 31a of the edging strip. however, extends perpendicularly to the body of the strip, and lies directly and iiatly against the upper surface of covering Ib in the region of a rela; tively shallow rabbeting therein.

`As applied to the outer edges of the drain board I, a single length of stripping desirably is used along the front edge, and along each side edge. These strips may be mitered at the regions of their end abutment, and may be there welded or soldered to each other.. The edging strips 3l, as used along the side edges of the splash board, may also be cut terminally to the contour of the crown strip 5 at the top of the splash board, and welded or soldered to it.

it should be understood that side boards may be added to the sink assembly to meet the back board of the sink structure. If the splash board assembly of the structure is made to comprise side boards, as well as a back board, the junction lines between the drain board and the side boards, and the junctionV lines between the side boards and the back board, are bound interiorly of the structure by bridging strips similar to the bridging strip 1, which binds the junction line between the drain board and the back board.

To summarize my invention: a sink structure comprising a splash board and drain board of sheet metal are both provided with layers of suit` able covering material. -A basin is mounted on the drain board, to lie below the level thereof. The edges of both the splash board covering and the drain board covering are rabbeted along their edges and metallic binding strips resiliently, or by external pressure, are mounted positively to clamp the coverings to the metallic bases of the splash board and drain board. The adjacent edges of the drain board and splash board are not only held to their respective bases, but the joint line therebetween also is finished off by a binding strip common to both coverings.

The various forms of odge binding used, each form adapted to the location in which it is apiii plied, cooperate in the assembly to produce a sink structure in which the covering elements of linoleum, or the like, are protected against wear, and are held positively against separation from the metallic base elements on which they are mounted. They cooperate in producing an assembly of highly finished, and particularly pleasing, appearance.

The edging strip structure is made the subjectmatter of a divisional application Serial No.

The edging strips binding the outer edges of the drain board, and the edges of the splash board, are desirably, though not necessarily, made of stainless steel, or chrome plated metal.

i plying metallic edging strips to bind the edges of the composite material.

While it is highly desirable that the covering be in each composite plane element cemented tothe metallic base, for purposes of manufacturing convenience, and as a safeguard against intermedi.- ate bulging of the cover away from the base, I do not intend to limit my invention to' a structure in which the coverings are cemented over all or part of their area to the metallic bases on which they lie.
