invention lrelates 'to improved `sink and -vvorkV or drain board jstnucturet-and more 'par'- ticnla-rly discloses .means `for joining the meet'- ing or overlapping .edges of a `sink md Vdrain board such a manner :as Lto A.provide a `waterpr'oof seal therebetween.

Many# diiferent .structures have' been employed in an effort to create` .a waterproof'lzseal .as between. the `rirnor lliipof a sink and the adjoining or enclosing drain board. Presumably, many of these structures accomplish their intended purpose to some extent 4at least. However, it appears that, in an eiort to create a waterproof seal as between a sink and drain board, these prior struc tures have become increasingly complicated, elaborate and` difcult and costly to install.

The structure of the present invention vis believed to befsuch as to providethedesired waterproof sealasfbetween a sink andld-rain board edges and this, therefore, constitutes one of the objects and advantages.

Another object of the invention lies in the nprovision .of a .structure that readily adaptablefto the installation of sinks in work or drain boards, produced in either metal or wood, in such a manner as to provide a waterproof seal between the overlapping parts.

It is considered to be an important object of the invention to provide a waterproof jointure as between sink and drain board that is of simple construction, capable of easy installation, and inexpensive to manufacture.

Other objects and advantages of the invention will be more fully understood from a consideration of the following specification, taken in conjunction with the accompanying drawing; and in which Fig. l is a fragmentary perspective view of a sink and drain board installation embodying one form of the invention;

Fig. 2 is an enlarged vertical fragmentary sectional view, taken substantially on the line 2 2 of Fig. 1, and shows the method of attaching and securing the lip or rim of the sink to the drain board;

Fig. 3 is a fragmentary vertical View, partly in section, taken on the line 3-3 of Fig. 2;

Fig. 4 is a fragmentary vertical view, partly in section, taken on the line 4-4 of Fig. 2;

Fig. 5 is a fragmentary vertical sectional view, taken substantially on the line of Fig. 2, and shows the application of the invention to the installation of a sink or a wood or other thick drain board; and

Fig. 6 is a fragmentary vertical view, partly in section, taken on the line 6-6 of Fig. 5.

Referring more particularly to the drawing, the reference numeral I0 is employed to generally designate a sink and drain board installation' in which is embodied one form of the in- 2 Claims. (Cl. .f1-187) 2 vention.' In this `particular;illustration the drain board'- 'H is formed :of :sheet metal, and includes a .linoleum vor other suitable `top surfacing ma terial i2. In the illustrationl of Fig. 1-a sink :I3 isV mounted in an :aperture provided therefor in the metal .shelf Il and material I2.. This sink may be of any convenient shape yand proportions and includes. the conventional, rsubstantially upright walls Ill which, .at their ,upper edges, terminate in :angoutw-a-rdl-y directed .flange orri-m Il-6 along their anges I9 to the underv face of` thel shelf I-I. Each of thesebrackets includes a depending wall 2'! that terminates ina flangeq22- which projects into the aperture or opening 23 formed by the edges `of .the Vshelf and material, I.I andv I2 respectively. Permanently joined to the outer face of the wal-l 't4 'of lthe y.sink area corresponding. number: of brackets 24. brackets are preferably located with their ange 2li` extending laterally outwardly from a point adjacent the curved portion I1 of the sink. It will be noted that brackets i8 and 24 are so located that their respective anges 22 and 26 will be superposed substantially as shown. A suitable opening is made in flange 22 which, when the sink I3 is mounted in the shelf, is adapted to register with a threaded opening in the ange 26. A screw 21 projects through the flange 22 I' and engages the threaded opening of flange 26.

The material I2, adjacent the opening 23, is preferably of lesser thickness to provide a marginal depressed area or ledge 28. The depth of this ledge is equal to, or slightly less than, the thickness of the material of which the flange I6 of the sink is formed.

To assemble the structure embodying the invention, it is found desirable to provide a number of brackets I8 and 24, such as at least four, for the purpose of securing a sink such as indicated in the drawing. When these brackets have been attached, the sink is placed in the opening 23 and screws 21 are mounted, as shown. As the screws are turned down, the anges 22 and 26 are brought closer together and this action causes the flange I6 of the sink to have such pressure engagement with the somewhat compressible material I2 of the shelf top as to produce a watertight seal as between the material I2 and flange I5.

Referring more particularly to Figs. 5 and 6, it will be noted that a shelf 29, formed from wood or other material of substantial thickness, supports a linoleum or other surfacing material l2, and that this material is formed with a cut down Regardless :of `.any inclination of the' These marginal portion adjacent the sink opening 23, as previously described. The sink |3 and the attached brackets 24 may be similar to that described above. However, the shelf 29 is provided with flat brackets 3| corresponding in number to the brackets 24. Each bracket 3| is secured to the under face of the shelf 29 by one or more screws 32 and is so positioned that an end portion 33 thereof projects into the opening 23 to constitute an equivalent to the flange 22 described above. A screw 34 projects through an opening in bracket 3| into the threaded opening of the flange of bracket 24. This screw, as may be seen, is somewhat longer thanthe screw 21 and, when turned down, tends to draw flange 26 and bracket 3| together, thus causing flange I6 of the sink to have pressure engagement with the material I2 in a manner to produce a water-tight seal or jointure as between these overlapping parts.

Although applicant has shown and described only two modifications of the invention, it will be apparent to those skilled in the art that further modifications may be made in adapting the invention to other types of sinks or bowls, and that such modifications are contemplated as being part of the invention insofar as they are within the spirit and scope of the annexed claims.

Having thus set forth my invention, what I claim as new and for which I desire protection by Letters Patent is:

1. A structure of the class described comprising a sink having side walls, flanges terminating the edges of said walls, a shelf having an aperture of a size to receive the body'portion of said sink, a marginal portion of the edge forming said aperture adapted to be engaged by said flanges, a bracket permanently joined to said shelf and extending into said aperture, another bracket permanently joined to said sink and in spaced superl ture of a size to receive the body portion of said sink, a. marginal portion of the edge forming said aperture being adapted to be engaged by said flanges, a bracket permanently joined to the under face of said shelf and extending into said aperture, another bracket permanently joined to one of said sink walls and in spaced superposed relationship with said shelf bracket, the brackets having aligned openings therein, and a screw projected upwardly from beneath said shelf through said openings, said screw having threaded engagement with the walls of the opening in said sink bracket and being operable to draw said sink bracket downwardly to effect pressure engagement of the sink anges with the marginal portions of said shelf.
