11 Claims.
This invention relates to improvements in sinks.
It is a primary object of the invention to pro- Vide a novel and improved sink construction. in which the drain board and sink are integrally united in a joint which provides for drainage from all points of the drain board; which prevents or minimizes splash; and which makes possible a so-called seamless weld without requiring special skill and without risk vof injury tothe relatively thin metals or plies involved.
Other objects will appear more fully from the following disclosure of the invention.
In the drawings:
Fig. 1 is a view in perspective showing fragmentarily a sink embodying the invention.
Fig. 2 is a fragmentary detail view taken in section through a marginal portionof the drain board' l5.' f
Fig. 3 is a fragmentary detail view taken in section through an incomplete welded joint between the drain board and sink'.
Fig. 4. is a view similar to Fig. 3 showing completion of the welded joint.
Fig. 5 is a View similar to Fig. 4 showing a cornpleted joint where a multi-ply clad metal is used.
Like parts are designated by the same reference characters throughout the application.
The sink bowl and drain board assembly to which this invention relates is preferably made of stainless steel or other corrosion-resistant metal. The sheet metal stock may either be solid or may be clad with a ply of corrosion-resistant metal such as stainless steel which is to cover all the exposed surfaces.
The sink bowl 6 and drain board 1 are separately fabricated and are then welded together. The entire upper margin 8 of the sink bowl is formed inwardly on a radius to overhang the sink bowl, as best shown in Fig. 3. At the end of the sink bowl adjacent the drain board 1, the sink bowl is so cut that its upper margin is slightly concave as indicated at 8 in Fig. 1.
A complementary margin 9 of the drain board l is formed conveXly downwardly on a short radius as it approaches the sink bowl. This formation is also shown in Fig. 3. The edges 8 and 9 are then united by a Weld at I0. It is important to the invention that they, and particularly the margin 8, have the curve illustrated so that the two margins meet at an acute angle rather than at right angles in order that the weld l0 engages the marginal edges of both sheets of metal instead of engaging the edge of one and a face of the other.
The metal used in making the weld at I0 is the same metal exposed on the faces of the sink bowl and drain board. Thus, when the weld is ground off as indicated at IU in Fig. 4, no seam between the parts is apparent. The fact that the weld metal is applied alike to the respective edges to be joined (rather than to the vface of one and the edge of the other) is of particular advantage Where, as in Fig. 5, the sink bowl 6 and drain board 'l are made of sheet metal clad at l I with such corrosion-resistant material as stainless steel. The fact that the edges of the stock meet at an acute angle facilitates the making of -a neat seamless weld at i0' which will unite not merely the base sheets but the plies l l which clad them. But for this feature, the thin plies l I which might be burned away, thereby making a perfect seamless weld impossible. Because of the fact that the edge portion 9 of the drain board 1, opposite the center of the sink bowl 6, is forced downwardly to meet the concave marginal portion 8 of the sink bowl, the result is that all portions of the drain board 'l are pitched toward the center of the end of the sink bowl, thus assuring drainage from all parts of the drain board into the sink bowl. framing which supports the drain board are illustrated but, forming no part of the present invention, will not be described.
The inward curvature of the sink bowl at 8 throughout the perimeter of the sink bowl provides a very desirable anti-splash feature, turning back toward the interior of the bowl all water tending to follow upwardly along the side thereof. In addition, it facilitates the making of a neat seamless weld without requiring the high degree of skill which would otherwise be necessary. It also renders practicable the downward curvature of the drain board margin at 9.
It is a great advantage to have all portions of the drain board pitched toward the center of the end Wall of the sink bowl, such pitch being assured by welding the margin of the drain board to the bowl margin which is prefabricated in concave form as herein disclosed.
I claim:
1. A sink comprising a bowl and drain board in Welded connection, the upper margin of the sink bowl overhanging the bowl and the contiguous marginal portion of the drain board having a convex downward curvature to an edge coextensive with said bowl margin and provided with a Weld affording continuous connection between the bowl and drain board substantially along the line of maximum overhang.
Details of the- 2. A sink comprising a bowl and drain board having contiguous margins provided with a connecting weld, both such margins extending inwardly to overhang th'e bowl, the contiguous margins of the drain board and sink bowl being at an acute angle to each other at the weld.
3. A sink comprising a sink bowl and drain board having #margins provided with a seamless weld providing Avconnection therebetween, the sink bowl having its said margin curvilinearly overhanging the bowl at an acute angle to the contiguous margin of the drain board, the weld spanning the edges of the sink bowl and drain board along such margin.
4. The construction set forth in clalifm :3, in which the drain board and bowl both comprise sheet metal clad with a corrosion-resistant zply, the weld connecting the corrosion-resistant plies at the surface of the sink bowl and the ldrain board across the intervening edges of the sheet metal between such plies.
5. The construction set forth in claim 3, in which the upper portion of the sink bowl is concave in a vertical plane and the margin .of the drain board is formed downwardly to meet such concave edge, whereby all portions of the drain board are pitched toward -a central end portion ofthe board.
6. In a sink, the combination with' a bowl having its end `wall provided with a downwardly concave upper margin, of a drain board having a margin welded to the said concave margin of the kbowl `whereby the drain 'bowl `is..universal'ly pitched toward a central portion of the end of the bowl, the said concave upper margin portion of the end wall of the bowl having an inward curvature overhanging the bowl andthe complementary drain board margin being disposed at an acute angle to said bowl margin in cross section, and a seamless weld connecting the margins of the drain board and bowl and spanning all portions of such margins between the exposed faces of the drain board and the bowl,
7. The methodof manufacturing a sink having an integrally welded 'drain board and vsink bowl, suchmethod consisting in prefabricatng the .bowl with an inwardly curved overhanging top margin, applying a margin of the drain board to such overhanging bowl margin with the respecother, and lapplying welding .metal across `the @We margins exposed at an acute angle to each 50- Number exposed margins of the drain board and the bowl.
8. The method of manufacturing a sink having an integrally united bowl and drain board, which method comprises prefabricating the bowl, forming an upper marginal portion of the bowl inwardly to overhang the bowl, giving such margin a form which is vertically concave whereby such 'margm is lowest .at an intermediate point, holding the idrain sboard with its margin adj oining the said bowl margin at an acute angle and applying welding metal across the contiguous .bowl and drain board margins.
9. The method set forth in claim 8 in combi- .nation with' the further step of forming the drain ib'oardlmargin .conv-exly downwardly toward the bowl.
10..A.-sinkrcomprising a bowl and drain board, the 'bowl vhaving its upper margin curving inwar-'diy to overhang the bowl, the drain board having a margin meeting the margin of the bowl at an acuteanglle, and a weld `disposed in a position overhanging the bowl Iand connecting the said margins of the drain board and bowl.
l1. The combination 4set forth in claim l0 in which kthe bowl `and `drain board `.comprise sheet metal fclad `with a corrosion-resisting ply, the said plies vbeing innermost in the :bowl and uppermost in 'the idrain board Ion opposite faces of the respective margins where such margins meet at an acute angle, ,the weld being .of corrosion-resistant metal 'and completely covering the exposed ends of the sheet metal of the bowl and drain board and joining the said plies.
