Letters Patent No. 88,219, dated March 23, 1869.

IMPRO'VED SINK.

The Schedule referred to in these Letters Patent-and making part of the Ilma.

To all whom it may concern Be it known that we,WILLIAM SEAMAN andGEonGE A. BANTA, of the city and State of New York, have invented, made, and applied to use, a certain new and useful Improvement in Sinks; and we do hereby declare the following to be a f'ull, clear, and exact description ofthe said invention, reference being had to the annexed drawing, making part of this specification,l

wherein- Figure lis a plan of' said sink, as separated from the wood-work, and

Figure 2 is a vertical transverse section, the woodwork being shown in red lines.

Similar' marks of reference denote the same parts.

Sinks heretofore made, and adapted to being surrounded by a wooden casing, have had a flange projecting around the upper edge, to pass beneath the wood-work.

From the shrinkage ofthe wood,.there is an opening quickly formed between the metal sink and the wood-work, into and through which wat-er splashes, and this is particularly the case at the back part of the sink; and from the moisture and drippings, the oor below is constantly saturated, and frequently rots.

The nature of our said invention consists in a groove around the fiange ofthe sink, with return-channels into the sink, so that the water that splashes in between the fiange and wood-work will run back into thesink; and at the back we form a vertical flange, at the edge of' the horizontal flange, so as to set up behind the vertical back casing of the sink.

We have shown our invention as applied to a square sink, but it may be used upon corner and half-circle low water that splashes in between the wood-work and the flange to run back again into the sink.

e is a vertical flange, on the edge ofthe ange d, at the back of the sink.

f is the front, and g, the horizontal casing of Woodn work enclosing the sink; and

h. is the wood-work at the back, extending up agains the wall, and behind which the flange c sits, so that any water that splashes against the wood-work h will run back into the sink, instead of' soaking and splashing down between the wood-work and horizontal flange d, as heretofore, and wetting the wall or floor, or both.

The strainer-plate usually employed over the wastewater pipe is fiat, or nearly so; hence all floating substances, such as tea-leaves, potato-skins, oto., are washed into the strainer, and clog up the openings. To prevent this, we make a cavity, i, in the bottom of the sink, and employ a dome-shape strainer, k, so that any foreign substances may pass into the eavityz', and the upper part of the strainer remain free for water to run away.

The dome-shaped strainer contains more area for thc reception of perforations than a flat strainer.

What we claim, and desire to secure by Letters Patent, is-

1. The metallic sink, formed with the grooves 3 and Vchannels 2, in the fiange d, and the back flange e, upon the edge of the flange (l, as and for the purposes set forth.

2. The metallic sink, formed with the cavity c', and dome-shaped strainer lc, as and for the purposes set forth. s y

I n witness whereof, we have hereuntoset our signatures, this 25th day of April, 1868.

WILLIAM SEAMAN.
