To all whom/ it may concernf if Be it knownthat 1, JOHN F. KELLY, a citi--' zen of the: United States, residing at Trenton,

countyof Mercer,State of N ewJ ersey, have invented certain new'anduseful Improvements in Lavatory-Basins; and-I do hereby declare the following to be a full, clear, and exactde- 11 scription of the invention, such as will enable others skilled in the art to'which it appertains to make and use the sarne'.

' Theinvention relates to lavatory-basins that are made out of porcelain, clay, or other plastic material. Y As now constructed these basins comprise a bowl and an outlying ledge or table-like slab, which surrouiidsthe bowl and extends horizontally outward at'varying distances from the bowl, The slab is integral with the bowl, and the basin is formed corn plete when thematerial of which it is composed is in a'plastic states It is then putin the usual saggar and baked. or burned in a kiln to-harden it,afterwhich'it is glazed and again fired inthefurnace to set the glaze and give the basin the customary enarnel finish. In the manufacture of these basins considerable difliculty has been encountered in preventing the slabsfrom-warping, and they have been provided with curtains or flanges running around'their edges forthe twofold purpose of' stiffening the slabs to prevent them from warping during the baking process and to give the completed-basina more substantial and artistic finish. Theseflanges need to be supported while the {basin is imits-plastic state and during-the process of barking, and it has been proposed to extend them inward and connect them to the outer side of the bowl;

. but this connection to the bowl is objectionable, for the reason that the material of which the basin is composed shrinks considerably in the process of baking and the connection frequently pulls away from the bowl or cracks the bowl, particularly at those parts of the basin where the flange is farthest from the bowl and the connection is consequently longest.

Theobject of the present invention is to avoid the above-explained difficulties without departing from the accepted type of basin having the depending flange around the edge the-underside of the basin.

' of the slab and without depriving the flange of the support'which' is necessary to sustain it in the process of baking and prevent the warping of the slab.

Tolthis end theinvention consists generally in connecting or unitingthe flange to the under side of the slab outside of the circum ference of-the bowl instead of connecting it to the bowl itself. 1 Q In the accompanying drawings a well-known form of basin is illustrated having the invention-appliedthereto. 1 1

:Inthe drawings, Figure 1 is a plan view of Fig. 2'is a vertical'section taken across the basin through the center of the bowl, and; Fig. 3 is a sectional view showing in detail the manner of fasteningthe legs to the'basin. Referring'to-the views, a'denotes the bowl, b the ledge or slab, and 0 the marginal flange orcurtain extending around the slab and depending from its edge. The shape of the flange is unimportant, and it may extend straight down, as shown, at the back-of the basin or downwardly and inwardly, as indicated, at the front of the basin. As best shown in Fig 1, the basin'is usually of agenerally rectangular. outline; but the bowl is preferablyoval or circulan Con sequently the width of the slab; between the bowl and the flange varies considerably, being widest atthe back side of the basin and diminishing toits narrowest point at the front side thereof, The connection between the flange and the slab is shown-at In the cornpleted basin it is, in effect, a continuation of the flange, as shown in Fig. 2. In the process of manufacture, however, it is preferably a separate web of plastic material, which is united to the lower end of the flange; but whether made separate from the flange or by continuing the lower edge of the flange and turning it upward the invention is the same. Fig. 1 best illustrates the line where this connection is united to the slab. It extends-upward from the lower edge of the flange, as shown in Fig. 2, and is united to the under side of the slab, leaving the bowl free and without attachments to its surface. The con- Patented April 5, 1904. I i

nection need not extend from the extreme edge of the flange, but may be united thereto at any point, nor need the union between this connection and the under side of the slab be continuous all the way around. The advantages of the invention are best realized by keeping the connection free of the bowl at all points; but I should not regard it as a departure from the invention if in addition to the arrangement above suggested the connection (1 should be united to the bowl at the point where the shrinkage of the material during baking would be the least liable to fracture the union, which of course would be at the point where the union was shortest.

In Fig. 1 the letters 11. hdenote openings that are formed at the corners of the basin in the horizontal part of the connection (1. They are oblong and are preferably of the shape shown in the figure and serve the double function of permitting the escape of air from the space t', formed by the flange c and the connection 0?, during the process of baking and providing means for attaching the legs which support the basin. These legs areattached, as shown in Fig. 3, where 6 denotes a bolt having an oblong head corresponding in shape to the openings it and having a threaded lower end. The head of the bolt is passed through the opening and turned half-way around, so that it cannot be withdrawn. A washer f is then screwed or slipped onto the end of the bolt tightly against the under side of the connection, and the leg g is screwed up against the nut, jamming it against the connection. This closes the opening completely and secures the leg firmly in place without leaving any parts exposed and without the necessity of forming additional openings in the connection d for manipulating the fastenings. The construction being as thus described, it is to be noted that there are no recesses or partly-inclosed spaces underneath or on any part of the basin where dust, dirt, or vermin could collect, the closure of the openings h by the leg-fastenings above described making the inclosed space 2' perfectly tight all around the basin. Apart from the advantage of venting this space during the baking operation this is an important sanitary feature of the completed basin when set up.

Having thus described my invention, what I claim is- 1. In a porcelain or like lavatory-basin that is formed complete of plastic material and afterward baked or fired, the combination of a bowl, an integral ledge or table-like slab projecting outward from the upper edge of the bowl, a flange or curtain extending around and depending from the edge of the slab, and a connection extending inward from the flange and united to the slab outside of the circumference of the bowl.

2. In a porcelain or like lavatory-basin that is formed complete of plastic material and afterward baked or fired, the combination of a bowl, an integral ledge or table-like slab projecting outward from the upper edge of the bowl, and a flange or curtain running around and depending from the edge of the slab, said flange being extended inward and united to the under side of the slab outside of the circumference of the bowl.

3. In a porcelain or like lavatory-basin, the combination of a bowl, a ledge or table-like slab projecting outward therefrom, a flange or curtain extending around and depending from the slab, a connection extending inward from the flange and united to the slab outside of the circumference of the bowl, an oblong opening in said connection, a bolt with an oblong head passed through said connection, and a supporting-leg for the basin screwed on the bolt.

4. In a porcelain or like lavatory-basin that is formed complete of plastic material and afterward baked or fired, the combination of a bowl, an integral ledge or table-like slab projecting outward from the upper edge of the bowl, a flange or curtain extending around and depending'from the edge of the slab, a connection extending inward from the flange and united to the slab outside of the circumference of the bowl forming an inclosed space 2', and an orifice h in the connection forming a vent to the space 6 during the baking.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN F. KELLY.
