PORCELAIN WATER GLOSET BOWL. No. 320,990.

UNITED STATES RICHARD HARTMAN WATSON, OF PHILADELPHIA, PENNSYLVANIA.

PORCELAIN WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 320,990, dated June 30, 1885.

Application filed April 17, 18H54 (No model.)

To all whom t may concern:

Be it known that I, RICHARD HARTMAN VVA'rsoN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in One- Piece Porcelain Water-Closets, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a vertical transverse section, with slight perspective touches. Fig. 2 is a transverse sect-ion at right angles with Fig. 1, and taken at two altitudes, the right-hand portion on the line x fr, and the left-hand portion on the line y y, of Fig. 1.

It will readily be understood that the whole top of the closet is true and level all around at one height, and the front and right and left sides are alike, and that the back is entirely smooth and free from any inwardlyoverhangi ng rim, and is convenient for cleanly wiping when it needs it.

The same letters indicate the same part in each view.

A is the bowl; B and C, outlet water-way from the bowl to the soil-pipe; Dhthe inlet water-way to the wash.

E is a tubular extension of the saine to both the right and the left1 upon one level, to the front of the closet, where the two streams meet again at the center c, and are both turned into the perforated passage F, which extends across the front and to both the right and left sides of the'closet, as shown on the right side in both Figs. 1 and 2.

G indicates what is called a fan77 or spreader It is a smooth thin porcelain H shows the curved inside corners, which are all alike, and differ decidedly from the outside angle of the bowl, as seen in Fig. 2. I obtain this contrast of inside and outside angles, as shown, by' means of a hollow wall.

I shows an air-space in the hollow in that part of the wall of the closet. This hollow diminishes down the side of the bowl and terminates smoothly in contour of the closet, so as to give no outward or inward indication how the difference in inside and outside angles in such a marked degree is accomplished. By this means the bowl is strengthened, and the inside is better tted or shaped for the wash, and the outside for the wood-work where it is to be placed.

J J are right and left ventilatingilues.

K K indicate openings downwardly into the bowl. Y

L L are pipe-[langes for ventilaiingpipe.

M indicates a porcelain lip extending down into the closet, so as to prevent water and paper from getting in'to the ail'passages from the closet to the Ventilating-pipes. I have found this to be an important matter, as the draft inthe Ventilating-pipe favors its own obstruction. M effectually guards the ventilating-flues.

Having thus fully described my improvements in a square-topped one-piece porcelain watercloset, what I claim as my invention, and desire to secure by Letters Patent, is-

A porcelain water-closet bowl constructed with double Walls in whole or in part, with air-spaces between them, whereby lightness is preserved, while the internal and external shapes are varied at pleasure, substantially as and for the purpose herein set forth.

RICHARD HARTMANNVATSON.
