WATER-CLOSET BOWL;

Patented my s, recs.

Application nae June 22,1905. seal in. 266,428.

To all whom it may concern.-

Be it known that 1, JOHN F. KELLY, a citizen of the United States, residin at Trenton, Mercer county, State of New ersey, have invented certain new and useful Improvements in Water-Closet Bowls; and I do hereby declare the followin to be a full, clear, and exact description 0% the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to siphon-discharge water-closet bowls, and has for its object to provide a closet-bowl of this general t. e that shall be greatly simplified, structure y considered, cheaper of manufacture, and noiseless and sanitary in operation and that shall afiord a lar er water-surface than has been found possi le in other bowls of this general character.

In the accompanying drawing, the figure is a vertical longitudinal section of a watercloset bowl involving the features of my invention.

Referring to the drawing a indicates the hopper of the bowl, having the gradually-inclined side walls I), which terminate in an outlet h, substantially centrally disposed with respect to the ho per. Near the upper rear edge of the bow 1s the usual coupling nipple or horn provided with the water-inlet assage c, which communicates with the liushin -rim d, which may be of any preferred f orm'and is illustrated as a hollow rim around the upper edge of the bowl provided with perforations to direct the water in jets Ever1 the interior surface or side walls of the By roviding the walls of the hopper with a gra ual downward inclination instead of the usual strai ht or substantially vertical side and rear we is, as heretofore employed in bowls of this general type, a much larger wator-surface is maintained in the bowl, which surface so nearly'underlies the open to of the bowl as to cover ractically all of the oper-walls that woul otherwise intercept and be soiled by the falling fecal matter.

Another important feature in connection with the special form of hop er is the previsionof the central] disposed? outlet h in the bottom thereof, w 'ch in contradistinetion to the usual wash-down bowl, in which the outlet is located at the front or rear portion of the hopper, causes all 01 the inatter to fall directly toward said outlet, thereby wholly avoiding the tendency of paper and fecal matter to adhere to the side during the flushing operation.

On one side of the bowl is located a siphondischarge passage e, the rear wall of whose intake-leg is formed by the inclined wall of the hopper, said intake and discharge leg being separated by the portion is, forming a dam which determines the de th of the water in the bowl. Said dischargeeg is bent backward alongthe base f until it joins the nipple or horn g,wh1ch serves as the connection for the usual soil-pipe. On the side of the bowl 0pposite the siphon-discharge passage e is a wator-passage i, whose inner wall is formed by the side wall of the hopper and Whose outer wall is formed as an integral extension thereof. Said passage 41 connects with the inlet-passage c and, as indicated, is directed downwardly and inwardly along the exterior of the ho per and terminates in a constricted jet-ori ce which delivers a powerful stream or jet of water against the concave bottom I of the bowl immediately below the dischar eopenin h in the bottom of the hop er. T 's jet-or' ee' is located so that it lies eiow the edge or rim of the opening it, which insures said 0 ening always being below the lowest possib e level of water in the bowl and likewise maintains a considerable body of water in the passage, which conditions render the operation of the jet in the flushing o eration practically noiseless. The jet or ori ce is located directly opposite the intake end of the siphon-discharge passage e, so that it not only delivers a strong 1st directly into the siphon to start the same, but immediately swee s out all matter that has accumulated in t e loottom of the bowl and creates a heavy transverse stream, which materially assists the suction of the siphon-discharge to clear all matter from the bowl in the shortest possible period of time,

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is v 1. An integral water-closet bowl, comprising a hopper having its sides gradually inclined to a central outlet, a siphon-discharge passage on one side of the bowl, and a waterpassage terminating in a jet-orifioe on the opposite side of the bowl, said jet being directed toward the bottom of the bowl.

2. An integral water-closet bowl, comprising a hopper having its sides gradually inclined to a central outlet, a siphon-discharge passage on one side of the bowl, and a downwardly-directed water-passage terminating in a et-orifice on the opposite side of the bowl, said jet-orifice bein below the lowest water-level in the bowl an delivering the jet against the bottom of the bowl, whence it is deflected into the siphon-discharge passage.

3. An integral water-closet bowl, comprising a hopper having its sides gradually inclined to the central outlet, a flushing-rim around the upper edge thereof, a siphon-discharge passage on one side of the bowl, and a downwardly-directed water-passage terminating in a jet-orifice on the o posite side of the bowl, said jet-orifice being below the lowest water-level in the bowl and delivering the jet against the bottom of the bowl whence it is deflected into the siphon-discharge passa e.

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