3 Claims.

This invention is a water closet having means to prevent splashing caused by the dropping of feces thereinto. Summarized briefly, the invention is a water closet provided with a cross member immediately below the water level thereof, onto which the feces will fall, said member break ing the fall before a splash occurs.

The following are some of the moreimportant objects.

First, to safeguard against splashing regardless of the location in the bowl at which the feces drop;

Second, to insure that no part of the feces will lodge against the bowl surface above the water line;

Third, to incorporate the cross member in the bowl without substantial modification or redesign of said bowl;

Fourth, to merge the cross member into the bowl surface in such a way as to eliminate crevices or sharp joints and insure the passage of flushing water over the feces-contacting surfaces of the cross member;

Fifth, to arrange the flush water passage of the bowl for directing streams of said water directly against the cross member through substantially its full length;

Sixth, to provide for minimum interference with operations conducted in clearing obstructions from the trap; and,

Seventh, to form the feces-contacting surfaces of the cross member in such a way as to prevent the feces from lodging thereon.

Other objects will appear from the following description, the claims appended thereto, and

from the annexed drawings, in which like reference characters designate like parts throughout the several views, and wherein:

Figure 1 is a top plan view;

Figure 2 is a sectional view on line 2-2 of Figure 1;

Figure 3 is an enlarged sectional view taken substantially on line 3-3 of Figure 2;

Figure 4 is an enlarged sectional view taken substantially on line 4-4 of Figure 3; and

Figure 5 is a view similar to Figure 2, showing a modified form.

The water closet constituting the present invention has been generally designated ID in Figures 1-4. It includes a bowl [2 provided with an outlet l4 opening into a trap having a riser passage l6 extending upwardly from the bowl outlet 14 to a reverse bend portion l8 merging into a descending passage 20. The water level L is, as usual, coplanar with the upper end of the riser passage. The bowl tapers toward its lower end, the wall thereof being inclined at a minimum from the vertical. This is to insure, to the maximum extent, that the feces will drop into the water directly without "first striking the wall, whether a child or an adult is using the water closet. Some water closets of which I have knowledge are so designed as to cause the feces to first strike the wall, this being, perhaps, intentional on the part of the designer to minimize splashing. In such instances, particles of the feces often adhere to the wall above the water line, and do not wash off even after repeated flushings. Other water closets are designed to cause the feces to drop directly into the water, but this has the disadvantage of causing splashmg.

I provide an anti-"splash means that eliminates both of said undesirable characteristics of ordinary water closet design. Said means .has been designated 22, and comprises a cross member which, in Figures 1-4, extends diametrically and horizontally across the bowl intermediate the upper and lower ends thereof, said cross member extending from front to rear of the bowl as shown in Figure 2. The cross member 22 is integral or otherwise made rigid at its ends with the front and back surfaces of the bowl and extends in parallelism with, but slightly below, the water level.

The cross member 22, as shown in Figure 3, has

upwardly facing, feces-contacting surfaces 24 extending through substantially its full length. These surfaces are inclined transversely of the cross member, sloping downwardly and outwardly in opposite directions from the longitudinal center line of the cross member. The arrangement insures against the feces lodging upon the surfaces 24, and results in their slipping off the cross member from either side thereof, after having had their fall broken by the cross member in a manner that safeguards against splashing.

At their opposite ends, the surfaces 24 merge into longitudinally curved, upwardly tapering ribs 26. A pair of said ribs is provided at each end of the cross member, the ribs of a pair being spaced apart transversely of the cross member to define a flush water channel 28 therebetween which extends downwardly to terminate at the adjacent end of the longitudinally and centrally extending raised portion of the cross member defined by the sloped surfaces 24 thereof. At their upper ends the ribs and channels merge into the inner surface of the bowl Wall.

At the opposite ends of the cross member, the

the bowl wall, and the sides of said member have similarly rounded junctures 32 with said wall. This eliminates crevices and facilitates cleaning of the bowl.

An inlet 34 from a fiush tank, not shown, communicates with a peripheral conduit 36 at the upper end of the bowl. A conventional, downwardly extending flush water passage 38 communicates between conduit 36 and the lower end of the bowl. Outlet openings 39 are also provided, to cause flush water to flow downwardly over the bowl surface.

I prefer to provide, additionally, an enlargement 4!! on the upper end of the bowl having a chamber 12 opening from the conduit 36. The chamber is in communication with a series of outlet ports 44 angularly related to one another as shown in Figure 2, said series being aligned with the cross member longitudinally of said member. The arrangement causes narrow streams to strike the cross member at locations spaced along its length, thereby to insure the proper cleaning of adhering feces particles therefrom.

The proper cleaning of the cross member is further insured by the channels 28. Water flowing downwardly over the bowl wall will be guided thereby onto the cross member, and will flow toward the midlength location of the cross member, before dropping off the sloped surfaces 25.

In Figure 5, the water closet 46 is like that of Figures 14 with the exception of the cross member 48 thereof. This has one end integrally secured to the front bowl wall as in the first form of the invention, but has its other end spaced from the bowl wall. In this form of the invention, an even greater amount of flush water could be guided into the channel at the anchored end of the cross member.

It is believed apparent that the? invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claims.

What is claimed is: p

1. A water closet comprising a bowl having an outlet in the bottom thereof; and a cross member extending longitudinally from the front toward the back of said bowl and spaced from the sides of said bowl, said cross member being adjacent to and spaced above said outlet.

2. A water closet comprising a bowl having an outlet in the bottom thereof; and a cross member extending longitudinally from the front to the back of said bowl and having its ends secured to the front and back portions of said bowl, each of the ends of said cross member terminating in a pair of spaced ribs to define a flush water channel, said cross member being adjacent to and spaced above said outlet.

3. A water closet comprising a bowl; and a cross member extending thereacross, said bowl having flush water outlet ports opening into the bowl above the cross member and arranged in a series aligned with the cross member longitudinally thereof, to direct streams of flush water against the cross member at locations spaced longitudinally of the cross member.
