3 Claims.

Our invention relates to certain new and useful improvements in a sanitary plumbing device, and more particularly it relates to that type of fixture referred to by those skilled in the art as a urinal stall.

The problem of maintaining proper cleanliness and sanitation in a device of this type has long been recognized as an outstanding one. Particularly where public use is concerned, it is necessary to construct devices so that the possibilities of the existence of an insanitary condition are either avoided or else reduced to the state of a very remote occurrence.

There have been similar devices built in the past designed to avoid insanitary conditions but none of these prior devices by virtue of their construction promoted the use of the device so as to reduce to a minimum the filth and uncleanliness which is ordinarily prevalent.

One of the most important objects of this invention therefore is to provide for a urinal construction which permits the user to maintain a position closer to the urinal, increasing the utility of the forward extension of the basin, and thus promote a higher degree of cleanliness immediately adjacent thereto.

Another object of our invention is to provide for a device which by reason of employing a novel arcuately receding or inwardly tapering and downwardly sloping back surface avoids the usual splashing outwardly and forwardly in a fixture of this type.

A still further object is to provide in a device of this character an improved method for obtaining a thorough flushing or washing of the front basin or the forwardly extending hollow portion or basin of the article.

Another advantage obtained is the reduction in the Weight of the stall by progressively decreasing the cross sectional area of materials above the basin.

Also, the possibilities of warpage and distortion in drying and firing, during the course of manufacture, are reduced to a minimum over previous existing types, due to the increased support provided for the forward extension of the basin.

Other objects and advantages will be readily apparent upon reference to the accompanying drawings, in which Fig. 1 is a front elevation of the urinal stall embodying the features of our invention.

Fig. 2 is a side sectional view taken on the vertical centerline of the article.

Fig. 3 is a top elevation of the device.

Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 2.

In the various views, similar numerals indicate like parts.-

Referring now to the accompanying drawings and specifically to Fig. 2, the urinal stall I is of the upright type having a base or forward extension 2 and a centrally positioned hollow or basin 3 with the customary outlet or drain 4 leading to the waste pipe (not shown). The 10 structure is provided at its upper portion with the inlet water supply openings 5 or 5 depending upon whether the supply is to be made from the top of the fixture or from the rear, the water flowing into the chamber 6 which is provided with the flushing outlets 1 so as to allow for a uniform distribution into the vertically disposed depression and over the preferably inwardly receding arcuately or straight tapering back 8 which extends substantially as shown for the full height of the fixture, curving outwardly as at 9 so as to permit the discharge or flush of Water into the basin 3 and also flush the forwardly extending floor or receptor ll thereof uniformly. In order to accomplish such uniform distribution, the deflecting ribs l2 are so placed with relation to the discharge outlet or drain 4 so that some of the water will be diverted over the forward portion l3 of the floor ll instead of being permitted to take the shortest path to the drain outlet 4. Thus a more thorough flushing is provided than what is ordinarily obtained if the flushing water flowing down the back 8 and curved or inclined surface 9 is allowed to discharge directly into the hollow basin 3 and into the waste outlet or drain 4. Obviously, by such an arrangement the greatest benefit of the uniform water distribution is obtained. In fact, it is well known that in the past constructions, considerable refuse accumulating within the forward portion l3 was not at all affected by the flushing water flowing into the basin resulting in the establishment of a filthy insanitary and disease breeding condition.

It will be noted that the back 8 is partially bounded by vertical side walls l4. As shown more clearly in Fig. 2, the side walls M are provided with front wall surfaces I5 which taper rearwardly from a relatively greater width at the lower portion of the fixture to a substantially narrow width at the top of the fixture, which arrangement enables the user to stand in closer proximity to the fixture, obviously thus promoting greater cleanliness in its use. The forward rearwardly sloping walls or surfaces I5 are arranged to project slightly inward, as indicated,

as at the edges l 6, such edges being in the nature of beads or ribs which extend down to the upper surface 2| of the forward extension 2 and then continue horizontally along the inner edge as at H and join the vertical wall 18 provided likewise with the inwardly extending bead or rib [9 for the prevention of splashing or overflowing at the forward end of the basin 3 and over the surface 2|.

The advantages of the tapered back 8 will be apparent when it is realized that liquids directed against an inwardly receding surface even at close range have decidedly less tendency to splash outwardly upon the floor or upon the user.

It is further evident that the illustrations shown merely exemplify but a single form of the application of our invention and we desire, therefore, to be limited only to the extent of the claims appended hereto.

We claim:

1. A urinal stall having a vertically recessed or hollow body portion, the said hollow body portion merging into a receptor at the bottom thereof, a forwardly extending base portion projecting above the said receptor, both sides of the said hollow body portion having substantially vertical end surfaces, the said sides having rearwardly sloping, forwardly extending walls positioned intermediate to the said hollow body portion and the said forwardly extending base portion defining respectively the forward limits of the said hollow body portion and substantially the maximum side limits of the said forwardly extending base portion, the rear wall of the said hollow body portion sloping inwardly and downwardly above the merging with the said receptor in a direction opposed to the slope of the said forwardly facing walls.

2. A urinal stall comprising a vertically recessed or hollow body portion, the said hollow body portion merging into a hollow receptor at the bottom thereof, a forward extending base portion projecting above the said inclined hollow bottom portion, substantially vertical walls defining the forward limits of said hollow body portion sloping rearwardly toward the upper portion of the stall, flow deflecting means within said hollow bottom portion whereby uniform distribution of the flushing water is obtained there- Within.

3. A urinal stall having a vertically recessed body portion, the said hollow bodyportion merging into a hollow receptor at the bottom thereof, a forward extending base portion projecting above the receptor portion, flow deflecting means therewithin whereby distribution of the flushing water is obtained over the sides and the forward extending portion of the said recessed bottom portion.
