SPECIFICATION forming part of Letters Patent No. 759,078, dated May 3, 1904.

Application filed March 19,1903- To 00% whom it may concern.-

Be it known that I, DAvID CRAIG, a citizen of the United States,and a resident of Melrose, in the county of M iddleseX and State of Massachusetts, have invented new and useful Improvements in Urinals, of' which the following is a specification.

My invention relates to urinals; and its object is to provide an improved urinal capable of eifectively collecting and carrying away the gases which arise from the bowl, of protecting from injury by oxidation or corrosion the waste-pipe fittings or other piping or metalwork below the urinal, and containing other useful features hereinafter pointed out.

Urinals of the class to which my invention relates usually consist of a porcelain bowl, the back of which is flat and adapted to be fixed in position against the wall. It is usual to provide a perforated pipe extending around the edge of the opening of the bowl or urinal, through which the bowl may be flushed at intervals by admitting water to the pipe. Heretofore it has also been usual to provide a vent in the back wall of the bowl, but below the flushing-pipe, communicating with a ventilatting-pipe leading to the exterior of the building for the purpose of carrying away the gases which collect in and arise from the bowl. The location of this ventilation-opening below the flushing-pipe is objectionable, for the reason that the water discharged from the flushing-pipe flows across the opening and closes it, thus interfering with the draft and cutting olf the entrance of the gases into the ventilator for the time being. FuItllGlIllOlG, the water enters the vent and tends to soil it, both by leaving deposits of whatever sediment may be in the water and by constantly wetting it, so that it is in condition to accumulate dust and dirt, which adhere to the wet surface and not only disfigure the urinal, but necessitate fre quent cleaning. Another defect in the present construction of urinals is that the metal piping, coupling, and other fittings below the bowl are exposed and unprotected, the result being that moisture flowing or dripping down upon the outside of the bowl reaches the metal fittings and corrodes and oxidizes the same, tending to disfigure and ultimately to destroy Serial No. 148,514. (No model.)

them. Still another defect in the present construction of urinals is the absence of any device to perfectly collect the gases arising from the bowl and to direct them into the ventilator-opening in such manner as to insure their removal. Without such provision only part of the gases will find their way into the ventilating-opening and the rest will pass off into the air of the room. To overcome these objectionable features, I have provided the bowl of my improved urinal with a w 11tilating-outlet located above the water-outlet of the flushin g apparatus and outside of the path of How of the water, so that the passage of the water down the back of the bowl in no way interferes with the draft through the ventilating-opening nor tends to foul the same. I have also provided a skirt or shield. depending from the bowl to conceal and protect the piping, &c., below the bowl from drippings descending the outside of the bowl. I have also provided a hood or canopy at the top of the urinal and extending substantially over the bowl to collect the rising gases and direct them into the ventilatingopening, thus insuring more perfect ventilation than has heretofore been secured.

In the accompanying drawings, Figure .1 illust "ates a central vertical section of a urinal embodying my invention, and Fig. .2 illustrates a front elevation of a urinal embodying my invention.

Like parts are indicated by like letters of reference in both figures.

A represents the bowl of the urinal, of which the back wall (4 is made flat, so as to be parallel with the wallagainst which the urinal is placed. (he top edge of the bowl is bordered, as usual, by a pipe 11/, which is perforated at intervals throughout its length upon the inner or lower side. The pipe (1/ communicates with a port 0?, which is connected by a pipe (not shown) with a supply of water, and this port (0 opens into a pipechamber of, extending vertically behind the wall (0 of bowl A and inclosing the pipe (not shown) that is connected with-port e A series of separated annular rims a are also formed upon the under side of the bowl A, constituting one member of a coupling, the other member of which is not shown, but

may be on the end of a metal pipe leading, as usual, through a siphon to a sewer.

Integral with the bowl A and upon the bottom thereof is a depending skirt or apron B, which extends around annular rims a and the end of the waste-pipe and its couplings. The moisture flowing down the outside of bowl A is deflected and prevented from reaching the coupling or the metal piping located below the urinal. Moreover, the pipe connections below the bowl, which are unsightly unless costly and finely finished, are hidden from view, and therefore do not need to be as ornamental as heretofore required. The skirt or apron B is open at the bottom to permit free access to the pipe connections for the purpose of repair and to permit easy coupling of the waste-pipe. Skirt B extends around in front of the pipe-fittings, but is open at the back, the ends abutting against the wall.

At the top of wall a is provided a short extension (0*, and through this extension is provided the ventilating-outlet C above the flushing-outlet a and removed from the path of the flow of water. As will now be obvious, its location above the pipe 0 makes it impossible for the water discharged from said pipe to interfere in any way with the draft through said outlet, and also makes it impossible for deposits of foul matter to be left in said outlet by the water crossing it as heretofore, and by keeping it dry lessens the accumulation of dust and dirt therein. Furthermore, the outlet 0 being located above the flushing-inlet instead of in the rear wall of the bowl may be of any size and is not limited to the size of the rear wall of the bowl.

A hood 0 at the top of the urinal overhangs the bowl A, and like an inverted funnel tends to collect and gather in the gases arising from the bowl. This hood is preferably formed integral with the extension (4*,

and extends substantially over the bowl, providing, in effect, an enlarged opening of the ventilating-outlet, the mouth of which is thus carried forward to a point directly over the bowl.

hat I claim is- 1. As a new article of manufacture an integral urinal comprising a bowl made with an outlet through its bottom; a depending skirt surrounding and shielding said outlet; said skirt being open at the bottom, a hood at the top of and overhanging the bowl, and a ventilating-outlet leading backward under the hood and through the rear wall of the article.

2. As a new article of manufacture an integral urinal comprising a bowl made with an outlet through its bottom; a depending skirt surrounding and shielding said outlet, said skirt being open at the bottom; a hood at the top of and overhanging the bowl, a ventilating-outlet leading backward under the hood and through the rearwall of the article; a water-inlet port under the ventilating-outlet and leading backward through the rear wall of the article, and a perforated pipe around the periphery of the bowl communicating with said port.

3. The new article of manufacture above described made up of the bowl A; ventilatingoutlet 0 through the rear wall of the article; the hood 0 above outletC and projecting over the bowl A; the port (0 opening downwardly into the pipe-chamber 0/ behind the bowl A; and pipe-chamber (6 the pipe a communicating with port (0 and the depending skirt B open at the bottom.
