When an electric heater is employed, the lead in and lead out wires may conveniently extend through this opening 12, instead of the gas pipe connection 16. f.

17 indicates the dry closet container proper, having a suitable bail or handle 18, with the usual removable apertured seat 19, and hinged cover 20 therefor.

Theupper rear peripheral wall of this container' is provided with a foul air outlet 21, terminating in a projecting tubular extension or upper coupling pipe member 22, which is so spaced vertically, relatively to the lower conduit pipe connection 13, that these upper and lower pipes aline in axial registration, respectively, with the coupling member 5 and aperture 4 of the base standard, when the parts are assembled.

vrlhe foul air outlet 21 ispreferably encompassed by a shield element 23, which is in the nature of a curved platespaced interiorly of the rear peripheral wall of the container, and forming a pocket terminating substantially above the foul air outlet,

with an penlng 24: intermediate of thel outlet proper and the extreme upper portion of the container. This shield not only increases the working capacity of the container, which may now be filled above the position of the foul air outlet, but also the arrangement is such that a suctional down draft is provided for, as ,will later appear, functioning to draw d own and out, more effectively, any foul air or. gases arising and accumulating above the outlet opening,

and finally escaping around the seat closure.

to the interior of the room, which would be manifestly objectionable.

vThe bottom of the container 17 rests above and closes the open top of the pan 10, being guided, centered, and supported in place by means of the offset detachably attaching projections 25, as clearly shown.

The projecting end of the base standard coupling pipe member 5 is outwardly flanged, as at 26, and is engaged by the inturned flange 27 of an enlarged coupling union 28 rotatably mounted on the pipe 5, and adapted to receive the projecting end of the container coupling pipe member 22.

The latter pipe member 22 is provided, on each side thereof, with an outwardly depressed lug 29, being of lengths approximately about one-fourth of its circumference, and these lugs 29 are disposedin the path of a spiral, functioning with a screwthreaded or wedging action in association with complementary internally projecting pins or lugs 30-31 carried by the inner wall face of the coupling member or union 28, as will be clearly understood from the drawings.

' In assembling or installing the closet, the pan 10 is properly positioned, with 'the projecting end of the conduit pipe fitted in or in line with the lower opening 4L of the base standard pipe 1. The container 17 is then simply seated thereo-ver, with the upper pipe coupling members 5 and 22 registering in axial alinement but with their adjacent ends slightly spaced apart, as seen in Fig. 5. Upon the rotation of the union 28 to the left, .in Fig. 5, it will be observed that the engaging .pin 30 thereof will ride up the incline of its spirally associated lug 29, while the opposite pin 31 V'will reversely ride down its complementarylug 29, causing the ends of the coupling members 5 and 22'to be'tightly drawn together, and the whole xture held securely in that position, as seen in Figs. 1,6 and 8. Thus it Vwill be apparentthat an effective coupling' may be speedily made with little or no trouble or effort, while detachment of the container, for emptying and cleaning, may also be facilely accomplished. i

When so set up,.a suitable liquid deodorizer and germicide may be introduced into the container as usual, if desired, and this regardless of whether or not lthe heating feature is utilized at all times, for the improved type of exceedingly effective joinder betweenv the container and the base standard, so that this improved arrangement alone would provide for conveying olf the foul odors by way of the vent pipe.

j When the heater feature is placed in operation, however, it will not only tend to evaporate and reduce the contents of the container, while driving out therefrom foul odors and destroying' the germ life thereof, but also a more intense draft will be created through the vent pipe, by way of the upper coupling makes au roo lower conduit pipe 13 conununicating with the hollow base standard, providing a positive suctional force through the upper coupling 5-22, and hence a down draft over the-shield 23, thus sucking out all foul odors and gases from the interior of the container. Obviously the lower damper 6 will control the degree of this draft, while the upper damper 7 will likewise control the suctional force through the upper coupling, when the dampers are properly adjusted.

With the foregoing complete disclosure, it is believed that any further description would only .be superfluous and prolix, and while it will be understood that I do not make any broad claims to the detachable coupling up of a dry closet container with a vent pipe generally, at the same time, I do not limit myself to the exact details as set forth, excepting as come within the purview of the ensuing claims, when viewed in the light of the specification and contemplating a fair range of equivalents. y

What I do claim, as new and practicable, is

1. In dry closet fixtures, the combination with a hollow base standard forming the bottom section of a vent conduit; of a container and suitable apertured seat therefor, said container having a foul air outlet through its upper peripheral wall; tubular coupling means extending from said foul air outlet to the upper portion of said base standard, providing a vent passage therebetween; and heating means for said container, functioning to evaporate the contents thereof, substantially as described.`
