CLOSET.

Application filed February 13, 1928. 7 Serial No. 253,823.. r

This invention pertains towaterclosct construction particularly adapted for. the

cleansing of receptacles such as bed pansal-v though having its ordinary utility. I am aware that a number of water closets adapted for the special service of cleansing sanitary receptacles such as bed pans have been devised and used but all of'thein either involve difficulties in their manufacture or are expensive or do not perform or'admit of performing theoperation of cleansing the bed pan or the like properly or thoroughly or are so constructed that the pan, when placed in position in the closet for cleansin may tilt'under the action of the jet of cleansing water and cause the water and contents to be thrown out beyond the confines of the closet; In someof the types of closets heretofore constructed for t is purpose, thearrangement has beensuch that the bed pan, wheninverted within the bowl of the closet, had its spout directed toward'the front of the closet, objectionable for obvious reasons.

It is therefore the primary object of my invention to provide arcloset of the character described which will be comparatively simple and. cheap to manufacture and soarranged "arid constructed that a bed pan with its spout directed toward the rearof the closet when in inverted position maybe securely, and lirinly positioned within the closet bowl below lts rim and cleansed bya single jet of water prIeferably supplied through a control valve independent of the bowl or hopper flushing .valve.

Many other objects including the uses and advantages of my invention will be orshould become apparent after readingthe following description and claims and-after viewing the drawing in which: r

'Fig. 11 is a sectional. elevation taken from front to rearthrough a siphon jet vclose'tembodying my invention showing a bed pan placed therein. I Fig. 2 is a top plan view ofthe saline, and,

Fig. 3 is a section taken along the line 3 of Fig. 1 with the closet seat raised;

Thecloset bowl or hopper generally designated 2 isformed in onepiece from pottery or vitreous material and is provided with a siphoning channel 3 and orifice 4i through which a st of water from the ordinary flushing source is supplied to start and maintain the siphonic action and with a hollow rim 5 received within the rim.

the. flushing source in'the usual manner and for thefwell known purposes. A closet seat 7 1s plvotally secured to the bowl by'means of hinges 8 in the usual manner.

The rim 5, as will be noted most clearly from Fig. 2 is Wider across the front of the hopper or bowl than it is across the back so that a bed pan turned upside down with the spout toward the rear of the hopper may be The front portion of the rim 5 centrally ofthe bowl is depressed or projected forwardly asshown at 5. in order to facilitate insertion of a hand to grasp'the rear ofthe pan. The interior side walls ofthebowl below the rim converge sharply inwardly to provide shoulders, or shelves 9 which may at the front merge into one another while the exterior sidewalls are contoured to convex shape. asbest illustrated in Fig 3, leaving an air chamber therebetween on each sidei lighter product and permit the exterior side to be given a pleasing curvature. The shoul- I The air chambers provide a] dersor'shelves 9 are substantially horizontal 'transversely of the closet although they "in eline slightly toward the rear terminating" Over half way from the front to 'the rear so as to provide a proper supportingsu-rface for. a bedpan 10. r The shoulders '9 are of such depth below, the top of the rim 5 that the average bed pan will fall entirely below the top of the rim 'whenjseated thereon while. between them a channel 11, toward whichthe upper surfaces of the shoulders' 9, are slightly inelined, drains toward the back of the bowl orhopper. Substantially centrally between the shoulders or shelves 9 and substantially centrally of the length of the channel 11 is a flushing jet 12 to which water is supplied through a pipe and valve 13 and 14- connected to any convenient-source of water supply.

The bowl rnn 1s:madev narrower than "111 'prior constructions which makes the article more sanitary and easier to manufacture. Furthermore, in order not to permitv the .un-

'necessaryexpenditure of water at the front and forward, portions of the bowl when it in the rim is gradually choked or narrowed down, in cross-sectional area from the rear to the front of the bowl as will be apparent from the drawings. This permits the rim itself to be gradually narrowed or reducedin thickness from the rear to the front of the bowl as will also be apparent from the draw:

is flushed, the water channel or water passage ings, partici'ilarly Fig. 2. The arrangement of the water channel not only saves water but serves to reduce the tendency of the water to surge upwardly in the bowl at the front thereof duringfiushing and the reduced thickness or the rim or what may be termed the reduced over-hang of the rim over the bowl, makes the fixture more sanitary than it would otherwise be. ater for flushing the bowl is, of course, supplied to the rear thereof in the usual manner;

In operation when the bed pan has been disposed in inverted position as shown in the drawing with its spout toward the rear, the operator turns on the water leading; to the jet 12 which thoroughly flushes the pan whereupon the pan may be lSlllOVSCl', or,- if desired, the closet itself may be flushed in the usual l111Ill1 3DlJBfOIC the pan isren'ioved.

By reason of the long and broad bearing surface of the shoulders or shelves 9, there is no danger that the pan will tip and permit the spray from the jet 12 to discharge the contents outside of the closet but instead, the pan will remain steady in its position while being flushed. By arranging the bowl of such shape that the bed pan can only be received therein when its spout is in a rearwardly directed position, the contents can only be discharged to their proper place within the hopper. The sir 'le ct is ei'ficient and effective a d certainly of tar more simple and cheap construction than could be obtained with two or more jets.

, While I have described and illustrated what is at present a preferred tot-mot niy invention, it will be obvious that variations and changes I be made therein without departing f in the spirit of the invention or the scope of the appended claims.

I claim i 1. A water closet hopper con'iprising a bowl having a flush rin'i extending perimetrically thereabout and wider across the front of the hopper tha i across the back whei'reby a bed pan turned upside down with the spout toward the rear of the hopper may be received within the rim, a shell on the interior ol the bowl provided with asubstantially flat horizontal shelf suril ace substantially below said riin extending: from the i rontnlong each side over half oi the distance toward the rear thereof wherel'iya bed pan may be :ulpportcd in inverted position within the hopper and below the rim thereof, said shell being iinperforate and together with the bottom of the bowl providing a downwardly and backwardhaving a flush riin extending perimetrically.

thereaboutand wider across the front of the hopper than across the back whereby a bed pan turned upside down with the spout toward the rear of the hopper may be received within the inn, a central front portion of the rim having a "forwardly depressed portion whereby access to said bed pan for grasping it may be had, a shell on the interior of the bowl provided with a substantially flat hori zontal shelf surface substantially below said rim extending iiroin the front along each side over hall of the distance toward the rear thereof whereby a bed pan may be supported in inverted position within the hopper and below the rim thereof, said shelf being ini- .iertlorate and together with the bottom of the bowl providing a downy-validly and baclwardly inclined. channel between the portions oi the shelf along the sides the bowl, and a jet orifice through the bottom Gifhiltiltl channel substantially central of the length and width thereo'ii'. I

3. A water closet hopper comprising a bowl of vitreous material having a flush rim ex ten inp; perimetrically thereubout, said riin having an internal water chani'ielextending cherethrough and about the bow said channel being; substantially closed except ttor'a plurality of downwardlv directedjet orifices and gradually narrowing in cross sectional area from the rear of the bowl around both sides to the front tllclGO'f, there being a wa ter inlet to the channel at he rear of the bowl. j V a l. A water closet hopper comprising a bowl of vitreous inate al having a flush run on tending perin'iet thereabout, said rim being narroweddown from the rear oi the bowl toward the front thereof and l'iaving an internalv .vater channel cr-ztinc'nn i throu o, and about d bowl, Slltl' being: closed except for a plurality of deal wardly directed jet orifices and. said chan nel gradually narrowing in cr sectional area from the rear of the bowl "ound both sides to the front thereof, there being a tor inlet to the channel to the rearot the bowl.
