Groeniger, Columbus, Ohio, assignor to John B. Pierce Foundation, New York, N. Y., a corporation of New York , Application April 30, 1936, ‘Serial No. 77,087 3 Claims. This invention relates to defecators i. e., water closets, and more particularly to- defecators com prising a bowl with rim channel flushing means, and a storage tank for a ?ushing liquid, usually 5 water, communicating with the rim-?ow-channel of the bowl. ‘ The present invention has as primary objects the elimination of whistling noises usually at tending the flushing cycle of the above speci?ed types of defecators, the utilization of practically the entire liquid contents of the storage tank during each ?ushing cycle, and the provision for a positive after-?ll of the well of the bowl, sup plied, in a major degree, from the normal liquid 15 contents of the storage tank. Such objects are accomplished by providing suitable air-venting means for the rim-?ow channel of the defecator bowl during the ?ush ing cycle to prevent entrapment of air therein and thus to eliminate syphonic action common ly operative on the supply stream from the stor age tank to effect premature closure of the flush valve. Pursuant to the present invention, embodi~ ments thereof usually comprise a tank for the storage of flushing-liquid, a defecator bowl pro vided with a rim-'flow-channel, a discharge con (Cl. 4--13) Fig. 1» represents a vertical central section through such embodiment. Fig. 2 is a top plan view, hidden channels be ing indicated by dotted lines. ' Fig. 3 represents a vertical section taken on the Fig. 4 represents a horizontal section taken on the line 4_4, Fig. 1. ‘ Referring to the drawings and to the therein illustrated embodiment of this invention, the "\ unitary combination of a defecator bowl ill, a storage tank‘ I l, and an evacuator I2 is of the Wall-hung type and is suitably secured with its substantially planar, Vertical back face 13 against a wall, or equivalent, indicated at M. Such defe-l 15 cator combination discharges laterally through the opening l5 into component piping (not shown) of a waste disposal system. In the particular embodiment, the rim-?ow channel l6 comprehends the upper periphery of 20 the bowl l0 and has branching therefrom at its front a down?ow channel ll terminating in a main flush-jet ori?ce I 8 anteriorly of the well IQ of the bowl. Also, branching from the rim ?ow-channel 16 at an appropriate location is a 25 down?ow conduit 20 terminating in the vortex effecting-jet ori?ce 2!, located advantageously in duit leading from the storage tank to the rim an interior wall of the bowl near the maintained flow-channel and operative to originate and surface level 22a, of the liquid after-?ll 22. 30. maintain a unidirectional flow of flushing liquid around the rim-?ow-channel, an over-?ow chan~ nel within the storage tank, and means alfording communication between the over-?ow-channel and the rim-flow-channel at a location adjacent the termination of the flow-stream in the rim The rim-flow-channel I6 is provided with a plurality ., of jet openings 23 spaced along its underside pe riphery. ' The up-?ow leg 24 of the evacuator ill, at its ' lower end communicates with the well I9 of the include a defecator of the type disclosed in my co bowl I0 at a location opposite post-zriorly the main flush-jet ori?ce I 3, and at its upper end opens into the down-?ow leg‘ 25. Such down ?ow-leg communicates with the lateral discharge pending application for U. S. patent Serial No. opening l5. flow-channel. . Advantageously, embodiments of this invention 4 O 25,475, ?led June '7, 1935, wherein a defecator bowl of the type disclosed in my copending appli cation Serial No. 749,069, ?led October 19, 1934 is novelly combined with an evacuator of the gen— eral nature of that disclosed in my copending ap 45 plication Serial No. 4,620, ?led February 2, 1935. Preferred embodiments incorporate the storage tank integrally with the defecator bowl, and, de— sirably, also integrally with the evacuator. A preferred embodiment of the present inven 50 tion showing a defecator bowl integrally com bined with an evacuator according to the above referred to copending applications, and a storage tank integrally incorporated therewith, is illus 55 trated in the accompanying drawings, in which: v line 3—3, Fig. 1. ‘ The lower portion of the upper wall of the up 40 ?ow leg 24 advantageously forms the rear wall of the bowl, and the upper wall of the down~flow leg 25 advantageously forms the lower wall of the up-flow leg 24. The tank I I for the storage of ?ush liquid rises integrally from the upper portion of the evacua tor l2 posteriorly of the defecator bowl I0 and includes preferably integrally therewith the over ?ow-channel 2G. The bottom wall of the tank I I advantageously forms the top wall of the evacuator I2. The present invention is concerned primarily with the cooperative relationship of the storage tank, and its therewith included over?ow chan 2 2,110,861 the flushing cycle, ?ows backwardly around the nel, to the rim-?ow-channel of the defecator bowl. ' ~ " ‘ ‘ In a defecator embodying a rim--?ow-channel,v for purposes of 'e?ic'iency during the ?ushing cycle, i. e., the elimination of whistling noise, quickness and positiveness of ?ushing action, and utilization of substantially the entire contents of the storage tank, it is desirable to‘ displace all of the air in theFrim?ow channel withnwater 10 at the beginning of the‘ flushing cycle, and to rim-?ow-channel to supply the after-?ll to the well of the bowl. , Whereas, I have * described my invention by reference to speci?c forms ‘thereof, it will be ‘ understood that many changes and modi?cations may be made without departing from the spirit of the invention as set forth in the following claims. . _Iclaim: I ‘ ' ' ' 10 “ displace the water in such rim~flow-channel by .
