11 Claims.A
Our invention relates to a type of bowl in which the latter may be pivotably mounted in a manner such that While normally disposed in a concealed and out-of-the-way position, the bowl can easily 5 be withdrawn therefrom and brought to an operative position whenever desired, and also be capable of functioning satisfactorily on relatively small amounts of flushing water.
An important object of our present invention lies in providing for a folding type of closet bowl construction of the general character hereinafter described wherein, for example, the bowl is retainable in a folded position within a cabinet or enclosure and upon actuation of a door or panel or the likeforming a part of the said enclosure, the bowl is subsequently unfolded vand rendered operative. Conversely, by closing the door or suitably replacing the actuating panel of the enclosing cabinet or structure, the bowl can be made to recede, occupying the space provided for by the enclosure and thus render the latter member concealable from view, as for example, when installed in the compartment or bed room of passenger railway cars, in small apartments or the like.
The details of the novel features applying to the actuating mechanism above referred to are covered in a copending patent application, Serial No. 237,434, filed October 28, 1938, now matured into Patent 2,188,562, granted January 30, 1940.
It is a further important object of our invention to provide a construction in which the closet bowl when withdrawn from the enclosing cabinet or recess and placed in an operative position has its receiving portion automatically water sealed in a manner hereinafter described, and thereby serves to increasethe effectiveness of the subsequent fiushing therefrom, even considering its installation upon railway cars and the like where the available water supply will necessarily be limited.
Another object lies in providing in a closet bowl for a hollow sleeve or trunnion type of supporting means whereby the relatively fragile earthenware member, such as the bowl itself, is securely supported upon the said trunnion member and is suitably reinforced by the supporting means so as to minimize the dangers from shock, vibration and the like, with its otherwise deleterious effect upon the ware.
Another object is to provide in this type of device for adjustable stop means for-accurately and conveniently leveling the bowl in its operative position thereby conveniently allowing for any irregularities encountered in the initial installation.
Another important object lies in the provision of a construction in which the bowl supporting trunnion member serves -as a leak-proof mount during the course of operation and also provides unitarily for both the inlet supply to the xture as well as for the discharge therefrom, in addition to the important function of serving as a substantial shut-off for the inlet supply at a predetermined pivotal position of the closet bowl.
Another object lies in providing for a means of discharge from the fixture and into the trunnion member whereby a rapid and effective siphonic ushing action will be obtained incidental to the actual discharge, thereby furthering the sanitary functioning of the fixture.
Another object lies in the provision for a base or support for the fixture whereby the latter, as a complete unit, may be assembled and applied to the installation conveniently, including the necessary valves, actuating mechanism and base member for the mounting thereof asa unit, thus enabling the manufacturer to ship the fixture as an assembled unit with the flushing mechanism properly adjusted, based upon factory tests.
Other objects and advantages will become more readily apparent upon proceeding with the following specification in connection with the drawings, in which Fig. 1 is a side exterior view slightly in plan perspective of a folding closet bowl embodying our invention and which bowl in this view is shown inthe lowered and operative position.
Fig. 2 is a front exterior perspective view partly in plan perspective in which the closet bowl is shown in its folded and inoperative position.
Fig. 3 is a plan exterior view of the closet bowl and base assembly showing the space-saving manner in which the closet bowl is preferably positioned with relation to its mounting base so as to allow for sufficient space for the necessary control xtures without requiring extra space provisions therefor within the cabinet or enclosure.
Fig'. 4 is a rear, partly exterior view showing a preferred method in which the discharge return bend is applied to the xture support, and showing in fragmentary section the manner in which the journally mounted trunnion or sleeve member is position with relation respectively to the inlet supply, the discharge outlet and the actuating mechanism for revolvably moving the trunmon.
Fig. 5 is a side exterior view showing in solid lines the closet bowl in its operative and lowered position and in dotted lines indicating the inoperative and folded position.
Fig. 6 isa magnified fragmentary sectional View taken on the line 6--6 of Fig. 2, showing principally the trunnion member inlet and discharge passages and the end mounting thereof with rela tion to the actuating mechanism.
Fig. 7 is a fragmentary sectional View of the dual flushing and bowl sealing valve serving the joint purpose for accomplishing the discharge from the inlet, past the stop valve, through the dual valve respectively and thence into the passages dening the jet flush and the rim flush of "the ilxture.
Similar reference characters refer to similar parts throughout the various figures.
Referring to Fig. 1, the folding closet bowl generally designated as I is illustrated as being provided at its base portion with a conduit 2 having connection with a suitable source of water supply (not shown) and with the direction of the `water ilow being taken as indicated by the arrow. Preferably, but not necessarily required, in connection with the control of such water supply, a stop valve 3 is provided so that in the event it is necessary to make adjustments, repairs or inspection of the fixture, the stop valve may be used to shut oil' the water supply to the fixture. The latter valve is attached by means of a suitable pipe connection 4 to the lower chamber of the trunnion base 5. The latter member is preferably provided with an extension 8 of the said hollow chamber which, by means of the bolting member 1, serves to hold the latter in xed position with relation to the floor plate 8.
As previously mentioned, the closet bowl is pivotally mounted upon a rotatable hollow trunnion and with this in mind reference is made to Fig. 6 in which the said hollow chamber of the trunnion base 5 is shown as being connected with the inlet 4. The trunnion base member 5 is provided with a port or passage 9 through which the water passes from the hollow chamber and thence leads upwardly into the housing III. The latter housing interiorlyis provided with a cylindrically machined bearing portion I I within which the hollow trunnion shaft I2 is journaled for limited rotative movement. The said trunnion shaft I2 is made with a cylindrically formed longitudinally extending passage I3 and on its lower periphery has the circular aperture I4. In the lowered and operative position of the closet bowl, the aperture I4 coincides with the similarly shaped passage 9 thereby serving as a port through which the water enters the interior of the hollow trunnion shaft I2. When the bowl is in its inoperative and upwardly folded position, the aperture I4 will have been moved in a clockwise direction (viewed from end of trunnion), and accordingly the walls of the shaft I2 serve to substantially shut off the connection between the passage 9 and the trunnion passage I3, thus enabling the trunnion to function as a sleeve valve. The bearing portion II is interrupted so as to provide for an enlarged recess I5 serving as a stuiilng box for the packing I6 in which cooperating therewith is a bolted gland I1 exerting the desired compression upon the stuffing box packing by means of the bolts I8. Thus a journaled leak-proof bearing for one end of the trunnion shaft is provided.
On its upper portion, the housing III is conveniently provided with an apertured lug or vear I9 having for its object a purpose hereinafter described in greater detail in connection with the dual valve ushing means. Continuing with a detailed description of the bowl supporting trunnion, beyond the stufllng bex the hollow shaft I2 is suitably enlarged as at 28 thereby forming the end chamber` 2| within which the inlet supply flow is directed upwardly into an outlet'22. The latter outlet is connected with the flexible tubing 23 leading therefrom by means of the threads 24 and the locknut 25 to form a joint as indicated.
As more clearly shown in Fig. 1, the flexible tubing 23 communicates with the dual control valve, generally designated 26, for the flushing of the bowl and afterwards sealing the same, and which is connected thereto by means of the union ring 21. The dual valve 26 is provided with the inlet port 28 leading to the successively arranged and interconnected chambers 28 and 3l respectively. The dual valve, having the mounting pad 30, is rigidly attached to the side of the bow1 by means of the bolts 32. Obviously, depending upon the nature of the installation, the attachment of the dual valve may be onthe right or left side with the bowl selected for the attachment pad accordingly.
At this stage of the description it is desirable, in general, to understand the path of the inlet water within the dual valve on its way to the bowl, and therefore reference is now made to Fig. 7, showing the internal construction of the valve proper. The casing of the dual valve is divided into two chambers, as indicated, both of which are interconnected, as previously mentioned, by means of the port 33, forming the wall connection between the two in view of the partition wall 34. At the lower portion of the casing, the respective hollow chambers 35 and 38 are thereby provided having outlet ports 31 and 38 respectively, each leading to the inlet manifold of the bowl I. Of course, with the valves in the closed position, as illustrated, these lower valve chambers are devoid of any water passing from the inlet supply passage 28 and until each valve is actuated, as hereinafter described, the bowl likewise receives no water through the passages 31 and 38. The bowl is provided with the conventional manifold 40 in its inlet supply chamber which is not shown in detail but which is designated diagrammatically in Fig. 9. It suffices to say that so far as this invention is concerned, the bowl manifold has passages leading respectively to the rim flush 39 and to the jet flush 4I within the bowl I. The detailed manner of accomplishing the successive operations oi the dual valve 26 in its application to the flushing and sealing of the bowl, will be described at length later in the specification.
'I'hus far the description of the hollow trunnion shaft mounting has been concerned only with that function having to do with the inlet supply ofvwater to the closet bowl through the respective passages and valves to the manifoldy leading to respective passages to the bowl rim flush, jet and seal. But, as mentioned, the trunnion serves also to handle the outlet or discharge from the bowl.
Therefore, reverting again to Fig. 6, and continuing with the description of the hollow trunnion shaft, the enlarged portion of the hollow trunnion shaft I2, as previously designated at 20, is provided with an enlarged extension 42 which is separated from the previously described fresh water inlet chamber 2| by means of a wall or partition 43 and also having a substantially round port 44 extending transversely thereto; The said port 44 thereby forms a side passage in to the hollow trunnion for a connection by means of a bolted flange 45 to a return bend48, the latter member'being attached thereto by means of the integral bolted flange 41 and the bolts 48 (see Fig. 5). It will be noted further that the return bend 48 is of substantially U-form, as shown more clearly in Fig. 5, and extends upwardly and then forwardly so as to connect with a similar flange 49 and the bolts 50 andthe nuts 5|. The return bend 48 beyond the flange 49 is provided with an annularlyformed extension or lip 52 which abuts against the rearwardly extending discharge outlet of the closet bowl I in a conventional tongue-and-groove connection, as indicated at 53. The discharge outlet portion of the bowl I is provided with a complementary companion flange 54 whereby the bolts 50 may be held rigidly by the joint means provided by the nuts 55 and the cap screw 58 thus forming a liquid-tight joint at 53. The connection currently described in cooperation with the return bend 46 provides for the necessary discharge of the contents from the interior of the bowl proper passing into the return bend which communicates with the side opening 44 of the trunnion shaft and then flowing into the interior passage 51 of the enlarged portion 42 of the bowl supporting trunnion shaft.
At this stage, the flow of the bowl contents is facilitated perceptibly by the arrangement of a compound turn simulating siphonic flow through a closet trap and is accomplished by the relation of the longitudinally extending discharge passage 51 with the discharge inlet port 44, A flow wiping action is obtained Within the trunnion passage particularly when the flow strikes the fillet I2a after being deflected slightly upwardly by passing over the arcuately positioned ridge I2b, and then passing into the downwardly extending passage 18 connected with the passage 53 of the plate 8.
As to the external mounting of the enlarged end of the hollow trunnion shaft I2, in order to accommodate the necessary discharge capacity, the said trunnion shaft is suitably enlarged at its peripheral bearing 58 within the opposite trunnion journaling member 59. It is further provided with a cylindrically formed, preferably machined bearing which is rendered substantially leak-proof by the stuffing box packing 6I compressed within the recess 52 by means of the gland member S3 acting in cooperation with the stuffing box nut 54. In order to further assure of a liquid-tight seal at the transversely extending end portion l2c of the bearing 58, a gasket 55 is preferably interposed between the said end face E20 of the trunnion bearing and the inner end face of the enlarged portion trunnion journaling member 59. Projecting preferably integrally from the end face E2G, an actuating shaft 55 is provided for the transmission of the desired rotation to the hollow trunnion shaft i2. To accomplish such actuation, a bevel gear 51 is mounted thereon and pinned in non-rotatable relation by means of the lockwasher S8 and the respective locknuts $9 and l, meshing with a similar bevel gear 1I suitably mounted, as a t 12, upon the extension 13 of the trunnion bearing 59 and held non-rotatably to the shaft 'i5 by means of the pin 68. An actuating hub member 14 is non-rotatably mounted upon the journaled rod l5, the said actuating hub having a lever extension i8 which is suitable for attachment to a lever and hinged connection, as at 1i, for such actuation means as may be necessary to rotate the respective bevel gears and in consequence thereof to rotate the hollow trunnion shaft I2 in its reduced bearings 68 and I I respectively.
Since the closet bowl I is fixedly mounted upon the trunnion shaft, as previously referred to, by means of a side outlet connection with the return bend 46 and the bracing support, as hereinafter described, whatever rotation of the trunnion occurs will likewise cause the said closet bowl to be moved arcuately either upwardly or downwardly, depending upon its previous position and the direction of rotation of the actuating shaft 15. A disclosure setting forth a preferred method of accomplishing the actuation of this type of a closet bowl is covered by our previously referred to co-pending patent application.
'Ihe lower peripheral portion of the enlarged end 42 of the trunnion member I2 being provided with the downwardly extending aperture 18, con nects with the passage 19 within the trunnion member 59. The latter member is mounted upon the oor or base plate 8 and is attached thereto by means of the flange member 8|, compressing the gasket 82 to form a joint and leading into the discharge passage 83 of the floor plate 8 which discharge passage may lead to such means for sewage disposal as may be provided. The latter member is suitably formed with the hollow pan-like portion 84 so that when, as indicated in Fig. 5, the closet bowl is placed in a folded position, there may be sufficient clearance so that the return bend 46 may be accommodated in the said position.
It has not been deemed necessary that the internal structural details of the closet bowl should be shown or described herein because its particular functioning with relation to the present invention is not indispensable, and it is suicient to say that the closet bowl herein referred -to has the usual inner manifold passages leading respectively to the bowl rim flush and the jet discharge. Points of novelty reside in certain phases of the internal construction which are being covered in a separate patent application being currently filed and identified as Serial No. 219,504, filed July 16, 1938.
Referring n'ow to Fig. l, in order that the bowl in its lowered and operative position, as shown, may be conveniently and accurately positioned in a level plane with relation to the usual water seal, the trunnion journaling member 59 is provided preferably with an integral lug 85 and an adjust-v ing screw 56 with threads 81a whereby the trunnion member may be adjustably rotated to a predetermined desired position with the screw serving as an adjustable stop therefor shouldering as at 31, the latter member being more clearly shown in Fig. 2,
Continuing with Fig. 2, in order to support properly the somewhatsubstant'al overhang of the closet bowl, it is preferable that the bowl i should be provided with a transversely extending integral lug v8f3 provided with an aperture to serve as anchoring means for the bolt 89, the latter member being attached to the integral lug 9I of the enlarged portion 52 ofthe trunnion l2 using the nuts 92 for maintaining the supporting bolt 89 rigidly in position.
Reference has been made previously herein to the fact that an important element of our invention lies in automatically sealing or filling the closet bowl to a certain predetermined level immediately upon lowering the bowl to its operative position and before actual usage may occur. This is accomplished by a novel arrangement of an actuating mechanism for a flush valve which is employed separately for the purpose and which, as also stated previously, forms a part of the dual valve 26, the other portion of which functions as the flush valve. Therefore, reverting now to Fig. 7, a significant part of our invention resides in the means taken not only to flush the closet bowl in its lowered and operative position but also to automatically provide for the said water seal of a predetermined amount and depth immediately upon having the bowl lowered to its operative position.
The internal mechanism of the dual valve is ofl the type known as the non-hold-open and which, as further described, operates to flush and to seal the bowl by tilting the actuating stem thereof to one side. As will be hereinafter set forth more clearly, when the actuating stern is thus moved, the valve and the stem are lifted by the water pressure acting beneath the peripheral limits of I the valve.
As to a general description of and the manner of functioning the combined flushing and sealing valve 26, the union ring connection 27 attached to the valve is connected to the flexible tubing 23 which, as previously stated, in proper sequence receives the Water supply by means of the hollow trunnion shaft I2 and the trunnion bearing from the inlet conduit 2. 'I'he Water upon entering the inlet passage 28 then passes into the respective upper valve chambers 29 and 3| by means of the inlet bleed holes 93 and 94 respectively in each valve, thus permitting the flushing water to pass into each of the chambers 95 and 96 above the pistons of each of the valves within which the respective springs 91 and 98 are positioned, functioning to place the auxiliary valve members 99 and'll in each of the respective closure members in normally seated position, as shown.
To observe the detailed method of operation of the valves, iirst as to .the bowl flushing method used and later as to the bowl sea-ling and refill method, let it therefore be assumed that the flushing mechanism of the valve is to be operated in which case the pedal member |02 (Fig. 7) is depressed thereby causing .the lever |03 toV be m'oved inwardly and to contact with the head |04 of the horizontal member |05, causing the latter member to move forward against the action of the spring |06.v The said horizontal member is ,journaled within 4the bearing of the gland |01 and the stuiling box |08 and upon such forward movement contacts with the telescoping member |09 tilting the latter to one side so as ,to cause the auxiliary valve member |0| to leave the seat The water already above the auxiliary valve |0| is thereby permitted to descend past the said valve, thereby relieving the pressure of the water also on the main valve ||2 in chamber 3| which is exerted on the surface I3 and also against the cup leather ||4 but which is not relieved. Such release of the pressure in chamber 3| causes the main valve to rise from its seat ||5 and thereby permits the water to pass through the seat opening I|6 vand into the passage 38 'in which, by means of the bowl manifold 40 schematically referred to in Fig. 9, the water flows under line pressure respectively to the bowl rim flush and to the jet flush of the bowl I. Then in accordance with the principle of operation provided by this construction, and regardless of whether or not the pedal is continuously depressed, due .to
the telescoping movement of the auxiliary valve stem within the member |00, the main valve and the auxiliary valve members are lpermitted to return to their respective seats.
'I'he latter action of the auxiliary valve members |0| causes the water pressure to accumulate within the chamber Il and thereby causes the main valve closure member I|2 to descend to its seat, and so the setting of the valves is ready for another cycle of operation. Mention is made at this point that the detailed construction of the again into a lowered and operative position it becomes desirable, for sanitary reasons, that the bowl should immediately be supplied before use with an adequate water seal or refill within the receiving chamber adjacent to the jet 'flush 4|. Accordingly, the latter result is provided preferably by means of .the actuating chain which at one end -thereof is attached to the integral connecting lug i9 mounted upon the upper portion of the trunnion housing |0 and is connected to the bifurcated member by means of .the screw ||8 and Ithe adjustable link H9, while the other end of the chain |20 is attached to the tiltable bifurcated link |2| integrally connected to the actuating member |22 of the refilling valve mechanism. It will therefore become apparent that as the bowl is drawn pivotally downwardly and unfolded upon its trunnion and ultimately assumes a horizontal position, thechain |20 will become taut, being flxedly attached at the end mounted upon the trunnion housing I0, and draws upon the link |2| causing the tilting of the horizontal member |22. Such tilting of the latter member causes the member |04 to be moved axially inwardly sufficiently for its stem portion |05 to contact with the telescoping member |09 (see Fig. 8) and thereby set in motion a cycle of operation of the internal valve mechanism comprising an auxiliary valve member and a main valve member in the same manner as described in connection with the operation of the foot lever |02.
Obviously, in view of the differences in purpose of the respective valves, such as Ithe pedal operated in one case and' the chain operated in the other, there maybe slight changes made in the detailed structure. For example, because the amount of water necessary for supplying the rell and maintaining a water seal in :the closet bowl in its horizontal and operative position will necessarily not require as great a volume of water as in the flushing of the bowl, the main valve in the former may be provided with a lip or shoulder |23 for the purpose of thr'ot-tling or reducing the amount of water flowing past the main valve when the latter is in its open or unseated position.
Referring to the schematic outline of water flow-in Fig. 9, the flow through the passage 38 of the flushing portion of the valve, in relation to .the manifold 40 of the bowl, will preferably pass in a larger proportion to the jet 4|, while for the rell or sealing valve, the larger percentage of flow through the passage 31 will pass through rim flushing apertures collectively designated as 39.
Thus lt will be apparent that we have devised in a relatively simple manner a folding bowl construction capable of being rigidly mounted for pivotal movement, adequately flushed and refilled for further use and capable of being easily accommodated within a recess or cabinet.
While a single preferred embodiment of our invention has been described, it should be readily understood that our invention is capable of a great variety of modifications. Therefore, changes in the construction and in the arrangement of the various parts may be made Without departing from the spirit or the scope of the invention as determined by ,the claims appended hereto.
