SANITARY APPLIANCE SUCH AS WASH BASINS, BIDETS, SINKS, BATHS AND THE LIKE Filed March 30, 1954 2 Sheets-Sheet l 5 Charles HoHel Henri Charms Couehw Patented Oct. 15, 1935 UNITED STATES PATENT OFFICE SANITARY APPLIANCE SUCH AS WASH BASINS, BIDETS, SINKS, BATHS, AND THE LIKE company of France Application March 30, 1934, Serial No. 718,138 In France April 6, 1933 11 Claims.

The object of the present invention is to provide a sanitary appliance such as a wash basin, bidet, sink, bath or the like which fulfils the most rigid requirements of hygiene.

One object of the invention is to ensure the rapid discharge of the polluted water in such an appliance and the consequent removal of the suspended materials.

A further object of the invention is to prevent these suspended materials from fouling in any way the various ducts of the sanitary appliance.

Another object of the invention is to permit all the internal parts and ducts of the appliance to be cleaned easily and completely.

A further object of the invention is to avoid any danger of the mechanical controlling members becoming jammed.

Finally, a still further object of the invention is to avoid the noise which normally accompanies the flow of the water to the waste pipe.

The sanitary appliances which permit the foregoing objects to be attained comprise the features which appear from the following description and from the claims appended to this description.

Sanitary appliances in accordance with the invention are illustrated by way of example in the accompanying drawings, in which:-

Figure 1 is a vertical partial section of a wash basin, the section being taken along the axis of the waste duct and of the overflow duct;

Figure 2 is a horizontal section taken along the line 22 in Figure 1;

Figure 3 is a partial section of another embodiment of the invention;

Figure 4 is a vertical partial section to a larger scale taken along the line 44 in Figure 3;

Figure 5 is a vertical partial section of a bath according to the invention;

Figure 6 is a front view of the lever for operating the rod controlling the valve in the bath shown in Figure 5;

Figure '7 is a vertical partial section to a larger scale taken along the line 'l-'! in Figure 5.

The wash basin illustrated in Figures 1 and 2 comprises an emptying duct 2, an overflow duct 8 and a discharge duct l extended by the waste pipe ID. All these three ducts 8, 2 and l have vertical axes.

The overflow duct 8 which comprises a flow aperture 9 and an upper orifice iii of substantially equal section to that of the overflow duct 8 has a continuous profile comprising no abrupt bends and no projections, the external generating line a. I) being extended by curves b c :1 connected together and having large radii of curvature.

The rigid rod i6 controlling the waste valve 4 '7 TV slides in a square orifice 2| in the plug 20 and in the guide IQ of this plug. This guide thus constitutes a vertical guiding axis for the rigid rod i6 which consequently moves vertically parallel to the vertical displacements of the waste valve 4.

This rigid rod l6 has a shape corresponding to that of the curves b c d connecting the overflow duct 8 with the emptying duct 2.

A spring 23 secured upon the plug 20 carries into the base of the porcelain basin 1 and also comprises a profile made up of curves 2) c d having large radii of curvature.

Upon the upper edge of this duct 2 is formed the seating 3 for the valve 4 provided with guiding wings 5.

The emptying duct 2 and the overflow duct 8 25 join each other directly without any intermediate chamber, without any projection and at an acute angle.

Further, the section of the emptying duct 2 is substantially equal to that of the overflow duct at the intersection of these two ducts, thereby again avoiding any projection at this intersection. Consequently, the streams of water follow the ducts 2 and 8 without undergoing any sudden deflection and without forming eddies and they thus reach the discharge duct 1 which is extended by the waste pipe 10.

The three ducts 2, 8 and 1 are of substantially constant section over the whole of their length.

These three ducts 2, 8 and I constitute in fact an arrangement havingrounded internal forms with no sharp angles with perfectly smooth walls having no projections, free from bafiles and with no members for controlling the valve secured upon the walls of the overflow duct or of the discharge duct.

Finally, each of the three ducts 2, 8 and I comprises at the opposite end to the junction between these ducts, an orifice 3, I0, 80 having a section substantially equal to the mean section of the said duct.

The combination of these various features possesses a great number of advantages.

In the first place the walls of these ducts 2, 8,

i comprise no points upon which the impurities suspended in the polluted water can become at- A sponge formed for example by a cloth of.

suitable size forming a headmounted on the end of a flexible rod will then be inserted in the emptying duct 2. This head will advantageously when out of use have a section equal to the largest section of the three ducts mentioned above, the dimensions of this head being capable of reduction by one-third on account of its elasticity. This sponge thus follows, without difiiculty, the three ducts having a continuous profile and which are free from projections and are made up of curves of large radii so that the sponge rubs upon all points of the walls and consequently cleans them perfectly.

The facility of removing and replacing the valve 4 and the whole of its controlling device obviously encourages the user to clean the sanitary appliance frequently and consequently keep it in the greatest state oi cleaniiness. V 7

In this appliance there is a surecooperation between the rigid controlling rod and the profile of the ducts which have large radii of curvature for cleaning and maintaining the appliance under the best conditions of hygiene.

Further, the above combination possesses the advantage of distributing thepressure uniformly and consequently of reducing wear to a minimum and distributing this wear uniformly; it removes any risk of jamming oi the parts, avoids any choking of the valve by the accumulation of heavy-materials and permitsthese heavy mateflow.

. Moreover, in the wash basin illustrated in Figurel,v the valve 4 on the emptying duct 2 is advantageously constructed in the following manner:--

The bearing surface4 of the valved upon the seat 3 does not extend to the upper edge of the cone formed by this seat 3 thereby avoiding any dam-age and scratching of the layer of enamel 95 which coversthe ceramic body of the appliance.

Further, the valve 4 is extended by a part 4 forming a cap having a diameter Dgreater than the larger diameter d of the cone forming. the seat 3, so asto cover the upperend of this cone and facilitate handling the valve 4 if the latter is replaced in position before the controlling mechanism l 5 has been mounted in place. Here again, this arrangement co-operates in facilitating dismounting and cleaning.

Finally, in the wash basin illustrated in Figure 1, a closing member such as the plate 31 is mounted upon a stemtfl itself secured upon the controlling rod l6 of the waste valve l. This plate 3| covers the flow aperture fiwhich connects the overflow duct 8 with the basin I, when currence of the noise and gurglingwhich tend to be produced when water flows out of the basin i.

In the embodiment illustrated in Figure 3, the rigid control rod 56 co cperates in guiding the waste valve 4, thereby further removing any danger of jamming. For this purpose, the control rod i6 is formed of two parts S5 I6 mounted adjustably relative to one another, for example, by means of a device comprising a screw threaded rod a nut 5! and a lock-nut 52. Further, the part 56 of the control rod I6 comprises at 54 a guide for the end 53 of the waste valve 4.

This arrangement possesses various advantages.

In the first place, on account of the fact that the valve 4 is guided at 5 5 by means of its tail 53, no guiding wings are required on this valve,

the two parts I6 I6 relative to one another,

permits the position of the guiding end 54 to be regulated so that this end is always directly below the tail 53 of the valve 4 in spite of any irregularities which may occur in the casting and manufacture of the body of the wash basin.

The wash basin illustrated in Figure 3 also comprises a seat of special construction for the waste valve. This seat is formed by a metal ring 3 connected to the body of the wash basin I by screws I 48 which screw into the seat and bear by means of their heads upon the external surface of this body I, thereby providing a secure attachment of the ring upon the body.

This metal ring presses upon a shoulder M3 in the body I of the wash basin, with the interposition of a washer M4 having a U-shaped cross section and made for example of malleable lead.

This washer is squeezedinto the interior of the emptying duct 2 and the excess metal is then removed in order to permit an emptying duct 2 to be obtained having a perfectly smooth inner surface which comprises no projections capable of retaining the impurities suspended in the polluted water.

The free space 142 formed between the ring 3 and the body I is filled with a cement.

In this way, the seat is securely mounted, a good fluid-tight joint is provided and an emptying duct having a perfectly smooth inner surface is obtained. V

In the embodiment illustrated in Figures 5 to "7, the sanitary appliance is a bath.

' The overflow duct 38 enters the body IOI of the bath laterally at l 70 through an orifice which itself forms the flow orifice. A ring 18 connected to this body IOI by sealing studs 19 comprises a neck 16.

The cap I20 forming a plug is connected in an easily removable manner, for example by a bayonet joint 86 to the attachment neck 16.

An operating lever I22 turns freely in the removable plug l20. By means of an eccentric I it controls the operating rod H6 which lifts the waste valve I64, this rod having a profile which greatly facilitates mounting it in the overflow duct I08 and also its dismounting.

The stem 8! of the operating lever I22 comprises a closure forming extension l3l which is adapted to close the flow aperture ")9, thereby avoiding the noise which usually accompanies the flow of water through to the waste pipe H0.

The bath illustrated in Figures 5 to '7 comprises a valve seat constructed in the following manner:-

A metal ring 3 is again secured to the body of the basin by screws I40 as already explained with reference to Figure 4. This metal ring presses upon a packing I45 made of malleable metal for example of lead, and this packing I45 contracts slightly under the pressure exerted by this ring.

The excess material projecting into the emptying duct is removed so as to give this duct a per- Iectly smooth surface.

The free space I42 formed between the ring 3 and the packing M5 is filled with a cement.

In this way, the technical advantages already described with reference to the example illustrated in Figures 3 and 4 are obtained.
