ATTORNEYS 3,066,802 Patented Dec. 4, 1962 tire 3,666,862 FLOR DRAEN Walther Ltler, Friedrich-Ebert-Strasse 43, Markldeeberg-mitte, Germany Filed Jan. 5, 1960, Ser. No. 532 19 Claims. (Cl. 210-163) This invention relates in general to iioor drains and 1n particular to a new and useful oor drain including means for sealing the skirt portion thereof with the surrounding floor installation and including a flushing opening at the top of a grate assembly for access to a waste trap portion. The grate assembly includes one or more rings for elevating the access top grating, one of the rings including a flushing ring for directing fresh cleaning water into the drain and further including rings for adjusting the height -of the various sub assemblies for adapting the grate/construction to the thickness of ooring and the elevation of connecting drains at the locations in which the drain is to be installed.
The present invention is an improvement in drain constructions generally and in a preferred embodiment includes a bowl `shaped member which connects to a downwardly inclined drainage pipe and is separated therefrom by means of a partition wall to effect a U-shaped drain trap. A feature of the present construction is that the grate which is arranged over the bowl drain includes an access cleaning pipe portion which is arranged directly over the waste trap portion defined by one wall of the bowl member and by the partition wall. The locatio-n is such to permit access to the complete waste trap portion and to portions of the drainage pipe leading away from the bowl.
A feature of the invention is the provision of a novel skirt construction which permits the running of a waterproof tar paper or similar material into a groove surrounding the skirt and further including means for anchoring and sealing this material at this location.
To accommodate for various thicknesses of floor construction, there is provided a grate assembly including ring members which are fitted into a supporting lip construction on the skirt portion of the bowl member to provide an elevation for an access drain which is to be located on the top of the finished iioor. One or more of the rings is advantageously made either with a series of projections 4and recesses which can be aligned and interlocked to establish one elevation of the top grating member, or, the ring projections `are offset from the recesses so that projecting portions rest on projecting portions to provide a higher elevation for the finished top grating.
In one embodiment there are provided spacer rings having inclined teeth to permit gradual shifting of one tooth in respect to the other to change the elevation of the top portion of a pair of such rings. The drain construction permits the insertion of a flushing ring either directly on the skirt portion -of the bowl or over one or more of the spacing collars to achieve the elevation desired.
Accordingly, it is an object of this invention to pro vide an improved floor `drain construction.
A further object of this invention is to provide a floor drain construction including a skirt portion having improved means for clamping and sealing a waterproof material thereto.
A further object of the invention is to provide a floor drain construction including a bowl member arranged to drain through a conduit extending downwardly at an angle from one side thereof Iand including a partition extending downwardly into the bowl member adjacent the conduit to define a waste trapping portion. Which is accessible through an improved grate access opening construction directly thereabove to afford access for cleaning and removal of waste from this portion of the bowl and conduit.
A further object of the invention is to provide a floor drain including a skirt portion adapted to support one or more rings at least one of which is adjustable to effect a change in height of the top of the grating.
A further object of the invention is to provide a floor drain including a skirt portion adapted to support a flushing ring thereabove.
A further object of the invention is to provide a floor drain which is simple in design, rugged in construction and economical to manufacture.
The various features of novelty which characterize the invention are pointed out with particula-rity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and specific objects obtained by its use, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
In the drawings:
FIG. l is a vertical transverse section through the floor drainage body construction in `accordance with the invention;
FIG. 2 is `a fragmentary top plan view partly broken away of the drainage body illustrated in FIG. l;
FIG. 3 is a fragmentary perspective view of an intermediate ring construction for use with the drainage body;
FIG. 4 is a fragmentary vertical section on an enlarged scale of the skirt portion of the drainage body;
FIG. 5 is a view similar to FIG. 4 but illustrating another embodiment of skirt construction;
FIG. 6 is a transverse vertical section similar to FIG. 1 of another embodiment of drainage body;
FIG. 7 is a fragmentary top plan View of the drainage body illustrated in FIG. 6;
FIG. 8 is a partly sectional bottom plan view of a frame member for receiving a iiushing cover, taken `along line 8-8 in the embodiment illustrated in FIG. 6; and
FIG. 9 is a fragmentary bottom plan View of the grate of the embodiment illustrated in FIG. 6.
Referring to the drawings in particular, the invention embodied therein includes a drainage body generally designated 1 which comprises a bowl portion S0` which connects at the upper portion of one end of a discharge pipe portion 2. The bowl portion 50 and a portion of the discharge pipe 2 `are surrounded by a skirt portion '52 which connects at one side to the discharge pipe 2 and is provided with an outstanding flange 18 at other locations. The skirt portion 52 is substantially flat and includes a downwardly extending partition wall portion 3 which is spaced from the wall of the bowl portion 50 adjacent the pipe 2 and defines therewith a waste collecting chamber or space 41.
In accordance with the invention the skirt portion 52 includes an upstanding annular liange or lip 54 adapted to receive an intermediate annular member 4 which is provided for adjustment of the height of the top covering of the drain and as a support for a collar member 5.
The collar member 5 includes an upstanding or raised outer rim and an inner ledge for supporting a flushing ring 6. The flushing ring 6 is provided with an annular lcondu-it 7 and downwardly inclined bores 8 which are directed radially with respect to the `access of the ring 5 r for directing flushing water tangentially into the drainage body 1 from a fresh water conduit supply 9.
in the embodiment indicated in FIGS. 1 to 4 the iiushing ring 6 is provided with a raised outer rim and an inner ledge for supporting a frame il()` in which a circular grate 11 is rotatably supported.
The collar 5 is provided with a threaded opening 12 for connecting an admission pipe (not shown) for liquid to be drained into the drainage body 1. The opening 12 is embedded within the floor and liquid which is directed therethrough strikes a baffle plate member 56 having a series of spaced openings 58 therein. Some of the liquid enters the openings 58 and the rest is directed downwardly into the bowl 50 for discharge to the pipe or conduit 2.
In accordance with the invention means `are provided to shift Vthe elevation of the collar in accordance with the location of the pipe which is to be connected to the opening 12. These means include the annular member 4 having tooth-like projections and recesses 36 which may be 'aligned with similar recesses and projections 13 defined on the annular lip 54 of the skirt portion 52. With such a construction it is possible to change the elevation of the ring 5 by double the height of the teeth 36 of the ring 4 when the teeth and recesses are aligned with the projections 13 of the lip 54 rather than with the recesses between the projections.
Another embodiment of intermediate ring 37 is indicated in FIG. 3. The ring 37 is provided with projec- .tions 14 extending upwardly and projections 15 extending downwardly. When using .such a ring it is possible to use it inbetween the ring 4 and the lip S4 either in a manner in which the projections 14 and 15 t into corresponding recesses between teeth 36 and 13, respectively, or they are placed in vertical alignment with the projections 36 and 13 to achieve a height change of four times the depth of the projections.
Instead of using any tooth like projections, plane spacer rings similar to the collar 5 may be used. Gradual changes of elevation may be achieved by a construction which includes inclined flanks 38 such as indicated in adjustment rings 16 and 17 in FIG. 6, Relative rotation of these rings would then be effective gradually to change the elevation of the top `of the uppermost ring.
In accordance with another feature of the invention, the sealing ange 18 extends outwardly from the skirt portion 52 and surrounds the body 1. A circular depression 19 is defined at the location Where flange 18 joins the bowl portion 50. As indicated in FIG. 4 a tar paper 24 is stretched across the flooring in which the drainage body 1 is installed, and its end is tucked into the depression 19. A sealing material or putty 20 is then applied over the tar paper. Grooves 21 and 22 which are cut into the drainage body 1 within the depression 19t serve to afford better anchorage for the sealing material after the sealing material has become hardened. The flange or lip portion 54 may have a peripheral portion 23 protruding slightly above the depression 19 for better anchorage of the sealing substance 20.
In the embodiment indicated in FIG. 5, a plastic sheet 2'5 is directed into a similar depression 19 and wedged therein by split ring portions 26 and wedges 27 as shown in FIG. 2.
In the embodiment shown in FIGS. 6 to 9 the drainage body 1 is substantially similar to the drainage body 1 of FIGS. l to 4, however a partition wall 3" is provided which is curved at its upper end and includes a lower inclined wall portion 3 which is spaced from a bowl portion 50. A discharge pipe 2' is provided which is similar to pipe 2 of the rst embodiment.
While in the embodiment shown in FIG. 1 there is provided an annular threaded opening 411 in which is provided a cleaning shaft 28 capped by a cover 64, in the embodiment illustrated in FIG. 6 a cleaning shaft 28' is defined centrally of the bowl 50 directly above the curved portion 3' of the partition wall. The shaft 28 is formed by an elongated pipe 29 which is threaded onto an externally threaded annular portion 60 of the wall 3', which extends above the bowl portion 50". A pipe 31 has an annular ledge which contacts an annular portion 62 of the pipe 29. The pipe 31 has an upper square frame adapted to receive a square cover 32. It will be understood that the bafiie member 56 of FIG. l may be removed from the inwardly ledge of ring 16 if the cleaning shaft 28 is to be used in a particular floor drain installation.
In addition to the adjustment ring 17 there is provided in this embodiment a grate supporting member 34 which receives a substantially rectangular grate 33 having several drain openings therein and a central opening to accommodate the cover 32 and the upstanding frame portion of the pipe 31. The member 34 rests with an annular ledge 35 (FIG. 9) on an appropriate upper proled portion of the ring 17.
In the embodiment illustrated in FIG. l, the highest point at the inside of the bowl portion 50 is located at 39 at the juncture with the pipe 2i. This point is located directly below the cleaning shaft 28- and thus access may be had to either the waste chamber portion 41 or the pipe 2 for cleaning purposes. Similarly, in the embodiment illustrated in FIG. 6, the central shaft 28l may be reached by removing the cover portion 32 which attords access to the curved portion 3" of the partition wall as Well as to a portion of the pipe 2".
While specific embodiments of the invention have been shown and described in detail to illustrate the applic-ation of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
