7 Claims.
The invention relates to a combination drain and strainer of the type commonly employed for sinks, basins and other types of containers and plumbing fixtures.
An object of the invention is to provide a drain and strainer of the character described which may be quickly and readily installed without necessarily requiring expensive and specialized labor With simple and ordinary tools, and at the same time provide a fitting of the character described which will be absolutely sealed against leakage and one that will last substantially indefinitely.
Another object of the invention is to provide a drain of the character above which may be readily removed and replaced without the use of putty or paint or other sealing compounds.
A further object of the invention is to provide a drain fitting of the character described in which all torsional strain is eliminated in sealing the fitting in a sink or the like, thereby enabling the use of substantially lighter Weight material which may be fashioned by stamping, spinning or drawing, and hence providing a fitting whichis easier and cheaper to manufacture than similar types fittings heretofore available.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawings and description may be adopted within the scope of the invention as set forth in'the claims.
Referring to said drawings:

members used in the modified form of construction.
Figure 9 is a partial vertical sectional view of a further modified form of support for the drain.
Figure 10 is a plan view of one of the parts used in the form of construction illustrated in Figure 9.
The combination drain and strainer of the present invention and as illustrated in the accompanying drawings, comprises a tubular member II which is adapted for mounting through an opening I2 in a wall I3 of a container or the like, the wall I3 being here arranged as in typical sink construction with an enlarged annular embossment I4 surrounding the opening I2 and a beveled surface I6 on the inner side ll of the Wall providing a shallow socket surrounding the opening. The upper end of the tubular member is provided with a transversely extending flange I8 which is adapted to seat against the beveled surface I6 of the wall in said socket so as to dispose the outer peripheral edge I9 of the flange substantially flush with the inner side ll of the wall.
In accordance with the present invention, means is provided for sealing the tubular member in the opening 8 without the use of putty or paint or other sealing materials and to seal the member in the opening in such a manner that the member may be readily removed and replaced if desired. This means consists briefly in the use of a non-torsional, longitudinally expandible device mounted on the member below the wall I2 which functions together with an appropriate gasket for clamping the wall between the flange I8 and the gasket compressed at the under side of the wall. In the present construction, a gasket 22 of annular form and compressible material, such as rubber or the like, is mounted around the member II at the under side of the embossment I4 and is provided with a tapered top portion 23 adapted to enter the opening I2 between the member I I and the embossment to seal the tubular member in the opening. The longitudinal expansible means mounted on the member for compressing the gasket in the opening I2 and against the under side of the embossment as aforementioned, consists of a backing ring 24 surrounding the member II and movable longitudinally thereon against the under side of the gasket and which is pressed upwardly against the gasket in the present form of the invention, by means of a plurality of screws 26 carried by a fixed annular ring member 21 mounted on the tubular member in longitudinally spaced relation to the backing ring 24. The ring 21 may be fixed on the tubular member in any suitable manner as by sweating or clamping the ring in place or by use of offsets or abutments on the member. Preferably the side wall of the tubular member is itself provided with a transverse offset in one form or another for supporting the ring, such as here shown by the provision of an annular recess 28 in the side wall of the member in which the ring is mounted. To secure the ring in such recess, the ring is preferably formed of a plurality of sections 29 and 3| so that the same may be assembled around and clamped in the recess 28. Preferably, the opposite ends 32 and 33, and 34 and 36 of the sections are provided with longitudinal shoulders which may be clamped togetherthe recess and the latter extending around the base of the gasket 22 to hold the same in place. The screws 26 may be thread-ed through the body ofv the ring 2'! or if desired in view of the relative thinness of the ring, the screws may be carried in threaded inserts in the body of the ring or threaded through nuts supported by the ring. It will now be clear that the installation of the fitting is extremely simple and requires merely the placing of the member H through the opening l2 to seat the flange I8 on the beveled surface lfi of the container wall, fastening the sectional ring 2'! in place in the recess 23 of the .member and then extending the screws 26 against the under side of the backing ring 24 so as to compress the gasket 22 into the opening and clamp the container wall between the flange l8 and the gasket. Removal of the fixture from the container Wall is readily effected by a reversal of the aforesaid operations, including a release of the screws 26 and a removal of the clamping ring 2'! to enable withdrawal of the member II from the opening. The ease and facility of installing and removing the fitting is of substantial importance, due to the fact that such fittings are frequently damaged. either at the time of, installation or subsequently, and with the present construction the fitting may be removed and replaced by one not having special knowledge and experience in plumbing devices and accomplished by the use of simple and ordinary tools Without putty or paint or other sealing compounds.
The member I in. addition to providing a drain for a container with which it is attached, is preferably formed with a' top refuse receptacle for receipt of a combination. refuse basket and plug. As here shown the. member is provided with an enlarged upper portion 43, substantially of the size of the opening l2, and providing such a refuse receptacle. in the drainv and which connects with a. reduced cylindrical portion 44 normally designated the tail piece of a drain fitting. Between the portions 43 and 44 the member II is formed with a longitudinally inclined or tapered wall portion 46 which is adapted to support'a refuse basket 41 mounted in the enlarged portion 43'. The basket 41 is provided with a bottom wall 48 and a perforate annular side wall it and is preferably slightly smaller in diameter than the enlarged portion 53 of the member, so as to seat the lower bottom edge of the basket medially on. the inclined wall 46. The upper end 52 of the side wall 49 of the basket is preferably flared outwardly to snugly engage the inner side wall of the enlarged portion 43.
Means is preferably provided for opening and closing the drain by either raising the basket from wall portion it or drawing the same thereto. As here shown, there is mounted across the tubular member in the refuse portion 64 thereof adjacent the base of the inclined wall 46, a bar strainer 53 which is preferably fixedly secured in the tubular member, such as here shown by rolling an inwardly extending bead 53 in the wall portion of the tubular member into an annular recess 56 provided around the periphery of the bar strainer 53. In the present construction the means for raising and lowering the basket consists of a stem 51 which is secured to the bottom wall 48 of the basket and which extends longitudinally through a central opening 58 in the bar strainer, the upper end of the stem being extended through an opening 59 in the bottom wall 48 of the basket and threaded into the base of a knob 6| in the basket so as to clamp the bottom wall 4'! therebetween. Secured to the stem adjacent the strainer 53 are a plurality of winglike projections or lugs 62 which may be passed through enlarged side portions 63 of the opening 58 when the basket is in seated position, and which are adapted to engage with thread portions 64 in the opening upon rotation of the stem, so as to draw the basket down tightly against the inclined Wall portion 65. In elevating the basket the same is rotated and lifted by means of the knob 6| to position the lugs 62 on the top surface of the strainer where the same may be supported intermediate the side opening 63 to support the basket in elevated position over the inclined wall portion 46.
A modified form of longitudinal expansible joint is illustrated in Figures 6 to 8 of the drawings, wherein the tubular drain member I is drawn tightly against the upper surface of a container wall [3' about a drain opening by means secured against longitudinal displacement on the member at the under side of the Wall and operating to wedge a gasket 23 longitudinally against the under side of the wall l3 and into the drain opening of the wall, so as to seal the fitting in the container wall opening. A form of securing means here illustrated provides a straight longitudinal force against the backing ring 24', as in the first embodiment, so that the tubular member is not subjected to any torsional stress and may, therefore, be constructed of light weight material. The means for forcing the backing ring 24 longitudinally towards the under side of the container wall here consists of a plurality of cylindrical sections 66 which are adapted to fit around the tubular member I I and are provided with an outwardly and upwardly sloping top flange 61 which is adapted to engage a complementary sloped under side 68 on the backing member 24'. The sections 96 are held against longitudinal displacement by means of a lug 69 carried by each of the sections and engageable in the circumferential recess 28 provided in the front member. Surrounding the sections 66 is a sleeve H which is driven longitudinally over the sections so as to cause them to snug-1y embrace the drain member I and press upwardly against the backing ring 2'3. The assembling of the sev eral parts is illustrated in Figure 7. The gasket and backing ring are first positioned on the tubulardrain member adjacent the under side of the wall l3 and the sections 65 are next assembled with the lugs 69 seated in the recess 28 and the inner lower'edge of the flange 6'! engaged with the under side of the backing ring. In this initial position the sections 66 incline outwardly from the side of the drain member, as shown in Figure 7. The sleeve H is then slid longitudinally over the drain member so as to engage the upper end 12 of the sleeve around the base of the sections 66. The sleeve is then driven longitudinally so as to cause the sections 65 to fulcrum inwardly about the lugs 69 and to thereby wedge the backing ring 24 and the gasket longitudinally against the under side of the container wall.
A further modified form of the support for the drain member I I" is illustrated in Figure 9, wherein the relatively fixed supporting ring 21 is held against longitudinal movement on the member by means of a split ring 16 carried in the annular recess 28". The split ring 16 is preferably of circular cross section and the ring 21" is preferably provided with a collar portion .11 which jointly engages the side of the member II" and the outer side of the ring 16, so as to confine the ring in the recess and to hold the member 21" against longitudinal displacement. The ring as illustrated in Figure 9 is preferably of a size causing the ring to protrude laterally from the recess and from the side wall of the member H". A plurality of screws 26'' are carried by the ring member 21" as in the first embodiment, and as here shown the screws are threaded through nuts 18 which are supported on the upper surface of the ring member. As a further feature of distinction over the first embodiment, the upper ends 19 of the screws are mounted in an annular recess 8| in the backing ring 24" so as to hold the screws against radial displacement on the backing ring. The recess 8| is preferably formed in the backing ring so as to provide a protuberance on the top surface s of the backing ring which tends to crowd the gasket 23" towards the wall of the member II" and towards the container wall l3. Also, the gasket 23 is preferably widened at the inner edge thereof surrounding the member II" and is arranged with both of its top and bottom surfaces 82 flared or inclined divergently towards the inner edge of the gasket. The upper surface of the backing ring 24" is preferably beveled to conform to the flared or inclined abutting surface of the gasket. Preferably, the gasket and rings and screws, etc., are completely enclosed within a casing 83 which is provided in the present embodiment with a cylindrical side wall 84 which is adapted to slide over the rings 24" and 21" and to extend from the under side of the wall I 3" to below the heads of the screws 26". The lower end wall 86 is provided with a central opening for engaging over the member II". By the use of the member 83 the several parts of the fitting are shielded from view and may be left in unfinished metal without detracting from the appearance of the fitting.
