Application filed February 10, 1914, Serial No. 817,916. Renewed Sc pt embei 2, 1916. Serial No. 118,312.
- Connecticut, have invented certain new and useful improvements in Drains for Sinks, of which the following is a full, clear, and
exact description.
This invention relates to a drain or waste applicable to kitchen sinks, but certain'features of my improvements are not limited to this particular application.
The prin'iary object of the invention is to provide a drain fixture in which the strainer may be very readily inserted into and removed from the outlet bushing or shell in the sink bottom, and wherein an ordinary 1 stopper ot'rubber, metal, or the like, may be readily suhstiti-lled for the strainer when it is desired to- [ill the sink with water. It is also proposed to furnish a lixl-ure of the type indicated in which the strainer, or the stopper or plug may be seated in the same seat in [he bushing and firmly held therein to serve its intended purpose.
To these and other ends, the invention consists in thenovel features and combinations of parts to be and claimed.
'11] the accompanying drawing,

ing the strainer in place in the outlet shell or bushing.
Fig. 2 is :1V similar View, showing the stop- .peror plug in its seated position.
75 detached,- and Referring to the drawing, 10 is an outlet bushing or shell, adapted to be secured in thorusual manner'in an opening in the botis a bottom view of the strainer (lethe opening formed in the latter. A nut (not shown) engaging the screw threads 1:2
on the enter .or of the bushing is adapted to clamp the bushing in place, and the lower end of the tushing has secured thereto in a Suitable manner the customary waste pipe 13, as shown in Fig. 5. Atthe upper end or mouth 01 the bushing, the latter is proyided with i smooth beveled inner surface ll, the lower margin or boundary of which projects out slightly into the open interior part of the )ushing in such a manner as to present a shoulder 15. In other words, the lower edge )f the bei eled seat in the inlet mouth of the bushing is of less diameter than the imerior diameter of that portion of the bush ng wall which is immediately below the szat. This provides a locking shoulder f0] suitable securing lugs 16 of a strainer 17, adapted to be seated and held in the moat 1 of the bushing in the manner shown in Fi g. l.
The strait or 17 is preferably formed of, a perforated s ieet metal disk, and the lugs 16 are preferably formed integral with the strainer dislby bending down radial extensions project ing integrally from the strainer blank. The lugs 16 are preferably curved,
as shown, and the strainer is so fitted rela tirely to tln seat 14 of the bushing that as the strainer is forced downward into the bushing. tlu lugs 16 in sliding 'down' over the beveled :urface of the seat will be forced inward unti' their lower ends in passing below and be) end the shoulder 15 more outward as the 'esult of the spring in the metal, and thereby lock the strainer firmly in its seat. \Vher it is desired to remove the strainer, thii can be readily efi'ected by insci-ting a kn fe, or other instrument, into the space between the strainer and the seat 14,
,. so as (to pry the strainer out of the bushing.
hen the strainer has been removed an ordinary Slit pper or plug 18 having a her eled side wall may be seated in thev'beveled seat 14. in the customary manner, as shown In Figs. 2 and so that the' sink may be.
filled with water; The substitution of the strainer for the stopper and vice. versa can be efi'ected \ery quickly and easily, and the fixture is very simple,- efficient and inexpensive.
By preie'ence. the bushing 10 will be made of sheet metal so that its bull; and cost will be redu :ed as compared to a. cast metal bushing. 1:1 this case, the seat 14: will be formed by Indentation of the side wall of the tubular sheet metal blank, which may be produced, for example, by spinning a groove 19 in said Wall at the outside, which groove is so formed as to project the metal inwardly at the inner surface of the blank to form a beveled seat of proper shape. The
shoulder 15 for locking the strainer in position is, in this case, formed as a necessary incident to the creation of the beveled seat. This is a feature of some importance in producing a fixture of minimum cost.
It will be seen from the foregoing that in the preferred form of my invention which I have selected for illustration, the bushing is provided with-a substantially horizontal laterally projecting flange at the upper. end thereof, adapted to overlie the bottom wall of the sink around the opening in the latter, said bushing-being provided at the upper end or mouth thereof with a smooth, substantially upright seat .14 beveled to make water tight contact substantially throughout its area with an ordinary plug or stopper having a beveled side wall, the diameter of the bushing being enlarged immediatel below the beveled stopper seat to form a s 0111- der 15 for locking the strainer in place. It
,will be seen also that the strainer disk is of a diameter substantially equal to the-diameter of the upper portion of the stopper seat,
1 and that it is supported in said seat. substantially flush with the horizontal flange 11- by means of spring lugs depending from the periphery thereof, and adapted to engage the beveled wall of the stopper seat so as to spring said lugs inwardly as the strainer is inserted into the seat, and permit said lugs to spring outward again into locking engagement with the shoulder 15, as said lugs pass below the stopper seat. The spring lugs are of such length that when their lower ends are in locking engagement With the shoulder 15, the strainer disk to which they are attached is supported in theupper end of the stopper seat, as stated.
It will be seen that in .the embodiment shown, the flange on the upper end of the bushing is constructed and adapted to overlie the bottom wall of the sink with a wide contacting surface, so that the joint between the-bushing and'the sink, basin or tub can be readily made water-tight, and that the bushing has a wide smooth seat adapted to niake .a good water-tight contact with an ordinary plug or stop pcau are usually slightly tapered, as shown, but
7 this is not always essentiai.
