Description
Jan. 13, 1970 FIG] G- J. GAINEY OVERFLOW DRAIN -Fi1ed Oct. 18, 1967 United States Patent 3,489,285 OVERFLOW DRAIN George James Gainey, New York, N.Y. (Drawer M, Port Jefferson Station, N.Y. 11776) Filed Oct. 18, 1967, Ser. No. 677,003 Int. Cl. B01d 35/02 US. Cl. 210463 1 Claim ABSTRACT OF THE DISCLOSURE A sink overflow drain tube and strainer comprised of adapters for various sized drain outlets, tubes of differing heights which may be removably engaged with said adapters, and strainer structures which may be removably engaged with the upper end of said tubes.
This invention relates to an overflow drain tube adapted for usage with deep sinks such as those commonly utilized in washing glasses and dishes in restaurants, soda fountains, and other similar establishments. Adapters permit insertion of the drain tube into sink drains of various diameters and the tube may extend 4" or more, with 8" preferred, upwards from the drain surface at the sink bottom so that a corresponding water level may be main tained in the sink for washing purposes. A strainer, which may cooperate with a funnel-shaped top surrounding the strainer, is fitted to the upper end of the tube in order to prevent solid matter which may be suspended in the contained dish water from entering and clogging the sink drain proper.
Although we do not wish to be limited thereto preferred materials are Lucite for the sink tube, and Alathon for the adapters and fittings. Also, plastic materials with physical properties similar to polyethylene may be used. The parts of the described apparatus are preferably injection molded, although the sink tube proper may be extruded and then cut into desired lengths.
It is thus an object of this invention to provide means for establishing any desired water level in a deep sink. Also, it is an object to provide additional means for preventing floating solids contained in the cleaning water thus provided from clogging and stopping the coacting sink drain.
The above and other objects and advantages will become more apparent as this description proceeds and reference is had to the accompanying drawing forming a part of this specification.
FIGURE 1 is a sectional view of the drain tube apparatus with the lower drain adapter and upper strainer removably engaged therewith.
FIGURE 2 is a perspective view of the lower adapter solely.

FIGURE 3 is a plan view of the upper strainer structure.
FIGURE 4 is a sectional view of the upper strainer structure.
FIGURE 5 is a sectional view of a modified form of the lower adapter structure.
FIGURE -6 is a sectional view of another modified form of the lower adapter structure.
FIGURE 7 is a perspective view of an imperforate inverted conical member surrounding the perforated screen of FIGURES 3 and 4.
Referring to the drawing in more detail, 1 represents a tube preferably of circular shape and provided with a removable drain adapter 3 at its lower end and a removable strainer 5 at its upper end. Element 5 is perforated in any suitable manner to permit the flow of overflow wash water therethrough. Elements 7 and 9 constitute the modifications of the drain tube adapters previously referred to and permitting tube utilization in removable engagement with sink drains of diameters of various sizes. Elements 3, 7, and 9 are representative of adapters which may be interchangeable or removably engaged with each other for the forementioned purpose.
The conical member 11 may be secured to strainer 5 in the arrangement shown by heat welding, cementing, or by molding these elements integrally. Its usage is particularly desired when washing glasses as it permits emptying ice cubes therein.
I claim:
1. In combination with a sink drain outlet, a filter means comprising a tubular member with an adapter removably engaged at a first end of said tubular member, a frustoconical perforated screen means connected to said tubular member at the other end, said adapter constructed and arranged so that it positions and supports said tubular member in removable engagement with the sink drain outlet, and an imperforate inverted conical member open at the top and extending above and annularly surrounding said perforated screen.
