Cats eye restricted actuator with a bihemispherical seal actuating a plunger guided by a removable threaded basket guide.
A remotely actuated drain is provided by a bihemispherically sealed rod actuator restricted by a cat's eye restrictor to move in a vertical direction. This rod in turn actuates a plunger to move vertically to open the drain, the vertical motion of the plunger ensured by a central tubular guide up which the plunger stalk rod travels. The central guide is supported in the center of the drain by a threaded basket threaded into an internal thread provided in the top portion of the drain body to provide a removable anchor for the central guide. This cat's eye restricted actuator with a bihemispherical seal actuating a plunger guided by a removable threaded basket guide can be sized and fitted to a variety of vessels, including lavatory sinks, baths, and utility sinks.
1 . A drain fitting comprising:
an actuator rod transfixing an actuator sphere sandwiched by two annular bushings
a horizontal actuator mount accommodating said rod, sphere and bushings and tightened by a basket nut.
an actuator mount adapter to which the actuator mount is horizontally attached.
a drain body comprising a flanged pipe with seals and nuts to affix it to a vessel body, and to the bottom of said body is attached the actuator mount adapter.
a tailpiece attachment fitted to the bottom of the actuator mount adapter for attachment to more drainage piping.
2 . The drain fitting as claimed in claim 1 wherein a vertical slot perforation is provided in the interior of the roughly cylindrical wall of the actuator mount adapter, said slot having its center collinear with the horizontal axis of a tubular actuator mount affixed to the side of the actuator mount adapter, said slot having vertical sides spaced to allow actuator rod movement, and said slot having upper and lower boundaries that are coradial to the inner circumference of the tubular actuator mount.
3 . A threaded basket is threaded into the upper interior of the drain body to anchor a central tubular guide concentrically to the vertical axis of the drain, said guide acting to restrict a plunger rod to move only vertically.
