First Claim
1. A plumbing fixture adapted to be installed from the top side of a sink deck through a sink deck opening, said fixture including a housing having a body portion which is adapted to extend through the sink deck opening and extend below the sink deck when mounted, and a shoulder portion on said housing which is adapted to seat on the sink deck when mounted, a collar slidably movable on said body portion and of a size to pass through the sink deck opening, a threaded bore in said collar, an unthreaded bore in said housing shoulder portion, a threaded member extending through said unthreaded and threaded bores, with rotation of said threaded member from above the sink deck moving said collar axially along said housing body portion,outwardly-biased yielding means slidably movable on said body portion and being positioned within said collar and extending outwardly therefrom, such that when so extended the collar will not pass through the sink deck opening, said housing body portion having a recessed area thereon to accommodate inward movement of said outwardly-biased yielding means, whereby the plumbing fixture is adapted to be mounted to the sink deck by first compressing the yielding means into the recessed area of the housing body portion to pass the body portion and collar through the sink deck opening from above the sink deck until the shoulder portion is seated on the sink deck and the yielding means has extended after passing through the sink deck opening, the threaded member is then rotated until the collar has moved axially along the body portion and is in contact with an underside of the sink deck.

Abstract
A plumbing fixture adapted to be installed from the top side of a sink deck through a sink deck opening includes a housing having a body portion which is adapted to extend through the sink deck opening and below the sink deck when mounted. The housing has a shoulder which is adapted to seat on the sink deck when mounted. There is a collar slidably movable on the body portion and of a size to pass through the sink deck opening. A threaded bore is in the collar and an unthreaded bore is in the housing shoulder, and a threaded member extends through these bores, with rotation of the threaded member from above the sink deck moving the collar axially along the housing body portion. The housing body portion has a recessed area thereon to accommodate inward movement of a pair of outwardly-biased yielding members, such as button-shaped projections, which are associated with the collar and extend outwardly therefrom such that when so extended the collar will not pass through the sink deck opening. The fixture is mounted to the sink deck by first compressing the outwardly-extending button-shaped projections to pass the body portion and collar through the sink deck opening from above the sink deck until the shoulder portion is seated on the sink deck and the button-shaped projections have extended after passing through the sink deck opening. The threaded member is then rotated until the collar has moved axially along the body portion and is in contact with the underside of the sink deck.
