Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
An enamelled bowl shaped basin having a drain at the bottom connected to a drain line and a continuous external supply of water comprising a first passageway integrally enclosed within the rim portion of the basin connected to the external water supply, a first row of holes spaced around the inside of said basin near the rim communicating with said first passageway, a second passageway integrally enclosed within the rim portion of the basin connected to the drain line, a second row of holes spaced around the inside of said basin above said first row of holes and communicating with said second passageway, at least one water supply line connected to said first passageway, valve means in said water supply line for controlling the flow of water therein, and push button means connected to said valve means for selectively positioning the valve means.
Claim 2
Dependent Claim
143 words
An enamelled bowl shaped basin having a drain at the bottom connected to a drain line and a continuous external supply of water comprising a first passageway integrally enclosed within the rim portion of the basin connected to the external water supply, a first row of holes spaced around the inside of said basin near the rim communicating with said first passageway, a second passageway integrally enclosed within the rim portion of the basin connected to the drain line, a second row of holes spaced around the inside of said basin above said first row of holes and communicating with said second passageway, at least one water supply line connected to said first passageway, valve means in said water supply line for controlling the flow of water therein, and push button means connected to said valve means for selectively positioning the valve means.
Claim 3
Dependent Claim
42 words
The basin structure as claimed in claim 1 and further comprising a second valve means in the drain line leading from the bottom drain, a second push button means connected to the second valve means for selectively positioning the second valve means.
Claim 4
Dependent Claim
146 words
The basin structure as claimed in either claims 1 or 2 wherein the first and second valve and push button means are the same structure, the valve means comprising a hollow valve body, a partition in said valve body, a valve opening in said partition, a valve member for opening and closing said opening having a valve stem on said valve extending through said valve body, said push button control means comprising a hollow cover member adapted to be mounted in fixed position, an aperture in said cover member through which said valve stem extends, a first push button on the end of said valve stem, a spring between the cover and first push button for resiliently urging said push button and valve stem in a direction to close the valve, and means for releasably retaining said first push button and valve selectively in various positions.
Claim 5
Dependent Claim
89 words
The basin structure as claimed in claim 3 wherein the releasable retaining means comprises, a plurality of notches linearly spaced on the valve stem within said cover, a plate member slidingly mounted on guide grooves within the cover member having its inner edge shaped to engage one of said notches, a spring means urging said plate member into engagement with said notches to lock the valve in position, and release means to withdraw the plate member against the force of said spring from said notch to release the valve.
Claim 6
Dependent Claim
127 words
The basin structure as claimed in claim 4 wherein the release means comprises a second push button adjacent said first push button and having a rod-like extension extending from its lower surface through an aperture in said cover member, a spring between said cover and second push button to urge said second push button away from said cover, a flange on said extension within said cover member to retain said second push button, a cam surface on the other end of said extension within said cover member, a cam follower integral with the slide plate and engaging said cam surface so that depressing the second push botton will cause the cam surface to slide the plate member out of engagement with said notch to release the valve.
Claim 7
Dependent Claim
49 words
The basin structure as claimed in claim 5 and further comprising hot and cold water lines in the water supply, said valve member being provided in each line and a push button control means for each valve mounted adjacent to each other at the upper rim of the basin.
