Abstract
Abstract The float is employed for controlling the valve of a water tank of a toilet for regulating the water level. The float has a solid core with wall structure extending therefrom forming a sealed chamber located on one side of the core. An aperture extends through the core. The volume of the chamber is greater than the volume of the core and the chamber and most of the volume of the float is located on one side of the aperture. The aperture will receive the free end of a rod which is connected to the valve. The float may be rotated around the rod and secured thereto at different angular positions to select the desired water level at which the valve is closed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
170 words
An apparatus for controlling a float operated valve means of a water tank of a toilet for regulating the water level in the tank, comprising: a float member capable of floating in water, said float member having a central axis along a given dimension, said float member having an aperture for receiving one end of a rod means with the other end of the rod means being connectable to the valve means in the water tank, said aperture being offset from said central axis whereby the length of the rod means when located in said aperture is offset from said central axis, when said rod means is located in said aperture, said float member and hence the portion of said float member between said aperture and said central axis are rotatable about said rod means whereby said float member can be secured to said rod means to locate said portion of said float member between said aperture and said central axis at different angular positions relative to said rod means.
Claim 2
Independent Claim
170 words
An apparatus for controlling a float operated valve means of a water tank of a toilet for regulating the water level in the tank, comprising: a float member capable of floating in water, said float member having a central axis along a given dimension, said float member having an aperture for receiving one end of a rod means with the other end of the rod means being connectable to the valve means in the water tank, said aperture being offset from said central axis whereby the length of the rod means when located in said aperture is offset from said central axis, when said rod means is located in said aperture, said float member and hence the portion of said float member between said aperture and said central axis are rotatable about said rod means whereby said float member can be secured to said rod means to locate said portion of said float member between said aperture and said central axis at different angular positions relative to said rod means.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1, wherein: said float member comprises a sealed hollow chamber located to one side of said aperture with no entrance thereto from the exterior.
Claim 4
Independent Claim
189 words
