Abstract
Abstract A bathtub or sink scrubber is provided with an electric motor for rotating a brush or other polishing member. The motor is contained within a first dome-like housing and supported by a rigid support member. A second dome-like housing is provided in movable relation to the first dome-like housing and the second housing has a handle member extending therefrom which is adjustable about an axis within the second housing permitting the bathtub scrubber to be universally positioned in relation to the handle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
A mechanized scrubber adapted to clean and polish sinks and bathtubs, and scrubber comprising: first housing means having drive motor means mounted therein, said drive motor means including a drive shaft; said drive shaft projecting from said first housing means and being adapted for mounting a brush member for polishing and cleaning said sinks and bathtubs which said brush member is rotated by said drive shaft; second housing means adjustably connected with said first housing means to enable the position of said second housing means to be selectively positioned relative to said first housing means; a handle for said scrubber; and handle support means disposed within said second housing means; said handle adjustably connected to said handle support means to enable the position of said handle to be selectively adjusted; said second housing means having a slot formed in the top thereof through which the lower end of said handle can project into said second housing means; said handle support means including a member to which said handle lower end is pivotally connected, said member having an arcuate groove formed therein to limit the motion of said handle, and further including a digitally operable screw to position said handle at a selected position by tightening of said screw.
Claim 2
Dependent Claim
208 words
A mechanized scrubber adapted to clean and polish sinks and bathtubs, and scrubber comprising: first housing means having drive motor means mounted therein, said drive motor means including a drive shaft; said drive shaft projecting from said first housing means and being adapted for mounting a brush member for polishing and cleaning said sinks and bathtubs which said brush member is rotated by said drive shaft; second housing means adjustably connected with said first housing means to enable the position of said second housing means to be selectively positioned relative to said first housing means; a handle for said scrubber; and handle support means disposed within said second housing means; said handle adjustably connected to said handle support means to enable the position of said handle to be selectively adjusted; said second housing means having a slot formed in the top thereof through which the lower end of said handle can project into said second housing means; said handle support means including a member to which said handle lower end is pivotally connected, said member having an arcuate groove formed therein to limit the motion of said handle, and further including a digitally operable screw to position said handle at a selected position by tightening of said screw.
