Abstract
Abstract An apparatus adapted for scrubbing and massaging the human body and arranged for installation in a bath-room in operative association with shower and bathtub water fixtures, which are either built in therewith or connected thereto. A scrubbing apparatus including a scrubbing head which moves up and down and rotates on itself and the movements of which are caused by a hydraulic cylinder actuated by the water pressure of the usual water supply system in a bath-room.

Claim 6
Dependent Claim
59 words
An apparatus as defined in claim 4, wherein a return pipe is secured at one end to said valve casing in communication therewith and extends away therefrom lengthwise of said hydraulic cylinder, said parallel elongated members are secured to said hydraulic cylinder and to said return pipe and the latter communicates with the remote end of said hydraulic cylinder.
Claim 7
Dependent Claim
147 words
A scrubbing and massaging apparatus for the human body comprising a vertically arranged guiding device and a scrubbing head assembly including a scrubbing head and a carriage means displaceably associated to said guiding device for movement of said scrubbing head assembly along said guiding device, said scrubbing head being mounted onto said carriage means and arranged for displacement therewith relative to said guiding device, a motor arranged to be connected to said scrubbing head assembly to displace the same along said guiding device, reversing control means for said motor operated by said scrubbing head assembly at limit positions thereof to reverse the action of said motor and wherein said scrubbing head is rotatably mounted onto said assembly and a transmission drive connects said scrubbing head to a stationary point of the apparatus to convert vertical displacement of said scrubbing head assembly into rotation of said scrubbing head.
Claim 8
Dependent Claim
147 words
A scrubbing and massaging apparatus for the human body comprising a vertically arranged guiding device and a scrubbing head assembly including a scrubbing head and a carriage means displaceably associated to said guiding device for movement of said scrubbing head assembly along said guiding device, said scrubbing head being mounted onto said carriage means and arranged for displacement therewith relative to said guiding device, a motor arranged to be connected to said scrubbing head assembly to displace the same along said guiding device, reversing control means for said motor operated by said scrubbing head assembly at limit positions thereof to reverse the action of said motor and wherein said scrubbing head is rotatably mounted onto said assembly and a transmission drive connects said scrubbing head to a stationary point of the apparatus to convert vertical displacement of said scrubbing head assembly into rotation of said scrubbing head.
