Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
130 words
In a remotely driven backscrubber device for a bath enclosure, the combination with a casing open inwardly of the enclosure, at least one cylindrical scrubber rotatably mounted in said casing and partially projecting into said enclosure, a closed compartment adjacent said casing, transmission means in said compartment, and means to drivingly connect said transmission means to said scrubber for transmitting rotation to said scrubber, of a motor case mounted remotely from said casing and said closed compartment and entirely outside of said enclosure, an electric motor drive in said case, an insulated drive line extended from said electric motor drive into said closed compartment, insulated means in said closed compartment to couple said drive line to said transmission means to transmit rotation from said remote motor drive to said scrubber
Claim 2
Dependent Claim
130 words
In a remotely driven backscrubber device for a bath enclosure, the combination with a casing open inwardly of the enclosure, at least one cylindrical scrubber rotatably mounted in said casing and partially projecting into said enclosure, a closed compartment adjacent said casing, transmission means in said compartment, and means to drivingly connect said transmission means to said scrubber for transmitting rotation to said scrubber, of a motor case mounted remotely from said casing and said closed compartment and entirely outside of said enclosure, an electric motor drive in said case, an insulated drive line extended from said electric motor drive into said closed compartment, insulated means in said closed compartment to couple said drive line to said transmission means to transmit rotation from said remote motor drive to said scrubber
Claim 3
Dependent Claim
59 words
The remotely driven back scrubber specified in claim 1, and said casing and said compartment being unitary and being adapted to be mounted on a wall of said enclosure in position for said scrubber to project beyond said wall into said enclosure in convenient position for scrubbing, a cover of said compartment having a recess forming a soap tray.
Claim 4
Dependent Claim
54 words
The remotely driven back scrubber specified in claim 1, and said cylindrical scrubber comprising, a waterproof core, a resiliently compressible tube on said core, an axle in said core a spring-wire axle frame drivingly supporting said axle in said core, and journal means on the sides of said casing for rotatably supporting said axle.
Claim 5
Dependent Claim
67 words
The remotely driven back scrubber specified in claim 3, and there being a plurality of back scrubbers in said casing, said transmission means including axle means in each cylindrical scrubber journalled in the sides of said casing, an element on one end of each axle means extending into said closed compartment, said transmission means being drivingly connected to said one ends for imparting rotation to said axles.
Claim 6
Dependent Claim
55 words
The remotely driven back scrubber specified in claim 4, and said means to couple said flexible drive line including, a coupling element in said compartment related to one of said one axle ends, and a connecting element on said drive line drivingly connected to said coupling element for rotating said transmission means and said axles.
Claim 7
Dependent Claim
61 words
The remotely driven back scrubber specified in claim 1, and there being a plurality of cylindrical scrubbers in said casing, each scrubber including a waterproof core, a scrubber tube on the core, an axle frame in each core drivingly engaging said core, an axle supported on each axle frame, journal means on the sides of said casing for journalling said axle.
Claim 8
Dependent Claim
38 words
The remotely driven back scrubber specified in claim 6, and a drive element extending from each axle into said compartment, said transmission means engaging said drive elements for imparting rotation to said axles and to said scrubber tubes.
Claim 9
Dependent Claim
36 words
The remotely driven back scrubber specified in claim 7, and said transmission means including driving means connected to said axles, and said means to couple said drive line to said transmission means including detachable connecting elements.
