Abstract
Abstract A rotary stripper comprising a pair of spaced plates driven around a shaft and studs extending between the plates and radially spaced from the shaft; stripper members, each comprising generally hairpin shaped members, with the bend mounted around a stud and the legs extending past the shaft and beyond the periphery of the plates; the legs of each stripper member are respectively supported against excessive deflection by the drive shaft and on the other studs; retainer studs are provided radially outside the mounting studs to block separation of the stripper members from their respective mounting studs; the stripper members are laid down on annularly successive studs until the required height of the stripper is reached, whereby the stripper members are interleaved.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
166 words
A rotary stripper comprising: a plate having a periphery, a plate driving element secured to and extending normally of said plate; a plurality of studs radially spaced from said plate driving element and upstanding from said plate; at least one stripper member supported by and retained on each said stud; each said stripper member comprising wire means shaped to have two legs and said legs being connected at one end thereof in a sharp bend; each said stripper member being placed such that said bend thereof passes around and engages a respective said stud on the side of that said stud away from said plate driving element; said legs of said stripper member extending from said bend past said plate driving element, with said plate driving element extending between said legs, and said legs extending beyond said periphery of said plate at the side of said plate away from the respective said stud, whereby each said stripper member defines two said stripper legs for stripping purposes.
Claim 2
Dependent Claim
166 words
A rotary stripper comprising: a plate having a periphery, a plate driving element secured to and extending normally of said plate; a plurality of studs radially spaced from said plate driving element and upstanding from said plate; at least one stripper member supported by and retained on each said stud; each said stripper member comprising wire means shaped to have two legs and said legs being connected at one end thereof in a sharp bend; each said stripper member being placed such that said bend thereof passes around and engages a respective said stud on the side of that said stud away from said plate driving element; said legs of said stripper member extending from said bend past said plate driving element, with said plate driving element extending between said legs, and said legs extending beyond said periphery of said plate at the side of said plate away from the respective said stud, whereby each said stripper member defines two said stripper legs for stripping purposes.
Claim 3
Dependent Claim
94 words
The rotary stripper of claim 1, wherein said bend is so shaped and said legs are so placed and shaped that each said legs passes by said plate driving element and then normally passes in engagement with a different respective other one of said studs than the respective one engaged by the said bend of that said stripper member; the said other two studs engaged by the two said legs of said stripper member having respective surfaces that are generally opposed to one another and said legs engage the respective said opposed stud surfaces.
Claim 4
Dependent Claim
56 words
The rotary stripper of either of claims 1 or 2, wherein for each said stud there is a respective retainer stud upstanding from said plate and spaced closer to said periphery of said plate than said stud; said bend of each said stripper member being positioned between a respective said stud and its said retainer stud.
Claim 5
Dependent Claim
29 words
The rotary stripper of claim 1, wherein said studs are uniformly spaced annularly around said plate driving element and are at equal radial distances from said plate driving element.
Claim 6
Dependent Claim
68 words
The rotary stripper of any of claims 1, 2 or 4, wherein said stripper members are interleaved with each other such that each successive said stripper member is laid atop the next preceding said stripper member in a stack thereof and successive said stripper members in said stack being mounted on annularly successive said studs, whereby said stripper members are uniformly arrayed annularly around said plate driving element.
Claim 7
Dependent Claim
60 words
A rotary stripper of claim 5, wherein there is a plurality of said stripper members on each said stud and each said stripper member on any one said stud is spaced from the adjacent said stripper member on that said stud by a distance equal to the thickness of the said stripper member multiplied by the number of said studs.
Claim 8
Dependent Claim
52 words
The rotary stripper of claim 5, wherein for each said stud there is a respective retainer stud upstanding from said plate and spaced closer to said periphery of said plate than said stud; said bend of each said stripper member being positioned between a respective said stud and its said retainer stud.
Claim 9
Dependent Claim
86 words
The rotary stripper of claim 2, wherein both said legs also engage said plate driving element as said legs pass by said plate driving element, such that the leading one of said legs of each said stripper member, while said stripper is rotating, extends adjacent to and is supported against excessive angular deflection by said plate driving element and the other trailing one of said legs of each said stripper member extends adjacent to and is supported against excessive angular deflection by one of said studs.
Claim 10
Dependent Claim
40 words
The rotary stripper of claim 8, wherein said stripper has three said studs and said legs of each said stripper member engage the said opposed surfaces of two adjacent said studs and said bend is on the third said stud.
Claim 11
Dependent Claim
83 words
The rotary stripper of claim 2, wherein said studs are uniformly spaced annularly around said plate driving element and are at equal radial distances from said plate driving element; said stripper members are interleaved with each other such that each successive said stripper member is laid atop the next preceding said stripper member in a stack thereof and successive said stripper members in said stack being mounted on annularly successive said studs, whereby said stripper members are uniformly arrayed annularly around said shaft.
Claim 12
Dependent Claim
37 words
The rotary stripper of any of claims 1, 2, 8 or 10, wherein each said stripper member leg is bent in the same direction to cause said leg to trail the direction of rotation of said stripper.
Claim 13
Dependent Claim
30 words
The rotary stripper of either claims 1, 2 or 10, further comprising a second plate over and attached on said studs, whereby said stripper members are captured between said plates.
Claim 14
Dependent Claim
58 words
The rotary stripper of claim 12, wherein said plate driving element comprises a socket upstanding from the first said plate; said plate driving element further comprising a drive shaft extending from outside said second plate and into said socket and being drivingly connected to said socket, whereby rotation of said drive shaft rotates said socket and said plates.
Claim 15
Dependent Claim
26 words
The rotary stripper of claim 4, further comprising a second plate over and attached on said studs, whereby said stripper members are captured between said plates.
Claim 16
Dependent Claim
58 words
The rotary stripper of claim 14, wherein said plate driving element comprises a socket upstanding from the first said plate; said plate driving element further comprising a drive shaft extending from outside said second plate and into said socket and being drivingly connected to said socket, whereby rotation of said drive shaft rotates said socket and said plates.
Claim 17
Dependent Claim
52 words
The rotary stripper of claim 10, wherein for each said stud, there is a respective retainer stud upstanding from said plate and spaced closer to said periphery of said plate than said stud; said bend of each said stripper member being positioned between a respective said stud and its said retainer stud.
