Abstract

Abstract The wheel comprises a pad-mounting structure constituted by an axially spaced series of split circular disc-like plate units of aluminum which are coaxially and releasably clamped rigidly to a wheel driving shaft at the ends and between the ends of said structure. Each such plate component is comprised of two substantially identical semi-circular plate halves which directly clamp releasably to the shaft, the plate pairs at axial ends of the assembly each being supplemented by a further similar split plate or disc unit located just axially inward thereof. All except the two endmost of said split plate units are provided with an annular series of equally spaced holes closely adjacent their outer periphery, which holes slidably receive elongated rods paralleling the shaft axis, upon which axially aligned sets of flexible finishing pads or packs of the wheel are mounted for a very free-swinging action. However, the endmost plates are imperforate in said peripheral zone; and either one or both halves of an endmost plate unit may be taken off the wheel shaft if the finishing pad is to be removed and replaced, as accommodated by an axial sliding movement of a pivot rod. Each half of each split plate unit is provided at its diametral zone with a thickened axial boss or hub formation presenting a semicylindrical seat; and said seats center on the wheel shaft when said halves are releasably bolted to the shaft at said bosses thereof.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 111 words
A rotary wheel structure to mount radially outer finishing units, comprising a series of axially spaced split opposite end and intermediate plate units each including two generally similar, semi-circular plates in substantial radial register and having means to releasably clamp the same coaxially in a partially surrounding relation to a drive shaft, there being two of said split end units adjacent each of the ends of said shaft, the axially inner end and intermediate plates of said plate units, as thus clamped, each having means spaced radially outwardly of the axis of said shaft for pivotally mounting said finishing units in circumferentially spaced relation to one another about said shaft axis.
Claim 2
Dependent Claim 111 words
A rotary wheel structure to mount radially outer finishing units, comprising a series of axially spaced split opposite end and intermediate plate units each including two generally similar, semi-circular plates in substantial radial register and having means to releasably clamp the same coaxially in a partially surrounding relation to a drive shaft, there being two of said split end units adjacent each of the ends of said shaft, the axially inner end and intermediate plates of said plate units, as thus clamped, each having means spaced radially outwardly of the axis of said shaft for pivotally mounting said finishing units in circumferentially spaced relation to one another about said shaft axis.
Claim 3
Dependent Claim 111 words
A rotary wheel structure to mount radially outer finishing units, comprising a series of axially spaced split opposite end and intermediate plate units each including two generally similar, semi-circular plates in substantial radial register and having means to releasably clamp the same coaxially in a partially surrounding relation to a drive shaft, there being two of said split end units adjacent each of the ends of said shaft, the axially inner end and intermediate plates of said plate units, as thus clamped, each having means spaced radially outwardly of the axis of said shaft for pivotally mounting said finishing units in circumferentially spaced relation to one another about said shaft axis.
Claim 4
Dependent Claim 111 words
A rotary wheel structure to mount radially outer finishing units, comprising a series of axially spaced split opposite end and intermediate plate units each including two generally similar, semi-circular plates in substantial radial register and having means to releasably clamp the same coaxially in a partially surrounding relation to a drive shaft, there being two of said split end units adjacent each of the ends of said shaft, the axially inner end and intermediate plates of said plate units, as thus clamped, each having means spaced radially outwardly of the axis of said shaft for pivotally mounting said finishing units in circumferentially spaced relation to one another about said shaft axis.
Claim 5
Dependent Claim 59 words
The wheel structure of claim 1, in which said plates each have a radially inner seat adjacent its diameter at which it is releasably clamped to said drive shaft, said pivotal mounting means comprising a plurality of elongated rods paralleling the shaft axis and received in a circumferentially spaced series of holes in said plates which surround said axis.
Claim 6
Dependent Claim 65 words
The wheel structure of claim 2, in which said end and intermediate plate units are in substance the same save that the axially outer plates of the opposite end plate units lack rod-receiving holes in a circumferential zone thereof radially coinciding with the zone of said series, thereby to axially end-confine rods slidably guided in said holes of other plates of said split plate units.
Claim 7
Dependent Claim 41 words
The wheel structure of claim 2, in which said plates are provided at the respective diameters thereof with axially enlarged bosses affording seats which partially encircle said shaft, and means at said bosses to releasably clamp said plates to the shaft.
Claim 8
Dependent Claim 41 words
The wheel structure of claim 3, in which said plates are provided at the respective diameters thereof with axially enlarged bosses affording seats which partially encircle said shaft, and means at said bosses to releasably clamp said plates to the shaft.
Claim 9
Dependent Claim 87 words
A combined assembly of the wheel structure as defined in claim 2 with a circumferentially spaced array of said finishing units as pivotally mounted on said plate rods of said units, said finishing units each comprising a number of like flexible sheets slitted uniformly along spaced longitudinal lines, and a clip mounting said sheets at ends thereof spaced from said lines in a unitary multiple sheet stack, said clip being provided adjacent a radially inner portion thereof with means connecting the clip to one of said rods.
