Abstract
Abstract The rotary flap or finishing wheel or tool has a plurality of radially extending finishing units or packs mounted in a circumferential series on a hub structure. The finishing units or packs are each pivotally mounted on the body structure by a dual clip-type assembly including an inner axially elongated and rigid pivoting clip member forming the primary component of the pack and an outer axially elongated clamping or clip member supporting or carrying the finishing or fill material and forming the secondary component of the pack. The pivotal mount of the inner clip member is afforded at an inner axially extending keyholetype opening of the clip or at an axial through-bore, either of which formations at least partially encircles and is adapted to pivot on an axial pin component located adjacent the outer periphery of the hub structure. At a point radially outwardly of its pivot pin bore, as well as of the outer periphery of the hub structure, the inner clip member has an axially slidable, dovetail or tongue-and-groove type connection to the aforementioned secondary, radially outwardly exposed outer clip or clamping member which, like the inner clip member, extends the entire axial length of the pack. The outer clamping member has a pair of radial arms which receives the fill or finishing material therebetween. In any one of a number of versions of dove-tail, tongue-and-groove, or keyhole type connections between the primary inner clip member and the secondary outer clip member, the latter is slidably assembled on, and removable from, the former to permit a ready installation and replacement of the secondary clip member in relation to the primary clip member and the hub structure.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
93 words
A pack adapted to be mounted on a rotary wheel hub structure, comprising a radially extending inner clip member having means to pivotally engage the same with the hub structure to swing individually on an axis paralleling the rotative axis of the hub structure, a unit of finishing material, and mounting means slidably engaging said clip member to mount said unit of finishing material on said clip member for assembly, removal and replacement in relation to the latter and the hub structure, without requiring removal of said clip member from the hub structure.
Claim 2
Dependent Claim
93 words
A pack adapted to be mounted on a rotary wheel hub structure, comprising a radially extending inner clip member having means to pivotally engage the same with the hub structure to swing individually on an axis paralleling the rotative axis of the hub structure, a unit of finishing material, and mounting means slidably engaging said clip member to mount said unit of finishing material on said clip member for assembly, removal and replacement in relation to the latter and the hub structure, without requiring removal of said clip member from the hub structure.
Claim 3
Dependent Claim
66 words
The pack of claim 1, in which said inner clip member has a pivot portion engageable with a pivot part of the hub structure which parallels the latter''s rotative axis, and a formation also paralleling said axis, said mounting means comprising a clamping member for said unit of finishing material having a formation in mated, axially sliding engagement with said formation of the inner clip member.
Claim 4
Dependent Claim
20 words
The pack of claim 2, in which said clamping member has said mated formation adjacent a radially inner portion thereof.
Claim 5
Dependent Claim
21 words
The pack of claim 3, in which said formations of said members have tongue-and-groove type, slidable mating engagement with one another.
Claim 6
Dependent Claim
37 words
The pack of claim 2, in which said pivot portion of said inner clip member has a keyhole-type formation adjacent a radially inner end of the member to pivotally engage said pivot part of the hub structure.
Claim 7
Dependent Claim
37 words
The pack of claim 4, in which said pivot portion of said inner clip member has a keyhole-type formation adjacent a radially inner end of the member to pivotally engage said pivot part of the hub structure.
Claim 8
Dependent Claim
40 words
The pack of claim 2, in which said pivot portion of said inner clip member has an axial through-bore wholly surrounded by the material of said pivot portion and adapted to pivotally engage said pivot part of the hub structure.
Claim 9
Dependent Claim
40 words
The pack of claim 4, in which said pivot portion of said inner clip member has an axial through-bore wholly surrounded by the material of said pivot portion and adapted to pivotally engage said pivot part of the hub structure.
Claim 10
Dependent Claim
27 words
The pack of claim 6, in which a slot portion of said keyhole-type formation opens radially outwardly to the groove portion of a formation mating said members.
Claim 11
Dependent Claim
22 words
The pack of claim 4, in which the groove portion of a formation mating said members is on said inner clip member.
Claim 12
Dependent Claim
17 words
The pack of claim 9, in which said formation-mating groove portion is on said inner clip member.
Claim 13
Dependent Claim
21 words
The pack of claim 4, in which the groove portion of a formation mating said members is on said clamping member.
Claim 14
Dependent Claim
16 words
The pack of claim 9, in which said formation-mating groove portion is on said clamping member.
Claim 15
Dependent Claim
264 words
A pack adapted to be mounted on a rotary hub structure having a rotative axis with said pack extending radially outward of the axis, comprising a radially extending elongated Inner clip member having means adapted to mount the same on the hub structure parallel to the rotative axis of the hub structure, a flap-like member of fill material presenting a radially outer portion adapted to engage a workpiece, and elongated mounting means including on the inner portion thereof means slidably engaging said inner clip member to mount said flap-like member of fill material on said inner clip member for assembly, removal and replacement in relation to the latter and the hub structure, without requring removal of said inner clip member from the hub structure, said mounting means having a length generally corresponding to the axial length of said elongated inner clip member, said mounting means having a radially outer and outwardly extending portion integral with said inner portion and coextensive thereith in overall axial length, to which outwardly extending portion a radially inner portion of said flap-like member is fixedly secured, said mounting means being movable relative to said inner clip member in a direction parallel to the rotative axis of the hub structure to effect said assembly, removal and replacement with respect to said inner clip member, said inner clip member including a formation, said mounting means including a formation in mated, axially sliding engagement with said formation on said inner clip member thus preventing movement of said mounting means in a direction other than parallel to the axis of the hub structure.
Claim 16
Dependent Claim
264 words
A pack adapted to be mounted on a rotary hub structure having a rotative axis with said pack extending radially outward of the axis, comprising a radially extending elongated Inner clip member having means adapted to mount the same on the hub structure parallel to the rotative axis of the hub structure, a flap-like member of fill material presenting a radially outer portion adapted to engage a workpiece, and elongated mounting means including on the inner portion thereof means slidably engaging said inner clip member to mount said flap-like member of fill material on said inner clip member for assembly, removal and replacement in relation to the latter and the hub structure, without requring removal of said inner clip member from the hub structure, said mounting means having a length generally corresponding to the axial length of said elongated inner clip member, said mounting means having a radially outer and outwardly extending portion integral with said inner portion and coextensive thereith in overall axial length, to which outwardly extending portion a radially inner portion of said flap-like member is fixedly secured, said mounting means being movable relative to said inner clip member in a direction parallel to the rotative axis of the hub structure to effect said assembly, removal and replacement with respect to said inner clip member, said inner clip member including a formation, said mounting means including a formation in mated, axially sliding engagement with said formation on said inner clip member thus preventing movement of said mounting means in a direction other than parallel to the axis of the hub structure.
