  "abstract": "The peripheral fittings for resolving sliver are carried by an annular sleeve. Such sleeve is removably mounted concentrically of the resolving roller shaft by a centering roller body carried by the shaft. A resilient member is radially spread by a clamping ring to frictionally interconnect the roller body and the fittings sleeve for maintaining the sleeve in desired axial relationship and for transmitting force from the shaft and roller body to the peripheral fittings to effect conjoint rotation.",
  "claims": [
    "1. A resolving roller comprising: a fittings sleeve; a roller body for carrying said fittings sleeve which roller body has a generally radial riser portion; drive means for rotating said roller body; a clamping member connectible with said roller body for conjoint rotation therewith, said clamping member including a generally radial portion spaced from said roller body riser portion for forming therewith a resilient means-receiving cavity and an outer circumferential surface for receiving said fittings sleeve; means for connecting said roller body and said clamping member and for effecting adjustment of the axial width of said resilient means-receiving cavity; and resilient means in said resilient means-receiving cavity for effecting radial expansion by adjustment of the axial width of said cavity and for holding said fittings sleeve on said roller body for conjoint rotation therewith.",

    "3. The resolving roller defined in claim 2, in which the resilient means is made of elastomeric material.",
    "4. The resolving roller defined in claim 2, in which the resilient means includes a Belleville spring.",
    "5. The resolving roller defined in claim 2, in which the cavity has an inner axial side formed by a circumferential portion of the roller body.",
    "6. The resolving roller defined in claim 5, in which the inner axial side of the cavity is substantially frustoconically tapered toward the clamping member.",
    "7. The resolving roller defined in claim 6, in which the interior margin of the clamping member adjacent to the inner axial side of the cavity is cutaway.",
    "8. The resolving roller defined in claim 5, in which the roller body is stepped and includes a first circumferential portion having a radius slightly less than the interior radius of the fittings sleeve and a second circumferential portion having a radius less than the radius of said first circumferential portion, said second circumferential portion forming the cavity inner axial side.",
    "9. The resolving roller defined in claim 8, in which the axial extent of the resilient means is less than the axial extent of the roller body second circumferential portion, and the clamping member portion adjacent to the roller body riser portion is ring shaped, said ring shaped clamping member portion being substantially circumferentially engaged with the roller body second circumferential portion and being centered thereby relative to the roller axis.",
    "10. The resolving roller defined in claim 9, the roller body having a stepped hub including a threaded portion and a reduced portion at the side of said threaded portion remote from the resilient means, the clamping member having a first internally threaded portion threadedly connectible with said hub threaded portion and a second threaded portion substantially concentric with and radially spaced from said hub reduced portion, and a locknut receivable between the clamping member and said hub reduced portion and threadedly connectible with said clamping ring second threaded portion.",
    "11. The resolving roller defined in claim 2, in which the resilient means is ring shaped and is loosely received in the cavity and unattached to any cavity side.",
    "12. The resolving roller defined in claim 2, in which the clamping member end portion remote from the resilient means has a substantially cylindrical surface and the opposite end portion is substantially frustoconically tapered toward the resilient means, the clamping member being slidably insertible axially into the fittings sleeve with its tapered end portion leading.",
    "13. The resolving roller defined in claim 2, in which the roller body end remote from the clamping member carries a radial flange stop engageable by an edge of the fittings sleeve.",
    "14. The resolving roller defined in claim 2, in which the clamping member end remote from the resilient means carries a radial flange shielding an edge of the fittings sleeve.",
    "15. The resolving roller defined in claim 14, in which the clamping member radial flange includes an annular groove in its side adjacent to the fittings sleeve, said groove having inner and outer radii of an extent such that the adjacent fittings sleeve end margin is receivable in said groove.",
    "16. The resolving roller defined in claim 2, and a shaft connecting the roller and the drive means, said shaft extending through the roller and having an end substantially flush with the roller end, said shaft end having a bore, and gripping means receivable in said shaft end bore for pulling the roller and shaft apart from the drive means.",
    "17. The resolving roller defined in claim 16, in which the shaft end bore is threaded, and the gripping means is a handle threadedly insertible in the shaft end bore."

  "description_excerpt": "1. Field of the Invention\n\nThe present invention relates to a composite resolving roller having exchangeable fittings carried by a roller body and secured by a clamping ring threadedly connected to the roller body.\n\n2. Prior Art\n\nBecause the sets of resolving rollers for open end spinning machines are heavily used during resolving of fiber sliver, the fittings are subjected to an extremely high rate of wear. Therefore, the resolving rollers must be replaced periodically.\n\nIn order to avoid replacement of the entire resolving roller, fittings have been provided on sleeves which can slide onto a roller body, and a clamping disk is screwed onto the body to hold the sleeve in place. (Japanese Utility Model Publication No. 2913/73).\n\nSuch prior construction has not eliminated the problem of special machining upon exchange of fittings. Because it is necessary to have very close tolerances between the resolving roller ends and the corresponding walls of the roller housing for such technological reasons as maintaining fiber-directing air currents and avoiding spaces in which fiber can lodge, it has been necessary to grind the roller ends. Such grinding has been necessary both upon initial installation and upon each exchange of fittings. Since repeated grinding reduces the roller size, the roller body, or at least the clamping disk, must be replaced frequently. It is also necessary to utilize skilled technicians and special tools for each fittings change.",
