Abstract
Abstract The means flexibly or universally couple two members, that motion will be imparted from one to the other, and includes a first assembly which engages a portion of one member, and a second assembly which clamps the first assembly to the second member. An adapter is abuttingly interposed between surfaces of the two members; the adapter allows for universal movement of the members, and defines a slidable interface with a surface of one member. An annular plastic ring, disposed about the one member, resiliently constrains the latter against sliding across the adapter.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
281 words
Means for universally coupling first and second members together, for imparting movement from one of said members to the other thereof, comprising: a thrust block element; an adapter element; one of said elements having a convex surface formed thereon; and the other of said elements having a concave surface formed thereon; said elements having said surfaces in contacting engagement, defining a universally movable interface; said interfaced elements being interpositioned between said first and second members, effecting a continuous abutting engagement of surfaces of said members with surfaces of said elements; and a clamping assembly, engaging a portion of one of said members and fastened to the other of said members, clamping said elements and members together, locking said elements and members in continuous contacting and abutting engagement and preventing said elements and members from moving apart and separating from each other; wherein said clamping assembly includes a threaded sleeve, a plurality of rings enclosed by said sleeve and disposed about said portion of said one member, said one member having a surface deformation formed thereon and one of said rings is in engagement with said deformation, a lock nut threadedly engaged with said sleeve and forcefully clamping said rings together and locking said one ring against said surface deformation, and a resilient annulus radially interpositioned between said sleeve and another of said rings, said annulus having surfaces thereof in resiliently compressed engagement with surfaces of said sleeve and said another ring, resiliently limiting said one member in a slidable, radial movement only relative to said other member; said another ring encloses said one ring; and said plurality of rings includes a seat ring interpositioned between said another ring and said nut.

Means for universally coupling first and second members together, for imparting movement from one of said members to the other thereof, comprising: a thrust block element; an adapter element; one of said elements having a convex surface formed thereon; and the other of said elements having a concave surface formed thereon; said elements having said surfaces in contacting engagement, defining a universally movable interface; said interfaced elements being interpositioned between said first and second members, effecting a continuous abutting engagement of surfaces of said members with surfaces of said elements; and a clamping assembly, engaging a portion of one of said members and fastened to the other of said members, clamping said elements and members together, locking said elements and members in continuous contacting and abutting engagement and preventing said elements and members from moving apart and separating from each other; wherein said clamping assembly includes a threaded sleeve, a plurality of rings enclosed by said sleeve and disposed about said portion of said one member, said one member having a surface deformation formed thereon and one of said rings is in engagement with said deformation, a lock nut threadedly engaged with said sleeve and forcefully clamping said rings together and locking said one ring against said surface deformation, and a resilient annulus radially interpositioned between said sleeve and another of said rings, said annulus having surfaces thereof in resiliently compressed engagement with surfaces of said sleeve and said another ring, resiliently limiting said one member in a slidable, radial movement only relative to said other member; said another ring encloses said one ring; and said plurality of rings includes a seat ring interpositioned between said another ring and said nut.
Claim 3
Dependent Claim
36 words
Coupling means, according to claim 1, wherein: said one ring comprises a split collar; said another ring comprises a generally cup-shaped guide ring having an annular wall; and said split collar is enclosed by said wall.
Claim 4
Dependent Claim
40 words
Coupling means, according to claim 1, wherein: said another ring comprises a guide ring having an annular, convex surface; said seat ring has an annular concave surface; said convex and concave surfaces of said rings are in interfaced, contacting engagement.
Claim 5
Dependent Claim
13 words
Coupling means, according to claim 2, wherein: said resilient annulus envelops said wall.
