Abstract
Abstract A coupling arrangement for connecting a driving member to a driven member to transfer driving torque to the latter employs opposing wedge elements to lock the members together. The wedge elements function to provide large static clearances between the coupling arrangement and driven member upon their engagement and disengagement, enabling the driven member to be readily changed. At the same time, the wedge elements function to automatically take up the static clearance upon insertion of the driven member into the coupling arrangement, and, in addition, automatically compensate for dynamic clearances occurring during operation of the driven member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
A coupling arrangement for connecting a driving means to a driven means comprising: a. a coupling sleeve adapted at one end to be engaged by said driving means and having at the other end a socket for receiving a portion of the driven member, b. an outer wedge element slidably mounted along a surface within said socket for longitudinal movement inwardly and outwardly of said socket, c. means for continually urging said first wedge element outwardly of said socket, d. an inner wedge element slidably mounted on said outer wedge element for axial movement inwardly and outwardly of said socket, independently of and together with said outer wedge element, said inner wedge element having a surface for engaging a surface of the driven means, e. means continually urging said inner wedge element outwardly of said socket, and f. means as an integral part of said inner wedge element for engaging the driven means upon its insertion into said socket whereby such insertion causes said inner wedge element to be displaced inwardly of the socket against the urging of the means (e).
Claim 2
Dependent Claim
181 words
A coupling arrangement for connecting a driving means to a driven means comprising: a. a coupling sleeve adapted at one end to be engaged by said driving means and having at the other end a socket for receiving a portion of the driven member, b. an outer wedge element slidably mounted along a surface within said socket for longitudinal movement inwardly and outwardly of said socket, c. means for continually urging said first wedge element outwardly of said socket, d. an inner wedge element slidably mounted on said outer wedge element for axial movement inwardly and outwardly of said socket, independently of and together with said outer wedge element, said inner wedge element having a surface for engaging a surface of the driven means, e. means continually urging said inner wedge element outwardly of said socket, and f. means as an integral part of said inner wedge element for engaging the driven means upon its insertion into said socket whereby such insertion causes said inner wedge element to be displaced inwardly of the socket against the urging of the means (e).
Claim 3
Dependent Claim
47 words
The coupling arrangement of claim 1 wherein said inner and outer wedge elements comprise a first pair of wedge elements and the coupling arrangement includes a second like pair of wedge elements positioned within said socket at a location diametrically opposite the first pair of wedge elements.
Claim 4
Dependent Claim
32 words
The coupling arrangement of claim 2 wherein the outer wedge elements taper longitudinally from the inside of the socket and said inner wedge element taper longitudinally from the outside of the socket.
Claim 5
Dependent Claim
141 words
The coupling arrangement of claim 1 wherein means (c) comprises a compression spring which at one of its ends bears on the end of the outer wedge element innermost of the socket and at the other of its ends bears on a plate member forming the bottom of the socket, and means (e) comprises a rod member having a cylindrically shaped forepart and a cylindrically shaped back part of a smaller diameter than its forepart and being mounted for reciprocating motion within a recess in the wall of the sleeve coupling, the front of said forepart bearing against means (f), a second compression spring supported about the back part of said rod and bearing at one of its ends against the back of the forepart of said rod and at the other of its ends against the bottom of said recess.
Claim 6
Dependent Claim
55 words
The coupling arrangement of claim 4 in which the outer wedge element is slidably secured to the coupling sleeve and the inner wedge element is slidably secured to the outer wedge element by respective dovetail connections, and including stop means for limiting the longitudinal movement of the wedge elements inwardly and outwardly of the socket.
