Abstract
Abstract This invention concerns an elastic coupling suitable for transmitting drive to a machine tool and comprising two series of generally radially extending spring strip elements, e.g. of spring steel laminate construction, anchor means for anchoring radially inner and outer portions of each spring strip element of each series so as to be sprung and inclined circumferentially to the radius, the spring strip elements of one series being inclined in an opposite circumferential sense to the spring strip elements of the other series and drive input and output means arranged such that drive is transmitted via the spring strip elements.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
An elastic coupling suitable for transmitting drive to a machine tool comprising a drive input means, a drive output means, one of said drive means including a pair of annular collars, two series of generally radially extending spring strip elements, one collar anchoring the radially outer portions of the spring strip elements of one series and the other collar anchoring the radially outer portions of the spring strip elements of the other series, said other drive means being adapted to anchor the radially inner portions of the spring strip elements of both series, said sPring strip elements being inclined circumferentially to the radius with the spring strip elements of one series being inclined in an opposite sense to the spring strip elements of the other series, said drive input means and said drive out-put means being arranged so that the drive is transmitted through the spring strip elements to tend to cause a change in the inclination thereof to the radius, and means to rotatably adjust one collar with respect to the other collar to vary the inclination of the two series of spring strip elements with respect to each other and thus vary the elasticity constant of the coupling.
Claim 2
Dependent Claim
200 words
An elastic coupling suitable for transmitting drive to a machine tool comprising a drive input means, a drive output means, one of said drive means including a pair of annular collars, two series of generally radially extending spring strip elements, one collar anchoring the radially outer portions of the spring strip elements of one series and the other collar anchoring the radially outer portions of the spring strip elements of the other series, said other drive means being adapted to anchor the radially inner portions of the spring strip elements of both series, said sPring strip elements being inclined circumferentially to the radius with the spring strip elements of one series being inclined in an opposite sense to the spring strip elements of the other series, said drive input means and said drive out-put means being arranged so that the drive is transmitted through the spring strip elements to tend to cause a change in the inclination thereof to the radius, and means to rotatably adjust one collar with respect to the other collar to vary the inclination of the two series of spring strip elements with respect to each other and thus vary the elasticity constant of the coupling.
Claim 3
Dependent Claim
68 words
The coupling of claim 10 wherein one of the annular collars is fixed, the second being controllably movable axially with respect to the first, collar rotation means being provided associated with each collar such that on movement of the second annular collar axially towards the first, said second collar is caused simultaneously to rotate with respect to the first to alter the inclination of the spring strip elements.
Claim 4
Dependent Claim
37 words
The coupling of claim 4 wherein said collar rotation means comprises a wedge-shaped extension piece on one collar cooperating with a congruous shaped recess on the other collar, the extension piece being circumferentially offset from the recess.
Claim 5
Dependent Claim
56 words
The coupling of claim 10 wherein the radially outer portion of each spring strip element is provided with an axially projecting ear, and each collar is provided with a series of radially extending slots of inverted ''''L'''' form to accommodate and anchor the radially outer portions of the spring strip elements including said axially projecting ears.
