Abstract
Abstract A mechanism for transforming a translation movement into a rotation movement which is then followed by a translation movement comprising a first member which can be a control member slidable on a smooth shaft and constituted by a hollow cylinder coaxial with the shaft, and terminated by two planar symmetrical faces which are inclined with respect to the shaft, and a second member which can be a driven member and fixed to the shaft. The second member is constituted by two hollow cylinders coaxial with the shaft and of the same diameter as the control member. Each hollow cylinder terminates with a planar face having the same inclination with the shaft as the faces of the control member, the planar faces of the hollow cylinders being in contact with respective faces of the control member. The two planar faces of the driven member are angularly offset relative to one another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A mechanism for transforming a translation movement into a rotation movement followed by a translation movement, said mechanism comprising a smooth shaft, a first member slidably mounted on said shaft, said first member being constituted by a hollow cylinder coaxial with said shaft, and having two end faces which are planar and symmetrical and form an angle of inclination with respect to said shaft, and a second member fixed to said shaft and constituted by two cylinders coaxial with said shaft, each cylinder of the second member having a planar face of the same inclination with respect to said shaft as said end faces of the first member, each planar face of the cylinders of the second member facing a respective inclined planar face of the first member for contacting the same, said two planar faces of the hollow cylinders member being angularly offset with respect to one another.
Claim 2
Dependent Claim
149 words
A mechanism for transforming a translation movement into a rotation movement followed by a translation movement, said mechanism comprising a smooth shaft, a first member slidably mounted on said shaft, said first member being constituted by a hollow cylinder coaxial with said shaft, and having two end faces which are planar and symmetrical and form an angle of inclination with respect to said shaft, and a second member fixed to said shaft and constituted by two cylinders coaxial with said shaft, each cylinder of the second member having a planar face of the same inclination with respect to said shaft as said end faces of the first member, each planar face of the cylinders of the second member facing a respective inclined planar face of the first member for contacting the same, said two planar faces of the hollow cylinders member being angularly offset with respect to one another.
Claim 3
Dependent Claim
14 words
A mechanism according to claim 1, having a pivoting movement around a transverse axis.
Claim 4
Dependent Claim
61 words
A mechanism according to claim 1 for locking and unlocking the jaws of a machine wherein the jaws are mounted at the end of said shaft, a clamp member being fixed to said first member, spring means acting on said shaft in a direction to release the jaws and means for tightening the jaws by applying tension on the clamp member.
Claim 5
Dependent Claim
60 words
A mechanism according to claim 1 for locking and unlocking the jaws of a machine wherein the jaws are mounted at the end of said shaft, means fixedly securing said first member, spring means for yieldably securing said second member and clamp means supported on said second member for releasing the jaws by application of pressure on said clamp means.
Claim 6
Dependent Claim
18 words
A mechanism according to claim 1 wherein said cylinders of said second member are angularly offset by 90°.
Claim 7
Dependent Claim
19 words
A mechanism according to claim 1 wherein the cylinders of the first and second members have the same diameter.
Claim 8
Dependent Claim
180 words
A mechanism according to claim 1 wherein said cylinder of the first member is interposed between the cylinders of the second member such that the planar face of a first of the cylinders of the second member is aligned with the facing planar surface of the cylinder of the first member while the planar face of the second of the cylinders of the second member is angularly offset from the facing planar surface of the clyinder of the first member such that when the cylinder of the first member is slidably moved in one direction, the planar face thereof which is angularly offset from the facing surface of said second cylinder of the second member contacts said face to cause said second cylinder of the second member to be rotated which produces rotation of the shaft in one direction resulting in rotation of the first cylinder by an equal amount, slidable movement of the cylinder of the first member in the opposite direction producing rotation of the first cylinder of the second member in reverse direction to its original position.
