Abstract
An apparatus for transporting or displacing elongated objects in a direction longitudinal to the object comprises a rotatable traction wheel including a first and a second disc. A plurality of arcuately shaped ridges are defined on opposing surfaces of the discs. The ridges extend substantially axially from the center of the discs to the circumferences of the discs. The first and second discs are journalled to a rotatable shaft. The axial and angular positions of one or both of the discs with respect to the shaft may be adjustable. The shaft may include an articulated joint to permit the angle of rotation of the first disc to be displaced from the angle of rotation of the second disc.
Claims16
An apparatus for longitudinally displacing elongated objects, comprising:
- means for defining a first axis of rotation;
- means for defining a second axis of rotation, said second axis of rotation intersecting said first axis of rotation at an angle, said first axis of rotation comprising a generatrix of a cone of revolution, said cone having a vertex at said intersection of said first and second axes, the top (apex) angle of said cone being equal to said angle between said first and second axes;
- a first disc rotatable about said first axis of rotation, said first disc including means for defining a first surface;
- a second disc rotatable about said second axis of rotation, said second disc including means of defining a second surface substantially opposing said first surface of said first;
- and
- means for rotating said generatrix about the axis of revolution of said cone.
An apparatus for longitudinally displacing elongated objects, comprising:
- a first shaft rotatable about a first axis of rotation;
- a second shaft having a second axis of rotation, said second axis of rotation intersecting said first axis of rotation at an angle, said second axis of rotation comprising a generatrix of a cone of revolution, said cone having a vertex at said intersection of said first and second axis, the top (apex) angle of said cone being equal to said angle between said first and second axes;
- a first disc secured to said first shaft, said first disc having a first, substantially conical surface;
- a second disc rotatable about said second axis of rotation, said second disc having a second substantially conical surface substantially opposing said first substantially conical surface of said first disc, said first and second substantially conical surfaces defining therebetween an interspace having a substantially V-shaped cross section and extending substantially circumferentially around said discs;
- means for rotating said first and second discs together;
- and
- means for rotating said second axis of rotation around the axis of revolution of said cone.
An apparatus for longitudinally displacing objects, comprising:
- a first shaft rotatable about a first axis of rotation;
- a first disc non-rotatably connected to said first shaft, said first disc including means for defining a first surface;
- a second shaft rotatable about a second axis of rotation;
- a second disc non-rotatably connected to said second shaft, said second disc including means for defining a second surface opposing said first surface of said first disc;
- first coupling means for coupling said first and second discs together to cause mutual rotation thereof, said first coupling means permitting angular displacement of said second axis of rotation with respect to said first axis of rotation;
- means for rotating said first shaft about said first axis of rotation;
- a third rotatable shaft;
- and
- second coupling means for coupling said third shaft to said second shaft, said second coupling means including means for rotating said second axis of rotation about an axis intersecting said first axis of rotation at an angle in response to rotation of said third shaft, said second coupling means including means for permitting said second shaft to rotate independently of the rotation of said third shaft.
