Abstract
An apparatus for imparting a simultaneous rotational movement to an object moving along a rectilinear trajectory a slide block can be moved to and fro along a substantially cylindrical rod that has at least one flattened surface that is engaged by a guide wheel journalled in the slide surface block. The flattened surface extends partially rectilinearly and partially spirally along the cylindrical rod.
Claims7
Apparatus for guiding an object for rotational and rectilinear movement, comprising:
- (a) an elongated slide block having an elongated cylindrical opening extending through said slide block;
- (b) a rigid guide rod extending through said cylindrical opening, having at least one flattened surface extending along the surface of a first section of said guide rod parallel to the longitudinal axis of said guide rod and at an angle to said longitudinal axis along a second section of said guide rod;
- (c) bearing means to support said slide block for rectilinear movement along said guide rod and for rotational movement about said guide rod;
- and
- (d) means on said slide block for supporting at least one guide wheel for rolling contact with said flattened surface on said guide rod, whereby rectilinear movement of said slide block along said guide rod will cause said slide block to move in a rectilinear path along said first section of said guide rod and in a rotational and rectilinear path along said second section of said guide rod.
