Abstract: Apparatus for converting rotary motion to linear motion and/or linear motion to rotary motion, comprising: a rotatable piece (24) having a surface, the piece being rotatable about an axis thereof; at least one member (26a-d) having a linking surface (44a-d) facing the surface of the rotatable piece and arranged for restricted movement at least in part laterally relative to the axis of the piece; and located between the surface of the rotatable piece and the or each reciprocating member, means for linking the linking surface of the respective member and the surface of the rotatable piece, wherein the means for linking (30a-d), the surface of the rotatable piece and the linking surface are configured to cooperate so that rotational motion of the rotatable piece causes linear movement of the at least one member, and/or linear movement of the at least one member causes rotational motion of the rotatable piece.

Abstract: Apparatus for converting between rotary motion and linear motion includes a rotatable piece being rotatable about an axis; at least one member having a linking surface facing the rotatable piece and arranged for movement relative to the axis of the piece; and a means for linking the linking surface of the respective member and the surface of the rotatable piece, so that rotational motion of the rotatable piece causes linear movement of the at least one member, and/or linear movement of the at least one member causes rotational motion of the rotatable piece. A sawing device may include said apparatus for cutting by repetitive reciprocating cutting action. A saw blade may be configured for such a sawing device.
