ABSTRACT:
A sabre saw comprises a saw blade connected at its rear end to an elongated saw blade carrier extending in the longitudinal direction of the blade. The carrier is guided for reciprocating movement in a bushing which is mounted in the housing of the sabre saw for pivotal movement about a pivot axis normal to the longitudinal direction of the carrier. A first bevel gear driven by a second bevel gear on the output of an electric motor is rotated about its axis inclined at an acute angle to the longitudinal direction of the carrier and carrying a pin parallel to and laterally spaced from the inclined axis. The pin projects with a free end portion into a yoke fixed to the bottom face of the carrier and at least one spring cooperates with a member fixed to the bushing and projecting rearwardly therefrom substantially parallel to the carrier to maintain the end portion of the pin within the yoke during orbiting of the pin, so that the carrier and the saw blade carried thereon will make during operation of the motor a reciprocating movement in longitudinal direction and a pivotal movement about the pivot axis.
