摘要： 57 A reciprocating saw is provided with a vertical blade (1) controlled by interconnected blade carrier arms (2,2') moved by an eccentric mechanism. The blade (1) is pivotally connected at its ends to upper and lower blade carrier arms (2,2') which are themselves pivoted, by means of suitable shaped spacers (3), to the side walls of a support frame (4) similar in form to a bow for fretwork. The support frame (4) carries, at its closed end, a first pulley (5) on a fixed axis and a second pulley (6) pivoted to one arm of a beltcrank lever (7) the other arm of which is biased by a spring (8) secured to the support frame itself by means of a peg (9). One end of a drive rod (10) is pivotally connected to the lower blade-carrier arm (2') and the upper blade-carrier arm is connected to an inextensible line (13) which passes over the pulleys and leads to an oscillatable drive arm to which the other end of the drive rod is connected.
