Abstract
Abstract A device for mounting on a machine to allow the machine to be used as a saw comprises a member for securing to the machine. A tension spring is connected to one extremity of said member, the other end of the tension spring connected to one end of a saw blade or wire. The device comprises also means connected to the other end of the saw blade or wire and for connection to a spindle of a motor of a machine and for converting rotary motion of the spindle to reciprocating rectilinear motion and imparting the reciprocating rectilinear motion to the saw blade or wire.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
96 words
A power driven jig saw comprising a saw wire, a tension spring secured to one end of the saw wire, power means connected to the other end of the saw wire to reciprocate the saw wire against the tension of the tension spring, the tension spring being secured to the saw wire at one end of the tension spring, and means for selectively fixing the other end of the tension spring in any of a plurality of adjusted positions of rotation of said other end of the tension spring about the axis of the tension spring.
Claim 2
Dependent Claim
96 words
A power driven jig saw comprising a saw wire, a tension spring secured to one end of the saw wire, power means connected to the other end of the saw wire to reciprocate the saw wire against the tension of the tension spring, the tension spring being secured to the saw wire at one end of the tension spring, and means for selectively fixing the other end of the tension spring in any of a plurality of adjusted positions of rotation of said other end of the tension spring about the axis of the tension spring.
Claim 3
Dependent Claim
56 words
A jig saw as claimed in claim 1, said fixing means comprising a rod to one end of which said other end of said tension spring is secured, and means for releasably clamping said rod to a fixed member in any of a plurality of positions of rotation of said rod about the axis said rod.
Claim 4
Dependent Claim
37 words
A jig saw as claimed in claim 2, said clamping means comprising a flange on said rod and a nut screwthreadedly received on said rod for releasably clamping said fixed member between said nut and said flange.
Claim 5
Dependent Claim
