Abstract
A coping saw is provided having two spaced-apart rotary actuators supported by a frame. Two saw-blade sections extend between the two rotary actuators and are intended to singularly engage a work piece. The saw is adapted to contain a drive mechanism which is coupled to a first of the two rotary actuators for causing the saw-blade sections to move in at least one direction. At least one guide roller assembly is disposed adjacent each of the two saw-blade sections for providing stability and retaining said two-saw blade sections between said two rotary actuators.
Claims21
A saw, comprising in combination
- a frame assembly having a first and a second end;
- a drive pulley journaled to said frame assembly;
- a driven pulley journaled to said frame assembly;
- a continuous loop blade extending at least partially around said drive pulley and said driven pulley to provide two cutting blade segments;
- and
- at least one anti back-out bearing intermediate said drive and driven pulleys for maintaining said continuous loop blade on said drive and driven pulleys.
A method for manufacturing a powered coping saw, comprising the steps of:
- providing a frame assembly having a first and second end;
- journaling a drive pulley and a driven pulley to said frame assembly;
- mounting a continuous loop blade between said drive pulley and said driven pulley to define two parallel intermediate blade sections;
- and
- providing at least one anti back-out bearing assembly proximate at least one of said two parallel intermediate blade sections.
A coping saw, comprising:
- a frame assembly
- a drive pulley journaled to one end of said frame assembly;
- a driven pulley journaled to an opposite end of said frame assembly
- a saw blade looped at least partially around said drive and driven pulleys, said saw blade having a cutting surface providing two generally parallel cutting segments;
- and
- at least one anti back-out bearing assembly mounted to said frame assembly and disposed adjacent said cutting surface of said saw blade.
