Abstract
An arcuate action tool attachment is adapted to receive an input and to convert that input into reciprocating output motion along an arcuate path. The tool may be adapted to be combined with an existing linear reciprocating device or a rotary device, or the tool may comprise a single unit including a linear reciprocating device or a rotary device. The tool may be fitted with one or more curved or arc-shaped accessories, such as saw blades or the like, that reciprocate along the arcuate paths that may have substantially the same radius of curvature as the accessory.
Claims31
A reciprocating tool adapted to reciprocally drive at least one accessory along an arcuate path, said tool comprising:
- a drive input member, said drive input member adapted to receive a drive input;
- an arcuate converting mechanism attached to said drive input member and having an accessory holder, said arcuate converting mechanism converting said drive input into arcuate reciprocating movement of said accessory holder;
- and
- at least one accessory mounted to said accessory holder and reciprocally movable in an arcuate path via said arcuate converting mechanism.
An attachment for converting a drive input from a powered drive device into an arcuate output path, said attachment comprising:
- a mounting portion for mounting said attachment to the powered drive device;
- a converting mechanism for converting said drive input from the powered drive device to an arcuate reciprocating motion of an accessory along the arcuate output path;
- and
- an accessory holder for mounting an accessory thereto, said accessory holder being movable along the arcuate output path via said converting mechanism when said attachment is mounted to the drive device and when the drive device is actuated to generate said drive input.
The attachment of claim 19, wherein said converting mechanism comprises at least one connecting link pivotally mounted between said accessory holder and a drive input member of the powered drive device, said converting mechanism further comprising a curved rod, and at least one guide element for guiding said curved rod along said arcuate path.
A method of fabricating an arcuate saw blade having a cutting edge, a non-cutting edge, and a mounting portion, said method comprising:
- providing a circular blank;
- providing a cutting apparatus;
- positioning said circular blank at said cutting apparatus;
- cutting said mounting portion with said cutting apparatus;
- and
- cutting at least one of said cutting edge and said non-cutting edge from said circular blank with said cutting apparatus to form at least two arcuate saw blades from said circular blank.
A reciprocating tool comprising:
- a reciprocating mechanism;
- and
- an accessory having a mounting portion and a working portion, said mounting portion being substantially offset from said working portion and said working portion having an extension extending from said mounting portion toward said reciprocating mechanism, wherein said accessory is reciprocally drivable by said reciprocating mechanism such that each of said mounting portion and said working portion reciprocates linearly along substantially spaced parallel paths.
A method of fabricating a saw blade, said method comprising:
- providing a base member having a first plurality of protrusions for interlocking engagement;
- providing a blade member having a cutting portion comprising teeth and a second plurality of protrusions for interlocking engagement with said first plurality of protrusions;
- and
- interlocking said first plurality of protrusions with said second plurality of protrusions.
A reciprocating tool adapted to reciprocally drive at least one accessory, said tool comprising:
- a reciprocating mechanism;
- an accessory;
- said accessory being reciprocally drivable by said reciprocating mechanism;
- and
- at least two user inputs, wherein said reciprocating mechanism is selectively actuatable via said at least two user inputs so that said reciprocating tool is usable in different orientations.
