Abstract
A stapler includes a base, a cover coupled to the base, a driver for driving a leading staple from a supply of staples into a workpiece, a handle constructed and arranged to actuate the driver and move the cover towards the base, and a cutting assembly. The cutting assembly includes a pair of benders constructed and arranged to engage and bend the legs of the leading staple, a stationary cutter, and a pair of movable cutters that interact with the stationary cutter to cut an excess length of each of the legs of the staple. Movement of the cover towards the base causes the movable cutters to move towards the stationary cutter.

A stapler comprising:
- a base;
- a cover coupled to the base;
- a driver for driving a leading staple from a supply of staples into a workpiece, with each staple having first and second legs;
- a handle constructed and arranged to actuate the driver and move the cover towards the base;
- and
- a cutting assembly comprising:
- a pair of benders constructed and arranged to engage and bend the first and second legs of the leading staple;
- a stationary cutter;
- and
- first and second independently movable cutters that independently interact with the stationary cutter to cut an excess length of each of the first and second legs of the staple, wherein movement of the cover towards the base causes the first and second independently movable cutters to move towards the stationary cutter.
A stapler comprising:
- a base;
- a cover coupled to the base;
- a driver for driving a leading staple from a supply of staples into a workpiece, with each staple having first and second legs;
- a handle constructed and arranged to actuate the driver and move the cover towards the base;
- and
- a cutting assembly comprising:
- a pair of benders constructed and arranged to engage and bend the first and second legs of the leading staple;
- a stationary cutter;
- a pair of movable cutters that interact with the stationary cutter to cut an excess length of each of the first and second lees of the staples wherein movement of the cover towards the base causes the movable cutters to move towards the stationary cutter;
- and
- a housing substantially enclosing the benders, the stationary cutter and the pair of movable cutters, wherein the housing comprises two shells attached to each other, wherein each of the shells defines a groove, and wherein each of the movable cutters comprises a slide for sliding in one of the grooves.
A stapler comprising:
- a base;
- a cover coupled to the base;
- a driver for driving a leading staple from a supply of staples into a workpiece, with each staple including first and second legs;
- a handle operatively connected to the base, the handle being constructed and arranged to actuate the driver and move the cover towards the base;
- and
- a pair of benders constructed and arranged to engage each of the first and second legs of the leading staple and move the first and second legs into respective cutting paths;
- and
- a cutter having a stationary portion, and first and second, independently movable portions constructed and arranged to independently interact with the stationary portion to cut the first and second legs after first and second, independently movable portions are independently moved into respective cutting paths, with the first and second independently movable portions being movable independently from the benders.
