Portable apparatus for shearing multi-walled workpieces

A portable apparatus for shearing workpieces comprising:

• a first means defining an interior for storing;
• a second means pivotally coupled to the first means;
• and
• an third means mounted between the first means and the second means to move the second means between a storage position within the interior and a cutting position.

A portable apparatus for shearing workpieces having at least two sides formed of sheet-like material, comprising:

• (a) housing defining an interior;
• (b) cutting assembly attached to the housing including:
• a first support defining an elongated edge and being engageable with a first side of the workpiece for contacting and supporting the first side of the workpiece along a line defined by the first elongated edge wherein a first section of the first elongated edge adjacent to the workpiece is angled with respect to the line;
• a second support defining an elongated edge and being engageable with a second side of the workpiece for contacting and supporting the second side of the workpiece, the second support being spaced apart from and facing the first support and defining a channel therebetween for receiving the workpiece, wherein a first section of the first elongated edge adjacent to the workpiece is angled with respect to the line;
• a blade slideably received within a gap formed adjacent to the elongated edges of the first and second supports and being movable between a first position spaced away from the workpiece within the channel and a second position in engagement with the workpiece for shearing the workpiece along a line of contact;
• and
• a base support defining a support surface extending between the elongated edges and being engageable with a third side of the workpiece;
• (c) an actuator operatively connected between the cutting assembly and the housing for fixedly moving the cutting assembly between a transport position and a shearing position;
• and
• (d) a plurality of wheels depending from the housing for transporting the apparatus.

A blade for shearing workpieces comprising:

• a cutting surface having
• a primary point defined by the intersection of two portions;
• two secondary points on each side of the primary point, each secondary point defined by one of the two portions and respective secondary portions;
• and
• a cavity adjacent each of the secondary portions for facilitating ejection of trimmed portions of the workpieces.

An apparatus for shearing workpieces comprising:

• a) a housing defining an interior and a work surface when in a shearing position;
• b) a cutting assembly stored within the interior when in a transport position for shearing workpieces, the cutting assembly pivotally connected to the housing such that in the shearing position, the cutting assembly is substantially adjacent and perpendicular the work surface;
• c) an actuator drivingly connected between the housing and the cutting assembly for pivotally moving the cutting assembly;
• d) a motor assembly secured to the housing for driving the cutting head assembly and the actuator;
• and
• e) a fuel supply connected to the motor assembly for powering the motor assembly.
