Abstract
The present invention relates to a novel cutting apparatus capable of effectively cutting a material via movement in at least two different directions. In certain embodiments, the cutting apparatus comprises cutting elements with at least two cutting surfaces. Such cutting elements are capable of effectively penetrating a material when moved with an applied force in the direction that at least one cutting surface is oriented. Such cutting elements may be configured for use with a variety of cutting apparatus, including but not limited to chainsaws.
Claims16
A cutting apparatus, comprising:
- a plurality of cutting elements, a plurality of anti-kickback connecting links, a plurality of elongated elements, a plurality of bar guide links, and a plurality of rivets;
- said cutting apparatus comprised of a continuous repeating series of cutting elements of said plurality of cutting elements, anti-kickback connecting links of said plurality of anti-kickback links and elongated elements of said plurality of elongated elements forming a first chain side connected to an offset and opposing continuous repeating series of cutting elements of said plurality of cutting elements, anti-kickback connecting links of said plurality of anti-kickback links and elongated elements of said plurality of elongated elements forming a second chain side via said plurality of bar guide links and said plurality of rivets;
- said plurality of bar guide links positioned between the first chain side and the second chain side forming a plurality of points of first and second chain side attachment set on an apparatus midline;
- each of said anti-kickback links of the plurality of anti-kickback links on said first chain side and second chain side positioned across from a corresponding anti-kickback link of the opposite chain side, and said cutting elements being alternating and offset from corresponding cutting elements of the opposite chain side;
- each cutting element of the plurality of cutting elements includes a cutting element body comprising an inverse L-shaped protrusion projecting upwardly and outwardly from the cutting element body forming a cutting element tooth oriented inward toward said apparatus midline;
- each inverse L-shaped protrusion including a main body portion projecting upwardly from a corresponding cutting element body and a horizontal protrusion projecting therefrom forming the cutting element tooth;
- each cutting element tooth including two cutting element tooth surfaces on each inverse L-shaped protrusion;
- a first cutting element tooth surface of the two cutting element tooth surfaces forming a first cutting edge oriented in a first direction, and a second cutting element tooth surface of the two cutting element tooth surfaces forming a second cutting edge oriented in a second, opposite, direction thereby allowing the cutting apparatus to penetrate a substance via moving in said first direction or said second direction;
- said each of said plurality of anti-kickback connecting links positioned adjacent to said adjacent cutting element on the same chain side of said cutting apparatus;
- said each of said anti-kickback connecting links having a raised, upwardly planing tooth including an outer curved surface planing gradually upward toward said adjacent cutting element corresponding to first or second chain side;
- the raised, upwardly planing teeth configured to control depth of the cut of a given cutting element penetrating into the material being cut;
- each of said plurality of elongated elements positioned across the apparatus midline from a corresponding cutting element on the opposite chain side;
- a first side chain and a second side chain wherein each of said plurality of bar guide links include a coplanar, downward planing tooth for cutting apparatus propulsion in either of the first direction and the second direction;
- and
- said plurality of rivets joining each bar guide link, cutting element, anti-kickback connecting links and elongated element to one another at the plurality of contact points.
