Abstract
A replaceable saw tooth for a rotary cutting machine. The saw tooth comprises more than two cutting edges on each of two opposed faces thereof. More specifically, the saw tooth may comprise a body having two cutting faces disposed opposite each other and spaced apart by at least four side faces which are each parallel to an opposite one of the side faces. The side faces are parallel to a central axis extending between the two cutting faces. Four cutting edges are defined between the side faces and each of the two cutting faces.

A replaceable saw tooth for a rotary cutting machine, the saw tooth being reversible and having more than two cutting edges at least partially defined by each of a first face and a second face thereof, said second face being opposite said first face.
A cutting tooth for a rotary cutting machine, said cutting tooth comprising a body having two cutting faces disposed opposite each other and spaced apart by at least four side faces which are each parallel to an opposite one of said side faces, said side faces being parallel to a central axis extending between said two cutting faces, each said cutting faces comprising four cutting edges defined at the intersection between two adjacent side faces and each said respective cutting face.
A replaceable saw tooth comprising:
- opposed front and rear faces, each of which at least partially defining at least two cutting edges;
- a central aperture extending through the saw tooth between said front and rear faces, said central aperture defining a central axis therethrough, said central axis being perpendicular to a reference plane;
- and
- at least four side faces, each parallel to said central axis and extending between said front and rear faces, each of said side faces defining a face plane which is perpendicular to said reference plane, said side faces each having a perimeter thereabout defining a planar shape in said face plane, said planar shape being substantially similar for each of said side faces.
A saw tooth assembly for a rotary cutting machine comprising:
- a saw tooth holder adapted for mounting about the periphery of a circular saw disk of the rotary cutting machine;
- and
- a reversible saw tooth, removably mounted to said saw tooth holder, said saw tooth having opposed first and second cutting faces each of which at least partially defining more than two cutting edges.
A rotary cutting machine comprising:
- a saw disk;
- a plurality of saw tooth holders disposed on the saw disk at spaced apart locations about its periphery;
- and at least one reversible saw tooth removably fastened on said saw tooth holder such that at least one cutting edge is disposed in a operable cutting position, each said saw tooth having opposed first and second cutting faces spaced apart by lateral surfaces extending therebetween, each of said first and second cutting faces defining at least four of said cutting edges thereon, and wherein said saw tooth is selectively mountable on said saw tooth holder in any one of at least eight different positions, each of said positions providing a different one of said cutting edges in said operable cutting position.
A method of installing a saw tooth on a saw tooth holder of a rotary cutting machine, the method comprising:
- providing a reversible saw tooth having at least two opposed cutting faces, each of said cutting faces at least partially defining at least four cutting edges thereon, such that said saw tooth includes at least eight individual cutting edges;
- selecting one of said eight cutting edges for use;
- positioning said saw tooth in a location on said saw tooth holder such that said selected cutting edge is disposed in an operable cutting position;
- and
- removably fastening said saw tooth in said location on said saw tooth holder.
A kit comprising a saw tooth removably fastenable to a saw tooth holder of a rotary cutting machine and an adapter for mounting intermediately between said saw tooth and said saw tooth holder, said saw tooth having opposed first and second cutting faces each of which at least partially define more than two cutting edges.
A saw tooth assembly for a rotary saw comprising:
- a saw tooth holder for mounting on the periphery of a circular saw disk of the rotary saw, the saw tooth holder having a longitudinal axis extending substantially tangential to the periphery of the circular saw disk when the saw tooth holder is mounted thereon;
- a reversible saw tooth, removably mounted to said saw tooth holder, the saw tooth having opposed first and second cutting faces each of which partially define more than two cutting edges, the saw tooth having a central axis extending perpendicular to the cutting faces;
- and
- the saw tooth holder including a seat for receiving the reversible saw tooth, wherein the central axis of the saw tooth is disposed at an angle relative to the longitudinal axis of the holder.
A rotary cutting machine comprising:
- a saw disk;
- a plurality of saw teeth removably mounted to said saw disk at spaced apart locations about its periphery, the saw teeth being reversible and removably fastened to said saw disk such that at least one cutting edge is disposed in a operable cutting position;
- and wherein each of said saw teeth includes opposed first and second cutting faces spaced apart by lateral surfaces extending therebetween, each of said first and second cutting faces defining at least four of said cutting edges thereon, such that said saw teeth are selectively mountable on said saw disk in any one of at least eight different positions, each of said positions providing a different one of said cutting edges in said operable cutting position.
A reversible saw tooth for a rotary cutting machine comprising:
- a body having opposed front and back faces and opposed distal and proximal faces spacing apart opposed superior and inferior faces, said front and back faces being spaced apart by said distal and proximal faces and by said superior and inferior faces;
- each said front and back faces comprising four projections projecting therefrom, one of each of said projections being located at the intersection of said distal and said inferior faces, said distal and said superior faces, said proximal and said inferior faces and said proximal and said superior faces, and each said projection comprising a base tapering to an upper edge, said upper edge comprising a cutting surface;
- and
- said tooth further comprising a front bore disposed in said front face and a back bore disposed in said back surface.
A reversible saw tooth comprising:
- a body having opposed first and second faces being spaced apart by at least opposed third and fourth faces and opposed fifth and sixth faces;
- each of said first and said second faces comprising a cavity, said cavity being defined by four lateral surfaces and a bottom surface;
- each of said lateral surfaces being bound by downwardly diverging first and second lateral edges and by a bottom edge, said first lateral edge intersecting with the first lateral edge of an adjacent lateral surface and said second lateral edge intersecting with the second lateral edge of an adjacent lateral surface, said bottom surface comprising an orifice therethrough;
- wherein said first lateral edge and said second lateral edge of each said lateral surface converge upwardly so as to form a cutting edge.
A reversible saw tooth having:
- opposed first and second surfaces spacing apart third and fourth surfaces, each said first, second, third and fourth surfaces spacing apart opposed front and back surfaces;
- each said opposed first and second surfaces comprising opposed front and back edges disposed adjacent said respective front and back surfaces, each said front and back edges comprising a recessed portion having an opening adjacent said respective front and back surfaces;
- each said opposed third and fourth surfaces comprising opposed front and back edges disposed adjacent said respective front and back surfaces, each said front and back edges comprising a recessed portion having an opening adjacent said respective front and back surfaces;
- and
- said from and back surfaces being recessed towards each other, each said front and back surface comprising a bore therethrough.
