Abstract:
1. A guide device for a backsaw having a bandsaw blade and a blade guide, the backsaw used to cut a carcass longitudinally down a spine of the carcass, the device comprising: a first guide member comprising a wall and a first guide member wing disposed at a separation angle of greater than about 90 degrees from the wall, the first guide member wing having a width of between 1 and 3 inches, wherein at least one of an edge and a rear surface of the first guide member wing is interconnected to a portion of a first surface of the wall of the first guide member, the first guide member wing having a first portion, a second portion, and a third portion, wherein the third portion is continuous with the second portion, the first guide member wing including a transition portion between the first and the second portions, wherein the at least one of an edge and rear surface of the first guide member wing includes at least a part of the first, second, third and transition portions; a second guide member comprising a wall and a second guide member wing disposed at a separation angle of greater than about 90 degrees from the wall, the second guide member wing having a width of between 1 and 3 inches, wherein at least one of an edge and a rear surface of the second guide member wing is interconnected to a portion of a first surface of the wall of second guide member, the second guide member wing having a first portion, a second portion, and a third portion, wherein the third portion is continuous with the second portion, the second guide member wing including a transition portion between the first and the second portions, wherein the at least one of an edge and rear surface of the first guide member wing includes at least a part of the first, second, third and transition portions of the second guide member wing; and a lateral member interconnecting the walls of the first guide member and the second guide member, wherein the lateral member is connected to a second surface of the wall of the first guide member and a second surface of the wall of the second guide member; wherein the wall of the first guide member is substantially parallel to the wall of the second guide member; wherein a connection between the first portion of the first guide member wing and the wall of the guide member defines a first reference line, a connection between the second portion of the first guide member wing and the wall of the guide member defines a second reference line, a connection between the third portion of the first guide member wing and the wall of the guide member defines a third reference line, and a connection between the transition portion of the first guide member wing and the wall of the guide member defines a transition reference line; wherein the first and second reference lines are substantially perpendicular, the transition reference line forms a transition angle of between 20 and 30 degrees with respect to the second reference line, and the third reference line is substantially parallel to the first reference line; wherein the first, second and transition portions engage the carcass during a cut of the carcass.
