Saw guide apparatus

Claim 2

Saw guide apparatus comprising a pair of guide arms to be positioned on opposite sides of a saw blade during operation thereof, said arms when in position having inner surfaces opposed to, parallel with and normally slightly spaced from opposite faces of the blade, said arms extending longitudinally substantially across the direction of movement of the saw blade, and means for directing a liquid under pressure through and outwardly from said surfaces substantially throughout the length thereof so as to apply films of said liquid on the faces of the blade and to flush out the spaces between the blade faces and said arm inner surfaces, thereby normally forming a liquid surface between the blade faces and the adjacent arm inner surfaces, cooling and lubricating the blade, and keeping particulate material from lodging in said spaces.

Claim 3

Saw guide apparatus as claimed in claim 1 in which said liquid-directing means are formed by openings in said arm surfaces, and means for directing liquid to and through said openings.

Claim 4

Saw guide apparatus as claimed in claim 1 in which said liquid-directing means are formed by a slot in each of said arm surfaces, and means for directing liquid to the arm slots.

Claim 5

Saw guide apparatus as claimed in claim 1 including a wear pad mounted on each guide arm and forming said surface thereof, said liquid-directing means of each arm being in the wear pad thereof.

Claim 6

Saw guide apparatus including at least one saw blade mounted for cutting operation, and a guide unit for each blade; each guide unit comprising a pair of guide arms positioned on opposite sides of the saw blade, said arms having inner surfaces opposed to, parallel with and normally slightly spaced from opposite faces of the blade, said arms extending longitudinally substantially across the direction of movement of the saw blade, and means for directing a liquid under pressure through said surfaces substantially throughout the length thereof and on to the blade therebetween to apply films of said liquid on to the faces of the blade and to flush out spaces between the blade faces and said arm inner surfaces, thereby normally forming liquid surfaces between the blade faces and the adjacent arm inner surfaces, cooling and lubricating the blade, and keeping particulate material from lodging in said spaces.

Claim 7

Saw guide apparatus including at least one saw blade mounted for cutting operation, and a guide unit for each blade; each guide unit comprising a pair of guide arms positioned on opposite sides of the saw blade, said arms having inner surfaces opposed to, parallel with and normally slightly spaced from opposite faces of the blade, said arms extending longitudinally substantially across the direction of movement of the saw blade, and means for directing a liquid under pressure through said surfaces substantially throughout the length thereof and on to the blade therebetween to apply films of said liquid on to the faces of the blade and to flush out spaces between the blade faces and said arm inner surfaces, thereby normally forming liquid surfaces between the blade faces and the adjacent arm inner surfaces, cooling and lubricating the blade, and keeping particulate material from lodging in said spaces.

Claim 8

Saw guide apparatus as claimed in claim 5 in which said liquid-directing means for each guide unit are formed by openings in said arm surfaces, and means for directing liquid to and through said openings.

Claim 9

Saw guide apparatus as claimed in claim 5 in which said liquid-directing means for each guide unit are formed by a slot in each of said arm surfaces, and means for directing liquid to the arm slots.

Claim 10

Saw guide apparatus as claimed in claim 5 including a wear pad mounted on each guide arm and forming said surface thereof, said liquid-directing means of each arm being in the wear pad thereof.
