Abstract
Abstract In a veneer slicer including a knife having a cutting edge, a knife carrier, a pressure bar, and a carriage or pressure cap for the pressure bar, the carriage being movable relative to the knife carrier and arranged to hold the pressure bar in a predetermined spaced relationship relative to the cutting edge, the improvement comprising first fluid motor means for moving the carriage to move the pressure bar toward and away from the knife, clamping means, and second fluid motor means for operating the clamping means to clamp the carriage in a selected position to hold the pressure bar in a selected position relative to the cutting edge.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
In a veneer slicer including a knife having a cutting edge, a knife carrier, a pressure bar, and a carriage for said pressure bar, said carriage being movable relative to said knife carrier and arranged to hold said pressure bar in a predetermined spaced relationship relative to said cutting edge, the improvement cOmprising first fluid motor means for moving said carriage to move said pressure bar toward and away from said knife, clamping means, and second fluid motor means for operating said clamping means to clamp said carriage in a selected position to hold said pressure bar in a selected position relative to said cutting edge.
Claim 2
Dependent Claim
106 words
In a veneer slicer including a knife having a cutting edge, a knife carrier, a pressure bar, and a carriage for said pressure bar, said carriage being movable relative to said knife carrier and arranged to hold said pressure bar in a predetermined spaced relationship relative to said cutting edge, the improvement cOmprising first fluid motor means for moving said carriage to move said pressure bar toward and away from said knife, clamping means, and second fluid motor means for operating said clamping means to clamp said carriage in a selected position to hold said pressure bar in a selected position relative to said cutting edge.
Claim 3
Dependent Claim
58 words
The invention of claim 1 in which said first fluid motor means includes, adjacent each end of said carriage, a first hydraulic cylinder and its cooperating piston and piston rod, the piston rod of each first cylinder being connected to said carriage for movement therewith, and including means for anchoring each first cylinder relative to said knife carrier.
Claim 4
Dependent Claim
43 words
The invention of claim 2 in which each of said anchoring means includes a micrometer adjustment mechanism including a support member selectively adjustably movable toward and away from said knife, each first cylinder being connected to its associated support member for movement therewith.
Claim 5
Dependent Claim
72 words
The invention of claim 1 in which said second fluid motor means includes, adjacent each end of said carriage, a second hydraulic cylinder and its cooperating piston and piston rod, and in which said clamping means includes, adjacent each end of said carriage, a clamping member proportioned and designed to engage said carriage, each clamping member being operatively connected to the adjacent second hydraulic cylinder and its cooperating piston and piston rod.
Claim 6
Dependent Claim
70 words
The invention of claim 4 in which each clamping member provides an engaging surface cylindrically formed about an axis extending generally parallel to said cutting edge, and in which said carriage is formed to provide, adjacent each of its ends, a generally flat surface generally parallel to the direction of movement of said carriage, each flat surface being disposed to be engaged by one of said cylindrically formed engaging surfaces.
Claim 7
Dependent Claim
82 words
The invention of claim 5 in which said carriage is formed to provide a slot in each flat surface extending through said carriage and elongated in the direction of movement of said carriage, in which the piston rod of each second cylinder extends through the adjacent slot to have its distal end rigidly attached to said knife carrier, and in which each clamping member is carried by the adjacent second cylinder for movement therewith toward and away from the adjacent flat surface.
Claim 8
Dependent Claim
58 words
The invention of claim 6 in which said first fluid motor means includes, adjacent each end of said carriage, a first hydraulic cylinder and its cooperating piston and piston rod, the piston rod of each first cylinder being connected to said carriage for movement therewith, and including means for anchoring each first cylinder relative to said knife carrier.
Claim 9
Dependent Claim
43 words
The invention of claim 7 in which each of said anchoring means includes a micrometer adjustment mechanism including a support member selectively adjustably movable toward and away from said knife, each first cylinder being connected to its associated support member for movement therewith.
Claim 10
Dependent Claim
72 words
The invention of claim 3 in which said second fluid motor means includes, adjacent each end of said carriage, a second hydraulic cylinder and its cooperating piston and piston rod, and in which said clamping means includes, adjacent each end of said carriage, a clamping member proportioned and designed to engage said carriage, each clamping member being operatively connected to the adjacent second hydraulic cylinder and its cooperating piston and piston rod.
Claim 11
Dependent Claim
70 words
The invention of claim 9 in which each clamping member provides an engaging surface cylindrically formed about an axis extending generally parallel to said cutting edge, and in which said carriage is formed to provide, adjacent each of its ends, a generally flat surface generally parallel to the direction of movement of said carriage, each flat surface being disposed to be engaged by one of said cylindrically formed engaging surfaces.
Claim 12
Dependent Claim
50 words
The invention of claim 9 in which each said first hydraulic cylinder is conneCted directly to the adjacent second hydraulic cylinder, said cylinders being proportioned and designed such that, when the piston rods in said first cylinders are fully extended, said second cylinders are operated automatically to clamp said carriage.
