Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
Apparatus for sawing a workpiece, such as logs and the like, comprising: carriage means for moving a workpiece in a forward path of travel to a workpiece sawing station; generally horizontally disposed saw means at said workpiece sawing station for at least partially cutting slabs from said workpieces; means mounting said saw means for vertical movement to adjust to different diameter workpieces and to adjust the thickness of the slabs being cut; slab guide means downstream of said saw means and extending into the path of slabs being cut for vertically guiding cut slabs away from said saw means to prevent said slabs from binding said saw means; and means mounting said guide means for concurrent vertical movement with said saw means to substantially maintain the relative horizontal positions of said slab guide means and said saw means when said saw means is moved vertically.
Claim 2
Dependent Claim
145 words
Apparatus for sawing a workpiece, such as logs and the like, comprising: carriage means for moving a workpiece in a forward path of travel to a workpiece sawing station; generally horizontally disposed saw means at said workpiece sawing station for at least partially cutting slabs from said workpieces; means mounting said saw means for vertical movement to adjust to different diameter workpieces and to adjust the thickness of the slabs being cut; slab guide means downstream of said saw means and extending into the path of slabs being cut for vertically guiding cut slabs away from said saw means to prevent said slabs from binding said saw means; and means mounting said guide means for concurrent vertical movement with said saw means to substantially maintain the relative horizontal positions of said slab guide means and said saw means when said saw means is moved vertically.
Claim 3
Dependent Claim
41 words
The apparatus of claim 1 wherein said slab guide means includes a portion in horizontal alignment with the saw means and disposed in the kerf cut by said saw means for vertically guiding the cut slabs away from the saw blade.
Claim 4
Dependent Claim
72 words
The apparatus set forth in claim 1 wherein said saw mounting means includes a vertical guide rod, a saw means support member slidably mounted on said guide rod for vertical movement, and means on said support member rotatably supporting said saw means; said means mounting said guide means and saw means for concurrent vertical movement comprising a guide means support member fixed to said saw means support member and said guide means.
Claim 5
Dependent Claim
33 words
The apparatus set forth in claim 1 wherein said saw means comprises vertically spaced circular saw members and said slab guide means comprises vertically spaced guide members horizontally aligned with said saw members.
Claim 6
Dependent Claim
22 words
The apparatus set forth in claim 4 including means for independently vertically moving each saw member and the aligned slab guide member.
Claim 7
Dependent Claim
46 words
The apparatus set forth in claim 1 wherein said saw means comprises a generally horizontally disposed saw blade, said slab guide means including means inclined vertically forwardly away from said saw means to guide the cut slabs vertically away from the workpiece and said saw means.
Claim 8
Dependent Claim
44 words
The apparatus set forth in claim 6 wherein said slab guide means comprises a kerf filler having a portion adjacent said saw means of a thickness corresponding to the kerf width of the saw means and a portion downstream of an increased vertical thickness.
Claim 9
Dependent Claim
38 words
The apparatus of claim 1 wherein said saw means comprises circular saw means, said saw mounting means comprises a vertical support shaft and means mounting said circular saw means for axial movement thereon and for rotary movement therewith.
Claim 10
Dependent Claim
64 words
The apparatus set forth in claim 1 wherein said horizontal saw means includes vertically spaced, horizontal saw members for providing vertically spaced kerfs in said workpiece along one side thereof; and vertical saw means is provided downstream of said slab guide means in a plane tangent to said circular saw members for cutting a board from the workpiece portion between the vertically spaced kerfs.
Claim 11
Dependent Claim
30 words
Apparatus as set forth in claim 9 wherein said slab guide means extends into the path of slabs being cut for vertically guiding the cut slabs away from the workpiece.
Claim 12
Dependent Claim
47 words
The apparatus set forth in claim 10 wherein said slab guide means includes a portion in horizontal alignment with said saw means and disposed in the kerf cut by said saw means and a portion downstream thereof for vertically guiding the cut slabs away from the workpiece.
Claim 13
Dependent Claim
53 words
The apparatus set forth in claim 1 including vertical saw means disposed downstream and in a plane generally tangent to said horizontally disposed saw means for cutting a board from said workpiece; said horizontally disposed saw means comprising edger means for removing slabs from at least one vertical edge portion of said board.
