Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A shavings making machine comprising a rotating cutter device having a plurality of longitudinally extending cutter blades on its periphery, means providing a moving feed bed for advancing pieces of wood or the like to be converted into shavings under controlled feed conditions into the circular path of said blades, said moving feed Bed comprising a plurality of successive rollers each having a longitudinally serrated surface, said rollers being disposed to rotate on axes substantially parallel to the axis of rotation of said rotating cutter device and one of said rollers being positioned next to said cutter device closely adjacent the bottom of the circular path of said cutter blades, and means for adjustably shifting said rollers together toward or away from said cutter device.
Claim 2
Dependent Claim
125 words
A shavings making machine comprising a rotating cutter device having a plurality of longitudinally extending cutter blades on its periphery, means providing a moving feed bed for advancing pieces of wood or the like to be converted into shavings under controlled feed conditions into the circular path of said blades, said moving feed Bed comprising a plurality of successive rollers each having a longitudinally serrated surface, said rollers being disposed to rotate on axes substantially parallel to the axis of rotation of said rotating cutter device and one of said rollers being positioned next to said cutter device closely adjacent the bottom of the circular path of said cutter blades, and means for adjustably shifting said rollers together toward or away from said cutter device.
Claim 3
Dependent Claim
42 words
A shavings making machine as defined in claim 1, wherein said rollers are of the same diameter and rotated at the same peripheral speed, with their upper surfaces lying in a plane parallel to the axis of rotation of said cutter device.
Claim 4
Dependent Claim
86 words
A shavings making machine as defined in claim 1, wherein said cutter device is a drum having a cylindrical surface from which project said cutter blades, said drum is rotated at a constant speed, and said moving feed bed is adapted to advance said wood toward the drum surface at such a rate relative to the movement of the drum surface that said blades cut successive shavings from the wood and abutment of the leading end of the advancing wood with the drum surface is avoided.
Claim 5
Dependent Claim
52 words
A shavings making machine as defined in claim 1, comprising a substantially flat feed table located forwardly of said roller feed bed, the top surface of the table being substantially in a plane containing the upper surfaces of said rollers and extending parallel to the axis of rotation of the cutter device.
Claim 6
Dependent Claim
29 words
A shavings making machine as defined in claim 4, comprising means above said table for holding work pieces down during advance along said table toward the moving feed bed.
Claim 7
Dependent Claim
25 words
A shavings making device as defined in claim 1, wherein the cutter device is a cylindrical drum with the cutter blades comprising longitudinal projections therefrom.
