Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
Lumber treating mechanism comprising (a) support means, (b) a treating tank on said support means for holding treating liquid, (c) said tank having forward and rearward ends and an open top, (d) conveyor means on said support means movable longitudinally over said tank, (e) said conveyor means including at least one pair of endless upper and lower lines operative over drive and guide pulleys and arranged to receive and frictionally hold lumber pieces therebetween, (f) said upper and lower lines comprising resilient type ropes stretched in a position so as normally to be spaced above a liquid level in said tank, (g) and vertically adjustable hold-down means on said support means engageable with said upper line arranged to force said upper line toward said lower line and frictionally hold lumber pieces therebetween and also to force the assembly of upper and lower lines and lumber pieces down below the level of treating liquid by stretching said lines for treating the lumber pieces as they are conveyed through said tank.
Claim 2
Dependent Claim
169 words
Lumber treating mechanism comprising (a) support means, (b) a treating tank on said support means for holding treating liquid, (c) said tank having forward and rearward ends and an open top, (d) conveyor means on said support means movable longitudinally over said tank, (e) said conveyor means including at least one pair of endless upper and lower lines operative over drive and guide pulleys and arranged to receive and frictionally hold lumber pieces therebetween, (f) said upper and lower lines comprising resilient type ropes stretched in a position so as normally to be spaced above a liquid level in said tank, (g) and vertically adjustable hold-down means on said support means engageable with said upper line arranged to force said upper line toward said lower line and frictionally hold lumber pieces therebetween and also to force the assembly of upper and lower lines and lumber pieces down below the level of treating liquid by stretching said lines for treating the lumber pieces as they are conveyed through said tank.
Claim 3
Dependent Claim
90 words
The lumber treating mechanism of claim 1 wherein said hold-down means comprises a longitudinally extending frame pivotally supported at an upper point on said support means toward one or the other of said forward and rearward ends of said tank, guide pulleys for said upper line spaced at longitudinal points on said frame whereby selected vertical positioning of said hold-down means on its pivot provides varying longitudinal inclined relationships of said longitudinally spaced rollers whereby to vary the submerged length of travel of the lumber pieces through the treating liquid.
Claim 4
Dependent Claim
44 words
The lumber treating mechansim of claim 1 wherein said conveyor means comprises at least three pairs of upper and lower laterally spaced lines with two of said pairs of lines being spaced at different lateral distances apart to accommodate lumber pieces of different lengths.
Claim 5
Dependent Claim
77 words
The lumber treating mechanism of claim 1 including second treating means in said mechanism following said treating tank arranged to remove excess treating liquid, said second treating means comprising an overhead laterally extending nozzle ejecting forced air on the lumber pieces, said nozzle being angled at an acute angle relative to said conveyor means whereby to sweep excess treating liquid to one side, said conveyor means extending through said second treating means to carry the lumber therethrough.
Claim 6
Dependent Claim
26 words
The lumber treating mechanism of claim 4 including third treatment means in said mechanism following said second treatment means arranged to heat dry the lumber pieces.
