Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
A clamp preventing warping of a panel formed from edge-glued boards, during gluing of said boards, said clamp comprising: first and second opposing jaw means for maintaining boards in lateral registration, each jaw means being tubular and having a central longitudinal axis and opposing first and second ends, said respective first and second ends of said first and second jaw means opposing each other, respectively; adjustment means, proximate each of said respective opposed first and second ends of said jaw means, for engaging said jaw means, adjusting the separation of said jaw means and retaining said jaw means in position during use, said adjustment means comprising first threaded nut means for engaging a threaded article, said nut means being disposed within and being attached to said first jaw member offset from said axis proximate said first end of said first jaw member, a threaded rod for engaging said first nut means, said rod having a head, and said second jaw member includes, proximate its first end, an aperture for receiving said rod to engage said head and said second jaw member.
