Appeal No. 2000-1492 Application No. 09/255,276 member. Each end member includes radially projecting lugs 18, 20 that are received in notches 22, 24 in the core member to facilitate the transmission of torque and axial pressure from the end member to the core member (column 3, lines 55-57). In addition, the inner annular surface of the end member includes notches 26, 28, 30, 32, the purpose of which is to engage a key on a chuck (column 2, lines 1-16; column 4, lines 60-64). Accordingly, rotational movement of the chuck can be imparted to the end member and thence to the core member. Bushell relates to a paper tube 3 having plastic end ring supports 7, 9. As can be seen from a review of the drawing figures, especially Figure 2, the paper tube and end rings are constructed such that the tube and end ring assembly has a uniform inside diameter and a uniform outside diameter. As explained at column 1, lines 21-27, heavy gauge tubes of this type may be used to wind yarn or cloth, or for holding heavy items such as carpeting. These heavy gauge tubes “are usually supported on mandrels so that the product can be loaded onto the tube or removed from the tube” (column 1, lines 27-30).
