270 F. 877 | D.C. Cir. | 1921
White contends that he is entitled to priority over Cottrell in an interference relating to improvements in mechanism for feeding material in sheet form to a printing press. The issue originally involved 36 claims, 3 of which were awarded by the Commissioner to White, and the remainder to Cottrell. White appeals as to the claims denied him. Claims 1, 2, 9 and 36 are illustrative of the others.
1. “A sheet feeding mechanism for printing presses comprising endless means traveling in a partly circular and partly noneircular path for feeding the sheets to the press and devices carried by the sheet feeding means for bringing the sheets into both end and side register with respect to the printing form while they are in motion.
2. A sheet feeding mechanism for printing presses comprising endless means traveling in a. partly circular and partly noncircular path for feeding the sheets to the press and devices carried by the sheet feeding means for bringing the sheets into both end and side register with respect to the printing form while they are in motion, and maintaining control of the sheets until they are brought under the control of the press.
9. A sheet feeding mechanism for printing presses comprising an endless carrier traveling in a partly circular and partly noncircular path having ¡both a sheet stop for end registering the sheet and side grippers for engaging the side edges of the sheet.
36. In a sheet handling and register mechanism, a preliminary feeding means traveling faster than the impression cylinder, moving front stops against which the sheet is registered by the preliminary feeding means, a second feeding means taking the sheet from the preliminary feeding means and traveling at the speed of the impression cylinder and means for moving the second feeding moans sidewise to side register the sheet.
Therefore the decision of the Commissioner of Patents is reversed as to claims 1 to 8, inclusive, 27 to 32, inclusive, and 36, and is affirmed as to the other claims of the issue.
