Description
APPEAL from the Circuit Court for the District of Massachusetts, in which court E. H. Graham filed a bill against one Mason for injunction and account; the bill being founded upon letters-patent for an 'improvement in picker-staff motion for looms,' granted to him, October 16th, 1860, and reissued May 28th, 1867; which patent and reissue the bill alleged that a machine of Mason, the defendant, infringed. The object of the invention patented to the complainant was to produce an accurate and sure picker-staff motion in looms by a combination of devices, which, while giving great accuracy of motion, should so guide and hold the picker-staff as to enable it to work with the least possible friction and lateral disarrangement, commonly called 'wabbling.' In all picker-staff motions it is desirable, if not essential, that the end of the staff made to strike the shuttle should move in a right line, so as to drive the shuttle directly along the shuttle-race in the line in which it is desired to play.
