A one-page patent abstract from the journal Engineering describing British patent 10,097 (A. Lees and Co. and J. Clegg, Oldham) for an improved winding arm and toothed quadrant for self-acting mules and twiners. It explains how the quadrant is cast with a central boss and lugs, bored, turned and machine-cut, then bolted to the winding arm so the arm can be replaced without disturbing the shaft. Three engineering drawings accompany the text.
