A short dictionary entry on the wool-oiler, a device fitted to the first breaker card over the feed-apron in woolen manufacture. It explains how a traversing oil reservoir with a rack and pinion, revolving cocks and a rose-nozzle spreads oil on the wool entering the card, and how the flow is regulated. It also describes a variant (Fig. 7350) in which oil drips into a perforated pipe and gauze cylinder that presses it into the wool. One line drawing illustrates the apparatus.
