In this case, the tripod is constructed a few feet from the shaft so that the swing arm is positioned directly over the shaft. A wooden ore bucket is suspende d from a pulley or “Sheave Wheel” attached to the swing arm. With the bucket rai sed, the diagonal arm can be swung to either side of the shaft for dumping. Harris mine, South Lorraine, Ont. c. 1910 Once a depth of 30-ft or more was reached, a whim was often built to replace the windlass. Although usually powered by a horse walking around and around a large drum or gear, this particular whim appears to have been operated solely by “man -power”. A rope extends from the whim, up and over the sheave wheel at the top of this unique “gallows frame”, to connect with the ore bucket.
