A short dictionary entry on the dye-vat from Knight's American Mechanical Dictionary. It describes a vat in which cloth is saturated with dye or mordant, and explains a machine where a stitched endless piece of cloth is coiled around rollers so it is alternately dipped and raised, then passed through wringing rollers. A second form is also shown, in which goods in a basket are dipped into the vat with a crank and rope. Two line drawings (Figs. 1810 and 1811) illustrate the equipment.
