Stir′rer.
A mechanical device to keep a solution from settling. The mechanical stirrer for color-pans in a calico-printing works consists of a brass rod bent into the form shown at a. Two of these are suspended in each pan by hooks from the shafts b b, collars c c slipping over the joints. The shafts b b have independent rotation by the spur-wheels meshing with a wheel on the shaft d, from which they both depend, and which is itself rotated by bevel gears above. The stirrers are thus revolved around the pan, and rotate around each other, so as to be brought in contact with every part of the color. When the process is finished, the collars c c may be slid up and the stirrers unhooked. The pans are supplied by pipes with steam and cold water. |
