Sheet-met′al Scour′er.
A machine for cleaning sheet-brass and other metal after annealing. The metal being drawn through the machine is held against the wire brushes B C by the riders b c, and it is thus scoured and polished. See also Figs. 4962, 4971. [2147] A series of rollers covered with an elastic or fibrous material for holding sand, is so arranged as to pass the sheetmetal alternately above and below a roller. A vibrating motion is given to two of the under rollers by connecting-rods attached to crank-pins peculiarly arranged on pulleys. A pivoted brush is made to reciprocate across the under surface of the sheet-metal.Machine for drying and scouring sheet-metal. |
