LINEAR CHAIN

摘要

The apparatus can manage linearly the chain without a special means for supporting a free end by connecting a tension spring between front and rear chain blocks. It comprises circular pin holes(3c,3c') perforated in an end of the chain block; long pin holes(3d,3d') perforated in the other end of the chain block; connection pins(4,4') for linearly connecting the chain blocks by inserting into the holes; the tension spring(7) connecting the pins; and rollers(5) engaged with grooves of a sprocket and installed on both ends of the connection pins.
