Apparatus for a moving workpiece

An apparatus for doing work to a material moving gong a path relative to the apparatus the apparatus, comprising:

• (a) first and second guide arms, each guide arm including a number of links connected substantially end-to-end to define a multiple bar linkage arrangement;
• the number of links including at least a first link, a last link, and at least one intermediate link;
• (b) a tool mount having a first end connected to the first guide arm, and a second end connected to the second guide arm;
• (c) first and second rotation mechanisms, the first rotation mechanism being attached to the first guide arm first link and the second rotation mechanism being directly attached to the first guide arm last link;
• (d) whereby rotation of the first and last links of the first guide arm causes movement of the tool mount in the path of the moving material;
• and
• (e) synchronization means connected between the first and second guide arms;
• whereby rotation of the first and second rotation mechanisms at the first guide arm causes synchronous motion of the second guide arm;
• wherein the synchronization means includes third and fourth rotation mechanisms connected to the second guide arm first and last links, respectively.

An apparatus for doing work to a material moving along a conveyor, the apparatus comprising:

• (a) first and second guide arms, each comprising a first link, a last link, and at least two intermediate links rotatably connected end-to-end to define a multiple bar linkage arrangement;
• (b) a tool mount having a first end portion connected to the first guide arm at one of the end-to-end rotatable connections between two of the at least two intermediate links of the first guide arm;
• the tool mount further having a second end portion connected to the second guide arm at one of the end-to-end rotatable connections between two of the at least two intermediate links of the second guide arm;
• (c) first and second rotation mechanisms, the first and second rotation mechanisms each being attached to at least one of the first and last links of at least one of the first and second guide arms;
• (d) whereby rotation of the first and second rotation mechanisms causes movement of the guide arms and movement of the tool mount in the path of the moving material;
• (e) means for synchronizing movement of the first and second guide arms;
• the synchronization means comprising at least one coupler link pivotably connected between corresponding links of the first and second guide arms;
• and
• (f) whereby rotation of the first and second rotation mechanisms causes synchronous motion between the first and second guide arms.
