ABSTRACT:
A special purpose workbench for holding chain assemblies in the nature of tire chains. A table with a flat top has a vertical transverse wall located near one end and movable to a number of different locations. A similar wall at the opposite end of the table is fixed in one embodiment and movable in other embodiments. The walls are provided with hooks to engage the ends of longitudinal chain sections between which transverse chain sections extend. An apparatus for determining the location of one wall includes a central bar having holes, the wall having a flange with matching holes through which a locking pin can be placed. Guide brackets are provided at the ends of the wall to engage parallel side edges of the table. The means for adjusting the other wall includes either a threaded shaft engaging a threaded member on the wall or a fluid-actuated piston and cylinder assembly with control means. When the second wall is movable, guide means engaging the table edges are provided.
