A tool carriage includes a main beam along which a subcarriage carrying the tool travels and is supported above a supporting table by two end parts each associated with opposite ends of the main beam. The main beam has a length sufficient to straddle the widest width of conventional supporting tables and is adjustable at one of the two end parts to accommodate different table widths. The end parts have rollers which support the carriage above the table support surface and against lateral displacement on the table. The lateral rollers on one end of the carriage are capable of being adjusted relative to horizontal and vertically extending directions allowing either end of the carriage to be generically adaptable to any table edge configuration.

A carriage adaptable to be mounted for travel along one of any number of support tables each having a support surface and having varying widths and structures for supporting said carriage for movement in a first coordinate direction, said carriage comprising: an elongate main beam having a first end

A carriage adaptable to be mounted for travel along one of any number of support tables each having a support surface and having varying widths and structures for supporting said carriage for movement in a first coordinate direction, said carriage comprising: an elongate main beam having a first end and an opposite second end the distance between each of the first and second ends defining a beam length being sufficient to straddle a table of maximum width; a first support end part associated with one end of said beam for supporting said main beam above the supporting surface of said table; said first support end part having first bearing means for supporting said main beam above said support surface and having a second bearing means supporting said beam against lateral movement in a second coordinate direction orthogonally disposed in relation to the first coordinate direction; a second support end part associated with said second end of said main beam for supporting said second end of said main beam with said first end part above said support surface of said table; said second support end part having a third bearing means for supporting said beam for movement in said first coordinate direction and having a fourth bearing means for supporting said main beam at said second end against lateral movement while travelling on said table; drive means for moving said carriage along said first coordinate direction; adjustment means for aligning said fourth means relative to said second coordinate direction and to a third coordinate direction extending perpendicularly to said first and said second coordinate direction; and wherein one of said first and said second support end parts is adjustably connected to said main beam at one of said first and second ends thereof to allow the effective length of said main beam to be varied to permit said carriage to fit across tables of varying width.
