FEED MECHANISM FOR MARKING MACHINE Abstract A marking machine for marking metal nameplates, tags or the like. The marking machine employs a work table supported on a carriage which is moveable into contact with a marking wheel to perform a printing operation. Improved advancing means are provided for the work table utilizing a feed pawl link having a pair of pivot points. One pivot point is connected to a feed link while the second pivot point is connected to a drag link moveable between upper and lower stops in a carriage casting. A bottom pivot point of the drag link is provided with a friction clutch on a pivot connected otherwise to a stationery portion of the machine. An improved feed rack is further provided which is polygonal in cross-section and may have different spaced teeth on each side for selective spacing. Half-spacing adjustment means are provided whereby the feed rack may be moved axially a half-space to change the spacing on the work table. An improved carriage release is further provided which comprises a control member pivoted on the same pivot as the pivotable feed link and engageable with the feed link to cause the feed pawl to move both of its teeth out of engagement with the feed rack to provide for manual movement of the work table as desired.
