ABSTRACT:
A universal slip-on pen cartridge device for attachment to the movable pen arm of chart recorders, has a molded plastic body with ink reservoir and stylus. The flat surface of the pen body has upstanding spaced-apart posts which secure in place by means of sonic welding a bridge member that has a shallow groove in its face which adjoins the pen body. A tunnel is thus formed with the pen body, into which the pen arm can be inserted, said arm having an aperture which accommodates a nib on the pen body to retain the parts in assembled relation.
