Definitions

  • This invention relates to an inking device for the types of typewriting and similar machines with a reservoir for the ink adapted to oscillate against the action of a spring to get in the path of the type.
  • the ink reservoir is tapered towards the point at which the type strikes, openings for the outflow of ink being arranged. in this tapered part, said openings being covered with ink-absorbing material.
  • the tapering shape of the reservoir forces the-ink towards the outflow openings, the flow of ink bein further assisted by the action of the centrii ugal force occurring at the oscillation of the reservoir. In this manner a suflicient amount of ink is always supplied to the types.
  • FIG. 1 and 2 show respectively in elevation and plan view the improved inking de vice and the corresponding parts of a type writing machine.
  • Fig. 3 is a cross section, through the ink reservoir.
  • Figs. ,4 and 5 show respectively in front elevation and lan view a second form of construction of the device.
  • an arm I On the one side face of a T-shaped flat iron f fixed on the type bar segment of a typewritin machine and carrying the head 9 for gui .ing the type an arm I) is fixed which is approximately S-shap'ed and has an arm 6 of circular cross section which serves as pivot axle for the ink reservoir a.
  • This arm b is parallel to the typing lane.
  • the reservoir ⁇ a is tapered at the en where the type strikes so that it has approximately triangular shape similar to a soldering copper, the small edge being rounded.
  • a sleeve j which traverses the reservoir 0 is mounted on the arm 12 so that the oint of the reservoir projects in the pat of the types 1".
  • a spring d serves to hold the reservoir normally in such position that it crosses the path of the types.
  • an inlet opening closed by a screw with interposition of a packing is arranged, and outflow openings 2' (Fig. 3) for the ink are arranged in the wall of the reservoir turned towards the types.
  • These outflow holes z' are covered by several layers m of silk.
  • the ink reservoir a shown in Figs. 4 and 5 comprises a cylindrical part and a wedge shaped part forming a kind of snout.
  • the holes i are arranged on the flat side of the snout, said snout being closed by av lid 7:
  • the holes '11 are covered by layers m of silk adapted to absorb the ink.
  • the reservoir a is mounted on the end 6 of arm I) said end of arm I) serving as pivot pin.
  • a thin wire spring (5 is wound, the one end of said wire spring is attached to the end 12 of arm I) and the other end to a pin it on the lid of the reservoir.
  • two pins 0, 0 are fixed at a certain distance apart the one opposite the other, and designed to limit the oscillating movements of the ink reservoir by'bearing against the arm I) and checking the action of the s ring d
  • a type 1" When a type 1" is operate by the depression of a key, a push lever or oscillating lever or the like, it strikes against the end of the ink reservoir in which the silk covered outflow openings 2' are arranged, so that the face of the type is inked and the reservoir oscillates around its pivot axle 6 against the action of the spring (position shown in Fig. 2 in dash lines).
  • An inking device for the types of typewriting and similar machines comprising in combination an ink reservoir having a tapered front end, means to position its front end in the path of any type key upon depression of such type key, the tapered front end of'the ink reservoir having outflow openings, and an ink padover the outflow open- 1ngs.
  • writing and similar machines comprising in elastic means to bias the reservoir to posicombination an ink reservoir having a tation the front end in the type keys path.
  • pered front end means to osition its front In testimony whereof we affix our signa- 1 end in the path of any t pe ey u on deprestures sion of such type key, t e tapere front end ARTHUR ROTTER.
