Abstract

The new feature of this device is a print wire for a wire printing matrix. The wire carries its own supply of ink and does away with the need for an inked ribbon. As shown, a printing unit is made with a desired number of wires 1 in a protective tube 2 and guided at their printing end in a guide 3. The other ends of the wires, see Fig. 2, are connected to individual armatures 4 within solenoids in a print head 5. Between their ends, the wires 1 pass through an ink reservoir 6, having one or more gaskets 7 to prevent loss of ink by spillage or evaporation.

Self Inking Printing Wires

The new feature of this device is a print wire for a wire printing matrix. The wire carries its own supply of ink and does away with the need for an inked ribbon. As shown, a printing unit is made with a desired number of wires 1 in a protective tube 2 and guided at their printing end in a guide 3. The other ends of the wires, see Fig. 2, are connected to individual armatures 4 within solenoids in a print head 5. Between their ends, the wires 1 pass through an ink reservoir 6, having one or more gaskets 7 to prevent loss of ink by spillage or evaporation.

Each wire 1 is made as a capillary tube, see Fig. 2, with a slot in the side of the tube 1 where it passes through the ink reservoir 6. The printing end of the tube is open and may be formed as desired to deposit ink on a paper when it is contacted by the wire. Due to the capillary action of the tube, as ink is deposited on the paper, the internal supply of ink in tube 1 will be continually replenished from the reservoir 6 so that the wire can always be ready to print when actuated.
