  • a spring 204 normally holds the feeler 208 against the outer diameter of the rewound film.
  • the printing platen is so constructed that, as the platen strikes the ribbon and the type wheel, the platen is given a slight sidewise movement to in effect rub the magnetic ink material onto the record material, by sliding it slightly across the face of the type character. Also, the platen is constructed to dwell on the type at the time of impact. This is necessary,'inasmuch as an ordinary blow does not make uniform impressions of the magnetic material on the record material.

  • the hammer 236 is provided with an insert 237, which is set in resilient material 238, such as rubber.
  • the purpose of the rubber insert 238 is to provide an increase in contact time against the ribbon; that is, to increase the time during which pressure is exerted against the ribbon to obtain a better imprint from the magnetic ink. Tests have shown that a quick blow by the hammer does not transfer sufiicient magnetic ink to obtain usable impressions.
  • the lower end of the platen 210 is slightly beveled, as at 240, and therefore, as the platen is engaged with the type as above described, the lower end of the platen is cammed sidewise a slight extent, due to the action of the bevel 240 on the type carriers and the sliding fit of the platen 210 in the frame'211.
  • This sidewise shifting causes a rubbing action on the printing film, to rub the magnetic material onto the record material, which, taken with the dwell at the time of impact, 'causes a good print to be made on the record material.

A similar pinion, which meshes with the teeth of a segment 250, is mounted on the opposite end'of'the shaft 232. The segments 24? and 250 are pinned to the shaft 251.

  • the cam arm 254 is pivoted on the shaft 151. Action of the spring 252 against the upper end of the arm 254 maintains the roller 255 in engagement with the cam 256.
  • Rotation of the cam 256 when the cam shaft 56 is operated permits the cam arm 254 to rock clockwise, thus permitting the segments 249 and 250 to rock clockwise, to rock the pinions 247 counter-clockwise to move the rod 245 counter-clockwise, thus permitting the hammers to operate in the manner above described.
  • the cam 256 reverses movement of the cam arm 254.
  • the printing mechanism also includes a platen 260 (Fig. 3), for printing a special symbol. During certain operations, it is desired to suppress the printing of this symbol.
