Definitions

  • the object of thepresent invention is a typewriter so' designed as to have small dimensions, to such a degree that it can be contained in an average size pocket and can be utilized without any support, being simply'held'in the hand.
  • the usual typing roller which is heavy and cumbersome and which causes an unbalance of the machine owing to the excess weight of the rear part is omitted;
  • the types instead of being recorded along parallel lines, as'j usual, are recordedalong a curved line Winding around a center and approaching gradually closer to this center.
  • fthe sheet of paper is associated with a supporting plate which is itself preferably circular and driven in va rotational'movement around its center and, simultaneously in a rectilinear translational motion, each step by'step displacement beingcausedby a stroke or other equivalent action on a key with a'view to the recording of a character or :to the 'obtention of a spacing.
  • the supporting plate may be mounted rotationally around an axis carried by a frame which can itself'lslide freely according to a rectilinear motion -pf-tianslation; V -Other-features ofxtheinvention willfbe apparent from the following description of a 'partic ular type of embodiment with reference ;to the appended drawingswherein'z g j Figure 1 is a view in plan.
  • Figure 2 is a view from underneath.
  • Figure 3 is a view in longitudinal section, along line I IL-III oftheprevious iigurcsl s
  • Figures 4 and 5 aresidj view; showing respectively the machine 'in its operatiiigcondiv tion and opened for changing the pa'per;
  • Figure? shows the paper usedf V Figure 8 shows the same paper foldedigcon ing bar 3 through a flexible rod device .4 such, for instance, as the one which is an object of my copending patent application Serial No. 40,501, filed July 24, 1948.
  • the characters are recorded on the sheet of paper 5 by means of the inked ribbon 6 whose particular features will be indicated later; every time a key is acted upon, a forward displacement of the transverse rod 1 is caused, which rotates the lever 8 actuating the bar 9 carrying a pawl i 6 and rotates the toothed wheel ll by one tooth; this toothed wheel l l is rotationally associated with a shaft l2 whereon is keyed the conical pinion l 3 engaging the conical pinion M keyed on the shaft 15 atthe other end of which is keyed the pin carrying pinion l6; 1 a
  • the pin carrying pinion It may have its pins engaged in the holes ll. arranged in the supporting plate 18 along a curve which winds around the center of said plate, approachingc'onstantly closer to said center; thiscenter is materialized by a part 19 with which the supporting" plate is associated for motions of rotation and translation, comprising a square head 20 which drives rotationally the sheetsof paper 2 l and a circular base'22 rotationally mounted inthe transverse plate 23, extended on both sides by longitudinal arms 24 which guide its longitudinal sliding.
  • the striker plate 29- is'inserted, carried by the transverse rod 29a which also carrie's akniie til whose function will be explained presently.
  • a Y r The sheets of paper; 21' preferably consist. of discs 2lb, 21c, 2ld, joined togetherzby gluing. 3
  • the inked ribbon 6 is an endless ribbon passing underneath the guide 32 of the type carry-,
  • the casing 43 comprises a recess 44 corresponding to each one of the keys and the latter consist of fingers 45 arranged in each of the recesses and not extending above the upper surface of the casin 43; these fingers 45 are extensions of the flexible rods 4 for the'control of the type carrying bars; with this device, instead of striking the key it-is pulled forward-with the finger.
  • a pocket typewriter comprising keys corresponding to the various letters, pivoted type carrying levers, linking strips between the keys and the pivoted levers to set these levers in motion by the action of the keys, a supporting plate endowed both with a rotational motion and a rectilinear translational motion for receiving circular sheets of paper on which the typing is to be effected along a curved line around the center of rotation, and means for causing, by the action of the keys, ,a step by step rotational and translational displacement of the .plate and of the sheets of paper it carries at each character recording or spacing operation.
  • a pocket typewriter comprising keys corresponding to the various letters, pivoted type carrying levers, linking strips between the keys and the pivoted levers to set these levers in motion under the action of thekeys, a centrally pivoted supporting plate for carrying circular sheets of rotatory pinion provided with pins engaging with the holes of the supporting plate, means for rotating said pinion by one tooth at each stroke on a key, and lateral guides for said supporting plate so that the latter may be displaced according to a translational motion at the same time that it pivots around its pivot center.
  • a pocket typewriter comprising keys corresponding to the various letters, pivoted type carrying levers, linking strips between the keys and the pivoted levers to set these levers in motion under the action or the keys, a supporting plate endowed both with a rotational motion and a rectilinear translational motion for supporting circular sheets of paper on which the typing takes place along a curved line around the center of rotation, means for causing, by the action of the keys, a step by step displacement of the plate and of the sheets of paper it carries at each recording or spacing operation, an endless inking ribbon, and means including a rotary knurled pinion for advancing said ribbon under the action of the keys.
  • a pocket typewriter comprising keys corresponding to the various letters, pivoted type carrying levers, linking strips between thekeys and the pivoted levers to set these levers in motion under the action of the keys, a supporting plate endowed both with a rotational motion and a rectilinear translational motion for carrying circular sheets of paper whereon the typing takes place along a curved line about the center of rotation, vmeans for causing, by the action of the keys, a step by step displacement of the plate and of the sheets of paper it carries at each recording or spacing operation, and a striker plate engaged under the upper paper sheet to' separate this sheet from the other sheets.
  • a typewriter comprising a base plate provided with recesses whose number corresponds to that of the keys, keys corresponding to the various letters and consisting of fingers housed inside said recesses, pivoted type carrying levers, linking strips rigidly attached to the keys and connected to the pivoted levers to set these levers in motion under'the action .of said keys, a supporting plate endowed both with a rotational motion and a rectilinear translational motion for supporting circular sheets of paper whereon the typing takes places along a curved line around the center of rotation and means for causing. by the action of the keys, a step by step displacement of the plate and of .the sheets of paper it carries at each recording or spacing operation.
  • a rotatory and transversely movable support for carrying a stack of circular paper sheets whereon typing is to be effected along a curved line winding around the center of rotation and approaching uniformly closer thereto, in combination with a lmife engageable under the top paper sheet for producing automatically the separation of-this sheet in response to the rotation of the support.
