Definitions

  • FIG. 4 a detail in accordance withV the invention.
  • the typewriter is. indicated in dash-and-dot lines.
  • the typewriter is in the conventional manner fitted with a carriage carrying a roller 2.
  • the copy holder 3 is secured to a holder 4 pivoted on journals 5. These journals are supported in such a manner that their movements can be adjusted by means. of the wing nuts E, this being preferably obtained in a manner as to permit the holder 4 to be swiveled by hand, but to remain in the. adjusted position without changing the latter.
  • the copy holder is permitted to be swung forward down to the keyboard of the machine, should any alterations or additionsbe required in the copy.
  • the holder is curved, as shown, in Figure l, so that the lateral, bows of the holder extend beyond the movement'of the carriage.
  • the holder 4 and its journals* 5 are carried more highly than shown in Figures 1 and 2, namely about level with' the carriageof the typewriter or higher.
  • the holder is carried by a stand 1.
  • the, holder 4 need not be curved. as shown in Figure l, but may be of any desired shape, e. g., a simple rod, since it is at all times above the carriage of the typewriter and thus"A does not interfere with the movements of the carriage.
  • the copy holder 3 can be fixed to the holder 4 in an adjustable manner,
  • This device consists .of a feed roller 20 secured to the copy holder. .For this purpose it is advisable to use an ordinary .typewriter roller which has been removed from a typewriter together with the slide rail used for movingthe carriage sideways or has been procured separately as a spare part. To this end it will do to provide a threaded hole in the slide rail 2
  • elastic means preferably consisting of rubber are provided between the base -26 and a bottom plate 21 to permit in particular of an upward and lateral movement of the base 26 and thusof'thetype- Writer corresponding to the movements 'of the carriage.
  • the softer ⁇ touch preserves also-the machine.
  • These elastic means may, e?. g., consist of rubber balls 28 embedded in rounded depressions 29 provided inthe opposite sides of the base and the bottomplat'e.
  • the rounded depressions may be greater than those of the balls, so that the balls are able to roll to a certain extent when the plates are displaced towards each other, while at the same time the distance of their rolling surfaces decreases in accordance with the curvature of the rounded depressions, so that the lateral movement is damped.
  • the elasticity of the flexible means between the two plates is preferably smaller on that side towards which the carriage is moving. Further the elasticity of the flexible means can 'be smaller under the keyboard of the machine than at the back in order to intercept the shocks originating from the pressure exerted on the keys.
  • the two plates 26 and 21 are preferably held together at the edges by bolts 30 by means of which the tension of the elastic means may be controlled.
  • a device for use with a typewriter comprising a copy holder adapted to swing in a plane parallel to the direction of the movement of the carriage of the typewriter.
  • a device for use with a typewriter with a carriage and mounted on a base plate comprising a copy holder connected on the plate to swing in a plane parallel to the direction of movement of the carriage and a stop adapted to limit the movements of said holder.
  • a typewriter having a carriage, a base plate, a bottom plate substantially parallel thereto, rounded depressionsbeing formed in two adjacent sides of said plates, and elastic means between said plates, said means engaging said depressions with provision for a substantially horizontal movement of said base plate in the direction of the movement of the carriage,
  • a device in which a base plate is provided to carry the beam.
  • a copy holder for a typewriter having a carriage comprising a balance beam capable of swivelling about a substantially horizontal axis situated transversely to the movement of the carriage and substantially below the center of gravity of the holder.
  • a typewriter having a carriage, a base plate and a bottom plate, said plates having rounded depressions arranged in the two adjacent sides of said plates, elastic means arranged between said plates and in said depressions, a pivot on said base plate, a shiftable holder adapted to swing on the pivot in a plane parallel to the movements of the carriage, and a copy holder carried by said shiftable holder.
  • HERMANN STEIN For use with a typewriter having a carriage, a base plate and a bottom plate, said plates having rounded depressions arranged in the two adjacent sides of said plates, elastic means arranged between said plates and in said depressions, a pivot on said base plate, a shiftable holder adapted to swing on the pivot in a plane parallel to the movements of the carriage, and a copy holder carried by said shiftable holder.
