Definitions

  • ABSTRACT [30] Foreign Application Priority t A teleprinter or the like wherein a typewheel is re- Oct. 14, 1971 Great Britain 47836/71 tated around a helically grooved rod.
  • the typewheel has an internal projection to ride in the groove.
  • the [52] U.S. Cl. 197/49, 74/27 rod is rotated at different speeds for carriage advance, [51] InLCl B4lj 1/32 stop and return, The typewheel is rotated continul ously.
  • FIG. 1 is a top plan veiw of a traversing drive constructed in accordance with the present invention.
  • FIGS. 2 and 3 are enlarged views, partly in section, of the traversing drive shown in FIG. 1.
  • a typewheel drive pinion Pinion 5' is fixed relative to typewheel 1 and meshes with pinion 4'.
  • the typewheel drive pinion 5 is supported on a rotatable cylindrical rod 6' having a helical groove 7 cut into its surface.
  • a tooth in the bore of the typewheel drive pinion 5 (not visible in the figure) engages in the groove, so that when there is relative rotary motion between typewheel drive pinion 5 and rod 6, the typewheel drive pinion 5 travels along the rod like a nut on a bolt.
  • the rod 6, mounted in bearings in the frame of the printer, is fixed relative to one part of a clutch 8' at one end and with one part of a clutch 9 and a brake 10 at the other end.
  • the other part of clutch 8 is fixed relative to a drive which rotates at a speed faster than, and in the same direction as, the typewheel drive pinion 5, and the other part of clutch 9 is fixed relative to a drive which rotates at the same speed and in the same direction of the typewheel drive pinion 5'.
  • the driving arrangement operates in the manner described below.
  • both clutches are disengaged and the brake 10' is applied.
  • the typewheel drive pinion 5 now revolves rapidly with respect to the rod 6, and travels rapidly along the rod 6' to the beginning of a line of print. This motion may be visualized by the bolt with a nut on it being held-stationary while the nut is revolved rapidly in the direction to screw it on to the bolt.
  • the helical groove is provided with a run-out at the line-start end so that the drive pinion can revolve harmlessly without further sideways motion. Normally the clutching and braking operations arrest the traverse motion before the wheel reaches the run-out portion. A similar run-out is provided at the other end as a further safeguard although the typewheel 1' never approaches that end at a high traverse rate.
  • On-the-fly printing requires a hammer carriage which feeds in synchronism .with the typewheel.
  • a simple method of doing this is shown here where the hammer carriage llis linked to the typewheel assembly by virtually inextensible cards 12 passing around pulleys 13' in the manner shown.
  • gear 2 may be press fit or integral with a shaft 15 that is rotatably mounted through a frame stringer 16'.
  • Shaft 15' is rotated by a motor 14'.
  • a pinion 18 in mesh with gear 2 may have a shaft 19 integral therewith or press fit thereinto and press fit into the left end of pinion 3'.
  • Shaft 19 is rotatable through stringer 16' as shown in FIG. 1.
  • the carriage is illustrated at 25.
  • a fitting 22 is shown in FIG. 1 which has a head 23 and a shaft 24 which may -be integral therewith or press fit thereinto or therethrough.
  • Shaft 24' is press fit into the right end of pinion 3, but is rotatable through a frame stringer l7.-
  • Carriage 25' has a projection 21 into which a shaft 20 is press fit, as shown in FIGS. 1 and 3.
  • FIG. 2 the manner in which shaft 'is rotatable through stringer 16' is illustrated.
  • Shaft 15 has grooves 26 and 27 into which snap rings 28 and 29, respectively, are fitted.
  • pinion 4 is maintained in a fixed axial position on and rotatably around stub shaft
  • stub shaft 20 has a snap ring groove 30, and a snap ring 31 therein.
  • the numbers 2, 3 and 4 indicated by an arrow 32 in FIG. 3 are the same numbers 2, 3 and 4 indicated by an arrow 32" in FIG. 1.
  • a printing mechanism comprising: a frame; a rod rotatably mounted on said frame parallel to a printing line, said rod having a cylindrical outer surface with a helical groove therein; a typewheel rotatable on said rod, said typewheel having a projection extending into said groove; first means mounted on said frame to cooperate with means mounted on said typewheel to rotat e said typewheel in a predetermined direction continously at a constant speed relative to said frame; second means mounted on said frame, said second means being selectively operable to rotate said rod in said predetermined direction at 'an angular velocity greater than that of said typewheel; third means mounted on said frame, said third means being selectively operable to rotate said rod in said predetermined direction at an angular velocity equal to that of said typewheel whereby, when said third means is operable, no movement of the typewheel along the rod occurs while when the second means is operable the typewheel feeds to a new position; fourth means mounted on said frame, said fourth means being selectively operable to brake said rod thereby causing
  • said first means includes a first pinion fixed to said typewheel, said rod and said first pinion having the same rotational axis, a carriage slidable over said rod in a fixed angular position therearound relative to said frame, said typewheel being rotatable relative to said carriage but always movable therewith in the direction of said axis, a second pinion rotatably mounted on said carriage in mesh with said first pinion, a third pinion rotatably mounted on said frame in mesh with said second pinion, said first and second pinions having thicknesses at leastan order of magnitude less than the thickness of said third pinion.
