Definitions

  • An inking roller assembly includes an inking roller having a central core with conical ends, The assembly has a casing for the roller with a lateral opening to receive the roller.
  • the shaped apertures extending from the opening terminate in bearing shells having conical surfaces for holding the conical ends of the core, so that the roller is held in a position out of contact with the walls of the casing.
  • This invention relates to inking roller assemblies of the type incorporating an inking roller for use in a writing machine, and the invention is particularly directed to the provision of such an assembly in which a covering for the inking roller may be readily separated from the inking roller.
  • inking rollers i.e. rollers of a permeable material filled with ink.
  • ink rejecting foil of various kinds, for example, plastic foil.
  • this type of packaging has been found to be unsatisfactory.
  • auxiliary lateral disks between which the inking roller is held.
  • the disks must be removed by hand prior to inserting the inking roller into the machine. This procedure constitutes a substantial source of soiling.
  • the lateral disks are not removed since they may be inserted into the writing machine along with the inking roller.
  • a casing for an inking roller.
  • the casing has a lateral opening which may be closed by any type of cover member.
  • the casing is also provided with V-shaped apertures extending in the walls of the casing from the open side inwardly generally to the middle points of the walls.
  • the inner ends of these apertures are formed as bearing shells for the roller itself.
  • the two bearing shells have inwardly facing marginal or rim enforcements which preferably extend in a conical manner relative to the central axis of the casing, i.e. the axis of the roller.
  • An inking roller is supported in the casing according to the invention in such a manner that it is free to contact at all points except for its rigid hollow core.
  • This core has conical end portions arranged for cooperation with said conical marginal reinforcements of the bearing shells, so that these conical ends of the core will snap into the conical bearing ends.
  • rollers are inserted into the respective machines together with the entire casing so that the hollow core is placed onto a bearing shaft or stud in the machine, whereupon the casing may be laterally removed without ever touching the inking roller itself.
  • FIG. 1 is a plan view of an inking roller assembly in accordance with one embodiment of the present invention
  • FIG. 2 is a cross-sectional view of the assembly of FIG. 1 taken along the section line 2-2;
  • FIG. 3 is a partial cross-sectional view of an inking roller assembly in accordance with another embodiment of the invention.
  • FIG. 1 is a plan view of a casing -1 having an open top, hereinafter referred to as a lateral opening.
  • V-shaped apertures 3 extend from the internal opening downwardly in a pair of opposite side walls of the casing. These apertures 3 are provided at their lower ends with reinforcing flanks forming bearing shells 4. The apexes of the apertures are preferably positioned so that the axes of the bearing shells are substantially at the mid points of the walls.
  • An inking roller 2, having a hollow core 5 and an ink soaked portion 12 is inserted in the casing l.
  • the hollow core 5 has ends extending out of the roller proper, i.e. beyond the inked portion 12. These outwardly extending ends of the hollow core 5 cooperate with the bearing shells 4 in such a manner that the inking roller may be snapped into position and securely held inside the casing without physical contact between the inked portion 12 of the roller and the inner walls of the casing, as shown at the points 6a, 6b and 6c.
  • FIG. 2 is a cross-sectional view into the casing from its internal opening.
  • FIG. 2 shows that the inked portion of the roller is free of contact from the inner walls of the casing as illustrated by reference numerals 7a, 7b, 7c and 7d.
  • the snap-in feature is obtained since the core 5 is provided at both ends with a conical chamfer or bevel 8 which fits into the respectively conical shape 9 of the bearing shells 4, so that the open ends of the core extend into the V-shaped apertures 3.
  • the conical chamfer of the bearing shells is shown in FIG. 2 to be concave (i.e. with the conical apexes outside of the casing), and the outer ends of the core 5 are shown to be convex for cooperation with the concave bearing shells, it will be appreciated that the arrangement can be the other way around provided that the walls of the casing are sufficiently flexible for snapping into the concave open ends of the core 5.
  • FIG. 3 illustrates it is seen that the conical surfaces 13 of the bearing shells 4 are convex and the conical surface M of the ends of the core are concave.
  • the inking roller may be easily removed from its strapped in position in the bearing by means of a simple tool such as a pencil, whereupon the inking roller may be placed onto a bearing stud or shaft in a writing machine.
  • the inking roller may be removed by simply compressing the lateral side walls of the casing as shown by the arrows 11 in FIG. 1 so that the side walls which comprise the bearing shells are slightly spread apart, whereby the bearing shells release core 5.
  • the illustrated assembly may be provided with a suitable cover of conventional construction for covering the lateral opening.
  • An inking roller device comprising a central roller core having conical end surfaces coaxial with said core, an ink roller mounted on said core, and a casing having a pair of flexible, spaced apart side walls and an open top to which said side walls extend, said roller and said core fitting into said casing through said open top, each of said flexible side walls having an aperture extending from the edge thereof adjacent said open top to terminate in a centrally located apex in the respective side wall, wherein the apertures of the two side walls are defined by aperture edges aligned with each other. a reinforced bearing shell around the apex of each aperture.
  • each bearing shell having a conical surface directed inwardly into said casing and merging into the respective aperture edges, said conical surfaces of the bearing shells being shaped and spaced to releasably receive the conical end surfaces of said core which is fitted between said conical surfaces of said bearing shells so that the conical end surfaces of said core engage the conical surfaces of said bearing shells with a snap fit due to said flexible side walls, the conical end surfaces of said core providing the only supporting surfaces of said core, whereby the conical surfaces on said bearing shells support said core within said casing in such a position that contact betweensaid ink roller and the walls of said casing is prevented.
