Definitions

  • This invention relates to an improved tool for spinning the wall of a recess formed in the nose piece of a writing instrument to facilitate retention of a ball therein for universal rotation.
  • Writing instruments provided with ball tips comprise a nose piece generally having a conical external surface and an axially disposed recess in the end of each nose piece, a ball being rotatably held in such recess with a portion of its surface extending beyond the end of the nose piece.
  • a suitable channel or passageway supplies ink to the enclosed surface of the ball from a cartridge or ink reservoir. As the ball rotates during writing it carries the ink from its enclosed portion to the external position and applies the ink to the surface upon which the ball is moved.
  • a very similar construction and mode of operation are also employed when the ball is supplied with writing compositions other than ink.
  • the tip portion of the nose piece is swedged or forcedinwardly against the ball to retain it within the recess. Thereafter the tip is subjected to a spinning operation which apparently work hardens the metal wall of the recess causing it to spring away from the ball and thereby permit free universal rotation of the ball within the recess.
  • the spinning operation must be carried out very accurately so as to retain the ball within its seat and still provide an adequate clearance for the ink or writing composition carried by the surface of the ball. The clearance should be uniform around the ball so as to insure free rotatability of the ball.
  • the spinning tool comprises two discs, each mounted for free rotation about an axis displaced from the main axis of the chuck, such main axis being coincidental with the axis of the nose piece and recess.
  • the nose piece is maintained stationary and the rotating chuck causes the spinning discs to apply a rolling pressure to the metal adjacent the end of such nose piece.
  • a spinning tool comprises a chuck adapted for rotation about its axis and carrying eccentrically in its face a spinning disc and a concentric spinning ring, the disc and ring being mounted for rotation relative to the chuck and to each other.
  • the spinning disc and ring are each provided with coadjacent Spinning edges or surfaces lying in a common plane transverse to the axis of rotation of the chuck, the spinning surface of the disc being convex, in plan, and that of the ring concave.
  • the spinning disc and ring are so arranged that the center of rotation of the chuck and a nose piece positioned between the coadjacent spinning surfaces will be coaxial during a spinning operation.
  • a spinning tool according to the present invention has several advantages, among them being the 2,818,828 Patented Jan. 7, 1958 ability to use larger bearings and the fact that the tool is substantially self-centering, permitting the stationary nose piece to more readily adapt itself to the tool, thereby permitting the tool to apply uniform rolling pressure on diametrically opposite sides of the nose piece.
  • the coadj'acent convex and concave spinning surfaces also provide an improved spinning action which facilitates spinning and greatly reduces the number of improperly processed articles.
  • the spinning portions of the tool of the present invention are more readily changed, adjusted and appear to have greater .life.
  • Fig. 1 is an axial section (certain parts being in side elevation) of one form of tool made in accordance with the present invention
  • Fig. 2 is a bottom view showing the working face of the tool.
  • Fig. 3 is an enlarged detail of Fig. 1, showing the spinning contact of the tool with a writing tip.
  • the tool itself comprises a chuck having a rear face 11 provided with axially and rearwardly disposed means for connecting the chuck to a suitable driving means, such as, for example, the threaded end of the shaft 12.
  • the front or working face is eccentrically counterbored as indicated at 13 and a spinning disc 14 is rotatably mounted within the counterbore 13.
  • the spinning disc 14 may be provided with an elongated stem 15, suitable spaced bearings 16 and 16 spaced by rings 17 being positioned in the bore 13 with a pressed fit so as to rotatably hold the spinning disc 14 and its pin shaft on an axis of rotation eccentric the axis of drive shaft 12.
  • the extending external cylindrical surface of the elongated pin shaft 15 may be provided with a sleeve 18 having a face 20 adapted to receive ball bearings 21 and 21 and thereby mount an eccentric spinning ring 22 having the upward flange 23, permitting the spinning ring and its flange to freely rotate on an axis coincidental with the axis of the spinning disc 14.
  • the working faces of both the spinning disc 14 and spinning ring 22 may assume various contours.
  • the working edges are each provided with a rounded surface such as the surface 24 of the spinning disc 14, such rounded surface merging the downwardly facing conical surface 25 and the upwardly facing conical surface 26.
  • the rounded surface 24 lies in a plane transverse to the axis of rotation of the disc 14; the angle of the lower face 25 to such transverse plane is preferably smaller than the angle of the surface 26.
  • the angle of the surface 25 to such transverse plane may be on the order of or l0%) whereas the angle of the conical face 26 to such transverse plane may be from to when the device is used for setting balls in the nose pieces of writing instruments.
  • the spinning ring 22 is preferably supplied with a similar rounded working edge or surface 24' joining inclined lower and upper surfaces 25 and 26'.
  • the entire chuck when the entire chuck is brought down against a substantially stationary writing tip 30 provided with a nose piece having the external conical surface 31, a recess 32 in such nose piece and a ball 33 seated therein, the rounded edges 24 and 24 of the spinning disc and spinning ring respectively will contact the exterior surface of the wall of the recess. Rotation of the entire chuck will permit the spinning ring and the spinning disc to rotate and roll around the surface of such nose piece, suitably working and sprin is ing the metal so as to provide a sufficient clearance to permit rotatability of the ball Within the recess.
  • the chuck may additionally be provided with a suitable counter weight 19, which may take the form shown.
  • the overall operation of the device may best be understood by reference to Fig. 2.
  • the center of rotation of the chuck 10 is coaxial with the nose piece 34
  • the Spinning disc 14 may be rolled about the nose piece, in either direction, depending upon the direction of rotation of the chuck.
  • a clockwise rotation of the chuck as indicated by the arrow 40
  • a sliding frictional engagement between the nose piece and the spinning disc' will produce clockwise rotation of the spinning disc relative to the nose piece (directional arrow 42).
  • the working surface 24 of the ring presents a concave working surface, in plan, which contacts an appreciably larger surface area of the wall of the nosepiece than the covex, smaller diameter surface 24- of the spinning disc 14. It has been found that the larger concave surface of the external spinning ring improves the spinning operation, expedites it and reduces the number of improperly spun articles which are normally encountered in commercial production. Moreover, the sloping coadjacent surfaces, each curving to a point coaxial with the axis ofrotation permit the too-l to be substantially self centering on the nosepiece, thereby virtually eliminatinga particular troublesome problem heretofore facing the art.
  • the present invention provides for the first time a spinning tool that is substantially selfcentering on the nosepiece of a ball pen point, primarily as a result of alignment of concentric sloping concave and convex surfaces of a spinning disc and ring with the center of-rotation of the tool.
  • the madjacent concave and convex spinning surfaces permit an unusually efficient working or spinning of the metal 4. serving to effectively free the ball for universal rotation in the point.
  • the spinning ring and disc may be mounted in the tool as a unit, facilitating replacement of the entire spinning attachment as needed for effective use of the tool.
  • a tool for spinning the wall of a recess formed in the nosepiece of a writing instrument to facilitate universal rotation of a ball therein comprising: a chuck having axially and rearwardly disposed connecting means; an eccentrically disposed spinning disc-rotatably mounted in the face of said chuck; a spinning. ring rotatably mounted by the chuck and concentrically surrounding the spinning disc, said spinning disc and said spinning,
  • ring being provided with spinning surfaces lying in a common plane transverse to the axis of rotation of the chuck, and 50 arranged in the face of the chuck that a center of rotation of the chuck and a nosepiece positioned between said spinning surfaces Will be coaxial during a spinning operation, the spinning surface of the disc being convex and that of the ring concave.
  • a tool for spinning the wall of a recess formed in the nose piece of an element such as a writing instrument to facilitate universal rotation of a ball in said recess comprising an eccentrically disposed spinning disc rotatably mounted in the face of a rotatable chuck and concentrically surrounded by a spinning ring mounted for rotation with respect to the chuck, said spinning disc and spinning ring being so arranged in the face of the chuck that a nose piece positioned between the spinning surfaces of said disc and ring will be coaxial with the center of rotation of the chuck during a spinning operation.
