Definitions

  • My present invention relates to the general art of writing pens and, more particularly, to a pen point which, because of its construction, may probably best be termed a revolvable-ball-point pen.
  • a pen point which, because of its construction, may probably best be termed a revolvable-ball-point pen.
  • a large number of pens have been put on the market during the past fifty years, in which the actual writing point is a ball of small size, normally in the neighborhood of th of aninch in diameter and which is backed up by a conical shaped reservoir of ink, usually an absorbent pad of some order, or it may be the thicker ink Where no pad is required, but in each instance the upper surface of the ball picks up a quantity of ink and then, as it rolls on the paper in Writing, deposits the ink on the paper so that a legible ink line results. Under most conditions, such pens are quite satisfactory, but are expensive in construction and usually the sacrifice made for the long non-filling period is counterbalanced by other
  • the principal object of my present invention is to provide a pen point of conventional style and type which can be used in a conventional fountain pen holder and still will give the user the ease of writing which characterizes the revolving ball type of pen point.
  • a further object of my present invention is to provide a pen point having a revolvable ball as the writing tip, which is of such a structure that it may be substituted in a fountain pen of conventional style and can thus feed from the ordinary fountain pen reservoir or it may be employed Further objects, advantages and capabilities will be apparent from the description and disclosure in the drawings, or may be comprehended as inherent in the device.
  • Fig. 1 is a perspective view showing my improved type of ball tip pen point
  • a further object of my present invention is to provide a pen point employing a ball writing tip, in which special means are provided to insure this smooth flowing of ink down to the writing ball.
  • Fig. 2 is a longitudinal sectional view through the pen of Fig. 1;
  • Fig. 3 is a cross sectional view, on an enlarged scale, showing the manner in which the ball engages the writing surface and showing the angle of the pen as being that conforming to the usual practice;
  • Figs. 4 and 5 are cross sectional views along similarly numbered lines of Fig. 2;
  • Fig. 6 is an alternate form of construction of my ball tip writing pen.
  • the numeral 8 designates my pen point generally. This may be made of any form ofmaterial now found suitable for forming a pen point; preferably, it should be of non-corrosive material, of which type many metal alloys are in quite common use. It can of course be made, in the least expensive style, out of steel.
  • the general shape and cut of the pen point follows the form which through years of trial have been found to be generally the most satisfactory, and is substantially as shown in Fig. 1, in which the body portion is reduced to an arcuate form at I0 so that it will fit into the usual pen receiving recess in pen holders.
  • the body is then swelled out to its extreme breadth at l2 where cuts are made so as to provide the point section I4.
  • An ink flow cut or passageway I5 is provided which,-in my present structure, is not to assist in the structure of the point but solely for its primary purpose of providing an ink flow channel, and a secondary purpose which will be subsequently explained. This cut extends down to the ball but not to the extreme end of the nib except in the modified form.
  • the tip portion of the pen is formed as illustrated in Fig. 3, so as to provide a spherical seat for ball l9 and should extend downwardly slightly below the center of the ball and be crimped or swedged to always grip or retain the ball in position and thus prevent it being dislodgedand lost.
  • the under surface, as 20, of the ball receiving cup which will be substantially a circle, should be dressed oif at such an angle that it will be at all points equidistant from the writing surface 3 when the pen is held at the normal writing angle. This is illustrated in Fig. 3.
  • I provide a movable feeding unit 22. This is constructed by providing a blade portion at 23 which is loosely mounted within the ink feed slot I5. I further provide a guiding and stop member 24 which is rod-like in its structure and has at its upper end a down turned portion 26.
  • a movable feeding unit consisting of the blade like portion 23 and the connecting guiding and stop member '24, which are similarly disposed as in the preferred arrangement and function in the same manner.
  • a writing pen point consisting of: a pen securing portion having an arcuate form, a body portion tapering outwardly from the securing portion and provided with oppositely disposed arcuate cuts which provide a blunt end, a semispherical ball-seat formed in said blunt end, a ball revolvably seated in said spherical recess, a rim formed as a continuation of said spherical seat adapted to extend below the center line of said ball and to be crimped or swaged at the outer margin so as to provide a retaining means for said ball, a feeder opening centrally positioned in the body of said pen, a support member for said pen, disposed beneath said pen; a stop slot on the upper surface of said support member, adapted to act as an ink reservoir, an ink passageway having spaced side walls disposed co-axially with said pen body and extending from said stop slot to the writing end of said pen, a movable inkfeeding unit disposed below said passageway and
