Definitions

  • the present invention has for its object to overcome said difliculty and consists in this that the depressed portion of one of the point halves which is parallel to the plane of tangency t0 the back of the nib is situated nearer to said plane of tangency than is the depressed portion of the other point half.
  • FIG. 1 is a plan v1ew of a pen nib constructed in accordance with this invention.
  • Fig. 2 is a side-elevation, with part in section. of the nib.
  • Fig. 3 is an enlarged cross-section taken on the line 33 of Fig. i.
  • Fig. 4 is an. enlarged cross-section taken on the line 4-4 in Fig. l.
  • l, 2 denote the two point halves of the nib, formed at 3, and 4. respectively, with depressed portions parallel to the lane of tangency to the back of the nib, said plane of tangency being indicated by the dotted line 5, Figs. 3 and l.
  • the said depressed portions have for their purpose to secure a soft flexibility of the nib while at the same time preventing the point from scratching the paper when in use.
  • the depressed portion 3 is so shaped as to allow the corresponding point half of the 1921. Serial N0. 452,456.
  • said portion 3 is parallel to the said plane of tangency to its whole extent. Furthermore, the depressed portion 3 is situated nearer to said plane of tangency than is the port-ion 4.
  • the depressed portion 4 parallel to the said plane of tangency is of less rearward extension than the depressed portion 3 and is continued rearwardly by an outwardly inclined plane portion l, Fig. 3, thereby enabling the corresponding point half to yield both upwardly and outwardly.
  • the said construction has proved reliable as to the avoidance of scratching of the paper, inasmuch as it is well adapted to the flexibility of the nib points as is required when the writer holds the nib directed more or less forwardly or rearwardly.
  • the point half yielding upwardly but not outwardly may be situated on the right or left hand side, as the one construction or the other may be preferred according as the writer is in the habit of keeping the right hand side point half or the left hand side point halt nearest to the paper in writing.
  • a pen having its nib formed with depressed porticns on its back at both sides of the slit, said depressed portions having a cross section parallel to the plane of tangency to the back of the nib, one of said portions being situated nearer to said plane than the other portion.
  • a pen having its nib formed With depressed portions on its back at both sides of the slit, one of the depressed portions being continued rearwardly by a laterally inclined surface, the other depressed portion having throughout its length a crosssection that is parallel to the plane of tangency to the back of the nib.
