WILLIAM WORTH, OF SAN ERANLGISQO, CALIEQBNIAf LETTERING-PEN.
Specification of Ii'etters Patent.
Patented July 4, 1916.
Application filed August 24, 1915. Serial No. 47,023.
To all whom it may concern:
Be it known that I, WILLIAM E. WORTH, a citizen of the United States, residing in the city of San Francisco and State of California, have invented certain new and useful Improvements in Lettering-Pens, of which the following is a specification.
My invention 7 relates to lettering pens, and more particularly to certain improve ments in lettering pens of the character shown and described in my United States Patent No. 1,136,196, issued to me April 20, 1915. I have found in experimenting with these pens that a lettering pen which has a round split nib with a flat circular marking surface, produces a mark which is slightly heavier at the initial or starting place, or where the pen first touches the paper. This is due to the fact that the flat writing surface is covered with ink and as soon as it touches the paper this ink is pressed outwardly around the edges of the circular writing surface, thus making a mark larger in diameter than the diameter of the pen. As the pen is moved, the mark made is only as wide as the diameter of the pen. I have discovered that a lettering pen of triangular form in cross section and having a flat writing surface of triangular form, eliminates this objection. This is due to the fact that a triangular writing surface has less contacting area than has a round or circular writing surface of the same diameter.
Therefore, when a pen of triangular form in cross section first engages the paper, the ink thereon will be pressed outwardly from the sides of the pen in the same manner as in the case of the round flat writing surface, but as the sides of the writing pen are straight and lie within the area of the greatest diameter of said pen, the mark is no heavier than this extreme diameter, and as the pen is moved, in any direction, the mark made is of the same uniform width, corresponding to the greatest diameter of said triangular-shaped pen nib, which is, of course, the same as the diameter of a circular pen of the same size. This would not be true of a pen having a square form in cross section for the reason that when the pen was moved sidewise it would make a mark equal in breadth to the dimension of shown a lettering pen of the same general construction as that shown in my patent, above referred to, that is, a form of pen, different sizes of which can be interchangeably used with the same stock, or handle, and with the same pen holding device having the ink reservoir therein.
In the drawings, Figure 1 is a flat view of a pen embodying my invention looking at it from the under side; Fig. 2 is an edge view of the pen, also showing the end of the split nib'of triangular form; and Fig. '3'is an enlarged end View of a pen nib of triangular form, showing also in light dotted lines the area of a round nib of the same diameter.
The heart of my invention, however, is a split pen nib of angular form in cross section, as distinguished from a pen of circular form in cross section, whereby to provide a flat writing surface of less area than has a pen having a round or circular writing surface, and which will, nevertheless, make a mark of uniform diameter in Whichever direction it is moved upon the paper.
What I claim to have invented and wish to protect is broadly set forth in the following claims forming a part hereof.
I claim:
1. A pen of the character referred to hav ing two nibs terminating in a flat marking surface which is an equilateral triangle in form.
2. A pen of the character referred to comprising two nibs of triangular form in cross section and terminating in the same plane in a fiat marking surface which is an equilateral triangle in form.
3. A lettering pen of the character referred to, comprising a body, or shank portion, terminating in writing nibs having formed thereon a flat writing surface of equilateral triangular form, substantially as county, Oregon, this 7th day of August, described. 1915.
4. A lettering pen having its contacting, 0r marking, surface fiat and of equilateral triangular form, for the purpose referred to.
In Witness whereof, I have hereunto signed my name at Portland, Multnomah WILLIAM E. WORTH.
Witnesses:
I. M. GRIFFIN, E. L. SHERMAN.
