Upon instituting the use of the pen tion and showing a modified construction the ink carried by the core will flow by way of grooves 18 and 19 to the writing point 11- where it is evenly delivered to the material upon which the pen is operated. It will be noted that as the bore of the tubular member is circular in cross section at the writing point 11 the pen during use will trace a line of constant width and evenness irrespective of the direction in which the pen is operated.

ing as indicated at 21 in Fig. 9.

In the -modified form of the invention illustrated in Figs. 6, 7, 8 and 9 the bore of the tubular member 10 at the writing end thereof has the form of an elongated openticular form of opening at the writing end of the tubular member 10 will enable certain desired shading to be efiected during the operation of lettering. As the result of the and this relative position of the core is, de

termined by providing same with a laterally projecting .pin 22 which seats in a recess 23 in the tubular member when the core and tubular member are disposed in proper assembled relation. In other respects the form of pen illustrated in 6, 7, 8 and 9 is similar to that illustrated in Figs. 1, 2, 3, 4 and '5 both as to structure and operation.

It will be noted that the core 16 is provided with fiatfaces 22' at each side of the openin 17 so as to not engage the interior wall 0 the tubular member 10 during the This parinsertion of the core into the tubular memfaces 22"alsoserve to orm an air inlet and eflect an even and free flow of the ink through the .writing point.

What is claimed is:

1. A pen formed of a tubular member, one end of which constitutes a writing point and an ink carrying core removably mounted in said member, said core comprising an integral head having a transverse opening therethrough for receiving and holding ink, and further provided with longitudinal grooves on its side face communicating with said transverse opening through the end of the core adjacent the writing point.

2. A pen formed of a tubular member, one end of which constitutes a writing point an an ink carryingcore removably mount ed in said member, said core comprising an integral head having a transverse opening theret-hrough for receiving and holding ink,

and further having flat side portions at the terminals of said openings, and means for conveying ink from the opening to the writing point. 1

In testimony whereof, I aflix my signature in presence of two witnesses.
