PERCY SWAINE, OF SHERBROOK, QUEBEC, CANADA.

PEN.

Application filed. December 2, 1914, Serial No. 875,158.

T 0 all to 710m it may concern Be it known that I, PERCY SWAINE, a sub ject of the King of England, residing at Sherbrook, in the Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Pens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pens.

The object of the invention is to provide a pen embodying an improved construction whereby same will trace a line of uniform thickness and will move smoothly over the material being operated upon.

A further object of the invention resides in the provision of a pen which can be used in connection with either an ordinary pen holder or with a fountain pen, the essentials of the invention being in no way changed in adapting the pen for one use or the other.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which Figure 1 is a perspective view of a pen constructed in accordance with the inven tion and adapted for use in connection with an ordinary pen holder;

Fig. 2, a view similar to Fig. 1 showing the pen adapted for use in connection with a fountain pen, a fragment of the barrel of the latter being disclosed;

Fig. 3, a plan view of the pen before the point has been shaped, and

Fig. 1, a longitudinal section of the pen shown in Fig. 1.

Referring to Figs. 1, 3 and 4 the pen is shown constructed from a tubular, member A having one end cut away to form a point 10 which latter is slitted longitudinally at 11 to form sections 12 and 13. By cutting away the member A to form the point 10 a tongue 14: is produced which is bent inwardly after being suitably shaped so as to almost close one end of the tubular member A, sufiicient Specification of Letters Patent.

Renewed August 14, 1919. Serial No. 317,634.

space being left between the edge of the tongue and the inner side of the point 10 to permit proper feed of the ink to said point. In this way the tubular member A forms a reservoir 15 in which a relatively large amount of ink may be stored and gradually fed to the mint 10. The end of the tubular member opposite the point 10 is cut away to form a transversely curved shank 16 whereby the pen may be readily associated with an ordinary pen holder. In forming the point 10 the sections 12 and 13 are left with enlarged portions 17 and 18 respectively, said portions being substantially semi-circular and opposed. The inner ends of the portions 17 and 18 extend contiguous to a limited extent with the outer edges of respective sections 12 and 13. To complete the formation of the outer end of the point 10 the portions 17 and 18 are bent outwardly so as to lie in the same plane with each other and at an angle to the longitudinal axis of the pen. By providing the flat portions 17 and 18 at the outer end of the point 10 it will be obvious that the pen will trace a line of uniform thickness and operate smoothly over the material being written upon, such a construction being particularly advantageous in the process of lettering.

In adapting the pen for use in connection with fountain pens the member A is threaded as at 19 just inwardly of the shank 16 so that same may be screwed into the barrel 20. When the pen is so utilized it will be obvious that the tongue 14: provides the necessary feed.

What is claimed is 2-- A pen including nibs each having at its lower end a segmental extension forming a tip which tips lie in a common plane at an angle to the nibs, the curves of the tips extending from a common point in advance of the lower ends of the nibs to points to the rear of the nibs whereby bearings are provided fore, aft and at the sides of the nibs to oppose rising of the forward ends of the tips from a writing surface under the influence of slightly increased writing pressure.

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