IMPROVEMENT IN PENS.

Specification forming part of Letters Patent No. 152,141, dated 511116 15, 1874 applicati@ lefl April 30, 1874.

To all whom it may concern:

Be it known that I, JosIAH MASON, of Bir-V min gham, in the county of IVarwick, England, have invented a new and useful Improvement in Pens and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part ot' this specification, in which drawing- Figure l represents a front view of one of my pens. Figs. 2, 3, 4, and 5, respectively, are modifications ot' the same.

Similar letters indicate corresponding parts.

This invention relates to certain improvements in metallic pens; and consists in the arrangement, upon the nibs of the pen and at a short distance from the point, of side cheeks or enlargements, for the purpose of arresting` the flow of ink on such sides and on the external surfaces ot' the pen, the ink being supplied to the. point oi' the pen through the slits thereof, in such amanner that a uniform or nearly uniform ow of ink is produced, and the danger of blotting by reason ot' an overcharged pen is averted.

In the drawing, the letter A designates a slip metallic pen constructed according to my invention. a ay are its nibs or tips, the outer sides of which are expanded or enlarged, so as to form cheeks or scallops b b. These nibcheeks or enlargements are at a short distance from the point ofthe pen, and may have the semicircular form here represented, or any other chosen form or shape. rIhe extreme points of the nibs a a-,that is, the sidesA thereof beyond the cheeks b b-may either be parallel or slightly inclined to one another. Then the pen is dipped into ink the ink is principally retained above the nibeheeks b b,

whereby the ilow or supply ot' ink to thev forms or modifications of pens constructed acx cording to my invention. In these pens auxiliary side cheeks b b are used in combination with the nib-cheeks b b just described. These auxiliary cheeks b b form a part ot' the slip or shank A of the pen. In Fi g. 5 the nib-cheeks b b also form a part of said slip or shank, instead of being on the side of the nibs, as in the other figures-that is, the shank ot' the pen is prolonged downward to near the point of the nibs, as represented in the drawing. In Figs. l and 2 the central slit of the pen passes beyond the nib-cheeks b b, opening into an enlarged slit, e. In Fig. 3 a hole, d, is punched midway between the nib-cheeks b b, into which hole the aforesaid slit opens or vanishes. In Fig. 4 the slit vanishes into the nib-cheeks b b, and each of these cheeks is provided with a hole, d. In Fig. 5 the auxiliary cheeks b b are each provided with a hole, as shown, the end or nib cheeks remaining unpunched, while lthe central slit passes beyond the whole series of cheeks.

.By the formation of side slits e e coincident with thel side outline of the nibs a a, said nibs of the pens, Figs. 2, 3, 4, and 5, are made elastic, and may be made with or without the nibcheeks b b, as the greater portion ot' the nibs is thus situated between and supported by the auxiliary cheeks b b', the latter constituting reservoirs .t'or holding the ink, which is fed uniformly to the nibs in writing.

The pens move with great smoothness over the paper, and they are not liable to drop the ink or blot and spirtle the paper, as is coinmon to ordinary steel pens.

These improvements are applicable also to barrel pens.

W'hat I claim. as new, and desire to secure by Letters Patent, is-

A metallic pen constructed with one or more pairs of cheek-nibs, b b', substantially as described, for the purpose described.

JOSIAII MASON.
