FRANCIS KAYSER, OF PHILADELPHIA, PENNSYLVANIA.

ATTACHMENT FOB PEN-NIBS.

Specification of Letters Patent. Patented July 20, 1915.

Application filed May 26, 1914. Serial No. 841,101.

To all whom it may concern Be it known that I, FRANCIS KAYsnR, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Attachments for Pen-Nibs, of which the following is a specification.

An object of the invention is to provide a simple attachment for pen nibs and which will permit of writing a longtime with the nib without redipping the same in the ink in that the attachment, constituting a reservoir or ink holding member, will, after the nib is initially dipped in the ink, supply ink to the writing end of the nib from the reservoir or ink carrying member.

The invention contemplates, among other features, the provision of an attachment which substantially converts the usual pen nib into a fountain pen in that it provides a reservoir for holding the ink and whereby the ink, under the influence of capillary attraction, is fed to the writing end of the nib, the device consisting of a single piece of material, can be readily bent to form the ink supplying reservoir and means for holding the device upon the nib of the pen.

The device will preferably be made of metal, although it will be understood that it can be made of any material and preferably one that will not be susceptible to the corrosive action of ink. I

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a perspective view of the nib holder showing my attachment applied to the nib; Fig. 2 is an enlarged vertical longitudinal sectional view taken through a nib having my device applied thereto; and Fig. 3 is a vertical transverse sectional view taken through the structure shown in Fig. 2.

Referring more particularly to the views, I disclose a holder 10 in which is suitably arranged the usual pen nib 11, said pen nib in cross section being concave, the same as the usual pen nib generally used. The nib attachment consists of'a single piece of ribbon-like material indicated by the numeral 12 and which is bent at substantially its medial portion to form a frusto-conical reservoir or ink holding member 13 having its smaller open end adapted to lie upon the face of the nib and adjacent to the inner end of the usual slit 14 extending longitudinally in the nib. The ends of the piece of material after the formation of the reservoir 13, are bent around the face or top of the nib to form attaching members or flanges 15 which pass around the edges of the nib and engage the under side thereof and rigidly hold the device upon the pen nib as shown.

Now when the nib is dipped in the ink it will be apparent that the reservoir 13 will be filled with the fluid and as the ink initially received upon the pointed end of the nib is used up, the ink in the reservoir will, by capillary attraction, be fed into the slit 14 and thence flow to the point of thenib so that the user can write a great deal longer with a nib having the attachment described than if the ordinary nib without the attachment were used. Thus the device is in the nature of a fountain pen nib attachment in that it will supply a quantity of ink to the nib for a long time without replenishing the nib with a new supply of ink. It will be apparent that the device can be sold separately to be attached to the nib by the purchaser or that it can be made up in connection with the ordinary pen nibs now generally used and sold in combination with the nib as a unitary article.

Having thus described my invention, I claim:

As a new article of manufacture, an attachment for-pen nibs consisting of a single 1 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, .Washington, D. 0.?
