ATTACENT FOR FOUNTAIN PENS.

Application filed June 10, 1921. Serial No. 76,412.

To all whom it may concern:

Be it known that I, EMIL Lenses, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Attachments for Fountain Pens, of which the following is a specification.

Fountain pens, as usually constructed, have their nibs or en portions rigidly or permanently secured in the barrel, so that they are not readily changeable.

When these pens are made sufioiently flexible for ordinary writing purposes they are not adapted for making duplicate copies as with carbon sheets. The present invention relates to an adjustable attachment which may be readily applied to fountain pens for stifiening the nibs thereof, so that a single pen may be used for various purposes.

The objects of this invention are to provide an attachment for stifiening the nibs of a fountain pen; to provide a longitudinally and laterally adjustable stiffener for fountain pens; and to provide such an improved construction as will be described more fully hereinafter.

In the accompanying drawings illustrat ing this invention;

Figure 1 is a side view of a fountain pen with my attachment applied thereto.

Figure 2 is an enlarged detail view showing the attachment in section;

Figure 3 is a plan view;

Figure 4 is a cross section taken on the line 4-4: of Figure 3;

Figure 5 is a perspective view of the at tachment; and,

Figure 6 is a perspective view showing slightly modified form. I

As shown in these drawings, the attachment comprises a clip or band 7, which is adapted to fit around or engage with the pen .8 and its support or feeding member 9. This clip is preferably split on one side, as .indicated at 10, so that it may be easily slipped over the parts with which it engages. The lower part of the clip may be made substan 'tially flat, as shown at 11, and is joined to the upper part 12 by an outwardly curved portion 13, which increases the resiliency and permits the clip to be adjusted sidewise or laterally, so that it will fit fountain pens of different widths. This clip has a forwardly extending strip or projection 14,

which is adapted to engage with the upper surface of the nibs, in order to reinforce or stifien the same when desired. This pro'ection is preferably curved a little more t an the pen, as shown at 15 so that the extreme end thereof will rest on the upper surface of the pen. The point'of this projection is also preferably a little wider than the pen point, so as to insure proper engagement therewith. In the modified form of construction, shown in Figure 6, the upper portion of the clip and the central portion of the projection are cut away as shown at 16 to expose the upper surface of the pen. This may be desired in connection with some pens in order to facilitate the-flow of the ink and to prevent it from becoming dry between the pen and the attachment. A thumb piece 17 is also provided for convenience in sliding the attachment back and forth. When the pen is to be used for manifolding purposes, as for making carbon duplicates of bills, or the like, the attachment is pushed forwardly so that the point 14 will press against the nibs ofthe pen and stifi'en the same. In this manner an ordinary foun tain pen may be made sufficiently stifi, so that one or more carbon copies may be made. When the fountain pen is to be used for oidinary writing, the attachment is drawn back to the position shown in Figures 1 and 3 and the nibs will then be unsupported and free to function in the usual manner.

Having thus described my invention, of which however, I do not Wish to limit to the exact construction herein shown and described, except as specified in the following claims. what I claim is:

1. The combination with a fountain pen having the usual barrel and feeding member, of a clip adapted to engage with the pen and said feeding member, said clip having a forw'ardly extending projection adapted to bear against the nibs'of the pen, the clip being slidably mounted and adapted to be adjusted longitudinally with respect to the pen.

2. The combination with a fountain pen having the usual support or feeding member for the pen, of a clip slidably engaging with the pen and adapted to be adjusted longitudinally, said clip having a pointed extension bearing on the nibs of the pen, as and for the purpose described.

3. Anattachment for fountain pens, comprising a clip formed of resilient material, and having a fiat under portion adapted to are 10 position.

engage with the supporting part of the pen, and a curved upper portion adapted to engage with the upper surface of the pen, said parts being connected by an outwardly curved portion, whereby the clip may be adjusted laterally for difl'erent sized pens, said clip having a projection finger, the outer point of which is adapted to bear against the nibs of the pen when the clip is in adjusted meepo'a ed to engage with the nibs of the pen to stiffen the same, the upper portion of the clip and the tongue being cut away to'form an opening, and a thumb piece for said clip.

EMIL LEESER.
