RESERVOIR ATTACHMENT FOR PENS.

To all whom it may concern:

Be it known that I, TErsUsABURo ATA- NABE, a subject of the Emperor of Japan, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Reservoir Attachments for Pens, of which the following is a specification.

The invention is an ink fountain for pens.

It comprises a cup for containing a supply of ink, which cup is secured upon a rod with its concavity facing the inner side of the pen and near the nib thereof. A lip on the lower edge of the cup is in proximity to the pen surface. During the act of writing, the nib of the pen is pressed away from the lip, so that the ink can flow downward from the cup to the pen. point. The rod carrying the cup is detachably secured directly to the pen by means of a spring clip, provided with operating arms and having loops which engage with the edges of the pen. The cup, rod and clip form a compact and simple device which may be separately sold, and applied to any ordinary steel pen. The cup is filled with ink after it is in place on the pen by dipping it in the ink.

In the accompanying drawings-Figure 1 is a perspective view of my device applied to a pen held in an ordinary holder. Fig. 2 shows my device separately and in perspective, and Fig. 3 shows my device in end elevation applied to the pen which is shown incross section.

Similar numbers of reference indicate like parts.

1 is an ink holding metal cup supported upon a rod 2, which rod is headed at its end and passes through lugs 3 on a pair of metal clips 4:. Said clips have their extremities 5 bent to form loops to receive the edges of the pen 6. Upon the rod 2 is a helical spring 7 which has protruding ends 8 bearing upon Specification of Letters Patent.

Serial No. 650,948.

the clip arms and normally tending to force the extremities 5 toward one another. By compressing the operating arms 9 of the clip, the extremities 5 are separated, so that the edges of the pen can be inserted in the loops 3 on said extremities. The spring 7 in contracting holds the clip 4; in place on the pen.

The ink holding cup 1 is adjusted with its concavity toward the pen, and so as to cover the usual opening 10 in the pen body. A lip or extension 12 on the rim of the cup then lies in proximity to the pen surface near the nib.

The pen is dipped in ink in the usual way to till the cup 1. In writing, the pressure on the nib separates the pen slightly from the lip 12, so that the inkcan run from the lip to the pen point. In order to facilitate the flow of ink, recesses 11 may, if desired, be made in the edges of the lip.

The pen is here shown held in a holder 13 of well known form.

I claim:

1. An ink fountain for pens, comprising a cup, a supporting rod therefor, a spring clip on said rod, having loops for engaging the edges of the pen, and operating arms on said clip.

2. An ink fountain for pens, comprising a cup, a supporting rod therefor, a clip formed of two members pivoted on the end of said rod and having loops for engaging the edges of the pen, a helical spring on said rod engaging with said clip members, and operating arms on said members.

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