Application filed April 19, 1918. Serialll'oflzfmlw.

abuts against the open end of the holderor hollow handle of the. pen.

My object is to produce a device, efficient for the purpose of attaching the fountain pen to the clothing of the user,

when the fountain pen is not in actual use, which shall be made up of few parts, organized together securely yet wlthout the necessity of expensive working of the metal or hard rubber made up.

The device is made 117p of three parts,

parts of which the device is namely, a flexible metal clip, an outer cap and an inner cap, the outer cap being adapted, by means of screw threads on the barrel of the fountain pen and wlthin the open end of the cap, to engage the barrel;

the mner cap being adapted to fit within and engage the outer cap and the flexible metal clip being organized with the other parts as described and illustrated herein. In thedrawing: Figure 1 is a longitudinal central section of my combined cap and clip, in place upon the pen point endof a fountainpen;

Fig. 2 is an elevation of the cap, at an. angle 90 from that of Fig. 1;

Fig. 3 is an elevation of the inner cap; Fig. 4 is a perspective view of the metal clip I i c 0 Fig. ,5 is a view of the Split rmg. My invention, in its preferred form, 1ncludes a clip-member, C, having an oflset arm, at, and, at the free end of the arm, d, an odset toe, e. The outer cap A on one side is pierced by an aperture, a, which opens into the interior. of the cap at the inner face of the closed end of the outer cap. At a point upon the inner face of the closed end of the cap, in line wlth the aperture, a, is a recess, b, adapted to receive the teat, of the clip, when the parts Specification of Letters Patent.

are organized together. The arm, (Z, is

passed through the aperture, a, and the r toe, e, is inserted in the recess, 6-, the clip, C, lying longitudinally on the outer surface of the cap with its free end toward the open end of the cap. The inner cap, B, is forced into the outer cap until it, abuts againstthe aim, d, and secures the toe, e, in the recess, 6. In order to obviate the possibility of the clip disturbing the inner cap accidentally, prying it downward, when the parts are not locked together as when in use, as might be possible if the inner cap were merely frictionally held within the outer cap, I preferably provide a split ring connection between the two caps, the outer cap being provided witha groove 7) on its .inner surface and the inner cap being provided with a groove, 7), on its outer surface and a split ring, 7", seated between the caps and engaging the grooves b, b", to hold the two caps securely in relative position when the cap, B, is not engaged with the fountain pen P, by the screw threads, p. When the clip is in use the outer capis secured in place upon the open end of the fountain pen, so that the open end of the inner cap, B, impinges on the open end of the fountain and the inner cap is clamped between the end of the fountain and the parts at the closed end of the outer cap, securely holdin the toe, e, in the recess 2'), and holding the c ip in fixed position.

1 claim:

1. The combined cap and clip above described, made up of a metal clip upon the outside of the cap and extending longitudinally thereof perpendicular thereto, carrying an ofiset toe at the free end of the ofiset arm, and a cap, made up of an outer cap member having an aperture near the closed end thereof to receive the odset arm of the cli and an inner cap member adapted to be forced into the outer member to engage the ofi'set arm, an aperture being provided in the closed end of a cap to receive the toe.

p 2. The combined cap and clip above described, made up of a metal clip upon the outside of the cap and extending longitudinally thereof and having an ofi'set arm per endicular thereto carrying an ofl'set toe at t lie free end of the ofiset arm to enter a recess in the closed end of the cap when the arm is passed through the aperture to the and having an ofiset arm an outer cap member, having an aperture.

near the closed end thereof to receive the ofis'et arm of the clip and provided with a f recess in the inner face of the closed end to receive the toe, and provided alsowith screw threads on the inner open end thereof an inner cap engagmg the-interior of theouter cap; all organized, when the inner cap is passed into the outercapto engage the E- set arm and retain the toe in the recess.

aperture near the closed end thereof and provided with a-recess in the inner'face of the closed end and with interior screw threads at the open end thereof; a -clipupon the outside of the cap, extending longitudinally thereofand having a transversely April, 1918,

naeaeeo ofiset arm, carrying a longitudinally extending toe ofi'set at the free end of the arm to enter the recess in the closed end of the cap when the arm is passed through the aperture to the interior of the cap; an inner cap engaging the interior of the outer cap;

a fountain having screw threads adjacent its open end to engage the screw thread within the outer cap, all organized, when the cap is screwed onto the fountain, to force the inner cap toward the closed end of the outer 3. In combination an outer cap having an cap and lock the toe in the recess.

4:. As in claim-1, the inner and outer caps being connected by a split ring seated in op osed grooves.
