ATTACHMENT FOR FOUNTAIN PENS.

Application filed November 16, 1926. Serial No. 148,718.

This invention relates generally to improvements in fountain pen attachments, but more particularly to the. protecting caps thereof.

One of its objects is to provide the cap with an adjustable fastening clip or clasp for retaining the pen in pockets of Varying depths.

Another object of the invention is the provision of a cap for fountainpens and the like having a combined pocket-engaging clasp and implement, such as a. knife, letter larged vertical section on line 33, Fig. 2. v

Figure 4 is an enlarged horizontal section on line H, Fig. 1. Figure 5 is a detached perspective View of the combined clasp and implement. Figure 6 is a vertical section of a modified form of the invention. Figure 7 is a view similar to Figure 6 showing the cap fitted with the plug shown in Figure 3.

Similar characters of reference indicate corresponding parts throughout the several views.

The invention is shown, by way of example, in connection with a fountain pen of ordinary construction, 10 indicating thebody or pen-holding element and 11 the usual cap removably applied to the body for normally .covering and protecting the pen-point.

Mounted on the, cap for movement lengthwise thereof to assume any one of a plurality of set positions is a spring clip or clasp 12 which functions to retain the pen in ones pocket. At its lower end, the clasp may be provided with a ball 13 or similar gripping member, while its upper end terminates in a guide member preferably in the form of a laterally ofi'set bar or shank 14 engaging registering longitudinal slots 15 and16arranged, respectively, in the side wan of the cap 11 and in a plug or bushing 17 fitted in the interior of said cap, as shown in Fig.

The inner end of this guide bar is provided with an anchoring lip or head 18 which engages a longitudinal passage or opening 19 disposed substantially centrally of the bush ing and intersecting the slot 16 thereof. The slots 15 and 16 together with the opening 19 constitute a single passage, T-shaped in crosssection, and the corresponding portions 14 and 18. of the clasp are correspondingly shaped to have a sliding fit therewith. By this construction and arrangement of parts, the clasp maybe readily shifted lengthwise of the cap 11 While displacement laterally thereof is prevented.

In order to lock the clasp '12 in any set position on the pen-cap, the same carries a releasable catch, of any suitable construction, arranged-to interlock with the cap in any suitable manner. The catch shown in the drawings, by way of example, consists of a bail-like member 20 fulcrumed at 21 to the clasp and carrying studs 22 adapted to engage one or another of a series of recesses or openings 23 formed in the o posing wall of the cap on opposite sides of its slot 15, as shown in Figs. 2 and 4. I

Aside from its function as a means for retaining the pen in ones pocket, the clasp may also constitute a carrier for an implement 24, such as a knife, letter opener or the like. This implement is preferably formed integral with the clasp-head 18 and is likewise guided and'normally contained in the bushing passage 19. \Vhen it is desired to project the implement from the cap for use, the locking catch 20 of the clasp is released and the latter shifted toward the top of the cap to the position shown by dotted lines in Fig. 3, after which said catch is allowed to' engage a corresponding pair of the openings 23 to lock the clasp and its implement in a set position. Similarly, when the clasp is slid downwardly on its cap, the implement is drawn into its passage 19 in the bushing 17 where it is concealed and out of the way.

As shown in Fig. 3, the upper end ofthe bushing 17 extends beyond the correspond-.

ing end of the cap 11 and has an external screw'thread 25 for receiving a cover or closure 26 which may be rigidly held in place after assembling the parts by a screw 27 or otherwise. The top of this cover has an opening 28 in line with the bushing-opening 19 for permitting the passage of the implement 24 therethrough. In the initial assembling of the parts, the cover 26 is re 'moved and the guide bar 14 and implement 24 of the clasp are slid downwardly through the open upper ends of the slots 15, 16 and opening 19, after which said cover is applied.

It will be notedthat in the lowest concealed portion of the implement 24, its upper or pointed end is an appreciable distance below the top of the cap 11 so as to allow for a predetermined range of adjustment of the clasp lengthwise of the cap without exposing the pointed end of the implement. In the position of the parts shown by full lines in Figs. 1, 2 and 3, the clasp is set for the ordinary sized pocket. For pockets of more thanordinary depth, the clasp may be accordingly shifted upwardly on the cap and thereby permit the major portion of the pen to be lodged within the pocket with only a small portion thereof exposed above the pocket-opening.

In the modification of the invention shown in Fig. 6, the clasp 29 has a guide bar 30 of circular cross section and its implement 31 is in the form of a cutting disk. By this construction, it is possibleto turn the clasp to the position shown by dotted lines in this Figure, where it is out of the way and not liable to interfere with the hand of the user while writing, the catch 32 serving to hold it in such position.

I claim as my invention 1. An attachment for pens, comprising a cap having a longitudinal row of recesses therein, a pocket-engaging clasp applied thereto and adjustable lengthwise thereof, and a locking catch mounted on said clasp for engaging one or another of said recesses.

2. An attachment for pens, comprising a cap, a pocket-engaging clasp mounted on said cap for movement lengthwise thereof, and an implement carried by said clasp and normally housed within said cap, said implement being projectable from the cap by movement of said clasp.

3. An attachment for pens, comprising a cap, an adjustable pocket-engaging clasp mounted on said cap for movement lengthwise thereof, an implement carried by said clasp and adapted to be projected from and retracted into said cap by the movement of the clasp, and means for releasably locking said clasp and its implement in a set position.

4:. An attachment for pens, comprising a cap, a combined pocket-engaging clasp and implement applied to said cap and movable lengthwise thereof to a plurality of different positions, the implement being located within and disposed below the top of the cap in one position and exposed above the cap-top in the other position, and means for holding the parts in such positions.

the clasp being arranged exterior of the cap and the implement being normally housed therein, and means for holding said parts in a set position. 1

7. An attachment for pens, comprising a cap having a longitudinal slot therein, and

a member arranged to traverse said slot,

the outer end of said member terminating in a pocket-engaging clasp extending in one direction therefrom alongside the outer wall of the cap and the inner end of said member terminating in an implement extending in the opposite direction and normally housed within said cap.

8. An attachment for pens, comprising a cap having a longitudinal slot therein, a guide member arranged to traverse said slot, the outer end of said member terminating in a pocket-engaging clasp extending in one direction therefrom alongside the outer wall of the cap and the inner end of said member terminating in an implement extending in the opposite direction and normally housed within said cap, said implement being movable into and out of the cap in response to longitudinal movements of the guide memher, and means for releasably holding said member and the parts carried thereby in a set position.

9, An attachment for pens, comprising a cap having a longitudinal slot therein, a

plug fitted in the cap and having a slot registering with the cap-slot and a longitudi nal passage intersecting the plug-slot, a guide member arranged to traverse said registering slots, a pocket-engaging clasp disposed at one end of said member on the exterior of the cap, an implement disposed at the opposite end of said member and normally housed in said plug-passage, said implement being movable out of the passage for use, and means for releasably locking said member and its parts in ditlerentpositions.

,10. An attachment for pens, comprising a cap, a pocket-engaging clasp rotatably mounted on said cap to assume either a downwardly or upwardly facing position, position, and means for holding said clasp in either of such positions.
