ATTACHING CLIP.

Application filed April 15,

My invention relates to an improved attaching means, or clip, for fastening fountain pens and other articles of a similar shape or nature to the sides of pockets or to the edges of garments, and aims to provide a clip having a maximum -of effective gripping surface,

and easily manipulated without damaging the garment.

@ne object of the invention is to e'ect the claspng pressure perpendicular to the thickness of the material engaged, free from wedging or bunching effect thereon, and hence free from forces weakening the hold of thegripping members on the material by tending to push the latter endwise.

A further object is to provide a clipv which may be readily adjusted to engage with equal effect any one of a wide range of thicknesses of material, and which may be readily released from said engagement without the necessity of pulling the material from between the opposed gripping members.

For convenience I show and describe my clip in conjunction with a fountain pen cap, although it is equally applicable to any object of the same general shape which one may desire to attach removably to the cloth of a coat pocket or the like. For example, my improved clip is intended for use with pencils, clinical thermometer cases, spectacle cases and so on, as well as fountain pens.

lllustrative embodiments of my invention are described in the following specification and in the accompanying drawings, wherein Fig. 1 is a longitudinal central section of a fountain pen cap showing one form of my improved clip in connection therewith, showing` the clip in retracted position;

Fig. 2 is a view similar to Fig. 1, but illustrating a modified pivot, the clip being in extended position;

Fig. 31s a view of the inner face of a movfable top of the type shown in Figs. 1 and 2';

Fig. 4 is a perspective view of the upper end and one side of the cap proper without the top, corresponding to Figs. 1 and `2;

Fig. 5 is a perspective view of the clip members; A

Figs. 6 to 11 inclusive are views similar to Fig.. 1, illustrating modified forms of mechanism for moving the clip nger, and

Fig. 12 is a perspective view illustrating features of cap construction'suitable for use with the 4forms of clip shown in Figs. 6 to 11 tu inclusive.

1927. semina. 134,014. l

In the embodiment illustrated in Figs. 1 to 5, inclusive, the clip consists of a finger 1 disposed at right angles to a head 2', said head being slotted as at 3 and provided at the end opposite said finger with an upstandinglug 4, all preferably integral. Said finger may be formed with a re-entrant bend 5, preferably near the free end, for more secure engagement with the material to which the cap is to 'be fastened. The ca used in connection with this embodiment is flirmed with top and side recesses 7 and 8. The head 2 slides in and out in the top recess 7, and the linger 1 may be fully retracted within recess 8, which is suitably hollowed out to take the bend 5, thus avoiding any projections above the side surface of the cap. A top 9 is rotatably attached to the upper end of said cap by suitable pivot means, such as shown at 10, Fig. 1, or 11 Fig. 2, passing through the slot 3 in the head 2.- Said top is spirally grooved, as at 12, in its lower face to engage lug 4 of the head. Thus when the top 9 is turned the travel of the lug 4. in the groove 12 will move the head 2, varying the distance between the 80 linger 1 and the side of the cap. The finger 1 in-all positions will be in the same angular relation to the cap, preferably parallel there-A to, because of the mutual rigidity of the finger 'f and the head 2. e5

In Figs. 6 to 11 inclusive I illustrate forms of my invention wherein the finger is normally held within the side recess of the cap byspring action and is adapted to be moved outwardly by thumb pressure.

ln the form shown by Fig. 6 a single strip of metal is bent as shown, forming a linger 13, similar to the finger 1 of Fig. 1, a cross member or head 14 adapted to slide in a guide-hole 15 in the cap, an axial shank 16, passing through c5 the end of the cap, a button 17, and a llshaped spring 18 the lower end ofwhich rests upon an inner end 19 within the cap. l

Fig. 7 illustrates a modification having the cross member or head 20 in the form of a bow ma spring arranged to be pressed by a stem 21 carrying an-external button 22. The spring cross head 20 is stopped on one end by the barrel of the cap, while the opposite end passes through a guideway 15, and is externally joined to the linger 13.

Pressure on the end button in the modifications illustrated by Figs. 6 and 7 causes the cross head to move outward through the guideway, carrying the finger away from the ma cap in an obvious manner. The guideway forces the close head to move outwardly without tilting, so that the finger is maintained parallel to the side of the cap.

Figs. 8, 9 and 10 illustrate further spring forms, all used in connection with a clip wherein the cross head is straight and transverse to the cap, projecting therethrough on the side opposite to the finger and there ter.- minating in a button 17 The springs 2 3, Fig. 8, and 24, Fig. 10, are of theaccordion type, integral with the clip structure. The spring 25 in Fig. 9 is coiled, bearing at one end against a cross member 26 secured to the clip head and at the other against the inside of the cap.

Fig. 11 shows an' additional modification, of the forms disclosed by Figs. 8, 9 and 10, but having the inner end 27 of the clip head turned upward, inside the cap, engaging one end of the spring 28. This upturned end 27 passes upward through and is adapted to move in a diametral slot 29 in the cap cover 30 and carries an irregularly T-shaped guide member 31 which covers the slot 29 in one direction, projects slight-ly over the side of the `threads 34 stop short of the top of the cap so as to provide a chamber between the outer end of the cap and the end 19 of the plug for the reception of the spring and the clip head. It will be understood that the inner end 19 need not necessarily be constructed and inserted as above described, but for example, may be formed integral with the cap, as illustrated at '37 Bin Figs. 7, 9, lO'and 11, or constructed in any suitable manner.

A preferred cap end construction for use in conjunction Awith any of my above described spring-actuated clips, is shown in Fig. 12, wherein a reduced externally threaded end 38 of the cap barreltakes an internally threaded cover, such as 39, Fig.,10. The reduced end is slotted, as at L10-41,.for the reception of the clip head,- which is held in-place by the cover 39. The side of the barrel is recessed as at 4.2, forming a seat for the linger 13. It is intended that Fig. 12 be considered as in the nature of a diagrammatic showing, and that certain features thereof yare to be understood as subject to appropriate modification to suit various forms of spring, as particularly illustrated in Figs. 6 to 11 inclusive. Thus a cap for use with the spring shown by Figs. 6, 7 and 11 will be provided only with the slot 40 while the depth of the threaded end 38 will be less in connection with such springs as are illustrated by Figs. 9 and 10 than with those shown in Figs. 6, 7, 8 and 11.

To slip the pen into engagement over the edge of a pocket or the like, the finger is moved far enough out to admitthe cloth loosely between the finger Iandthe side of the cap without wear on the cloth. The cloth is then tightly gripped by retraction of the finger. rlhe engagement is released in the reverse order, and the finger afterwards retracted into its recess, whereupon the cap presents an exterior surface free from projections.

The feature of having the finger always parallel to the side of the cap gives a very secure hold by reason of the fact that the inner surface of the finger and the entire opposed surface of the side of the cap bear with substantially equal .force upon the cloth gripped between them. Further security particularly in gripping thin materials, results from the binding effect between the reentrant bend 5 and its corresponding hollow. As distinguished from this parallel and even grip, the usual type of clip, which is either rigidly or pivotally secured .to the cap, holds the cloth by a wedging action which includes a force component tending to slide the cloth out of the wedge. With thin cloth this` results in a hold only close to the apex ofthe wedge, while with a thick cloth, such as overcoating, the clip finger is sprung out so far thatl the sliding component is pronounced. As a result it is almost impossible, practically, to fasten a fountain pen having the usual type of clip securely to such thin material as that of a silk shirt or to such thick material as that of an overcoat, particularly if the pen be placed at an angle on an edge of the garment instead of hooked over the top of a pocket. j

It is to be understood that I do not limit ymyself to the preferred forms of my invention which I have described and illustrated, but what I claim is:
