9. Claims. 1

The present invention relates to a clip for mechanical pencils, fountain 'pensand the like, and especially to a novel clip assembly or construction and in the novel means and manner of mounting the clip.

Among the objects of the present invention is to provide a novel clip assembly adapted to be mounted in suchmanner upon the upper end of the cap of a mechanical pencil, fountain pen and the like, as to eliminate any objectionable features of prior constructions where theupper end of the clip is pivotally mounted in the end ofthe cap.

Another object of the invention is the provision of a novel yoke or mounting for the clip and a novel means for exerting spring tension on the clip.

A further object of thepresent invention is the provision of a novel clip and cap assembly in which the clip islimited in the amount it can be raised or pulled away from the cap. This novel construction and arrangement eliminates all undue or unnecessary strain upon the tension means which tends to return the clip to its position adjacent the'cap.

. Further objects are to provide a construction of maximum simplicity, efiiciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the construction,combination and arrangement of parts illustrated in the accompanying drawings, and while there is shown therein a preferred embodiment, itis tobe understood that the same is susceptible of modification and change, and comprehends other details, arrangements of parts, features and constructions without departing from the spirit of theinvention.

In the drawing:

Figure 1 is a view in side elevation of a cap for a mechanical pencil, fountain pen and the like, to which the novel clip has been applied.

Figure 2 is a View in vertical cross section taken in a longitudinal plane through the cap and clip mounting on the line 2-.2 of Fig. l, the clip and tension means being shown in side elevation.

Figure 3 is a view in side elevation ofthe clip.

Figure 4is a view in vertical cross section taken in a plane represented by the line 4-4 of Figure 3 and viewed in the direction of the arrows.

Figure 5 isaview in elevation of theyoke upon which-the clip is fulcrumed.

Figure- 6 is a view in perspective of the'n'ovel spring or tension means.

Figure 7 is" a fragmentary view in perspective of the upper end of the clip.

Referring more particularly to the illustrative embodiment shown in the drawings, the clip I is disclosed as fulcrumed or pivotally mounted in the upper end of a cap or hollow body 2 for a mechanical pencil, fountain pen or similar article adapted to be carried in the pocket or attached to a part of the clothing or other support. To permit such ready attachment tothe pocket part of the clothing or other support and at the same time prevent accidental or unintentional removal; the clip is so constructed, arranged and designed as to yieldingly grip the material-of the pocket or other support with sufficien't tension to prevent such unintentional detachment;

In the presentnovel construction the upper, enlarged end 3 of the clip is shown as pivotally mounted with a slot 4 in a yoke 5 and upon a fulcrum pin 6 adapted to be received within the aligned openings 1 in the yoke, and with its outer surface substantially conforming to the end of the cap. The shank 8 of the clip extendsalongsideof or substantially parallel to the cap 2 and'is provided at its lower end with a curved rise or rounded portion 9.

The yoke 5 is formed as a substantially tubular member slotted at 4 through one side and for a considerable portion of its length for the reception of the enlarged end 3 of the clip and to permit this end to fulcrum or pivot about the pin 6''. As this-slot 4 does not extend through the upper end of the yoke 5,,it thereby materially strengthens this end and prevents any binding effect between the clip and the opposite sides of the yoke. The reduced end H! of this yoke is provided with a tubular opening Ill and is exteriorly threaded at H for threaded engagement by a nut or the like l2, While the upper end is enlarged at 13 and so contoured as to form a closure with and conform with the contour of the upper end 2 of the cap 2. The cap may be of metal or other suitable material and is provided with a sleeve providing a spacing bushing or liner 14 for removably and centrally'attaching the cap to the body of the pencil or pen. This liner may be of plastic or other suitable reinforcing material and is shown as provided with ashoulder or offset l5 intermediate its length suitably arranged for association with the end of a mechanical pencil or fountain pen, a shoulder or offset "5- against which the nut; I2 is adapted to seat, and a shoulder or offset l'l limiting the longitudinal adjustment of the yoke by providing a stop against which the shoulder or stepped portion I8 of the yoke is adapted to engage.

The enlarged end 3 of the clip is provided with a rear face or edge Iii forming a stop or safety feature to prevent the curved rise 9 of the clip from being raised orwithdrawn more than a'predetermined amount away from the cap or barrel. For example, we find that by so contouring the rear face or edge IQ of the end 3 that it contacts the inner surface or wall of the yoke at 29 when the curved rise has been raised or withdrawn approximately one-eighth A) in ch;from the cap, all unnecessary strain is removed from the tensioning means and thus greatly prolonging-its life.

The tensioning means is shown as comprising a leaf spring or spring wire 2 [$0 contoured as to 4 jacent the notch, a fulcrum pin in the aligned openings in the yoke and the opening in the clip for pivotally mounting the enlarged end of the clip within the slot in the yoke, and tension means received within the hollow yoke for urging the other end of the clip against the article and provided with an end loosely received within the notch.

2. A clip assembly for the caprof a pencil,

pen and the like, comprising a hollow tubular yoke mounted in the end of the cap, said yoke and cap having aligned slots inone side only and, extending longitudinally to the end thereof,

port and an enlarged part at the other end provide an upwardly projecting and slightly bent end 22 and with its other end 23 bent or deformed to; provide a substantially U-shaped part conformably received within the reduced end of'the yoke 5, as shown in Figure 2. This tensioning means is mounted in the end 3 of the clip by 10- cating the free end 22 thereof in a slot or notch 24, The U-shaped part 23 is provided with a short bend or projection 25 resting against the end 26 of the slot 4, and which bend or projection restricts the downward movement of the spring within the tubular opening in the yoke. The active end 22 of the spring loosely seats within the slot or notch 24 and prevents any substantial upward or longitudinal movement of the spring within the yoke due to the limited depth of this slot. the reception of the pin 6.

- In the assembly of the'clip unit including the yoke, clip and spring, the U-shaped end 23 of the spring is first guided or entered into the tubular opening in the yoke for approximatelyonehalf its length in order that the opposite end 22 of the spring is spaced sufiiciently from the surface or rear wall 20 to permit the enlarged end 3 of the clip and the notch or slot 24 therein to .slip freely over the end 22 of the spring, whereupon the clip may be pushed into place in the yoke. The fulcrum pin 6 is then inserted into the aligned openings '1 in the yoke and the opening 2'! .in the clip and the clip unit is ready for insertion ;into the upper end of the cap 2 and liner i4.

.Next the nut I2 is threaded onto the threaded end H of the yoke and the parts are locked in assembly. Any suitable tool or the like may be provided for insertion into the hollow end of the cap -2 or other article upon which the clip is to be mounted, for securing the nut upon the yoke.

ltween the parts.
