CLIP FOR MECHANICAL PENCILS, FOUNTAIN PENS, AND THE LIKE Fred D. Woods. (illencoe, 111.. asslgnor to Autoihlintisompany, Chicago, 111., a corporation of Application July 13, 1944, Serial No. 544,719

I 4 Claims.

This invention relates to a clip for mechanical pencils, fountain pens and the like, and more particularly to means for mounting the clip on the article to which it is to be applied.

Among the objects of the present invention is to provide novel means for mounting a clip onto an article such as a mechanical pencil. fountain pen or other more or less similar article, in such manner that the clip may be quickly and easily applied to the article in a secure manner and to conceal from view the ends of the fulcrum pin on which the clip is pivotally mounted.

A further object is to so mount a clip onto an article of the 'class described, that thearticle will have a neat, stream-lined exterior appearance, and the clip will be efficient and positive in operation.

A still further object is to provide a mounting, of the kind referred to, specially arranged to readily and effectively accommodate a spring for normally urging the clip to closed position.

Another object is to provide a novel arrangement of spring and spring support for yieldably urging the free end or bulbous tip of the clip against the exterior surface of the article.

Other objects, advantages and capabilities, inherently possessed by the present invention, will later more fully appear.

My invention further resides in the combination, construction and arrangement of parts il-'10 lustrated in the accompanying drawing, and while I have shown therein preferred embodiments, I-wish it understood that the same is susceptible of modification and change without departing from the spirit of my invention.

' In the drawings:

Fig. 1 is an enlarged fragmentary side elevation of a portion of a mechanical pencil, fountain pen or the like, having a clip applied thereto by a mounting embodying my invention,

Fig. 2 is an enlarged fragmentary longitudinal section taken through an axial plane, some parts being shown in elevation, of the end portion of the article and showing the clip applied thereto by the mounting of the present invention.

Fig. 3 is an end view of Fig. l but rotated through a ninety degree angle.

Fig. 4 is an enlarged longitudinal sectional deof my improved fulcrum yoke tail of one form member.

Fig. 5 is an end view of Fig. 4. Fig. 6 is a longitudinal section on the line Gi of Fig. 4' locking in the direction of the arrows. I Fig. 7 is an enlarged perspective view of a modified form of fulcrum yoke member.

Fig. 8 is an enlarged fragmentary longitudinal section of a portion of the fulcrum yoke member of Fig. '7, showing how the same is applied to the article.

Referring more in detail to the drawing the clip I is rotatably mounted by a novel mounting in the rear end of the body of a mechanical pencil, fountain pen or the like 2, hereinafter referred to as the article, and the free end of the clip constantly urged toward the article, sothat when the article is attached to a pocket or other support, the material of the pocket or the like will be gripped between the clip and the article, but the article may be removed therefrom by a longitudinal pull or it may be applied thereto by a longitudinal push, at which time the curved surface of the bulbous tip 3 will ride smoothly over the material.

As seen in Figs. 1-3 the rear end 2 of the article is provided with a longitudinal slot 4 of a size to have freely and 'movably seated therein the arcuate part or rear end 5 of the clip, which arcuate part or rear end is preferably hollow with walls of the thickness of the metal or other flat material from which the clip is folded or bent into shape, as shown by the dotted lines 8 and I in Figs. 2 and 3. The shape of the clip and its arcuate part or rear end mounted in the slot s shown in side elevation in Fig. 2.

One form of the mounting or fulcrum yoke member a for mounting the clip in the article is shown in Figs. 4-6, and comprises a part 9 having a pair of laterally spaced apart parallel yoke arms In and l I and a threaded stem l2 adapted to threadably receive a nut l3 to secure this mounting or fulcrum yoke member 8 in the article as will be understood in Fig. 2. The mounting or fulcrum yoke member ispreferably formed of a cylindrical shape, although other cross-sectional shapes may be used as desired. The rear end 2 of the article is provided with oppositely positioned grooves c and d formed as a segment and opening into the slot 4 to conformably receive the outer faces of the yoke arms l0 and I I (see Fig. 3), the slot 4 being extended at e for a purpose to be later more fully explained.

The yoke head I! is formed at its lower end with an angular slot IS, the top side I 6 (as viewed in Fig. 4) of which is formed at such angle as to effectively receive and seat the short end ll of the spring l8 which when assembled is curved as shown in Fig. 2 and its longer end is secured between the spaced flanges 20 at the extended end or tail piece 29 of the arcuate rear end -5 of the clip memberby crimping these flanges inwardly through the yoke arms and H, so that when the rear end or arcuate part of the clip, the fulcrum yoke member and the fulcrum pin are assembled together in the slot 4, the fulcrum pin will not fall out of place and its ends will be concealed from sight. Also the outer ends of the yoke arms are of such shape as to conform to the outer adjacent end surface of the article to give a pleasing appearance and be free of undesirable projections.

The rear end 2 of the article at the end of the slot is formed with a counter bore or recess 26 to receive the yoke head I4, and coaxial with counter bore 26 is a hole 21 to receive the stem l2. This provides a partition or annular flange 28 (other shapes than round for the yoke and stem may be used if desired) against the inner face of which the nut l3 Or other fastening means may be tightened to securely hold the mounting means and clip in position.

When assembling the clip I, fulcrum yoke member 8 and the spring l8 before insertion into the slot 4, the spring l8, which may be a round wire, or flat strip, or partially curved depending upon its strength, is positioned with its short end in the angular slot l5 and above the fulcrum pin openings 2| and 22. It is then bent under tension and pushed into the hollow of the rear end or arcuate part 5 of the clip with the arms l0 and II straddling said rear end until the fulcrum pin openings 2|, 22, 24 and 25 come into alinement, whereupon the fulcrum pin 23 is then forced into the alined openings. The flanges 20 may then be crimped inwardly against the long end IQ of the spring, or they may be left uncrimped, if desired, because the arrangement of parts is such that the spring will remain in position without such crimping. As will be understood the tension of I the spring when in its final position will be such as to urge the bulbous tip 3 of the clip against the outer face of the article.

As seen in Fig. 2, the slot 4 is extended forwardly at its lower end at e to movably receive the extended end or tail piece 29 of the tail of the clip, which may move inwardly into space f when rotated. The arcuate part or rear end 5 of the clip and extended end or tail piece 29 are freely movable in the slot to enable the necessary limited rotational movement of the clip with relation to the article. The nut l3 may be tightened in the position shown in Fig. 2 by an elongated socket wrench inserted into the hollow of the article, or otherwise as desired.

In the modification shown in Figs. 7 and 8 the structure and arrangement of parts is the same as that of the preceding views except that instead of the threaded stem [2 I have formed the inner end of the fulcrum yoke member with a tubular projection 30 which is inserted through the hole 21 and its extended inner end crimped over by a properly shaped crimping tool to form the annular (or other shape) flange 3| to securely hold the fulcrum yoke member in place.

Having thus described my invention, I claim:
