3 Claims.

My invention relates to writing implements, such as pencils and pens and particularly to a novel body or barrel and clip and its means of attachment to the barrel.

A pencil or pen that is circular in cross section throughout the major portion of its body or barrel is desirable for several reasons, but such contour or cross sectional shape does not adapt itself for cooperation therewith of a clip of the most desirable form, that is, a clip such as shown in the patent to Keeran, No. 1,625,809 of April 26, 1907; this for the reason that such a clip requires at least three parallel, angularly disposed plane surfaces for cooperation with the head of the clip. Further, inasmuch as such clips are held by means of a single screw or fastening device, it is desirable that the body of material for engagement of the screw be thicker than would otherwise be required for a pencil of the ideal weight and diameter. It will be understood that inasmuch as the clip is applied to the upper end of the pencil body at the point where a relatively large axial chamber is provided for reserve leads, the surrounding wall is relatively thin and does not give adequate support for the clipattaching screw, without increasing the diameter of the pencil beyond what would otherwise be necessary.

I accomplish all the advantageous results above indicated, by providing a pencil or pen having a body or barrel of circular cross section, adding material to one side thereof at one point near the upper end, and shaping said thickened area to provide at least three parallel angularly disposed planes. In that manner the clip may be attached thereto by the use of a single screw. Thus, I am able to provide an ideal clip attachment construction, a barrel or body of circular, as distinguished from polygonal cross section, and accomplish a substantial saving in the quantity of material used in the barrel.

Another feature of construction relates to the shaping of the clip head in such manner that a firm and secure engagement is effected between the clip and faceted portion of the barrel.

The invention will be more readily understood by reference to the accompanying drawing in which,

Fig. 1 is a plan view of a pencil constructed in accordance with my invention;

Fig. 2 is a side view thereof; and,

Figs. 3 and 4 are sectional views on the line 4-4 of Fig. 2, Fig. 3 showing the shape of the clip head prior to assembly, as shown in Fig. 4.

In the accompanying description and claims, where ever reference is made to a pencil, it is to be understood that a pen is contemplated as the equivalent thereof and that in the case of a pen,

the clip is applied to the cap instead of to the barrel.

In the drawing I have shown a pencil having a hollow body ID, of circular cross section, one portion H of the wall, at or near the upper end of the body, being slightly thickened and shaped to provide facets or angularly disposed, longitudinally extending faces l2, l3, l4, preferably in the form of planes that merge into the circular surfaces of the body at the two ends of the faceted portion. That is to say, a body of material is added to the peripheral surface of the cylindrical hollow body, as indicated by the dotted lines in Figs. 3 and 4 and this serves to provide for three angularly disposed plane surfaces adapted to be engaged by the head l5 and side wings l6-ll of a clip. The clip is preferably shaped as shown in Fig. 3, that is, with the wings formed at a less angle than they will assume when assembled with the body, the wings being flared as the clip is forced into position by the seating of the screw i8. As the clip will be composed of somewhat resilient material, this insures a firm and accurate fitting of the clip. As additional material is provided to accommodate a single somewhat longer screw than heretofore used, a much stronger construction is assured without the use of unnecessary material.

It will be understood that I contemplate the construction of the pencil body of a moldable material such as bakelite, although the idea here disclosed is equally useful in connection with other materials.

I claim:

1. In combination, a writing implement having a body substantially circular in cross section, a portion of the body being extended beyond the contour of the remainder of the body and shaped to provide facets, a clip having a head provided with side wings adapted to fit said facets, and a single screw engaging the extended portion of the body and adapted to hold the clip in place.

2. In combination, a pencil body circular in cross section, a portion of the body near the upper end being extended beyond the circular contour of the remainder of the body and provided with at least three angularly disposed faces, a clip having a head provided with side wings, and fastening means for securing the clip head on said extended angular portion of the body.

3. In combination, a pencil having a round body and a laterally extended portion at one end, said extended portion having at least three angularly disposed longitudinally extending faces, a clip shaped to provide three angularly disposed portions adapted to fit said faces, and a screw engaging the body for holding the clip in place.
