. 8 Claims. (01420-9) This invention relates to pencil holders, and the primary object is to provide a novel, efiective and uniquely constructed grip for pencils, wherein is provided a specially formed tubular body, and

a compressible sleeve which telescopingly engages the body and co-operates therewith in removably supporting a pencil and precluding displacement inwardly of the same during its use.

One of the salient aims of the instant invention is the contemplation of a pencil'holder having a coacting, tubular body and a sleeve, both of which are formed in a special manner to present an effective pencil grip,'said parts being more securely drawn'together toward a gripping position as relative longitudinal movement between tubular body and sleeve takes place.

A yet further object of the instant invention is to provide a pencil holder having a tubular body, wherein is formed a plurality of flutes that coact with one or more annular, inwardly pressed grooves formed in the wall of the, split pencilcarrying sleeve.

The specific structural details forming some of the objects of this invention'are exceptionally important and the same will appear duringthe course of the following specification, referring to the accompanying drawing, wherein:

Figure 1' is a side elevation of .a pencil holder embodying this invention and having a pencil associated therewith.

Fig. 2 is an enlarged, central,longitudinal section through a portion of the length of the pencil holder, with the pencil in position. I Fig. 3 is a vertical cross section, taken on line III-4110f Fig. 2. j Fig. 4 is a side elevation of the longitudinally split sleeve forming a part of this pencil holder, showing the same entirely removed from the other parts.

Fig. 5 is a fragmentary, side elevation of the tubular body showing the series of flutes formed inthe annular wall thereof.

Fig. 6 is a'fragmentary, broken-away, side elevation of a tubular body for holders of the character contemplated, but showing a modified form of the same, and,

Fig. 7 is another modified form of the same element.

A holder made'in accordance with this invention is particularly useful in carrying the well known pencil 10. These pencils vary in diameterv to an extent where holders must be made with.

gripping elements that will be effectivewhen any size pencil, having a diameter falling within the proached.

limit of tolerance permitted, is associated therewith. This unique holder will allow the use of pencils varying several thousandths of an inch in diameter, and the means whereby the pencil is effectively gripped includes two major elements, one a tubular body 12 and the other a split pencilcarrying sleeve 14. In forming thetubular body 12, the same is preferably made of relatively thin material and provided with inwardly directed shoulders or portions having a distance therebetween substantially less than the inside diameter of body 12 and slightly less than the minimum diameter of sleeve 14. when it is completely compressed against pencil 10.

The preferred form of creating such holders is the pressing into body 12 of a plurality of flutes 16, each extending longitudinally along body 12 and arranged in a circumscribing figure, such as shown in Fig. 3. These flutes are further formed so that the end thereof farthest removed from the adjacent end of bodyv 12 is deeper than the opposite end. Specifically, the depth of each flute 16 progressively increases as'th'e innermost end is apr After flutes 16 have been formed in body 12, a cover 18 is moved'to position around body 12 and, inmost instances between embossments20 so that flutes 16 are concealed from view and no bulging nor displacement on the part of body 12 35 7 takes place whenpencil 10 is moved into position.

Split sleeve 14 is shown in detail in Fig. 4 and the same slidably engages pencil 10, and in view, of the longitudinal split which creates spaced-apart edges 22, this sleeve may slide longitudinally along 0 pencil 10 upon the application of a slight amount of force. A series 'of annular, inwardly pressed grooves forming in ernal embossments 24 is formed in the sleeve 14 and the portion of sleeve 14 intermediate these embossments 24 is outward- 1y arched, as clearly shown in Fig. 4. This arching normally takes place when embossments 24 are formed in split sleeve 14.

As shown in Fig. 2, when sleeve 14 is positioned and moved into telescopin engagement with tubular body 12, sleeve 14 is forced tightly against pencil 10 by movement against the inner inclined faces of the series of flutings 16. As pencil l0 and its associated sleeve 14 is moved longitudinally into body 12, the grip becomes tighter and internal embossments '24 bite into pencil 10 to form slight annular indentations 26, as shown in Fig.

2. The distance between opposed flutes 16 is less than the minimum diameter possible to be created by compressing sleeve 14 and, therefore, further the tubular body,

longitudinal inward movement on the part of sleeve 14 will be precluded.

Since sleeve 14 grips pencil 10 as heretofore stated, it is obvious that further movement on behalf of that element is likewise estopped. When pencil l0 and sleeve l l is moved into the position shown in Fig. 2, a tight frictional connection is set up between all the parts of the assembly and the pencil may be used without danger of its collapsing. In spite of this fact, an outward pull on the extended end of sleeve 14 will immediately withdraw both sleeve and pencil 10 either for purpose of arranging the entire parts of the pencil for drawing pencil 10 outwardly to expose more of its length as sharpening takes place.

In Fig. 6 the same principal of forming a tubular body is illustrated, but in lieu of flute 16, a continuous, annular shoulder is formed in housing 52, against which split sleeve 14 is moved when the parts are assembled.

The same ideals likewise involved in the tubular body illustrated in Fig. 7, which is a further modification over those types shown in the previous figures. In this'instance tubular body 69 has an internal einboss 62 to press the shoulder or opposed part, against which split-sleeve 14 is pressed t'o-tigh tlygrip sleeve 14.

It is understood that many slight modifications in the construction of a pencil embodying this invention might be made without departing from the spirit thereof or the scope of the appended claims.
