7 Claims.

This invention relates to new and useful improvements in the general art of stationery and more particularly to a novel form of pen holder.

The principal object of this invention is to provide a pen holder adapted to hold pen points of various sizes and cross sectional formations.

Another important object of the invention is to provide a pen holder which will not only accom* modate pen points of various size and formation,

10 but which will rmly grip the pen to prevent Wobbling and accidental displacement thereof from the holder.

Still another important object of the invention is to provide a pen holder which will not only rmly grip pen points of various characteristic formations, but which will also permit immediate releasement of the pen point when desired.

These and various other important objects and advantages of the invention will become apparent to the reader of the following speciiication.

In the drawing:-

Figure 1 represents a fragmentary longitudinal sectional view through the pen holder showing a pen point in held position.

Figure 2 is a side elevational view fragmentarily showing the pen holder with the holding means in released position.

Figure 3 is an enlarged end elevational view of the holder.

Figure 4 is a longitudinal sectional View through the sleeve.

Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 denotes the usual shank of the holder which in the present instance is reduced at one end portion to accommodate the ferrule 6 from which projects the pin 1.

'Ihis end portion of the shank 5 is provided with a longitudinally extending opening axially 40 disposed, for receiving the shank portions 8 and 9 of the spring fingers I0 and I I, respectively, as Well as the inner end portion of the elongated core member I2, which core member is preferably of polygonal cross-sectional shape.

As is clearly shown in Figure 1, the outer end portion of the core member I2 is interposed between the fingers IO-II and at its extremity is beveled as at I3.

The finger I0 is provided with the laterally di- 50 verged portion a merging with the inwardly disposed T-formation b.

The outer end of the finger I I is diverged laterally as at c and is provided with the inwardly disposed and transversely extending arcuate- 55 shaped yoke I4.

(Cl. 1Z0-101) As `shown in Figure 1, numeral I5 denotes a standard type of pen point. In properly placing the pen point I5, the blunt end thereof is interposed between the brace extension I6 on the finger I I, and the outer end portion of the core member I2, this portion of the core member I2 preferably being wholly confined within the channel of the pen point.

Now referring to the slidable sleeve ll, it can be seen that this sleeve is provided with a pocketlike construction I8 at its inner end, the forward edge portion of which is disposed and formed to dene a cam surface I9 for riding engagement with vthe pin 1. Obviously when this sleeve I'I is rotated toward the right (see Figure 2) the cam l5 Surface I9 in riding against the pin 7 will cause longitudinal movement of the sleeve in a direction toward and against the fingers Ill-I I. Riding engagement of the sleeve against these fingers Ill-II will cause the fingers to contract, bringing the arcuate-shaped yoke I4 into engagement with the convex side of the pen point and bringing the T-shaped formation b into bridging engagement with the channeled side of the pen point.

It will be observed, that the yoke I4 with the 25 cooperation of the brace formation I6 will firmly clamp the pen point against the core member I2.

At the same time the T-shaped formation reinforces the pen point to prevent any objectionable deformation thereof. 30

The sleeve II may be provided with the usual cork or other suitable covering.

While the foregoing specification sets forth the invention in specific terms, it is to be understood 5 that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention what is claimed 40 iszl. In a pen point holder including a shank, a pair of shank attachable fingers at one end of the shank, and means for contracting said iingers against opposite side portions of a pen point, and a brace formation extending longitudinally of the lingers and adapted to bear against the convex side of a pen point at the shank end thereof.

2. In a pen point holder including a shank, a pair of shank attachable fingers at one end of the shank. and means for contracting said fingers against opposite side portions of a pen point, one of said ngers having a T-head formation bridging the channeled side of a pen point. 55

3. A pen holder comprising a handle part, a core member projecting from one end thereof and adapted to t in the channel of a pen point, a pair of spring fingers connected with said end of the handle and arranged one above the core member and one below said member, said fingers having parts extending toward each other for gripping a pen point between them and for pressing portions of the point against the core member.

4. A pen holder comprising a handle part, a core member projecting from one end thereof and adapted to fit in the channel of a pen point, a pair of spring fingers connected with said end of the handle and arranged one above the core member and one below said member, said fingers having parts extending toward each other for gripping a pen point between them and for pressing portions of the point against the core member, and a sleeve slidably arranged on the handle and engaging the spring fingers for pressing the fingers toward each other when the sleeve is moved outwardly on the handle.

5. A pen holder comprising a handle, a core member projecting from one end thereof, a pair of spring fingers connected with said end of the handle and arranged one above and one below the core member, the upper member having a laterally inwardly extending yoke-shaped part for engaging a portion of the convex side of a pen point, the concave side of which engages the core member and the other spring finger having an inwardly extending extremity having a straight edge for engaging the edges of the pen point and a sleeve slidably arranged on the handle and pressing the spring fingers against the point when the sleeve is moved outwardly.

6. A pen holder comprising a handle, a core member projecting from one end thereof, a pair of spring ngers connected with said end of the handle and arranged one above and one below the core member, the upper member having a laterally inwardly extending yoke-shaped part for engaging a portion of the convex side of a pen point, the concave sid-e of which engages the core member and Ithe other spring finger having an inwardly extending extremity having a straight edge for engaging the edges of the pen point and a sleeve slidably arranged on the handle and pressing the spring fingers against the point when the sleeve is moved outwardly, said sleeve having a'cam part thereon and a pin carried by the handle for engaging the cam part for imparting an outward lsliding movement of the sleeve when the sleeve is partly rotated.

7. A pen holder comprising a handle, a core member projecting from one end thereof, a pair of spring fingers extending from said end ofthe handle, one above and one below the core member, the upper finger having an inwardly extending extremity of yoke-shape for' pressing against a portion of the convex side of the pen pointA and f said finger having an extension intermediate its ends for pressing the inner end of the point against the core member, the extremity of the other finger having an inwardly extendingpart formed with a straightedgevfor bearing against PEARsoN
