4 Claims.

This invention relates generally to writing utensils and more particularly to novel structure for combining a mechanical or an automatic pencil with a ball point fountain pen and a cap having a pencil eraser associated therewith.

Another object of this invention is to provide a novel cover or cap for the fountain pen portion of the combined writing utensil having a removable, or replaceable, eraser carried by a reversible holder at the outer end of the cap, and in which the cap is so constructed as to limit the movement of the eraser into the cap and also to resiliently hold the eraser in position on the cap.

Still another object of the invention is to provide a supporting clip for the cap or closure of the ball point pen, in which the clip is so constructed as to prevent inadvertent disengagement of the eraser from the cap on which it is removably disposed.

With these objects, and others which will appear as the description proceeds, in view, my invention resides in the combination and arrangement of parts, and the details of construction, set forth. in the description and illustrated in the drawing and then more particularly defined in the appended claims.

Figure 12 is a top view of the clip illustrated in Figure 11.

Referring to the drawing, and initially to Figures 1, 2, 11, and 12 thereof, I have disclosed an embodiment of a combined pen and pencil constructed according to this invention. The combined pen and pencil, generally indicated by the numeral I0, includes generally a mechanical pencil II connected in end to end relationship to a fountain pen I2 of the ball point type.

The mechanical pencil section II of the device includes a tapered elongated hollow cylindrical body l3 open at the opposite ends thereof. A pencil lead advancing and retracting mechanism I4 is disposed within the hollow body I3, andextends outwardly through the smaller end thereof. The lead advancing and retracting mechanism l4 includes a tapered, or conical, end piece I5, which is faired into the smaller end of the tapered body I3. The larger end of the body I3 is internally threaded as at I6, and is also provided with a reduced diameter annular shoulder H. A cylindrical member I8 tightly engages within the hollow body I3 and is closed at one end as at I9. As seen in Figure 1, the cylindrical member I8 opens towards the larger end of the body I3.

The fountain pen section I2 of the combined pen and pencil I0 includes a tapered elongated body 20 having a reduced diameter threaded portion 2I extending from the larger end thereof. The larger end of the tapered body 253 has a diameter equal to the diameter of the seat I'I formed at the larger end of the body I3, and the reduced diameter threaded portion 2| engages the internal threads I5 of the body I3 for securing the pencil section to the pen section of the device. An elongated tubular reservoir 22 extends from the reduced diameter portion 2! of the fountain pen body 20, and projects into the cylindrical member I8. The tubular reservoir 22 is formed with radially extending openings 23 adjacent the end thereof. A passageway 2 4 extends through the wall of the body I3 and the cylindrical member l8 for venting the tubular reservoir 22 to the atmosphere. A ball point of conventional design 25 extends from the reduced diameter end of the body 28 of the pen section.

A cap member, generally indicated by the numeral 26, is provided for enclosing the ball point fountain pen I2, when the latter is not in use. The cap 26 includes an elongated tapered hollow open ended body 2?. The large end of the body 2'? is dimensioned for frictional engagement over the large end of the body 29 and onto the seat 11 at the large end of the body I3. This frictional engagement maintains the cap 26 in position covering the pen section I2 of the device. A supporting clip 23 is mounted upon the body 2? of the cap, and includes a resilient arm 28, extending parallel to the longitudinal axis of the body 21, and an annular portion 30 formed integral with one end of the arm and engaging over the smaller end of the tapered body 21, The inner edge of the annular portion 39 is crimped as at 3I for securing the annular portion, and therefore the supporting clip 28 to the cap. As seen in Figure l, crimping of the edge of the annular portion 30 as at'3lforms an inwardly directed annular rim or shoulder 32 on the inner surface of the body 21 adjacent the smaller end of the latter. An erasing element 33, including a cylindrical holder 3d, and an abrading element 35 extending therefrom, is mounted within the smaller end of the body 21. As seeninFigure l, the annular rim 32 engages the edge of the holder 34, and thereby limits the movement of the erasing element 33 into the body 21. The holder 34. of the erasing element is indented at 33 for retaining the abrading element 35 within the holder.

In Figures 3 and 4 I have illustrated a modification of the cylindrical member I? mounted within the body is of the pen section 5!. The cylindrical member its, closed at one end by the end wall 19a, is formed with circumferentially spaced apart longitudinally extending inwardly ofiset channels 33, which open towards the large end of the body 23a. As shown in Figure 4, a plurality of additional Writing lead 38 may be stored in each of the channels 31, and are accessible when the body 29a of the pen section is removed from the body iZa of the pencil section.

In Figures 5, 6, and 8, I have illustrated a modification of the cap 23b, in which the body 2??) is formed with the annular inwardly directed rib 32?) adjacent the smaller end of the body. In this modification, semi-circular resilient tabs 39 are struck inwardly from the body .Z'ib, between the annular groove forming an internal rib 32b and the adjacent end of the body. The resilient tab 39 engages against the side of the holder 34b of the erasing element 331) for retaining the erasing element in its position in the smaller end of the body Ell). In Figure 5, the erasing element is shown in an inverted position, with the abrading member 3% extending into the body 2112, in a position of non-use. In Figure 6, the erasing element has been disposed in the body 211) in operative position, with the abrading element 35?) extending outwardly of the small end of the body 2%.

In Figure '2, I have illustrated a modification 330 of the erasing element. In this modification, the cylindrical holder t le is provided with longitudinally extending circumferentially spaced apart outwardly struck resilient ribs ill. The ribs 40 resiliently engage the inner surface of the smaller end of the body of the cap. The resilient engagement of the ribs ill with the cap, not shown, will retain the erasing element 330 in its selected position on the smaller end of the cap.

In Figure 9, I have disclosed a further modification EBd of the cylindrical member fitted within the body 13 for receiving the reservoir 22 of the fountain pen. The cylindrical member lSd is open at each of its opposite ends, and a cupshaped member ii is provided for closing the end of the cylindrical membe normally closed by the end wall is, as shown in Figure 1. The cupshaped member i! is formed with a diameter substantially equal to that of the cylindrical member Hid, and is formed with the spaced apart slots 42 opening through the edge 43 thereof. The slots 52 form a plurality of resilient tongues 44, which may be sprung inwardly and extended into one end of the cylindrical member [801. Since the diameter of the cup-shaped member is substantially equal to the outer diameter of the cylindrical member ltd, it is apparent that portions 35 of the slots 62 will be exposed beyond the adjacent edge of the cylindrical member I811,

i when the cup-shaped member is urged to the limit of its movement into the member ifld. The exposed portions iii of slots will thereby provide means for venting the interior of the cylindrical member 13d within which the reservoir 22 is normally disposed.

Finally, in Figure 10 I have illustrated a conventional type of replaceable erasing element 336. The erasing e ment 33c includes a holder 34c having bent ping arms 6 which engage the abrading ele iont This conventional type of erasi g element may be substituted for the erasing e 7.8111; shown engaged with the cap 25 in Figure 1.

Having thus described various modifications of the elements of my combined pen and pencil, what I claim as new and desire to secure by Letters Patent is:

1. A cap for a combined pen and pencil com prising an elongated, open ended hollow body, a clip for said body including an annular portion engaging about one end of said body, a crimped inner edge on annular portion securing said clip to said body and forming an inwardly directed annular rib on the latter adjacent to and spaced from said one end, and an erasing element in said one end of said body engaging said rib for limiting the movement of said erasing element into said body and for yieldably retaining said erasing element nin said body.
