Description

July 3, 1951 N. ZEPELOVITCH 2,559,555
WRITING INSTRUMENT Filed July 12, 1949 A/afhan ze oelovil'ch INVENTOR.
Patented July 3, 1951 WRITING INSTRUMENT Nathan Zepelovitch, Tel Aviv, Israel, assignor to Nahum A. Bernstein, New York, N. Y.
Application July 12, 1949, Serial No. 104,311 In Israel March 31, 1949 The present invention relates to writing instruments of the fountain pen type, i. e. to instruments comprising a barrel constituting the ink reservoir and a writing tip which is incorporated in a feed member inserted in and in communication with the inside of the reservoir. More particularly the invention relates to writing in struments of the type where the writing tip is constituted by a narrow tube. It is known to provide these instruments with sleeves or caps having a central hole in their top, such caps be- 3 Claims. (Cl. 120-42.03)
ing axially displaceable on the barrel, towards and away from the writing tip, which latter emerges, in one extreme position, from the hole in the top of the cap or end of the sleeve, thus being in writing attitude, while in the other extreme position the writing tip is retracted in the cap and shrouded thereby, so as to be safeguarded against being spoiled or damaged. The known writing instruments of the latter type are provided with a clip arranged at the end of the barrel which is opposite the writing end. When carried in the pocket as usual, the writing instrument is reversed and the Writing tip is pointing downwards, so that the likelihood of ink leaking into the pocket is always imminent. Further, although the tip is enclosed by the said cap or sleeve, dirt and fluff can easily enter the opening of the cap, which is objectionable.
It is the object of the present invention to provide a writing instrument which may safely be carried in the pocket and which is not exposed to dirt entering the Writing tip.
According to the present invention, a writing instrument of the kind referred to is provided with an axially displaceable sleeve or cap, the instrument being for that part of its length on which the cap slides, of restricted diameter, so that with the cap in forward position (shrouding the writing tip) a circumferential groove is created on the writing instrument. Into this groove is easily detachably inserted a springy, flat, split ring forming part of a clip by means of which the writing instrument can be fastened to the hem of a pocket. It will be seen that with this arrangement the writing instrument is held upside, so that no dirt can enter the aperture of the cap and there is no likelihood of a garment becoming ink-stained by ink flowing into the pocket. The clip is destined to remain permanently on the hem of the pocket and the pen is fixed thereto by causing the springy split ring of the clip to engage in the groove laid open by the forward moved cap. In the position within the pocket, 1. e. with the cap in forward position, the ring prevents the cap or sleeve from being unintentionally retracted, thus laying the writing tip open.
The cap, or part thereof, may be of resilient material and the central hole may be of such diameter that with the Writing tip in retracted position, it will be closed for all practical purposes and will open only when the material yields to the penetration of the writing tip being forced therethrough.
The invention will now be described referring to the annexed drawings showing in Fig. 1 the upper part of a writing instrument of the said kind, partly in section, with cap and clip in the closed position of the instrument; Fig. 2 shows the same instrument in writing position without the clip; Fig. 3 shows the detached clip; Fig. 4 shows a modified form of the clip; Fig. 5 is a top view of the clip; Fig. 6 is the top part of the cap in a modified form on an enlarged scale, partly in section.
The writing instrument itself is of known construction. To its barrel 1 is attached, by being inserted therein-as usualthe feed member 2 carrying the writing tip formed by a narrow tube 3. The lowermost part 4 of the feed member is of a smaller diameter than that of the barrel I. It has two parallel circumferential grooves 5, 6. On feed member 2 slides a cap 1 having in its top a central opening 8, wide enough for the passage of tip 3. The lowermost part of sleeve 1 has an internal annular bead 9 which can be engaged by grooves 5 or 6, thus fixing the sleeve in one or the other position.
A split springy ring 9 fits on part 4; attached to it is a clip II).
In position according to Fig. 1, e. g. being carried in a pocket, the cap is in a forward position, bead 9' is engaged by groove 6 and the writing tip is shrouded by the cap. Between the lower edge of the cap and the upper edge of barrel I a circumferential recess is created by part 4. In this recess is accommodated the split ring 9 and the instrument can easily be clamped to the hem of a pocket by means of clip H) integral with ring 9.
For use the instrument is detached from the clip and ring which remains clamped to the pocket hem, the cap is retracted, thus uncovering the writing tip, engaging at the same time with bead 9 the groove 5. The retraction of the cap remains impossible, so long as ring 9 is in recess 4. I
Fig. 4 shows the clip Ill being of slightly different shape and differently fixed to ring 9. This figure is self-explanatory.
In Fig. 6 the central opening of the cap is closed by a resilient plug l I, e. g. of India rubber. This plug has a fine opening in its centre. This opening widens conically towards the inside of the cap. When the writing tip 3 is forwardly moved, i. e. forced outward, the material yields and the tip emerges freely from the opening. When retracted, the opening closes and the writing tip is completely sealed off from the open. The whole cap could of course be made from appropriate yielding material.
What I claim is:
1. A writing instrument, comprising, a tubular barrel member, a feed member supporting a'writing tip secured to one end of the barreh member; said feed member having a restricted portion thereof disposed adjacent said barrel member, an axially displaceable capslidably mounted on said feed member adapted to shroud said writing tip when in an advanced position and to expose said writing tip when in a retracted position, a springy split ring sized to slidably encompass said tubular barrel member and adapted to be positioned encircling'said restricted portion of said feed member for maintaining said cap in advanced position shrouding said writing tip, and a clip member secured to said ring and, mounted thereon with the gripping portion thereof extending away from said writing tip, whereby said writing instrument is adapted to be carried with the writing tip upwardly disposed and shrouded by said cap.
2. A writing instrument as set forth in claim 1, wherein the axially displaceable cap is provided with a deformable unitary closure member having an opening in axial alignment with said writing tip, said opening having a diameter smaller than the diameter of said tip and adapted to deform and yieldingly encompass said tip whenever said tip is forced therethrough.
3. A writing instrument, comprising, a tubular barrel member, a feed member supporting a writing tip secured to'one end of the barrel member, said feed member having a restricted portion thereof disposed adjacent said barrel member, a; pair of circumferential grooves bounding said restricted portion of said feed member, an axially displaceable cap slidably mounted on said feed member and provided with an annular bead adapted to engage one of said grooves when said cap. is inanadvanced position shrouding said writing tip and adapted to engage the other of said grooves when said cap is in a retracted position exposing said writing tip, and a clip mounted on a springy split ring shaped to encompass said tubular barrel member and to be positioned encircling said restricted portion. of said feed member for maintaining said cap in advanced position shrouding said writing tip.
