- the present invention relates to a fountain pen. More particularly, the invention relates to a fountain pen provided with a novel cap capable of securely holding the clip and of effectively sealing the pen when the cap is secured thereon.

It is well known to provide inner sleeves or inner caps which will provide a shoulder cooperating with the end of the barrel in order to seal the pen. However, these inner caps which are generally held in place by means of a suitable cement, are prone to break away from the material of the cap itself. In this type of fountain pen cap, a plug member is screwed into the end thereof in order to retain a grip, and considerable diificulty has been encountered in providing threads in the cap to receive the plug member. During the threading of the cap, in many cases, the inner cap or sleeve tends to become loose and this is true even though the inner cap or sleeve is held by a suitable cementing medium.

May 30, 1950 KAHN FOUNTAIN PEN CAP Filed Dec. 28. 1945 Patented May 30, 1950 UNITED STATES PATENT QFFICE.
Application December 28, 1945, Serial No. 637,556
7 Claims. 1
The present invention relates to a fountain pen. More particularly, the invention relates to a fountain pen provided with a novel cap capable of securely holding the clip and of effectively sealing the pen when the cap is secured thereon.
Fountain pen caps are usually made of relatively thin plastic material and considerable difficulty has been encountered heretofore in securing the clip to the cap, and in providing a cap which will effectively seal the pen when the cap is screwed thereupon. It is well known to provide inner sleeves or inner caps which will provide a shoulder cooperating with the end of the barrel in order to seal the pen. However, these inner caps which are generally held in place by means of a suitable cement, are prone to break away from the material of the cap itself. In this type of fountain pen cap, a plug member is screwed into the end thereof in order to retain a grip, and considerable diificulty has been encountered in providing threads in the cap to receive the plug member. During the threading of the cap, in many cases, the inner cap or sleeve tends to become loose and this is true even though the inner cap or sleeve is held by a suitable cementing medium.
It is one of the objects of the present invention, therefore, to provide a fountain pen cap member with a novel inner cap or sleeve capable of receiving the plug member for retaining the clip on the cap.
Another object of the present invention is to provide a fountain pen cap having an inner capor sleeve member having means thereon for preventing relative rotation of the inner cap and the cap proper.
Still another object of the present invention is to provide an inner cap member constructed to be wedged into the outer cap member and securely held therein, and further provided with a series of grooves capable of holding cement or other uniting material.
A fourth object of the present invention is to provide an inner cap member for a fountain pen cap having formed therein opposed bores, one
of said bores being adapted to receive a pen nib, and the other bore being provided with threads for receiving a plug member which serves to retain a clip on the cap.
A fifth object of the present invention is to provide a cap and inner cap structure wherein the inner cap is adapted to become firmly wedged within the outer cap.
A sixth object of the present invention is to provide an outer cap and inner cap assembly for a fountain pen wherein a pair of cooperating shoulders on the inner cap and outer cap serve to definitely position the inner cap within the outer cap so that the top of the inner cap will be flush with the top of the outer cap when said members are assembled.
A seventh object of the present invention is to provide inner and outer cap members so constructed as to form a firm seat for a. portion of a clip member when the same is mounted on the cap.
Other objects and advantages of the present invention will become apparent from the following description taken in connection with the figures of the drawing, wherein:
Fig. 1 is a vertical section of a fountain pen cap and inner cap assembly according to the present invention;
Fig. 2 is an elevation of the inner cap member;
Fig. 3 is a vertical section of the inner cap member;
Fig. 4 is a bottom plan View of the inner cap member;
Fig. 5 is an enlarged vertical section of the outer p;
Fig. 6 is a detail of the threaded plug member;
Fig. 7 is a perspective detail of the upper end portion of the clip; and
Fig. 8 is a top plan view of the cap assembly with the plug and clip removed.
Referring to the figures of the drawing, and particularly Fig. 1, a fountain pen cap and clip assembly is indicated in general at if]. The cap til is adapted to receive a fountain pen which is indicated in dotted lines and designated by the reference character P. The fountain pen P is provided with a usual nib l I and is adapted to be threadedly received Within the cap in the usual manner so that the end of the barrel indicated at 12, abuts a shoulder within the cap for effectively sealing the pen. The fountain pen cap ll] consists of two principal parts; an outer cap member l3, and an inner cap member 14. The outer cap member I3 is provided with a bore l5, having the outer threads 16 formed therein for threadedly receiving the fountain pen barrel. The bore l5 tapers inwardly slightly at its upper end and terminates in a counter bore l l which serves to provide a shoulder is for a purpose to be hereinafter described, Above the shoulder is a somewhat tapered bore I9 is provided which terminates in a relatively straight bore 20, as shown particularly in Fig. 5 of the drawings. The inner cap or sleeve member M is fitted within the bores just described so that the upper end of the inner cap or sleeve member H3 is flush with the upper end of the outer end of the cap it, the two caps together serving to form a seat for a ring member 2| forming the upper part of a clip 22. The inner sleeve member 14 is provided with a series of ribs 23 forming a series of grooves 24, for a purpose to be hereinafter set forth.
Above the ribs the inner cap member [4 is provided with a generally tapered portion 25 terminating in a reduced end portion 26 thus forming a shoulder indicated at 21.
As shown particularly in Fig. 3, the inner cap member or sleeve I4 is also provided with a pair of opposed bores 2e and 29, the lower of which,
the bore 29, is adapted to receive the pen nib as 2 shown in Fig. l, and the bore 28 is provided with threads to threadedly receive a plug 30, best shown in Fig. 6.
The plug 30 is provided with a button 3| and .a reduced threaded portion 32. The caplil may also be provided with an ornamental ring of metal indicated at 33. The inner and outer cap are each preferably integrally moulded of a suitable plastic material such as cellulose nitrate, cellulose acetate, or other plastic materials well known in the pen art.
The inner and outer cap members are preferably assembled by coating the grooves 24 with a suitable cement, such as a solvent solution of cellulose acetate or cellulose nitrate, and thereafter the inner cap or sleeve member is driven into the outer cap or sleeve member until the shoulder 21 abuts the shoulder I8. Preferably the relatively straight portion or bore 29 at the upper end of the outer cap is initially slightly smaller than the reduced portion 26 of the inner cap. Therefore, during the assembly of the inner cap and the outer cap a firm friction seat is established at the upper end of the inner and outer cap members. In addition, the portion provided with ribs 23 is slightly larger than the straight inner diameter of the bore l so that the ribs are firmly wedged against the inner bore of the cap. The ribs, in addition to providing the grooves 24 for receiving the cement therefore, also provide a means for preventing relative rotation between the inner and outer cap members. After the inner and outer cap members are thus assembled, the ring portion 2! of the clip 22 is seated upon the upper surface of the assembled cap and screw threaded portion 32 of the plug 301's then threaded into the screw threaded bore 2-8 of the cap. The action of the plug, therefore, serves to adequately firmly hold the inner cap within the outer cap.
It is to be noted that the inner and outer cap together form a relatively wide surface at the upper end of the cap assembly. The ring member 2| can therefore be made much wider than those conventional in the art, and the screw threaded portion 32 is therefore relatively smaller. Since the ring member and clip are usually stamped from relatively thin metal, this has been found to greatly reduce the breakage during the manufacture of the clip.
