Description

Pen with a <B>Tip</B> formed <B>by</B> a ball. Fountain pens with a krire tip consisting of a ball closing an orifice have either a ball. crimped Jans a housing, or a ball held in position by a support ergane. These latter fountain pens generally have a support member comprising an axial per@age allowing the ball to be fed with eure. It is clear that this ball plugs the end of this channel, so that the space in which the ball is located is empty of ink during the work. To write, the user only has the remaining film of ink adhering to the ball and then begins to rotate the ball in front of this channel. However, it has been recognized that the flow of the ink is irregular and cannot give complete satisfaction.

The subject of the present invention is a stylus whose tip for writing is constituted by a ball closing off an orifice supplied with water coming from a reservoir and (whereby the play of the ball, which determines the flow rate in ink, is determined by a bearing surface for the ballpoint. This fountain pen differs from known stylographs in that the bearing surface is located on the axis of the stylograph, the space in which is arranged the ball being directly and permanently connected to the ink reservoir by at least one channel located outside the fountain pen.

The accompanying drawing schematically shows a longitudinal sectional view of a fountain pen according to the invention. The typograph has, like Frostar other known fountain pens, a cylindrical casing or sheath 1 tapering at one end.

This casing protects an ink reservoir 4 carrying, rigidly fixed on its end, an intermediate piece 6. of the casing 1. This tubular member 7 has an axial cylindrical channel 9, the end of which is narrowed and opens to the outside through an orifice 10 whose section is smaller than that of the channel 9. The orifice 10 is closed by a ball 11 whose first diameter is slightly larger than that of Porifice 10. This ball 11 is held in position by a support member 12<RTI ID="0001.0274" WI="14" HE=" 4" LX="1539" LY="1505"> secured to the pike 6. Drillings 14 are practiced in the support member to permanently and directly connect the first reservoir 4 to the channel 9. These drillings are located apart from Faxe to the fountain pen. The ball is supported by a point located at the fax of the fountain pen on the support member 12.

Thanks to the arrangement described of the perga.- ges 14, the channel 9 is always full of water whenever the ball is in contact with it through all of its portion of the sphere located at the end of the conical part of this channel 9 Thus, his entree feed is always regular and amply sufficient.

A form of execution of the pen object of the invention has been described here, as

example and with reference to the appended drawing, but it is obvious that the bodies and devices d @ erits can without other eire c6s replaced by leum equivalents. 0n could, for example, provide a support member come dune pike with part 6 or reservoir 4. In this case, channels or openings can wind be practical apart from faxing a fountain pen. These channels may also have come from dangling. The support member could also be made integral with the organ, not tubular 7.

Claims (3)

CLAIM Pen whose tip for krire is constituted by a ball closing off an orifice supplied with euere coming from a reservoir and in which the play of the ball, which determines the first flow of euere, is determined by a bearing surface of the ball , characterized by the fact that the support surface is located in the fax of the fountain pen, the space @in which is di: 3 placed the ball being directly and permanently connected to an ink reservoir by at least one channel located outside the axis of the pen.
