For the purpose of easy cross references between the description of each preferred embodiment of the present invention, the same reference and affixed (when required) 10 with alphabetical captional letter designates with the same portion or similar components of the present invention.

It should be explained first that the present invention is to be equiped with water based ink, the reason is that water based ink could fit fountain pen point nib, soft pen 15 nib, plastic pen nib and ball pen nib at the same time under the guide of uniform ink flow system of the present invention_ As shown in the Figs. 1 and 2 , the multi-combination writing instrument of the present invention comprises a 20 main nib device (hereinafter called mother nib device) 10 and at least one set of different or same nib device (hereinafter called sub-nib device) 10A capped on said mother nib device 10 and a pen holding means 20. Mother nib device 10 which is immediately c onnected with the pen 25 holding means 20, includes a nib body 11 having a male coupling portion 13 at the front and a female coupled cavity ft - 5 - ■' . ... ... ..... • /k \ . t' 206010 14 at the rear. At the front of nib body 11 is a fitting hole 111 for fictional receiving the writing point 12. On the male coupling portion 13 is provided an annular matching convex ring 131 (or concave groove), and inside the coupled 5 cavity is an annular matched concave groove 1^1 (or convex ring) which is served to match with the convex ring 231 on the front portion of the pen holding means 20 or with the convex rings 131A, 131B of male coupling portions 13A, 13B to make the mother nib device 10 snugly cooperate 10 with pen holding means 20 or with sub-nib devices 10A, 10B perfectly. The construction of sub-nib devices 10A and 10B is same as that of the mother nib device 10 so that their related descriptions are thus omitted. Nib body 1 1 of mother nib device 10 is insertable into the rear portion 15 of sub-nib device 10A or 10B, such as the another fountain pen nib 12 or ball point pen nib 12A or soft pen nib 12B (as shown in Figs- 1 and 2). In the fountain pen nib 12, the pen nib 121 has an ink inducing member 122 with an air vent 18 to guide ink to fountain pen point for writing. At 20 the center of the body of ball point pen nib 12A an ink inducing member 122A and an air vent 18A are provided to induce ink to the ball penpoint for writing. • As for the writing point 12B of soft pen, it is inserted at nib body illBby an ink inducing core 122B and outside of which two 25 diametrically disposed air vents 18B-18B are provided.

Referring to Figs. 1 and 3, the pen holding means 20 ;! ; - 6 - tii 2 06 0 10 of the present invention is similar to that of the conventional fountain pen including an ink reservoir 22 at the rear and a capillary tube 21 at the front, however, the important feature of present invention is to form a central ink inducing means by inserting a longitudinal ink inducing core 212 into the relatively smaller diameter portion 211 of capillary tube 21 and to cut a capillary groove 213 (see Fig. 3) on the middle portion of capillary tube 21 which the front edge of said capillary groove 213 only terminates at the middle^ of the front smaller diameter portion 211 and communicates with the rear end of said ink inducing core 212 and the depth of said capillary groove 213 should be enough to reach the front end of an ink conducting pipe 215 which is extending through the central hole 214 so that ink will flow from the rear of pipe 215 to the utmost front end of said core 212 through said . capillary groove 213 with the aid.of air channel 216 to form a part of uniform ink flow system of the present invention.

Due to a greatly fictional fit between the frond end of said pen holding means 20 and the front smaller diameter portion 211 of said capillary tube means 21 and the core 212 making no substantial contact with said pen holding means 20, no ink leakage will be occurred. In this manner, ink in the ink reservoir 22 will flow through the capillary tube means 21 then again through the ink inducing member 2060 1 212 without making any ink leakage. The front portion of pen holding means 20 is formed with a relatively smaller diameter engaging portion 232, on its outer surface a matching convex ring 231 (or concave slot) is served to combine with the mother nib device 10 into the engagement portion 232. Thus ink. will flow from the ink reservoir 22 through the capillary groove 213 of the capillary tube means 21 to the ink inducing member 212 then guide;to writing point 12 for immediate writing.

The advantage of present invention is to provide the mother nib device 10 connecting with the pen holding means 20 to equip with at least one more same nib device or with different type of nib device 10A, 10B so "as" to conjunct each writing point 12, 12A, 12B of mother nib device or sub-nib device 10, 10A, 10B respectively with the front of the capillary tube means 21 or the front part of writing point 12, 12A, 12B or through the additional ink conducting member (will be described hereinafter) to guide the ink for immediate writing.

As shown in Figs. 1 and 2, foran example, we take fountain pen point 12 for mother nib device 10 and conjunct with pen holding means 20. At the front of mother nib device 10 is capped with another ball pen point 12A of sub-nib device 10A. Again, one more sub-nib device 10B with soft writing point 12B is further capped on said sub-nib device 10A. The fountain pen point 12 of mother nib -■8 - * ' ' " - , " ■ r , . . hi/ . - ' ■ ' • ■ ' , , > \ _ s | >• » ^ r^'A. "* *■ * '' 1 2 device 10 has an ink inducing member 122 fluid connected with the ink inducing member 212 of capillary tube means 21 in pen holding means 20. The rear part of ball'pen'point 12A is connected with fountain pen point 12, and the same 5 situation the back part of soft pen point 12B is connected with ball pen point 12A. Ink in ink reservoir 22 is flowing through capillary tube means 21 to the fountain pen /—"S point 12, then again through the fountain pen point 12 to the ball pen point 12A, finally ink is led from the ball 10 pen point 12A to the soft pen point 12B for immediate writing. Under the circumstance, it is to be understood that to change the writing function, it only need to take off the soft pen nib 10B and to use the ball point pen 12A for writing; to take off the ball point pen 10A and to 15 write by fountain pen point 12. In addition, it is also possible to replace ball pen point 12A or soft pen point: 12B with fountain pen point 12 for different writing purposes. Also the writing instrument of the present invention could be equipped the same function nib device 20 but with a series of different gauges of the same.nib . device to perform an engineering or artistic creation (Tj drawings,such as different fineness of solid lines and hatching and shading lines.

It is to be understood that the junction of the rear 25 end of sub-nib device 1 OB and the front end of sub-nib device 10A, as shown in Fig. 2, all of the exposing . -. 9"- :■ 2 060 1 0 portion of rolling ball point 12A of sub-nib device 10A is completely inserted into and touched with the rear end of soft ink inducing member 122B to surely establish the ink flow and to induce ink from the ink reservoir to the utmost front writing point 12B and thus constitute a part of uniform ink flow system of the present invention.

In the Fig. 4A, it shows a second combination of nib device of the present invention, the nit device consists of two fountain pen nibs, 10-10 and one ball pen nib 10A or one soft nib device (not shown)- at the front end. Regarding Fig. 4B, it shows a third combination of nib device of the present invention, wherein ball point pen nib 1.0A acts as a mother nib device and soft pen nib 10B and fountain pen nib 10 as a sub-nib device. In this manner, to change their connection sequence individually and mutually are also considered to be obtainable the same purpose of the■ present invention mentioned above.

To further effect the uniform ink flow of the present invention mentioned above, there an ink conducting member which is made of a soft and an ink guiding -material, such as synthetic fiber or filament, is provided at the rear of each nib device for enlarging the contact area of the writing point with ink conducting member. As shown in Fig. 5 each rear portion of nib devices 10, 10A, 10B is further provided a larger contacting portion of ink conducting members 122' 122A' 122B^ after assembling the x. o ^ Y s"- ] 1 ^ - t ^ wV ^ ' ' > -l 206010 utmost front v/riting point of each next behind successive nib device is effectively inserted into the substantial portion of the rear end.of each next front successive nib device. In this way, even clearance between each two nib 5 devices or pen holding means is somewhat varied from lot to lot during manufacturing, it will not affect the smooth ink flow within the uniform ink flow system of multi-com-bination writing instrument in accordance with the present invention. The rest of components are almost same as the 10 first embodiment mentioned above and the related illustrations are omitted accordingly.

The nib body 11 of nib device 10 in accordance with the present invention could be also constructed as shown in the Fig. 6A. That is to equip a writing point inserting 15 member 16 and a writing point holding body 17 on the nib body 11 of nib device 10. At the front body of writing point holding body 17 is a junction hole 17,2 with an engaging channel' or screw unit 171 and after insertion the writing point 12, the tail portion of the writing point 12 20 be connected with the pen point of the next rear nib device or the capillary tube 21 of pen holding means 20. At the inner side of pen point holding body 17 are forming a junction convex ring 173 (or concave slot) to match the junction inserting member 16 and become the replaceable 25 nib device or equip to the pen holding means 20.

As shown in the Fig. 6B, the nib body 11 of nib device '■J ... . . .v : ■ •->'' \ ' - > \ 1 t L 2 & tr ■ ■{. "%:■ -k P, of the present invention also made a fitting hole 111 with a smaller open bottom end 112 to equip the ink conducting member 15, to communicate with the rear end of fountain pen nib 12 or ball pen nib 12A or soft pen nib 5 12B to further accomplish a uniform ink flowing effect.

In this manner, it can also be served as the sub-ink reservoir to increase the ink reserving function by the ink conducting member 15 to thereby make a further smooth p' writing.

The air vent 26 of present invention is made on the pen holding means 20. Of course the air vent 18 can also be made on the nib body 11 of each nib device 10, 10A, 10B as shown in Fig. 5, and attain the same effect.
