- the tracing point 18 comes into contact with the extension 44 of the tongue 42, so that a capillary communication is established between the nib 38 and the ink store, through the medium of the tongue 42, the extension 44, and the stem 17, the instrument being able to function in the manner of a fountain pen.
- compensation means are housed inside the nib 38 and/or the bore 37 to retain ink which escapes from the store, for example in the case of a temperature rise.
- FIG. 4 is similar to FIG. 3, but shows another embodiment.
- a tongue 5% with which the nib is in contact, has a descending branch Sll (FIG. 5), which is in contact, by its rear face 52, with a washer 53 made of more rigid capillary material, for example porous material, which has an orifice 54 in the shape of a truncated cone.
- the point is housed in this orifice upon the positioning of the nib device B, thus ensuring a contact of large area between the washer 53 and the branch 51.
- the compensation means 55 for retaining ink form part of the marker A and are operative both when the writing instrument is used as a marker and when it is used as a fountain pen.
- the fountain pen head 64 is adapted to fit on the front end of a writing instrument 61, the writing member of which is made up of a stem 62 terminating in a point 63.
- the head comprises a body 64 having a cylindrical bearing surface 65 cooperating with a shoulder as on the writing instrument til for detachable mounting.
- the head so houses a conduit 67, made up of a core 68 of plastic material of a generally cylindrical shape, having a beveled front face 69.
- the core 68 and the body 64 define an annular gap in which a nib 70 is housed.
- the core 63 has a capillary bore 72 of circular transverse section which is blind at its front end 86 and open at the rear end 7i of the core to receive the point as when the head fill is placed on the writing instrument fit.
- a longitudinal and radial slot 73 opens into the bore '72.
- the slot 73 has an incurved front edge 7s.
- Other longitudinal slots 77 and 78 also open into the bore 72 and have orifices 79 and 80 which are arranged obliquely.
- the ends 81 and 132 of the slots on the front face '71 are spaced from the longitudinal median plane of the core of and the opposite ends have a common juncture with the slot 73.
- the distance between the parallel faces 83 and 34% delimiting a slot is smaller than the diameter of the bore 72, so that the capillary path thus ofiered to the inkas from the point @3 is of a decreasing dimension as far as the nib 7%, which is favorable to controlled feeding.
- the core 90 of the conduit not only has a central bore @ii, blind at its front end and from which there emerges a radial slot 92, but also semicircular transverse grooves 93, four in number in the example shown, namely 93, 93 which contribute to the controlled feeding of the nib.
- the tracer 61 in the embodiment of H65. it and 12, the tracer 61, the constitution of which is similar to that which has been described previously, can be capped by a ball writing device iii) so constituted that the feed of the ball is ensured from the tracing point as.
- the ball writing device lit comprises a tubular body ill having a transverse vent R31 and an external surface 312 which, initially substantially cylindrical, tapers to an ogival or conical end H3.
- the internal surface of the body ill comprises a bore l M adapted to cooperate with the shoulder 66 of the writing instrument, a bore 115 of smaller diameter adapted to cooperate with the cylindrical part 103 of the writing instrument, a bore lid of even smaller diameter, which houses the front end M24 of the writing instrument, and a bore H7. in this bore H7 a ball head 118 is tightly fitted.
- the ball head lid comprises a tubular body H19 in which is mounted a ballpoint 12th.
- the end E21 of the ball point 120 is crimped so as to maintain a ball 1122 at the end of a passage 123. This passage is extended towards the rear by an enlarged part 32 3.
- a stem i2 Housed inside the ball head M8, in its axial passage, is a stem i2, made from a synthetic sponge or similar material having a high coefficient of swelling, for example of the order of five, when it passes from the dry state to the wet state.
- the stern E25 is in contact, at its front face 12s, with the ball 122'.
- the length of the stem is such that, when it is inserted in the passage 123-424 and when its front face 126' is in contact with the ball H22, it protrudes from the rear face E27 of the ball head i138 sufficiently for it to be folded back at its end.
- the folded branch 128 comes into contact with the internal surface E29 of the barrel Hi9.
- the stem When the stem is wet it is also in contact, at its lateral surface H30, with the bore H23 and its front face 1% corresponds closely to the spherical shape of the ball H22.
- the tracing point 63 assumes contact with the curved part K23 which forms the external surface of the fold of the rear end of the stem as shown in dotted lines in FIG. 7. Then, when the device iii comes into abutment at its annular face 133 against the shoulder 66, there is surface contact between the tip of the point 63 and the curved part 132, as shown in solid lines in FIG. 12, the friction developed upon the contact between the branch 12% and the bore 129 opposing a general displacement of the stem 125. The ink can then proceed by capillarity between the point 63 and the ball 122, where it effects the satisfactory feed of this latter for writing.
- the writing instrument can be immediately used as a tracer. if one then caps the tracer with the nib device tit), it can be used as a fountain pen.
- a writing instrument lthl having a tracing point as described above has, on its rear part, a cylindrical projection 101, which can comprise a metallic packing, on which the body of the fountain pen head or of the ball head can be fitted so that, when one wishes to use the writing device as a marker, and when thus its front part is free of the nib head 6%), or of the ball head Hi this latter can be placed on the rear end of the instrument on the projection Mill.
- the fountain pen head or the ball head thus placed on the rear end of the writing instrument can be protected by the usual cap.
- a writing device comprising a writing instrument having a tracing point, ink reserve means connected to said point for capillary feed of ink thereto and a detachable head having a writing member and cpjpillary ink conduction means adapted to cooperate Wlih sai point for the controlled feeding by capillarity of said writing member from said ink reserve means and via said point when said head is mounted over said tracing point.
