STYLOGRAPH File@ F'eb. 24, 1937 :inventors J :Do nner W /lgyncso 'UNITED STATES APATENT OFFICE i smocaarn Julius Donner and Ferenc Jancs, Budapest,
Hungary Application February 24, 1937, Serial No. 127,543 In Great Britain February, 1936 5 claims. (c1. 1204445 This invention relates to improvements in and relating to stylographs or to writing implements in which the inkcontained in a holder is conveyed to a writing point instead of to a nib. A common characteristic of such stylographs is a thin metal nozzle projecting from the taperingend of the holder, from which a thread of ink flows out axially while writing. In this thin nozzle an axially movable thin metal wire is usually located, by which the ink-conducting section of the nozzle is throttled in order that no more4 ink 'may be emitted at the writing point than is required for writing. As with this arrangement the ink can flow out only in the axial direction from the nozzle, -there is the objection that such stylographs can be used' only if writing at a very steep angle. Holding `the stylograph in such a manner is unsuited to most hands and is uncomfoi-table as well as tiresome, at the same time distorting the usual character of the writing.
There are also stylographs known, that have a small knob at the outer end of the thin wire stem located inthe small nozzle. This knob, however,
- is seated on the inside of the orifice of this small nozzle, thus, as with the aforesaid stylograph, permitting thel outflow of the ink only in an axial direction, which again. compels the writer to hold the stylograph at a steep angle.
The stylograph according to the present invention differs from the above mentioned stylographs essentially in that in front of the orifice of the nozzle and overlapping it a small knob is located, so that the ink cannot issue from the tube otherwise than below the knob in a lateral direction radial to the axis of the nozzle. The small knob "may be mushroom-shaped and be seated on a thin and elastic` wire stem xed in the body of the holder and passing through the aforesaid nozzle. As `the stem of the small knob is thinner than the inner diameter ofthe ink-conveying nozzle in which the stem is located, the knob, when the stylograph is `applied to the writing surface, will shift to the opposite side of the small nozzie, leaving a narrow yet sufficiently large slot between itself and the edge of the small nozzle, and through this slot* the ink required lfor writing will now .out below the knob. Owing to this new Way` of ink-outow, the hand may give to the stylographthe desirable slanting position.
People accustomed to the smooth running of the known type of pen which results from its springiness due to its being split into two sections may object to the lack of elasticity f shaped nib of thepointed stylograph. To obvlate' .this inconvenience the .nozzle can be located in a f holders.
lpermitting the ink of the nozzleshort plug of soft rubber or like elastic material, as it is known to do with another type of stylograph. If this plug-shaped elastic piece be introduced into the mouth of the penholder, the nib wiilA give a remarkably soft touch upon the ,Writ- 5 ing surface. This is a very convenient improvement in the use of the pointed stylograph.
Theaccompanying drawing illustrates by way. of example one embodiment of the improvements according to the present invention on a greatly l0 enlarged scale.
Fig. 1 represents the head-piece of the new stylograph in sectional elevation.
Fig. 2 is a detail view of the writing-nozzle on a still more enlarged scale in sectional elevation.
Fig. 3 is a cross-sectional view of the head piece of the holder taken on the line A--A of Fig. 1.
In the orice I of the holder a closely fitting plug 2 of rubber or like material is inserted.- AS bare rubber offers a resistance to slipping move'- 20 ment, the outer Wall of the plug 2 is covered with a thin layer 3 of varnish or another suitable material, so as to permit the rubber piece 2. to slide smoothly in and out of the orifice. Thus if the writing point should not Work satisfactorily or if 25 a different writing point is desired, the plug 2 may easily be removed and replaced by another, in the same manner as nibs in old type pen- Along the plug 2 one ormore furrows l are -cu`t in the rubber piece connecting the ink 30 supply chamber of the holder with the open air. An ink conduit pipe 5 of rigid material, such as hard rubber or the like, is located in the soft plug the holder is turned downwards, the ink conveyed from the ink supply chamber of the holder 40 below the writing knob 8 through the conduit pipe 5 and the nozzle G is able to ooze out sideways from the circular slot 9 formed by the outer edge of the nozzle 6 and the inner edge of the writingI knob 8. During the writing. process the knob 8, 4.5 applied to the paper or other writing surface is shifted from the centre towards the periphery of the nozzle, with the result that on the spot where writing point and writing surface meet ink will ooze out directly and any layer of dried ink eventually sticking in the slot 9 will be ripped up,a
behind to ooze out freely.
The oscillating movement of the tiny knob 8 while writing actively helps the oozing out of the ink in the required amount.
5, and immovably fixed therenozzle a wire stem provided with a small knob on` its outer end, the said small knob being seated in front of the orifice of the nozzle and overlappingA it, and having an ink conduit pipe,`and a removable plug of elastic material fitting closely in the mouth piece of the holder inside which the ink conduit pipe is mounted, whereby said nozzle is yieldingly supported for oscillatory movement while writing.
2. A stylograph according to claim 1, characterized in that at least one air-conducting furrow is cut along the plug.
3. A stylograph according to claim 1, characterized in that the outer wall of the rubber plug is covered with a thin layer of a material permitting the rubber piece to slide within the mouth piece of the holder.
4. A stylograph according to claim 1, in which the plug is retained in the holder solely by the elasticity of its material.
5. In a stylograph, an ink chamber and a plugA substantially closing the chamber, a small tube for supplying the ink from the ink chamber to the writing surface, a small knob seated in front of the orifice of the small tube andoverlapping the same leaving a narrow but sufliciently large slot between the knob and the edge of the small tube for the outflow of the ink, the writing ink being adapted to flow out along the small knob in a lateral direction, a short wire stern arranged in said tube to which said small knob is fastened and said plug having channels extending along the orifice of the writing point through which the air can pass into the ink chamber of the writing point, said air replacing the ink used when writng.`
