INVENTOR G0ly flflo5l zyr A; 4 TTORNEVS GEORGE N. HOSINGER, OF JERSEY CITY, NEW JERSEY.
STY'LOGRAPHIC PEN.
Specification of Letters Patent.
Patented Apr. 8, 1919.
Application filed January 24, 1918. Serial No. 213,513.
To all whom it may concern Be it known that I, GEORGE N. HosINoER, a citizen of the United States of America, and resident of Jersey City, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Stylographic Pens, of which the following is a specification.
This invention relates to improvements in stylographic pens.
It is the purpose of the invention to provide a smooth and evenly writing stylographic pen of simple and durable construction and in which the usual air-tube which extends into the ink-reservoir is dispensed with. By thus dispensing with the air-tube the capacity of the reservoir to hold the ink is much increased and the frequency with which the reservoir has to be refilled is correspondingly diminished.
It is a further purpose of this invention to provide such a construction of the airpassage or passages that while freely delivering air to the reservoir to maintain a steady and uniform flow of the ink to the needle the ink cannot he accidentally ejected in spurts through the air-passage to make blots on the paper.
It is a further purpose of the invention to so combine the ink-feed, the air-feed, and the needle that no resistance of the air as a bubble, film, or air-cushion, shall be formed to interfere with the constant and uniform flow of the ink to the needle-point when writing.
I have illustrated my invention in the accompanying drawin designating the parts by numera s and re erring to like parts by like numerals.
Figure 1 is an elevation of a stylographie pen partly in section.
Fig. 2 is a horizontal section thereof taken on the lines 22.
Fig. 3 is a detail of an internal member, while Fig. 4 is a right angular View of the structure shown in Fig. 3.
Fig. 5 is an elevation of the tip.
Fig. 6 is an elevation of the parts 5 and 8 assembled with the ducts 7 and 15 in alinement.
Fig. 7 is an elevation of the parts 5 and 8 assembled with the ducts 7 and 15 out of alinement.
Fig. 8 is a section on line BB, Fig. 1, looking in the direction of thearrows.
Fig. 9 is a section on the line CC, Fig. 1, in the direction of the arrow.
Figs. 10 and 11 are sections taken on the line 33 Fig. 1, Fig. 10 looking in the direction of the arrow D, and Fig. 11 in the direction of the arrow E.
Fig. 12 is the same as Fig. 11, except that the aperture or duct 7 is turned out of the position shown in the former figure.
1 is the barrel of the pen closed at the upper end and screw-threaded at the lower.
end as at 2, the hollow interior thereof as 3 serving as the reservoir. A screw-threaded tip 4 is tapered in line with the exterior of the stem 1 and is externally screw-threaded to enter the screw-threaded aperture 2 of said stem 1. Said tip 4 is also internally screw-threaded to receive the point 5, the latter being illustrated in Fig. 5, where it will be seen that a peripheral enlargement 6 is provided thereon which is screw-threaded and that there is an aperture or duct 7 running through said screw-threaded section. 8 is a cylindrical member viewed in two right-angular positions in Figs. 3 and 4:. It is externally screw-threaded and provided with the aperture or duct 9. 10 is a loaded rod carrying at the end thereof a needle point 11 adapted to reciprocate in a duct 12 at the end of the point 5. When. the parts are assembled as shown in 1, it will be noted that there is a duct as 7 leading from a point adjacent of the tip in a line parallel with the axis of the stem to a chamber 13 formed around the part 14. of the tip 5 and between that part and the wall of the tip 4, said chamber being closed by the lower part of the cylindrical member 8 when the same is screwed into the conical tip 4. In view of the fact that the cylindrical member 8- is longitudinally slotted as at 9 the portion of such slot indicated as 15 forms a duct parallel with the axis of the stem and leading from the chamber 13 to the ink reservoir. It is within the scope of my invention that the ducts 7 and 15 should be in line to form a continuous duct between the atmosphere and the reservoir. On the other hand while it is essential that they should be parallel it may be desirable in some instances that they should not be in line, that is to say, one
opposite the other, in which case the duct 7 leads into the chamber 13 and the duct 15 leads from the chamber 13 into the reservoir, but not necessarily directly in line with the duct 7.
I claim nothing new in the general construction and operation of the stylographic pen here described, except in so far as I have arranged the ducts 7 and 15 and chamber 13.
I am aware that structures have been arranged wherein the air has been led throng1 a duct as 7 into a chamber as 13 and wit drawn from said chamber 13 into the reservoir from a point opposite that of the point of intake and in a line at right angles to the axis of the stem, as for instance in the United States patent to William W. vSanford, No. 698,859, pat. April 29, 1902. In such structures I have observed that the channels through which the air is thus brought to the reservoir become clogged resulting in the inefficient operation of the pen, Whereas in the arrangement of ducts which I have arranged, that is to say, where the ducts are arranged parallel with the axis of the stem leading through the chamber 13 to the reservoir a much more efficient and certain result is accomplished. Furthermore with such ducts it is possible in an unlimbering of the pen to Wash out or cleanse said ducts should the same for any reason become clog ed, but my experience is that they do not become clogged and that highly beneficial results are obtained by this arran ement.
hat I claim and desire to secure by Letters Patent is 1. A stylographic pen having an annular air chamber interposed between the ink reservoir section and the point or stylus section, a duct parallel With the axis of the pen and leading from a point adjacent said stylus point to said air chamber, a second duct also parallel with the axis of the pen and leading from said air chamber directly into said reservoir.
2. A stylographic pen having an annular air chamber interposed between the ink reservoir section and the point or stylus section, one end of said chamber being open, a duct parallel with the axis of the pen and leading from a. point adjacent said stylus point to the closed end of said air chamber, a cap adapted to fit over the open end of said air chamber to close the same and a duct leading through said cap from the air chamber to the reservoir, said duct being parallel with the axis of the pen, said cap being rotatable on its axis so that the duct therein may be adjusted to take air from said air chamber at any point in its circumference.
