STYLOGRAPHIC PEN.

Application filed October 7, 1910. Serial No. 585,780.

Specification of Letters Patent.

1 two diametrically disposed grooves 18, duct is also diametrically arranged, its axis coinciding substantially with a line connecting the grooves. A tubular plug 21 removably fitted into the upper end of nozzle 12, prevents an undue longitudinal movement of the bar, without impairing a free flow of ink from the holder toward the same.

In use, the ink will flow downward along longitudinal grooves 18, and fill circumferential groove 19, as well as duct 20. This groove together with the duct will thus form supply pockets from which the ink is at all times freely delivered over coniform head Be it known that I, JACOB Unnnion, a citizen of the United States, residing at Hoboken, county of Hudson, 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 a stylographic pen of novel construction, and more particularly to novel and eflicient means for supplying the stylo with an ample charge of ink and insuring the necessary air pressure in all positions that the pen may assume during writing.

15 In the accompanying drawing: Figure 1 16* to the stylo in ample quantity.

is a plan of a stylographic pen embodying The correlation of the parts is such that my invention; Fig. 2 an enlarged longituvent 15 is alined with and opens into cirdinal section through the lower part therecumferential groove 19, so that. at all posiof; Fig. 3 a perspective view of the ink feed tiOnS of the-bar, the air may freely ascend 2 bar, and Fig. 4 an enlarged end view of the through said groove, and through the then nozzle. uppermost longitudinal groove 18, into the To the lower end of the tubular holder 10, holder 1 t0 fllllllsh the necessary Pressureis connected by a screw joint 11, a nozzle 12, I clalmf I that carries the usual tubular metal tip 13. A stylogl'aphlc P P I P a 5 Th upper ti f nozzle 12 overhangs holder, a nozzle, and a feed bar within the nozzle, said bar being provided with a tapering head, a longitudinal groove, a communicating lower circumferential groove, and a transverse duct opening at both ends the lower section to form a downwardly opening circumferential groove 14, into which opens a vent 15. The stylo or needle 16, which projects through tip 13 is secured to the lowe coniform head 16 of a freely into the circumferelltifll movable feed bar.17, said head finding a A stylogmphlc P pr p bearing against an inner tapering wall of holder, a nozzle, and a feed bill Wlthln the lower nozzle section. The stem or main body of bar 17, is provided with a suitable number of longitudinal surface grooves '18, two diametrically disposed grooves being shown. At their upper ends, these grooves extend to the top of the bar while their lower ends communicate with a circumferential surface groove 19 of the bar formed directly above head 16*. Finally there extends through the bar a transverse duct 20, opening at bothends into groove 19 opposite the lower ends of grooves 18. Thus with nozzle, said bar being provided with a tapering head, a pair of diametrically disposed longitudinal grooves, a communicating lower circumferential groove, and a transverse duct that enters the circumferential groove and connects the lower ends of the longitudinal grooves.
