SELF-FILLING FOUNTEN-PEN.

Specication of Letters Patent. Patmfbd Jem@ 141, Q.

Application led November 22, 1909. Serial No. 529,229.

To all lwhom it may concern:

Be it known that I, JOSEPH ANTHONY VOGELMANN, a citizen of the United States,

residing at Brooklyn, yin the county of Kings and State of New York, have invented certain new and useful Improvements in Self- Filling Fountain-Pens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to improvements in fountain pens.

One object of the invention is to provide a fountain pen having means Wherr'iy ink maybe readily drawn up into the barrel of the pen, said means being attached to and formin a part of the pen.

Anot er object is to provide a pen of this character which willbe simple, strong and durable in construction, efficient and reliablle in operation and which will not leak 1n l With the foregoing and other objects in view, the invention consists of certain novel features of construction, -combination and arrangement of parts, as `will be more fully described and particularly pointed out in the appended claim.

In the accom anying drawings, Figure 1 is a side view o a pen constructed in accordance with my invention; Fig. 2 is a longitudinal sectional view showing the parts in closedor operative position; Flg. 3 is a similar view showing the parts in osition for drawing ink into the pen barre Fig. 4 is a cross sectional view on the line 4 4 of Fig. 1. i .My improved pen comprises a barrel or 7 in the outer end of which is formed anair position, the .inner end of the same is v adapted to t into `closeengagement with the shoulder 11 formed by the reduced outer portion A2 of the barrel, and when the suction tube is thus closed into enga ment with the shoulder `1l, `the outer sur ace of the tube will be {iush with the inner end portion of the barrel and said barrel will thus present a smooth outer surface.

In the outer end of the reduced portion 2 of the pen barrel is formed a threaded passage 12 in which is adapted to be screwed a plug or threaded pin 13, which projects through the passage 8 in theend of the tube 7 and has formed on its outer end a milled head 14 by means of which the same is readily screwed into and out of the threaded passage 12 in the en barrel. In the outer end of the milled ead 14 is secured a rubber plug l5 which when the suction tube is in use for drawing ink into' the barrel is adapted to be inserted into the air passage 8, thus providing an air tight closure for the outer end of the suction tube. v

When it is desired to lill the pen, the threaded plug or in 13 is unscrewed 4rom the passage 12 an reversed so that the rubber plug 15 may be inserted in the air passage 8 of the suction tube. After the outer end of the suction tube has thus been closed, the point of the pen is inserted yin an ink well and the suction tube drawn outwardly thus` sucking ink up into the pen barrel.' After the desired quantity of ink has been thus sucked into the barrel, the plug 15 is removed from the air passage 8, thus o ening the outerend of the suction tube w 'ch will permit the latter to be closed or ushed back onto the pen barrel without orcing any ink therefrom, as the air in the suction tube which is displaced by the outer re, duced portion of the barrel, as the tube is closed, will pass out through the air passage 8 inthe end'of the tube. After the tube has thus beenI closed upon the pen barrel, the threaded plug or' pen is again inserted through the passage 8 in the tube and screwed into the threaded passage 12 in the end of the barrel. When the parts have and the minor details of construction may be resorted to Without departing from the principl or sacrificing an of the advantages of this invention as de ed in the appended claim. y A

Having thus described my invention, what I claim is A fountain pen comprising an ink barrel, a suction tube slidably mountedl on said barrel, said tube and barrel' having registering vent apertures, and a plug comprising a threaded shank adapted to pass through the aperture in the tube and thread into the aperture in the barrel to close the latter and lock the parts together, and a rubber stud 15 on the opposite end of the plug to enter and close the aperture in the tube independent of the aperture in the barrel.

In testimony whereof I have hereunto set my hand in presence of twov subscribing Wit- 20 nesses.
