animation aied'may 19, 1910. semi No. 562,2 a9j To all 'whom 'it may concer/rt:

Be it known that I, JOSEPH A. VOGEL- MANN, a citizen of the United States, resid-- ing at Brooklyn, in the county of Kings and State of `New York, have invented certain new vand useful Improvements in Self- Filling Fountain-Pens; and I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others 'skilled in the art to which it appert-ains to make and use the same.

This invention relates to improvementsV in self filling fountain pens.

The object of the invention is to provide an improved construction of fountain pen having means whereby ink may be readily drawn into the barrel of the pen land means whereby the` feed of the ink from the barrel is controlled.-

` With these and,V other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts as will 'be more fully deshown. The side 'engaged by scribed and particularly pointed out in the appended claim.

In the accompanying drawings: Figure 1 is a side view of a fountain pen constructed in accordance with my invention: Fig. 2 is a longitudinal sectional view of the same, and Fi-g. 3 is a vertical cross sect-ion on the line 3 3 of Fig. 2.

In the embodiment of the invention I provide a tubular barrel 1, the inner walls ofthe opposite ends of which are threaded as shownat 2. Arranged in the tubular barrel 1 is an ink holding tube 3l of rubber or similar elastic material. One end of thev tube 3 is secured in the outer end of the tube 1 by a plug 4 which is screwed into the threaded outer end of the barrel. The end of the tube is tightl clamped between the .threaded surfaces o the end of the barrel fluid tight.

extension 7 and the adjacent end of the 1 barrel is secured the inner endof the ink holding tube 3. By thus securing the opposite ends of the tube 3, said ends are made The ed nipple 6 is provided with a feed passage 8 Ain the'outer `end of which is sethe elastic ink receiving cient distance from its connected ends and' cured a pen-andv a suitable feeding 'device, as shown. In the inner end of the 8 is formed a valve seat 9v feed passage adapted to receive a plug valve 10 which is secured to the end of a valve stem 11. The Aopposite end cured to the plu 4 whereby when the latter is turned slight y in one direction or the other the valve 10 will be opened or closed as desired te regulate or stop the flow of ink to the feed passage in the nipple. Arranged in the barrel 1 on opposite sides of the ink tube 3are segmental compression plates 12 which preferably extend to near the closed ends of the tube. extend down and around the rubber tube as shown, and on said plates midway their ends, are formed outwardly projecting vlugs 13 which project through slots 14 formed in the opposite sides of the pen barrel as edges of the slots 14 are cut away to permit the lugs 13 to be readily the thumb and finger. As clearly shown the segmental plates are of sufficient length to be freely forced against tube 3 at a suiiiis separated from the barrel 1 by said plates. By means of the thumb and finger lugs 13 the plates 12 may be forced inwardly thereby compressing the ink tube which when'released '.vill again expand-and thereby draw ink up into itself, when the outer end ofthe nipple is inserted in the ink and the valve 10 opened.

From the foregoing description taken in connection with the accompanying drawings, the constructii n and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claim. f" Having thus described my invention, what I claim is:

In a 4fountain pen the combination of a barrel, the opposite ends of which are threaded, an elastic'ink-receiving tube arranged therein, a plug having a threaded engagement with one end of the barrel, a tubular feed nipple havinga threaded extension'adapted to be secured into the oppol The plates 12- siteend of. the barrel, the opposite ends of 'tact with the barrel and in perfect elne- 1o said tube'being secured -in position by the ment therewith. ping and nipple, segmental lates arranged In testimony whereof I have hereunto set on opposite sidesof the elastic tube, the ends my hand in presence of two subscribing 5 of which are located a suitable distance witnesses.
