GEORGE T. BYERS, OF NYACK, NEW YORK.
FOUNTAIN-PEN'.
To all 'whom it may concern:
Be it known that I, GEORGE T. BYERs, a citizen of the United States, and a resident of Nyack, in the county of Rockland and State of New York, have invented anew and Improved Fountain-Pen, of which the following is a full, clear, and exact description.
This invention relates to fountain pens of that type including an ink-containing sack, and the invention has to deal particularly with the means for deflating the sack when it is desired to charge the same with ink.
The invention has for its general objects to improve and simplify the construction and operation of devices of this characterso as to be reliable and efcient in use, comparatively simple and inexpensive to manufacture, and so designed that the presser bar can be actuated by a slide movably mounted in a slot in the barrel of the pen.
A more specific object of the invention is the provision of a combined spring` and presser bar of such design that by a slight movement of the slide the presser bar will be actuated to deiate the sack, there being novel means for mounting the presser bar and slide in the barrel of the fountain pen, so that the parts in assembled condition can be inserted in the open end of the barrel and properly positioned with despatch and the least amount of trouble.
With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.
In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,
Figure 1 is a central longitudinal section showing the parts in normal condition;
Fig. 2 is a similar view, showing the ink sack deflated; A
Fig. 3 is a transverse section on the line 3 3, Fig. l;
Fig. 4: is a perspective view of the combined spring and presser bar; and
Fig. 5 is a side view of the presser bar operating slide.
Referring to the drawing, 1 designates Specification of Letters Patent.
Serial N0. 335,109.
an ordinary barrel of a fountain pen in which is the usual ink-containing sack or reservoir 2. The barrel 1 is provided with a longitudinal slot 3 in which is disposed the operating slide 4 that depresses the presser bar 5 so as to deflate the sack. As shown in Fig. 5, the slide 4: has a bar-like portion 6 lying within the barrel and a serrated portion 7 lying within the slot 8. The presser bar is a strip of spring metal which has resilient extremities 8, and the portion 9 between the extremities is rendered less flexible by being transversely arched, as clearly shown in Fig. 3. By this means the presser bar can have its ends confined in a given plane, and the arched portion can be moved outl ofthe plane because of the bending taking place at the flattened extremities 8. Thus, by depressing the presser bar the arched portion thereof can compress the ink-containing sack throughout the entire length of such straight or stifl'ened portion of the presser bar, as shown in Fig. 2. presser bar is connected at 10 with the upper extremity of the bar 6 ofthe slide, and the other extremity of the presser bar is connected at 11 to a longitudinally split sleeve 12 slidably tted in the barrel and surrounding the ink sack. The slide 4 is held by means of a sleeve 13 which has a longitudinal slot, they edges 14 of which engage in lateral grooves l5 in the slide 4. This permits the slide to move longitu dinally but prevents the slide from being pressed inwardly. When the parts are in normal position, as shown in Fig. 1, the presser bar lies in engagement with the slide 4, and by moving the latter from one end of the slot 3 to the other the slide causes the presser bar to become flexed, as shown in Fig. 2, so that the air will be forced out of the ink sack. The fountain pen is now dipped in a bottle of ink, and when the pressure is removed from the slide the presser bar will return to normal position, so that the expansion of the ink sack will draw in a charge of ink. It will be noted that the parts which form the sack-deflating means are so designed that they can be assembled to form a unitary device which is easily and quickly placed in position without the need of any fastenings.
From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and One extremity of the PatentedDec, 16, 1919.

method of operation will be readily understood by those skilled in the art to which the invention appertains, and While I have described the principle of operation, together with the article Which I noW consider to be the best embodiment thereof, I desire to have it understood that the article shown is merely illustrative and that such changes may be made when desired as fall Within the scope of the appended claims.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
l. A fountain pen including a barrel having a longitudinal slot, an ink-contain ing sac-l; in the barrel, a presser bar having spring ends, said bar being of uniform thickness throughout its length and having its intermediate portion curved transversely, a slide disposed in the barrel and connected With one end of the presser bar and having a gripping portion disposed in the slot, and fixed means in the barrel for holding stationary the other end of the presser bar.
2. A fountain pen comprising a barrel, an ink-containing sack therein, a presser bar being more yielding at its ends than at its intermediate portion, said bar being of uniform thickness throughout its length and having its intermediate portion curved transversely, means for holding stationary one end of the presser bar, and means for actuating the other end of the presser bar to cause the unyielding portion to move transversely of the barrel to compress the sack.
3. A fountain pen including a barrel having a slot, a sleeve in the barrel having a slot coinciding with the slot of the barrel, a slide having grooves in its side to receive the edges of the slot in the sleeve, an ink sack in the barrel, and means operated by the slide for depressing the ink sack.
4:. A fountain pen including a barrel having a slot, a sleeve in the barrel having a slot coinciding With the slot of the barrel, a Slide having grooves in its side to receive the edges of the slot in the sleeve, an ink sack in the barrel, a second sleeve in the barrel, and a combined spring and presser bar having one end connected with the slide and the other end With the second-mentioned sleeve.
5. A fountain pen including a barrel having a slot, a sleeve in the barrel having a slot coinciding with the slot of the barrel, a slide having grooves in its side to receive the edges of the slot in the sleeve, an ink sack in the barrel, a second sleeve in the barrel. and a combined spring and presser bar having one end connected with the slide and the other end With the second-mentioned sleeve, said combined spring and presser bar being in the form of a strip oi' spring metal fiat and resilient at its ends and transversely arched intermediate its ends. i
i 6. A fountain pen sack deflating means comprising a pair of spaced sleeves adapted to frictionally fit in a fountain pen barrel, a presser bar connected With one sleeve and extending through the other sleeve, and slide connected with the free end of the presser bar and slidably mounted on the sleeve through which the presser bar eX- tends.
7. A fountain pen sack deflating device comprising a pair of split sleeves adapted to fit in the bore of a fountain pen barrel, a presser bar having one end extending into one sleeve and movably connected therewith and extending entirely through the second sleeve, and a slide movably mounted on the second sleeve and hingedly connected with the presser bar.
