'To all wwm z'tmay concern.'

Be it known that l, HENRY J. Urron, a citizen of the United States, residing at Somerville, in the county of -Middlesex and State of Massachusetts, have invented new and-useful Improvements in Fountain-Pens, of which the following is a specification.

My invention is an improved self-611mg fountain pen and consists in novel mecha,- nism and in vnovel organization of the parts by which the ink sack is collapsed.

ln the drawings Figure l is a longitudinal section of a; fountain pen embodying my invention;

Fig. 2 is a perspective view of the lever;

Fig. 3a is a side View of the lever;

Figs. 3" and 3 show cross sections of the lever on lines 3L-3b and fic-3c respectively of Fig. 2; Y

Fig. 4 is al detail of the presservbar and its holding plug, the plug being in section;

Fig. 5 is a plan View of Fig. 4;

Fig. 6 is a view of barrel showing the slot; and

Fig. 'i' is a cross section on line 7 7 of Fig. 6.

Self-filling pens in which the ink is contained in a soft rubber sack within the handle or barrel of the pen, and in which the filling of the pen with ink is accomplished by collapsing the sack and permitting it to expand bythe resiliency of its material, while the pen point to which it is hermetically secured is immersed in ink, are old .and Well known and various means and mechanism have been employed to collapse the ink sack. The object of my invenytion is to simplify the collapsing mechanism and cheapen the cost of manufacture and assembly.

To this end have devised an assembly of the presser bar, which is-in immediate contact with the ink sack, so that it is positioned and secured in place without the use of rivets, pins, or other positive securing means and have devised an organization by which the lever may be secured in place without pivot pins or the like.

ln the drawings l, is the barrel which is a cylinder open at both ends, 2 the point section, to the inner end of which is securedthesack 3. At the rear open end of the barrel 1, is fitted a cylindrical plug 4, which is attened upon one side to ireceive one end of the presser bar 5. The presser bar 5 is bent or hooked' at oneend and this angular portion 51 is inserted in a corresponding slot 41 in the plug Ll. lt will be obvious that when the presser bar is hooked into the plug and the plug inserted into the open rear end of the barrel the 'rcsser bar will be securely held in position etween the flat surface. of the plug and the inner surface of the barrel, as indicated inllig. l, so that it can neither be moved sidewise nor longitudinally. ln

' v inserting the presser bar the plug is turned etv so that the bar .is brought beneath the slot 11, where it is supported, longitudinally of the barrel, ldirectly beneath the slot and between the ink sack and the inner surface of the barrel.` Thepen section 2, with itsattached ink sack 3, having been insertedatl the end of the barrel opposite the plug 4, the lever 6, is next placed, the forked end being turned so that'its Width corresponds with the length of the slot. are pressed against the presser bar and .forced downward until the shank of the lever is Within the slot, when the lever is turned, leaving the forks', 66, straddling the presser bar and the broad `end of the lever Within thebarrel. lt will'be observed (see Fig. 3a) that the shank' ofthe lever is triangular in cross section and the broad end curved. When the lever is turned, it is in such fashion that the.. curved side of the forked portion and the oint of the triangular-shaped shank are ward the plug d. ylhe lever is then moved vto the end of the slot toward the lpoint section, the lever being retained in place by the upward pressure of the' presser bar and the engagement of the lforked portion with the inside of the barrel. proper position.

en the lever is moved to at the end of the slot the forks 66 are innmediately over a narrowed portion 55 oi the presser bar, the forks resting in two notches in the edge of the presser bar (see Fig 5). These notches .are so designed and positioned that when the shank of the lever is raised, to collapse the ink sack, the forks 66 will come into contact with the end'of the respective slots, thus stopping the lever in vertical position and preventing it from being by accident pushed too far. lt will be observed that when the lever is in an upright position, the forked portion depresses the presser bar, and that when the lever is thrown down the triangular shank lies in the tl-shaped slot 11, while the forked porf lilo lli

tion rests again@ the upper, inner surface of the barrel. ln either position the lever is retained in place by the resiliency of the ink sack and the resser bar, or either of them and performs its functions without being secured in place by Apins or otherl connecting means.

ln operatioumwhen the-lever 6 is lifted, it and the forks 66pivot upon the shoulders formed by the junction of the'broad portion 66 of the lever With the shank 6 of the lever, which shoulders coact with the inner surface of the barrel. 'lhe forks 66 swing in one direction upon these shoulders as a center While the shank 6 swings in the opposite direction, the inner end of the slot between the forks 66 pressing upon the presser bar and depressing it as the inner end of the slot swings about the center or ulcrum point formed by the engagement of the shoulders `with the inner surface of the barrel.

The outer surface of the barrel l, at the end in which plug 4 is mounted, is provided with a serevv` thread, with which a corresponding thread on the inner surface of sleeve 7 engages, so that, when sleeve 'l is rotated it is advanced or retracted on the barrel l and in this way, When it is desired te operate lever 6, the sleeve is retracted and the lever uncovered so that its tree end may be manipulated and the lever raised to collapse the sack, While, after this is accomplished and the lever is lying again in the slot l1, the sleeve 7 is advanced to cover the lever and lock it in 'position at the same time covering it. ln order that the free end of the lever may be easily seized, a

agencer rece l2 is formed upon the outer surface ot the barrel, which suciently exposes the free end of the lever to enable the lever to be easil grasped by the fingers. A cap 8 oil' usua term is employed to cover the pen the lever is lying in the slot. This arrangement serves as a stop to prevent the accidental forcing down of the shank of lever 6 with the possible ejection of inkirom the ink sack.

l claim:-

ln a fountain pen, the combination of a loose lever-having a narrow shank portion and a broader, forked end portion, the shank and forked end lying in dierent planes; a fountain or bolder, slotted to receive the shank of the lever; an ink sackwithin the holder; al presser bar mounted between the ink sack and the holder beneath the slotl and loose lever, and having .a narrowed portion beneath the slot to orm shoulders or stops upon the presser bar, the forked ends of the loose lever embracing the presser bar and fitting Within the recesses, and engaging with the shoulders when the lever is raised, all organized substantially as and for the purpose described.
