To all whom t may concern:
Be it known that I,.EDw1N F. BRrr'rEN, J r., a citizen of the United States, and a resident of Jersey City, inA the county of Hudson and State of New Jersey, have invented a new and Improved-Spring and Presser- Bar for Fountain-Pens, of which the following is a full, clear, and exactl description.
This invention relates to fountain pens of that type in which the writing fluid is contained in a sack in the barrel of. the pen, and the invention has to deal more particularly with the sack presser bar and return spying therefor. Y
' The invention has for its generalobjects to improve and simplify the construction of presser bars and springs for fountain pens so as to be-reliable and efficient in use, comparatively simple and inexpensive .to manufacture, and so designed that the spring and presser bar can be easily and quickly connected.
' A more specific object .of the invention is the provision of novel connecting means between the forward extremity of the' return spring "and the intermediate portion of the presser bar, the connection being pivotal, does not interfere with the presser bar being uniformly pressed against any sack at all points, and furthermore, the spring and presser bar have detachably connected interloc ring -parts so that the riveting ofthe spring and bar with the attendant disadvantages are overcome.
With such objects i`nview, and others which will appear' as the des-criptionfproceeds, 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 longitudinal section of a fountain pen with the presser bar and its return spring in normal position; Fig. 2 is a similar view showin the presser bar completely depressed; an Fig. 3 is a plan view 'of the presser bar and spring before 'the same areconnected. I
Referring to the drawing, 1 designates the barrel of a fountain pen, which barrel houses an ink-containing resilient sack' 2- Specification 'of Letters Patent.

that is adapted to be compressed by a presser bar 3 which extends substantially the length of the sack, such presser bar being depressed in any suitable manner, as, for instance, by a lever 4 fulcrumed at 5 in a longitudinal slot 6 provided in the4 barrel of the pen. When the lever 4 is restored to normal position, `as shown in Fig. 1, from the posi-tion 7shown in Fig. 2,- the presser bar is restored by means of the return spring the. butt end of the barrel. The forward or 'free end ofthe spring is formed into a T- shaped hinge element 8 whichwis adapted to enter an obliquely disposed slot 9 in the presser bar 3. This slot 9 is long enough tfo= accommodate the lateraily projecting' lugs 10, and the intermediateportion of l,the slot is enlarged at'll into a rectangular opening to receive the tongue 12 of the extremity 8. This extremity 8 is slightly offset from the straight portion of the spring l7, and the presser .bar is raised at the slot so as to accommodate the extension 8 which `lies within thehollow formed on the under side of thepresser bar by the said raised portion. The presser bar is provided with a channel 13 on its upper side so that the flat portion of the spring will lie in the plane of the latter is in-normal position. lIn connecting the parts the spring is held approximately at right-angles to the and with the fiat faces of the straight portion'of the spring at an angle to the length o-f the presser bar, so that the extremity 8 of the spring can be entered inA the slot 9. After the extremity 8 is entered 'the spring is turned so that the lugs 1() will be disposed transversely to the slot 9. Vhen the spring and presser lbar are inserted in a barrel they can never assume a position wherebythey can be accidentally disconnected. This joint between the presser bar is' pivotal', and as a consequence the presser bar can be pressed te the same extent at each endwhen the lever al. is operated, which is not the case when the spring Vand presser bar are riveted together, as the spring tends to hold the rear portion of the' presser' bar raised..
F roln the ferev'oing description taken in to be the best embodiment thereoI desire to have it understood that the device shown is merely illustrative and that such changes. may be made when desired as fall Within the scope ofthe appended claims. 4. t
.Having thus described vmy mvention, I
claim as new and desire to secure by Letters.
Patent:
1. A fountain pen comprising a barrel, an
ink-containing sack therein, a presser bar l. 'element for the sack, a returnspring ele-- 'fment for the presser bar, and a. pivotal conment and a slot inthe other. element` in` v name to this specification in the presence of nection between the said elements, said connection comprislng a memberon one e1e` which 4the member interloeks.
2; A fountain pen including a barrel, an
inhmontaining sack in the' barrel, a presser bar. for ,compressing the' slack, and a return' sprlng for the presser bar, said return spring including a T-shaped extremity, and
copies of this patent may be obtained for thepresser bar ,having means With Which 'bar having intermediate its ends a 'slot disposed obliquelyrto the length of the bar, and a spring having a T-shaped extremity engaged in the slot to pivotally connect the barand spring. 4. A presser bar for a fountain pen, and a return spring havingits extremity detachably .and pivotally connected with the presser bar at a point intermediate theends of the latter.
In testimonv whereof I have signed my two subscribing witnesses.
