- Application led Jar'umryy 27, 1905.l Serial Nn '242,858-

To a/Zllwhorvn, it may cncerm Be it known that I, JAMES SINNOTT, a citizen of the United States, residing atChatl ham, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Fountain-Pens, of4 vwhich the following is such a ull,.clear, and

I exact descriptionas will'enableothers skilled in the art to which it appertainsto make and use -my said invention.V y My invention relatesto pens which have van ink-reservoir in the pen-handle.y

. ,f The purposes of lmy invention are to promunicating with ythe ink-reservoir in the,

vide, in connection.. with a holder having an ink-reservoir, a pen of nnproved construction having an mclosed lnk-chamber comv holder; to provide means for controlling the fine line, such as is commonly used inwriting,

a fine line `and a somewhat heavier line ad'a-l f cent thereto, such as is commonly used y bookkeepersin ruling at the foot of columns vwhen accounts are `balanced or closed, and a ine line and a relativel wide line, such as is commonly-used by dra men for the border linelofmaps or t e like. By lreason of the diversit of linesdescribed the pen is also very e ective in ornamental lettering or With these ends in view my invention consists in the novel features of construction and combinatlons of parts shown in the annexed drawings, to which reference is hereby made and in which similar referenceletters desig-v natelike parts in the several views.

Referrin to the drawings, Figure 1 is an lelevationo thefountain-pen com lete. Fig.. 2 is an axial section through the older and shows the pen in position 1n the holder, the convex upper sideof the pen being visible.

Fig. 3'is a plan of the en detached looking at the concave under si e of the pen. Fig. 4 is an enlarged combined side elevation and sec? v tional view of the pen-socket and the pen in position in the socket. 'Fig 5 is a greatlyenlarged transverse section through 'thepen on the lin'e 5 5 of Fig. 2. 6 is an enlarged'transverse section on the line 6 V6 of point. y

against the plate b', so as to hold the plates Fig. 4. Fig. 7 ist. plan. of the tongue detached. f

The holder A is preferably a hard-rubber v tube; but other non-corrodible material may be used. A capA iits on. the handle and incloses the pen .when not in use; When in use, the cap fits on the up er end of the holder in the usual manner. The pen-socket A2 screws -into the lower end of the handle -and has an interiorchamber a* communicating with theV reservoira2.

The lower part, of the Isocket 'is' Y curved, as at a, Figs. 4 and 6, to fit snu 1y around the shank o he pen, and the pen ts in and closes the opening in the lower end or'l the en-socket A2. The intermediate-part a/ of t e member A2 gradually contracts and convergestoward the part a., andthe conver ing part of the member A2 forms a duct or c annel a3, leading the ink from the reservoir a in the holder into the ink-chamber b3 in'tle pen.

The en B consistsof two concavofconvex plates and bLtapering and converging to a Ears b2 on the vplate -b turn back.

together. e The inner plate bis' somewhat less concave vthan the outer plate b, andthe space between-the plates forms a Achamber b3,

adapted to cdntain ink. In the inner plate b is an elongated opening b4, through which ink is'admitted into the chamber. The pen is closed at its upper end, as'shown in Fig. 4, so that ink cannot pass directly, into the chamber through 4 the end of the pen, but must be admitted through the opening b5 in the under side of the pen.

When the pen is in the socket Athe open i ing b4 is in line with the duct and the uan-l tity of ink flowing from the Vduct throug the ope b* into the chamber b3 of the en may be varied at pleasure merely by sli ing the pen upward o r downward in the socket,.so as to increase or diminish the'extent of' the open'- thereby correspondingly increasing or the ow'of This feature is of great practiealadvantage, because if the ink flows too fast the pen may be slid outwardly to diminish the flow, and if it Hows crease the flow.

-non-corrodib'le metal rial. l

In the central part of the late b is a longi tudinal depression b5, whic serves to retain ordgther suitable matethe tongue D in the pen, as hereinafter ex too slow the pen may be pushed inward to in-d The pen may be made. of hardrubber or l 'IIO i plates b -andvb of the pen and is held in place therein by the metal of the plate b ressed inward to formthe .depression b5. he tongue is kept in place by friction with sufficient firmness to avoid accidental displacement of -the tonguefbut permitting the tongue to be slid inward .or outward to adjust the nibs to suit the convenience of the user. ture is of greatpractical advantage, because it admits of the use of a minimum quantity of gold or other precious metal in the construction without impairing the effectiveness of the en. .Y

o the edges of the pen B at its lower end an adjacent to the tongue D arev slits b6 and b?. the lower endsl of the slits are at different distances from/theaxis of the tongue, so that when the en is turned ed ewise for the purpose of ru as hereina ter described, the

onger slit b? will make a wider mark than wouldvbe made by the shorter slit b8 on the The inclination of the slits to o posite side. -t e axis of the tongue D is such that if either' edge of the pen be placed in contact with the paper the entire le th of the slit in that edge will contact wit the paper. In writing the oint of the pen is aced on the pathe en is used in t e usual manner.
