FUNTMN PEN.

RICHARD E. PERKINS, OF J'YOPLIN, MISSOURI.
FOUNTAIN-PEN.
resales@ To all whom t may concern.'
' Be it known that I, RICHARD E. PERKINS, a citizen of the United States, residing atv Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Fountain-Pens, of
which the following is a specification, refy erence being had to the accompanying drawings. This invention relates to certain improvements in fountain pens, and it is an object of the invention to provide a device of this generalgcharacter with novel and improved means whereby thenib or pen point may be moved or adjusted longitudinally of the feed bar to regulate Vor control theflow of the lnk. 1
Another object ofthe invention is to pro-4 vide a novel and improved fountain pen wherein the writing end portion of the 'barlrel has engaged therewith a rotatable member operatively engaged with the nib or pen point whereby the pen point or nib may be moved longitudinally with respect to the feed bar and independently thereof so that the fiow of ink may be stopped or the pen point or nib beso positionedto geta heavyV flow of ink or a light flow of ink or any intermediate degree of iow to suit the individual user or the character of writingdesired.
The invention consistsV in the details v of construction and in the combination and arrangement of the severalv parts of my imf proved fountain pen whereby certain im; portant advantages are attained 'and the device rendered simpler, less expensive and otherwisev more convenienti and advantageous for use, as will'be hereinafter more fully set forth.V f Y The novel features of my invention'will hereinafter be definitely claimed. Y.
In vorder that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:
Figure 1 is a view partly'in longitudinal section and partly in elevation, illustrating a fountain :pen constructed in accordance with an embodiment of my invention;
Fig. 2 is an enlarged fragmentary view inV section of the writing end portion of a foun-V tainV pen illustrating my improvement-s in `v detail; land Fig. 3 is a fragmentary view in top plan of the pen point or nib 'as herein embodied.
afi-ENTIOFFICW Specification of Letters Patent. Patented Feb, 22, 1921.v Application led February 21, 1920. Serial No. 360,297. `v
As disclosed in vthe accompanying 'drawings, B denotes a barrel, preferablyk con-y structed in accordance witlifthe embodiment of my invention as particularly disclosedin my co-pending application, VSerial No. 352,381, and which has extending inthe writing end portion thereofI a feed` bar F.
The'feedbar F is of substantially the sameV construction as Vembodied in lmyV co=pending application, Serial No. 352,382, and "which feed bar F isgp'rovide'd in its forward end* portion with a pocket or recess 7"'servingfas a trap to retard the flow of the writingfluidV and alsol serving as a reservoir to'hold a surp lusof writing fluid inV orderthat the delivery' of the fluid through the nib vor penv point N can be materially facilitated. lThe A .recess'or pocket '7 isfalso" in suitable communication with the'conduit l 'extending longitudinally of` the "feed bar F and through which vthe writing fluid within the' barrel B or more particularly the tubular member or reservoir 5 Hows tothe pocketor recess 7. The maj or portion of the lfee'd'bar F from its writing end to a point in 'clos'e'- .proximity to its opposite end is ofl reduced thickness and whereby is 'provided the shoulder or stop 2; VThe kportion of the feed `bar F in Vadvance or-forwardly of the stop or shoulder 2 constitutes the working face e of the feed bar vand said working face is substantially convex in cross section.l Thejnib or point N isfsubstantially concavo-convex,
in cross section with the radius of the con-- cave face thereof substantially thesame Yas the radius of the convex working face of the feed barvF so that whenv the nib or point N'is in applied or working position, the concave face of the feed bar F will have substantially close contact with the working or concave face of the nib or point N with the Y inner end; portion of the split or opening a in the writing end of the nib or. point overlying the pocket orrecess 7.
When the pen is not infuse, the applic nib or pointN is adapted to Vclose the pocket or Avrecess. 7' andV which is accomplished bv moving' the `nibror point N longitudinally ofl the feedbar to position the inner end of the split orl'opening aeitlierin advance of or rearwardly of thepoc'ket lorrecess 7 During a writing operation, however, the
openinga or the inner end of the split of the nib or point N is adapted to overlie or Vpartially overlie they pocket or recess 7 whereby the requisite flow of the writing fluid to the writing end of the nib or point N is permitted as the resultant flexure of said end portion of the nib or pen causestlie same to move away or separate from the working face of the feed bar. The quantityV or amount of such flow is dependent upon the extent to which the inner end portion v,of the split or opening a of the nib 'or point the sleeve or nipple 8 and the opening 6 withy N overlies the pocket or recess 7. The more the inner end portion of the split or opening a overlies the pocket 7, the greater the flow of the writing fluid and vice versa.
Threaded upon the writing end portion of the barrel B is a sleeve or cap?)` which, upon requisiterotation, moves either outwardly or inwardly with respect to the barrel-B'. The outer end. portion of the sleeve or cap .Bis provided with the head ll,V having.
the central opening 6 land whichv openingl is defined` bythe outstandingnipple or sleeve 8. TheY writing end portion of the feed bar Fand the'nib or point N is disposed through the nib or point N snugly engaged between `the working face of the bar F and the adjacent linner wall of the nipple or sleeve 8.
'llhe nipple or sleeve 8, at a predetermined point intermediate its ends, is provided with the interior annular groove or channel 9 in which snugly engages a transversely disposed outstanding/bead 10 carried by the nib or'point N and which bead or rib is preferably pressed out from said point or nib. 1As the sleeve or cap 3 is rotated, the
' nib or point N will be moved inwardly or outwardly with respect to the feed bar F y in accordance with the direction of rotation of the sleeve or cap 3 so that effective means are provided whereby the nib or point Ny may be moved or adjusted to regulate or control lthe flow of the writing fluid. The inner end of the nib or point N contacts with the shoulder 2 of the feed bar F to limit theV inward movement of the nib or point N with respect to said feed bar F and when at the limit of such movement, the inner end of the'split or opening a is positioned inwardly of the pocket or recess 7 lwith the split of the point or nib N extending across the pocket or recess 7 so that the flow-of the writing-fluidis slight. This same result will occur in the event the nib or point N is moved outwardly to position the inner end of the split or opening a entirely in advance of said recess or pocket 7.
1V also indit of advantage to provide the inner wall of the barrel B adjacent its writing end with the interior recess or groove 12 extending,longitudinally` thereofand in which is positionedV a spring 14, preferably of a bow type and which engages the adjacent portion of the nib or point N to maintain said point or nib N pressed close to the adjacent or working face ofthe feed bar F to prevent leakage of the writing fluid betweenrthe inner face of the nib or point N and the adjacent working face of the feed bar F.
From the foregoing description, it is thought tobe obvious that a fountain vpen constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated,l
and it will also be obvious that my invention is susceptible of some change and modification without departing from the'principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement andrformation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
1. A fountain pencomprising in combination, a barrel, a feed bar extending within said barrel, a face of the feed bar being Y provided with a pocket, said feed bar being l provided with a delivering'conduit leading to the pocket, a 'nib normally in contact with the working face of the feed bar andy eX- tending within the barrel, and means for adjusting the nib independently of thev feed bar to control the inner end portion of the l split of the nib with respect to theipocket'.
