To all whom t may concern:
Be it known that I, ROBERT S. OGILvr, a citizen of the United States, residing at Chica o, in the county of Cook and State of Il mois, have invented certain new and useful Improvements in Fountain-Pens; and I do hereby declare the foilowing to be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the aIt to which it appertains to make and use the same.
This invention relates to improvements in fountain pens, and more particularly to that type of fountain pen which is known as the self-lilling.
The invention has for its particular object first: to provide a fountain pen wherein the ink chamber is visible from the exterior of the pen to the .end that the user may know the extent of the supply at all times in .order that refilling thereof may be accomplished when necessary.
A further object of the invention is to prolvide novel and efficient means for effecting refilling of the pen by suction from an, inkwell or similar source of supply with ease and rapidi-ty.
A further object of the invention isto provide simple andV efficient manually operable means for effecting refilling of the pen when desired.
The invention consists in the features of construction and combinations of parts hereinafter fully described and particularly claimed. Y
In the accompanying drawings illustratin a suitable embodiment of the invention:
igure -1- is a view in side elevation of a fountain pen constructed in accordance with the invention.
Fig. 2- is a central vertical longitudinal section of the same.
Fig. 3 is a cross section on the line 3-3 of Fig. 2.
Fi -4 is a view similar to Fig. -2- showing a modified form of construction.
Referring now to said drawings, 1 indicates the barrel of the pen which' preferably consists of an outer casing of hard rubber or similar material or composition having preferably one or more longitudinal slots 2 therein. Where more than one of said slots is provided they are preferably diametrically opposed. They .ma be continuous or discontinuous as deslr Within the outer casing there 1s mounted a cylindrical shell 3 of a transparent material such as glass, Celluloid or any other suitable material. This may be mounted within the outer shell or casing in any suitable man ner to prevent the penetration or permeation of ink into the space between the same. The transparent shell 3 will provide a smooth cylindrical bore in which the piston 4 is reciprocable. Preferably the inner shell is of less length than the outer shell so as to provide a free space in the upper end of said outer shell. he said upper end of the inner shell 3 is closed by means of a plug 5 preferably of soft rubber having a central opening through which the piston rod 6 extends. The central opening of the lug 5 is bordered at its outer end by a flexible annular flange 7 which normally tightly hugs the piston rod 6. The opening is preferably sllghtly fiar-.ed at the inner face of the plu 5.
The lower end of the outer shelll terminates in what may be termed the pen section 8 which may be integral with theouter shell or suitably secured thereto. The section 8 has a central opening through which the feed element 9 of ordinary construction rojects, and into which the nib 10 is fitte in the usual manner. The feed element 9 projects partially into the inner casing 3.
The piston 4 is preferably made of soft rubber or similar fiexible material, and is provided with a central opening bordered by a valve seat on which the check valive 11 seats. The latter is free to move from seat a limited distance so as to pennittfluld to pass the piston 4 and enter the space above the same. When the piston 4 is at the lower limit of its movement the stem 12 of the valve 114 will rest upon the upper end of the section 9 thus maintaining said valve .open or oli its seat. At this time the plug 13 at the upper end of the piston rod 6 will project into the o n space above the plug 5. The outer shel is interiorly threaded to receive the external threads of the plug 13 whereb the ink chamber of the pen., as well as t e upper .end of the barrel, will be hcrmetically sealed.
In operation the flange 7 of the plug 5 acts as a check valve so that during movement of the plunger or piston 4 toward the plug 5 fluid trapped above the piston'4 will expand the dan e7 and will thus escape from the barrel. on a reverse or downward movement of tlie piston 4 the fiange 7 will so tightly lhug the piston rod 6 as to prethe vent air passing into the barrel thus creating a vacuum above the piston 4 which will permit fluid to pass into the chamber above the latter. During the first-named or upward stroke of the piston 4 the valve 11 will be seated thereby obviously creatin a partial vacuum in the s ace or chamber low said piston, and tius causing inkto be drawn up into the barrel. During the downward movement of the iston the ink drawn up into 4the lower ciamber above the section 8 will be held therein and will pass through the opening in the piston 4, as the latter moves into the body of ink, into the upper or ink chamber of the pen. As the downward move of the piston -l is completed and the plug 13 screwed into lace the valve 11 will be held ofi' its seat t us`permitting the inl: trapped above the piston to pass freely through the section 9 to the pen point to feed the latter.
In the construction shown in Fig. -4- the operation is slightly different in that the piston 14 carries a flexible cup washer 15 which normally hugs the surrounding wall of the inner casing. Thus, durin an upward movement of said piston llui trapped above the saine will be forced past the flange 16 corresponding to the flange 7 of Fig. but upon a downward movement of the piston air will be prevented from entering the barrel through the plug 5. During such downward movement air or fluid may pass the flan e of the cup washer 15 which acts exactly ike a. check valve, as will be obvious. The piston rod 17 is connected by means of a link 18 with the inner end of a rocking lever 19 which is pivotally mounted between its ends in a slot 20 in the outer shell abovethe upper end of the inner shell of the barrel. Communicating with the slot 20 is a longitudinal groove 21 in which the outer rojectin end of the lever 19 is adapted to e house when the same is not in use for reciprocating the piston.
In this construction it is not intendedgshat the ink sh'all pass the piston 14 into'llithe chamber above the latter. Accordingly Ilthe piston 14 is reci sary to draw in( into the barrel 'through the pen Section to any desired level which operato ascertains through the slot or slots 2. l en the outer proJecting end of the lever 19 is housed in the slot 2-1 the up .er end of the cup washer will press lig tly upon the inner face of the plug 5 thus preventing ink from passing the piston and thus findm its wa into the upper chamber of the linrrel. hen the lever 19 is in the position shown in dotted lines 1n Fig. 4, the inner end thereof will have passed the free end of the bowed spring 22 secured in the upper end of the barrel or casing 1 and the said spring will then serve to hold the lever in that position so that the out-er rocated as often as neces-.
Lamm' end Jortion thereof will lie in the groove 21 o the casing 1.
While I have shown the preferred einbodiments of' the invention in the accompanying drawings, it will be obvious that the same may bc changed and varied in details as mechanical skill may direct without departing from the invention as defined in the appended claims.
