DEVICE FOR FILLING FOUNTAIN-PENS.

Lacasse.

To all 'whom t may concern:

Be it known that I, Panna P. FLoUnNoY, a citizen ofthe United States, residingat Bethesda, in` the county", of Montgomery and State of Maryland, have invented certain new and useful improvements in Devices for Fil." 1g Fountain-Pens, of which the followingis a specification.

My invention relates to means which may be vquickly and easly'applied 'to all the eX- isting forms. of fountain pens, and lill or replenish the writing"a `fluid within the barrel of the pen. e

The objects of my invention are for the purpose of forming a device of the character abovev indicated, and isintended to form a means by which a fountain pen reservoir may be filled without unscrewing and sepa'- i rating-'the feeding attachment in which the pen point is'fastened from' the ink reservoir or barrel of the pen, and also without removing the pen point from the feeder or reversing the ink'stand ,or other container from which the ink is to be withdrawn and forced into the barrel or reservoir of the fountain pen.

The invention consists of structural characteristics and relative a-rran ements of elements which will be Vhereina ter more fully. described and particularlyv pointed out in the appended claims.

' In the one sheet of 'drawing in which similar reference characters indicate the same parts in the several figures: f

Figure 1 is a side elevation of the device embracing my invention;

Fig. 2, is a longitudinal vertical section of the device applied 4to theneck of an ink container and showing in elevation the relation of a fountain penpoint when used in conneet-ion with the device, and

Fig. 3 Vis a section on line lll-fill of Fig. 2.

Referring to the drawings a is a hollow compressible rubber bulb which is provided with an extension or mouth piece D. also of rubber and provided with outwardly tapered conical or fil-ring opening receive point end of a fountain pen, as shown in Fig. 2. The inner walls of the cavity within the bulb c and nest to the opening Z1 are flared outwardly for the4 purpose of preventing the pen point of the peut?, see Fig. 2 from coming in contact with tl interior ii il 7) adapted to tightly and firmly the usual conical end of the pen` ofthe bulb a, and hence giving no chanceffor said pen point C thus to .become injured.

y Attached to and preferably` integrally formed with the bulbe is it base section or stopper al which isadapted toy lit snugly and tightly within the neck of abottlela erany Speciiication-of Letters Patent.V Ptgned Jan, 2'9 1919. Application filed October 22. 1917. Serial No. 197,770. l l

container for ink, as showiifiii Fig. 2, and is provided with a-fiange k capable oflf'nrmly seating itself on the top of themouth'` of said bottle B. Depending from and connected with the outer or lower end ofthe base section or stopper c5 is a, tube e which cornniuni -cates by means of a passage c` within-the stopper al, with the interior ofthe bulb a, and the lower end g of said tube e, is cut 0E diagonally, as shown for thepurpose of 1permittin bothink and air toy flow freely -througrli said .tube e, and passage ef when the bulb c is manipulated in lillingv'the fountain pen to be hereinafter described. r'Said bulb c is arranged in order to bring-.the axis of its hollow interiorv in such .a position and in a plane substantially norxnalft'o the axis of the internal passage e', sothat theinlr iremaining in the bulb after the penv has'bcen filled, as will bepresently described, will gravitate or liow back into the b'ottleB. '0n

the outer side and near its upper` endy of the base section or stopper al which is adapted to fit within the neck of the bottle or container B is formed an encircling annular 'recess c', and a series of separated trenchesordepressions f, f, extending from the said recess a' to the lower or tube end of the stopper d, for

the purposes to be .presently described. A

The operation of the invention isas follows: V

The pen 'peint C having been securely and tightly fastened into the flaring opening b", as shown in Fig. 2, the stopper al is raised out of the opening in the neck of the ink container or bottle B, until the annular recess i isin communication with the outside air.

if the bulb a is now compressed, a portionof the air in it is forced through the passage e and tube e, down through the ink in the container B, andemerges from the ink, an equal amount of air escaping by way of the depressions f, f, and recess ci, to the atmosphere. 'l/Yhenthe bulb a is released from pressure and Aallowed to expand, some of the air within the hollow en barrel is drawn out, and some of the inl; bottle B is drawn up to lill the vacuum formed in thebulb a by its ex ansion. This operation of compressing ana releasir'r the in the container or bulb a is repeated, drawing up more ink and expelling more air from the pen barrel, and the pen point C being slightly depressed below the horizontal position, the ink Will pass down into the pen barrel to iill the increasingly perfect Vacuum therein, While the air being lighter than the ink rises and passes into the hollow bulb a, and is eventually by repeated compressing and releasing of the bulb, forced asy previouslyl explained through the passage e and tube e and up through the ink, and finally escapes into the atmosphere by the vents or depressions f, f, and recess z', until the ypen barrel is entirely filled with ink, and the gurgling sound produced by the passage of the outgoing air through the ink ceases, indicating that the filling of the pen is completed. After this operation and after the withdrawal of the pen from the mouth piece 6, the pen is ready for use.

The object of providing an annular recess c', with a series of depressions f', is for the purpose of sub dividing and distributing the outgoing air` entirely aroundthe stopper d and prevent any great air pressure at any one depression or vent f, which would tend to squirt or force out suddenly any ink which might lodge or collect, if a single (lepression f were employed. The recess 'e'. extends entirely around the stopper and of a depth as shown for the purpose of acting as a reservoir to receive any ink which might be forced through the depressions or vents f, thereby preventing any ink. from being thrown out from the stopper or bottle during the compression of -bulb Z; and filling of the pen barrel A.

From the foregoing disclosure of the construction and operation of the device, it will be seen that all of the advantages and functions set up in the statementV of invention are fully carried out, and it will also be understood that many modifications will readily suggest themselves Without departing from the spirit and essential features of my improvements.

What I claim is: l. A device for filling fountain pens cornprising a base section provided with external.

having its interior in communication with' the open end of the internal passage opposite to that which is in communication With said tube and provided with an extension having an opening adapted to snugly and tightly receive the pen point end of va fountain pen.

2. A device for filling fountain pens comprising a base section provided with a single external annular recess and `a series of trenches normal to and connnunicating with said recess and having an internal passage a tube haring its upper end attached to said base. and communicating with one end of said internal passage and its lower end adapted to pass below the surface of the writing iiuid, a' hollow conipressible bulb secured to said basesection having its interior in communication with the open end of the internal passage opposite. to that which is in communication `with said tubeand provided with an extension havingan opening adapted to snugly and tightly receive the. pen point end of a fountain en.
