VATENT C. WAHL AND ALBERT H. STEN'ERSEN; OF CHICAGO, ILLTNOIS, ASSIGNORS TO THE i COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE FOUNTAIIN-PEN-FILLI'NIG DEVICE Application filed October 24, 1925. serial m. 64,485.

Our invention relates to a device which may be readily applied to an ink bottle or the like for facilitating the filling of a fountain pen, and among the objects of our invention are the following:

To provide a device for aiding in the fillingi of fountainpens. v p

0 supply a device-whereby the ink in the bottom 0 a bottle may be conveniently used for the filling of a fountain pen. 1

To supply a device whereby a fountain pen may be more quickly and efiiciently filled.

To provide a.device whereby the pen point of a fountain pen may be protected from injury by contact with the hard glass or other material of a bottle.

' Another object of our invention is to provide a device containing a cup .of suflicient depth which is normally filled with ink so that when the penis introduced the filling is accelerated.

A. further object is to provide a device easily attached to a bottle and available for immediate use in aiding the filling of a fountain pen, and. such further objects, advan-.

tages and capabilities as will later more fully appear.

Our invention further resides in the combination, construction and arrangement of parts shown in the accompanying drawings,.and'

while we have shown therein a preferred embodiment we wish it understood that the same i is susceptible of modification and change without departing from the spirit of our invention.

Referring to the drawings- .body member 10, having formed therein and extendin from the lower side thereof an axially 'sposed depending hollow cup 11 forming the well 13. The body member 10 is formed with a mouth 12 continuous with thewalls of the well 13 for the reception of I a fountain pen. I The exterior of the cup 11 is formed with a groove 14 for the reception of a tube 15, which extends through an opening in boss 16 into communication with passageway '17 leading into the upper portion of.

well 13. -When the tube 15 is placed in the groove 14 and inserted into theopening in boss 16 a passageway for the flow of ink or the like is created, reaching from the-end of tube 15 to the interior of the well 13.. An air passage 18 extends through the body member as plainly shown in Figspl and 2, to prevent the creation of a partial vacuum within the bottle above the ink level. The ,body mem-. ber 10 may be formed of rubber or other suitable material.

In operation the body member 10 with the tube 15 attached as shown is inserted into the neck of the bottle (see Fig. 1). A fountain.

pen point 21 is then introduced into the mouth" of the body member, the lower circumferential edge of the pen section upon the application of a little pressure forming an airtight connection with the walls of the body member mouth 12. Before introductionlofthe" .pen point into the mouth 12 the self-filling arm 22 of the fountain pen should be moved to open position to expel any ink and air that may be in the'barrel of the. pen. After in-. troduction of the pen in mouth 12 the self-fill ing arm 22 ofthe fountain pen is closed and a suction is thereby caused by the return of the compressed ink sackto normal position which causes the .ink to flow upwardly through the tube 15 into the interior of the well 13, and through the ink feeding chan- Fig. 1 is a vertical section through an ink.

nels into the ink sack of the pen.

After a certain amount of suction the ink not used by the pen remains in the well so that upon the next operation the filling is more immediate than the first filling. In this dway a normal immediate filling-is .assure The air hole l8 acts to replenishiithe air in the inkhottle and'tli-us prevents a' vacuum v 'or partial vacuum within the bottle "jabove the ink. In this way constant and positive tSllCtjOD. upon operation of the filling "arm 1 22 is insured.

It will readily be seen that the tube 15 extends to the remote depths of the ink bottle 20, and thus insures that the ink will be available for use substantially to the bottom of the bottle. When filling a pen in the old way, without our device, it is necessary to have a substantial amount of ink in the bottle to bring the level of the ink sufficientlv high for filling purposes. Our device preferably, having a soft mouth also pre 19 vents any danger of the pen'being injured by contact with roughor hard surfaces.

Having now described our invention, we claim Y 1. In a fountain pen filling device, the combination with an ink bottle of a body membpr fitting and normally fixed within the mouth of said bottle and provided with a vent, a depending well and'a mouth leading through the top of the body to the well, sai mouth being so formed as to permit a tig t engagement of the shoulder-of a fountain pen therewith below said vent, and a depending feed tube having its upper end communicating with said well at a position" above the bottom thereof so as not to drain the well when the device is not in use.

2. A fountain pen filling device comprising a body rovided with an ink-retaining well extending downwardly from the top face thereof, said body also having an open vent therein adjacent to but separated from said well, and a feed tube having a discharge end communicating with said 'well, the inlet end of said tube being located at a lower level, a portion of said well being shaped to make a tight fit with a fountain pen so that ink will be drawn through the feedtube into the well and from the well into the pen solely by the operation of the self-filling'mechanism of the pen, the discharge end of said tube being positioned above the bottom of the well, so that a residual body of ink will be retained in the well after each pen-filling operation. p
