FOUNTAIN-PEN FILLER.

Specifieation of Letters Patent.

Patented Ma 19, 190s.

i M, s A licant filed may 23, 1907-. 5 Serial No. 375,289.

To all whom it may concern:

Be it known that I, ILQQITDJKNATHANIEL CARPENTER, a citizen of the United States, and a resident of New York, in the county of New York and State of New'York, have invented certain new and useful Improvements in Fountain-Pen Fillers, of which the following is a specification.

This invention relates to a device for filling [fountain pens and the like and its novelty consists in the constructionand adaptation of the parts. i

The object of the inventionis quickly to fill a pen in a clean and simple manner without danger of soiling the fingers and without any need of removing the point of the pen from its barrel.

In the drawings, Figure 1 isa vertical central section through a form of the device embodying my invention and Fig. 2 is a plan view thereof; Fig. 3 is a vertical central section through a modified form of the device embodying my invention and Fig. 4 is aplan In Figs. 1 and 2, 10 is an ink reservoin made of any sultable size and material and represented partially filled with ink. It is restricted at its to to form a neck which is externally threaded.

11 is a closure for the reservoir in the form of a compressible bulb, reierably made of soft rubber, or similar e astic material, terminating at its bottom in an external flange adapted to fit over the upper edge of the reservoir neck and which is held in place by a threaded rin 13. The bulb 11 is provided at its top with anaperture or mouth'14 preferably but not necessarily made with an inward ta er. The purpose of making the closure 0 thereservoir 1n the form of a compressible bulb is to enable the user to vary the pressure of theair the reservoir by squeezing the bulb and alldeving it to expand; and the urpose of the tapered aperture is to permitt e oint of the pen In to be inserted therein an to form an air tight joint therewith, even when it is used with pen points of difierent sizes and shapes. When the device is not in use the mouth 14 is closed with a cork, or in any other suitable manner.

In usin the device, the pen is inserted in the mout 14, point downward, until it firmly seats against the walls of the aperture and the device is then inverted or turned over until the level of the ink therein is above the. device is turned the opening'into the pen point. The bulb 11 is then compressed. .Such compression increases the pressure of the air w thin the reservoir and forces a quantity of the ink pen barrel} The pressure upon the bulb is then relievedthrough the pen point into-the and a small quantity of air is -'thus' expelled from he pen. The bulb is again compressed and allowedto expand and the operation is repeated until the pen has been filled. The device is then again placed in an upright position, the pen point removed'froi'n the aper: ture, and the latter suitably closed by a cork.

In Figs. 3 and 4, there is shown a modified form of the device in which 10 is the ink reservoir and the closure is made of peculiar form, the compressible bulb 11 being relatively smaller and insertion of the pen being formed in a flange which fits into the neck of the reservoir. The material surrounding the aperture is undercut at 17 to promote its elasticity. The bulb is closed at the top, and at the bottom is provided with a de endent tube 16 extending well within the iody of the reservoir. This modified form of the device is used just like the first form. The pen is inserted in the apertured mouth 14, point downward, over until the ink level is abovethe open end of the pen and the bulb is alternately compressed and allowed to expand until the pen is filled.

It will-,be seen that by the use of this de vice there isno need of the operator coining directly into contact with the ink and thus the likelihood of soiling the fingers is obviated.

What I claim as new is:-

1. A device for filling fountain pens, comprising an ink reservoir, a closure therefor aving an aperture adapted to be closed by the. insertion of the pen to be filled, and means whereby the pressure of the air within the reservoir may be varied.

.2. A device for filling fountain pens, comprising an ink reservoir, a closure therefor i aving a tapered. aperture adapted to be iaving an aperture adapted to be closed by the insertion of the pen to be tilled and means whereby the pressure of the air within the reservoir may be varied, consisting of a cornpressible bulb.
