FOUNTAIN-PEN.

Specification of Letters Patent.

Application led January 19, 1911.

Patented May 9, 1911.

Serial No. 603,432.

To all whom it may. concern:

Be it known that I, HENRY B. LEVY, a citizen of the United States of America, residing in Manhattan borough, city, county, and State of New York, have invented cer- 4tain new and useful Improvements in Fountain-Pens, of which the following is a full, clear, and exact description.

This invention relates to an improvement in the so-called self filling fountain pens, the object being to provide a fountain pen of this character that may be converted into the ordinary fountain pen, that is to say, into'that form of fountain pen, the barrel of which is filled by means of a dropper. To provide a fountain pen of the self filling variety adaptable for conversion into the ordinary fountain pen is of great advantage for the reason that should the bag, employed for self filling purposes, become ruptured by corrosion or misuse, the said bag, and means for compressing same, may be removed and the barrel of the pen utilized ast-he reservoir `for the ink.

To carry out the object of my invention, I preferably construct the self lling devices of my improved pen in such manner as to adapt them for attachment to the pencarrying-section of the pen, and also to mount them in such manner as to adapt them for ready removal should the bag or compressing device therefor, becomeunfit for use.

My improved device for self filling founf vention in detail, the novel features of which I will finally claim, reference being had to` the accompanying drawing forming part hereof, wherein:

Figure 1 illustrates a side elevation of the greater part of a fountain pen constructed in accordance with my improvement, the barrel thereofbeing shown in section; Fig'. 2 is a similar view, on a larger scale, looking from the opposite side of the pen, the barrel being removed; Fig. 3 is an enlarged cross-sectional view taken on a line -a in Fig. 2; Fig. 4 is a similar view, taken on a linol -5 in Fig. 2; and Fig. 5 is a longitudinal central sectional View of the ink bag and compressing device therefor, a portion only of the pen section being shown.

Referring to the drawing the pen section of my improved fountain pen is indicated by 1, while 2 indicates the barrel portion ther-cof, the barrel portion being screwed on to the threaded lug 3 of the pen-section as is usual in fountain pen construction.

By referring to Fig. 5 it will be seen that the pen section l is alsoV provided with a reduced projection or lug 4v which projects from the threaded lug 3, the surface of the lug 4 being smooth. The function of the lug`4 is to support a compressible ink reservoir or bag 5, made preferably out of rubber.

One of the principal features of my invention is the cradle or conveXed semi-cylindrical support 6, which supports the ink bag 5 throughout substantially its entire length. The cradle 6 not only supports the ink bag but also acts to secure or hold the open end 8 of the bag in place upon the lug, or projection 4. To hold the saidend of the bag upon the lug 4 I provide the adjacent end of the cradle 6 with a ring 7 which is of a size sufficient to slide over the end 8 of the bag 6 and squeeze it against the projection 4. In other words, the internal diameter of the ring 7 is slightly less than the diameter of the projection 4, plus the thickness of the wall of the end 8 of the bag, whereby the end 8 of the bag is held in place upon the projection 4 by pressure. rIihe bag 5 can be removed from the projection 4 when the cradle has been pulled 0E. The ring 7 is preferably made integral with the cradle 6.

To compress the bag 5 in order to fill it with ink, I provide a conveXed presser-plate 9 which is hinged to the cradle 6 as at 10. I preferably make the late 9 longvenough to compress the bag su out its length.

As can be seen in Figs. 3 and 5, the cradle 6 receives or supports about one-half of the entire bag 5 circumferentially and longitudinally thereof, and is thereby rendered fit to support and protect the said bag when the pen section 1 is removed from the barstantially throughrel 2, in order that the said bag can be handled as a comparatively rigid structure and easily filled. As can be also seen in Fig. 3, the plate or compressing device 9 covers 'Will react and 'lill with ink.

it the bag 5, compressing device 9 and cradle.

6. The pen 11 and feeder-bar 12, a portion only of each being shown, are then inserted into an ink supply, and the compressing device 9 forced toward the cradle 6, a recess 13 in the cradle G permitting the finger of the user to more thoroughly depress the plate 9.

This action compresses `the bag or sack,

thereby excluding the air therein. When the compressing device is released the bag 5 The pen section 1 with connected cradle and sack can then be screwed into the barrel 2, at which time the pen is ready for use. y

Should the sack 5 become punctured or otherwise rendered unit for use, it can be readily removed from the pen section 1 by removing the cradle 6. After the bag and cradle have been removed from the pen section, the pen may still be used by filling the barrel 2 by means of a dropper, as is usual. The failure of the bagto perform its function as a reservoir does not destroy the pen for further use.

Having nonT described my invention, What I claim and desire to securefby Letters Patent is:

1. In combination with the pen section of a fountain pen, a semi-cylindrical support carried thereby, -a compressible ink reservoir supported by said semi-cylindrical sup- 'a fountain pen, a eompressible ink reservoir carried thereby, a semi-cylindrical support for sald reservon', a ring carrled by sald support adapted to hold said reservoir in position upon said pen section, and a convexed compressing device for said reservoir pivotally mounted on said semi-cylindrical support.

3. A self filling device for fountain pens, comprising a compressible ink reservoir, a semifeylindrical cradle adapted to su )port said reservoir throughoi'it the length t 1ereof, and a convened compressing device pivotally secured to'said cradle and adapted to compress said reservoir throughout substantially the length thereof.

4. A self filling device for fountain pens, comprising a compressiblel ink reservoir, a semi-cylindrical cradle adapted to support said reservoir throughout the length thereof, a convexed compressing device, pivotally secured to said cradle, and adapted to coinpress said reservoir throughout substantially the length thereof, and means carried by said cradle adapted to secure the open end of said reservoir to an element of a fountain pen.
