To c/j wilma it may Concern Be lit kgnown that-I, EDWINy E. KRATZ, la` citizen 'ofthe :United States residingr at Kan,-A

Asas City, in thje, county of; aekson and State;

of Missouri, lhave invented certain new antlf usefullmprovements in Fountain Pens; and. Ifdo-declasekthe following to. be a full, clear, i and exact description ofthe invent-ion,suchV i aswfill enableiothers skilled in the art to which it appertains to malte'aind use the,

This, invention relates to self-fillingg-fo1intafapnslwdfthaprimry Object iS t0 pw videl an inexpensive, easilfy operated, fillertube-Voperatingl mechanism. The invention'iconsists in` certain novety parts andcombination of parts,` whichl will: be 'clearly referredto hereinafter, reference being had to the accompanying drawings, 1n. Which- Fig.: 1` is a vertical., longitudinal, sectional view through afountain penilcase sluowinfg, myx, invention partly .lin elevation and partly,Y in: section, the penreceiving` end of the case2 being, shown in,r elevation.

Referring now to the drawings by numerals of; referentie:

The outer case or shell 1 of the fountain pen which constitutes the penholder, may be of any appropriate construction, the speciiic details not beingr a part of m v present invention. The casing 1, however, is shown as provided with a longitudinal slot Q through which the manually controlled part of the actuator may project. The filler tube 3 maj,I be attached to the portion l of the pen holder in any Well known manner and it may lie Within the casing 1 in the usual Way. 1n order to cause a. collapse of the tube so that air will be expelled therefrom to permit ink to enter the tube in a manner to be well understood` I provide an actuat p t-hebar 5; The bar 5 has- 1922.

The free end of *theactuatinghar-` 5 `has an upturned lip 8, for thepurpomot preventing the end of the bar r5 from cuttingi.

The rlever or, actuator 17 is in the forxn ofjachanneh: des is and 190i which Stra-dais tfifup; standing projection 9V andare p igvotally se*- curecl thereto by a pivot orrivet-20.

When the parts-are norma-11j?, in posi as shown in Fig 1 thebar portion 7, of stripi will he fastened,` rigidly to the under normal conditiomy the latch Will'lie longitudinally of the case 1 so that the notch 16 will engage the lip 15; therefore, the lever 1T will be locked against movement. It will he noted that the length of the lever is Slightly less than the length of the slot 2 (see Fig. 1).

lhen it is desired to collapse the filler tube 3. the latch lever 17 must be disengaged from the lip 15. and the operator will slide the latch longitudinally toward the pen point` the springr connection G permitting a slight longitudinal movement of the bar 5 with respect to the bar 7 so that the disengagement of the notch 16 from the lip 15 can @103,12 the projection 9 extenclfssthrou y:

te i i in Fig. 1 `with the latch lever 17 in such position that the notch 16 will engage the lip 15 when the laLtch lever will be locked again.

`When the latch lever is thrown down into the position shown in Fig. 1, it will automatically move into engaging position with the lip because the tendency of the spring connection 6 will be to draw the bar 5 1ongitudinally far enough to cause the notched portion of the latch lever to move into eni" gagement with the lip 15. The end ofthe latch lever 21 is in the form of a lip which will overlap the lip 15 so that a smooth appearance will be presented to the observer.

It will be apparent that the device can be readily applied to the pen casing and that it will be effective in accomplishing the result desired.

What I claim and desire to secure by LettersPatent is:

1. A filler tube actuator for pens comprising astrip bent intermediate its ends to form two substantially parallel bars, the portion of the strip connecting the two bars having a spring tendency, an upstanding -`|projection on the lower bar extending through a longitudinal slot in the upper bar, the upper bar having means for attachment to a fountain pen shell, a pivoted latch bar on the upstanding projection extending -through the slot, and means on the pivoted latch bar for engagement with the means for securing the upper bar to the shell.

2. The combination with a fountain pen shell and a filler tube therein, of a bar norv"inally lying upon the filler tube, a substantially parallel bar spaced from the first named bar and having yielding connection therewith, the'seeond mentioned bar having a slot coinciding with the slot in the shell. an upstanding projection'on the first named bar projecting through the'slots in the second mentioned bar and in the shell, a pivoted latch lever connected to the upstanding projection, and means on the latch lever for removably fastening it to the edge of the slot in the shell.

3. A filler tube operating device for fountain pens comprising a pair of parallel bars, yieldingly connected together, one of the bars having a projection extending through a slot in the other bar, means on one of the bars for engaging the edge of a slot in the fountain pen shell, said means having a lip, and a latch lever connected to the lower bar and having a notch for engaging the means for connecting the upper bar to the shellof the fountain pen.

4'. A fountain pen filler tube actuator comprising two bars resiliently connected together, one of which is provided with a longitudinal slot and in spaced relation to the other har, an opstanding projection on the other har extending through the slot in the first named bar` means for connecting the first named har to the shell of a fountain' pen` and a pivoted lever connected to the projection adapted to swing into and out oi operative osition so that when in one posi tion it wil lie longitudinally of the shell and when in operative position it will lie transversely to the shell.

5. A fountain pen filler tube actuator comprising a bar bent over at one end and back upon itself to form a second bar having a spring connection between the two bars, the bars constituting an upper and EDWIN E. KRATZ.
