JULIUS n SCHNELL, or Ann Iiieuroit vi w 'JnRsnY FOUNTAIN =PEN Application filed .May: 2?,

This invention relatestofountain pens and primarily it is an improvement on the type ofpen embodied inmy already ssued Patent#l,1;4 4=,436 dated June 29, 1915.

: In this former typeof pen the slide or shifter, and more particularly the free end portion thereof, hasa tendencyto rise up beyond the circumference of thebarrel and which; action bends the frontendportion. of theshifter or slide upwardly. Furthermore, this action oftheslide or shifter in the former type of pen had a tendencyrto develop play at theback end portion of the slide orshifter anduwhich often results in pressure on the ink sacforcing out ink at the pen point, causing much trouble and great detriment to the pen. It is anobject of the present invention 7 to avoid these objectionable features.

Another object of the invention is to provide a fountain pen of thistype embodying a filling means including a slide or shifter and wherein the shifter is held in desired position in a manner to avoid protrusion of either end portion of the slide or shifter beyond the periphery of the barrel and wherein the shifter or. slide at all times moves evenly in a straight path of travel.

The invention consists in the details of construction and in the combination and arrangement of the several parts of' my improved fountain pen whereby certain important advantages are attained andthe device rendered simpler, less expensivevand otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. 7

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe thesame with reference tothe accompanying drawing,wherein Figure 1 is aview partly in section and partly in elevation illustrating a fountain pen constructed in v accordance with an embodiment of my invention;

The slots, 6 ofthe v ep l t :3 have ea l er I ee-Y rigid link vprovided at its opposite end with a fork 11 straddling and having direct contact with a curved lug 12. struck from the central part of an elongated presser bar 14.

This presser bar 14 is disposed within the barrel lengthwise thereof and its innermost portion is clinched or otherwise secured, as

I positionwith respect to the slide or shifter 3.

7 The spring arm 16 is provided therealong with a slot- 20 throughwl 1ich' the short link l0 worksf The outer portion of the slot-20, or that end portion ofthe slot 20: ad acent to'the applied pen section, is transversely enlarged, as atj2 0a,so that the forkIl w ll offer no hinder'ance or obstruction to the desired relative movements of the'several parts. The resiliency-of the arm 16 is such as to normally maintain the presser bar 14 in a position.

closely adjacent to'the wall' 'of the'barrel B and alsomaintaining the slide or shifter 3 in its normal position as'a result of the coaction between the fork 11 and the lug 12. At'this time it is to be statedthat the fork 11 coacts with'the inbow face of the lug 12.

I f With the parts just referred to in such normal positions when the pen section S is" applied'the tube or reservoir T, or inksac as it is also known, will readily enter the bar-- rel'B." By moving the shifter or slide 3 to.- fward the end of the barrel B with which the pen section is engaged, the presser bar 14 will operate to compress the sac so that upon release of the shifter or slide 3 the collapsible tube" willexpand drawing the desired quan- 'tity "of ink into the tube or reservoir, it being understood of course that the pen section has previously been dipped; into the desired source'of fluidf supply.

From the foregoing description it is thought to be obvious'thata fountain pen 'constructed'in accordance with my invention is particularly well adapted for use by reason of the convenienceand facility with i which it may be assembled and operated, and

it will also be obvious that my invention is susceptible of some change and modification without'departing from the principles and spirit thereof and for this-reason I, ido'not wishjto be understood as limiting myself to the precise arrangement and formation of the {several parts herein shown in carrying out v yinvention in; practice except as hereinafter claimed.
