To all whom it may concern.'

` Bc it known that I, WAI/ren A. SuEAFEEn, a citizen of the United States, residing at F0rt Madison, in the county of Lec and State of Iowa, have invented certain new and useful Improvements in Fountain-Pens and I do declare the following to he a'l'ull, clear, and exact description ol the invention, such as will enable others skilled in the art to.

which it appcrtains to make and use the saine. v

'.lhis invention relates to new and useful improvements in fountain pens lemploying an elastic ink tube or reservoir and conipressing means for compressing the tube or reservoir to create a vacuum therein, a suction being cstal'ilished through the pen holder section during the expansion of the elastic tube or reservoir whereby the saine will be refilled with ink during the expansion of said tube into its normal position:

With this and other' objects in vie-W," the invention consists'of certain novel features of' construction, combination and arrangement of parts, as will be more fully described and particularly pointed out the appended.

claims.

' In the accompanying drawings Figure 1 is a central longitudinal section illustrating the preferred embodiment of the invention; Fig.x2 is a, similar view with the ink reservoir or tube compressed by the com ressing means; Fig. 3 is a cross section ol Fig. 2 taken immediately in front of the o erating lever'and looking toward the same; ig. 4 is a detailed perspective view on an enlarged scale of the operating lever, and, Fig. 5 is' a similar view of the locking band or ring eni- Eloyed in connection with the invention'.

ig. 6 is a detail ers'pective view of one end of the operating ever on enlarged scale.

Referring more particularly to the drawing the numerals 1, 2 and 3 indicate respectively the outer casing, inelastic ink reservoir, or

' jacent to the inner end o an operating lever 5, said lever when in its4 tube, and the en holder section of the'founare of any ordinary or approved construction and 'therefore need no parliciilar'description..

In carrying out the invention the outer casing. is formed near its outer end with a lon itudinally extending. slot 4 between the wa s of which and at a point preferably adthe same is pivoted normal position extending the full length of the slot. i

An annular groove 6 is formed in the outer casing at a point adjacent to the free or handle end of' the operating lever whicli'projects into the groove of' thecasing and is re,

duced as at 9 nand one end of such reduced portion bent sliglitly outward as at 10,

ocl-:ing band or ring is'f'ornied at its inner edge with a suitable of the end walls as 12 of the recessedportion being vbeveled inwardly to engage under the reduced end portion of the operating lever when the'locking band or ring is turned in a left handed direction irl-which case the handle end of said lever may be readily grasped by the operator. p

By turning the-lockingband or ring in a right-handed direction sufficiently to bring the recessed portion thereof op osite the reduced handle end portion of t the outer casing in which position 1t ma be securely looked or held by turning the loclliing band or rin'g sulliciently.

A compressing member 13, preferahl` in the forni of a flat rectangular metallic ply te, is arranged between the ink reservoir or tube and the outer casing, the outer end of the plate being formed witlA two longitudinally spaced apertures 16 designed to receive corresponding transversely eiitending. ruide pins 17 arran ed at the outer end of saicil` ing. This' p ate extends nearly the full length of the the walls of the same may be compressed to create a vacuum7 and upon moving the-operating lever into its normal osition, the eX- pansive force of the materia composing t ink reservoir will cause its A, their normal position and in doingr so the ink will be drawn through the pen holder section into the tube.

When thc parts are in their normal osi-I tions, the longer ai'in or handle ofthe ever fits or lies in the slot of the outer casing and extends a proximately the full length of the t l e operatinglever, said end is permitted to again resume, g its normal position in the slotted reservoir or tube' in order that` The peripheral recess 11, oiie l ortion of .y

saine, ani 1s held securely in position bythe locking band or ring 8. f

While I have shown and described the preferred embodiment of the invention, it is s of con# be understood that various changes in the-- form, proportion and minor deta struction may be resorted to Without departing l'from the principle or sacrificing any of gitiidinally extending slotJ longitudinally. Vspaced guide pins arranged at the outer end of the casing, an elastic ink reservoir arranged within the casin a compressing plate arranged between t ie reservoir and casing one end of said plate being formed with longitudin ally spaced apertures to receive said guide pins, an operating lever ivotally mounted 1n the slotted portion of t e casing,- the free end of the former being designed to engage and move the com ressing Plate into coinpressing position lwien the ree end of the ever is swung outwardly and locking means for normally retaining the free end of said lever in inoperative position;

2. Adevice of the character specified enibracin an outer casing formed with a longitudina ly extending slot and with an annular or peri heral groove adjacent to one end of its s otted portion, an elastic ink reservoir arranged within the casing, a compressing plate arranged between the reservoir and casing, an operating lever pivotally mounted in the slotted portion of the casing, the pivot d end of said lever being designed to engage the compressing plate to move the latter 1n one direction and the opposite or free end of l maar extending slot, a reservoir arranged witliin the casing, a compressing plate arranged between the tube an (leasing, an operating lever for moving the compressing plate into compressing position, pivotally mounted in the' slotted portion of the casing, the -free end of the lever terminating, in an outwardl bent portion, and a locking ring formed wit a eircuinferential recess' in one edge mounted uponthe easin f adjacent to the free end of the lever, lone o the end wallsof the recessed portion of said ring being beveled inwardly to engage under the outwardly bent portion of the lever.

In testimony whereof I have hereunto setv my hand in presence of two subscribing witnesses.
