Applicationfiled July 15, 1921; Seria1,No. 484,993.

To all whom it maywconcewt:

Be it known that I SAM EL "V. GCRONiA, a citizen of the Unitedstates, residing at Janesville, in the countywof'Rock and State of WVisconsin, have invented new-and useful Improvements ln-Fountaln. Pens, of

whichwthe following isa specificationu,

This invention relates to fountain .pens' and more particularlyuto fountain pens of the self-filling type. I

Anobject ofthe invention "ifs-to provide a self-filling fountain penwhich isfsim'ple in construction and does not embody any protruding structures necessaryin'the op-" eration of the filling mechanism as well as one in which the'operati'ng structure for the filling mechanism is conveniently located to be easily and" quickly operatedwithout requiring the removal of any caps," the movement of any levers oranalogous structures. f r

More specifically the invention comprehendsthe provisionof a self filling fountain pen wherein the fillingor emptying operation is performed by the rotation of a button or cap carried at one end of the barrel of the pen body, the saidbutton or.

cap serving to operate a pair of cams which in turn contract the 111k carrying bag for 30 creating a suction upon theexpansionof the bag for drawing ink 'thereinto. I Other objects of the invention will apk pear in the following detailed description and inthe accompanying drawing wherein: Fig. 1 is an elevation of the improved fountain pen without the closing cap.

Fig. 2 is a fragmentary longitudinal sec carrying bag 5. As is usual in self-filling fountain pen structures the ink carrying bag 5 is formed of soft rubber and after it has been collapsed the suction created by its expanding or reflexing action will draw the usual manner through the point 6. .111 the present invention the barrel 1 has ink .thereinto which ink is dispensed a. the

an inwardly extending flange??? at its end remote from the pen carrying end thereof. A ferrule 8: is inserted through the reduced opening in 1 the barrel 1 formed the flange-7 and it is provided withY-an routwardlyextending flange 9 which engages against; the innerend of the flange 7 as] clearly shown linFigure f the drawing.

The ferrule '8 extends" into the'sleeve 10) which is provided with. an annular inwardlyiextending flange l'l'forming a shoulder 12against which the annular flange 13 of r the V. ferrule 8 enga es for connecting the sleeve 10 to the'bo y 1 to-perniit rotation of the sleeve 10 relativetothe body. In as sembling the pen, the flange 13" is spun on the ferrule 8 after it is placed in position.

A cap 14 is threadably connectedto the 81681610 and it carries acam 15 The cam 15 is rigidly mounted in the-"cap l t'and has its inner end beveled .in both directi'ons-towards'its 1 center as clearly shown at 16' forming a wedge-shaped end' which. ex-

tends into a correspondingly recessed end 17 of the longitudinally movable cam 18. The cam 18 has. a radial lug 19 thereon which extends into; a recess 20 formed. in the sleevev 8 to prevent rotation of the cam 18 but permit it tomove longitudinally in tl1e'sleeve8, the sleeve being fixed against rotation. -The outer end" of the cam 18 is recessed and receives thereinthe end 21 of V the spring 22. The flat spring'22 extends longitudinally in the; barrel and, its end remotefrom the end 21 is engaged between the ink bag 5 and the barrel 1 adjacent the head 4 of the ink bag. A bag compressing strip 23 is carried by the spring. 22 being connected thereto by suitable rivets 24: in-

termediate the ends uf the spring and'strip. When the cap .14 is rotated the bevel end portlon 16 of the cam 15 riding over the bevel recessed ends of the cam 18 will move the cam 18 outwardly or towardsth-e ink bag 5, bowing the spring 22as shown in dotted'lines in Fig. 2 of the drawing,'and forcing the strip 23 towards the axis ofthe barrel 1 which'will compress the ink bag 5.

The foregoing operation willbe provided in the first half rotation of the cap '14: and the second half of the rotation of the cap will move thebeveled ends of the cams into. i

inventionnnay be constructed. in various re istration or en a ement ermittin the 23 b b O spring 22 to assume its normal position the use'of removable caps, projecting parts, or the like is eliminated except those actu-- ally used in the filling ofthe pen. It is, of course, to be understood that the other manners and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claiinis: M E

1. In a self fil ing fountain pen, a barrel,

a sleeve, a ferrule connecting said sleeve andbarrel to permit rotary movement of the sleeve, an lnk bag, means for coinpresslng said ink bag, a'longitudinally movable cam carried by said ferrule, ,a second cam rotatable with said sleeve and engaging said first named cam for operating said bag compressing means.

2. In a self filling fountain pen, a barrel, a closure for the butt. end of the barrel, a ferrule connecting said closure and barrel to permit rotary movement of the closure relative to the barrel, an ink bag, means for compressing said ink bag, a longitudinally movable cam carried by said ferrule,

and a second cam rotatable with said closure and engaging said first named cam for operating saidbag compressing means. 3. In a self filling fountain pen, a barrel, a closure for the butt end of said barrel, a ferrule connecting said closure and barrel to permitrotary movement of the closure relative tothe barrel, an ink bag, means for compressing said ink bag, a longitudinally movable .cam carried by the ferrule,

and means rotatable with said closure and engaging said cam for operating said bag compressing means.

4; In a selffilling fountain pen, a barrel, a'closure for the butt end of said barrel comprising a sleeve, a cap connected to said sleevefor rotary movement with the sleeve, a ferrule connecting said closure and said barrel to permit rotary movement of the closure relative to the barrel, a cam carried by said cap, an ink bag, means for comressin said inkba and means carried by said ferrule and engaging said cam for operating said bag compresslng means.

In testimony whereof I affiX my signature.
