Patented Oct. 14, 1930 GEORGE Mosrlsor Fiennes ISLAND, NEW YORK FOUNTAIN PEN Application fued June 11,

a This invention appertains to fountain pens a* ofthe self-filling type and has for one of its primary objects the provision of a novel and simple means for insuring the filling of the y.barrel of the pen, 'the device being so constructed as to Vpermit a maximum amount of ink to be contained in the barrel.

" 'Another important object ofy my inventiony is the provision of positive means for drawing the ink in the barrel,'sa`1d means embody- *Y ing apiston sleeve slidably mounted within `the barrel and operable upon outward slide` y'the ink into the barrel..

ing movement thereof'in the barrel to draw "A further salient object of my invention is the provision Of'positively lockiligthe slid-v f ino` iston sleeve in the barrel in its ino aer- 'attive position againstaccidentaly movement Y while'the penis in use and means for limiting .the outward sliding movement of the pist-On' sleeve when ythe saine isbeing Operated toy draw the ink into the barrel.

VA still further object of my invention isr to provide novel means for arranging the barrel and the piston sleeve relative to one another so that the leakage of ink between the barrel and sleeve will be precluded and so that acompact structure will be had.V

A still further Object of my invention is to provide a self-filling pen of the above. char- 'acterj which will be durable and efficient in use, onelthat will be simple-and easy' to manufacture, andy one which can be placed upongthe market at a reasonable cost. s

ZWith these and other objects in view, the

linvention `consists. in the novel construction,

i arrangement and formationof parts, as will be hereinafter more specifically described,

claimed, and illustrated in the accon'lpanying drawing, in which drawing:

trating the novel locking means and guide for the piston sleeve;

Figure 4 is an enlarged fragmentary longitudinal sectional view through the improved pen illustrating the novel locking means be. tween the barrel and piston sleeve, the piston sleeve being in its locked position Figure 5 is a detail transverse section through the barrel and sleeve taken on the line 5- 5 of Figure Ll looking in the direction of the arrows;

l.Figure 6 is a detail transverse section taken Yon the line 6 6 of Figure l looking in the direction of the arrows;

1' Figure 7 is an enlarged fragmentary longitudinal section taken'at right angles to Figure l illustrating the novel locking means employed and showing the 'piston sleeve in its unlocked position and being withdrawn from the barrel; y

Figure 8 is a transverse section taken on the line 8 8 of'Figure 7 looking in the direction of the arrows, and s Figure 9 is an enlarged transverse section taken on the line QMS) of igure l looking in the ldirection of the arrows. i

Referring to the drawings in detail, where! in similar reference characters designate Oorresponding parte throughout the several views, the letter A generally indicates my improved fountain pen which comprises a barrel l0 open at its rear end and having its forward end contracted for receiving the sleeve plug l1 for the reception of the feeder bar l2 and pen point or nib 13. y

Slidably mounted within the barrel l0 is a piston sleeve l5 whici is closed atits outer cndby a suital'e head 16 which forms in con junction with the'sleeve a stop shoulder 17 for engaging the eurer end of the barrel when the sleeve inV innermost position, the outer surface of the head being of the same diameter as'the outer Vdiameter of the barrel surface of the barrel.

From the description so far, it is obvious 'grasped and the piston sleeve pulled outward from the barrel, a 'suction will be caused in the barrel thereby permitting the drawing of ink into the barrel i cross slot opening out through the opposite faces of the cross bar, the locking lugs being adapted to be received in the' cross slot upon the registration of the first slot With said lugs, the barrel being adapted to be turned to an arc of 180o to dispose the lugs in the cross slot at right angles Vto the first slot, whereby j to bring about locking of the sleeve Within the barrel.

groove.

' ried by the inner end of said rod and including a plurality ofrresilient arms, and radially lextending lugs on the terminals of said arms, the lugs being adapted to be sprung into said 5. A fountain pen vof the self-viilling type,

, barrel having its rear end open and provided Witha lock groove on its inner surface adjacent to the innerk end thereof, a piston sleeve slidably mounted in the said barrel and having a closing head on its outer end, a guide rod for said sleeve, a cross bar carried by the Y sleeve adjacent to the inner end thereof slid- `ably mounted on said rod, a foot carried by Y the inner end of said rod and including a plurality-of resilient arms, radially extending lugs. on the terminals lof said arms, the lugs being adapted toV be sprung into said groove, and means for detachably locking the rcross bar to the rod when the piston sleeve is in its innermost position. f

6. A fountain pen of the self.-lilling type comprising abarrel, an ink feeding and Writing mechanism at the forward end ofthe barrel, the barrel having its rear end open,

.piston sleeve slidable within the barrel, and

interlocking members carried respectively by the interior ofthe piston sleeve and the for- Ward end of the barrel engageable when the pistonsleeve is in its extreme forward positionin said barrel. f

V7. A fountain pen of the self-filling type 1 comprising a barrel having an ink feeding and Writing mechanism at the'forward end thereof and having its rear endopen, a piston e sleeve slidably mounted Within said barrel, an

axially disposed.guidel rod in said barrel, a locliiigdevice carried by the interior of the piston sleeve for locking engagement with thev rod When thepiston sleeve is in its' eXtreme forward position, and means on said rod at the rear end thereof for llimiting the outward motion of said piston sleeve.
