in any suitable manner, herein. exemplified by the provision ofa leaf spring 18'wliich is u crowned lengthwise Aand dianietrically arplunger, a slight turning movement of the cover after said ends of the spring have penetrated said openings being sufiicient to lock ,the parts together in tensional engagement.

When applying the cap for the relling operation, the cover 14 is first removed from its normal position and placedon the opposite'endy of the cap, which is also erteriorlyV provided with a suitable thread 21 for the purpose. .k The plunger 17 is now released and freeftoV be moved to the opposite end of the cap which is done -by inserting the butt'end of the penholder, The plunger is provided at opposite points on the margin of its inner end with notches 22 which enable it to stradv dle the'springklSwhe'n advanced to the limit of. upward movement and to prevent turning of the plunger while connection between tlie penholderand Vplunger is being established.

This is done by eXtendingthe butt end of the .penholderincluding the caplO, into the interior of the plunger and then rotating the former whereby the thread 8 is induced toengage a corresponding thread 23 interiorly provided on the plunger as shown -iii Fig.

3. In performing this operation suitable,

. means are provided for simultaneously releasing the cap thereby opening the vents 12 and'13, said means being exemplified herein by the provision of longitudinal keys 24 arranged at opposite points `centrally u interiorly `of the plunger which are adapted to fitinto corresponding grooves 25 provided eXteriorly on the cap 10. Hence, astlie penholder isfrotated tofestablish connection with theplunger the latter is held. against rotavtion by engagement o'f'the'notches -22 with the spring18. while at the same time the cap 10 remains stationary by reason of the Vengagement of the, grooves 25 by the keys 24.

` As the threadsecuring the cap 10 is formed ina directionV opposite to that of the thread 23on the plunger the turning-ofthe penholder tothe right involves arelease of the butt end from the cap 10 which is moved` relativelyf thereto. in longitudinal direction. The cap' 10. is v'interiorlyx threaded throughout itslengtli which vis made sufficient vas shown inFiggi 3 to avoid completesep- Y `aration from'the penholder. atk all times during rotation of the latter within the plungent i V*To refill the barrel 1 the pen 2 is preferably 'wholly' immersed Ain the writing fluid at the source" of supply and while. thispositio-n the cap 5 carrying the plunger 17 isv retracted, care being taken bythe operator at the same u Y It will be understood time to place a linger over the vent inthe rivet 19 in the center of the cap 10, the upstroke of theplunger being adapted to evacuate air from the barrel through the vents at the top, thereby creating a vacuum which is filled by the fluid entering at the oppo-` site end through the duct 4. To avoid separation of the plunger from thecap 5 during retraction of the latter, a suitable stop may be provided, herein shownin the form of an expansible ring 26, seated in an annular recess of corresponding proportions provided in the outer wall ofthe plunger at awpoint preferably near the top, said ring being adapted to expand upon entering lan annular recess 27 of'graduated depth provided on the inner wall of the cap 5 at a point nearY its lowerextremity, whereby the cap at the bottom of said recess-presents ashoulder which is engaged bygthe ring.V Said ring is preferably slightly beveled on the lower margin .of its exposed surface as at 28 to prevent stripping of the threads 7 on theinnerwall of the cap.

It i'sdesirable, although'not essential, to construct the barrel 1 in whole or'in part of transparent ortraiislucentmaterial to aid the operator in ,detecting the levelof the vwriting fluidas it rises within the barrel plunger 17 and cap 5 from thepenholder being thereby simultaneously effected. Vhen this has been accomplished the vcover 14 of ythe'cap maybe restored toits normal position on the opposite end of the cap and the plunger` again secured thereto in the manner before described. p Y
