The cap Gis of a size sof that it is` adapted to fit either end ot the barrel, its inside diameter' 41being of` substantially the same size the outside 17 of barrel A. i `Its position onfthe butt end is regulated by pin 16 y its'imcl` 44 engaging the stop 14 on'barrel A.

On opposite sides are the holes 42, 42, through which pass the release buttons 49, 49 adapted to allow the push button H tomove a greater distance than ordinarily This push `buttonH ispreferably hollow and'` has closed ende() which projects out `trom the .end 40 of cap Gr.

and 5 `while the thumb l`presses on button-IH moving it in the distance between 56 and 12 thus compressing the bulb C slightly and forcing` out a drop of ink When however itis desired to till the penj it can be held with the fingers 3, 41and' 5 and the thumb l, the thumband finger 3 pressing in on release buttons 49, 49 so that the finger 2 can press the push button H in and as the transmitting means or legs 52, 52 are moved inside stop 12 as shown by the dotted lines in Fig. 10, they7 together with plunger F Withits stem 31 can move a greater distance thus compressing bulb C a larger amount when it is desired to till the pen.

As shown in Fig. 12 the cap Gr can be put on the opposite end of the pen and its construction is such that it will` not interfere with the point B. Y i

`11, 12,1) is the compressor, `F and its accessories is the operatingmember, 11 isthe opening therefor, Gr thecap, H the pressure `control member `while 521, 52, 49, 49 comprise the transmitting means;

` lin Figs. 6A, 6B and 6C`I show7 a very much simplified device whichcan be usedif desi-red; ,i i

The bulb C is of the same type `as shownin Figs. 2, 3 and 5 and the barrel Lis of `the 75 `usual type with a compressor openingy`330 similar to 130 and performing the samefunction as 11 the compressor `33l`being positioned in line with hole 330 and is shown coming close to its inside'.` When cap M is on the endof the barrel which isoppositethe pen point the guide opening 340 `for the transmitting member 341 registers with"compressorj opening 330. y

This transmittingmember `isshown as a shank 341 slidablein guideopening 342 forming an outlet for 340 .and member 341 terminates inthe conical head" 343 the parts being of such size and position that the whole of 343 can be housed in guide opbning 340 as shown by the dotted lines when the pressure controlmember 344 `shown as a pushl button head is moved out to the dotted line position. With this constructionit is not necessary to have anyreturningf spring as the member 344 can move in and out looselywhen the cap M is on the pen end and when it is positioned on the other end of the barrel, the conical surface of the part 343` causes thepart to move out so thatcap M can be slipped on without difficulty. When the openings 340 and 330 register however, the pressure'icontrol member 344 can bepres'sed in more orlfess transmitting the pressurethrough members 341 and 343 to the compressor 331, which has no head,`and thence to bulbC. The natural elasticity of bulb @or the* springot compressor 331 will bring thcparts back in place when released. he device shown inAF ig. 6A reduces the number of opera-ting parts totheminimum. Member 344 can be positioned near the disc shaped end 346`com1non`onsuchcaps asM or it can `be positioned in `an extension thereof 345as shown inFigsB `and 6C.

`As shown in Fig. GC" this construction has the advantage that theV part 343 is exposed and that `cap M can be put on barrel L by starting it atan angle" and then straighten` ing it out as shown by the dotted lines.
