tending lengthwise of the pen barrel to-A gether with a barextending along the reservoir :tor the purpose ot collapsing the same in filling, and means Jfor returning the bar to its normal position after it has been relieved ot pressure. Such devices have, however,

been cumbersome or unsatisfactory for various reasons.

rllie object of my invention is to provide an improved and much simplified construction which is separate trom the rest ot the pen and readily removable and replaceable. To this end l make the presser bar and its support a distinct structure removable to gether, the support being retained frictionally and removably in position. rlhe simplest and best support for this purpose is a sheet metal collar which by its tendency to expand retains itself in place. -ll prefer to so construct this support that it will move `down as a Whole when pressure is applied to the presser bar and will assist the return ot the same by springing baclr into place when pressure is removed. l prefer to use a plurality ot collars having a common tongue.

Edy invention therefore consists in the subject matter describedin the specification and more particularly pointed vout in the appended claims.

Referring to the accompanying drawings: Figure l is a top plan view oit the pen showing parts of the outer casing in section, one part thereof being slipped to one side as is donewhen the pen isl to be iilled. Fig. 2 is aside elevation and section similar to Fig. l. Fig. 3 is a cross section on line 3--3, Fig. l. Fig.Y t inner tubular casing. Fig. 5 is an enlarged plan view of the yblank from which the presser bar su port is formed and of the presser bar. Fig. 6 is a perspective view of the presser bar and its support. Fig. 7 is a side elevation and section similar to Fig. 2 but showing the preferred-'form ot support the parts being in the position they assume in which it has been customp is a perspective view ot the when the ink reservoir is partially collapsed. Fig. 8 is an enlarged plan view of the blank from which the referred form of support is made. Fig. 9 is a perspective view of the presser bar together with the preferred form of support.

ln the pen, as thusv illustrated, 1 is the usual nozzle; 2 is a part of the outer tubular casino1 or barrel; and 3 another part which may be moved into or out of contact therewith. 1vlithin this outer casing, l have shown a tubular inner casing 4 providedA with a cut out oi slot 5 and inclosing the flexible ink reservoir 6 which runs lengthwise of the pen.

7 is the usual presser bar accessible through the slot 5 when the parts of the outer casing are separated so that the pen may be filled. In accordance with my inlvention'the bar is part of a distinct structure which is removable as a whole from the rest of the pen. The part of this structure constituting the support for the bar have illustrated as a spring collar 8 formed trom a sheet metal blank 9 (see Fig. 5) having a tongue 10 extending lengthwise of the pen and to which the -presser bar is secured. The material for this collar is preferably sheet steel to give it the' requisite strength and elasticity. lThe part of the blank designed to torni the collar is bent into tubular form to lit the bore ot the casing within which it is to be placed, the collar by 'virtue ot' its tendency to expand retaining itselt and the presser bar in position trictionally and removably in the casing. l prefer to employ an inner casing and' to locate the spring collar in the open end thereof.

.l rind it advantageous to make the sup- .port tor the presser bar in suolil `a manner that the entire support as well as the longitudinal tongue will yield when pressure is applied to depress the presser bar and will, by its spring action, assist in returning the bar to its lnormal position. rThis l iind is` accomplished by separating the ends ot the collar so that the entire collarl may move downward and spring back again when pressure is removed.

The above description hasdealt more particularly with the construction illustrated in Figs. 143. It remains to describe the pre- 'l'erred form of support tor the presser bar as illustrated in the remaining figures.

Ihave round that by providing a plurality of spring supports with a common tongue, to which the presser bar is secured, the motion sure is removed.

'v :'.Referringto Figs. 7lthe noz'zle 1, outer" casing parts 2 and 3, inner'y casing 4, slot 5,

, collapsible ink reservoir 6 and presser bar 7 are the same as the corresponding arts in the other ures'.- The support gor the presser bar however, is formed from -a double blank T9 of sheet metal (see Fig. 8)A whose vends are connectedby the common tongue '10fthe said ends being bent to form spring collars 8', 8. l I prefer to secure the presser bar 7 to the tongue 10 `midway between the collars'8, S', and to locate the point of connection dat the middle of the presser bar 7. The action is more even and accurate when this 1s done.

It will be evident that my inventionv has jv thev meritsof extreme simplicity, economy What I claim as my casing, a' flexible ink reservoirlextending lengthwise of. the pen in saidi casing, a presserbar extending along saidreservoir,
