l To fzZZ whom e' may concern.

Be it known that I, JAMES Lsnemim, a resident of Detroit, in the countyc- Wayne and State of Michigan, have 'invented oertain new and useful Improvements in Fountain-Pens; and l do hereby deolarethe ol-Y lowing to be a full, clear, and exact description or" the invention, such aswill enable others skilled inthe art to which it appertains to make and use the same. n

This invention relates to improvements in fountain pens and particularlyfto that type in which compressible rervoirs are employed to facilitate the filling' ot 'the pen, the object of the invention beingrto provide simple and efcient means for lcompressing the reservoir in a manner toreduce to a minimum, wear on the flexible material of the reservoir and prevent possibility oi its becoming detached from the nipple'on the nib-carrying member of the device.

A further object is to so construct compressing means for the exible tube or reservoir, that the use of returning springs shall be obviated and sotiat'the deflection or the reservoirsliall be accomplished grad ually from the upper toward the lower or forward end thereof, and the inflation in the reverse direction, whereby the gradual and complete dll/ing of the reservoir shall .be accomplished/'with a minimum amount of strain on the parts manipulated.

With these and other objects in view', the invent-ion consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

ln the accompanying drawings, Figure l is' a planl View partly in section and partly broken away, illustrating my improvements. Fig. 2 is a 'view in section at right angles to Fig. l showing the parts in normal position with the flexible reservoir inflated, and Fig. 3 is a View similar to Fig. 2 showing the reservoir deflated.

1 represents a metal tube, the Jforward part of which is secured within a hard rubber barrel-portion 2 and the rear or upper part of said metal tube is vnormally covered by a removable hardlrubber barrel sect-ion 3. A nozzle-section 4 is secured within the lower or forward end of the tube l, :for the accommodation of a pen nib 5 and a euitable for attachment ot the-lower or forward end of a lexible tube or reservoir?, preferably constructed of soft rubber.

A presser bar 8 is located within the tube l' and projeci's through and is guided in a slot 9 in the rear or upper end of said'tube,

and access to said presser bar bythe linger of thelnser, will be had through an opening 1G located inthe wall of the tube preferably between its center and rear or upper end. rlhe. presser bar is of suihcient length to lengage the lie'xible tube or reservoir pnactically throughout its entire length vand the lower or forward end. of .said-bar is upturn'ed slightly, as atil tol avoid injury to the rubber of the flexible tube or reservoir.

A link 12J is pivotally 'attached at its forward end to the tube l as at i8, 1orwardly of the opening l0 in the tube l fand at its rearornpper end, said linl is pivotally attached as at 14 to the presser bar 8 near the forward end of the opening 10.

With the construction and arrangement of parts above described, it will be apparent, that when the operator presses at l() against the bar 8, said bar will be caused to move downwardly to collapse the rubber tube or reservoir Zr-the forward end ll. of

said bar bearing againstthe inner wall of' the tube l until the upper end of said bar shall have been fully depressed, after which, continued pressure against the bar 8 will cause it to descend and finally assume the position shown in Fig. When the presser bar 8 is thus operated, the tube '7 will be collapsed from its rear end forwardly, and when pressure is removed from said bar 8, the latter will vbe caused to move to its original position (as seen in Fig. 2) bythe resiliency of the rubber tube, the inflat-ion of said tube being progressive from its "fore ward toward its rear end and caused to become completely tilled with ink if the nib 5 be immersed in ink during' such inllation ot" the rubber tube or reseiwoira During the movement of the presser bar, it will be guided and prevented from lateral displacetl, and when the presser bar is being depiies'sed, said linl will also cause the presser bar to Inovefor# wardly, somewhat, crowding the .rubber cik the tube'l forwardly and thus avoiding in jury to the rubber tube or displacement of s ment by the link l2 and the slot the from the nipnle d loog fies 4 presser bar at what claim as new and desire Ato' LettersPatent? is:
