Should the ink feed slowly or imperpered for the reception of a projecting cap, fectly at any time while the pen is in use, its (indicated in dotted lines,) and this end has flow may be compelled or hastened bya slight inward motion of the piston, although-ordinarily this is not necessary, as the ink will usually feed under the influence of gravity. The rearward motion of the piston is limited by the flange a, as above noted, which prevents its being withdrawn from the case in the event of its being moved rearwardly to too great an extent. Should it be desired to clean the device, both pen and feeder are grasped by the fingers and pulled away from the body of the case, thus also removing the cork plug and permitting free access to the interior of the case. It will be noted that the cleaning may 'be materially assisted by the use of the piston,

which can readily be manipulated, so as to thoroughly remove any solid particles which may have been deposited from the ink.

By providing the small tube-section d fit by use of this construction to employ a form of packing which could not otherwise be employed, unless the head (23 of the piston-rod were screwed onto said rod, which eonstruction would increase the cost of the device as well as weaken it.

I claim as my invention' 1. In a fountain-pen the combination of a casing open at its forward end and provided with a pen, a feeder for the pen and a piece closing said forward end of the casing, said feeder having means for positively engaging said piece, said means being capable of transmitting motion from the feeder to the piece, substantially as described.

2. The combination in a fountain-pen, of a casing having an opening in its forward end, a substantially cylindrical plug therein, a

feeder fixed to said plug, and a pen adjacent to said feeder, substantially as described.

3. The combination in a fountain-pen of a plug normally serving to partially close one end of same, a pen, a feeder adjacent thereto, said feeder having a projecting portion formed to positively engage the plug, substantially as described.

4. The combination in a fountain-pen of a casing having its forward end open, a substantially cylindrical plug fitted into said casing, afeeder adjacent to the plug and having its rear end formed so as to positively engage the rear face of said plug and capable of transmitting motion thereto, with a pen confined between said feeder and the case,substantially as described.

. 5. The combination in a fountain-pen of a casing having a substantially cylindrical bore, a pen having means provided to retain it in one end of the casing and a piston within said casing, said piston including a head portion and a rod fixed thereto, a tubular portion fitting over said rod and extending substantially the entire lengththereo'fiwith abody of material confined between the piston-head and said tubular portion, substantially as described.

6. The combination in a fountain-pen of a cylindrical casing having a pen in one end, a cap for the other end of the casing, an inwardly-projecting flangeat the cap end of the casing and a piston movable within the easing, said flange being placed to limit the rearward motion of said piston, substantially as described.

7. In a fountain-pen,. the combination of a casing having a substantially cylindrical bore, a cap for said casing, a pen and a piston, said piston including a rod having fixed to it a head, a tubular portion extending over the greater portion of said rod and having upon its rear end a head portion with a body of ma' terial in engagement with the interior walls of the casing and confined between the pistonhead and the forward end of said tubular portion, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALFRED B. DAVIS.
