This -invention relates to that class, or. fountain pens in which an expansible rubber 10 sack is provided within the barret and me . chanical means is provided m connection therewith for collapsing the same and, . more particularly, to that particular type of fountain pen in which a presser plate is 15 arranged to engage the sack throughout substantially its entire length, and a ever is pivotallv connected to the pen barrel m position to press the plate against the sack, to collapse the same, so that, when the sack 20 is permitted, to expand, it will be filled with the liquid in which the pen section has been ^dl Prior to my invention, various devices of the above-described character have been pro25 duced, but said devices have, so far as I am aware, been open to certain objections, some of the more important of which have been difficulty in operation, unreliability ot tne locking means for the operating lever, un30 sightly or inconvenient projections, and excessive cost of manufacture.

The objects of my invention are to provide a fountain pen, of the character above referred to, in which the. lever-operating 35 means is arranged to permit easy and convenient compression of the sack, and m which a convenient and effective means for locking said operating means is provided. Further, to provide a construction and ar40 r angement which will enable the production of a fountain pen which has a smooth, contmii ous surface throughout the length of the pen barrel, so that it will have substantially the same appearance as an ordinary fountain 45 pen, unprovided with mechanical means for collapsing the sack, and which is of simple and durable construction, so that it is unlikely to get out of order, and may be manufactured at a reasonable cost. JL acM complish these objects by the means shown hi the accompanying drawing, in which .

As shown in the drawing, the barrel a has the usual pen section &amp; mounted therein, and a. rubber sack c is provided, which is arranged in the barrel, and connected to a re- 7U duced portion on the inner end of the pen section. ___, . ,

A presser plate d is arranged to extend longitudinally of the rubber sack, throughout substantially the entire length thereof, 75 said presser plate being connected to a spring arm e, which is, m turn, connected to a metal split collar /, the latter being arranged to grasp a reduced portion b , ^onthe inner end of the pen section. The pen 80 barrel a is further provided with a straight, narrow slot a', which extends longitudinally thereof from a point adjacent the middle, to the end of the barrel, and partly across die end wall thereof, and an operating lever g 85 is mounted to swing in said slot a , about a pivot h, located in the barrel intermediate the lever, and in such a position that the exterior surface of the lever is flush with the _ surface of the pen barrel, when the lever, is 90 in its normal or inoperative position.

The operating lever is arranged to provide a presser plate engaging arm and an operating arm. The operating arm is provided with an inwardly-extending offset- 95 portion σ' and is thence extended beyond • the end of the barrel by a tip portion a preferably in central, almement with the • barrel when the lever is in its normal or inoperative position. For maintaining the 100 lever in its normal, inoperative or disengaging position with relation to. the presser bar and for otherwise assisting in the mam ual control of the fever, the barrel is pro- * vided with an end piece or cap i which is 108 retained to have a releasable engagement with the barrel. This end piece or cap is preferably made of hard rubber the same

14,397 as the barrel, and forms practically a continuation thereof or finished end to the barrel. The retention of the end piece or cap g to have engagement with the barrel for 5 maintaining the lever in its normal or disengaged position, is preferably obtained as shown, by externally threading the. extending tip portion g'² of the lever and internally threading the end piece or cap f, or It) rather a bushing y within the cap, to screw onto the end of the lever until it bears against the end wall of the barrel in the manner of a nut, and in which connection, _ tor this particular mode of retention, the .15 end piece or cap might be termed, a nut.

Γο prevent lateral displacement of the end piece when. in engagement with the end of the barrel, the end. of the barrel is snghtly cupped or recessed, and the ad20 jacent end of the end piece is correspondingly formed to enter the same, so that the end piece may be loosened or unscrewed to an appreciable extent before the lever can be drawn out· of its normal position.

To fill the pen, the nut i is unscrewed to the necessary extent, . and the lever g is swung outwardly, to cause its short arm to force m the presser plate, and collapse the sack, as shown in Fig. 3, so that, when the 30 lever is swung back to its normal position, tae expansive force of the sack will cause the ink to be drawn therein in the usual maimer. The nut i will then be screwed against the end of the barrel again, to lock the lever in its normal position. During the operation or the lever, the nut I provides a convenient handle, or means for graspinsr it with the fingers.

Figs. 7 and 8 show a slightly modified 40 iorm of my invention, in which, instead of arranging the pivot h' directly on.the hard rubber of the barrel, a metal band m is provided to receive the same, which is arranged about the pen barrel, flush with the surface 45 thereof, said band being also made to serve for ornamental purposes, if desired.
