PAUL, MINNESOTA, A CORPORATION OF MINNESOTA FOUNTAIN PEN Application filed February Our invention relates to fountain pens wherein it is desired to provide means for operating the ink sack to collapse the same when it is desired to expel the air or the ink in the sack. V

A feature of the invent-ion is an extremely simple, inexpensive construction with only two operating parts, namely the lever and the ink engaging or compressing bar.- These two parts operate in a mannerso as to force the ink sack into a collapsed state when the lever is raised, and to permit the sack to expand when the bar is elevated by lowering the lever.

It is also a feature of the invention to provide means forsupporting the lever directly by the casing of the fountain pen which may be made of metal or any other suitable material. By a particular construction, yet

simple, we look the lever against disengagement from the casing or barrel of the fountain pen when it is in operating position. It is only possible to remove the lever when the same is rotated into an inoperative position insofar as the bar is concerned and over far enough so as to release it from the casing.

This can only be accomplished when the ink sack presser bar is removed or disengaged from the operating lever.

Our invention also includes a lever adapted to carry and lift the ink presser bar, including means 'engageable over the operating end of the lever to lock the lever and bar together againstfree disengagement, but permitting the same to be-separated, if it is desired, thus forming a catch with the inner operating end of the lever and. the sack presser bar. This construction provides means for preventing the presser bar from slipping out of the barrel when the'ink sack and pen point are removed' Yet the presser bar can be released from the leverby engaging the same and pulling it sufliciently to release the catch.

These features, together with other objects and particular form of construction of our fountain pen will be more fully and clearly set forth in the specification and claims.

Figure 7 is a section on Figure 6. r

In the drawing our fountain pen A is adaptthe line 77 of ed to be provided with a writing nib 10, held in the ordinary manner in the section 11, which is provided with the shank 12 and to which is secured the ink sack 13.

The fountain pen A is designed to receive a largeink sack 13 and is constructed with a metallic shell or barrel 14, which is attached to the shank 12 in a manner to hold the barrel 14 rigidly secured to the section 11. The barrel 14 forms a cover for the ink sack 13 and for the lever operating mechanism B, which is adapted to press the sack so that it can be filled with ink.

The lever operating mechanism B includes the finger lever 15 which is formed with an operating end 16, locking fingers 17 which are adapted to engage the barrel 14: to hold the lever in inoperative position or-closed against the barrel.

The operating end 18 ofthe lever 15 is formed with outwardlyprojecting lugs 19 which are adapted to engagein the channels 20 formed in the ink presser bar 21. The engagement of the lugs 19 inthe channel20 causes the presser bar 21 to be lift-ed'orlowered as the lever 15v is operated, as illustrated in Figure 2. Depressions 22 are formed in the flanges which form-the channels 20 of the presser bar 21 which formstops so as to limit the movement of the presser bar 20 on the lugs 19. The lugs 19 are'adapted to engage in the channels 20 freely so that the presser bar 21 can be slid onto the lugs 19 when the lever 15 is pivotally attached to the barrel 14. The construction of the presser bar 21 is i such that the spring of the material will permit the lugs 19 to be snapped beneath the depressions 22 at one end so that the presser bar 21 is locked against freely sliding back and forth on the lugs 19, when it is in operation, between the limits of the stops or depressions 22. An opening 23 permits the presser bar 21 to be engaged by a Wire or other suitable means so that it can be pulled sufficiently to release it from the lugs 19, permitting the lugs to pass beneath the depressions 22.

The lever 15 is formed with a pivot opening 24 which is adapted to engage the bar 25 formed integral with the barrel 14- and extending across the lever slot 26. The lever 15 is adapted to be locked to the pivot bar 25 so that it will not become disengaged there from in operation. To release the lever 15 from the pivot 25 it is necessary to rotate it into the position illustrated in Figure 4, after the presser bar 21 has been disengaged from the lugs 19. The lever 15 cannot be removed from the presser bar until the same is disengaged from the lugs 19. When the lever 15 is rotated into the position illustrated in Figure 4 the slots 28, which extend from the edge of the lever to the pivot opening 24 and which are of approximately the width of the pivot bar 25, permit the lever 15to he slid over the bar 25 or disengaged therefrom. In attaching the lever 15 it is slid onto the bar 25 through the slots 28 to position the lever as illustrated in Figure 4 and then the lever is rotated so that the operating end 16 will lie with the spring fingers 17 engaging the sides of the slot 26 adjacent the recess 29 which is adapted to receive the fiat end 30 of the lever 15.

A feature of primary importance in our invention resides in the simplicity of construction, the small number of parts and the effective operation of the lever and ink sack compressing means. In our fountain pen it is desirable to employ an ink sack with sufficient firmness and of a suitable thickness to the Wall of the sack so that a good substantial ink sack is provided having long wearing qualities and being adapted to readily expand in position to draw a large quantity of ink into the same. No spring means is employed for lifting the presser bar 21 from the sack but the particular construction is so designed and arranged as to cause the bar to be lifted away from the ink sack and held up against the inner surface of the barrel H when the lever 15 is operated to elevate the bar 21, thereby permitting the ink sack to fully expand and receive a substantial quantity of ink. The spring fingers 17 engage the sides of the slots 26 in the barrel so as to hold the same locked out of operating position. In this position the lever holds the presser bar 21 locked in elevated position away from the ink sack 13. The presser bar may be made with or Without the indentations 22 and when the bar is held locked up against the inner surface of the barrel by the lever 15 it is held against sliding within the fountain pen. Then the lever is released and moved into operating position then the bar 21 may be freely disengaged from the lugs 19. lVith the metallic barrel of our fountain pen only two operating parts, outside of the barrel, are employed, thereby providing a 10st simple, yet very effective fountain pen construction.

lVhile we have illustrated a particular form and construction of our fountain pen in the drawing wedesire to have it understood that the same is only suggestive of a means of carrying out our invention and that the particular construction may be varied and applied to uses other than those above set forth, within the scope of the following claims.
