N. KoPLow FOUNTAIN PEN CAP LOCK I 'Filed Jui 10. 1925 Patented May 25, 1926.

UNITED STATES NATHAN KOPLOW, OF SIOUX FALLS, SOUTH DAKOTA.

FOUNTAIN-PEN-QAP LOCK.

Application filed July 10, 1925. Serial No. 42,658.

This invention relates to certain new anduseful improvements in fountain pen cap locks, and the primary object thereof is to provide means for holding the cap agalnst unscrewing, thereby to prevent accldental disengagement of the cap with consequent damage resultant from the ink.

The invention further aims to provide means'of the type described which does not detract from the usual appearance of the pen and which is inconspicuous.

In the drawings Fig. 1 is a side elevation; Fig. 2 is a section on line 2-2 of F g. 1; Fig. 3 is a section on line 3-3 of F g. 1; Fig. 4 is a section on line 44 of Fig i; Fig. 5 is a section on line 5-5 of Fig. 1. In proceeding in accordance with the present invention, 1 designates a fountain pen of any type having the usual cap 2 threaded thereon. A lever 3 is formed with openings 4 on its opposite sides, and is received between the sides 5 of the base 6 to which latter the lever is pivoted at 7. The base 6 is embedded in the pen body and the sides 5 thereof are formed with projections 8 adapted to snap into the openings 4. In this manner, the lever is held latched in normal or inoperative position. The cap 2 is provided with a keeper 1n the form of an opening 9 which latter is disposed adjacent to the free end edge of the cap and conformably receives therein a pin 10 on the free end of the lever 3. It will thus be seen that the pin 10 of the lever 3 engages the cap in a plane at right an les to the axis of rotation thereof thus holding the cap against rotation. The lever 3 upon being raised or moved upwardly, disengages its pin 10 from the opening 9 and permits the cap to be rotated as usual.

What is claimed is 1. In combination with a fountain pen having a base and a removable cap, a lever pivoted in the base, a keeper on the cap composed of an openin formed therein, a

projection on the lever ormed to engage in the opening, and snap connections between the lever. sides and the base to latch the lever in position.

2. In combination with a fountain pen having a base and a removable cap, a lever pivoted in the base, a. keeper on'the cap composed of an opening formed therein, a projection on the lever formed toengage in the opening, and means to latch the lever to the base.

3. In combination with a fountain pen having a cap, and a lever carried by the pen body, a keeper on the cap, means carried by the lever to engage the keeper to hold the cap against rotation, and means to latch the lever in position.

4. In combination with a fountain pen having a cap, a lever carried by the pen body, a keeper on the cap, means carried by the lever to engage the keeper to hold the cap against rotation, and means to mount the lever so as to permit same to be moved to lie disengaged from the cap during removal of the latter.

5. In combination with a fountain pen havinga cap, and a lever carried by the pen body, means on the cap disposed exteriorly thereof and engaging the lever whereby the latter holds the cap against movement relative to the pen body and means to mount the lever so as to permit same to be moved to lie disengaged from the cap during removal of the latter.

6. In combination with a fountain pen having a cap, and a lever carried by the penbod means on the cap engaging the ever w ereby the latter holds the cap against movement relative to the pen body and means to latch the lever in engagement with the cap.

7. In combination with a fountain pen having a cap, means engaging the cap from the exterior thereof to removably latch the cap to the pen against rotation relative thereto and means, to mount the latching means to permit same to be moved to lie disengagedirom the cap during rotation of the latter.
