HENRY EDWARD KNIES, 0F WHITE HAVEN, PENNSYLVANIA.

FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Apr. *7, 1914.

Application filed November 7, 19112. Serial No. 730,087.

To all whom 'it may concern Be it known that I, HENRY E. KNIES, a citizen of the United States, residing at White Haven, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Fountain-Pen, of which the following is a specification.

One obfect of the present invention is to provide a fountain pen having a valve actuable by the protecting cap of the pen to cut off the feed duct.

Another object of the invention is to provide a cap having anovel element for actu ating the cut-off valve.

v Another object of the invention is to provide a cut-ofil valve and retracting means therefor, of novel construction.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope o-f what is claimed without departing from the spirit of the invention.

In the drawing :Figure 1 is a fragmental longitudinal section showing the cut-olf valve in advanced position; Fig. 2 is an elevation, parts being broken away, and the cut-off valve being shown in retracted position; Fig. 3 is a fragmental elevation depicting particularly, the retracting spring for the valve; Fig. 4 is a perspective of the valve; Fig. 5 is a perspective of the valve spring; Fig. 6 is an enlarged cross section ofthe feed finger; Fig. 7 is a fragmental longitudinal section, showing a modified form of the invention, parts appearing in elevation; and Fig. 8 is a side elevation of the valve employed in that form of the invention which is depicted in Fig. 7.

In the drawings, the numeral 1 indicates the barrel o-f the pen, into which is threaded or otherwise secured a tubular head 2, inclosing` a feed finger 3, the pen 4 being inserted between the feed finger 3 and the inner surface of the tubular head 2. The feed finger 8 is equipped with a longitudinal, superficial duct 5, establishing communication between the reservoir 6 of the pen and the pen 4. Disposed transversely of the feed finger 3 is a channel 7, the general direction of which is parallel to the base 5a of the duct 5. As shown at 7, the channel 7 proopening 21 and in the channel 7 is a valve 8, f

`which may take the formV of the vpin of rectangular cross section, the valve including -spaced head forming parts 9 and l0, the part 10 preferably being removable.- That portion of the valve which lies between the head forming parts 9 and 10 is received in an opening 12 in a spring plate 11 having an opening 14 adapted to receive a securing element 15 whereby the spring plate may be secured to the outer face of the tubular head 2. If desired, the spring plate 11 may be ofi' set slightly, as shown at 16, so that the securing element 15 may enter the tubular head 2 in alineinent with a diameter of the head, the off set at 16 o'bviously permitting the valve 8 to cooperate in connection with the duct 5, the duct 5 ordinarily being disposed to one side of the longitudinal axis of the head 2.

The invention further includes a removable cap 17, adapted to be received by an abutment 18 upon the barrel 1, the cap 17 having in its interior, a projecting annular rib 19, the inner face of which is beveled as indicated at 20.

In practical operation, when the cap 17 is removed as shown in Fig. 2, the spring plate 1l will retract the valve 8, so that the inner end of the valve is withdrawn across the feed duct 5. The ink, therefore, will iiow freely to the pen point 4. When the cap 17 is mounted in place, the cap will come into engagement with the abutment 18. When the cap 17 is engaged with the abutment 18, the rib 19 will be positioned opposite to the head 10 of the valve 8, the valve being thrust inwardly by the action of the rib 19, so that the inner end of the valve eX- tends across the duct 5. Obviously, since the channel 7 extends beyond the walls of the feed duct 5, as shown at 7a and 7b, a thoroughly efficient closure of the feed duct will be secured. During the mounting of the cap 17 in place, the beveled face 20 of the rib 19 will engage with the head 10 of the valve 8 and advance the valve, the bevel indicated at 20, serving to prevent a binding of the valve, due to the thrusting action of the rib 19.

Referring particularly to Fig. 2, it will be observed that the valve 8 never is retracted entirely out of engagement with the feed finger 3. Consequently, the valve constitutes means for preventing the independent movement between the feed finger and the tubular head 2.

In Figs.` 7 and 8 a modied form of the invention is shown, but it will be understood that all details hereinbefore mentioned in connection with Fig. l, and not hereinafter modified, apply to that form of the invention under discussion.

Referring'to Fig. 7, the tubular head is indicated at 25, the numeral 26 indicating the feed finger, the same having a duct 27. The transverse channel is indicated at 28 and the opening in the head 25 is indicated at 29. A recess 30 is formed in the head 25,

transversely of\the opening 29, the recess 30 receiving the periphery of a resilient washer 31, which may be fashioned from rubber. The washer 31, if desired, may be cemented at its vperiphery in the recess 30. The washer 3l fits closely about the valve 33, and is received within a groove 32, formed in the valve, the washer, if desired, being cemented in the groove 32. The valve 33 is equipped with spaced heads 34 between which a spring 35 is engaged, the spring being of arched construction, and the ends of the spring bearing upon the outer face of the head 25. The function of the spring 35 is to retract the inner end of the valve 22 out of the duct 27. The outermost head 34: is engageable by a rib 37, formed on the cap 36. Under the circumstances last above pointed out, the spring 35 will be flattened down, as shown in Fig. 7. The washer 3l valve sliding in the pen transversely of the duct; a cap having an internal rib; and a spring connecting the valve with the pen to retract the valve, the rib being `adapted to engage directly with the valve independently of the spring and the valve being rigid whereby the valve will be positively thrust, by the action of the rib, through the accumulations in the duct, the valve being located between the point of the pen and the point of attachment between the spring and the pen, whereby the rib will come into direct contact with the rigid valve in the first instance, when the cap is mounted on the pen.

2. In a device of the class described, a barrel; an ink deli very member in the barrel having a duct; a valve slidable in the ink delivery member transversely of the duct; a cap; the barrel having an abutment to receive the open end of the cap; a rib on the interior of the cap, located to engage the valve when the end of the cap is against the abutment, to move said valve inwardly.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
